Description

Translated fromJapanese

本発明は、携帯型生体情報測定装置に関する。  The present invention relates to a portable biological information measuring device.

従来、手首に装着されて、生体情報としての脈拍を測定する腕時計型の脈拍測定装置が知られている(例えば、特許文献1参照)。
この特許文献1に記載の脈拍測定装置は、凸状に形成された透光部材と、それぞれ当該透光部材内に設けられた発光素子及び受光素子とを有する脈拍検出部を備える。この他、当該脈拍測定装置は、脈拍検出部の突出量を変化させる突出量変更機構と、脈拍検出部の突出量を増減させるモーターと、当該モーターをサーボ制御する凸量制御部と、脈拍検出部の突出量の増減量を検出するエンコーダー等の回転量検出部と、を備える。
2. Description of the Related Art Conventionally, a wristwatch-type pulse measuring device that is worn on a wrist and measures a pulse as biological information is known (for example, see Patent Document 1).
The pulse measuring device described inPatent Document 1 includes a pulse detecting unit having a light-transmitting member formed in a convex shape, and a light-emitting element and a light-receiving element respectively provided in the light-transmitting member. In addition, the pulse measuring device includes a protrusion amount changing mechanism that changes the protrusion amount of the pulse detection unit, a motor that increases or decreases the protrusion amount of the pulse detection unit, a convex amount control unit that servo-controls the motor, and pulse detection. A rotation amount detection unit such as an encoder that detects an increase / decrease amount of the protrusion amount of the unit.

ここで、細動脈の血圧より強い力で、脈拍検出部が細動脈や細静脈の組織を押圧してしまうと、脈動による細動脈の容積変化があまり生じなくなり、脈動を表す信号強度が低下してしまう。
一方、安静時等の体動が小さいときは、脈拍検出部の突出量が小さい場合でも、脈拍検出が可能となるが、運動時等の体動が大きいときは、体動に起因するノイズの量が増えて、脈拍検出部の突出量が最適な状態にないと脈拍検出が困難な状態となる。
これに対し、上記脈拍測定装置では、体動等に基づいて脈拍検出部の突出量を調整することにより、適切な脈拍の検出を試みている。
Here, if the pulse detector presses the arteriole or venule tissue with a force stronger than the blood pressure of the arteriole, the arteriole volume change due to pulsation does not occur so much, and the signal intensity representing pulsation decreases. End up.
On the other hand, when body movements such as at rest are small, pulse detection is possible even when the amount of protrusion of the pulse detection unit is small, but when body movements such as during exercise are large, noise caused by body movements can be detected. If the amount increases and the amount of protrusion of the pulse detector is not optimal, pulse detection becomes difficult.
On the other hand, in the said pulse measuring device, the detection of a suitable pulse is tried by adjusting the protrusion amount of a pulse detection part based on a body motion etc.

ところで、上記特許文献1に記載の脈拍測定装置のように、発光素子及び受光素子を有する脈拍検出部を備えた測定装置では、脈拍の測定に際して、被検出部位の皮膚に、発光素子からの光が適切に照射され、当該皮膚を介した光が受光素子に適切に入射されることが重要である。
しかしながら、当該脈拍検出部は、凸状に形成された透光部材内に発光素子及び受光素子が配置された構成を有することから、脈拍検出部において被検出部位に光を出射し、かつ、被検出部位を介した光が入射される部分(換言すると、被検出部位に接触する部分)が大きくなりやすい。このため、被検出部位が、凹凸がある部位であったり、毛深い部分であったりする場合には、当該被検出部位に光を照射し、かつ、被検出部位を介した光を受光することが難しくなり、脈拍を適切に測定しづらいという問題がある。また、脈拍測定の際に、発光素子や受光素子は被検出部位にできるだけ近接させることが好ましいが、そのためにこのような光電センサーを用いた測定装置では、各素子の配置における設計自由度が低いという問題がある。
By the way, in the measuring apparatus including the pulse detecting unit having the light emitting element and the light receiving element as in the pulse measuring apparatus described inPatent Document 1, the light from the light emitting element is applied to the skin of the detection site when measuring the pulse. Is appropriately irradiated, and it is important that light through the skin is appropriately incident on the light receiving element.
However, since the pulse detection unit has a configuration in which the light emitting element and the light receiving element are arranged in a light-transmitting member formed in a convex shape, the pulse detection unit emits light to the detection site, and A portion where light is incident through the detection site (in other words, a portion that contacts the detection site) tends to be large. For this reason, in the case where the detected part is an uneven part or a hairy part, it is possible to irradiate the detected part with light and receive light through the detected part. There is a problem that it becomes difficult and it is difficult to measure the pulse properly. In addition, it is preferable that the light emitting element and the light receiving element be as close as possible to the detection site when measuring the pulse. For this reason, in a measuring apparatus using such a photoelectric sensor, the degree of freedom in designing the arrangement of each element is low. There is a problem.

本発明は、上記課題の少なくとも一部を解決することを目的としたものであり、検出光を適切に検出可能な携帯型生体情報測定装置を提供することを目的の1つとする。  An object of the present invention is to solve at least a part of the above-described problems, and an object of the present invention is to provide a portable biological information measuring device capable of appropriately detecting detection light.

本発明の一態様に係る携帯型生体情報測定装置は、被検出部位に照射される検出光を出射する発光部と、前記被検出部位を介した前記検出光を受光する受光部と、前記発光部及び前記受光部を収容する収容体と、前記収容体と接続され、前記収容体を前記被検出部位に装着させる装着部と、前記発光部からの前記検出光が入射される発光第1端部、及び、前記発光第1端部から入射された前記検出光を出射する発光第2端部を有する発光側導光部材と、前記被検出部位からの前記検出光が入射される受光第1端部、及び、前記受光第1端部から入射された前記検出光を前記受光部に出射する受光第2端部を有する受光側導光部材と、を備え、前記発光側導光部材と前記受光側導光部材とは、別体であることを特徴とする。  A portable biological information measuring device according to an aspect of the present invention includes a light emitting unit that emits detection light irradiated to a detected site, a light receiving unit that receives the detection light via the detected site, and the light emission A housing that houses the housing and the light receiving portion, a mounting portion that is connected to the housing and attaches the housing to the detection site, and a light emitting first end on which the detection light from the light emitting portion is incident And a light emitting side light guide member having a light emitting second end that emits the detection light incident from the light emitting first end, and a light receiving first in which the detection light from the detected portion is incident A light receiving side light guide member having a light receiving second end portion that emits the detection light incident from the light receiving first end portion to the light receiving portion, and the light emitting side light guide member and The light receiving side light guide member is a separate body.

なお、被検出部位は、装着部により携帯型生体情報測定装置を装着可能な身体の一部とすることができ、例えば、手首等の四肢の一部を例示できる。また、発光第2端部から出射される検出光の進行方向と、受光第1端部に入射される検出光の進行方向とは、互いに反対方向を向いていてもよく、同じ方向を向いていてもよい。すなわち、受光第1端部に入射される検出光は、発光第2端部から出射されて被検出部位にて反射された検出光でもよく、当該被検出部位を透過した検出光でもよい。  The detected part can be a part of the body to which the portable biological information measuring device can be attached by the attachment part, and for example, a part of the extremity such as a wrist can be exemplified. Further, the traveling direction of the detection light emitted from the light emitting second end portion and the traveling direction of the detection light incident on the light receiving first end portion may be opposite to each other, and are directed to the same direction. May be. That is, the detection light incident on the first light receiving end may be detection light that is emitted from the second light emission end and reflected at the detection site, or detection light that is transmitted through the detection site.

上記一態様によれば、発光側導光部材は、発光部から出射されて発光第1端部に入射された検出光を導光し、発光第2端部にて被検出部位に照射し、受光側導光部材は、受光第1端部に入射される検出光(被検出部位を介した検出光)を導光して受光第2端部から受光部に出射する。これによれば、これら導光部材が無い上記特許文献1に記載の脈拍検出部に比べて、携帯型生体情報測定装置において、被検出部位に検出光を照射する照射部となる発光第2端部、及び、被検出部位を介した検出光が入射される入射部となる受光第1端部を小さくすることができる。
このため、被検出部位に凹凸や体毛がある場合でも、これらを避けて上記発光第2端部及び受光第1端部を被検出部位に接触させやすくすることができるので、検出光が適切に照射され、かつ、検出光が適切に入射される位置に、これら発光第2端部及び受光第1端部を配置しやすくすることができる。従って、発光部から出射された検出光を被検出部位に確実に照射でき、また、当該被検出部位を介した検出光を受光部に確実に導光できるので、当該検出光を適切に検出できる。
更に、発光部から出射された検出光を被検出部位に導く発光側導光部材、及び、被検出部位から出射された検出光を受光部に導く受光側導光部材を有することにより、発光部及び受光部を、互いに近接配置する必要がない。このため、これら発光部及び受光部の配置自由度(設計自由度)を向上させることができる。
According to the above aspect, the light-emitting side light guide member guides the detection light emitted from the light-emitting unit and incident on the first light-emitting end, and irradiates the detected site at the second light-emitting end. The light-receiving side light guide member guides detection light (detection light via the detected portion) incident on the light receiving first end portion and emits the light from the light receiving second end portion to the light receiving portion. According to this, compared with the pulse detection part of the saidpatent document 1 which does not have these light guide members, in a portable biological information measuring device, the light emission 2nd end used as the irradiation part which irradiates detection light to a to-be-detected site | part And the light receiving first end portion serving as an incident portion into which detection light is incident via the detection site can be reduced.
For this reason, even if there is unevenness or body hair in the detected part, it is possible to avoid these and make the second light emitting end and the first light receiving end easily contact the detected part. It is possible to easily arrange the light emitting second end portion and the light receiving first end portion at a position where the detection light is appropriately incident. Accordingly, the detection light emitted from the light emitting unit can be reliably radiated to the detection site, and the detection light via the detection site can be reliably guided to the light receiving unit, so that the detection light can be detected appropriately. .
Further, the light emitting unit includes a light emitting side light guide member that guides the detection light emitted from the light emitting unit to the detection site, and a light receiving side light guide member that guides the detection light emitted from the detection site to the light receiving unit. And it is not necessary to arrange the light receiving parts close to each other. For this reason, the arrangement | positioning freedom degree (design freedom degree) of these light emission parts and a light-receiving part can be improved.

上記一態様では、前記発光側導光部材及び前記受光側導光部材は可撓性を有することが好ましい。
このような構成によれば、発光第2端部及び受光第1端部が被検出部位に押圧された場合でも、発光側導光部材及び受光側導光部材が撓むことにより、これら発光第2端部及び受光第1端部が被検出部位に接触した状態を維持できる。従って、検出光を安定して検出できる。
In the said one aspect | mode, it is preferable that the said light emission side light guide member and the said light reception side light guide member have flexibility.
According to such a configuration, even when the light emitting second end portion and the light receiving first end portion are pressed against the detection site, the light emitting side light guide member and the light receiving side light guide member are bent, so that The state where the two end portions and the first light receiving end portion are in contact with the detected portion can be maintained. Therefore, the detection light can be detected stably.

上記一態様では、前記発光第1端部は、前記発光部と向かい合うように配置され、前記受光第2端部は、前記受光部と向かい合うように配置されていることが好ましい。
このような構成によれば、発光部から出射された光を発光第1端部に入射させやすくすることができ、当該光を確実に発光側導光部材により発光第2端部から照射できる。また、受光第1端部に入射されて受光側導光部材によって導かれた検出光を受光第2端部から出射して、当該検出光を受光部に入射させやすくすることができる。従って、被検出部位を介した検出光の検出精度を向上させることができる。
In the above aspect, it is preferable that the light emitting first end portion is disposed so as to face the light emitting portion, and the light receiving second end portion is disposed so as to face the light receiving portion.
According to such a configuration, the light emitted from the light emitting portion can be easily incident on the first light emitting end portion, and the light can be reliably irradiated from the second light emitting end portion by the light emitting side light guide member. In addition, the detection light that is incident on the first light receiving end and guided by the light receiving side light guide member is emitted from the second light receiving end so that the detection light can easily enter the light receiving unit. Therefore, it is possible to improve the detection accuracy of the detection light via the detection site.

上記一態様では、前記発光第1端部は、前記発光部に接続され、前記受光第2端部は、前記受光部に接続されていることが好ましい。
このような構成によれば、発光部から出射された検出光を確実に発光側導光部材に入射させることができる他、受光側導光部材によって導かれた検出光を確実に受光部に入射させることができる。従って、被検出部位を介した検出光の検出精度を一層向上させることができる。
In the one aspect, it is preferable that the light emitting first end is connected to the light emitting unit, and the light receiving second end is connected to the light receiving unit.
According to such a configuration, the detection light emitted from the light emitting unit can be reliably incident on the light emitting side light guide member, and the detection light guided by the light receiving side light guide member can be reliably incident on the light receiving unit. Can be made. Therefore, it is possible to further improve the detection accuracy of the detection light via the detection site.

上記一態様では、前記発光第2端部と前記受光第1端部とは、前記収容体から前記被検出部位に向かう方向に沿って、前記収容体から突出していることが好ましい。
このような構成によれば、発光第2端部及び受光第1端部を被検出部位に接触させやすくすることができる。従って、携帯型生体情報測定装置の被検出部位への装着を容易に行うことができる。
また、発光第2端部及び受光第1端部の収容体からの突出方向は、装着部によって収容体が被検出部位に装着される際の当該被検出部位に向かう方向である。このため、発光第2端部から被検出部位に検出光を適切に照射できる他、当該被検出部位を介した検出光を受光第1端部に入射させやすくすることができる。従って、当該検出光の検出精度を一層向上させることができる。
In the above aspect, it is preferable that the light emitting second end portion and the light receiving first end portion protrude from the container along a direction from the container toward the detection site.
According to such a configuration, the second light emitting end and the first light receiving end can be easily brought into contact with the detection site. Therefore, the portable biological information measuring device can be easily attached to the detection site.
In addition, the protruding direction of the light emitting second end portion and the light receiving first end portion from the housing is a direction toward the detected site when the housing is mounted on the detected site by the mounting portion. For this reason, in addition to being able to appropriately irradiate the detection site from the second light emitting end, it is possible to easily make the detection light via the detection site incident on the first light receiving end. Therefore, the detection accuracy of the detection light can be further improved.

上記一態様では、前記発光側導光部材及び前記受光側導光部材の前記収容体からの突出部分を囲み、前記発光第2端部及び前記受光第1端部を露出させる弾性部材を有することが好ましい。
このような弾性部材は、中空でも中実でもよい。
上記構成によれば、上記発光第2端部及び受光第1端部を適度な圧力で被検出部位に接触させることができる。従って、検出光の検出を安定化できる。また、弾性部材が遮光性を有する材料により構成されていれば、受光側導光部材に外光が入射されることを抑制できる。従って、外光を受光部が検出してしまうことを抑制でき、検出光の検出精度を一層向上させることができる。
In the said one aspect | mode, it has the elastic member which surrounds the protrusion part from the said accommodating body of the said light emission side light guide member and the said light reception side light guide member, and exposes the said light emission 2nd edge part and the said light reception 1st edge part. Is preferred.
Such an elastic member may be hollow or solid.
According to the said structure, the said light emission 2nd edge part and the light reception 1st edge part can be made to contact a to-be-detected site | part with moderate pressure. Therefore, detection of detection light can be stabilized. Moreover, if the elastic member is comprised with the material which has light-shielding property, it can suppress that external light injects into a light-receiving side light guide member. Therefore, it is possible to suppress detection of external light by the light receiving unit, and it is possible to further improve the detection accuracy of the detection light.

上記一態様では、前記弾性部材は、前記収容体からの前記発光側導光部材及び前記受光側導光部材の突出方向に向かうに従って外形が小さくなることが好ましい。
このような構成によれば、弾性部材は、上記突出方向に向かうに従って細くなる形状を有することから、上記発光第2端部及び受光第1端部が位置する部位をより小さくすることができる。このため、被検出部位において適した部位に、当該発光第2端部及び受光第1端部を配置しやすくすることができる。従って、検出光を適切かつ確実に検出できる。
In the said one aspect | mode, it is preferable that the external shape becomes small as the said elastic member goes to the protrusion direction of the said light emission side light guide member and the said light reception side light guide member from the said container.
According to such a structure, since an elastic member has a shape which becomes thin as it goes to the said protrusion direction, the site | part in which the said light emission 2nd edge part and light reception 1st edge part are located can be made smaller. For this reason, the said light emission 2nd edge part and light reception 1st edge part can be easily arrange | positioned in the site | part suitable in a to-be-detected site | part. Therefore, the detection light can be detected appropriately and reliably.

上記一態様では、前記発光第2端部と前記受光第1端部とを固定する固定部を有することが好ましい。
ここで、発光側導光部材において検出光を出射する発光第2端部と、受光側導光部材において検出光が入射される受光第1端部とが離れていたり、これら端部が異なる方向を向いてしまうと、発光側導光部材によって出射されて被検出部位を介した検出光を受光側導光部材に入射させづらくなるという問題が生じる。特に、上記のように、発光側導光部材と受光側導光部材とが可撓性を有する場合には、発光第2端部及び受光第1端部が被検出部位に接触する等して発光側導光部材と受光側導光部材に圧力が加わると、当該問題が生じる可能性が高くなる。
これに対し、固定部によって発光第2端部及び受光第1端部が固定されることにより、被検出部位を介した検出光を、受光第1端部を介して受光側導光部材に適切に入射させやすくすることができる。従って、検出光の検出を安定化できる。
In the said one aspect | mode, it is preferable to have a fixing | fixed part which fixes the said light emission 2nd edge part and the said light reception 1st edge part.
Here, the light emitting second end portion that emits the detection light in the light emitting side light guide member and the light receiving first end portion where the detection light is incident in the light receiving side light guide member are separated from each other, or these end portions are in different directions. , The problem arises that it becomes difficult for the detection light emitted by the light-emitting side light guide member to enter the light-receiving side light guide member. In particular, as described above, when the light-emitting side light guide member and the light-receiving side light guide member have flexibility, the light emitting second end portion and the light receiving first end portion are in contact with the detection site. When pressure is applied to the light-emitting side light guide member and the light-receiving side light guide member, there is a high possibility that the problem will occur.
On the other hand, the light emitting second end and the light receiving first end are fixed by the fixing portion, so that the detection light via the detected portion is appropriately applied to the light receiving side light guide member via the light receiving first end. It can be made easy to enter. Therefore, detection of detection light can be stabilized.

上記一態様では、前記発光第2端部と前記受光第1端部とに接続されるレンズを備えることが好ましい。
上記構成によれば、発光第2端部から出射された検出光の照射範囲を小さくできる他、被検出部位を介した検出光を集光して受光第1端部に入射させることができる。従って、検出光を効率よく照射及び集光できるので、当該検出光の検出精度を向上させることができる。
In the said one aspect | mode, it is preferable to provide the lens connected to the said light emission 2nd edge part and the said light reception 1st edge part.
According to the above configuration, it is possible to reduce the irradiation range of the detection light emitted from the light emitting second end portion, and it is possible to collect the detection light via the detected portion and enter the light receiving first end portion. Therefore, since the detection light can be efficiently irradiated and condensed, the detection accuracy of the detection light can be improved.

上記一態様では、少なくとも前記受光側導光部材を囲む遮蔽部材を備え、前記遮蔽部材は、前記受光側導光部材が挿通する孔部を有することが好ましい。
このような構成によれば、遮蔽部材によって、被検出部位を介した検出光以外の光(例えば外光)が受光側導光部材に入射されることを抑制できる。従って、検出光の検出精度を向上させることができる。
In the said one aspect | mode, it is preferable to provide the shielding member surrounding at least the said light reception side light guide member, and the said shielding member has a hole part which the said light reception side light guide member penetrates.
According to such a structure, it can suppress that lights (for example, external light) other than the detection light which passed through the to-be-detected part inject into a light reception side light guide member by a shielding member. Therefore, the detection accuracy of the detection light can be improved.

上記一態様では、前記発光部及び前記受光部が配設される基板を有し、前記基板は、前記発光部と前記受光部との間に位置する遮光部を有することが好ましい。
このような構成によれば、遮光部によって、発光部から出射された検出光が受光部に直接入射されることを抑制できる。従って、受光側導光部材を介して受光部により受光される検出光の検出精度を向上させることができる。
In the said one aspect | mode, it has a board | substrate with which the said light emission part and the said light reception part are arrange | positioned, and it is preferable that the said board | substrate has a light-shielding part located between the said light emission part and the said light reception part.
According to such a structure, it can suppress that the detection light radiate | emitted from the light emission part directly injects into a light-receiving part by the light-shielding part. Therefore, the detection accuracy of the detection light received by the light receiving unit via the light receiving side light guide member can be improved.

上記一態様では、前記受光部による前記検出光の検出結果に基づいて、生体情報を測定する処理回路を備えることが好ましい。
このような構成によれば、精度の高い生体情報を測定できる。
In the said one aspect | mode, it is preferable to provide the processing circuit which measures biological information based on the detection result of the said detection light by the said light-receiving part.
According to such a configuration, highly accurate biological information can be measured.

Further, the light shielding portion may be configured by a member different from thecircuit element 52.

[導光部材の構成]
導光部材73は、発光側導光部材に相当し、一方の端部731(発光第1端部)は、発光部71と向かい合うように配置され、他方の端部732(発光第2端部)は、背面部32に形成された孔部321を通って当該背面部32の外面32Bより外側に突出している。すなわち、端部731は、発光部71の発光面に接続され、当該端部731には、発光部71から出射された検出光が入射される。また、端部732は、装置本体2Aが装着部位MSに装着された際の被検出部位DSに向かう方向に沿って収容体3Aの背面部32から突出し、導光部材73内にて伝導されて導光された検出光を被検出部位DSに向けて出射する。このような導光部材73は、可撓性を有することが好ましく、例えば光ファイバーにより構成できる。
[Configuration of light guide member]
Thelight guide member 73 corresponds to a light emission side light guide member, and one end portion 731 (light emission first end portion) is arranged to face thelight emission portion 71 and the other end portion 732 (light emission second end portion). ) Protrudes outside theouter surface 32 </ b> B of theback surface portion 32 through thehole 321 formed in theback surface portion 32. That is, theend 731 is connected to the light emitting surface of thelight emitting unit 71, and the detection light emitted from thelight emitting unit 71 is incident on theend 731. Theend portion 732 protrudes from theback surface portion 32 of thecontainer 3A along the direction toward the detected portion DS when the apparatusmain body 2A is attached to the attachment portion MS, and is conducted in thelight guide member 73. The guided detection light is emitted toward the detected part DS. Such alight guide member 73 preferably has flexibility, and can be constituted by an optical fiber, for example.

導光部材74は、受光側導光部材に相当し、一方の端部741(受光第2端部)は、受光部72と向かい合うように配置され、他方の端部742(受光第1端部)は、背面部32に形成された孔部322を通って上記外面32Bから外側に突出している。すなわち、端部742は、端部732と同様に、装置本体2Aが装着部位MSに装着された際の被検出部位DSに向かう方向に沿って収容体3Aの背面部32から突出し、当該端部742には、被検出部位DSの皮下にて反射された検出光が入射される。また、端部741は、受光部72の受光面に接続され、導光部材74内にて伝導されて導光された検出光を受光部72に向けて出射する。これにより、上記受光部72が、上記検出信号を処理回路に出力する。この導光部材74も可撓性を有することが好ましく、例えば光ファイバーにより構成できる。  Thelight guide member 74 corresponds to a light receiving side light guide member, and one end portion 741 (light receiving second end portion) is disposed so as to face thelight receiving portion 72 and the other end portion 742 (light receiving first end portion). ) Protrudes outward from theouter surface 32 </ b> B through ahole 322 formed in theback surface portion 32. That is, theend portion 742 protrudes from theback surface portion 32 of thecontainer 3A along the direction toward the detected portion DS when the apparatusmain body 2A is attached to the attachment portion MS, similarly to theend portion 732. In 742, the detection light reflected under the detection site DS is incident. Theend portion 741 is connected to the light receiving surface of thelight receiving portion 72, and emits detection light conducted and guided in thelight guide member 74 toward thelight receiving portion 72. Thereby, thelight receiving unit 72 outputs the detection signal to the processing circuit. Thelight guide member 74 also preferably has flexibility, and can be constituted by an optical fiber, for example.

このように、導光部材73,74は、別体として構成され、それぞれ独立して、一端側の端部731,741が発光部71の発光面及び受光部72の受光面と接続され、他端側の端部732,742が収容体3A外に突出している。
なお、本実施形態では、導光部材73の端部731は、発光部71の発光面の略全てを覆うように接続され、導光部材74の端部741は、受光部72の受光面の略全てを覆うように接続されている。しかしながら、端部731は、発光部71から出射された検出光が入射されれば、発光面の略全てを覆う必要はない。端部741も、受光部72に検出光を出射できれば、受光面の略全てを覆う必要はない。
Thus, thelight guide members 73 and 74 are configured as separate bodies, and theend portions 731 and 741 on one end side are independently connected to the light emitting surface of thelight emitting unit 71 and the light receiving surface of thelight receiving unit 72, respectively.End portions 732 and 742 on the end side protrude outside thecontainer 3A.
In the present embodiment, theend portion 731 of thelight guide member 73 is connected so as to cover substantially the entire light emitting surface of thelight emitting portion 71, and theend portion 741 of thelight guide member 74 is the light receiving surface of thelight receiving portion 72. It is connected to cover almost all. However, theend portion 731 does not need to cover substantially the entire light emitting surface if the detection light emitted from thelight emitting portion 71 is incident. As long as theend portion 741 can emit detection light to thelight receiving portion 72, it is not necessary to cover substantially the entire light receiving surface.

このような導光部材73,74が孔部321,322は、背面部32において互いに近い位置に形成されている。これにより、導光部材73によって照射されて被検出部位DSの皮下にて反射された検出光を、効率よく導光部材74、ひいては、受光部72に入射させることができる。すなわち、本実施形態に係る測定装置1Aにおいて、検出光の入出射部PTは、被検出部位DSに検出光を出射する端部732、及び、被検出部位DSを介した検出光が入射される端部742のそれぞれが位置する部分である。  Thelight guide members 73 and 74 are formed so that thehole portions 321 and 322 are close to each other in theback surface portion 32. Thereby, the detection light irradiated by thelight guide member 73 and reflected under the detection site DS under the skin can be efficiently incident on thelight guide member 74 and thus thelight receiving portion 72. That is, in themeasurement apparatus 1A according to the present embodiment, the detection light incident / exit section PT is incident on theend portion 732 that emits the detection light to the detection site DS and the detection light that has passed through the detection site DS. Each of theend portions 742 is a portion.

[第1実施形態の効果]
以上説明した本実施形態に係る測定装置1Aによれば、以下の効果がある。
導光部材73は、発光部71から出射されて端部731から入射された検出光を導光して、端部732から被検出部位DSに向けて出射し、導光部材74は、当該被検出部位DSを介して端部742から入射された検出光を導光して、端部741から受光部72に出射する。これによれば、これら導光部材73,74が無い場合に比べて、端部732,742を含んで構成される上記入出射部PTを小さくすることができる。
このため、被検出部位DSに凹凸や体毛がある場合でも、これらを避けて入出射部PTを被検出部位DSに接触させやすくすることができるので、検出光が適切に照射され、かつ、検出光が適切に入射される位置に、入出射部PTを配置しやすくすることができる。これにより、発光部71から出射された検出光を被検出部位DSに確実に照射でき、かつ、当該被検出部位DSを介した検出光を受光部72に確実に導光できる。従って、当該検出光を適切に検出でき、ひいては、生体情報の測定精度を向上させることができる。
また、発光部71から出射された検出光を被検出部位DSに導く発光側導光部材73、及び、被検出部位DSから出射された検出光を受光部72に導く受光側導光部材74を有することにより、発光部71及び受光部72を、互いに近接配置する必要がない。このため、これら発光部71及び受光部72の配置自由度(設計自由度)を向上させることができる。
[Effect of the first embodiment]
The measuringapparatus 1A according to the present embodiment described above has the following effects.
Thelight guide member 73 guides the detection light emitted from thelight emitting portion 71 and incident from theend portion 731 and emits the detection light from theend portion 732 toward the detection site DS. The detection light incident from theend portion 742 through the detection part DS is guided and emitted from theend portion 741 to thelight receiving portion 72. According to this, compared with the case where theselight guide members 73 and 74 are not provided, the said incident / exit part PT comprised including theedge parts 732 and 742 can be made small.
For this reason, even if there is unevenness and body hair in the detected part DS, it is possible to easily contact the input / output part PT with the detected part DS by avoiding these, so that the detection light is appropriately irradiated and detected The entrance / exit part PT can be easily arranged at a position where light is appropriately incident. Thereby, the detection light emitted from thelight emitting unit 71 can be reliably irradiated onto the detection site DS, and the detection light via the detection site DS can be reliably guided to thelight receiving unit 72. Therefore, the detection light can be detected appropriately, and as a result, the measurement accuracy of biological information can be improved.
In addition, a light emitting sidelight guide member 73 that guides the detection light emitted from thelight emitting unit 71 to the detected part DS, and a light receiving sidelight guide member 74 that guides the detection light emitted from the detected part DS to thelight receiving part 72 By having it, it is not necessary to arrange thelight emitting part 71 and thelight receiving part 72 close to each other. For this reason, the arrangement | positioning freedom degree (design freedom degree) of theselight emission parts 71 and the light-receivingpart 72 can be improved.

導光部材73,74はそれぞれ可撓性を有する。これによれば、入出射部PTが被検出部位DSに押圧された場合でも、収容体3Aから突出した導光部材73,74が撓むことにより、入出射部PTが被検出部位DSに接触した状態を維持しやすくすることができる。従って、検出光を安定して検出できる。  Thelight guide members 73 and 74 have flexibility. According to this, even when the incident / exit part PT is pressed against the detected part DS, thelight guide members 73 and 74 protruding from thehousing 3A bend, so that the incident / exit part PT contacts the detected part DS. This makes it easy to maintain the state. Therefore, the detection light can be detected stably.

発光側導光部材である導光部材73の端部731は、発光部71と向かい合うように配置され、受光側導光部材である導光部材74の端部741は、受光部72と向かい合うように配置されている。これによれば、発光部71から出射された光を当該端部731に入射させやすくすることができ、当該光を確実に導光部材73により端部732から照射できる。また、端部742に入射されて導光部材74によって導かれた検出光を、端部741から出射して、当該検出光を受光部72に入射させやすくすることができる。従って、被検出部位DSを介した検出光の検出精度を向上させることができる。  Theend portion 731 of thelight guide member 73 that is the light-emitting side light guide member is disposed so as to face thelight emitting portion 71, and theend portion 741 of thelight guide member 74 that is the light-receiving side light guide member faces thelight receiving portion 72. Is arranged. According to this, the light emitted from thelight emitting unit 71 can be easily incident on theend portion 731, and the light can be reliably irradiated from theend portion 732 by thelight guide member 73. Further, the detection light that is incident on theend portion 742 and guided by thelight guide member 74 can be emitted from theend portion 741 so that the detection light can easily enter thelight receiving portion 72. Therefore, it is possible to improve the detection accuracy of the detection light via the detection site DS.

端部731は、発光部71に接続され、端部741は、受光部72に接続されている。これによれば、発光部71から出射された検出光を確実に導光部材73に入射させることができる他、導光部材74によって導かれた検出光を確実に受光部72に入射させることができる。従って、被検出部位DSを介した検出光の検出精度を一層向上させることができる。  Theend portion 731 is connected to thelight emitting portion 71, and theend portion 741 is connected to thelight receiving portion 72. According to this, the detection light emitted from thelight emitting unit 71 can be reliably incident on thelight guide member 73, and the detection light guided by thelight guide member 74 can be reliably incident on thelight receiving unit 72. it can. Therefore, it is possible to further improve the detection accuracy of the detection light via the detection site DS.

端部732,742は、収容体3Aから被検出部位DSに向かう方向に沿って、当該収容体3Aの背面部32から突出している。これによれば、端部732,742を被検出部位DSに接触させやすくすることができる。従って、測定装置1Aの装着部位MS(被検出部位DS)への装着を容易に行うことができる。
また、端部732,742の収容体3Aからの突出方向は、装着部としてのバンドBN1,BN2によって収容体3Aが装着部位MSに装着される際の被検出部位DSに向かう方向である。このため、端部732から被検出部位DSに検出光を適切に照射できる他、当該被検出部位DSを介した検出光を端部742に入射させやすくすることができる。従って、当該検出光の検出精度を一層向上させることができる。
Theend portions 732 and 742 protrude from theback surface portion 32 of thecontainer 3A along the direction from thecontainer 3A toward the detection site DS. According to this, theend portions 732 and 742 can be easily brought into contact with the detection site DS. Therefore, themeasurement apparatus 1A can be easily attached to the attachment part MS (detected part DS).
Further, the protruding direction of theend portions 732 and 742 from thehousing 3A is a direction toward the detected portion DS when thehousing 3A is mounted on the mounting portion MS by the bands BN1 and BN2 as mounting portions. For this reason, the detection light can be appropriately irradiated from theend 732 to the detected part DS, and the detection light via the detected part DS can be easily incident on theend 742. Therefore, the detection accuracy of the detection light can be further improved.

実装面51Aには、発光部71と受光部72との間に位置して遮光部として機能する回路素子52が実装されている。これによれば、当該回路素子52によって、発光部71から出射された検出光が受光部72に直接入射されることを抑制できる。従って、受光部72によって受光される検出光の検出精度を向上させることができる。  On the mountingsurface 51A, acircuit element 52 that is located between thelight emitting unit 71 and thelight receiving unit 72 and functions as a light shielding unit is mounted. According to this, it is possible to suppress the detection light emitted from thelight emitting unit 71 from being directly incident on thelight receiving unit 72 by thecircuit element 52. Therefore, the detection accuracy of the detection light received by thelight receiving unit 72 can be improved.

上記測定装置1Aは、受光部72による検出光の検出結果に基づいて、生体情報を測定する処理回路を含む回路素子52を備える。これによれば、上記のように受光部72によって受光される検出光の検出精度が向上されているので、精度の高い生体情報を測定できる。  Themeasurement apparatus 1 </ b> A includes acircuit element 52 including a processing circuit that measures biological information based on the detection result of the detection light by thelight receiving unit 72. According to this, since the detection accuracy of the detection light received by thelight receiving unit 72 is improved as described above, highly accurate biological information can be measured.

[Third Embodiment]
Next, a third embodiment of the present invention will be described.
The biological information measuring apparatus according to the present embodiment is different from the biologicalinformation measuring apparatus 1A in that it has the same configuration as the biologicalinformation measuring apparatus 1A and further includes an elastic member and a translucent member. In the following description, parts that are the same as or substantially the same as those already described are assigned the same reference numerals and description thereof is omitted.

図5は、本実施形態に係る生体情報測定装置1Cを示す断面図である。
本実施形態に係る生体情報測定装置1Cは、上記生体情報測定装置1Aと同様の構成及び機能に加えて、図5に示すように、収容体3Aの背面部32に設けられる弾性部材81と、当該弾性部材81内に位置する各導光部材73,74の端部732,742と接続される透光性部材82と、を備える。
FIG. 5 is a cross-sectional view showing a biological information measuring apparatus 1C according to the present embodiment.
In addition to the same configuration and function as the biologicalinformation measuring device 1A, the biological information measuring device 1C according to the present embodiment includes anelastic member 81 provided on theback surface 32 of thecontainer 3A, as shown in FIG. Atranslucent member 82 connected to theends 732 and 742 of thelight guide members 73 and 74 located in theelastic member 81.

弾性部材81は、収容体3Aの背面部32に設けられており、例えばゴムや合成樹脂等の弾性変形可能な材料により形成されている。この弾性部材81は、背面部32から離れる方向であり、収容体3Aからの導光部材73,74の突出方向でもあるD方向に向かうに従って外形が小さくなる形状に形成されている。
そして、背面部32の上記孔部321,322を挿通した導光部材73,74は、弾性部材81によって囲まれ、これらの端部732,742は、弾性部材81の先端部81Aから外側(D方向側)に突出している。
このような弾性部材81は、外光に対する遮光性を有する遮蔽部材でもあり、これにより、弾性部材81内に位置する導光部材73,74に外光が入射されることが抑制される。このような弾性部材81は、本実施形態では中実に形成されているが、中空に形成されていてもよい。
Theelastic member 81 is provided on theback surface portion 32 of thecontainer 3A, and is formed of an elastically deformable material such as rubber or synthetic resin. Theelastic member 81 is formed in such a shape that the outer shape becomes smaller in the direction away from theback surface portion 32 and toward the D direction, which is also the protruding direction of thelight guide members 73 and 74 from thehousing 3A.
Thelight guide members 73 and 74 inserted through thehole portions 321 and 322 of theback surface portion 32 are surrounded by theelastic member 81, and theseend portions 732 and 742 are outside from thefront end portion 81 </ b> A of the elastic member 81 (D (Direction side).
Such anelastic member 81 is also a shielding member having a light shielding property against external light, and thereby, it is suppressed that external light is incident on thelight guide members 73 and 74 located in theelastic member 81. Such anelastic member 81 is formed solid in the present embodiment, but may be formed hollow.

透光性部材82は、少なくとも検出光の波長が含まれる波長範囲の光を透過させる部材である。この透光性部材82は、弾性部材81の先端部81Aを覆うように設けられ、当該先端部81Aから突出した導光部材73,74の各端部731,741が接続される。
このような透光性部材82は、端部731から出射された検出光を被検出部位DSに集束させ、かつ、当該被検出部位DSを介した検出光を集光して導光部材74に入射させるレンズ(ピックアップレンズ)として機能する。
この他、透光性部材82は、各端部732,742が互いに比較的近い位置に配置されるように、これら端部732,742を固定する固定部としても機能する。このため、透光性部材82は、導光部材73,74より硬い材料により構成することが好ましい。
そして、透光性部材82から被検出部位DSに向けて端部732から出射された検出光が出射され、被検出部位DSを介した検出光は当該透光性部材82を介して端部742に入射されるので、本実施形態では、測定装置1Cにおける入出射部PTは、透光性部材82の配置部分となる。
なお、透光性部材82は、D方向に向かうに従って断面積が小さくなり、先端部分が所定の曲率半径を有する曲面形状に形成されている。このため、弾性部材81及び透光性部材82は、全体が山型状(ドーム状)に形成されている。
Thetranslucent member 82 is a member that transmits light in a wavelength range including at least the wavelength of detection light. Thetranslucent member 82 is provided so as to cover thedistal end portion 81A of theelastic member 81, and theend portions 731 and 741 of thelight guide members 73 and 74 protruding from thedistal end portion 81A are connected.
Such atranslucent member 82 focuses the detection light emitted from theend portion 731 onto the detected part DS and condenses the detection light via the detected part DS to thelight guide member 74. Functions as an incident lens (pickup lens).
In addition, thetranslucent member 82 also functions as a fixing portion that fixes theend portions 732 and 742 such that theend portions 732 and 742 are disposed at positions relatively close to each other. For this reason, thetranslucent member 82 is preferably made of a material harder than thelight guide members 73 and 74.
Then, the detection light emitted from theend portion 732 is emitted from thetranslucent member 82 toward the detection site DS, and the detection light via the detection site DS passes through thetranslucent member 82 and theend portion 742. In this embodiment, the incident / exit part PT in the measuringapparatus 1 </ b> C serves as an arrangement part of thetranslucent member 82.
Note that thetranslucent member 82 has a cross-sectional area that decreases in the direction D, and the tip portion is formed in a curved shape having a predetermined radius of curvature. For this reason, the wholeelastic member 81 andtranslucent member 82 are formed in a mountain shape (dome shape).

このような測定装置1Cが上記装着部位MSに装着される際には、透光性部材82が当該装着部位MS(被検出部位DS)に接触する。この状態で、収容体3Aに設けられたバンドBN1,BN2を締めて、当該収容体3Aが装着部位MSに近接する方向に移動すると、弾性部材81が弾性変形して、透光性部材82が被検出部位DSに密着する。すなわち、弾性部材81は、入出射部PTである透光性部材82を被検出部位DSに向けて付勢する付勢部材として機能する。
この際、導光部材73,74は上記のように可撓性を有するので、弾性部材81の弾性変形に応じて、これら導光部材73,74は撓む。これにより、発光部71から出射された検出光を導光部材73によって端部732側に安定して導光できる。そして、端部732から出射された検出光は、透光性部材82を介して被検出部位DSに照射される。この被検出部位DSを介した検出光は、透光性部材82によって集光され、端部742を介して導光部材74に入射される。そして、当該検出光は、導光部材74により受光部72に導光され、当該受光部72によって、導光された検出光の強度に応じた信号である脈波信号が出力される。
When such a measuring apparatus 1C is attached to the attachment part MS, thetranslucent member 82 comes into contact with the attachment part MS (detection part DS). In this state, when the bands BN1 and BN2 provided on thecontainer 3A are tightened and thecontainer 3A moves in a direction close to the mounting part MS, theelastic member 81 is elastically deformed, and thetranslucent member 82 is formed. Close contact with the detection site DS. That is, theelastic member 81 functions as an urging member that urges thetranslucent member 82 that is the incident / exit portion PT toward the detection site DS.
At this time, since thelight guide members 73 and 74 have flexibility as described above, thelight guide members 73 and 74 bend according to the elastic deformation of theelastic member 81. Thereby, the detection light emitted from thelight emitting portion 71 can be stably guided to theend portion 732 side by thelight guide member 73. Then, the detection light emitted from theend portion 732 is applied to the detection site DS via thetranslucent member 82. The detection light that has passed through the detected part DS is collected by thetranslucent member 82 and enters thelight guide member 74 through theend 742. The detection light is guided to thelight receiving unit 72 by thelight guide member 74, and a pulse wave signal that is a signal corresponding to the intensity of the guided detection light is output by thelight receiving unit 72.

なお、本実施形態では、上記回路素子52や、生体情報検出部7を構成する発光部71及び受光部72は、収容体3A内に配置される上記基板51において背面部32の内面32Aに対向する面に実装されている。そして、本実施形態においても、発光部71及び受光部72は、実装面51Aにおいて比較的近い位置に配置されており、これら発光部71及び受光部72の間には、上記遮光部51A1が突設されている。なお、遮光部51A1は、回路素子52により構成されてもよく、発光部71及び受光部72は、互いに離れて配置されていてもよい。  In the present embodiment, thecircuit element 52 and thelight emitting unit 71 and thelight receiving unit 72 constituting the biologicalinformation detecting unit 7 are opposed to theinner surface 32A of theback surface 32 in thesubstrate 51 arranged in thehousing 3A. It is mounted on the surface. Also in this embodiment, thelight emitting unit 71 and thelight receiving unit 72 are disposed at relatively close positions on the mountingsurface 51A, and the light shielding unit 51A1 protrudes between thelight emitting unit 71 and thelight receiving unit 72. It is installed. In addition, light-shielding part 51A1 may be comprised by thecircuit element 52, and thelight emission part 71 and the light-receivingpart 72 may be arrange | positioned mutually apart.

[第3実施形態の効果]
以上説明した本実施形態に係る測定装置1Cによれば、上記測定装置1A,1Bと同様の効果の他、以下の効果を奏することができる。
測定装置1Cは、導光部材73,74の収容体3Aからの突出部分を囲む弾性部材81を有し、当該導光部材73,74の各端部732,742は、弾性部材81の先端部81Aから外側に露出している。そして、当該先端部81Aには、各端部732,742と接続される透光性部材82が設けられている。これによれば、導光部材73によって導光された検出光が出射され、かつ、導光部材74に検出光が入射される入出射部PTである透光性部材82を、被検出部位DSに適度な圧力で接触させることができる。従って、検出光の検出を安定化できる。
[Effect of the third embodiment]
According to the measuring apparatus 1C according to the present embodiment described above, the following effects can be obtained in addition to the same effects as the measuringapparatuses 1A and 1B.
The measuringapparatus 1 </ b> C includes anelastic member 81 that surrounds the protruding portion of thelight guide members 73 and 74 from the housing 3 </ b> A, and theend portions 732 and 742 of thelight guide members 73 and 74 are the tip portions of theelastic member 81. It is exposed to the outside from 81A. Thedistal end portion 81A is provided with atranslucent member 82 connected to theend portions 732 and 742. According to this, the detection light guided by thelight guide member 73 is emitted, and thetranslucent member 82 that is the incident / exit part PT where the detection light is incident on thelight guide member 74 is detected by the detected portion DS. Can be contacted at an appropriate pressure. Therefore, detection of detection light can be stabilized.

弾性部材81は、収容体3Aからの導光部材73,74の突出方向であるD方向に向かうに従って外形が小さくなる。そして、弾性部材81は、透光性部材82と組み合わされて山型状をなす。これによれば、入出射部PTである透光性部材82をより小さくすることができる。従って、被検出部位DSにおいて検出光の検出に適した部位に、入出射部PT、ひいては、測定装置1Cを配置させやすくすることができる。  The outer shape of theelastic member 81 decreases in the direction D, which is the direction in which thelight guide members 73 and 74 protrude from thehousing 3A. Theelastic member 81 is combined with thetranslucent member 82 to form a mountain shape. According to this, thetranslucent member 82 which is the incident / exit part PT can be made smaller. Therefore, it is possible to easily place the incident / exit section PT and, consequently, the measuring apparatus 1C in a portion suitable for detection of detection light in the detected portion DS.

透光性部材82は、導光部材73,74の端部732,742を固定する固定部としても機能する。これによれば、被検出部位DSに検出光が適切に照射され、かつ、当該被検出部位DSを介した検出光が導光部材74に適切に入射されるように、各端部732,742を固定できる。従って、検出光の検出を安定化できる。  Thetranslucent member 82 also functions as a fixing portion that fixes theend portions 732 and 742 of thelight guide members 73 and 74. According to this, each of theend portions 732 and 742 is such that the detection light is appropriately irradiated to the detection site DS and the detection light via the detection site DS is appropriately incident on thelight guide member 74. Can be fixed. Therefore, detection of detection light can be stabilized.

透光性部材82は、導光部材73,74の端部732,742と接続されるレンズとしても機能する。これによれば、端部732から出射される検出光の被検出部位DSへの照射範囲を小さくできる他、当該被検出部位DSを介した検出光を集光して端部742に入射させることができる。従って、検出光を効率よく照射及び集光できるので、当該検出光の検出精度を向上させることができる。  Thetranslucent member 82 also functions as a lens connected to theend portions 732 and 742 of thelight guide members 73 and 74. According to this, the irradiation range of the detection light emitted from theend portion 732 to the detected portion DS can be reduced, and the detection light via the detected portion DS is condensed and incident on theend portion 742. Can do. Therefore, since the detection light can be efficiently irradiated and condensed, the detection accuracy of the detection light can be improved.
