Description

本発明は横臥状態の人体の向きを検出して、いわゆる睡眠時無呼吸症候群の診断に用いられる装置に関するものである。 The present invention relates to a device that detects the orientation of a lying human body and is used to diagnose so-called sleep apnea syndrome.

睡眠時無呼吸症候群は睡眠時に突然呼吸が停止する疾患であり、多くは肥満傾向のある人が睡眠時の身体の向きによって気管が塞がることによって引き起こされる。
つまり、睡眠時に無意識に横向きになった際に、気道の一部が重力によって垂れ下がり閉塞されることによって引き起こされると考えられている。
したがって、睡眠時無呼吸症候群の診断には睡眠時の身体の向きを観察することが重要な要素となっているのであるが、この睡眠時の身体の向きのデータをとるためには、従来半導体センサ（加速度センサ）を粘着テープにより胸部の複数箇所に貼り付け、これらセンサからの出力信号を解析して身体の向きのデータとしていた。 Sleep apnea syndrome is a disease in which breathing stops suddenly during sleep, and is often caused by obesity-prone people who have their trachea blocked by their body orientation during sleep.
In other words, it is thought that a part of the airway hangs down due to gravity and is blocked when it is unconsciously turned sideways during sleep.
Therefore, observing the orientation of the body during sleep is an important factor in diagnosing sleep apnea syndrome, but in order to collect data on the orientation of the body during sleep, conventional semiconductors Sensors (acceleration sensors) were attached to a plurality of locations on the chest with adhesive tape, and output signals from these sensors were analyzed to obtain body orientation data.

しかし、上記半導体センサを用いた装置はセンサ（デバイス）そのものが高価である上に、それに付随する回路が複雑な半導体センサを直接粘着テープで被検者の身体に貼り付けるという、面倒な取り扱い法であるという欠点がある。
また、粘着テープで身体に貼り付ける、あるいはそれに替わる方法としてのひもなどで身体に巻きつける方法は、身体にいくらかの負荷を与え、皮膚の弱い被検者では皮膚に障害を残す恐れもある。 However, the apparatus using the above-described semiconductor sensor is expensive, and a complicated handling method in which a semiconductor sensor having a complicated circuit is directly attached to the body of the subject with an adhesive tape. There is a drawback of being.
Moreover, the method of sticking on a body with an adhesive tape, or the method of wrapping around a body with the string as an alternative method gives a load to a body and there exists a possibility that the subject with weak skin may leave the skin damaged.

一方、特に無呼吸症候群の診断用と謳ってはいないが、立位時あるいは歩行時などの身体の状態（座っているか、歩行しているか、寝ているかなど）を検知する装置として特開平１０−１１１９９０号公報に開示された装置がある。
この装置は、縦方向振動センサ、横方向振動センサ、傾斜センサおよびCPUを搭載した装置本体を人間の背中に貼り付け、上記各センサそれぞれからの信号に基づいて予め定められたテーブルにそれら信号のオン・オフ状態をあてはめて人間の状態を判別するものである。
この装置では、もちろん人間の横臥時の向きを判別できないし、詳細は開示されていないものの、装置本体を人体に固定する手段は簡便ではないことが推定される。
特開平１０−１１１９９０号公報 On the other hand, although it is not particularly sought for diagnosing apnea syndrome, it is disclosed as a device for detecting a physical state (sitting, walking, sleeping, etc.) when standing or walking. There is an apparatus disclosed in Japanese Patent No. -111990.
In this device, a device body equipped with a longitudinal vibration sensor, a lateral vibration sensor, a tilt sensor and a CPU is attached to a human back, and the signals are stored in a predetermined table based on signals from the respective sensors. A human state is discriminated by applying an on / off state.
Of course, with this device, the orientation of a person lying down cannot be determined, and although details are not disclosed, it is presumed that means for fixing the device body to the human body is not simple.
Japanese Patent Laid-Open No. 10-111990

そこで、本発明は特に横臥状態の人体の向きを検出するために、簡便な取り扱い法でもって被検者に装着できて、かつ構造が簡単な転倒検出センサをセンサデバイスとして用い全体の構造も簡素にでき、そうであっても横臥時の人体の向きのおおよそを、少なくとも睡眠時無呼吸症候群の診断用としては充分に精度のあるデータを得ることができる向き検出装置を提供するものである。   Therefore, in order to detect the orientation of the human body in the lying state, the present invention uses a fall detection sensor that can be attached to the subject with a simple handling method and has a simple structure as a sensor device, and the overall structure is also simple. It is possible to provide an orientation detection device that can obtain data with sufficient accuracy for diagnosing sleep apnea syndrome at least about the orientation of the human body when lying down.

本発明は、人体の首部に装着するベルト状の輪体と、該輪体を人体に対して固定する固定具と、該輪体上の周方向において互いに間隔を保って配置固定された３個以上の転倒検出スイッチと、該転倒検出スイッチからのオン、オフ信号により前記輪体の角度を検出する電気回路からなる横臥状態の人体の向き検出装置である。   The present invention relates to a belt-shaped ring mounted on the neck of a human body, a fixture for fixing the ring to the human body, and three pieces arranged and fixed at intervals in the circumferential direction on the ring. This is a human body orientation detection device in the lying state comprising the above-described fall detection switch and an electric circuit for detecting the angle of the ring body by an on / off signal from the fall detection switch.

また、本発明は、前記３個以上の転倒検出スイッチが前記輪体の周の９０度の角度範囲に配置され、一端の転倒検出スイッチの固定位置から４５度離間した位置と、９０度離間した位置にそれぞれ転倒検出スイッチが固定された横臥状態の人体の向き検出装置である。   Further, according to the present invention, the three or more fall detection switches are arranged in an angular range of 90 degrees around the circumference of the ring body, and are separated by 90 degrees from a position 45 degrees away from the fixed position of the fall detection switch at one end. This is a human body orientation detection device in which the fall detection switch is fixed at each position.

また、本発明は、前記固定具が人体に被着された衣服を挟むクリップである横臥状態の人体の向き検出装置である。   In addition, the present invention is a human body orientation detection device in a lying state, wherein the fixing tool is a clip that sandwiches clothes attached to the human body.

また、本発明は、前記電気回路が前記転倒検出スイッチからのオン、オフ信号の組み合わせにしたがって異なった出力電圧を出力するラダー抵抗を含む回路である横臥状態の人体の向き検出装置である。   In addition, the present invention is a human body orientation detection device in a recumbent state in which the electric circuit is a circuit including a ladder resistor that outputs different output voltages in accordance with a combination of on and off signals from the fall detection switch.

本発明の人体の向き検出装置は、横臥状態の人体に簡単な取り扱いでもって装着でき、被検者になんら負担を与えず、かつ構造が簡単で故障が少なく安価に製造でき、少なくとも睡眠時無呼吸症候群の診断用としては充分に精度のあるデータを得ることができる。 The human body orientation detection device of the present invention can be mounted on a lying human body with simple handling, does not give any burden to the subject, is simple in structure, can be manufactured inexpensively, and is at least free of sleep. For diagnosis of respiratory syndrome, sufficiently accurate data can be obtained.

図１に本発明に係る向き検出装置の全体外観を示し、図２にはその一部を拡大して示し、図３に横臥状態の人体に装着した状態を示す。 FIG. 1 shows the overall appearance of the orientation detection apparatus according to the present invention, FIG. 2 shows an enlarged view of a part thereof, and FIG. 3 shows a state where the orientation detection apparatus is mounted on a lying human body.

本実施形態の向き検出装置は図１、２および３に示したように、長尺のベルト体１を接続ボックス２でもって接続することにより一つの環となり、その内部に複数の転倒検出スイッチ３を備えたベルト状の輪体４と、接続ボックス２から延びる短いコード５端に設けたクリップ６と前記転倒スイッチ３からの信号を接続ボックス２内の電気回路７を介して無線受信し、前記輪体４の角度を検出・記録するデータ収集装置１１とから成る。 As shown in FIGS. 1, 2 and 3, the orientation detection device of the present embodiment forms a single ring by connecting a long belt body 1 with a connection box 2, and a plurality of fall detection switches 3 are provided therein. A belt-like ring body 4 provided with a clip 6 provided on the end of a short cord 5 extending from the connection box 2 and a signal from the overturning switch 3 via an electric circuit 7 in the connection box 2, And a data collecting device 11 for detecting and recording the angle of the ring body 4.

輪体４はその内部に前記転倒スイッチ３を搭載したフレキシブル基盤８を備え、かつ全体が屈曲自在になるように合成樹脂または布などの柔軟な外装材９で覆われている。
このように外側が柔軟な材質で覆われることから、人体へ長時間接触していても、人体に負担となったり、不快な感触を与えない。 The ring body 4 includes a flexible base 8 on which the fall switch 3 is mounted, and is covered with a flexible exterior material 9 such as a synthetic resin or cloth so that the entire body can be bent.
Since the outer side is covered with the flexible material in this way, even if it is in contact with the human body for a long time, it does not become a burden on the human body or give an unpleasant feel.

接続ボックス２はちょうどベルトのバックルのような構造を備え、輪体４の径を調節できて、それを人体の首部に装着した際に首まわりに合うようにできている。
接続ボックス２内のフレキシブル基盤８上には、後に詳述する転倒検出スイッチ３からの信号を入力して、輪体４の角度に応じた電圧を出力する電気回路７と、その電圧信号を前記データ収集装置１１へ無線送信する無線回路１２が内装されている。
なお、クリップ６は接続ボックス２から延びるコード５端に設けたが、輪体４の他の位置に接続するようにしてもよい。
また、クリップ６は本実施形態では鰐口クリップ状のものを採用したが、被着した衣服に挟み付けるものであればどのような構造のものでもよい。
さらに、固定具としてはクリップに限らず衣服に挿通するピンであってもよい。
また、前記コード５は無線回路１２のアンテナ機能を兼ね備えたものでもよい。 The connection box 2 has a structure like a belt buckle, and can adjust the diameter of the ring body 4 so that it fits around the neck when it is attached to the neck of a human body.
On the flexible board 8 in the connection box 2, an electric circuit 7 for inputting a signal from a fall detection switch 3, which will be described in detail later, and outputting a voltage corresponding to the angle of the ring body 4, A wireless circuit 12 for wireless transmission to the data collection device 11 is provided.
The clip 6 is provided at the end of the cord 5 extending from the connection box 2, but may be connected to another position of the ring body 4.
Moreover, although the clip 6 used the shape of a mouth clip in this embodiment, what kind of structure may be sufficient as long as it is pinched | interposed into the clothes which adhered.
Further, the fixing tool is not limited to the clip, but may be a pin inserted into the clothes.
Further, the cord 5 may have the antenna function of the radio circuit 12.

次に輪体内に設けた転倒検出スイッチ３について説明する。
転倒検出スイッチ３は図５に示したように接点a,b,c,dを有していて、矢印方向に傾いた際に上記接点（a-b間またはc-d間）がオンになる（導通する）ものであり、適正に設定された感応角度Θを有している。
この実施形態の場合、説明の簡明を期するために輪体の周に９０度の角度にわたって３個の転倒検出スイッチを設けた例を示し、上記感応角度は３０度に設定してある。
また、転倒検出スイッチは図８に示したような金属ボール１３と、その金属ボール１３がある感応角度でもって入り込む穴１４を有した接点板１５とから成るものであってもよい。 Next, the fall detection switch 3 provided in the ring will be described.
The fall detection switch 3 has contacts a, b, c, and d as shown in FIG. 5, and the contacts (between ab or cd) are turned on (conducted) when tilted in the direction of the arrow. And has a properly set sensitivity angle Θ.
In the case of this embodiment, in order to simplify the explanation, an example in which three fall detection switches are provided on the circumference of the ring body over an angle of 90 degrees is shown, and the sensitivity angle is set to 30 degrees.
Further, the fall detection switch may be composed of a metal ball 13 as shown in FIG. 8 and a contact plate 15 having a hole 14 for entering the metal ball 13 at a certain sensitive angle.

この実施形態の場合、輪体４の周には図４に模式的に示したように９０度の角度範囲に３個の転倒検出スイッチ３a、３b、３cを設けてある。すなわち、両端のスイッチ３a，３cが９０度の角度離れ、その中間４５度の位置にもスイッチ３bが設けてある。 In the case of this embodiment, three fall detection switches 3a, 3b, 3c are provided on the circumference of the ring body 4 in an angle range of 90 degrees as schematically shown in FIG. That is, the switches 3a and 3c at both ends are separated from each other by an angle of 90 degrees, and the switch 3b is provided at an intermediate position of 45 degrees.

これら検出スイッチ３a，３b，３cは前記のとおり感応角度が３０度であるので、輪体の回転（角度の傾き）によって次のようにオン、オフ信号を出力する。
すなわち、まず図４の状態（人体が真上を向いているとする）では、スイッチ３aとスイッチ３bがオン信号を出力し、スイッチ３cがオフとなる。
次に、図４の状態から矢印R方向に４５度回転した状態（人体が斜めに向いた状態）を考えると、今度はスイッチ３aとスイッチ３cがオン信号を出力し、スイッチ３bがオフとなる。
同様に、さらに矢印R方向に４５度回転した状態（人体が完全に左右どちらかの横に向いた状態）を考えると、今度はスイッチ３bとスイッチ３cがオンとなり、スイッチ３aがオフとなる。
上記のように人体の向きによって輪体４の角度が変化し、それに伴って各検出スイッチ３a，３b，３cからのオン、オフ信号のパターンが変化する。
そして、この信号が前述のとおり接続ボックス２内の電気回路７に入力され所定の電圧信号に変換されて前記データ収集装置１１へ送信される。 Since the detection switches 3a, 3b, and 3c have a sensitivity angle of 30 degrees as described above, an on / off signal is output as follows according to the rotation of the ring (angle inclination).
That is, first, in the state of FIG. 4 (assuming that the human body is facing directly above), the switch 3a and the switch 3b output an on signal, and the switch 3c is turned off.
Next, considering a state rotated 45 degrees in the direction of arrow R from the state of FIG. 4 (a state where the human body is inclined), this time, the switch 3a and the switch 3c output an ON signal and the switch 3b is turned OFF. .
Similarly, when considering a state in which the human body is further rotated 45 degrees in the direction of arrow R (a state where the human body is completely turned to the left or right), switch 3b and switch 3c are now turned on and switch 3a is turned off.
As described above, the angle of the ring body 4 changes depending on the orientation of the human body, and the pattern of the on / off signals from the detection switches 3a, 3b, 3c changes accordingly.
Then, this signal is input to the electric circuit 7 in the connection box 2 as described above, converted into a predetermined voltage signal, and transmitted to the data collection device 11.

次に前記電気回路について説明する。
図６に示したように、本実施形態の電気回路７は前記転倒検出スイッチ３a，３b，３cをそれぞれ基準電圧に並列に接続し、出力側に抵抗R1,R2からなるラダー抵抗を設けたものであり、抵抗R1と抵抗R2の値を２：１にすると出力電圧として図７に示す特性をもったものが得られる。
すなわち、前述した輪体４の回転（人体の向き）に応じた出力電圧が電気回路から得られるようになっている。
なお、上記転倒検出スイッチ３a，３b，３cと電気回路７の説明は簡明を期するためにスイッチが輪体上の９０度範囲内に３個配置された例を示したが、さらに人体の向きの詳細を検知するために次のように構成してもよい。 Next, the electric circuit will be described.
As shown in FIG. 6, the electric circuit 7 of this embodiment has the fall detection switches 3a, 3b, 3c connected in parallel to the reference voltage, respectively, and a ladder resistor composed of resistors R1, R2 is provided on the output side. When the values of the resistors R1 and R2 are 2: 1, an output voltage having the characteristics shown in FIG. 7 can be obtained.
That is, an output voltage corresponding to the rotation (the direction of the human body) of the ring body 4 described above can be obtained from the electric circuit.
The above description of the fall detection switches 3a, 3b, 3c and the electric circuit 7 shows an example in which three switches are arranged within a 90 degree range on the ring body for the sake of simplicity. In order to detect the details, it may be configured as follows.

すなわち、輪体４の周９０度範囲内に５〜６個の転倒検出スイッチを等間隔に配置し、それぞれの感応角度を適正に調整すると共に、前記電気回路のラダーを５〜６段に増やすことにより人体の向きをより詳細に検出することができる。
また、輪体の周の１８０度の範囲内に等間隔に５個の転倒検出スイッチを配置し、電気回路７にはぞれぞれに接続したラダー抵抗を設けて、人体の向きを１８０度の範囲（つまり、左へ完全に横向いた状態から仰向けを経て右へ完全に横向いた状態）で検出しうるようにできる。 In other words, 5 to 6 fall detection switches are arranged at equal intervals within the 90 degree circumference of the ring body 4, and the sensitivity angle of each is adjusted appropriately, and the ladder of the electric circuit is increased to 5 to 6 stages. Thus, the orientation of the human body can be detected in more detail.
In addition, five fall detection switches are arranged at equal intervals within the range of 180 degrees around the circumference of the ring body, and ladder resistors connected to each are provided in the electric circuit 7 so that the orientation of the human body is 180 degrees. (I.e., from a state of being completely laterally directed to the left to a state of being completely laterally directed to the right after being turned upside down).

さらに、９０度の範囲に３個のスイッチ３a，３b，３cを配置した前述の例であっても各転倒検出スイッチの２種の接点（a-b間、c-d間）からの別々のオン、オフ信号を利用し、次のようにして人体の１８０度にわたる向きの変化を検出することもできる。
すなわち、各スイッチ３a，３b，３cのa-b接点を並列に接続した図６の電気回路と、同様に各スイッチ３a，３b，３cのc-d接点を並列に接続した図６の電気回路を設ける。
つまり、図６の電気回路を右向き用と左向き用に２つ設ける。
そうすれば仮に人体が右を向いている場合に、各スイッチのa-b接点が反応する際、各スイッチのc-d接点は確実にすべてオフであり、逆に人体が左を向いている場合には各スイッチのa-b接点はすべてオフでc-d接点がその傾きに応じて反応する。
したがって、人体が右を向いている際には右向き用の電気回路からのみ出力が現れるのでそれを利用し、左を向いている際には左向き用の電気回路からのみ出力が現れるのでそれを利用してそれぞれの向きの角度の深さを検知することができる。 Furthermore, even in the above-described example in which three switches 3a, 3b, 3c are arranged in a range of 90 degrees, separate on / off signals from the two contact points (between ab and cd) of each fall detection switch. , And a change in the orientation of the human body over 180 degrees can be detected as follows.
That is, the electrical circuit of FIG. 6 in which the ab contacts of the switches 3a, 3b, 3c are connected in parallel and the electrical circuit of FIG. 6 in which the cd contacts of the switches 3a, 3b, 3c are connected in parallel are provided.
That is, two electric circuits in FIG. 6 are provided for the right direction and the left direction.
Then, if the human body is facing right, when the ab contact of each switch reacts, all the cd contacts of each switch are surely off, and conversely, if the human body is facing left, All the ab contacts of the switch are off and the cd contact reacts according to its inclination.
Therefore, when the human body is facing right, the output appears only from the right-facing electrical circuit, so use it, and when facing the left, the output appears only from the left-facing electrical circuit. And the depth of the angle of each direction can be detected.

次にデータ収集装置１１について説明する。
この実施形態のデータ収集装置１１は、前記電気回路７の無線回路１２を介して送信されてくる電圧信号を受信する受信回路と受信した信号を経時的に記録する記録部を備えており、被検者が眠っている間に発信された電圧信号を蓄積できるようになっている。
もちろん、上記記録部に記録されたデータは後から取り出してモニタ画面等で見ることもできるし、適当な用紙に印字して見ることもできる。
なお、上記データ収集装置１１は無線回路を備えてリアルタイムで前記電気回路からの電圧信号（人体の向きの信号）を受信し、記録するようになっていたが、次のように構成して実質上データ収集装置を不要とすることもできる。 Next, the data collection device 11 will be described.
The data collection device 11 of this embodiment includes a receiving circuit that receives a voltage signal transmitted via the radio circuit 12 of the electric circuit 7 and a recording unit that records the received signal over time. The voltage signal transmitted while the examiner is sleeping can be stored.
Of course, the data recorded in the recording unit can be taken out later and viewed on a monitor screen or the like, or printed on an appropriate sheet of paper.
The data collection device 11 includes a wireless circuit and receives and records a voltage signal (a signal of the human body direction) from the electric circuit in real time. The upper data collection device can be dispensed with.

すなわち、前記接続ボックス２内の無線回路１２に代えて電気回路７から順次出力されてくる電圧信号を蓄積するメモリ回路を設ければ、このメモリ回路に所定時間中のデータが蓄積されるので、診断が終わって輪体を被検者の首から外し、このメモリ回路を外部のコンピュータ等に接続して蓄積されたデータを取り出せばよい。
あるいは、さらに上記メモリ回路に着脱自在にフラッシュメモリ等の記録媒体を接続しておけば、診断が終わってこの記録媒体のみを輪体から取り外してコンピュータ等に接続すればよい。 That is, if a memory circuit that accumulates voltage signals sequentially output from the electric circuit 7 is provided instead of the radio circuit 12 in the connection box 2, data for a predetermined time is accumulated in the memory circuit. After the diagnosis is completed, the wheel is removed from the subject's neck, and this memory circuit is connected to an external computer or the like to retrieve the accumulated data.
Alternatively, if a recording medium such as a flash memory is detachably connected to the memory circuit, only the recording medium is removed from the ring and connected to a computer or the like after diagnosis.

次に、睡眠時無呼吸症候群の診断に例をとって使用方法を説明する。
すなわち、まず被検者は上体を起こした状態で首部に輪体４を装着する（図３）。この際、輪体４の径が首まわりにちょうど合うように輪体４の径を調節する。その後、クリップ６を被検者の衣服の襟元付近に挟み込んで輪体４が自由に回転しないようにした上で、被検者は横たわり（横臥状態となり）入眠する。
輪体４の首部に対する角度、つまり転倒検出スイッチ３の位置はクリップを所定の位置（衣服の襟元正面）に挟みさえすれば、ちょうど適正な位置になるように予め設定しておく。
上記のようにした上で、図示しない電源を入れ、前記電気回路７、データ収集装置１１などを作動させれば、データ収集装置１１に睡眠中の人体の向きのデータが収集される。
なお、転倒検出スイッチに匹敵するような低価格で取扱いやすい半導体センサーが将来出現すれば、上記実施形態の転倒検出スイッチに代えてそれらを用いることが可能である。 Next, the method of use will be described by taking an example in the diagnosis of sleep apnea syndrome.
That is, first, the subject wears the ring body 4 at the neck with the upper body raised (FIG. 3). At this time, the diameter of the ring body 4 is adjusted so that the diameter of the ring body 4 just fits around the neck. Thereafter, the clip 6 is sandwiched near the collar of the subject's clothes so that the ring body 4 does not rotate freely, and the subject lies down (becomes lying down) and falls asleep.
The angle of the ring body 4 with respect to the neck, that is, the position of the fall detection switch 3 is set in advance so as to be an appropriate position as long as the clip is sandwiched between the predetermined positions (the front of the collar of the clothes).
If the power supply which is not shown in figure is turned on and the said electric circuit 7, the data collection device 11, etc. are operated after doing as mentioned above, the data of the direction of the human body in sleep will be collected by the data collection device 11.
If semiconductor sensors that are inexpensive and easy to handle comparable to the fall detection switch will appear in the future, they can be used in place of the fall detection switch of the above embodiment.

以上のように輪体のおおよその角度を検出することができるので、横臥状態の人体の向きを検出して睡眠時無呼吸症候群の診断に利用できるほか、睡眠時の動きをモニターすることが必要な種々の研究や、実験などに利用できる。 As described above, the approximate angle of the annulus can be detected, so it can be used for diagnosis of sleep apnea syndrome by detecting the orientation of the lying human body, and it is necessary to monitor the movement during sleep It can be used for various researches and experiments.
