　以下、本開示の実施形態について、図面を参照して詳細に説明する。 Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.
（第１実施形態）
　図１は、本開示の第１実施形態に係る推定装置（電子機器）の外観斜視図である。推定装置１００は、保持部１１０と、測定機構１２０と、電源保持部１３０とを備える。 (First embodiment)
FIG. 1 is an external perspective view of an estimation apparatus (electronic device) according to the first embodiment of the present disclosure. The estimation apparatus 100 includes a holding unit 110, a measurement mechanism 120, and a power supply holding unit 130.
　保持部１１０は、例えばアーチ形状である。被検者は、保持部１１０で頭部を挟み込むことにより、推定装置１００を装着できる。測定機構１２０は、保持部１１０の第１端１０１側に配置される。電源保持部１３０は、保持部１１０において、第１端１０１とは反対の第２端１０２側に配置される。被検者が推定装置１００を装着した状態において、測定機構１２０は、被検部位である被検者の耳に接触する。 The holding unit 110 has, for example, an arch shape. The subject can wear the estimation device 100 by sandwiching the head with the holding unit 110. The measurement mechanism 120 is disposed on the first end 101 side of the holding unit 110. The power supply holding unit 130 is disposed on the second end 102 side opposite to the first end 101 in the holding unit 110. In a state where the subject wears the estimation device 100, the measurement mechanism 120 comes into contact with the ear of the subject that is the test site.
　推定装置１００は、第１端１０１側に、制御機構保持部１４０を備える。制御機構保持部１４０は、推定装置１００が備える各機能ブロックを制御する制御機構を保持する。推定装置１００が備える各機能ブロックの詳細については、後述する図３の説明において説明する。 The estimation apparatus 100 includes a control mechanism holding unit 140 on the first end 101 side. The control mechanism holding unit 140 holds a control mechanism that controls each functional block included in the estimation apparatus 100. Details of each functional block included in the estimation apparatus 100 will be described in the description of FIG. 3 to be described later.
　被検者は、第１端１０１側の測定機構１２０を例えば左耳に保持し、第２端１０２側に設けられた当接部１５０を右耳の上部に当接させ、保持部１１０が頭頂部を通るようにして、推定装置１００を装着する。被検者は、推定装置１００を装着した状態で、推定装置１００に生体情報を測定させる。本実施形態では、推定装置１００は、被検者の耳に接触する測定機構１２０により、生体情報を測定する。 The subject holds the measurement mechanism 120 on the first end 101 side, for example, in the left ear, makes the contact portion 150 provided on the second end 102 side contact the upper portion of the right ear, and the holding portion 110 is the head. The estimation device 100 is mounted so as to pass through the top. The subject causes the estimation apparatus 100 to measure biological information while wearing the estimation apparatus 100. In this embodiment, the estimation apparatus 100 measures biological information by the measurement mechanism 120 that contacts the subject's ear.
　図２は、図１の測定機構１２０の一例を示す図である。図２に示す測定機構１２０は、被検者の耳珠において生体情報を取得する場合の一例である。測定機構１２０は、挿入部１２１と、接触部１２３とを備える。 FIG. 2 is a diagram illustrating an example of the measurement mechanism 120 in FIG. The measurement mechanism 120 shown in FIG. 2 is an example in the case of acquiring biological information in the subject's tragus. The measurement mechanism 120 includes an insertion part 121 and a contact part 123.
　挿入部１２１は、被検者が推定装置１００を装着した際に、耳の外耳道に挿入される。つまり、被検者は、推定装置１００を装着する際に、挿入部１２１が耳の外耳道に挿入されるように、測定機構１２０を頭部に保持させる。挿入部１２１は、推定装置１００の装着状態を安定させ、接触部１２３と被検部位である耳珠との位置関係を確定させる機能を有する。 The insertion unit 121 is inserted into the ear canal when the subject wears the estimation device 100. That is, when the subject wears the estimation apparatus 100, the subject holds the measurement mechanism 120 on the head so that the insertion unit 121 is inserted into the ear canal of the ear. The insertion unit 121 has a function of stabilizing the wearing state of the estimation device 100 and determining the positional relationship between the contact unit 123 and the tragus that is the test site.
　接触部１２３は、凹形状の部材であり、２つの突出部１２３ａ及び１２３ｂを備える。突出部１２３ａは、被検者が推定装置１００を装着した際に後頭部側に位置する。突出部１２３ｂは、被検者が推定装置１００を装着した際に頭部の正面側に位置する。接触部１２３は、被検者が推定装置１００を装着した際に、２つの突出部１２３ａ及び１２３ｂの間に形成された凹型の窪んだ部分で耳珠を挟み込むようにして、耳珠に接触する。突出部１２３ａの先端側、つまり被検者が推定装置１００を装着した際に頭部側に位置する側には、挿入部１２１が固定されている。 The contact portion 123 is a concave member and includes two projecting portions 123a and 123b. The protrusion 123a is positioned on the back of the head when the subject wears the estimation device 100. The protrusion 123b is located on the front side of the head when the subject wears the estimation device 100. When the subject wears the estimation device 100, the contact portion 123 comes into contact with the tragus so that the tragus is sandwiched between concave concave portions formed between the two protruding portions 123a and 123b. . An insertion portion 121 is fixed to the distal end side of the protruding portion 123a, that is, the side positioned on the head side when the subject wears the estimation device 100.
　接触部１２３は、生体情報を光学的に取得するための生体センサを備える。本実施形態では、生体センサは、突出部１２３ａ又は１２３ｂのいずれかの内部に搭載される。生体センサは、例えば、生体情報としての血流を測定する血流センサであってよい。生体センサの詳細については、後述する。測定機構１２０について、図３及び４を参照して以下にさらに詳細に説明する。 The contact unit 123 includes a biological sensor for optically acquiring biological information. In the present embodiment, the biosensor is mounted inside either the protrusion 123a or 123b. The biological sensor may be, for example, a blood flow sensor that measures blood flow as biological information. Details of the biosensor will be described later. The measurement mechanism 120 is described in further detail below with reference to FIGS.
　測定機構１２０は、被検部位に当接した状態で、被検部位から生体情報を取得する。図３は、被検者が図１の推定装置１００を装着した場合における、左耳での測定機構１２０の保持状態を示す図である。図４は、図３に示す保持状態を頭頂側から見た場合の図である。図４は、図３に示す左耳のＡ－Ａ断面図を含む。測定機構１２０の理解を容易にするために、図３及び図４において、推定装置１００が備える測定機構１２０以外の構成要素については、図示を省略している。例えば、図１及び図２に示されるように、図３に示されるフレーム部１２５の頭部上方側には、制御機構保持部１４０及び保持部１１０が形成されている。しかし、図３では制御機構保持部１４０及び保持部１１０の記載を省略している。以下、本明細書において、頭頂側から見る場合を、上面視とも表現する。 The measurement mechanism 120 acquires biological information from the test site while being in contact with the test site. FIG. 3 is a diagram showing a holding state of the measurement mechanism 120 in the left ear when the subject wears the estimation device 100 of FIG. FIG. 4 is a view when the holding state shown in FIG. 3 is viewed from the top of the head. FIG. 4 includes an AA cross-sectional view of the left ear shown in FIG. In order to facilitate understanding of the measurement mechanism 120, in FIG. 3 and FIG. 4, components other than the measurement mechanism 120 included in the estimation device 100 are not illustrated. For example, as shown in FIGS. 1 and 2, a control mechanism holding part 140 and a holding part 110 are formed on the upper side of the head part of the frame part 125 shown in FIG. 3. However, the control mechanism holding unit 140 and the holding unit 110 are not shown in FIG. Hereinafter, in this specification, the case of viewing from the top of the head is also expressed as a top view.
　測定機構１２０は、挿入部１２１と、押圧部１２２と、接触部１２３と、接続部１２４とを備える。 The measurement mechanism 120 includes an insertion part 121, a pressing part 122, a contact part 123, and a connection part 124.
　挿入部１２１は、被検者が推定装置１００を装着した際に、左耳の外耳道に挿入される。つまり、被検者は、推定装置１００を装着する際に、挿入部１２１が左耳の外耳道に挿入されるように、測定機構１２０を頭部に保持させて、推定装置１００を装着する。 The insertion unit 121 is inserted into the ear canal of the left ear when the subject wears the estimation device 100. That is, when wearing the estimation apparatus 100, the subject wears the estimation apparatus 100 while holding the measurement mechanism 120 on the head so that the insertion unit 121 is inserted into the ear canal of the left ear.
　押圧部１２２は、被検者が推定装置１００を装着した際、つまり挿入部１２１を外耳道に挿入した状態において、耳甲介に当接し、耳甲介を後頭部側に付勢する。耳甲介が後頭部側に付勢されることにより、耳珠の先端側が外耳道の反対方向、つまり顔面側に向かって、外耳道に沿った方向に立つ。これによって、接触部１２３により耳珠を挟み込みやすくなる。 When the subject wears the estimation device 100, that is, when the insertion unit 121 is inserted into the external auditory canal, the pressing unit 122 abuts on the concha and biases the concha to the occipital side. When the concha is biased toward the occipital region, the tip of the tragus stands in the direction opposite to the ear canal, that is, in the direction along the ear canal toward the face. This makes it easier to pinch the tragus with the contact portion 123.
　接触部１２３は、凹型形状の部材であり、２つの突出部１２３ａ及び１２３ｂを備える。突出部１２３ａは、被検者が推定装置１００を装着した際に後頭部側に位置する。突出部１２３ｂは、被検者が推定装置１００を装着した際に頭部の正面側に位置する。接触部１２３は、被検者が推定装置１００を装着した際に、２つの突出部１２３ａ及び１２３ｂの間に形成された凹型の窪んだ部分で耳珠を挟み込むようにして、耳珠に接触する。突出部１２３ａの先端側、つまり被検者が推定装置１００を装着した際に頭部側に位置する側には、挿入部１２１が固定されている。先端側と反対の基端側には、接続部１２４に接続されている。つまり、押圧部１２２と接触部１２３とは、接続部１２４を介して接続されている。 The contact part 123 is a concave-shaped member and includes two projecting parts 123a and 123b. The protrusion 123a is positioned on the back of the head when the subject wears the estimation device 100. The protrusion 123b is located on the front side of the head when the subject wears the estimation device 100. When the subject wears the estimation device 100, the contact portion 123 comes into contact with the tragus so that the tragus is sandwiched between concave concave portions formed between the two protruding portions 123a and 123b. . An insertion portion 121 is fixed to the distal end side of the protruding portion 123a, that is, the side positioned on the head side when the subject wears the estimation device 100. A proximal end side opposite to the distal end side is connected to the connecting portion 124. That is, the pressing part 122 and the contact part 123 are connected via the connection part 124.
　接触部１２３は、生体情報を光学的に取得するための反射型の生体センサ２１０を備える。一実施形態では、接触部１２３は、反射型の生体センサ２１０を備える。反射型の生体センサ２１０は、発光部及び受光部を有する。反射型の生体センサ２１０は、発光部及び受光部の双方が突出部１２３ａに配置される。接触部１２３における反射型の生体センサ２１０の位置は、図４に仮想的に点線で示されている。実際には、反射型の生体センサ２１０は、接触部１２３の内部に搭載されている。 The contact unit 123 includes a reflective biological sensor 210 for optically acquiring biological information. In one embodiment, the contact unit 123 includes a reflective biosensor 210. The reflective biosensor 210 has a light emitting unit and a light receiving unit. In the reflection-type biosensor 210, both the light emitting unit and the light receiving unit are disposed on the protruding portion 123a. The position of the reflective biosensor 210 in the contact portion 123 is virtually indicated by a dotted line in FIG. Actually, the reflective biological sensor 210 is mounted inside the contact portion 123.
　反射型の生体センサ２１０は、被検者の耳珠（被検部位）において生体情報を取得する。反射型の生体センサ２１０による生体情報の取得方法の詳細については、後述する。 The reflection-type biosensor 210 acquires biometric information in the subject's tragus (test site). Details of the biometric information acquisition method by the reflective biosensor 210 will be described later.
　接続部１２４は、押圧部１２２と接触部１２３とを接続する。本実施の形態では、図３及び図４に示すように、接触部１２３は、基端側において接続部１２４と直接接続される。押圧部１２２は、推定装置１００の第１端１０１側のフレーム部１２５を介して接続部１２４と接続されている。接続部１２４は、押圧部１２２と接触部１２３との相対的位置関係を変化させることが可能な可動部材により構成されている。一実施形態では、接続部１２４は、例えばゴム等の弾性部材で構成されていてもよい。接続部１２４は、押圧部１２２と接触部１２３との相対的位置関係を変化させることが可能な材料によって構成されていてもよい。接続部１２４の材料として、例えば、ばね、樹脂、プラスチック、布、繊維等を使用することができる。接続部１２４は、機械的な構造によって、押圧部１２２と接触部１２３との相対的位置関係を変化させることが可能に構成されていてもよい。機械的な構造は、例えば、歯車等を用いて接続部１２４が可動する機構等とすることができる。 The connection part 124 connects the pressing part 122 and the contact part 123. In the present embodiment, as shown in FIGS. 3 and 4, the contact portion 123 is directly connected to the connection portion 124 on the base end side. The pressing unit 122 is connected to the connection unit 124 via the frame unit 125 on the first end 101 side of the estimation device 100. The connection part 124 is comprised by the movable member which can change the relative positional relationship of the press part 122 and the contact part 123. FIG. In one embodiment, the connection part 124 may be comprised by elastic members, such as rubber | gum, for example. The connecting portion 124 may be made of a material that can change the relative positional relationship between the pressing portion 122 and the contact portion 123. For example, a spring, resin, plastic, cloth, fiber, or the like can be used as the material of the connection portion 124. The connection part 124 may be configured to be able to change the relative positional relationship between the pressing part 122 and the contact part 123 by a mechanical structure. The mechanical structure may be, for example, a mechanism in which the connecting portion 124 is movable using a gear or the like.
　接触部１２３は、接続部１２４により、フレーム部１２５に対して変位可能になっている。接触部１２３がフレーム部１２５に対して変位することによって、押圧部１２２と、接触部１２３との相対的位置関係が変化する。このような接続部１２４の構成により接触部１２３がフレーム部１２５に対して変位する。そのため、耳の形状、特に耳甲介と耳珠との位置関係に関わらず、接触部１２３は、耳珠を挟み込むようにして耳珠に接触しやすくなる。図４に示される例では、接触部１２３は、接続部１２４が形成されているフレーム部１２５が有する平面部１２５ａの垂線に対して、約３０°後頭部方向に傾斜している。 The contact portion 123 can be displaced with respect to the frame portion 125 by the connecting portion 124. When the contact part 123 is displaced with respect to the frame part 125, the relative positional relationship between the pressing part 122 and the contact part 123 changes. With such a configuration of the connection portion 124, the contact portion 123 is displaced with respect to the frame portion 125. Therefore, regardless of the shape of the ear, particularly the positional relationship between the concha and the tragus, the contact portion 123 can easily come into contact with the tragus so as to sandwich the tragus. In the example shown in FIG. 4, the contact portion 123 is inclined about 30 ° in the occipital direction with respect to the perpendicular of the flat portion 125 a of the frame portion 125 in which the connection portion 124 is formed.
　図３に示されるようにフレーム部１２５は、推定装置１００を耳に装着した場合に外耳道外側方向に面する平面部１２５ｂを有する。フレーム部１２５の平面部１２５ａの反対面１２５ｂ側の面の略中央に接続部１２４が形成されている。推定装置１００を耳に装着していない状態では、接続部１２４が変形していないため、このフレーム部１２５の平面部１２５ａの反対面１２５ｂに対して略垂直方向に向かって、接続部１２４が形成されている。フレーム部１２５により、被検者は、推定装置１００を耳に装着する場合に、接続部１２４の位置を把握しやすくなり、接続部１２４の先に形成されている挿入部１２１の外耳道への挿入、及び接触部１２３の耳珠への装着を容易に行うことができる。 As shown in FIG. 3, the frame part 125 has a flat part 125b facing the outer ear canal outside direction when the estimation device 100 is worn on the ear. A connecting portion 124 is formed in the approximate center of the surface of the frame portion 125 on the opposite surface 125b side of the flat portion 125a. In a state where the estimation device 100 is not worn on the ear, the connection portion 124 is not deformed, and therefore the connection portion 124 is formed in a direction substantially perpendicular to the opposite surface 125b of the flat surface portion 125a of the frame portion 125. Has been. The frame part 125 makes it easier for the subject to grasp the position of the connection part 124 when the estimation apparatus 100 is worn on the ear, and the insertion part 121 formed at the end of the connection part 124 is inserted into the ear canal. , And the contact part 123 can be easily attached to the tragus.
　本実施形態に係る推定装置１００は、耳珠において生体情報を取得する。耳珠内の血管は、例えば指又は耳朶等の血管と比較して、外気温の影響を受けて拡張又は収縮しにくい。そのため、推定装置１００により取得される生体情報は外気温の影響を受けにくい。これにより、本実施形態に係る推定装置１００によれば、より高い精度で生体情報を測定できる。 The estimation apparatus 100 according to the present embodiment acquires biological information in the tragus. The blood vessels in the tragus are less likely to expand or contract under the influence of the outside air temperature than blood vessels such as fingers or earlobe. Therefore, the biological information acquired by the estimation apparatus 100 is not easily affected by the outside air temperature. Thereby, according to the estimation apparatus 100 which concerns on this embodiment, biometric information can be measured with a higher precision.
　被検者は、推定装置１００を装着した状態で、生体情報を測定する。推定装置１００は、測定した生体情報に基づいて、身体の状態を推定する。生体情報は、例えば血流量を含む。推定装置１００は、生体情報である血流量に基づいて、心臓からの拍出量に関する値及び心拍数を算出する。身体の状態は、心臓からの拍出量に関する値及び心拍数に基づいて推定される。身体の状態は、例えば身体のリラックス状態である。推定装置１００は、例えば被検者がマッサージを受ける前後における身体の状態を推定することにより、マッサージの効果を推定してもよい。本明細書において、マッサージは、指圧等の血液の循環を活性化させる療法を含む。 The subject measures the biological information while wearing the estimation device 100. The estimation apparatus 100 estimates the state of the body based on the measured biological information. The biological information includes, for example, blood flow. The estimation apparatus 100 calculates a value relating to the amount of stroke from the heart and a heart rate based on the blood flow that is biological information. The state of the body is estimated based on the value relating to the stroke volume from the heart and the heart rate. The state of the body is, for example, a relaxed state of the body. The estimation apparatus 100 may estimate the effect of the massage, for example, by estimating the state of the body before and after the subject receives the massage. In this specification, massage includes therapies that activate blood circulation such as finger pressure.
　ここで、マッサージの効果の推定について説明する。被検者がマッサージを受けると、全身から心臓に戻る循環血液量が増加する。心臓に戻る循環血液量が増加すると、心臓から全身に送出される１拍当たりの血液の拍出量（ＳＶ：Stroke Volume）が増加する。ＳＶが増加すると、スターリングの法則により、被検者の脳は、副交感神経を亢進させる。副交感神経が亢進すると、末梢血管が拡張し、心拍数（ＨＲ：Heart Rate）が下降する。副交感神経が優位になると、被検者の身体においてリラックス状態が実現される。従って、マッサージの効果が表れているか否かは、リラックス状態が実現されているか否かによって判定できる。リラックス状態が実現できているか否かは、ＳＶ及びＨＲの変動により検出できる。本実施形態に係る推定装置１００は、ＳＶの変動を検出するために、ＳＶと相関して変動するＳＶに関する値を用いて、リラックス状態が実現されているか否かを推定する。 Here, the estimation of the effect of massage will be explained. When a subject receives a massage, the amount of circulating blood that returns from the whole body to the heart increases. When the amount of circulating blood returning to the heart increases, the stroke volume (SV: Stroke Volume) per beat delivered from the heart to the whole body increases. When SV increases, the subject's brain enhances parasympathetic nerves according to Stirling's law. When the parasympathetic nerve is increased, peripheral blood vessels are dilated and the heart rate (HR) is lowered. When parasympathetic nerves become dominant, a relaxed state is realized in the body of the subject. Therefore, whether or not the effect of the massage appears can be determined by whether or not the relaxed state is realized. Whether or not the relaxed state can be realized can be detected by fluctuations in SV and HR. The estimation apparatus 100 according to the present embodiment estimates whether or not a relaxed state is realized using a value related to SV that varies in correlation with SV in order to detect variation in SV.
　図５は、推定装置１００の概略構成を示す機能ブロック図である。推定装置１００は、生体センサ２１０と、制御部２２０と、入力部２３０と、報知部２４０と、記憶部２５０とを備える。生体センサ２１０は、上述のように接触部１２３の内部に搭載される。制御部２２０及び記憶部２５０は、例えば制御機構保持部１４０に搭載される。入力部２３０及び報知部２４０は、例えば電源保持部１３０又は制御機構保持部１４０に搭載される。 FIG. 5 is a functional block diagram showing a schematic configuration of the estimation apparatus 100.

The input unit 230 and the notification unit 240 are mounted on the power supply holding unit 130 or the control mechanism holding unit 140, for example.
　制御部２２０は、推定装置１００の各機能ブロックをはじめとして、推定装置１００の全体を制御及び管理するプロセッサである。制御部２２０は、制御手順を規定したプログラムを実行するＣＰＵ（Central Processing Unit）等のプロセッサで構成される。このようなプログラムは、例えば記憶部２５０、又は推定装置１００に接続された外部の記憶媒体等に格納される。 The control unit 220 is a processor that controls and manages the entire estimation device 100 including each functional block of the estimation device 100. The control unit 220 includes a processor such as a CPU (Central Processing Unit) that executes a program that defines a control procedure. Such a program is stored in, for example, the storage unit 250 or an external storage medium connected to the estimation apparatus 100.
　推定装置１００は、以下にさらに詳細に述べられるように、種々の機能を実行するための制御及び処理能力を提供するために、少なくとも１つのプロセッサ２２０ａを含む。 The estimation device 100 includes at least one processor 220a to provide control and processing capabilities to perform various functions, as will be described in further detail below.
　種々の実施形態によれば、少なくとも１つのプロセッサ２２０ａは、単一の集積回路（ＩＣ）として、又は複数の通信可能に接続された集積回路ＩＣ及び／又はディスクリート回路（discrete circuits）として実行されてもよい。少なくとも１つのプロセッサ２２０ａは、種々の既知の技術に従って実行されることが可能である。 According to various embodiments, at least one processor 220a may be implemented as a single integrated circuit (IC) or as a plurality of communicatively connected integrated circuit ICs and / or discrete circuits.

The functions of the control unit 220 described below may be executed including any combination of these devices or configurations, or other known devices or combinations of configurations.
　制御部２２０は、生体センサ２１０が取得した生体情報に基づいて、血流量を測定する。制御部２２０は、測定した血流量に基づいて、ＳＶに関する値及びＨＲを算出する。制御部２２０は、測定したＳＶに関する値及びＨＲに基づいて、身体の状態を推定する。制御部２２０が実行する身体の状態の推定処理の詳細については、後述する。 The control unit 220 measures the blood flow based on the biological information acquired by the biological sensor 210. The control unit 220 calculates a value related to SV and HR based on the measured blood flow rate. The controller 220 estimates the state of the body based on the measured SV value and HR. Details of the body state estimation processing executed by the control unit 220 will be described later.
　生体センサ２１０は、発光部２１１及び受光部２１２を備える。生体センサ２１０は、発光部２１１から、被検部位である耳珠に測定光を照射する。生体センサ２１０は、受光部２１２において、照射された測定光に対する耳珠内部の組織からの反射光（散乱光）を取得する。生体センサ２１０は、受光部２１２が取得した散乱光の光電変換信号を、制御部２２０に送信する。 The biosensor 210 includes a light emitting unit 211 and a light receiving unit 212. The biosensor 210 irradiates measurement light from the light emitting unit 211 to the tragus which is a test site. The biosensor 210 acquires reflected light (scattered light) from the tissue inside the tragus for the irradiated measurement light in the light receiving unit 212. The biosensor 210 transmits the photoelectric conversion signal of the scattered light acquired by the light receiving unit 212 to the control unit 220.
　発光部２１１は、制御部２２０の制御に基づいてレーザ光を射出する。発光部２１１は、例えば、血液中に含まれる所定の成分を検出可能な波長のレーザ光を、測定光として被検部位に照射する。発光部２１１は、例えば１つのＬＤ（レーザダイオード：Laser Diode）により構成される。 The light emitting unit 211 emits laser light based on the control of the control unit 220. For example, the light emitting unit 211 irradiates a test site with laser light having a wavelength capable of detecting a predetermined component contained in blood as measurement light. The light emitting unit 211 is configured by, for example, one LD (Laser Diode: Laser Diode).
　受光部２１２は、生体情報として、被検部位からの測定光の散乱光を受光する。受光部２１２は、例えば、ＰＤ（フォトダイオード：Photo diode）により構成される。 The light receiving unit 212 receives the scattered light of the measurement light from the test site as biological information. The light receiving unit 212 is configured by, for example, a PD (photodiode).
　制御部２２０は、生体センサ２１０から受信した光電変換信号に基づいて、生体情報として、被検部位における血流量を算出する。ここで、制御部２２０による、ドップラーシフトを利用した血流量測定技術について説明する。 The control unit 220 calculates the blood flow rate at the test site as biological information based on the photoelectric conversion signal received from the biological sensor 210. Here, a blood flow measurement technique using the Doppler shift by the control unit 220 will be described.
　生体の組織内において、動いている血球から散乱された散乱光は、血液中の血球の移動速度に比例したドップラー効果による周波数シフト（ドップラーシフト）を受ける。制御部２２０は、静止した組織からの散乱光と、動いている血球からの散乱光との光の干渉によって生じるうなり信号（ビート信号ともいう）を検出する。このうなり信号は、強度を時間の関数として表したものである。そして、制御部２２０は、このうなり信号を、パワーを周波数の関数として表したパワースペクトルにする。このうなり信号のパワースペクトルでは、ドップラーシフト周波数は血球の速度に比例する。このうなり信号のパワースペクトルでは、パワーは血球の量に対応する。制御部２２０は、うなり信号のパワースペクトルに周波数をかけて積分することにより血流量を求める。 Scattered light scattered from moving blood cells in a living tissue undergoes a frequency shift (Doppler shift) due to the Doppler effect proportional to the moving speed of the blood cells in the blood. The control unit 220 detects a beat signal (also referred to as a beat signal) generated by light interference between scattered light from a stationary tissue and scattered light from a moving blood cell. This beat signal represents the intensity as a function of time. And the control part 220 makes this beat signal the power spectrum which represented power as a function of frequency. In the power spectrum of this beat signal, the Doppler shift frequency is proportional to the blood cell velocity. In the power spectrum of this beat signal, the power corresponds to the amount of blood cells. The controller 220 obtains the blood flow rate by integrating the power spectrum of the beat signal over the frequency.
　図６は、推定装置１００により取得される血流波形の一例を示す模式図である。図６に示される血流波形は、被検者の脈拍１拍分の血流波形である。図６に示される血流波形は、血流量の変化を示す波形であり、例えば制御部２２０が算出した血流量に基づいて生成される。制御部２２０は、血流量に基づいて生成される血流波形から、ＳＶに関する値及びＨＲを算出する。 FIG. 6 is a schematic diagram illustrating an example of a blood flow waveform acquired by the estimation apparatus 100. The blood flow waveform shown in FIG. 6 is a blood flow waveform for one pulse of the subject. The blood flow waveform shown in FIG. 6 is a waveform indicating a change in blood flow, and is generated based on the blood flow calculated by the control unit 220, for example. The control unit 220 calculates a value related to SV and HR from a blood flow waveform generated based on the blood flow volume.
　ここで、ＳＶに関する値について説明する。ＳＶに関する値は、ＳＶの変動と相関関係を有する任意の値である。ＳＶに関する値は、例えば、脈動により変化する血流の波高（脈動血流波高ｑｐｐ）である。脈動血流波高ｑｐｐは、図６に示すように、１拍の脈拍における血流量の最大の差分である。ＳＶに関する値は、例えば、脈動により変化する血流の脈拍１拍当たりの血流量（脈動血流量）であってもよい。脈動血流量は、図６に斜線を付した領域で示すように、１拍の脈拍における血流波形の変動域における血流量である。脈動血流量は、１拍の脈拍における血流波形の変動域における積分値として算出される。脈動血流波高ｑｐｐ及び脈動血流量等は、心臓から送出されるＳＶが多くなるほど高く（多く）なる。そのため、制御部２２０は、脈動血流波高ｑｐｐ及び脈動血流量等のＳＶに関する値の変化に基づいて、ＳＶの変動を推定できる。ＳＶに関する値は、例えば所定の数拍分の脈動血流波高ｑｐｐ又は脈動血流量の平均値であってもよい。本開示において、ｘとｙとの相関とは、ｘとｙとが密接にかかわり合っていることをいい、この相関の関係を示す数値として、後述する相関係数を用いる。 Here, the value regarding SV is demonstrated. The value related to SV is an arbitrary value having a correlation with the variation of SV. The value regarding SV is, for example, the wave height of the blood flow that changes due to pulsation (pulsation blood flow wave height q pp ). The pulsating blood flow wave height q pp is the maximum difference in blood flow volume in one pulse as shown in FIG. The value related to SV may be, for example, a blood flow rate (pulse blood flow rate) per pulse of blood flow that changes due to pulsation. The pulsating blood flow rate is the blood flow rate in the fluctuation region of the blood flow waveform in one pulse as shown by the hatched region in FIG. The pulsating blood flow is calculated as an integrated value in the fluctuation region of the blood flow waveform in one pulse. The pulsating blood flow height q pp, the pulsating blood flow rate, and the like increase (increase) as the SV delivered from the heart increases. Therefore, the control unit 220, based on the change of the pulsating blood flow crest q pp and pulsating values for SV blood flow rate, etc., can estimate the fluctuation of the SV. The value related to SV may be, for example, a predetermined several beats of pulsating blood flow wave height q pp or an average value of pulsating blood flow. In the present disclosure, the correlation between x and y means that x and y are closely related, and a correlation coefficient described later is used as a numerical value indicating the correlation.
　ＳＶに関する値は、例えば、血流量、血流速度又は血液量であってもよい。血流量は、単位時間当たりに血管の所定の位置を流れる血液の量（体積）である。血流速度は、血管の所定の位置を流れる血液の速度である。血液量は、血管の所定の位置における血液の量である。ただし、ＳＶに関する値は、ここに示すものに限られない。 The value related to SV may be, for example, a blood flow volume, a blood flow velocity, or a blood volume. The blood flow rate is the amount (volume) of blood flowing through a predetermined position of the blood vessel per unit time. The blood flow velocity is the velocity of blood flowing through a predetermined position of the blood vessel. The blood volume is the volume of blood at a predetermined position in the blood vessel. However, the value regarding SV is not restricted to what is shown here.
　ＨＲは、血流量に基づいて生成される血流波形の単位時間当たりのピーク数から、制御部２２０により算出される。 HR is calculated by the control unit 220 from the number of peaks per unit time of the blood flow waveform generated based on the blood flow volume.
　制御部２２０は、ＳＶに関する値及びＨＲの変動を算出することにより、身体の状態を推定する。制御部２２０による身体の状態の推定処理の詳細については、後述する。 The control unit 220 estimates the state of the body by calculating a value related to SV and a change in HR. Details of the estimation process of the body state by the control unit 220 will be described later.
　入力部２３０は、被検者からの操作入力を受け付けるものであり、例えば、操作ボタン（操作キー）から構成される。入力部２３０をタッチパネルにより構成し、表示デバイスの一部に被検者からの操作入力を受け付ける操作キーを表示して、被検者によるタッチ操作入力を受け付けてもよい。 The input unit 230 receives an operation input from the subject, and includes an operation button (operation key), for example. The input unit 230 may be configured by a touch panel, and an operation key that receives an operation input from the subject may be displayed on a part of the display device to accept a touch operation input by the subject.
　報知部２４０は、音、振動、及び画像等で情報を報知する。報知部２４０は、スピーカ、振動子、及び表示デバイスを備えていてもよい。表示デバイスは、例えば液晶ディスプレイ（ＬＣＤ：Liquid Crystal Display）、有機ＥＬディスプレイ（ＯＥＬＤ：Organic Electro-Luminescence Display）、又は無機ＥＬディスプレイ（ＩＥＬＤ：Inorganic Electro-Luminescence Display）等とすることができる。報知部２４０は、例えば身体の状態及び後述するマッサージの効果等を報知する。 The notification unit 240 notifies information using sound, vibration, images, and the like. The notification unit 240 may include a speaker, a vibrator, and a display device. The display device may be, for example, a liquid crystal display (LCD: Liquid Crystal Display), an organic EL display (OELD: Organic Electro-Luminescence Display), or an inorganic EL display (IELD: Inorganic Electro-Luminescence Display). The notification unit 240 notifies, for example, the state of the body and the effect of massage to be described later.
　記憶部２５０は、半導体メモリ又は磁気メモリ等で構成されることができる。記憶部２５０は、各種情報及び／又は推定装置１００を動作させるためのプログラム等を記憶する。記憶部２５０は、ワークメモリとしても機能してもよい。記憶部２５０は、例えば、生体センサ２１０により取得された生体情報を記憶してもよい。 The storage unit 250 can be composed of a semiconductor memory or a magnetic memory. The storage unit 250 stores various information and / or a program for operating the estimation apparatus 100 and the like. The storage unit 250 may function as a work memory. The storage unit 250 may store biometric information acquired by the biosensor 210, for example.
　次に、推定装置１００による生体情報の測定及び身体の状態の推定の処理について、図７を参照しながら説明する。ここでは、被検者がマッサージチェア等のマッサージ装置によるマッサージを受ける場合の例について説明する。推定装置１００は、身体の状態として身体がリラックス状態であるか否かを推定することにより、マッサージの効果を判定する。被検者が例えばマッサージ師によるマッサージを受ける場合にも、推定装置１００は、下記説明と同様の要領でマッサージの効果を判定できる。 Next, the process of measuring biological information and estimating the state of the body by the estimation apparatus 100 will be described with reference to FIG. Here, an example in which the subject receives a massage by a massage device such as a massage chair will be described. The estimation apparatus 100 determines the effect of the massage by estimating whether the body is in a relaxed state as the body state. Even when the subject receives a massage by a masseur, for example, the estimation apparatus 100 can determine the effect of the massage in the same manner as described below.
　被検者は、マッサージを受ける前に推定装置１００を装着して、推定装置１００による測定処理を開始するための所定の操作入力を行う。図７に示すフローは、当該所定の操作入力を行うと開始される。 The subject wears the estimation device 100 before receiving a massage, and performs a predetermined operation input for starting the measurement process by the estimation device 100. The flow shown in FIG. 7 is started when the predetermined operation input is performed.
　推定装置１００は、まず基底血流量を測定する（ステップＳ１０１）。基底血流量は、マッサージを受ける前の血流量である。推定装置１００は、生体センサ２１０により生体情報として基底血流量を測定する。 The estimation apparatus 100 first measures the basal blood flow (step S101). The basal blood flow is the blood flow before receiving a massage. The estimation apparatus 100 measures the basal blood flow as biological information by the biological sensor 210.
　推定装置１００は、ステップＳ１０１で測定した基底血流量に基づき、ＳＶに関する値及びＨＲを算出する（ステップＳ１０２）。ＳＶに関する値及びＨＲの算出方法については、上述の説明の通りである。 The estimation apparatus 100 calculates a value related to SV and HR based on the basal blood flow measured in step S101 (step S102). The SV value and the HR calculation method are as described above.
　推定装置１００がＳＶに関する値及びＨＲを算出した後、マッサージ装置は、被検者へのマッサージを開始する。推定装置１００は、ＳＶに関する値及びＨＲを算出した場合、当該算出を完了したことを報知部２４０から報知してもよい。これにより、被検者は、マッサージを開始するタイミングを知ることができる。 After the estimation device 100 calculates the SV value and HR, the massage device starts massage for the subject. When the estimation device 100 calculates the SV-related value and HR, the notification device 240 may notify that the calculation has been completed. Thereby, the subject can know the timing which starts a massage.
　推定装置１００は、被検者がマッサージを受けている間の血流量を測定する（ステップＳ１０３）。推定装置１００は、ステップＳ１０１と同様に、生体センサ２１０により生体情報として血流量を測定する。 The estimation apparatus 100 measures the blood flow while the subject is receiving massage (step S103). The estimation apparatus 100 measures the blood flow volume as biological information by the biological sensor 210 as in step S101.
　推定装置１００は、ステップＳ１０３で測定した血流量に基づき、ＳＶに関する値及びＨＲを算出する（ステップＳ１０４）。 The estimation apparatus 100 calculates a value related to SV and HR based on the blood flow measured in step S103 (step S104).
　推定装置１００は、ステップＳ１０４で算出したＳＶに関する値及びＨＲに基づき、身体の状態を推定する（ステップＳ１０５）。推定装置１００は、例えば、ステップＳ１０２で算出した、マッサージ前のＳＶに関する値及びＨＲと、ステップＳ１０４で算出した、マッサージ中のＳＶに関する値及びＨＲとを比較して、身体の状態を推定してよい。推定装置１００は、ＳＶに関する値又はＨＲの一方に基づいて身体の状態を推定してもよい。 The estimation apparatus 100 estimates the state of the body based on the SV-related value and HR calculated in step S104 (step S105). For example, the estimation apparatus 100 estimates the body state by comparing the value and HR related to the SV before massage calculated in step S102 with the value and HR related to the SV during massage calculated in step S104. Good. The estimation apparatus 100 may estimate the state of the body based on one of the value related to SV or HR.
　例えば、マッサージ前のＳＶに関する値とマッサージ中のＳＶに関する値との比較に基づいて、マッサージ前よりもマッサージ中の方がＳＶが増加しているとする。この場合、推定装置１００は、マッサージ前と比較して、マッサージ中に身体がリラックス状態になっていると推定できる。一方、例えば、マッサージ前のＳＶに関する値とマッサージ中のＳＶに関する値との比較に基づいて、マッサージ前よりもマッサージ中の方がＳＶが減少しているとする。この場合、推定装置１００は、身体がリラックス状態になっていないと推定できる。 For example, based on the comparison between the value related to the SV before the massage and the value related to the SV during the massage, it is assumed that the SV during the massage is higher than that before the massage. In this case, the estimation apparatus 100 can estimate that the body is in a relaxed state during the massage as compared to before the massage. On the other hand, for example, based on the comparison between the value related to the SV before massage and the value related to the SV during massage, it is assumed that the SV is decreasing during the massage than before the massage. In this case, the estimation apparatus 100 can estimate that the body is not in a relaxed state.
　例えば、マッサージ前のＨＲよりもマッサージ中のＨＲが下降している場合、推定装置１００は、マッサージ前と比較して、マッサージ中に身体がリラックス状態になっていると推定できる。一方、例えば、マッサージ前のＨＲよりもマッサージ中のＨＲが上昇している場合、推定装置１００は、身体がリラックス状態になっていないと推定できる。他の例として、例えば、マッサージ前のＳＶに関する値及びＨＲと、マッサージ中のＳＶに関する値及びＨＲとの比較に基づいて、マッサージ前よりもマッサージ中の方がＳＶが増加し、かつ、ＨＲが低下しているとする。この場合、推定装置１００は、マッサージ前と比較して、マッサージ中に身体がリラックス状態になっていると推定できる。一方、例えば、マッサージ前のＳＶに関する値及びＨＲとマッサージ中のＳＶに関する値及びＨＲの比較に基づいて、マッサージ前よりもマッサージ中の方がＳＶが減少し、又は、ＨＲが上昇しているとする。この場合、推定装置１００は、身体がリラックス状態になっていないと推定できる。他の例として、例えば、マッサージ前のＳＶに関する値及びＨＲと、マッサージ中のＳＶに関する値及びＨＲとの比較に基づいて、マッサージ前よりもマッサージ中の方がＳＶが増加し、ＨＲが低下していることのいずれか１つがみたされた場合に、推定装置１００は、マッサージ前と比較して、マッサージ中に身体がリラックス状態になっていると推定してもよい。 For example, when the HR during the massage is lower than the HR before the massage, the estimation apparatus 100 can estimate that the body is in a relaxed state during the massage as compared to before the massage. On the other hand, for example, when the HR during the massage is higher than the HR before the massage, the estimation device 100 can estimate that the body is not in a relaxed state. As another example, for example, based on the comparison between the value and HR related to SV before massage and the value and HR related to SV during massage, SV increases during massage than before massage, and HR Suppose that it is falling. In this case, the estimation apparatus 100 can estimate that the body is in a relaxed state during the massage as compared to before the massage. On the other hand, for example, based on the comparison between the value related to SV before massage and the value related to SV and HR during massage and HR, SV is decreasing or HR is increasing during massage than before massage. To do. In this case, the estimation apparatus 100 can estimate that the body is not in a relaxed state. As another example, for example, based on a comparison between the SV value and HR before massage and the SV value and HR during massage, SV increases and HR decreases during massage than before massage. When any one of the above is observed, the estimation apparatus 100 may estimate that the body is in a relaxed state during the massage as compared to before the massage.
　推定装置１００は、ステップＳ１０５で推定した身体の状態に基づき、マッサージの効果を判定する（ステップＳ１０６）。推定装置１００は、例えば、マッサージ前と比較してマッサージ中の方が身体がリラックス状態になっている場合、マッサージの効果がある又はマッサージの効果が高いと判定する。一方、推定装置１００は、例えば、マッサージ前と比較してもマッサージ中の身体がリラックス状態になっていない場合、マッサージの効果がない又はマッサージの効果が低いと判定する。 The estimation apparatus 100 determines the effect of the massage based on the body state estimated in step S105 (step S106). For example, when the body is in a relaxed state during the massage, the estimating apparatus 100 determines that there is a massage effect or a high massage effect compared to before the massage. On the other hand, for example, when the body during the massage is not in a relaxed state, the estimating apparatus 100 determines that there is no massage effect or the massage effect is low when compared to before the massage.
　推定装置１００は、ステップＳ１０６で判定したマッサージの効果を報知する（ステップＳ１０７）。被検者は、推定装置１００の報知内容に基づき、マッサージの継続の要否及びマッサージ内容の適否を判断できる。例えば、マッサージの効果がある又はマッサージの効果が高い旨の報知がされた場合、被検者は、マッサージを継続すると決定できる。例えば、マッサージの効果がない又はマッサージの効果が低い旨の報知がされた場合、被検者は、マッサージ装置によるマッサージを中断したり、マッサージ内容を変更したりすることを決定できる。 The estimation apparatus 100 notifies the massage effect determined in step S106 (step S107). The subject can determine whether or not to continue the massage and suitability of the massage content based on the notification content of the estimation device 100. For example, when notification that there is a massage effect or a massage effect is high is given, the subject can determine to continue the massage. For example, when a notification that there is no massage effect or a massage effect is low, the subject can decide to interrupt the massage by the massage device or change the massage content.
　推定装置１００は、被検者がマッサージを受けている間、ステップＳ１０３からステップＳ１０７を繰り返して実行してもよい。推定装置１００は、マッサージが終了した後に、ステップＳ１０４からステップＳ１０７で示される動作を行い、マッサージ効果を推定してもよい。この場合、推定装置１００は、マッサージが終了した後の短い時間（例えば５秒後、１０秒後又は１分後等）の後、ステップＳ１０４からステップＳ１０７で示される動作を行い、マッサージ効果を推定してもよい。 The estimation apparatus 100 may repeatedly execute Step S103 to Step S107 while the subject is receiving massage. The estimation device 100 may estimate the massage effect by performing the operations shown in steps S104 to S107 after the massage is completed. In this case, the estimation device 100 estimates the massage effect by performing the operations shown in steps S104 to S107 after a short time after the massage is finished (for example, 5 seconds, 10 seconds, or 1 minute). May be.
　推定装置１００は、ステップＳ１０３からステップＳ１０７を繰返し実行する場合、ステップＳ１０５において、所定時間（例えば３分）間隔で、ＳＶに関する値及びＨＲを比較することにより、身体の状態を推定してもよい。ＳＶに関する値及びＨＲの比較は、例えば、所定時間又は所定拍数におけるＳＶに関する値及びＨＲの平均値を比較してもよい。これにより、推定装置１００は、例えば継続的にマッサージを行っている間に、身体の状態（リラックス状態）の変化を推定できる。推定装置１００は、ステップＳ１０６において、所定時間間隔におけるマッサージの効果を判定できる。ステップＳ１０７でマッサージの効果の報知を受けた被検者は、報知内容に基づき、マッサージの継続の要否及びマッサージ内容の適否を判断できる。このように、推定装置１００がステップＳ１０３からステップＳ１０７を繰り返す場合、被検者は、マッサージ中におけるマッサージの効果の変化を知ることができる。 When repeatedly executing step S103 to step S107, the estimating apparatus 100 may estimate the state of the body by comparing the SV-related value and the HR at predetermined time (eg, 3 minutes) intervals in step S105. . For the comparison of the value related to SV and HR, for example, the value related to SV and the average value of HR at a predetermined time or a predetermined number of beats may be compared. Thereby, the estimation apparatus 100 can estimate the change of the body state (relaxed state), for example, while performing massage continuously. In step S106, the estimating apparatus 100 can determine the effect of massage at a predetermined time interval. The subject who has received the massage effect notification in step S107 can determine whether or not to continue the massage and whether or not the massage content is appropriate based on the notification content. Thus, when the estimation apparatus 100 repeats step S103 to step S107, the subject can know the change in the effect of the massage during the massage.
　図８Ａ及び図８Ｂは、血流波形の推移の一例を示す模式図である。図８Ａに示す例では、時間の経過に伴い、血流波高が高くなり、脈拍のピークの間隔Ｉが広がっている。すなわち、図８Ａに示す例では、時間の経過に伴い、ＳＶに関する値（脈動血流波高又は脈動血流量）が増加し、ＨＲが下降している。この現象は、副交感神経が優位になっている状態を示す。この場合、推定装置１００は、身体がリラックス状態に推移していると推定できる。 8A and 8B are schematic diagrams showing an example of the transition of blood flow waveform. In the example shown in FIG. 8A, the blood flow wave height increases with the passage of time, and the pulse peak interval I increases. That is, in the example shown in FIG. 8A, with time, the value related to SV (pulsating blood flow height or pulsating blood flow) increases and HR decreases. This phenomenon indicates a state in which parasympathetic nerves are dominant. In this case, the estimating apparatus 100 can estimate that the body is in a relaxed state.
　一方、図８Ｂに示す例では、時間の経過に伴い、血流波高が低くなり、脈拍のピークの間隔Ｉが狭まっている。すなわち、図８Ｂに示す例では、時間の経過に伴い、ＳＶに関する値（脈動血流波高又は脈動血流量）が減少し、ＨＲが上昇している。この現象は、交感神経が優位になっている状態を示す。この場合、推定装置１００は、身体がリラックス状態でなくなっていると推定できる。 On the other hand, in the example shown in FIG. 8B, with the passage of time, the blood flow wave height decreases, and the pulse peak interval I narrows. That is, in the example shown in FIG. 8B, the value (SV pulse height or pulsating blood flow) related to SV decreases and HR increases with time. This phenomenon indicates a state in which the sympathetic nerve is dominant. In this case, the estimation apparatus 100 can estimate that the body is no longer in a relaxed state.
　このように、第１実施形態に係る推定装置１００によれば、ＳＶに関する値及びＨＲに基づいて身体の状態を推定する。推定装置１００は、ＳＶに関する値又はＨＲの一方に基づいて身体の状態を推定してもよい。ＳＶに関する値は、心臓から全身に送出される血流量と相関する値、すなわち血管内を流れる血流量と相関する値であるため、例えば血管の弾性等、血管の性質の影響を受けにくい値である。ＨＲも血管の性質の影響を受けにくい。このように、推定装置１００は、血管の性質の影響を受けにくい値を用いて、被検者の身体の状態を推定するため、身体の状態の推定精度を向上可能である。推定装置１００は、身体の状態に基づいて、マッサージの効果も推定可能である。推定装置１００は、身体の状態の推定精度を向上可能であるため、身体の状態に基づいて推定されるマッサージの効果の推定精度も向上可能である。推定装置１００がマッサージの効果を報知部２４０から報知することにより、被検者はマッサージの効果を認識できる。 Thus, according to the estimation apparatus 100 according to the first embodiment, the state of the body is estimated based on the value related to SV and the HR. The estimation apparatus 100 may estimate the state of the body based on one of the value related to SV or HR. The value related to SV is a value that correlates with the blood flow amount delivered from the heart to the whole body, that is, a value that correlates with the blood flow amount flowing in the blood vessel, and is a value that is not easily affected by the properties of the blood vessel, such as the elasticity of the blood vessel. is there. HR is also less susceptible to blood vessel properties. Thus, since the estimation apparatus 100 estimates the state of the subject's body using values that are not easily affected by the properties of blood vessels, the estimation accuracy of the state of the body can be improved. The estimation apparatus 100 can also estimate the effect of massage based on the state of the body. Since the estimation apparatus 100 can improve the estimation accuracy of the body state, the estimation accuracy of the effect of the massage estimated based on the body state can also be improved. When the estimation apparatus 100 notifies the effect of the massage from the notification unit 240, the subject can recognize the effect of the massage.
（第２実施形態）
　図９は、本開示の第２実施形態に係る推定装置２００の概略構成を示す機能ブロック図である。本実施形態に係る推定装置２００は、生体センサ２１０と、プロセッサ２２０ａを備える制御部２２０と、入力部２３０と、報知部２４０と、記憶部２５０と、体温測定部２６０と、血圧測定部２７０とを備える。生体センサ２１０、入力部２３０、報知部２４０及び記憶部２５０の各機能については、第１実施形態で説明したものと同様であるため、ここでは説明を省略する。 (Second Embodiment)
FIG. 9 is a functional block diagram illustrating a schematic configuration of the estimation apparatus 200 according to the second embodiment of the present disclosure. The estimation apparatus 200 according to the present embodiment includes a biological sensor 210, a control unit 220 including a processor 220a, an input unit 230, a notification unit 240, a storage unit 250, a body temperature measurement unit 260, and a blood pressure measurement unit 270. Is provided. Since the functions of the biosensor 210, the input unit 230, the notification unit 240, and the storage unit 250 are the same as those described in the first embodiment, description thereof is omitted here.
　体温測定部２６０は、被検者の体温を測定する。体温測定部２６０は、例えば体温計により構成されていてもよい。体温測定部２６０は、例えば図１の測定機構１２０に搭載される。この体温測定部２６０は、例えば液体若しくは気体などの熱膨張を測定して体温を読み取るアナログ式、又は、マイコンで制御されたサーミスタ若しくは赤外線検知回路などで体温を測定するデジタル式などを用いることができる。本実施形態では、デジタル式を用いる。 Body temperature measuring unit 260 measures the body temperature of the subject. The body temperature measurement unit 260 may be constituted by a thermometer, for example. The body temperature measurement unit 260 is mounted on, for example, the measurement mechanism 120 in FIG. The body temperature measurement unit 260 may use, for example, an analog type that measures thermal expansion of a liquid or gas to read the body temperature, or a digital type that measures body temperature with a thermistor or infrared detection circuit controlled by a microcomputer. it can. In this embodiment, a digital type is used.
　血圧測定部２７０は、被検者の血圧値を測定する。血圧測定部２７０は、例えば血圧計により構成されていてもよい。推定装置２００は、血圧測定部２７０として、血圧値を算出するための生体測定出力を取得する機構を備え、制御部２２０が、当該生体測定出力に基づいて被検者の血圧値を算出してもよい。この血圧計は、水銀柱を用いてコロトコフ音を聴診器で聞き取りながら血圧を測定する装置、又は、コロトコフ音をマイクロフォン電子機器測定する電子式の血圧計などであってよい。これらの血圧計以外の血圧計を利用することもできる。 The blood pressure measurement unit 270 measures the blood pressure value of the subject. The blood pressure measurement unit 270 may be configured by a blood pressure monitor, for example. The estimation apparatus 200 includes, as the blood pressure measurement unit 270, a mechanism that acquires a biological measurement output for calculating a blood pressure value, and the control unit 220 calculates a blood pressure value of the subject based on the biological measurement output. Also good. The sphygmomanometer may be a device that measures blood pressure while listening to Korotkoff sounds with a stethoscope using a mercury column, or an electronic sphygmomanometer that measures Korotkoff sounds with a microphone electronic device. Sphygmomanometers other than these sphygmomanometers can also be used.
　本実施形態に係る推定装置２００は、第１実施形態に係る推定装置１００と同様に、制御部２２０において、血流量に基づいてＳＶに関する値及びＨＲを算出する。 The estimation device 200 according to the present embodiment calculates the value and HR related to the SV based on the blood flow rate in the control unit 220, similarly to the estimation device 100 according to the first embodiment.
　本実施形態では、制御部２２０は、ＳＶに関する値、ＨＲ、被検者の体温及び被検者の血圧値に基づいて、身体の状態を推定する。 In the present embodiment, the control unit 220 estimates the state of the body based on the SV-related value, HR, the subject's body temperature, and the subject's blood pressure value.
　例えば、被検者がマッサージを受けると、全身から心臓に戻る血流量が増加し、これに伴って心臓から全身に送出される１拍当たりのＳＶが増加する。ＳＶが増加すると、体温が上昇する。すなわち、マッサージを受ける前と比較して、マッサージ中に体温が上昇している場合、リラックス状態が実現されており、マッサージの効果が表れていると言える。 For example, when the subject receives a massage, the blood flow returning from the whole body to the heart increases, and accordingly, the SV per beat delivered from the heart to the whole body increases. As SV increases, body temperature increases. That is, it can be said that the relaxed state is realized and the effect of the massage appears when the body temperature rises during the massage as compared to before the massage.
　人体は、ＳＶが増加した場合であっても、血圧値を一定に維持しようとする働きを有する。そのため、マッサージを受ける前と、マッサージ中とで、血圧値の変化が小さい方が、リラックス状態となっていると言える。 The human body has a function to keep the blood pressure value constant even when the SV increases. Therefore, it can be said that the one where the change in the blood pressure value is small before the massage and during the massage is in a relaxed state.
　制御部２２０は、上記体温及び血圧値の変化の傾向を踏まえ、マッサージ前とマッサージ中とのＳＶに関する値、ＨＲ、体温及び血圧値の総合的な比較に基づいて、身体の状態を推定する。そして、制御部２２０は、推定した身体の状態に基づき、マッサージの効果を判定する。 The control unit 220 estimates the state of the body based on the comprehensive comparison of the SV-related values, HR, body temperature, and blood pressure values before and during the massage, based on the tendency of the body temperature and blood pressure values to change. And the control part 220 determines the effect of a massage based on the estimated body state.
　例えば、マッサージ前のＳＶに関する値、ＨＲ、体温及び血圧と、マッサージ中のＳＶに関する値、ＨＲ、体温及び血圧との比較に基づいて、マッサージ前よりもマッサージ中の方がＳＶが増加し、ＨＲが低下し、体温が上昇し、かつ、マッサージ前とマッサージ中との血圧値の変化が小さいとする。この場合、推定装置１００は、マッサージ前と比較して、マッサージ中に身体がリラックス状態になっていると推定できる。一方、例えば、マッサージ前のＳＶに関する値、ＨＲ、体温及び血圧と、マッサージ中のＳＶに関する値、ＨＲ、体温及び血圧の比較に基づいて、マッサージ前よりもマッサージ中の方がＳＶが減少し、ＨＲが上昇し、体温が低下し、又はマッサージ前とマッサージ中との血圧値の変化が大きいとする。この場合、推定装置１００は、身体がリラックス状態になっていないと推定できる。他の例として、例えば、マッサージ前のＳＶに関する値、ＨＲ、体温及び血圧と、マッサージ中のＳＶに関する値、ＨＲ、体温及び血圧との比較に基づいて、マッサージ前よりもマッサージ中の方が、ＳＶが増加し、ＨＲが低下し、体温が上昇し、及びマッサージ前とマッサージ中との血圧値の変化が小さいことのいずれか１つ、いずれか２つ又はいずれか３つが満たされているとする。この場合、推定装置１００は、マッサージ前と比較して、マッサージ中に身体がリラックス状態になっていると推定してもよい。 For example, based on the comparison of the SV value, HR, body temperature and blood pressure before massage with the SV value, HR, body temperature and blood pressure during massage, SV increases during massage than before massage. Suppose that the body temperature rises, and the change in blood pressure before and during massage is small. In this case, the estimation apparatus 100 can estimate that the body is in a relaxed state during the massage as compared to before the massage. On the other hand, for example, based on the comparison of the SV value before massage, HR, body temperature and blood pressure, and the SV value during massage, HR, body temperature and blood pressure, the SV during massage is less than before massage, It is assumed that HR increases, body temperature decreases, or a change in blood pressure value between before and during massage is large. In this case, the estimation apparatus 100 can estimate that the body is not in a relaxed state. As another example, for example, based on a comparison of the value, SV, HR, body temperature and blood pressure regarding SV before massage, and the value, SV, HR, body temperature, and blood pressure during massage, those who are massaged more than before massage, If any one of SV increases, HR decreases, body temperature rises, and changes in blood pressure between massage before and during massage are small, any two, or any three are satisfied To do. In this case, the estimation apparatus 100 may estimate that the body is in a relaxed state during the massage as compared to before the massage.
　推定装置２００による身体の状態の推定処理については、身体の状態を推定するために使用するパラメータに体温及び血圧値が加わることを除いて、図７で説明したものと同様であるため、ここでは説明を省略する。 The estimation process of the body state by the estimation apparatus 200 is the same as that described in FIG. 7 except that the body temperature and the blood pressure value are added to the parameters used for estimating the body state. Description is omitted.
　上述の例では、推定装置２００が体温及び血圧値を測定すると説明したが、推定装置２００による体温及び血圧値の取得は、この方法に限られない。推定装置２００は、例えば、被検者が推定装置２００とは独立した体温計及び血圧計等を用いて測定した値を入力部２３０を用いて入力することにより、体温及び血圧値を取得してもよい。この場合には、推定装置２００は、必ずしも体温測定部２６０及び血圧測定部２７０を備えていなくてもよい。 In the above-described example, it has been described that the estimation device 200 measures the body temperature and the blood pressure value. However, the acquisition of the body temperature and the blood pressure value by the estimation device 200 is not limited to this method. The estimation apparatus 200 may acquire the body temperature and the blood pressure value by, for example, inputting a value measured by the subject using a thermometer and a sphygmomanometer independent of the estimation apparatus 200 using the input unit 230. Good. In this case, the estimation apparatus 200 may not necessarily include the body temperature measurement unit 260 and the blood pressure measurement unit 270.
　推定装置２００は、体温測定部２６０及び血圧測定部２７０の少なくとも一方を備えていなくてもよい。推定装置２００は体温測定部２６０及び血圧測定部２７０以外の、他の生体情報を測定する他の測定部を備えていてもよい。この場合、推定装置２００は、当該他の測定部により測定された他の生体情報に基づいて、身体の状態を推定してもよい。 The estimation apparatus 200 may not include at least one of the body temperature measurement unit 260 and the blood pressure measurement unit 270. The estimation apparatus 200 may include other measurement units that measure other biological information other than the body temperature measurement unit 260 and the blood pressure measurement unit 270. In this case, the estimation apparatus 200 may estimate the state of the body based on other biological information measured by the other measurement unit.
　第２実施形態に係る推定装置２００によれば、第１実施形態と同様に、血管の性質の影響を受けにくい値を用いて、被検者の身体の状態を推定するため、身体の状態の推定精度を向上可能である。第２実施形態に係る推定装置２００によれば、ＳＶに関する値、ＨＲ、体温及び血圧値の総合的な比較に基づいて、身体の状態を推定するため、推定精度がさらに向上する。 According to the estimation apparatus 200 according to the second embodiment, as in the first embodiment, since the state of the subject's body is estimated using values that are not easily affected by the properties of the blood vessels, The estimation accuracy can be improved. According to the estimation apparatus 200 according to the second embodiment, since the body state is estimated based on a comprehensive comparison of the SV-related value, HR, body temperature, and blood pressure value, the estimation accuracy is further improved.

　推定装置３００は、例えば図１で説明したものと同様の外観形状で構成される。推定装置３００は、生体センサ２１０と、制御部２２０と、入力部２３０と、報知部２４０と、記憶部２５０と、通信部２８０とを備える。生体センサ２１０、制御部２２０、入力部２３０、報知部２４０及び記憶部２５０の各機能については、第１実施形態で説明したものと同様であるため、ここでは説明を省略する。 The estimation apparatus 300 is configured with the same external shape as that described in FIG. The estimation apparatus 300 includes a biological sensor 210, a control unit 220, an input unit 230, a notification unit 240, a storage unit 250, and a communication unit 280. The functions of the biosensor 210, the control unit 220, the input unit 230, the notification unit 240, and the storage unit 250 are the same as those described in the first embodiment, and thus description thereof is omitted here.
　通信部２８０は、マッサージ装置４００と有線通信若しくは無線通信又は有線通信及び無線通信の組み合わせの通信を行うことにより、各種情報の送受信を行う。例えば、通信部２８０は、推定装置３００が推定した被検者の身体の状態又は推定装置３００が判定したマッサージの効果等に関する情報をマッサージ装置４００に送信する。 The communication unit 280 transmits and receives various types of information by performing communication with the massage device 400 by wired communication or wireless communication or a combination of wired communication and wireless communication. For example, the communication unit 280 transmits information related to the state of the subject's body estimated by the estimation device 300 or the massage effect determined by the estimation device 300 to the massage device 400.

For example, the communication unit 440 receives, from the estimation device 300, information related to the body state of the subject estimated by the estimation device 300 or the massage effect determined by the estimation device 300.
　次に、図１１を参照しながら、マッサージシステム５００による制御手順の一例について説明する。被検者は、推定装置３００とマッサージ装置４００とを装着して、推定装置３００による測定処理を開始するための所定の操作入力を行う。図１１に示すシーケンスは、当該所定の操作入力を行うと開始される。 Next, an example of a control procedure by the massage system 500 will be described with reference to FIG. The subject wears the estimation device 300 and the massage device 400 and performs a predetermined operation input for starting the measurement process by the estimation device 300. The sequence shown in FIG. 11 is started when the predetermined operation input is performed.
　まず、推定装置３００は、基底血流量を測定し（ステップＳ２０１）、測定した基底血流量に基づいて、ＳＶに関する値及びＨＲを算出する（ステップＳ２０２）。ステップＳ２０１及びステップＳ２０２の詳細は、それぞれ図７のステップＳ１０１及びＳ１０２と同様であるため、ここでは説明を省略する。 First, the estimating apparatus 300 measures the basal blood flow (step S201), and calculates a value and HR related to SV based on the measured basal blood flow (step S202). Details of step S201 and step S202 are the same as steps S101 and S102 of FIG. 7, respectively, and thus description thereof is omitted here.
　推定装置３００は、ＳＶに関する値及びＨＲを算出すると、マッサージ装置４００にマッサージを開始させる指示を送信する（ステップＳ２０３）。 The estimation device 300, after calculating the SV value and HR, transmits an instruction to start the massage to the massage device 400 (step S203).
　マッサージ装置４００は、マッサージを開始させる指示に基づき、マッサージ部４１０による被検者へのマッサージを開始する（ステップＳ２０４）。 The massage device 400 starts massage to the subject by the massage unit 410 based on an instruction to start massage (step S204).
　被検者は、推定装置３００がステップＳ２０２においてＳＶに関する値及びＨＲを算出した後、ステップＳ２０３及びステップＳ２０４によらずに、マッサージを開始するための操作入力を自ら行ってもよい。 The subject may perform the operation input for starting the massage by himself / herself, instead of step S203 and step S204, after the estimation apparatus 300 calculates the SV value and HR in step S202.
　推定装置３００は、マッサージ装置４００によるマッサージ中に、血流量を測定する（ステップＳ２０５）。推定装置３００は、ステップＳ２０５で測定した血流量に基づき、ＳＶに関する値及びＨＲを算出する（ステップＳ２０６）。そして、推定装置３００は、ステップＳ２０６で算出したＳＶに関する値及びＨＲに基づき、身体の状態を推定し（ステップＳ２０７）、推定した身体の状態に基づき、マッサージの効果を判定する（ステップＳ２０８）。ステップＳ２０５からステップＳ２０８の詳細は、それぞれ図７のステップＳ１０３からステップＳ１０６と同様であるため、ここでは説明を省略する。 The estimation apparatus 300 measures the blood flow during the massage by the massage apparatus 400 (step S205). The estimation apparatus 300 calculates a value related to SV and HR based on the blood flow measured in step S205 (step S206). Then, the estimation apparatus 300 estimates the body state based on the SV-related value and HR calculated in step S206 (step S207), and determines the massage effect based on the estimated body state (step S208). Details of step S205 to step S208 are the same as step S103 to step S106 of FIG.
　推定装置３００は、ステップＳ２０８で判定したマッサージの効果をマッサージ装置４００に通知する（ステップＳ２０９）。 The estimating apparatus 300 notifies the massage apparatus 400 of the effect of the massage determined in step S208 (step S209).
　マッサージ装置４００は、推定装置３００からマッサージの効果に関する情報を取得すると、取得したマッサージの効果に応じた制御を実行する（ステップＳ２１０）。 The massage apparatus 400, when acquiring information related to the massage effect from the estimation apparatus 300, executes control according to the acquired massage effect (step S210).
　推定装置３００は、ステップＳ２０９において、マッサージの効果に代えて、ステップＳ２０７で推定した身体の状態に関する情報をマッサージ装置４００に送信してもよい。この場合、マッサージ装置４００は、取得した身体の状態に関する情報に基づき、推定装置３００によるステップＳ２０８と同様の要領で、マッサージの効果を判定してもよい。 In step S209, the estimation apparatus 300 may transmit information on the body state estimated in step S207 to the massage apparatus 400 in place of the massage effect. In this case, the massage device 400 may determine the effect of the massage in the same manner as Step S208 by the estimation device 300 based on the acquired information on the body state.
　推定装置３００は、被検者がマッサージを受けている間、ステップＳ２０５からステップＳ２０９を繰り返して実行してもよい。 The estimation apparatus 300 may repeatedly execute Step S205 to Step S209 while the subject is receiving massage.
　図１２は、マッサージ装置４００によるマッサージの処理の一例を示すフローチャートである。図１２は、図１１のステップＳ２１０の詳細を示すフローチャートである。 FIG. 12 is a flowchart showing an example of massage processing by the massage apparatus 400. FIG. 12 is a flowchart showing details of step S210 in FIG.
　マッサージ装置４００は、図１１のステップＳ２０９で推定装置３００から取得したマッサージの効果に関する情報が、マッサージの効果がある又はマッサージの効果が高いことを示す情報であるか否かを判定する（ステップＳ３０１）。 The massage apparatus 400 determines whether or not the information regarding the massage effect acquired from the estimation apparatus 300 in step S209 of FIG. 11 is information indicating that there is a massage effect or a high massage effect (step S301). ).
　マッサージ装置４００は、推定装置３００から取得したマッサージの効果に関する情報が、マッサージの効果がある又はマッサージの効果が高いことを示す情報である場合（ステップＳ３０１のＹｅｓ）、マッサージ部４１０による同一内容のマッサージを継続する。同一内容のマッサージを継続することにより、被検者の身体にさらなるリラックス効果をもたらすことが期待されるためである。 When the information regarding the massage effect acquired from the estimation device 300 is information indicating that there is a massage effect or a high massage effect (Yes in step S301), the massage device 400 has the same content by the massage unit 410. Continue the massage. This is because it is expected that the body of the subject is further relaxed by continuing the massage with the same content.
　マッサージ装置４００は、推定装置３００から取得したマッサージの効果に関する情報が、マッサージの効果がない又はマッサージの効果が低いことを示す情報である場合（ステップＳ３０１のＮｏ）、マッサージを開始してから、マッサージの押圧パターンを変更したか否かを判断する（ステップＳ３０２）。 When the massage apparatus 400 is information indicating that the massage effect acquired from the estimation apparatus 300 is not effective or the massage effect is low (No in step S301), the massage apparatus 400 starts the massage, It is determined whether or not the massage pressing pattern has been changed (step S302).
　マッサージ装置４００は、マッサージを開始してから、マッサージの押圧パターンを変更していないと判断した場合（ステップＳ３０２のＮｏ）、押圧パターンを変更する（ステップＳ３０３）。このように、被検者に対して行っているマッサージの効果がない又は効果が低い場合、マッサージ装置４００は、変更した押圧パターンでマッサージを行うことができる。 When the massage apparatus 400 determines that the massage pressing pattern has not been changed since the massage was started (No in step S302), the massage device 400 changes the pressing pattern (step S303). Thus, when there is no effect of the massage currently performed with respect to a subject, or the effect is low, the massage apparatus 400 can massage with the changed press pattern.
　一方、マッサージ装置４００は、マッサージを開始してから、マッサージの押圧パターンを変更したと判断した場合（ステップＳ３０２のＹｅｓ）、マッサージを停止する（ステップＳ３０４）。マッサージ装置４００がマッサージの押圧パターンを変更したと判断するのは、マッサージを開始してから少なくとも一度、マッサージの効果がない又は効果が低いと判断して、押圧パターンを変更した場合である。つまり、マッサージ装置４００は、マッサージ開始後の押圧パターンと、一度変更した押圧パターンとの２種類の押圧パターンによっても、マッサージの効果がない又は効果が低い場合に、マッサージを停止する。このように２種類の押圧パターンのいずれでも、マッサージの効果がない又は効果が低い場合には、マッサージ装置４００は、効果的なマッサージを行うことが困難であると判断して、自動的にマッサージを停止することができる。 On the other hand, when the massage apparatus 400 determines that the massage pressing pattern has been changed after starting the massage (Yes in step S302), the massage apparatus 400 stops the massage (step S304). The massage device 400 determines that the massage pressing pattern has been changed when it has been determined that the massage has no effect or is less effective at least once after the massage is started, and the pressing pattern has been changed. That is, the massage device 400 stops the massage when there is no massage effect or the effect is low even with the two types of press patterns of the press pattern after the start of the massage and the press pattern that has been changed once. As described above, in any of the two types of pressing patterns, when the effect of massage is not effective or low, the massage device 400 determines that it is difficult to perform effective massage, and automatically massages. Can be stopped.
　マッサージ装置４００は、推定装置３００から取得したマッサージの効果に関する情報が、マッサージの効果がない又はマッサージの効果が低いことを示す情報である場合（ステップＳ３０１のＮｏ）、ステップＳ３０２による判断を行うことなく、自動的にステップＳ３０３に移行して押圧パターンを変更してもよい。この場合、マッサージ装置４００は、マッサージの効果がある又は効果が高いと判定されるまで、押圧パターンを変更し続ける。 The massage apparatus 400 performs the determination by step S302, when the information regarding the effect of the massage acquired from the estimation apparatus 300 is information indicating that there is no massage effect or the massage effect is low (No in step S301). Instead, the process may automatically shift to step S303 to change the pressing pattern. In this case, the massage apparatus 400 continues to change the pressing pattern until it is determined that there is a massage effect or a high effect.
　このように、第３実施形態に係るマッサージシステム５００によれば、第１実施形態と同様に、血管の性質の影響を受けにくい値を用いて、被検者の身体の状態を推定するため、身体の状態の推定精度を向上可能である。第３実施形態に係るマッサージシステム５００によれば、被検者の身体の状態又はマッサージの効果に基づいて、自動的にマッサージの内容（押圧パターン）を変更することができる。 Thus, according to the massage system 500 according to the third embodiment, in order to estimate the state of the body of the subject using values that are not easily affected by the properties of blood vessels, as in the first embodiment, The estimation accuracy of the body state can be improved. According to the massage system 500 according to the third embodiment, the content (pressing pattern) of the massage can be automatically changed based on the state of the body of the subject or the effect of the massage.
　第３実施形態に係る推定装置３００は、第２実施形態で説明した推定装置２００のように、ＳＶに関する値、ＨＲ、体温及び血圧値のうちの少なくともいずれかに基づいて身体の状態を推定してもよい。 The estimation apparatus 300 according to the third embodiment estimates the state of the body based on at least one of the SV-related value, HR, body temperature, and blood pressure value, like the estimation apparatus 200 described in the second embodiment. May be.
　マッサージシステム５００は、推定装置３００及びマッサージ装置４００と通信可能な端末装置をさらに有していてもよい。マッサージシステム５００は、例えば図１３に変形例として示すように、推定装置３００と、マッサージ装置４００と、端末装置６００とを有していてもよい。端末装置６００は、推定装置３００が備える上述の機能の一部を有していてもよい。 The massage system 500 may further include a terminal device that can communicate with the estimation device 300 and the massage device 400. The massage system 500 may include an estimation device 300, a massage device 400, and a terminal device 600, for example, as shown in FIG. The terminal device 600 may have a part of the above-described functions included in the estimation device 300.
　端末装置６００は、推定装置３００及びマッサージ装置４００とそれぞれ通信可能である。図１３に示す変形例では、例えば推定装置３００は、被検者がマッサージ装置４００によるマッサージを受けている間に、被検者に装着された状態で、生体情報として血流量を取得する。推定装置３００は、取得した血流量を端末装置６００に送信する。端末装置６００は、取得した血流量に基づいて、ＳＶに関する値及びＨＲを算出する。端末装置６００は、ＳＶに関する値及びＨＲに基づいて、身体の状態を推定する。端末装置６００は、推定した身体の状態に基づいて、マッサージの効果を判定できる。端末装置６００は、判定したマッサージの効果を、自ら備えるディスプレイ等に表示することにより、被検者に報知してもよい。端末装置６００は、判定したマッサージの効果に関する情報をマッサージ装置４００に送信してもよい。マッサージの効果に関する情報を取得したマッサージ装置４００は、例えば図１２に示した、効果に応じた制御を行うことができる。 The terminal device 600 can communicate with the estimation device 300 and the massage device 400, respectively. In the modification shown in FIG. 13, for example, the estimation device 300 acquires the blood flow rate as biological information while the subject is being massaged by the massage device 400 while being worn by the subject. The estimation device 300 transmits the acquired blood flow volume to the terminal device 600. The terminal device 600 calculates a value related to SV and HR based on the acquired blood flow volume. The terminal device 600 estimates the state of the body based on the value related to SV and HR. The terminal device 600 can determine the effect of the massage based on the estimated body state. The terminal device 600 may notify the subject by displaying the determined massage effect on a display or the like provided on the terminal device 600. The terminal device 600 may transmit information regarding the determined massage effect to the massage device 400. The massage apparatus 400 which acquired the information regarding the effect of a massage can perform control according to the effect shown, for example in FIG.
　第３実施形態で説明した各制御は、必ずしも上述の説明で対応付けた装置が実行しなくてもよい。各制御は、例えば上述の説明で対応付けられた装置とは異なる装置が実行してもよい。例えば、図１２において、ステップＳ３０１及びステップＳ３０２は、マッサージ装置４００が実行するとして説明したが、推定装置３００又は端末装置６００により実行されてもよい。ステップＳ３０１及びステップＳ３０２が推定装置３００により実行される場合、推定装置３００は、ステップＳ３０１及びステップＳ３０２の判定結果に応じて、マッサージ装置４００を制御するための信号をマッサージ装置４００に送信してもよい。 Each control described in the third embodiment may not necessarily be executed by the device associated in the above description. Each control may be executed by a device different from the device associated in the above description, for example. For example, in FIG. 12, step S301 and step S302 have been described as being executed by the massage device 400, but may be executed by the estimation device 300 or the terminal device 600. When steps S301 and S302 are executed by the estimation device 300, the estimation device 300 may transmit a signal for controlling the massage device 400 to the massage device 400 according to the determination results of step S301 and step S302. Good.
（第４実施形態）
　図１４は、本開示の第４実施形態に係るマッサージシステムの概略構成を示す機能ブロック図である。マッサージシステム７００は、有線又は無線により互いに通信可能に構成された推定装置３００とマッサージ装置４００とを含む。 (Fourth embodiment)
FIG. 14 is a functional block diagram illustrating a schematic configuration of a massage system according to the fourth embodiment of the present disclosure. The massage system 700 includes an estimation device 300 and a massage device 400 configured to be able to communicate with each other by wire or wireless.
　推定装置３００は、例えば図１で説明したものと同様の外観形状で構成される。推定装置３００は、生体センサ２１０と、制御部２２０と、入力部２３０と、報知部２４０と、記憶部２５０と、通信部２８０とを備える。入力部２３０と、報知部２４０と、記憶部２５０と、通信部２８０との各機能については、第３実施形態で説明したものと同様であるため、ここでは説明を省略する。 The estimation apparatus 300 is configured with the same external shape as that described in FIG. The estimation apparatus 300 includes a biological sensor 210, a control unit 220, an input unit 230, a notification unit 240, a storage unit 250, and a communication unit 280. Since the functions of the input unit 230, the notification unit 240, the storage unit 250, and the communication unit 280 are the same as those described in the third embodiment, description thereof is omitted here.
　本実施形態における生体センサ２１０は、発光部２１１と、受光部２１２と、加速度センサ２１３とを備える。発光部２１１及び受光部２１２の各機能は、第３実施形態で説明したものと同様であるため、ここでは説明を省略する。加速度センサ２１３は、生体センサ２１０に作用する加速度の大きさ（以下「加速度情報」とも称する）を検出する。加速度センサ２１３は、検出した加速度情報を制御部２２０に出力する。 The biosensor 210 in this embodiment includes a light emitting unit 211, a light receiving unit 212, and an acceleration sensor 213. Since the functions of the light emitting unit 211 and the light receiving unit 212 are the same as those described in the third embodiment, description thereof is omitted here. The acceleration sensor 213 detects the magnitude of acceleration acting on the biosensor 210 (hereinafter also referred to as “acceleration information”). The acceleration sensor 213 outputs the detected acceleration information to the control unit 220.
　制御部２２０は、第３実施形態で説明したのと同様にマッサージの効果を判定する。本実施形態における制御部２２０は、さらに、加速度センサ２１３から出力された加速度情報に基づいて、判定したマッサージの効果の信頼度を算出する。マッサージの効果の信頼度は、判定したマッサージの効果に関する情報が信用できるか否かに関する指標である。制御部２２０は、算出した信頼度を、報知部２４０から報知してよい。 Control unit 220 determines the effect of massage in the same manner as described in the third embodiment. The controller 220 in the present embodiment further calculates the reliability of the determined massage effect based on the acceleration information output from the acceleration sensor 213. The reliability of the massage effect is an index relating to whether or not the information related to the determined massage effect can be trusted. The control unit 220 may notify the calculated reliability from the notification unit 240.
　マッサージ装置４００の構成は、第３実施形態で説明したものと同様である。本実施形態におけるマッサージ装置４００は、推定装置３００が算出した信頼度に応じたマッサージの押圧パターンの変更を行ってもよい。例えば、マッサージ装置４００は、信頼度が所定の閾値よりも低い場合には、マッサージの効果によらず、同じ押圧パターンでマッサージを行ってもよい。マッサージ装置４００は、信頼度が所定の閾値以上の場合に、マッサージの効果に応じて押圧パターンを変更してもよい。 The configuration of the massage device 400 is the same as that described in the third embodiment. The massage device 400 in the present embodiment may change the massage pressing pattern according to the reliability calculated by the estimation device 300. For example, when the reliability is lower than a predetermined threshold, the massage device 400 may perform massage with the same pressing pattern regardless of the massage effect. The massage device 400 may change the pressing pattern according to the massage effect when the reliability is equal to or higher than a predetermined threshold.
　ここで、マッサージの効果の信頼度について説明する。推定装置３００は、被検者に装着された状態において、装着状態がずれる（変位する）場合がある。推定装置３００の装着状態がずれることにより、生体センサ２１０と被検部位との位置関係が変化する。これにより、受光部２１２が受光する散乱光の強度が変化し得る。その結果、ＳＶに関する値の算出結果に誤差が生じる場合がある。本実施形態における制御部２２０は、加速度センサ２１３の出力に基づいて、ＳＶに関する値の算出結果の誤差の程度を判断して、マッサージの効果の信頼度を算出する。 Here, the reliability of the massage effect will be explained. When the estimation device 300 is worn on the subject, the wearing state may shift (displace). When the wearing state of the estimation apparatus 300 is shifted, the positional relationship between the biological sensor 210 and the test site changes. Thereby, the intensity | strength of the scattered light which the light-receiving part 212 light-receives can change. As a result, an error may occur in the calculation result of the value related to SV. Based on the output of the acceleration sensor 213, the control unit 220 in the present embodiment determines the degree of error in the calculation result of the value related to SV, and calculates the reliability of the massage effect.
　具体的には、制御部２２０は、加速度情報に基づいて算出される値と、生体情報に基づいて算出される値との相関（相関係数）を算出する。加速度情報に基づいて算出される値として、例えば加速度情報に基づいて算出される加速度の標準偏差が用いられる。生体情報に基づく値として、ＳＶに関する値又はＨＲの少なくともいずれかの標準偏差が用いられる。すなわち、制御部２２０は、加速度情報に基づいて算出される加速度の標準偏差と、ＳＶに関する値又はＨＲの標準偏差との相関係数を算出する。そして、制御部２２０は、ＳＶに関する値又はＨＲの相関係数に基づいてマッサージの効果の信頼度を算出する。本開示では、生体情報に基づく値がＳＶに関する値であるとして説明する。以下の説明では、加速度の標準偏差とＳＶに関する値の標準偏差との相関係数を求めているが、速度とＳＶに関する値との相関係数を求めて、このＳＶに関する値の指標が、生体センサの変位の影響を受けにくい指標であると判断しても良い。ここで、本開示において、ｘとｙとの相関係数とは、ｘとｙとの共分散を、ｘの標準偏差とｙの標準偏差で割ったものである。ｘとｙとの共分散とは、ｘの偏差とｙの偏差の積の平均値である。 Specifically, the control unit 220 calculates a correlation (correlation coefficient) between a value calculated based on the acceleration information and a value calculated based on the biological information. As a value calculated based on the acceleration information, for example, a standard deviation of acceleration calculated based on the acceleration information is used. As a value based on biometric information, a value related to SV or a standard deviation of at least one of HR is used. That is, the control unit 220 calculates a correlation coefficient between the standard deviation of acceleration calculated based on the acceleration information and the value related to SV or the standard deviation of HR. And the control part 220 calculates the reliability of the effect of a massage based on the value regarding SV, or the correlation coefficient of HR. In the present disclosure, a value based on biological information is described as a value related to SV. In the following description, the correlation coefficient between the standard deviation of acceleration and the standard deviation of the value related to SV is obtained. However, the correlation coefficient between the speed and the value related to SV is obtained and It may be determined that the index is not easily affected by the sensor displacement. Here, in the present disclosure, the correlation coefficient between x and y is obtained by dividing the covariance between x and y by the standard deviation of x and the standard deviation of y. The covariance between x and y is an average value of products of x deviation and y deviation.
　図１５Ａ及び図１５Ｂは、加速度の標準偏差と、ＳＶに関する値の標準偏差との関係について説明する図である。図１５Ａ及び図１５Ｂでは、ＳＶに関する値の一例として、血流量と脈動血流波高とが示されている。すなわち、図１５Ａ及び図１５Ｂは、推定装置の加速度の標準偏差と、血流量及び脈動血流波高の標準偏差との関係を示す。図１５Ａ及び図１５Ｂにおいて、横軸は加速度の標準偏差を示し、縦軸は血流量又は脈動血流波高の標準偏差を示す。 15A and 15B are diagrams illustrating the relationship between the standard deviation of acceleration and the standard deviation of values related to SV. In FIG. 15A and FIG. 15B, the blood flow volume and the pulsating blood flow wave height are shown as examples of values related to SV. That is, FIG. 15A and FIG. 15B show the relationship between the standard deviation of the acceleration of the estimation device and the standard deviation of the blood flow volume and the pulsating blood flow wave height. 15A and 15B, the horizontal axis indicates the standard deviation of acceleration, and the vertical axis indicates the standard deviation of blood flow volume or pulsating blood flow wave height.
　図１５Ａは、加速度の標準偏差と、血流量及び脈動血流波高の標準偏差との相関が高い場合の例を示す。図１５Ａに示す例において、加速度の標準偏差と、血流量の標準偏差との相関係数は、０．７９である。図１５Ａに示す例において、加速度の標準偏差と、脈動血流波高の標準偏差との相関係数は、０．８５である。 FIG. 15A shows an example in which the standard deviation of acceleration is highly correlated with the standard deviation of blood flow volume and pulsating blood flow wave height. In the example shown in FIG. 15A, the correlation coefficient between the standard deviation of acceleration and the standard deviation of blood flow is 0.79. In the example shown in FIG. 15A, the correlation coefficient between the standard deviation of acceleration and the standard deviation of pulsating blood flow wave height is 0.85.
　図１５Ｂは、加速度の標準偏差と、血流量及び脈動血流波高の標準偏差との相関が低い場合の例を示す。図１５Ｂに示す例において、加速度の標準偏差と、血流量の標準偏差との相関係数は、０．１２である。図１５Ｂに示す例において、加速度の標準偏差と、脈動血流波高の標準偏差との相関係数は、０．０６である。 FIG. 15B shows an example in which the correlation between the standard deviation of acceleration and the standard deviation of blood flow volume and pulsating blood flow wave height is low. In the example shown in FIG. 15B, the correlation coefficient between the standard deviation of acceleration and the standard deviation of blood flow is 0.12. In the example shown in FIG. 15B, the correlation coefficient between the standard deviation of acceleration and the standard deviation of pulsating blood flow wave height is 0.06.
　加速度センサ２１３により取得される加速度は、生体センサ２１０の変位が反映された値である。そのため、加速度の標準偏差とＳＶに関する値の標準偏差との相関係数が小さいほど、ＳＶに関する値は、加速度の影響を受けていないといえる。すなわち、相関係数が小さい程、生体センサ２１０は、変位による影響を受けていない、信頼度の高い生体情報を取得できているといえる。制御部２２０は、加速度の標準偏差と、マッサージの効果の判定のために使用されるＳＶに関する値の標準偏差との相関係数に基づいて、マッサージの効果の信頼度を算出する。例えば、制御部２２０は、加速度の標準偏差と、マッサージの効果の判定のために使用されるＳＶに関する値の標準偏差との相関係数の逆数を、そのマッサージの効果の信頼度としてもよいし、その他この相関係数に適宜重みづけの演算を行ってマッサージの効果の信頼度としてもよい。 The acceleration acquired by the acceleration sensor 213 is a value reflecting the displacement of the biological sensor 210. Therefore, it can be said that the smaller the correlation coefficient between the standard deviation of acceleration and the standard deviation of the value related to SV, the less the value related to SV is affected by the acceleration. In other words, it can be said that the smaller the correlation coefficient, the more biometric sensor 210 can acquire biometric information that is not affected by displacement and has high reliability. The control unit 220 calculates the reliability of the massage effect based on the correlation coefficient between the standard deviation of the acceleration and the standard deviation of the value related to the SV used for the determination of the massage effect. For example, the control unit 220 may use the reciprocal of the correlation coefficient between the standard deviation of acceleration and the standard deviation of the SV-related value used for determining the massage effect as the reliability of the massage effect. In addition, it is good also as the reliability of the effect of a massage by calculating | requiring weighting suitably to this correlation coefficient.
　次に、図１６を参照しながら、マッサージシステム７００による制御手順の一例について説明する。被検者は、推定装置３００とマッサージ装置４００とを装着して、推定装置３００による測定処理を開始するための所定の操作入力を行う。図１６に示すシーケンスは、当該所定の操作入力を行うと開始される。 Next, an example of a control procedure by the massage system 700 will be described with reference to FIG. The subject wears the estimation device 300 and the massage device 400 and performs a predetermined operation input for starting the measurement process by the estimation device 300. The sequence shown in FIG. 16 is started when the predetermined operation input is performed.
　まず、推定装置３００は、基底血流量を測定し（ステップＳ４０１）、測定した基底血流量に基づいて、ＳＶに関する値及びＨＲを算出する（ステップＳ４０２）。推定装置３００は、マッサージを開始させる指示をマッサージ装置４００に送信する（ステップＳ４０３）。マッサージ装置４００は、マッサージを開始させる指示に基づき、マッサージ部４１０による被検者へのマッサージを開始する（ステップＳ４０４）。推定装置３００は、マッサージ装置４００によるマッサージ中に、血流量を測定する（ステップＳ４０５）。ステップＳ４０１からステップＳ４０５の詳細は、それぞれ図１１のステップＳ２０１からステップＳ２０５と同様である。 First, the estimation apparatus 300 measures the basal blood flow (step S401), and calculates a value and HR related to SV based on the measured basal blood flow (step S402). The estimation apparatus 300 transmits an instruction to start massage to the massage apparatus 400 (step S403). The massage device 400 starts massage to the subject by the massage unit 410 based on an instruction to start massage (step S404). The estimation apparatus 300 measures the blood flow during the massage by the massage apparatus 400 (step S405). Details of steps S401 to S405 are the same as steps S201 to S205 of FIG. 11, respectively.
　推定装置３００は、加速度センサ２１３において、マッサージ中における生体センサ２１０の加速度情報を取得する（ステップＳ４０６）。推定装置３００は、マッサージを行っている間、例えば継続的にステップＳ４０５及びステップＳ４０６を繰り返すことにより、血流量の測定と加速度情報の取得を行う。推定装置３００は、血流量の測定と加速度情報の取得の双方、又は一方を、所定の時間間隔で断続的に行うとしても良い。この場合、血流量の測定と加速度情報の取得のための消費電力が削減される。 The estimation apparatus 300 acquires acceleration information of the living body sensor 210 during massage in the acceleration sensor 213 (step S406). The estimation apparatus 300 measures blood flow and acquires acceleration information by repeating step S405 and step S406 continuously, for example, while performing massage. The estimation apparatus 300 may intermittently perform both or one of blood flow measurement and acceleration information acquisition at predetermined time intervals. In this case, power consumption for blood flow measurement and acceleration information acquisition is reduced.
　推定装置３００は、ステップＳ４０５で測定した血流量に基づき、ＳＶに関する値及びＨＲを算出する（ステップＳ４０７）。そして、推定装置３００は、ステップＳ４０７で算出したＳＶに関する値及びＨＲに基づき、身体の状態を推定し（ステップＳ４０８）、推定した身体の状態に基づき、マッサージの効果を判定する（ステップＳ４０９）。ステップＳ４０７からステップＳ４０９は、それぞれ図１１のステップＳ２０６からステップＳ２０８と同様である。 The estimation apparatus 300 calculates a value related to SV and HR based on the blood flow measured in step S405 (step S407). Then, the estimation apparatus 300 estimates the body state based on the SV-related value and HR calculated in step S407 (step S408), and determines the massage effect based on the estimated body state (step S409). Steps S407 to S409 are the same as steps S206 to S208 in FIG. 11, respectively.
　推定装置３００は、ステップＳ４０９において判定したマッサージの効果を、報知部２４０から報知する（ステップＳ４１０）。 The estimation apparatus 300 notifies the effect of the massage determined in step S409 from the notification unit 240 (step S410).
　推定装置３００は、マッサージ中に測定した血流量に基づいて算出されるＳＶに関する値に基づいて、ＳＶに関する値の標準偏差を算出する。推定装置３００は、マッサージ中に取得した加速度情報に基づいて、加速度の標準偏差を算出する（ステップＳ４１１）。 The estimation device 300 calculates the standard deviation of the value related to SV based on the value related to SV calculated based on the blood flow measured during the massage. The estimation apparatus 300 calculates a standard deviation of acceleration based on the acceleration information acquired during the massage (step S411).
　推定装置３００は、ステップＳ４１１で算出したＳＶに関する値の標準偏差と、加速度の標準偏差との相関係数を算出する（ステップＳ４１２）。 The estimation apparatus 300 calculates a correlation coefficient between the standard deviation of the SV-related value calculated in step S411 and the standard deviation of acceleration (step S412).
　推定装置３００は、ステップＳ４１２で算出した相関係数に基づいてマッサージの効果の信頼度を算出する（ステップＳ４１３）。例えば、推定装置３００は、加速度の標準偏差と、マッサージの効果の判定のために使用されるＳＶに関する値の標準偏差との相関係数の逆数を、そのマッサージの効果の信頼度とする。 The estimation apparatus 300 calculates the reliability of the massage effect based on the correlation coefficient calculated in step S412 (step S413). For example, the estimation apparatus 300 uses the reciprocal of the correlation coefficient between the standard deviation of acceleration and the standard deviation of the value related to SV used for determining the massage effect as the reliability of the massage effect.
　推定装置３００は、ステップＳ４１３で算出したマッサージの効果の信頼度に関する情報を、報知部２４０から報知する（ステップＳ４１４）。推定装置３００は、例えば、数値として、マッサージの効果の信頼度に関する情報を報知してよい。推定装置３００は、例えば高、中及び低等のように、複数の区分によりマッサージの効果の信頼度に関する情報を報知してもよい。推定装置３００は、例えば赤、黄及び青等のように、複数の色によりマッサージの効果の信頼度に関する情報を報知してもよい。推定装置３００は、例えば複数の振動の強弱及びパターンを組み合わせて振動の変化によりマッサージの効果の信頼度に関する情報を報知してもよい。推定装置３００は、例えば丸、三角及び四角等のように、複数の図形によりマッサージの効果の信頼度に関する情報を報知してもよい。推定装置３００は、例えば音声メッセージによりマッサージの効果の信頼度に関する情報を報知してもよい。推定装置３００は、例えば音によりマッサージの効果の信頼度に関する情報を報知してもよい。推定装置３００は、例えば複数の画像により信頼度に関する情報を報知してもよい。推定装置３００は、上記の、数値、複数の区分、色、振動の変化、図形、音声メッセージ、音及び画像等を任意に組み合わせてマッサージの効果の信頼度に関する情報を報知してもよい。推定装置３００が信頼度に関する情報を報知するとしたが、推定装置３００に代えて、又は、推定装置３００と共に、マッサージ装置４００がこの情報を報知してもよい。 The estimation apparatus 300 notifies the information about the reliability of the massage effect calculated in step S413 from the notification unit 240 (step S414). The estimation apparatus 300 may notify information related to the reliability of the massage effect, for example, as a numerical value. The estimation apparatus 300 may notify information related to the reliability of the massage effect by a plurality of sections, such as high, medium, and low. The estimation apparatus 300 may notify information related to the reliability of the massage effect using a plurality of colors, such as red, yellow, and blue. The estimation apparatus 300 may notify information related to the reliability of the massage effect by a change in vibration by combining a plurality of vibration strengths and patterns, for example. The estimation apparatus 300 may notify information related to the reliability of the massage effect using a plurality of figures, such as a circle, a triangle, and a square. The estimation apparatus 300 may notify information related to the reliability of the massage effect by, for example, a voice message. The estimation apparatus 300 may notify information related to the reliability of the massage effect using sound, for example. For example, the estimation apparatus 300 may notify information related to reliability using a plurality of images. The estimation apparatus 300 may notify information related to the reliability of the massage effect by arbitrarily combining the above-described numerical values, a plurality of categories, colors, vibration changes, graphics, voice messages, sounds, images, and the like. Although the estimation apparatus 300 reports the information on the reliability, the massage apparatus 400 may notify this information instead of the estimation apparatus 300 or together with the estimation apparatus 300.
　推定装置３００は、ステップＳ４０９で判定したマッサージの効果をマッサージ装置４００に通知する（ステップＳ４１５）。 The estimation apparatus 300 notifies the massage apparatus 400 of the effect of the massage determined in step S409 (step S415).
　推定装置３００は、ステップＳ４１３で算出したマッサージの効果の信頼度を、マッサージ装置４００に通知する（ステップＳ４１６）。 The estimation apparatus 300 notifies the massage apparatus 400 of the reliability of the massage effect calculated in step S413 (step S416).
　マッサージ装置４００は、推定装置３００からマッサージの効果に関する情報及び効果の信頼度に関する情報を取得すると、取得した信頼度及び効果に応じた制御を実行する（ステップＳ４１７）。 The massage apparatus 400, when acquiring information related to the effect of massage and information related to the reliability of the effect from the estimation apparatus 300, executes control according to the acquired reliability and effect (step S417).
　図１７は、マッサージ装置４００によるマッサージの処理の一例を示すフローチャートである。図１７は、図１６のステップＳ４１７の詳細を示すフローチャートである。 FIG. 17 is a flowchart showing an example of massage processing by the massage apparatus 400. FIG. 17 is a flowchart showing details of step S417 in FIG.
　マッサージ装置４００は、図１６のステップＳ４１６で取得したマッサージの効果の信頼度が、所定の閾値以上であるか否かを判定する（ステップＳ５０１）。 The massage apparatus 400 determines whether or not the reliability of the massage effect acquired in step S416 in FIG. 16 is equal to or higher than a predetermined threshold (step S501).
　マッサージ装置４００は、マッサージの効果の信頼度が所定の閾値未満であると判定した場合（ステップＳ５０１のＮｏ）、取得したマッサージの効果が正確でない可能性があると判断して、押圧パターンを変更することなく、このフローを終了する。 When the massage device 400 determines that the reliability of the massage effect is less than the predetermined threshold (No in step S501), the massage device 400 determines that the acquired massage effect may not be accurate, and changes the pressing pattern. This flow is finished without doing.
　一方、マッサージ装置４００は、マッサージの効果の信頼度が所定の閾値以上であると判定した場合（ステップＳ５０１のＹｅｓ）、図１６のステップＳ４１５で推定装置３００から取得したマッサージの効果に関する情報が、マッサージの効果がある又はマッサージの効果が高いことを示す情報であるか否かを判定する（ステップＳ５０２）。このように、マッサージ装置４００は、取得したマッサージの効果の信頼度が所定の閾値以上の場合に、マッサージの効果に基づいた制御を行う。 On the other hand, when the massage device 400 determines that the reliability of the massage effect is equal to or higher than the predetermined threshold (Yes in step S501), information on the massage effect acquired from the estimation device 300 in step S415 in FIG. It is determined whether or not the information indicates that there is a massage effect or a high massage effect (step S502). Thus, the massage apparatus 400 performs control based on the massage effect when the reliability of the acquired massage effect is equal to or greater than a predetermined threshold.
　マッサージ装置４００は、以降、図１２で示したのと同様の制御を行う。すなわち、ステップＳ５０２からステップＳ５０５は、それぞれ図１２のステップＳ３０１からステップＳ３０４と同様である。ここでは、ステップＳ５０２からステップＳ５０５についての詳細な説明を省略する。 The massage apparatus 400 performs the same control as shown in FIG. That is, steps S502 to S505 are the same as steps S301 to S304 in FIG. 12, respectively. Here, detailed description of steps S502 to S505 is omitted.
　このように、第４実施形態に係るマッサージシステム７００によれば、第１実施形態と同様に、血管の性質の影響を受けにくい値を用いて、被検者の身体の状態を推定するため、身体の状態の推定精度を向上可能である。第４実施形態に係るマッサージシステム７００によれば、被検者の身体の状態又はマッサージの効果に基づいて、自動的にマッサージの内容（押圧パターン）を変更することができる。 Thus, according to the massage system 700 according to the fourth embodiment, in order to estimate the state of the subject's body using values that are not easily affected by the properties of blood vessels, as in the first embodiment, The estimation accuracy of the body state can be improved. According to the massage system 700 according to the fourth embodiment, the content (pressing pattern) of the massage can be automatically changed based on the state of the body of the subject or the effect of the massage.
　第４実施形態に係るマッサージシステム７００によれば、推定装置３００が、生体情報に基づく値と、加速度情報に基づく値との相関を算出する。相関により、生体情報の信頼度が導出できるため、推定装置３００は、生体情報の測定精度を検出できる。すなわち、第４実施形態に係るマッサージシステム７００によれば、推定装置３００が、生体情報に基づく値と、加速度情報に基づく値との相関を算出することにより、生体情報に基づく値がどのくらい加速度と関連しているかを判定することができる。生体情報に基づく値と加速度との関連が小さければ、この生体情報は推定装置の動きに対して耐久力のある情報であると考えられる。つまり、生体情報に基づく値と加速度との関連が小さい生体情報は推定装置の動きノイズに対して影響を受けにくい値であると考えられる。 According to the massage system 700 according to the fourth embodiment, the estimation device 300 calculates the correlation between the value based on the biological information and the value based on the acceleration information. Since the reliability of the biological information can be derived by the correlation, the estimation apparatus 300 can detect the measurement accuracy of the biological information. In other words, according to the massage system 700 according to the fourth embodiment, the estimation device 300 calculates the correlation between the value based on the biological information and the value based on the acceleration information, so that the acceleration based on the value based on the biological information It can be determined whether they are related. If the relationship between the value based on the biological information and the acceleration is small, the biological information is considered to be information that is durable against the movement of the estimation device. That is, it is considered that the biological information having a small relationship between the value based on the biological information and the acceleration is a value that is not easily affected by the motion noise of the estimation device.
　さらに、第４実施形態に係るマッサージシステム７００によれば、マッサージの効果の信頼度を算出し、報知できる。そのため、被検者は、マッサージの効果の信頼度を知ることができる。第４実施形態に係るマッサージシステム７００によれば、マッサージの効果の信頼度に応じて押圧パターンの制御を行う。例えば、マッサージ装置４００は、信頼度が所定の閾値以上の場合に、マッサージの効果に応じた押圧パターンの制御を行うことにより、より正確な効果に基づいて押圧パターンを制御できる。これにより、マッサージ装置４００は、被検者に対するマッサージの効果に基づいた、より適切なマッサージを提供できる。 Furthermore, according to the massage system 700 according to the fourth embodiment, the reliability of the massage effect can be calculated and notified. Therefore, the subject can know the reliability of the massage effect. According to the massage system 700 according to the fourth embodiment, the pressing pattern is controlled according to the reliability of the massage effect. For example, the massage device 400 can control the press pattern based on a more accurate effect by controlling the press pattern according to the effect of the massage when the reliability is equal to or higher than a predetermined threshold. Thereby, the massage apparatus 400 can provide more appropriate massage based on the effect of the massage with respect to a subject.
　第４実施形態に係る推定装置３００は、第２実施形態で説明した推定装置２００のように、ＳＶに関する値、ＨＲ、体温及び血圧値の少なくともいずれかに基づいて身体の状態を推定してもよい。 The estimation apparatus 300 according to the fourth embodiment estimates the body state based on at least one of the SV-related value, HR, body temperature, and blood pressure value, like the estimation apparatus 200 described in the second embodiment. Good.
　第４実施形態に係るマッサージシステム７００は、図１３で説明したように、推定装置３００及びマッサージ装置４００と通信可能な端末装置をさらに有して構成されていてもよい。この場合、上述のように、端末装置は、推定装置３００が備える機能の一部を有していてもよい。 The massage system 700 according to the fourth embodiment may further include a terminal device that can communicate with the estimation device 300 and the massage device 400, as described with reference to FIG. In this case, as described above, the terminal device may have a part of the functions of the estimation device 300.
（第５実施形態）
　第４実施形態では、推定装置３００が、加速度情報に基づいて、マッサージの効果の信頼度を算出する場合の例について説明した。第５実施形態では、推定装置３００が、ＳＶに関する値として使用し得る指標のうち、信頼度の高い指標を選択し、選択した指標に基づいて、マッサージの効果を判定する場合の例について説明する。 (Fifth embodiment)
In 4th Embodiment, the estimation apparatus 300 demonstrated the example in the case of calculating the reliability of the effect of a massage based on acceleration information. In the fifth embodiment, an example will be described in which the estimation apparatus 300 selects a highly reliable index from among indices that can be used as values related to SV, and determines the effect of massage based on the selected index. .
　第５実施形態に係るマッサージシステムの概略構成は、図１４で示した第４実施形態に係るマッサージシステム７００の概略構成と同様である。第５実施形態に係るマッサージシステムの概略構成の詳細については、説明を省略する。 The schematic configuration of the massage system according to the fifth embodiment is the same as the schematic configuration of the massage system 700 according to the fourth embodiment shown in FIG. Description of the schematic configuration of the massage system according to the fifth embodiment is omitted.
　第５実施形態に係るマッサージシステムにおいて、推定装置３００の制御部２２０は、ＳＶに関する値として使用し得る複数の指標について、標準偏差を算出する。制御部２２０は、加速度センサ２１３から取得した加速度情報に基づき、加速度の標準偏差を算出する。制御部２２０は、ＳＶに関する値の標準偏差と、加速度の標準偏差との相関係数を、ＳＶに関する値の指標ごとに算出する。具体的には、制御部２２０は、血流量の標準偏差と加速度の標準偏差との相関係数（第１相関係数）、血流速度の標準偏差と加速度の標準偏差との相関係数（第２相関係数）、血液量の標準偏差と加速度の標準偏差との相関係数（第３相関係数）、脈動血流波高の標準偏差と加速度の標準偏差との相関係数（第４相関係数）、並びに、脈動血流量の標準偏差と加速度の標準偏差との相関係数（第５相関係数）を算出する。 In the massage system according to the fifth embodiment, the control unit 220 of the estimation device 300 calculates a standard deviation for a plurality of indexes that can be used as values related to SV. The control unit 220 calculates a standard deviation of acceleration based on the acceleration information acquired from the acceleration sensor 213. The control unit 220 calculates a correlation coefficient between the standard deviation of the value related to SV and the standard deviation of the acceleration for each index of the value related to SV. Specifically, the control unit 220 has a correlation coefficient (first correlation coefficient) between the standard deviation of blood flow and the standard deviation of acceleration, and a correlation coefficient between the standard deviation of blood flow velocity and the standard deviation of acceleration ( (Second correlation coefficient), correlation coefficient between standard deviation of blood volume and standard deviation of acceleration (third correlation coefficient), correlation coefficient of standard deviation of pulsating blood flow wave height and standard deviation of acceleration (fourth correlation coefficient) Correlation coefficient) and a correlation coefficient (fifth correlation coefficient) between the standard deviation of pulsating blood flow and the standard deviation of acceleration.
　制御部２２０は、算出した第１相関係数から第５相関係数に基づき、マッサージの効果を判定するために使用する指標を決定する。制御部２２０は、例えば、第１相関係数から第５相関係数と、所定の閾値とを比較し、当該所定の閾値以下の相関係数となる指標を、マッサージの効果を判定するために使用する指標として決定する。制御部２２０は、当該所定の閾値以下の相関係数となる指標が複数ある場合は、最も相関係数が小さい指標を選択してもよい。 The control part 220 determines the parameter | index used in order to determine the effect of a massage based on the calculated 5th correlation coefficient from the 1st correlation coefficient. For example, the control unit 220 compares the first correlation coefficient to the fifth correlation coefficient with a predetermined threshold value, and determines an index that is a correlation coefficient equal to or lower than the predetermined threshold value to determine the effect of the massage. Decide as an indicator to use. The control unit 220 may select an index having the smallest correlation coefficient when there are a plurality of indices having a correlation coefficient equal to or less than the predetermined threshold.
　制御部２２０は、他の方法により、マッサージの効果を判定するために使用する指標を決定してもよい。例えば、制御部２２０は、算出した第１相関係数から第５相関係数を比較してもよい。制御部２２０は、比較の結果、最も値が低い相関係数に係る指標を、マッサージの効果を判定するために使用する指標として決定してもよい。 The control unit 220 may determine an index used to determine the effect of the massage by other methods. For example, the control unit 220 may compare the fifth correlation coefficient from the calculated first correlation coefficient. As a result of the comparison, the control unit 220 may determine an index related to the correlation coefficient having the lowest value as an index used to determine the effect of the massage.
　制御部２２０は、決定した指標のＳＶに関する値に基づいて、マッサージの効果を判定する。上述の方法で決定した指標は、ＳＶに関する値の指標のうち生体センサ２１０の変位の影響が小さい指標である。そのため、制御部２２０は、上記方法で決定した指標のＳＶに関する値に基づいて、マッサージの効果を判定することにより、より精度の高い判定結果を算出できる。マッサージ中に、生体センサ２１０の変位の影響を受けにくい指標は、動的に変化し得るが、本実施形態によれば、生体センサ２１０の変位の影響を受けにくい指標を選択し得る。 The control unit 220 determines the effect of the massage based on the SV value of the determined index. The index determined by the above-described method is an index that is less affected by the displacement of the biosensor 210 among the index values related to SV. Therefore, the control part 220 can calculate a more accurate determination result by determining the effect of massage based on the value regarding SV of the parameter | index determined by the said method. During the massage, the index that is not easily affected by the displacement of the biosensor 210 can change dynamically, but according to the present embodiment, the index that is not easily affected by the displacement of the biosensor 210 can be selected.
　次に、図１８を参照しながら、本実施形態に係るマッサージシステム７００による制御手順の一例について説明する。被検者は、推定装置３００とマッサージ装置４００とを装着して、推定装置３００による測定処理を開始するための所定の操作入力を行う。図１８に示すシーケンスは、当該所定の操作入力を行うと開始される。 Next, an example of a control procedure by the massage system 700 according to the present embodiment will be described with reference to FIG. The subject wears the estimation device 300 and the massage device 400 and performs a predetermined operation input for starting the measurement process by the estimation device 300. The sequence shown in FIG. 18 is started when the predetermined operation input is performed.
　まず、推定装置３００は、基底血流量を測定し（ステップＳ６０１）、測定した基底血流量に基づいて、ＳＶに関する値及びＨＲを算出する（ステップＳ６０２）。推定装置３００は、マッサージを開始させる指示をマッサージ装置４００に送信する（ステップＳ６０３）。マッサージ装置４００は、マッサージを開始させる指示に基づき、マッサージ部４１０による被検者へのマッサージを開始する（ステップＳ６０４）。推定装置３００は、マッサージ装置４００によるマッサージ中に、血流量を測定する（ステップＳ６０５）。推定装置３００は、加速度センサ２１３において、マッサージ中における生体センサ２１０の加速度情報を取得する（ステップＳ６０６）。ステップＳ６０１からステップＳ６０６の詳細は、それぞれ図１６のステップＳ４０１からステップＳ４０６と同様である。推定装置３００は、マッサージを行っている間、例えば継続的にステップＳ６０５及びステップＳ６０６を繰り返すことにより、血流量の測定と加速度情報の取得を行う。 First, the estimation apparatus 300 measures the basal blood flow (step S601), and calculates a value related to SV and HR based on the measured basal blood flow (step S602). The estimation apparatus 300 transmits an instruction to start massage to the massage apparatus 400 (step S603). The massage device 400 starts massage to the subject by the massage unit 410 based on an instruction to start massage (step S604). The estimation apparatus 300 measures the blood flow during the massage by the massage apparatus 400 (step S605). In the acceleration sensor 213, the estimation apparatus 300 acquires acceleration information of the biological sensor 210 during massage (step S606). Details of steps S601 to S606 are the same as steps S401 to S406 of FIG. 16, respectively. The estimation apparatus 300 measures blood flow and acquires acceleration information by repeating step S605 and step S606, for example, continuously while performing massage.

Should be configured to embody such a configuration. Each requirement shown in some embodiments can be freely combined.
　例えば、上記実施形態では、測定機構１２０が被検者の耳珠において生体情報を取得すると説明したが、生体情報の取得位置は、耳珠に限られず、生体情報を取得可能な任意の位置とすることができる。例えば、測定機構１２０は、被検者の耳甲介において生体情報を取得できる。 For example, in the above-described embodiment, it has been described that the measurement mechanism 120 acquires biological information in the subject's tragus, but the acquisition position of the biological information is not limited to the tragus, and an arbitrary position where the biological information can be acquired. can do. For example, the measurement mechanism 120 can acquire biological information in the concha of the subject.
　図２８は、測定機構１２０の一変形例を示す図であり、被検者の耳甲介において生体情報を取得可能な測定機構１２０の概略を示す図である。測定機構１２０は、挿入部１３１と、接触部１３２とを備える。 FIG. 28 is a diagram showing a modification of the measurement mechanism 120, and is a diagram showing an outline of the measurement mechanism 120 that can acquire biological information in the concha of the subject. The measurement mechanism 120 includes an insertion part 131 and a contact part 132.
　挿入部１３１は、被検者が推定装置を装着した際に、耳の外耳道に挿入される。つまり、被検者は、推定装置を装着する際に、挿入部１３１が耳の外耳道に挿入されるように、測定機構１２０を頭部に保持させる。接触部１３２は、耳甲介に接触する表面が曲面形状の部材である。接触部１３２は、耳甲介への接触面側に、生体情報を光学的に取得するための生体センサを備える。図２８では、生体センサが備えられる接触面上の位置を破線により示している。上記実施形態で説明した推定装置は、耳甲介で、生体情報として血流量を測定できる。 The insertion unit 131 is inserted into the ear canal when the subject wears the estimation device. That is, when the subject wears the estimation device, the subject holds the measurement mechanism 120 on the head so that the insertion unit 131 is inserted into the ear canal of the ear. The contact portion 132 is a member having a curved surface that contacts the concha. The contact unit 132 includes a biological sensor for optically acquiring biological information on the side of the contact surface to the concha. In FIG. 28, the position on the contact surface where the biosensor is provided is indicated by a broken line. The estimation apparatus described in the above embodiment can measure blood flow as biometric information using the concha.
　発明者らは、上記実施形態で説明した装置により、身体の状態の推定精度が向上することを確かめるため、実験を行った。ここで、発明者らが行った実験について説明する。 The inventors conducted an experiment in order to confirm that the apparatus described in the above embodiment improves the estimation accuracy of the body state. Here, an experiment conducted by the inventors will be described.
　実験では、被験者に対して、マッサージ装置を用いて、被験者の心拍に同期するマッサージ（以下「心拍同期マッサージ」ともいう）と、被験者の心拍に同期させないマッサージ（以下「心拍非同期マッサージ」ともいう）とを行った。心拍同期マッサージは、被験者の心拍に合わせて押圧を行うマッサージをいう。具体的には、心拍同期マッサージは、被験者の血流が末端側から心臓側に流れるタイミングで被験者を押圧する。これに対し、心拍非同期マッサージは、被験者の心拍とは無関係のタイミングで押圧を行うマッサージをいう。心拍同期マッサージは、心拍非同期マッサージと比較して、被験者の血流がさらに促進されやすくなるため、マッサージの効果が高くなると考えられる。つまり、心拍同期マッサージは、心拍非同期マッサージと比較して、ＳＶがより高くなり、ＨＲがより低くなると考えられる。発明者らは、心拍同期マッサージと心拍非同期マッサージとを行った場合において、どちらがマッサージの効果が高いと評価されるか、という判断基準に基づき、上記実施形態で説明した装置により身体の状態の推定精度が向上することを確かめた。すなわち、心拍同期マッサージを行っているときと、心拍非同期マッサージを行っているときとにおいて測定された血流量に基づいて算出されるＳＶ及びＨＲの値に基づき、上記実施形態で説明した装置による身体の状態の推定精度について評価を行った。 In the experiment, a massage synchronized with the heartbeat of the subject (hereinafter also referred to as “heartbeat synchronized massage”) and a massage that is not synchronized with the heartbeat of the subject (hereinafter also referred to as “heartbeat asynchronous massage”). And went. Heartbeat-synchronized massage refers to massage that presses according to the heartbeat of a subject. Specifically, the heart rate synchronous massage presses the subject at a timing when the blood flow of the subject flows from the terminal side to the heart side. On the other hand, a heartbeat asynchronous massage refers to a massage that performs pressing at a timing unrelated to the subject's heartbeat. The heart-beat synchronized massage is considered to increase the effect of the massage because the blood flow of the subject is further promoted more easily than the heart-rate asynchronous massage. In other words, it is considered that the synchronized heart massage has higher SV and lower HR than the asynchronous heart massage. The inventors have estimated the body state by the apparatus described in the above embodiment based on the judgment criteria of which is evaluated that the effect of the massage is higher when the heart rate synchronous massage and the heart rate asynchronous massage are performed. It was confirmed that the accuracy improved. That is, based on the values of SV and HR calculated based on the blood flow measured when performing the heart rate synchronous massage and when performing the heart rate asynchronous massage, the body by the device described in the above embodiment The estimation accuracy of the state of was evaluated.
　図２９は、発明者らが行った実験の実験手順を示す図である。被験者に対しては、前日に飲酒しないこと、及び十分な睡眠ととることを指示した。被験者に対しては、実験開始２時間以内に食事及び喫煙を行わないことを指示した。実験は、温度が２２℃～２６℃の室内で行った。実験を通して、一定のテンポを刻むメトロノームのアプリケーションを用いて音を出力させ、被験者に、音に合わせて呼吸を行うよう指示した。これは、自律神経が呼吸による影響を受ける場合があるため、呼吸のばらつきによる実験結果のばらつきを低減するためである。 FIG. 29 is a diagram showing an experimental procedure of an experiment conducted by the inventors. The subject was instructed not to drink the day before and to have enough sleep. Subjects were instructed not to eat or smoke within 2 hours of the start of the experiment. The experiment was performed in a room at a temperature of 22 ° C to 26 ° C. Throughout the experiment, a metronome application with a constant tempo was used to output sound, and subjects were instructed to breathe in time with the sound. This is because the autonomic nerve may be affected by respiration, and thus the variation in the experimental result due to the variation in respiration is reduced.
　実験は、被験者が、本明細書で説明した構造を有する推定装置を頭部に装着し、かつ、Finapres Medical Systems社製のフィナプレス（Finometer（登録商標） PRO）のカフを左手中指の指先に装着した状態で行った。ただし、実験では、被験者の耳甲介において血流量を測定する構造の推定装置を用いた。実験で用いた推定装置は、実験の趣旨に鑑み、血流量の測定にのみ用い、実施形態で説明したような身体の状態の推定は行っていない。フィナプレスは、被験者の血行動態を測定可能な機器である。 In the experiment, the subject wears an estimation device having the structure described in this specification on the head, and the cuff of the Finapres (Medical Systems) Finapress (Finometer (registered trademark) PRO) is applied to the fingertip of the middle finger of the left hand. It was performed in the state of wearing. However, in the experiment, an estimation device having a structure for measuring blood flow in the subject's ear concha was used. In view of the purpose of the experiment, the estimation device used in the experiment is used only for blood flow measurement, and does not estimate the body state as described in the embodiment. Finapless is a device that can measure the hemodynamics of a subject.
　推定装置及びフィナプレスを装着した被験者をマッサージ装置（マッサージチェア）に座らせて試験時の姿勢を確定し、まず、図２９に「安静０」として示すように、１０分間安静にした。 The subject wearing the estimation device and the FINA press was seated on a massage device (massage chair) to determine the posture at the time of the test. First, as shown in FIG. 29 as “rest 0”, the subject was rested for 10 minutes.
　安静０の期間が終了すると、図２９に「データ取得開始」として示すように、推定装置及びフィナプレスを起動し、推定装置及びフィナプレスによる被験者の血流量（データ）の測定を開始した。血流量の測定は、後述する第２のリフレッシュ期間が終了するまで継続される。 When the period of rest 0 ended, as shown in FIG. 29 as “data acquisition start”, the estimation device and FINAPRESS were started, and measurement of the blood flow (data) of the subject by the estimation device and FINAPRESS was started. The measurement of the blood flow is continued until a second refresh period to be described later ends.
　血流量の測定が開始されると、図２９に「安静１」として示すように、被験者は１０分間安静の状態を維持した。この間、推定装置及びフィナプレスによる血流量の測定が行われる。 When measurement of blood flow was started, the subject maintained a state of rest for 10 minutes, as shown as “rest 1” in FIG. During this time, blood flow is measured by the estimation device and FINAPRESS.
　１０分間の「安静１」の期間の後、マッサージ装置を起動して、被験者に対して心拍同期マッサージを１０分間行った。心拍同期マッサージを行っている間に、「安静１」の期間にフィナプレスで測定した被験者の血流量に基づき、「安静１」の期間における被験者のＳＶの平均値を算出した。 After 10 minutes “rest 1” period, the massage device was activated and the subject was subjected to heart rate synchronized massage for 10 minutes. While performing the heart rate synchronous massage, the average value of the subject's SV during the “rest 1” period was calculated based on the blood flow of the subject measured with Finapless during the “rest 1” period.
　１０分間の心拍同期マッサージを行った後、マッサージ装置を停止し、１０分間の第１のリフレッシュ期間を設けた。第１のリフレッシュ期間は、被験者のＳＶを、心拍同期マッサージを行う前のＳＶに戻すために設けられた期間である。これにより、次の心拍非同期マッサージの開始時の条件を、心拍同期マッサージの開始時の条件に近付けることができる。１０分間の第１のリフレッシュ期間によっても被験者のＳＶが心拍同期マッサージを行う前のＳＶに戻らない場合には、追加のリフレッシュ期間を設けた。追加のリフレッシュ期間は、被験者のＳＶが心拍同期マッサージを行う前のＳＶに戻るまで継続してよい。 After 10 minutes of heart rate synchronized massage, the massage device was stopped and a 10 minute first refresh period was provided. A 1st refresh period is a period provided in order to return test subject's SV to SV before performing heart rate synchronous massage. Thereby, the condition at the start of the next heart rate asynchronous massage can be brought closer to the condition at the start of the heart rate synchronized massage. If the subject's SV did not return to the SV before performing the heart rate synchronized massage even after the first refresh period of 10 minutes, an additional refresh period was provided. The additional refresh period may continue until the subject's SV returns to the SV prior to the heart rate synchronized massage.
　第１のリフレッシュ期間により、被験者のＳＶを、心拍同期マッサージを行う前のＳＶに戻した後、マッサージ装置を起動して、被験者に対して心拍非同期マッサージを１０分間行った。 In the first refresh period, the subject's SV was returned to the SV before performing the heart rate synchronous massage, and then the massage device was activated to perform the heart rate asynchronous massage for the subject for 10 minutes.
　１０分間の心拍非同期マッサージを行った後、マッサージ装置を停止し、１０分間の第２のリフレッシュ期間を設けた。 After 10 minutes of heart rate asynchronous massage, the massage device was stopped and a second refresh period of 10 minutes was provided.
　第２のリフレッシュ期間が経過した後、推定装置及びフィナプレスを停止して、血流量の測定を終了し、実験を終了した。 After the second refresh period, the estimation device and FINAPRESS were stopped, the blood flow measurement was finished, and the experiment was finished.
　このような実験を、１０人の被験者に対して実施し、フィナプレス及び推定装置による血流量の測定精度について考察した。 Such an experiment was carried out on 10 subjects, and the measurement accuracy of blood flow with Finapress and an estimation device was considered.
　まず、フィナプレスによる血流量の測定精度について考察する。発明者らは、フィナプレスが測定した血流量に基づいて、心拍同期マッサージを行っている期間、第１のリフレッシュ期間、心拍非同期マッサージを行っている期間、及び第２のリフレッシュ期間の４つの期間について、それぞれＨＲ及びＳＶを算出した。 First, let us consider the accuracy of blood flow measurement by FINAPRESS. The inventors have four periods, a period during which a heartbeat-synchronized massage is performed, a first refresh period, a period during which a heartbeat asynchronous massage is performed, and a second refresh period, based on the blood flow measured by Finapless. HR and SV were calculated for each.
　図３０及び図３１は、実験結果を示す図である。図３０は、フィナプレスが測定した血流量に基づいて算出されたＨＲを示す図である。図３１は、フィナプレスが測定した血流量に基づいて算出されたＳＶを示す図である。図３０及び図３１において、横軸は４つの期間を示す。図３０において、縦軸は１分間の脈拍数を示す。図３１において、縦軸は各期間における平均のＳＶの値を示す。 30 and 31 are diagrams showing experimental results. FIG. 30 is a diagram illustrating HR calculated based on the blood flow measured by the FINAPRESS. FIG. 31 is a diagram showing SV calculated based on the blood flow measured by Finapless. 30 and 31, the horizontal axis indicates four periods. In FIG. 30, the vertical axis indicates the pulse rate for 1 minute. In FIG. 31, the vertical axis indicates the average SV value in each period.
　心拍同期マッサージを行っている期間と、心拍非同期マッサージを行っている期間とのＨＲを比較すると、被験者１０人のうち、心拍同期マッサージを行っている期間の方が心拍非同期マッサージを行っている期間よりもＨＲが低いという結果が得られたのは４人であった。心拍同期マッサージを行っている期間と、心拍非同期マッサージを行っている期間とのＳＶを比較すると、被験者１０人のうち、心拍同期マッサージを行っている期間の方が心拍非同期マッサージを行っている期間よりもＳＶが高いという結果が得られたのは５人であった。上述のように、心拍同期マッサージを行っている期間は、心拍非同期マッサージを行っている期間と比較して、ＨＲが低くなり、ＳＶが高くなると考えられる。仮に、心拍非同期マッサージを行っている期間よりも心拍同期マッサージを行っている期間の方がＨＲが低いという結果、及び、心拍非同期マッサージを行っている期間よりも心拍同期マッサージを行っている期間の方がＳＶが高いという結果を、それぞれ正確な測定結果と定義した場合、フィナプレスで正確な測定結果が得られたのは、約半数であった。そのため、フィナプレスでの測定では、必ずしも正確な測定結果が得にくく、血流量の測定は必ずしも精度が高いとは言えない。 When comparing the HR between the period during which heart rate synchronized massage is performed and the period during which heart rate asynchronous massage is performed, among the 10 subjects, the period during which heart rate synchronized massage is performed is the period during which heart rate asynchronous massage is performed It was 4 people who got the result that HR was lower than that. Comparing the SV of the period during which the heart rate synchronized massage is performed and the period during which the heart rate asynchronous massage is performed, among the 10 subjects, the period during which the heart rate synchronized massage is performed is the period during which the heart rate asynchronous massage is performed. Five people had a higher SV. As described above, it is considered that the HR is lower and the SV is higher in the period during which the heart rate synchronized massage is performed, compared to the period during which the heart rate asynchronous massage is performed. As a result, the period when the heart rate synchronized massage is performed is lower than the period when the heart rate synchronized massage is performed, and the period when the heart rate synchronized massage is performed than the period when the heart rate asynchronous massage is performed. When the results of higher SV were defined as accurate measurement results, about half of the results were obtained with FINAPRESS. Therefore, it is difficult to obtain an accurate measurement result in the measurement with the FINA press, and the blood flow measurement is not necessarily highly accurate.
　次に、推定装置が測定した血流量の測定精度について考察する。図３２は、実験結果を示す図であり、推定装置が測定した血流量に基づいて算出されたＨＲを示す図である。図３２において、横軸は４つの期間を示し、縦軸はＨＲの値を示す。推定装置が測定した血流量の測定精度の考察にあたっては、まず、データの信頼性判定を行った。データの信頼性判定は、データの信頼性の有無を判定するものであり、具体的には、例えばノイズを含むデータを排除する処理をいう。データの信頼性判定は、フィナプレスにより測定された血流量に基づいて算出したＨＲと、推定装置により測定された血流量に基づいて算出したＨＲとを比較することにより行った。図３３は、フィナプレスにより測定された血流量に基づいて算出したＨＲと、推定装置により測定された血流量に基づいて算出したＨＲとの差分を示す図である。図３３において、横軸は各期間を示し、縦軸は差分を示す。フィナプレスにより測定された血流量に基づいて算出したＨＲと、推定装置により測定された血流量に基づいて算出したＨＲとの値が近いほど、差分は０に近づく。 Next, the measurement accuracy of the blood flow measured by the estimation device will be considered. FIG. 32 is a diagram showing experimental results, and is a diagram showing HR calculated based on the blood flow measured by the estimation device. In FIG. 32, the horizontal axis indicates four periods, and the vertical axis indicates the value of HR. In considering the measurement accuracy of the blood flow measured by the estimation device, first, the reliability of the data was determined. The data reliability determination is to determine whether or not the data is reliable, and specifically refers to a process of eliminating data including noise, for example. The reliability of the data was determined by comparing the HR calculated based on the blood flow measured by Finapless and the HR calculated based on the blood flow measured by the estimation device. FIG. 33 is a diagram illustrating a difference between the HR calculated based on the blood flow measured by the FINA press and the HR calculated based on the blood flow measured by the estimation device. In FIG. 33, the horizontal axis indicates each period, and the vertical axis indicates the difference. The difference approaches 0 as the value of HR calculated based on the blood flow measured by Fina Press and HR calculated based on the blood flow measured by the estimation device are closer.
　ここで、図３３に示す差分は０が近い場合には、データの信頼性があると言える。なぜなら、ＨＲは、血流波形のピークに基づいて算出されるので、ノイズを含まずに血流量を適切に測定できていれば、フィナプレスにより指で測定された血流量に基づいて算出したＨＲと、推定装置により耳甲介で測定された血流量に基づいて算出したＨＲとは、ほぼ同じ値を取るからである。同様の理由から、図３３に示す差分が０から離れている程、データの信頼性が低いと言える。発明者らは、図３３に示す図に基づき、領域Ｒで示した７名分のデータを信頼性があるデータであると判定した。 Here, if the difference shown in FIG. 33 is close to 0, it can be said that the data is reliable. Because HR is calculated based on the peak of the blood flow waveform, if the blood flow can be appropriately measured without including noise, the HR calculated based on the blood flow measured with a finger by Finapless. This is because the HR calculated based on the blood flow measured by the concha by the estimation device takes almost the same value. For the same reason, it can be said that the more reliable the difference shown in FIG. Based on the diagram shown in FIG. 33, the inventors have determined that the data for the seven persons shown in the region R are reliable data.
　図３４は、実験結果を示す図であり、推定装置が測定した血流量に基づいて算出されたＳＶを示す図である。図３４において、横軸は４つの期間を示し、縦軸は各期間における平均のＳＶの値を示す。図３４は、信頼性があると判定された７名分のデータを図示したものである。図３４に示した７名のうち、心拍同期マッサージを行っている期間の方が心拍非同期マッサージを行っている期間よりもＳＶが高いという結果が得られたのは６人であった。すなわち、推定装置によれば、７名中６名が正確な測定結果を得られた。従って、フィナプレスよりも、推定装置の方が、血流量の測定精度が高いと言える。 FIG. 34 is a diagram showing the experimental results, and is a diagram showing SV calculated based on the blood flow measured by the estimation device. In FIG. 34, the horizontal axis indicates four periods, and the vertical axis indicates the average SV value in each period. FIG. 34 illustrates data for seven persons determined to be reliable. Among the seven persons shown in FIG. 34, six persons obtained a result that SV was higher in the period in which the heart rate synchronous massage was performed than in the period in which the heart rate asynchronous massage was performed. That is, according to the estimation apparatus, 6 out of 7 people obtained accurate measurement results. Therefore, it can be said that the estimation apparatus has higher blood flow measurement accuracy than the FINA press.
　発明者らは、再現性を確認するため、さらに、１名の被験者について、図２９を参照して説明した実験を４日間連続して行った。発明者らは、４日間の実験で取得したデータについて、上述した方法と同様の方法でデータの信頼性判定を行い、図３５に示すように、３日分のデータについて、信頼性があるデータであると判定した。 In order to confirm the reproducibility, the inventors further conducted the experiment described with reference to FIG. 29 for one subject for four consecutive days. The inventors performed data reliability determination using the same method as described above for the data acquired in the 4-day experiment, and as shown in FIG. It was determined that
　図３６は、実験結果を示す図であり、推定装置が測定した血流量に基づいて算出されたＳＶを示す図である。図３６において、横軸は４つの期間を示し、縦軸は各期間における平均のＳＶの値を示す。図３６は、信頼性があると判定された３日分のデータを図示したものである。図３６に示した３日分のデータのうち、２日分については、心拍同期マッサージを行っている期間の方が心拍非同期マッサージを行っている期間よりもＳＶが高いという結果が得られた。これにより、ある程度の再現性が確認できたと言える。 FIG. 36 is a diagram showing the experimental results, and is a diagram showing SV calculated based on the blood flow measured by the estimation device. In FIG. 36, the horizontal axis represents four periods, and the vertical axis represents the average SV value in each period. FIG. 36 illustrates data for three days determined to be reliable. Among the data for 3 days shown in FIG. 36, for 2 days, the SV was higher in the period during which the heart rate synchronized massage was performed than in the period during which the heart rate asynchronous massage was performed. As a result, it can be said that a certain degree of reproducibility was confirmed.
　以上の実験結果から、フィナプレスよりも、推定装置の方が、血流量の測定精度が高いと言える。すなわち、実験から、耳甲介ではより高い精度で血流量を測定できると言うことができ、耳甲介における血流量取得の有効性が確認された。実験は、耳甲介で血流量を取得したことにより行ったが、例えば耳珠も、耳甲介と同様に、動脈と静脈を結ぶシャントが少なく、バソモーション（長周期的な血流のゆらぎ）の影響も少ないことから、同様の効果が得られる。すなわち、耳珠においても、高い精度で血流量を測定できると言える。 From the above experimental results, it can be said that the estimation device has higher blood flow measurement accuracy than the FINA press. That is, it can be said from experiments that blood flow can be measured with higher accuracy in the concha, and the effectiveness of blood flow acquisition in the concha was confirmed. The experiment was performed by acquiring blood flow through the concha. For example, the tragus also has a small number of shunts connecting arteries and veins, as in the concha. ) Has little influence, and the same effect can be obtained. That is, it can be said that blood flow can be measured with high accuracy even in the tragus.
