[0035] 本発明は以下の効果を奏する。 [0035] The present invention has the following effects.
[0036] [1]の発明では、シーツ本体の内部における被験者の被験部位に対応する位置に 、起歪板がシーツ本体に対して固定された状態で配置されているので、被験者の体 動などにより生じることのある起歪板の位置ずれを防止できる。そのため、生体情報 の計測の開始時から終了時までの間に亘つて生体情報を正確に計測することができ る。  [0036] In the invention of [1], the strain plate is arranged in a state corresponding to the test site of the subject within the sheet body in a state of being fixed with respect to the sheet body. It is possible to prevent the displacement of the strain generating plate that may occur due to the above. For this reason, the biological information can be accurately measured from the start to the end of the measurement of the biological information.
[0037] [2]の発明では、起歪板の幅方向中間部の長さが、起歪板の幅方向両端部の長さ よりも短く設定されているので、被験者が起歪板の幅方向中間部に位置した場合は もとより、被験者が起歪板の幅方向端部に位置した場合であっても、起歪板の幅方 向中間部に歪みが集中的に生じる。起歪板のこのような部位に歪み検出センサが装 着されることにより、被験者が起歪板の幅方向中間部に位置している場合はもとより、 被験者が起歪板の幅方向端部に位置している場合であっても、歪み検出センサから の出力信号の強度低下を抑制できる。 [0038] さらに、起歪板の様々な部位のうち幅方向中間部だけに歪み検出センサを装着す ることで、上記の効果を得られるから、シーツの構造の簡素化を図ることができる。 [0037] In the invention of [2], the length of the intermediate portion in the width direction of the strain generating plate is set to be shorter than the length of both ends in the width direction of the strain generating plate. In addition to being located in the middle part of the direction, strain is intensively generated in the middle part in the width direction of the strain plate even if the subject is located at the end in the width direction of the strain plate. By installing the strain detection sensor at such a portion of the strain generating plate, the test subject is positioned at the width direction end of the strain generating plate as well as when the subject is located in the middle portion of the strain generating plate in the width direction. Even if it is located, it is possible to suppress a decrease in the intensity of the output signal from the strain detection sensor. [0038] Furthermore, since the above-described effect can be obtained by attaching the strain detection sensor only to the intermediate portion in the width direction among various portions of the strain generating plate, the structure of the sheet can be simplified.
[0039] [3]及び [4]の発明では、上記の効果を確実に奏し得る。 [0039] In the inventions [3] and [4], the above-described effects can be reliably obtained.
[0040] [5]の発明では、起歪板の周縁部に、該周縁部を覆うエッジカバーが装着されてい るので、起歪板の周縁部に被験者の身体が当たることによる被験者の痛みを軽減で きる。また、もし仮にシーツ本体の内部に弾性シートが配置されている場合には、起 歪板の周縁部で弾性シートが切断される不具合をエッジカバーによって防止できる。  [0040] In the invention of [5], since the edge cover that covers the peripheral portion is attached to the peripheral portion of the strain generating plate, the pain of the subject due to the subject's body hitting the peripheral portion of the strain generating plate is prevented. Can be reduced. Further, if an elastic sheet is disposed inside the sheet body, the edge cover can prevent the elastic sheet from being cut at the peripheral edge of the strain plate.
[0041] [6]の発明では、起歪板の周縁部にエッジカバーを強固に装着することができる。  In the invention of [6], the edge cover can be firmly attached to the peripheral edge portion of the strain generating plate.
さらに、起歪板の周縁部に被験者の身体が当たることによる被験者の痛みを確実に 軽減できる。  Furthermore, the pain of the subject due to the subject's body hitting the peripheral edge of the strain plate can be reliably reduced.
[0042] [7]の発明では、エッジカバーを安価に製作できる。さらに、榭脂製のエッジカバー は一般に適度な弾性を有して 、るので、起歪板の周縁部にエッジカバーを装着する ことに伴う歪み検出精度の低下を防止できる。  [0042] In the invention of [7], the edge cover can be manufactured at low cost. Further, since the edge cover made of resin generally has appropriate elasticity, it is possible to prevent a decrease in strain detection accuracy caused by mounting the edge cover on the peripheral edge of the strain generating plate.
[0043] [8]の発明では、起歪板の上面に第 1弾性層が配置されていることから、第 1弾性 層によって被験者に対して柔ら力感を与えることができる。  [0043] In the invention of [8], since the first elastic layer is disposed on the upper surface of the strain generating plate, the first elastic layer can give a soft feeling to the subject.
[0044] さらに、起歪板の下面に第 2弾性層が配置されているから、起歪板が確実に橈曲し 得て、該起歪板に歪みを確実に生じさせることができる。  [0044] Furthermore, since the second elastic layer is disposed on the lower surface of the strain generating plate, the strain generating plate can be surely bent, and the strain generating plate can be reliably distorted.
[0045] さらに、第 2弾性層の下面に剛性層が配置されているので、寝床面の硬さが起歪板 の歪み量に与える影響を緩和することができる。これにより、寝床面の硬さに依らない で起歪板の歪みを確実に検出することができ、もって生体情報を正確に計測すること ができる。したがって、このシーツを、寝床面として、例えばベッドのマットレスの上面 等の柔らかい面の上に載置して計測を行う場合であっても、あるいは、例えば床板面 や畳面等の硬!、面の上に載置して計測を行う場合であっても、生体情報を正確に計 測することができる。さらに、寝床面が平坦面である場合はもとより、寝床面が不陸面 である場合であっても、生体情報を正確に計測することができる。  [0045] Further, since the rigid layer is disposed on the lower surface of the second elastic layer, the influence of the hardness of the bed surface on the strain amount of the strain-generating plate can be mitigated. As a result, it is possible to reliably detect the strain of the strain generating plate without depending on the hardness of the bed surface, and thus it is possible to accurately measure biological information. Therefore, even when the sheet is placed on a soft surface such as an upper surface of a bed mattress, for example, as a bed surface, measurement is performed, or a hard surface such as a floor plate surface or a tatami surface is used. Biological information can be accurately measured even when it is placed on and measured. Furthermore, the biological information can be accurately measured not only when the bed surface is a flat surface but also when the bed surface is a non-land surface.
[0046] [9]の発明では、第 1弾性層は、 日本工業規格 JIS K 6401による硬さ 20〜200 N、及び厚さ 3〜: LOmmのウレタンフォーム材から形成されることにより、被験者に対 して柔ら力感を確実に与えることができる。 [0047] [10]の発明では、第 2弾性層は、 日本工業規格 JIS K 6401による硬さ 150〜3 OON、及び厚さ 3〜15mmのウレタンフォーム材から形成されることにより、起歪板の 下方向への橈曲による該起歪板の剛性層への当接を防止することができる。これに より、起歪板が更に確実に橈曲し得て、該起歪板に歪みを更に確実に生じさせること ができる。 [0046] In the invention of [9], the first elastic layer is formed of a urethane foam material having a hardness of 20 to 200 N and a thickness of 3 to: LOmm according to Japanese Industrial Standard JIS K 6401. In contrast, it is possible to give a soft feeling of strength. [0047] In the invention of [10], the second elastic layer is formed of a urethane foam material having a hardness of 150 to 3 OON and a thickness of 3 to 15 mm according to Japanese Industrial Standard JIS K 6401. It is possible to prevent the strain plate from coming into contact with the rigid layer by bending downward. As a result, the strain plate can bend more reliably, and the strain plate can be more surely strained.
[0048] [11]の発明では、剛性層は、曲げこわさが起歪板の曲げこわさに対して 2倍以上 に設定されることにより、寝床面の硬さに依らないで起歪板の歪みを更に確実に検出 することができ、もって生体情報を更に正確に計測することができる。  [0048] In the invention of [11], the rigid layer is set so that the bending stiffness is set to at least twice the bending stiffness of the strain-generating plate, so that the strain of the strain-generating plate does not depend on the hardness of the bed surface. Can be detected more reliably, and biological information can be measured more accurately.
[0049] [12]の発明では、シーツ本体の上面に、被験者の適切な就寝位置を示す人型の マークが付されているので、この人型マークに合うように被験者がシーツ本体上で横 になることにより、起歪板を被験者の被験部位の下側に確実に配置させることができ る。これにより、被験者の被験部位力もの生体情報を確実に計測することができる。  [0049] In the invention of [12], a humanoid mark indicating an appropriate sleeping position of the subject is attached to the upper surface of the sheet body. As a result, the strain plate can be surely placed below the test site of the subject. As a result, it is possible to reliably measure the biological information of the test site strength of the subject.
[0050] [13]の発明では、シーツ本体が折り畳み可能又は捲回可能であるから、シーツ本 体を使用しないときには、シーツ本体を折り畳んだりシーツ本体をその端部力 捲回 したりすることにより、シーツ本体をコンパクトな状態で保管したり収納したりすることが できる。  [0050] In the invention of [13], since the sheet main body can be folded or wound, when the sheet main body is not used, the sheet main body is folded or the end force of the sheet main body is wound. The sheet body can be stored and stored in a compact state.
[0051] [14]の発明では、起歪板がシーツ本体に対して取外し可能に固定されているので 、被験者の身長に応じて起歪板の固定位置を変更することができる。これにより、起 歪板を被験者の被験部位の下側に確実に配置させることができ、もって被験者の被 験部位からの生体情報を確実に計測することができる。  [0051] In the invention [14], since the strain generating plate is detachably fixed to the sheet body, the fixing position of the strain generating plate can be changed according to the height of the subject. As a result, the strain plate can be reliably placed below the test site of the subject, and thus the biological information from the test site of the test subject can be reliably measured.
[0052] さらに、シーツ本体が汚れた際には、起歪板をシーツ本体に対して取り外して、該 起歪板をシーツ本体の内部から取り出すことにより、シーツ本体を容易に洗浄 (洗濯) することができる。  [0052] Further, when the sheet main body becomes dirty, the strain plate is removed from the sheet main body, and the sheet main body is easily washed (washed) by taking out the strain plate from the inside of the sheet main body. be able to.
[0053] [15]の発明では、起歪板の固定位置を変更する際に、互いに接合された面ファス ナの一方と他方とを分離することにより、起歪板をシーツ本体に対して取り外すことが できる。そのため、起歪板の固定位置を容易に変更することができる。  [0053] In the invention of [15], when the fixing position of the strain generating plate is changed, one of the surface fasteners joined to each other is separated from the other, thereby removing the strain generating plate from the sheet body. be able to. Therefore, the fixing position of the strain generating plate can be easily changed.
[0054] [16]の発明では、起歪板の固定位置を変更する際に、ファスナを開くことにより、 上面シーツ部及び下面シーツ部の周縁部の他部同士を互いに分離することができる 。そのため、起歪板の固定位置を容易に変更することができる。 [0054] In the invention of [16], when changing the fixing position of the strain generating plate, the other portions of the peripheral portions of the upper surface sheet portion and the lower surface sheet portion can be separated from each other by opening the fastener. . Therefore, the fixing position of the strain generating plate can be easily changed.
[0055] [17]の発明では、シーツ本体の内部に起歪板が配置されることより生じるシーツ本 体の上面の凹凸を、弾性シートの厚さによって解消することができる。これにより、被 験者に対して寝心地を良くすることができる。  [0055] According to the invention of [17], the unevenness of the upper surface of the sheet main body caused by disposing the strain generating plate inside the sheet main body can be eliminated by the thickness of the elastic sheet. Thereby, it is possible to improve the sleeping comfort for the subject.
[0056] [18]の発明では、被験者の頭部、胸部及び腹部からの生体情報をそれぞれ独立 して計測することができる。これにより、より詳細な生体情報を計測できる。 [0056] In the invention of [18], biological information from the head, chest and abdomen of the subject can be measured independently. Thereby, more detailed biological information can be measured.
[0057] [19]の発明では、シーツ本体の内部に、歪み検出センサの動作電源が配置され ているので、外部電源を用いなくても歪み検出センサにその動作電力を供給できる。 [0057] In the invention of [19], since the operation power source of the strain detection sensor is arranged inside the sheet main body, the operation power can be supplied to the strain detection sensor without using an external power source.
[0058] [20]の発明では、シーツ本体の内部に、歪み検出センサ力 の出力信号を制御 する制御手段が配置されているので、外部の制御手段を用いなくても歪み検出セン サからの出力信号を制御できる。 [0058] In the invention of [20], since the control means for controlling the output signal of the strain detection sensor force is arranged inside the sheet main body, there is no need to use an external control means.

The upper surface sheet portion (3) and the lower surface sheet portion (4) are overlapped with each other to form the sheet body (2).
[0073] このシーツ本体(2)の構成について詳述すると次のとおりである。 [0073] The configuration of the sheet body (2) is described in detail as follows.
[0074] 図 6に示すように、このシーツ本体(2)は、柔軟な布や合成樹脂(ポリエチレン、ポリ プロピレン、ポリ塩ィ匕ビュル等)製の一枚のシート材カも形成されたものであって、該 シート材が二つに折られるとともに、該二つ折り状のシート材の一方の半部が上面シ ーッ部(3)とされるとともに、他方の半部が下面シーツ部 (4)とされたものである。した がって、上面シーツ部(3)及び下面シーツ部 (4)の周縁部のうち右側縁部同士は一 体に連結されており、一方、上面シーツ部(3)及び下面シーツ部 (4)の周縁部のうち 頭側の縁部同士、左側縁部同士、及び足側の縁部同士は、これらの縁部に固着 (詳 述すると縫着)されたファスナ(12)によって分離可能に結合されている(図 1参照)。 なお(12a)は、このファスナ(12)の引手である。 [0074] As shown in Fig. 6, the sheet body (2) is also formed with a single sheet material cover made of a flexible cloth or a synthetic resin (polyethylene, polypropylene, polysalt gel, etc.). And the The sheet material is folded in half, and one half of the folded sheet material is the upper surface sheet (3) and the other half is the lower surface sheet (4). It is. Therefore, the right side edges of the peripheral portions of the upper surface sheet portion (3) and the lower surface sheet portion (4) are connected together, while the upper surface sheet portion (3) and the lower surface sheet portion (4 ) Can be separated by fasteners (12) fastened to these edges (sewn and sewn in detail).

[0075] また、シーツ本体(2)は、二つ折りや三つ折り等に折り畳み可能なものであり、更に 、該シーツ本体(2)の一端力も丸く捲回可能なものである。  [0075] The sheet body (2) can be folded in two or three, and the one end force of the sheet body (2) can also be rolled round.
[0076] シーツ本体(2)の長さは例えば 1800〜2300mmの範囲内に設定されている。シ ーッ本体(2)の幅は例えば 600〜1300mm (好ましくは 600〜850mm)の範囲内 に設定されて!、る。シーツ本体(2)の上面シーツ部(3)及び下面シーツ部 (4)の厚さ はそれぞれ 0. 3〜0. 5mmの範囲内に設定されている。  [0076] The length of the sheet body (2) is set within a range of 1800 to 2300 mm, for example. The width of the sheet body (2) is set within a range of, for example, 600 to 1300 mm (preferably 600 to 850 mm)! The thickness of the top sheet (3) and bottom sheet (4) of the sheet body (2) is set in the range of 0.3 to 0.5 mm.
[0077] ただし本発明では、シーツ本体(2)の大きさ (長さ、幅、厚さ)は上記の範囲内であ ることに限定されるものではなぐ被験者 (H)の身長やベッド寝床面(52)の大きさ等 に応じて様々に設定されるものである。  [0077] However, in the present invention, the size (length, width, thickness) of the sheet main body (2) is not limited to be within the above-mentioned range. Various settings are made according to the size of the surface (52).
[0078] 3個の起歪板 (5)は互いに同一形状である。起歪板 (5)は、弾性的に橈曲可能なも のであり、図 6に示すように、一方向に延びた平面視長方形状の帯状に形成されて いる。これらの起歪板(5)は、被験者 (H)の各被験部位の下側に 1個ずつ被験者 (H )の幅方向に延びる態様に水平状に配置されるものである。  The three strain generating plates (5) have the same shape. The strain generating plate (5) can be bent elastically, and is formed in a rectangular band shape in plan view extending in one direction as shown in FIG. These strain generating plates (5) are horizontally arranged in a manner extending in the width direction of the subject (H), one below the test site of the subject (H).
[0079] 本第 1実施形態では、被験者 (H)の被験部位の数は 3つであり、被験部位を具体 的に挙げると、被験者 (H)の被験部位は、被験者 (H)の頭部、胸部及び腹部である  [0079] In the first embodiment, the number of test sites of the subject (H) is three. Specifically, the test sites of the test subject (H) are the head of the test subject (H). The chest and abdomen
[0080] 起歪板 (5)は、金属板から形成されており、詳述するとアルミニウム (その合金を含 む。以下同じ。)板から形成されており、板状の押出材ゃ圧延材等からなる。起歪板( 5)がアルミニウム板力も形成されることにより、シーツ(1)の軽量化を図ることができる [0080] The strain generating plate (5) is formed from a metal plate, more specifically, an aluminum plate (including an alloy thereof, the same shall apply hereinafter), and is formed from a plate-like extruded material, rolled material, or the like. Consists of. The sheet plate (1) can be reduced in weight by the fact that the strain generating plate (5) also has aluminum plate force.
[0081] ただし本発明では、起歪板(5)はアルミニウム製であることに限定されるものではな ぐその他に、例えば、鉄、鋼、ステンレス鋼、マグネシウム合金、銅 (その合金を含む 。)製であっても良いし、繊維強化プラスチック等のプラスチック製であっても良い。 However, in the present invention, the strain generating plate (5) is not limited to being made of aluminum. In addition, for example, it may be made of iron, steel, stainless steel, magnesium alloy, copper (including its alloy), or may be made of plastic such as fiber reinforced plastic.
[0082] ここで本明細書では、起歪板(5)の長さ方向とは、被験者 (H)の身長方向に沿う方 向、即ちベッド寝床面(52)の長さ方向に沿う方向である。起歪板(5)の幅方向とは、 被験者 (H)の幅方向に沿う方向であり、即ちベッド寝床面(52)の幅方向に沿う方向 である。  [0082] Here, in this specification, the length direction of the strain generating plate (5) is a direction along the height direction of the subject (H), that is, a direction along the length direction of the bed bed surface (52). is there. The width direction of the strain generating plate (5) is the direction along the width direction of the subject (H), that is, the direction along the width direction of the bed bed surface (52).
[0083] 起歪板(5)の上下両面は平坦状に形成されている。また、起歪板(5)の厚さは、該 起歪板(5)の幅方向及び長さ方向において一定に設定されている。また、起歪板(5 )の長さは、該起歪板(5)の幅方向にお!、て一定に設定されて 、る。  [0083] The upper and lower surfaces of the strain generating plate (5) are formed flat. Further, the thickness of the strain generating plate (5) is set to be constant in the width direction and the length direction of the strain generating plate (5). The length of the strain generating plate (5) is set to be constant in the width direction of the strain generating plate (5).
[0084] ただし本発明では、起歪体(5)の厚さは該起歪板(5)の幅方向及び長さ方向にお いて一定に設定されていることに限定されるものではなぐその他に、例えば、起歪 体 (5)の幅方向中間部の厚さが、該起歪板 (5)の幅方向両端部の厚さよりも薄く設 定されていても良い。  [0084] However, in the present invention, the thickness of the strain generating body (5) is not limited to being set to be constant in the width direction and the length direction of the strain generating plate (5). For example, the thickness of the intermediate portion in the width direction of the strain generating body (5) may be set to be thinner than the thickness of both end portions in the width direction of the strain generating plate (5).
[0085] また本発明では、起歪板(5)の長さは、該起歪板(5)の幅方向において一定に設 定されていることに限定されるものではなぐその他に、例えば、起歪板(5)の幅方向 中間部の長さが、該起歪体 (2)の幅方向両端部の長さよりも短く設定されていても良 い(図 9〜図 11参照)。そのような構成の起歪板にっ 、ては後で説明する。  [0085] In the present invention, the length of the strain generating plate (5) is not limited to being set to be constant in the width direction of the strain generating plate (5). The length of the intermediate portion in the width direction of the strain generating plate (5) may be set shorter than the length of both ends in the width direction of the strain generating body (2) (see FIGS. 9 to 11). The strain generating plate having such a configuration will be described later.
[0086] 起歪板(5)の幅は、例えば 300〜1200mmの範囲内に設定される。起歪板(5)の 長さは、例えば 50〜200mmの範囲内に設定される。このように起歪板(5)の幅及び 長さを設定することにより、被験者 (H)として乳幼児から大人まで起歪板 (5)を適用 することができ、もって被験者 (H)に対する起歪板 (5)の適用範囲が増大する。また 、起歪体(5)の厚さは、例えば 0. 5〜3mmの範囲内に設定される。  [0086] The width of the strain generating plate (5) is set within a range of 300 to 1200 mm, for example. The length of the strain generating plate (5) is set within a range of 50 to 200 mm, for example. By setting the width and length of the strain generating plate (5) in this way, the strain generating plate (5) can be applied as a subject (H) from infants to adults. The range of application of the plate (5) is increased. Further, the thickness of the strain generating body (5) is set within a range of 0.5 to 3 mm, for example.
[0087] ただし本発明では、起歪板(5)の幅、長さ及び厚さは上記の範囲内であることに限 定されるものではない。  However, in the present invention, the width, length, and thickness of the strain generating plate (5) are not limited to be within the above-mentioned range.
[0088] 起歪板(5)の曲げこわさは、例えば 3 X 104〜12 X 108Nmm2の範囲内に設定され る。起歪体(5)の曲げこわさが上記の範囲内に設定されることにより、被験者 (H)の 生体活動に伴い起歪板(5)に歪みが確実に生じたりその歪みが確実に変動したりす るものとなる。ただし本発明では、起歪板(5)の曲げこわさは上記の範囲内であること に限定されるものではない。 [0088] The bending stiffness of the strain generating plate (5) is set, for example, within a range of 3 × 10 4 to 12 × 10 8 Nmm 2 . By setting the bending stiffness of the strain generating body (5) within the above range, the strain plate (5) is surely distorted or fluctuated with the biological activity of the subject (H). It will be sensible. However, in the present invention, the bending stiffness of the strain generating plate (5) is within the above range. It is not limited to.
[0089] なお、被験者 (H)の生体活動としては、呼吸を始め、その他に、脈拍(心拍、拍動) 、体動 (例:寝返り)等が挙げられる。  Note that the biological activity of the subject (H) includes breathing, and in addition, a pulse (heartbeat, pulsation), body movement (eg, turning over), and the like.
[0090] 起歪板(5)は、ヤング率が 1000〜230000MPaの範囲の材料で形成されたもの であることが望ましい。起歪体(2)の材料のヤング率が上記の範囲内に設定されるこ とにより、被験者 (H)の生体活動に伴い起歪板(5)に歪みが確実に生じたりその歪 みが確実に変動したりするものとなる。ただし本発明では、起歪板(5)の材料のヤン グ率は上記の範囲内であることに限定されるものではない。  [0090] The strain generating plate (5) is preferably formed of a material having a Young's modulus in the range of 1000 to 230000 MPa. By setting the Young's modulus of the material of the strain generating body (2) within the above range, the strain generating plate (5) is surely distorted or is distorted due to the biological activity of the subject (H). It will surely fluctuate. However, in the present invention, the Yang rate of the material of the strain generating plate (5) is not limited to be in the above range.
[0091] ここで、 3個の起歪板 (5) (5) (5)のうち、説明の便宜上、被験者 (H)の頭部の下側 に配置されるものを「頭部用起歪板(5)」、被験者 (H)の胸部の下側に配置されるも のを「胸部用起歪板 (5)」、及び、被験者 (H)の腹部の下側に配置されるものを「腹 部用起歪板 (5)」という。頭部用起歪板 (5)、胸部用起歪板 (5)及び腹部用起歪板( 5)は、それぞれ、被験者 (H)の頭部、胸部及び腹部からの生体情報を計測するため に用いられるものである。  Here, among the three strain generating plates (5), (5), and (5), those arranged below the head of the subject (H) for convenience of explanation are referred to as “head strain generating strains”. "Plate (5)", those placed under the chest of the subject (H) "Strain plate for chest (5)" and those placed under the abdomen of the subject (H) It is called “abdominal strain plate (5)”. The head strain plate (5), the chest strain plate (5) and the abdominal strain plate (5) are for measuring biological information from the head, chest and abdomen of the subject (H), respectively. It is used for.
[0092] 各歪み検出センサ(6)は、上述したように起歪板(5)に装着されており、起歪板(5) に生じる歪みと更にその時間変動とを検出するものである。詳述すると、本第 1実施 形態では、歪み検出センサ(6)は、起歪板(5)の幅方向中間部に生じる歪みと更に その時間変動とを検出するものである。また、歪み検出センサ(6)から出力される信 号は、被験者 (H)の生体情報の計測に用いられるものである。  Each strain detection sensor (6) is attached to the strain-generating plate (5) as described above, and detects the strain generated in the strain-generating plate (5) and its time variation. More specifically, in the first embodiment, the strain detection sensor (6) detects a strain generated in the intermediate portion in the width direction of the strain generating plate (5) and further its temporal variation. The signal output from the strain detection sensor (6) is used for measuring the biological information of the subject (H).
[0093] 歪み検出センサ(6)は、 4個の歪みゲージ(7a) (7a) (7b) (7b)力らなる。図 3〜図 5に示すように、これらの歪みゲージ(7a) (7a) (7b) (7b)のうち、 2個の歪みゲージ( 7a) (7a)と残りの 2個の歪みゲージ(7b) (7b)とは、それぞれ、起歪板(5)の幅方向 中間部の上下両面の互いに対向する位置に、接着剤によって貼着されて装着され ている。図 7に示すように、これらの歪みゲージ(7a) (7a) (7b) (7b)は、互いに電気 的に接続されてブリッジ回路 (詳述するとホイートストンブリッジ回路)(8)が形成され ている。すなわち、このブリッジ回路(8)は 4個の歪みゲージ(7a) (7a) (7b) (7b)が 組み込まれて形成されたものである。  The strain detection sensor (6) includes four strain gauges (7a) (7a) (7b) (7b) force. Of these strain gauges (7a) (7a) (7b) (7b), two strain gauges (7a) (7a) and the remaining two strain gauges (7b) ) (7b) is attached and attached by an adhesive at positions opposite to each other on the upper and lower surfaces of the intermediate portion in the width direction of the strain generating plate (5). As shown in FIG. 7, these strain gauges (7a) (7a) (7b) (7b) are electrically connected to each other to form a bridge circuit (more specifically, a Wheatstone bridge circuit) (8). . In other words, the bridge circuit (8) is formed by incorporating four strain gauges (7a) (7a) (7b) (7b).

As a result, both ends in the width direction of each strain generating plate (5) are placed between one (11a) (11a) and the other (l ib) (l ib) of the left and right surface fasteners (11) (11). Thus, the strain generating plates (5) are fixed to the sheet body (2).

[0116] 次に、本第 1実施形態の生体情報計測用シーツ (1)及び生体情報計測装置 (20) を用いて遂行される生体情報計測方法について、以下に説明する。 Next, a biological information measuring method performed using the biological information measuring sheet (1) and the biological information measuring device (20) of the first embodiment will be described below.
[0117] まず、図 1に示すように、シーツ(1)のシーツ本体(2)を、ベッドの寝床面(52)として のマットレス(51)の上面(51a)上にその全面を覆う状態に敷く。  [0117] First, as shown in FIG. 1, the sheet body (2) of the sheet (1) is covered on the upper surface (51a) of the mattress (51) as the bed surface (52) of the bed. Lay down.
[0118] 次いで、このシーツ本体(2)上に被験者 (H)が就寝、休息、検査等のために、人型 マーク(13)に合うように仰臥姿勢で在床する(即ち横になる)。すると、被験者 (H)の 頭部、胸部及び腹部の重量 (荷重)によってシーツ本体 (2)の各起歪板 (5)が弾性 的に僅かに下方向に断面略円弧状に橈曲する。これにより、各起歪板 (5)に曲げ歪 みが発生し、特に各起歪板(5)の幅方向中間部に曲げ歪みが集中的に発生する。 [0118] Next, on this sheet body (2), the subject (H) is humanoid for sleeping, resting, testing, etc. Be in a supine position (ie, lie down) so that it matches the mark (13). Then, due to the weight (load) of the head, chest and abdomen of the subject (H), each strain plate (5) of the sheet main body (2) is elastically bent in a substantially circular arc shape in a slightly downward direction. As a result, bending strain is generated in each strain generating plate (5), and particularly, bending strain is intensively generated in the intermediate portion in the width direction of each strain generating plate (5).
[0119] 被験者 (H)が就寝 (睡眠)すると、各起歪板 (5)の歪みが被験者 (H)の就寝中の生 体活動 (例:呼吸、拍動)に伴い時間的に微細に変動する。このような時間的な変動 力 各ブリッジ回路(8)により検出される。そして、この各ブリッジ回路(8)からの出力 信号 (出力電圧)が出力信号線 (9b)を介して演算手段 (21)に送信される。そして、 こうして送信された信号に基づいて演算手段(21)により被験者 (H)の生体情報が演 算される。 [0119] When subject (H) goes to bed (sleeps), the strain on each strain plate (5) becomes finer in time with the biological activity (eg, breathing, pulsation) during sleep of subject (H). fluctuate. Such temporal fluctuation force is detected by each bridge circuit (8). The output signal (output voltage) from each bridge circuit (8) is transmitted to the computing means (21) via the output signal line (9b). Based on the signal thus transmitted, the biological information of the subject (H) is calculated by the calculation means (21).
[0120] 演算手段(21)の演算結果としての被験者 (H)の生体情報は、通信手段(22)によ り演算手段(21)から報知手段(23)に送信され、報知手段(23)により報知対象者に 対して報知される。これにより、報知対象者は被験者 (H)の生体情報を知ることがで きる。  [0120] The biological information of the subject (H) as the calculation result of the calculation means (21) is transmitted from the calculation means (21) to the notification means (23) by the communication means (22), and the notification means (23) Is notified to the target person. As a result, the person to be notified can know the biological information of the subject (H).
[0121] 而して、本第 1実施形態の生体情報計測用シーツ(1)は次の利点がある。  Therefore, the biological information measuring sheet (1) of the first embodiment has the following advantages.
[0122] すなわち、このシーツ(1)によれば、シーツ本体(2)の内部における被験者 (H)の 各被験部位に対応する位置に、起歪板(5)がシーツ本体(2)に対して固定された状 態で配置されて 、るので、被験者 (H)の体動 (例:寝返り)などにより生じることのある 起歪板 (5)の位置ずれを防止できる。そのため、生体情報の計測の開始時から終了 時までの間に亘つて生体情報を正確に計測することができる。  [0122] That is, according to the sheet (1), the strain plate (5) is located at a position corresponding to each test site of the subject (H) inside the sheet body (2) with respect to the sheet body (2). Therefore, it is possible to prevent the displacement of the strain generating plate (5) that may be caused by body movement (eg, turning over) of the subject (H). Therefore, the biological information can be accurately measured from the start to the end of the measurement of the biological information.
[0123] さらに、シーツ本体(2)の上面に、被験者 (H)の適切な就寝位置を示す人型のマ ーク( 13)が付されて 、るので、この人型マーク( 13)に合うように被験者 (H)がシー ッ本体 (2)上で横になることにより、被験者 (H)の各被験部位の下側に、対応する起 歪板(5)を確実に配置させることができる。これにより、被験者 (H)の各被験部位から の生体情報を確実に計測することができる。  [0123] Furthermore, a humanoid mark (13) indicating an appropriate sleeping position of the subject (H) is attached to the upper surface of the sheet body (2). When the subject (H) lies on the seat body (2) so as to fit, the corresponding strain plate (5) can be surely placed under each test site of the subject (H). it can. Thereby, the biological information from each test site of the subject (H) can be reliably measured.
[0124] さらに、シーツ本体(2)が折り畳み可能又は捲回可能であるから、シーツ本体(2)を 使用しないときには、シーツ本体 (2)を折り畳んだりシーツ本体 (2)をその端部力も捲 回したりすることにより、シーツ本体 (2)をコンパクトな状態で保管したり収納したりす ることがでさる。 [0124] Further, since the sheet main body (2) can be folded or rolled, when the sheet main body (2) is not used, the sheet main body (2) can be folded or the end of the sheet main body (2) can be reduced. The sheet body (2) can be stored and stored in a compact state by turning it. It can be done.
[0125] さらに、各起歪板(5)がシーツ本体(2)に対して取外し可能に固定されているので 、被験者 (H)の身長に応じて各起歪板 (5)の固定位置を変更することができる。これ により、被験者 (H)の各被験部位の下側に、対応する起歪板(5)を確実に配置させ ることができ、もって被験者 (H)の各被験部位力もの生体情報を更に確実に計測す ることがでさる。  [0125] Furthermore, since each strain plate (5) is detachably fixed to the sheet body (2), the position of each strain plate (5) is fixed according to the height of the subject (H). Can be changed. As a result, the corresponding strain generating plate (5) can be surely placed below each test site of the subject (H), and thus the biological information of the test site (H) can be more reliably obtained. It is possible to measure it.
[0126] さらに、シーツ本体(2)が汚れた際には、各起歪板(5)をシーツ本体(2)に対して 取り外して、該起歪板(5)をシーツ本体(2)の内部力 取り出すことにより、シーツ本 体 (2)を容易に洗浄 (洗濯)することができる。  [0126] Further, when the sheet body (2) is soiled, each strain plate (5) is removed from the sheet body (2), and the strain plate (5) is removed from the sheet body (2). By taking out the internal force, the sheet body (2) can be easily washed (washed).
[0127] また、このシーツ(1)によれば、シーツ本体(2)の上面シーツ部(3)と下面シーツ部  [0127] Further, according to the sheet (1), the upper surface sheet portion (3) and the lower surface sheet portion of the sheet body (2).
(4)とが重ね合わされた状態にお!、て、左右両方の面ファスナ(11) (11)の一方(11 a) (11a)と他方(l ib) (l ib)との間で各起歪板 (5)の幅方向両端部を挟んだ状態 で左右両方の面ファスナ(11) (11)の一方(11a) (11a)と他方(l ib) (l ib)とが互 いに分離可能に接合されることにより、各起歪板 (5)がシーツ本体 (2)に対して取外 し可能に固定されている。したがって、各起歪板(5)の固定位置を変更する際に、互 いに接合された左右両方の面ファスナ(11) (11)の一方(11a) (11a)と他方(l ib) ( l ib)とを分離することにより、各起歪板 (5)をシーツ本体 (2)に対して取り外すことが できる。そのため、各起歪板(5)の固定位置を容易に変更することができる。  (4) and the left and right hook-and-loop fasteners (11) and (11) between one (11 a) (11a) and the other (l ib) (l ib) One side (11a) (11a) and the other side (l ib) (l ib) of both the left and right hook-and-loop fasteners (11) and (11) with both ends in the width direction of the strain generating plate (5) sandwiched Each strain generating plate (5) is detachably fixed to the sheet body (2) by being separably joined. Therefore, when changing the fixed position of each strain generating plate (5), one (11a) (11a) of the left and right surface fasteners (11) (11) and the other (l ib) ( l By separating ib), each strain plate (5) can be removed from the sheet body (2). Therefore, the fixing position of each strain generating plate (5) can be easily changed.
[0128] さらに、シーツ本体(2)の内部における各起歪板(5)の配置位置以外の位置に弹 性シート(10)が配置されて 、るので、シーツ本体(2)の内部に各起歪板(5)が配置 されることより生じるシーツ本体(2)の上面の凹凸を、弾性シート(10)の厚さによって 解消することができる。これにより、被験者 (H)に対して寝心地を良くすることができる  [0128] Further, the elastic sheet (10) is arranged at a position other than the arrangement position of each strain generating plate (5) inside the sheet main body (2). Unevenness on the upper surface of the sheet main body (2) caused by the placement of the strain generating plate (5) can be eliminated by the thickness of the elastic sheet (10).

Since the chest strain plate (5) and the abdomen strain plate (5) disposed below the abdomen of the subject (H) are provided, the head, chest and Biological information from the abdomen can be measured independently. Thereby, more detailed biological information can be measured. Therefore, a biological information meter provided with this sheet (1) According to the measurement device (20), detailed biological information of the subject (H) includes, for example, obstructive sleep apnea syndrome (OSAS), central sleep apnea syndrome (CSAS), and mixed sleep apnea.

Are separably connected by. Therefore, when changing the fixing position of each strain generating plate (5), the edges of the upper surface sheet portion (3) and the lower surface sheet portion (4) are separated from each other by opening the fastener (12). be able to. Therefore, the fixed position of each strain generating plate (5) can be easily changed.

[0141] 図 9及び図 10は、本発明の第 2実施形態に係る生体情報計測用シーツの起歪板 を説明する図である。本第 2実施形態のシーツの構成について上記第 1実施形態と 相異する点を中心に以下に説明する。  [0141] Figs. 9 and 10 are diagrams for explaining a strain-generating plate of a biological information measuring sheet according to the second embodiment of the present invention. The configuration of the sheet of the second embodiment will be described below with a focus on differences from the first embodiment.
[0142] 本第 2実施形態では、起歪板 (5)の長さ方向両端縁 (5a) (5a)は、それぞれ、その 全長に亘つて起歪板 (5)の内側に凹んだ円弧状に形成されている。これにより、起歪 板(5)の幅方向中間部の長さ L1は、起歪板(5)の幅方向両端部の長さ LOよりも短く 設定されて ヽる(即ち、 LI < LO)。  [0142] In the second embodiment, both ends (5a) and (5a) in the longitudinal direction of the strain generating plate (5) are arcuate indented inside the strain generating plate (5) over the entire length thereof. Is formed. As a result, the length L1 of the intermediate portion in the width direction of the strain generating plate (5) is set to be shorter than the length LO of both ends in the width direction of the strain generating plate (5) (that is, LI <LO). .
[0143] 起歪板(5)の幅方向各端部の長さ LOは、例えば 50〜200mmの範囲に設定され るのが望ましい。起歪板(5)の幅方向中間部の長さ L1は、 LOに対して例えば 0. 3〜 0. 8倍の範囲に設定されるのが望ましい(即ち、 LlZLO = 0. 3〜0. 8が望ましい)。 起歪板(5)の幅 Wは、例えば 300〜1200mmの範囲に設定されるのが望ましい。 W が上記の範囲に設定されることにより、被験者 (H)として乳幼児から大人まで起歪板 (5)を適用することができ、もって被験者 (H)に対するシーツ(1)の適用範囲が増大 する。起歪板(5)の厚さは、例えば 0. 5〜3mmの範囲に設定されるのが望ましい。  [0143] The length LO of each end in the width direction of the strain generating plate (5) is preferably set in the range of 50 to 200 mm, for example. The length L1 of the intermediate portion in the width direction of the strain generating plate (5) is preferably set in a range of, for example, 0.3 to 0.8 times LO (that is, LlZLO = 0.3 to 0. 0). 8 is preferred). The width W of the strain generating plate (5) is preferably set in the range of 300 to 1200 mm, for example. By setting W to the above range, the strain plate (5) can be applied from infants to adults as the subject (H), and thus the application range of the sheet (1) to the subject (H) is increased. . The thickness of the strain generating plate (5) is preferably set in the range of 0.5 to 3 mm, for example.
[0144] 起歪板(5)の各部位の寸法が上記の範囲に設定されることにより、被験者 (H)の生 体活動に伴い起歪板(5)に歪みが確実に生じたりその歪みが確実に変動したりする ものとなる。ただし本発明では、起歪板(5)の各部位の寸法は上記の範囲であること に限定されるものではない。 [0144] By setting the dimensions of each part of the strain-generating plate (5) within the above range, the strain-generating plate (5) is surely distorted due to the biological activity of the subject (H), or the strain is generated. Will surely fluctuate. However, in the present invention, the dimension of each part of the strain generating plate (5) is within the above range. It is not limited to.
[0145] なお、(5b)は、起歪板(5)の歪みゲージ装着部の近傍に設けられ、入力信号線 (9 a)及び出力信号線 (9b)が挿通される小孔である。  Note that (5b) is a small hole provided in the vicinity of the strain gauge mounting portion of the strain generating plate (5) and through which the input signal line (9a) and the output signal line (9b) are inserted.
[0146] 本第 2実施形態のシーツの他の構成は、上記第 1実施形態と同じである。  [0146] Other configurations of the sheet of the second embodiment are the same as those of the first embodiment.
[0147] 而して、本第 2実施形態の生体情報計測用シーツ(1)は次の利点がある。  Accordingly, the biological information measuring sheet (1) of the second embodiment has the following advantages.
[0148] 起歪板(5)の幅方向中間部の長さ L1が、起歪板(5)の幅方向両端部の長さ LOより も短く設定されて 、るので、被験者 (H)が起歪板(5)の幅方向中間部に位置した場 合はもとより、被験者 (H)が起歪板 (5)の幅方向端部に位置した場合であっても、起 歪板(5)の幅方向中間部に歪みが集中的に生じる。起歪板(5)のこのような部位に 歪み検出センサ(6)が装着されて!、るので、被験者 (H)が起歪板 (5)の幅方向中間 部に位置して 、る場合はもとより、被験者 (H)が起歪板(5)の幅方向端部に位置して いる場合であっても、歪み検出センサ(6)からの出力信号の強度低下を抑制できる。  [0148] Since the length L1 of the intermediate portion in the width direction of the strain generating plate (5) is set to be shorter than the length LO of both ends in the width direction of the strain generating plate (5), the subject (H) Even if the subject (H) is located at the end of the strain plate (5) in the width direction, the strain plate (5) Distortion is intensively generated at the intermediate portion in the width direction. The strain detection sensor (6) is attached to such a portion of the strain generating plate (5)! Therefore, when the subject (H) is located in the middle portion in the width direction of the strain generating plate (5) Of course, even when the subject (H) is located at the end in the width direction of the strain generating plate (5), it is possible to suppress a decrease in the intensity of the output signal from the strain detection sensor (6).
[0149] さらに、起歪板 (5)の製造用素材として、安価に入手可能な、厚さが一定の平板材 を用い、この平板材力 起歪板 (5)を打抜き加工等によって製作できる。したがって、 起歪板 (5)を容易に且つ安価に製作できる。  [0149] Further, as a material for producing the strain generating plate (5), a flat plate material having a constant thickness that can be obtained at low cost can be used, and the plate material force generating plate (5) can be manufactured by punching or the like. . Therefore, the strain generating plate (5) can be manufactured easily and inexpensively.
[0150] さらに、このシーツ(1)では、起歪板(5)の様々な部位のうち幅方向中間部だけに 歪み検出センサ(6)を装着することで、上記の効果を得られるから、シーツ(1)の構 造の簡素化を図ることができる。  [0150] Further, in the sheet (1), the above-described effect can be obtained by attaching the strain detection sensor (6) only to the intermediate portion in the width direction among various portions of the strain generating plate (5). The structure of the sheet (1) can be simplified.
[0151] さらに、起歪板(5)の長さ方向両端縁 (5a) (5a)が、それぞれ、その全長に亘つて 起歪板(5)の内側に凹んだ円弧状に形成されているので、上記の効果を確実に奏し うる。  [0151] Further, both end edges (5a) and (5a) in the longitudinal direction of the strain generating plate (5) are formed in an arc shape that is recessed inside the strain generating plate (5) over the entire length thereof. Therefore, the above effect can be surely achieved.
[0152] なお、第 2実施形態では、起歪板 (5)の長さ方向両端縁 (5a) (5a)の両方がそれぞ れ円弧状に形成されているが、本発明では、その他に、例えば、起歪板 (5)の長さ方 向両端縁 (5a) (5a)のうち ヽずれか一方だけが円弧状に形成されて!ヽても良!ヽ。  [0152] In the second embodiment, both end edges (5a) (5a) in the length direction of the strain generating plate (5) are each formed in an arc shape. For example, only one of the longitudinal end edges (5a) and (5a) of the strain plate (5) may be formed in an arc shape.
[0153] また本発明では、起歪板(5)の上下両面のうち少なくとも上面に、弾性シート材から なる弾性層(図示せず)が設けられていても良い。この場合には、被験者 (H)に対し て柔ら力感を与えることができる。そのため、被験者 (H)において寝心地が良くなる。  [0153] In the present invention, an elastic layer (not shown) made of an elastic sheet material may be provided on at least the upper surface of the upper and lower surfaces of the strain generating plate (5). In this case, a soft feeling can be given to the subject (H). Therefore, the subject (H) is comfortable in sleeping.

[0155] 本第 3実施形態では、起歪板 (5)は、その長さ方向両端縁 (5a) (5a)の幅方向中 間部に、それぞれ、起歪板 (5)の内側に略コ字状 (コ字状)に局部的に凹んだ凹部( 5c) (5c)が形成されている。これにより、起歪板(5)の幅方向中間部の長さ L1が起 歪板(5)の幅方向両端部の長さ LOよりも短く設定されて 、る。凹部(5c)の幅 W1は 例えば 50〜200mmの範囲に設定されている。ただし本発明では、 W1は上記の範 囲であることに限定されるものではない。  [0155] In the third embodiment, the strain-generating plate (5) is substantially disposed inside the strain-generating plate (5) at the widthwise intermediate portions of both longitudinal edges (5a) (5a). A concave portion (5c) (5c) that is locally recessed in a U-shape (U-shape) is formed. Thus, the length L1 of the intermediate portion in the width direction of the strain generating plate (5) is set to be shorter than the length LO of both ends in the width direction of the strain generating plate (5). The width W1 of the recess (5c) is set in the range of 50 to 200 mm, for example. However, in the present invention, W1 is not limited to the above range.
[0156] なお本発明では、その他に、起歪板(5)の長さ方向両端縁 (5a) (5a)の幅方向中 間部のうちいずれか一方だけに凹部(5c)が形成されていても良い。また本発明では 、凹部(5c)の形状は略コ字状であることに限定されるものではなぐその他に、例え ば円弧状であっても良いし、その他の形状であつても良い。  [0156] In the present invention, in addition, the concave portion (5c) is formed only in one of the widthwise intermediate portions of the longitudinal ends (5a) (5a) of the strain generating plate (5). May be. In the present invention, the shape of the recess (5c) is not limited to being substantially U-shaped, but may be, for example, an arc shape or other shapes.

[0158] 本第 3実施形態のシーツの利点は、上記第 2実施形態と同じである。  [0158] The advantages of the sheet of the third embodiment are the same as those of the second embodiment.
[0159] 図 12〜図 16は、本発明の第 4実施形態に係る生体情報計測用シーツの起歪板を 説明する図である。本第 4実施形態のシーツの構成について上記第 1実施形態と相 異する点を中心に以下に説明する。  FIG. 12 to FIG. 16 are diagrams for explaining a strain generating plate of the biological information measuring sheet according to the fourth embodiment of the present invention. The configuration of the sheet according to the fourth embodiment will be described below with a focus on differences from the first embodiment.
[0160] 本第 4実施形態では、起歪板(5)の周縁部 (5d)には、該周縁部 (5d)を覆うエッジ カバー(15) 1S 該周縁部 (5d)の全周に亘つて装着されて 、る(図 16参照)。  [0160] In the fourth embodiment, the peripheral edge (5d) of the strain generating plate (5) has an edge cover (15) that covers the peripheral edge (5d) 1S over the entire circumference of the peripheral edge (5d). Attached (see Fig. 16).
[0161] このエッジカバー(15)は、ポリ塩化ビュル、ポリウレタン等の榭脂製であり、弾性( 詳述すると曲げ弾性)を有する柔軟なものである。  [0161] The edge cover (15) is made of a resin such as polychlorinated bur and polyurethane, and is flexible and has elasticity (specifically, bending elasticity).
[0162] このエッジカバー(15)は、図 16に示すように断面略円形状(円形状)に形成されて いる。さらに、このエッジカバー(15)の周面部の一部に、エッジカバー(15)の断面 の中心部に向かって凹んだ断面コ字状の嵌合用溝部(15a)が起歪板 (5)の周縁部 (5d)に沿って延設されている。そして、この溝部(15a)内に起歪板(5)の周縁部(5d )が嵌合された状態でエッジカバー(15)が起歪板 (5)の周縁部 (5d)に装着されて いる。本第 4実施形態では、エッジカバー(15)は、起歪板(5)の周縁部(5d)カも不 本意に外れないようにするため、起歪板(5)の周縁部(5d)に接着剤により貼着され て装着されている。 [0162] The edge cover (15) has a substantially circular cross section (circular shape) as shown in FIG. Further, a part of the peripheral surface of the edge cover (15) has a U-shaped fitting groove (15a) recessed toward the center of the cross section of the edge cover (15). It extends along the periphery (5d). Then, the edge cover (15) is mounted on the peripheral edge (5d) of the strain generating plate (5) with the peripheral edge (5d) of the strain generating plate (5) fitted in the groove (15a). Yes. In the fourth embodiment, the edge cover (15) is arranged so that the peripheral edge (5d) of the strain generating plate (5) is not unintentionally removed. Adhered with adhesive Is installed.
[0163] このエッジカバー(15)の直径は、例えば起歪板(5)の厚さよりも 2〜10mm大きく 設定されていることが望ましい。ただし本発明では、エッジカバー(15)の直径は上記 の範囲内であることに限定されるものではない。  [0163] The diameter of the edge cover (15) is preferably set to be 2 to 10 mm larger than the thickness of the strain generating plate (5), for example. However, in the present invention, the diameter of the edge cover (15) is not limited to being in the above range.
[0164] また、起歪板 (5)の左側部と右側部とにそれぞれ歪み検出センサ(6)が装着されて いる。各歪み検出センサ(6)は、上記第 1実施形態と同様に、 4個の歪みゲージ(7a) (7a) (7b) (7b)からなる。そして、これらの歪みゲージ(7a) (7a) (7b) (7b)は、互い に電気的に接続されてブリッジ回路(8)が形成されている。  [0164] Further, a strain detection sensor (6) is attached to each of the left side and the right side of the strain generating plate (5). Each strain detection sensor (6) is composed of four strain gauges (7a) (7a) (7b) (7b) as in the first embodiment. These strain gauges (7a) (7a) (7b) (7b) are electrically connected to each other to form a bridge circuit (8).
[0165] 本第 4実施形態の生体情報計測用シーツの他の構成は、上記第 1実施形態と同じ である。  [0165] Other configurations of the biological information measuring sheet of the fourth embodiment are the same as those of the first embodiment.
[0166] 而して、本第 4実施形態の生体情報計測用シーツ(1)は次の利点がある。  [0166] Thus, the biological information measuring sheet (1) of the fourth embodiment has the following advantages.
[0167] 起歪板(5)の周縁部(5d)に、該周縁部(5d)を覆うエッジカバー(15)が装着され ているので、起歪板(5)の周縁部 (5d)に被験者 (H)の身体が当たることによる被験 者 (h)の痛みを軽減できる。また、シーツ本体(2)の内部に弾性シート(10)が配置さ れて 、る場合には、起歪板(5)の周縁部 (5d)で弾性シート(10)が切断される不具 合を防止できる。 [0167] Since the edge cover (15) covering the peripheral edge (5d) is attached to the peripheral edge (5d) of the strain generating plate (5), the peripheral edge (5d) of the strain generating plate (5) is attached. The pain of the subject (h) due to the contact of the subject (H) can be reduced. Further, in the case where the elastic sheet (10) is disposed inside the sheet body (2), the elastic sheet (10) is cut at the peripheral edge (5d) of the strain generating plate (5). Can be prevented.
[0168] さらに、エッジカバー(15)は断面円形状に形成されるとともに、エッジカバー(15) の周面部の一部に嵌合用溝部(15a)が起歪板(5)の周縁部 (5d)に沿って延設され 、この溝部(15a)内に起歪板(5)の周縁部 (5d)が嵌合された状態でエッジカバー(1 5)が起歪板(5)の周縁部 (5d)に装着されて!、る。したがって、起歪板(5)の周縁部 ( 5d)にエッジカバー(15)を強固に装着することができる。さらに、起歪板(5)の周縁 部(5d)に被験者 (H)の身体が当たることによる被験者 (H)の痛みを確実に軽減でき る。  [0168] Furthermore, the edge cover (15) is formed in a circular cross section, and a fitting groove (15a) is formed on a part of the peripheral surface of the edge cover (15). ) And the edge cover (15) is in the periphery of the strain plate (5) with the periphery (5d) of the strain plate (5) fitted in the groove (15a). Installed in (5d)! Therefore, the edge cover (15) can be firmly attached to the peripheral edge (5d) of the strain generating plate (5). Furthermore, the pain of the subject (H) due to the body of the subject (H) hitting the peripheral edge (5d) of the strain plate (5) can be reliably reduced.
[0169] さらに、エッジカバー(15)が榭脂製なので、エッジカバー(15)を安価に製作できる 。さらに、榭脂製のエッジカバー(15)は一般に適度な弾性を有しているので、起歪 板(5)の周縁部 (5d)にエッジカバー(15)を装着することに伴う歪み検出精度の低 下についても防止できる。  [0169] Furthermore, since the edge cover (15) is made of resin, the edge cover (15) can be manufactured at low cost. In addition, since the edge cover (15) made of resin generally has moderate elasticity, the strain detection accuracy associated with mounting the edge cover (15) on the peripheral edge (5d) of the strain generating plate (5) It can also prevent the decline of

The second elastic layer (17) has a shape corresponding to the planar shape of the strain generating plate (5), that is, a rectangular shape in plan view, and is also formed with a sheet-like urethane foam material. The second elastic layer (17) is disposed in contact with the lower surface of the strain generating plate (5), and more specifically, the second elastic layer (17) covers the entire surface of the lower surface of the strain generating plate (5). Affixed with an adhesive and arranged in a laminated state on the strain-generating plate (5). In the present invention, the second elastic layer (17) does not necessarily have to be attached to the lower surface of the strain generating plate (5). For example, the second elastic layer (17) is a strain generating plate. It can be placed on the bottom surface of (5) in a non-stick state.
[0175] 第 2弾性層(17)は、 JIS K 6401による硬さが 150〜300N (特に望ましくは 200 〜250N)であり、且つ厚さが 3〜15mm (特に望ましくは 8〜12mm)の範囲内のウレ タンフォーム材カも形成されていることが望ましい。こうすることにより、起歪板(5)の 下方向への橈曲による該起歪板(5)の剛性層( 18)への当接 ( 、わゆる「底付き」 )を 防止することができる。これにより、起歪板 (5)が更に確実に橈曲し得て、該起歪板( 5)に歪みを更に確実に生じさせることができる。 [0175] The second elastic layer (17) has a hardness according to JIS K 6401 of 150 to 300N (particularly desirably 200 to 250N) and a thickness of 3 to 15mm (particularly desirably 8 to 12mm). Ure inside It is desirable that a tan foam material is also formed. By doing so, it is possible to prevent the strain plate (5) from contacting the rigid layer (18) due to the downward bending of the strain plate (5) (so-called “bottom”). it can. As a result, the strain generating plate (5) can bend more reliably, and the strain generating plate (5) can be more surely strained.
[0176] 剛性層(18)は、寝床面(52) (図 1参照)の硬さが起歪板(5)の歪み量に与える影 響を緩和するため更には解消するためのものであり、剛性を有している。この剛性層 (18)は、起歪板 (5)の平面形状に対応した形状、即ち平面視長方形状であって、金 属板から形成されており、詳述するとアルミニウム板力 形成されており、板状の押出 材ゃ圧延材等からなる。剛性層(18)がアルミニウム板カゝら形成されることにより、シー ッ(1)の軽量ィ匕を図ることができる。そして、この剛性層 (18)は、第 2弾性層(17)の 下面に当接して配置されたものであり、詳述すると、第 2弾性層(17)の下面にその全 面を覆う状態に接着剤によって貼着されて該第 2弾性層 (17)に対して積層状態に 配置されている。なお本発明では、剛性層(18)は、第 2弾性層(17)の下面に必ずし も貼着されていることを要せず、例えば、剛性層(18)は第 2弾性層(17)の下面に非 貼着状態に配置されて ヽても良 ヽ。  [0176] The rigid layer (18) is provided to further eliminate the influence of the hardness of the bed surface (52) (see Fig. 1) on the amount of strain of the strain plate (5). , Has rigidity. The rigid layer (18) has a shape corresponding to the planar shape of the strain generating plate (5), that is, a rectangular shape in plan view, and is formed of a metal plate, and more specifically, an aluminum plate force is formed. It consists of a plate-like extruded material, a rolled material, and the like. By forming the rigid layer (18) from an aluminum plate cover, the sheet (1) can be made lighter. The rigid layer (18) is disposed in contact with the lower surface of the second elastic layer (17). More specifically, the rigid layer (18) covers the entire surface of the lower surface of the second elastic layer (17). It is adhered to the second elastic layer (17) by being stuck to the second elastic layer (17). In the present invention, the rigid layer (18) does not necessarily have to be attached to the lower surface of the second elastic layer (17). For example, the rigid layer (18) may be the second elastic layer (17 ) It can be placed in the non-sticking state on the bottom surface of).
[0177] ただし本発明では、剛性層 (18)の構成材料はアルミニウムであることに限定される ものではなぐその他に、例えば、鉄、鋼、ステンレス鋼、マグネシウム合金、銅であつ ても良 、し、繊維強化プラスチック等のプラスチックであっても良 、。  [0177] However, in the present invention, the constituent material of the rigid layer (18) is not limited to aluminum. For example, iron, steel, stainless steel, magnesium alloy, and copper may be used. However, plastic such as fiber reinforced plastic may be used.
[0178] 特に、本発明では、剛性層 (18)の構成材料と起歪板(5)の構成材料はともにアル ミニゥムであることが望ましぐこうすることにより、シーツ(1)の更なる軽量ィ匕を図ること ができる。ただし本発明では、剛性層(18)の構成材料と起歪板 (5)の構成材料とは 必ずしも同じであることを要しない。  [0178] In particular, in the present invention, it is desirable that both the constituent material of the rigid layer (18) and the constituent material of the strain generating plate (5) are aluminum, thereby further increasing the size of the sheet (1). Lightweight can be achieved. However, in the present invention, the constituent material of the rigid layer (18) and the constituent material of the strain generating plate (5) are not necessarily the same.
[0179] 剛性層(18)の曲げこわさは、起歪板(5)の曲げこわさに対して 2倍以上に設定され ていることが望ましい。こうすることにより、寝床面(52)の硬さに依らないで起歪板(5 )の歪みを更に確実に検出することができ、もって生体情報を更に正確に計測するこ とができる。なお、剛性層(18)の曲げこわさは大きければ大きいほど良ぐその上限 は本来、限定されるものではないが、一般に、曲げこわさが大きくなると剛性層(18) の重量や厚さが増大し、これに伴いシーツ(1)の重量や厚さが増大するという問題が 生じる。この問題を回避するため、剛性層(18)の曲げこわさは、通常、起歪板(5)の 曲げこわさの 5倍以下に設定されるのが望ましい。 [0179] The bending stiffness of the rigid layer (18) is preferably set to be at least twice that of the strain-generating plate (5). By doing so, it is possible to detect the distortion of the strain generating plate (5) more reliably without depending on the hardness of the bed surface (52), and thus it is possible to measure biological information more accurately. The higher the bending stiffness of the rigid layer (18), the better the upper limit is not originally limited, but in general, as the bending stiffness increases, the weight and thickness of the rigid layer (18) increase. As a result, the weight and thickness of the sheet (1) increase. Arise. In order to avoid this problem, it is desirable that the bending stiffness of the rigid layer (18) is usually set to 5 times or less the bending stiffness of the strain generating plate (5).
[0180] 本第 5実施形態の生体情報計測用シーツの他の構成は、上記第 1実施形態と同じ である。 [0180] Other configurations of the biological information measurement sheet of the fifth embodiment are the same as those of the first embodiment.
[0181] 而して、本第 5実施形態の生体情報計測用シーツ(1)は次の利点がある。  [0181] Therefore, the biological information measuring sheet (1) of the fifth embodiment has the following advantages.
[0182] 起歪板 (5)の上面に第 1弾性層(16)が配置されていることから、第 1弾性層(16) によって被験者 (H)に対して柔ら力感を与えることがきる。  [0182] Since the first elastic layer (16) is arranged on the upper surface of the strain generating plate (5), the first elastic layer (16) can give a soft feeling to the subject (H). .
[0183] さらに、起歪板 (5)の下面に第 2弾性層(17)が配置されているから、起歪板 (5)が 確実に橈曲し得て、該起歪板(5)に歪みを確実に生じさせることができる。  [0183] Furthermore, since the second elastic layer (17) is disposed on the lower surface of the strain generating plate (5), the strain generating plate (5) can bend reliably, and the strain generating plate (5) It is possible to reliably cause distortion.
[0184] さらに、第 2弾性層(17)の下面に剛性層(18)が配置されているので、寝床面(52) の硬さが起歪板(5)の歪み量に与える影響を緩和することができる。これにより、寝床 面(52)の硬さに依らな 、で起歪板(5)の歪みを確実に検出することができ、もって生 体情報を正確に計測することができる。したがって、このシーツ(1)を、ベッド(30)の マットレス(31)の上面(31a)などの柔らか 、面の上に載置して計測を行う場合に、生 体情報を正確に計測することができるし、更に、このシーツ(1)を、例えば床板面や 畳面などの硬!、面の上に載置して計測を行う場合であっても、生体情報を正確に計 測することができる。さらに、寝床面(52)が平坦面である場合はもとより、寝床面(52 )が不陸面である場合であっても、生体情報を正確に計測することができる。  [0184] Further, since the rigid layer (18) is arranged on the lower surface of the second elastic layer (17), the influence of the hardness of the bed surface (52) on the amount of strain of the strain plate (5) is mitigated. can do. Thus, the strain of the strain generating plate (5) can be reliably detected without depending on the hardness of the bed surface (52), and thus the biological information can be accurately measured. Therefore, when this sheet (1) is placed on a soft surface such as the upper surface (31a) of the mattress (31) of the bed (30) and measurement is performed, biological information must be accurately measured. In addition, even when this sheet (1) is placed on a hard surface such as a floor board surface or a tatami surface, and the measurement is performed, the biological information can be accurately measured. Can do. Furthermore, the biological information can be accurately measured not only when the bed surface (52) is a flat surface but also when the bed surface (52) is a non-land surface.

[0186] さらに、第 2弾性層(17)は、 JIS K 6401による硬さ 150〜300N、及び厚さ 3〜1 5mmのウレタンフォーム材から形成されているので、起歪板(5)の下方向への撓曲 による該起歪板(5)の剛性層(18)への当接を防止することができる。これにより、起 歪板(5)が更に確実に橈曲し得て、該起歪板(5)に歪みを更に確実に生じさせること ができる。  [0186] Furthermore, since the second elastic layer (17) is formed of a urethane foam material having a hardness of 150 to 300 N and a thickness of 3 to 15 mm according to JIS K 6401, it is under the strain plate (5). It is possible to prevent the strain plate (5) from contacting the rigid layer (18) due to bending in the direction. Thereby, the strain plate (5) can bend more reliably, and the strain can be more reliably generated in the strain plate (5).
[0187] さらに、剛性層(18)は、曲げこわさが起歪板(5)の曲げこわさに対して 2倍以上に 設定されて 、るので、寝床面(52)の硬さに依らな 、で起歪板(5)の歪みを更に確実 に検出することができ、もって生体情報を更に正確に計測することができる。 [0187] Further, since the stiffness of the rigid layer (18) is set to more than twice that of the strain-generating plate (5), it does not depend on the hardness of the bed surface (52). To further ensure the strain of the strain plate (5) Therefore, the biological information can be measured more accurately.
