Description

本発明は、例えば、耳に装着して血流を検出する生体情報検出装置に関する。 The present invention relates to, for example, a biological information detection device worn on an ear to detect blood flow.

例えば、特許文献１に開示された血流センサは、インナーイヤー型のヘッドフォンに適用されたものであり、ハウジングと、ハウジングに設けられたイヤーピース及びセンサ素子とを備えている。イヤーピースが外耳道に挿入されている状態では、センサ素子が耳珠に接触するとともに、センサ素子により血流が検出される。センサ素子は、ハウジング内に設けられた弾性体に支持されている。弾性体は、外耳道へのイヤーピースの挿入方向と直交する方向に伸縮可能に設けられており、センサ素子を耳珠側に付勢する。 For example, the blood flow sensor disclosed in Patent Document 1 is applied to an inner ear type headphone, and includes a housing, and an earpiece and a sensor element provided in the housing. When the earpiece is inserted into the ear canal, the sensor element comes into contact with the tragus and blood flow is detected by the sensor element. The sensor element is supported by an elastic body provided in the housing. The elastic body is provided so as to be expandable and contractible in a direction orthogonal to the insertion direction of the earpiece into the ear canal, and urges the sensor element toward the tragus side.

特開２０１３－１４６３７１号公報Japanese Unexamined Patent Publication No. 2013-146371

上述した従来の血流センサは、ハウジングからセンサ素子を突出させる方向に弾性体による付勢力を作用させているため、センサ素子がハウジングに対して移動する構造となっている。このため、この血流センサは、ハウジングとセンサ素子の間に隙間を有しており、この隙間に埃などの異物が侵入する不具合を生じる可能性がある。隙間に埃などの異物が侵入すると、センサ素子のハウジングに対する移動が困難になり、動作不良を引き起こし、血流の検出精度が低下する可能性がある。 The conventional blood flow sensor described above has a structure in which the sensor element moves with respect to the housing because the urging force by the elastic body is applied in the direction of projecting the sensor element from the housing. Therefore, this blood flow sensor has a gap between the housing and the sensor element, and there is a possibility that foreign matter such as dust may enter the gap. If foreign matter such as dust enters the gap, it becomes difficult to move the sensor element to the housing, which may cause malfunction and reduce the detection accuracy of blood flow.

本発明の目的は、生体情報の検出精度を高めることができ、信頼性を向上させることができる生体情報検出装置を提供することである。 An object of the present invention is to provide a biometric information detection device capable of improving the detection accuracy of biometric information and improving the reliability.

本発明の一態様として、生体情報検出装置は、本体部と、前記本体部に固設され、装着者の耳珠の外耳道側の被検出部分に接触する、前記装着者の血流に関する生体情報を検出するための検出部と、前記装着者の耳の耳甲介腔に向けて突出して前記本体部に設けられ、前記耳甲介腔への接触により発生した第１の反力を前記本体部に作用させることによって、前記検出部を前記被検出部分に押し付ける第１の接触部と、前記本体部に対し２つの端部を介して設けられるとともに前記２つの端部のうち一方が他方より前記第１の接触部に近い位置に配置され、前記装着者の耳の対輪に向けて突出し、且つ、前記対輪への接触により発生した第２の反力を前記本体部に作用させることによって、前記検出部を前記被検出部分に押し付ける第２の接触部と、を備える。 As one aspect of the present invention, the biological information detection device is fixed to the main body portion and the main body portion, and is in contact with the detected portion on the external auditory canal side of the wearer's tragus, and the biological information regarding the blood flow of the wearer. A first reaction force generated by contact with the tragus cavity , which is provided on the main body portion so as to project toward the tragus cavity of the wearer's ear, is applied to the main body. A first contact portion that presses the detected portion against the detected portion by acting on the portion, and a first contact portion that is provided with respect to the main body portion via two ends and one of the two ends is provided from the other. A second reaction force that is arranged at a position close to the first contact portion, protrudes toward the pair of ears of the wearer, and is generated by contact with the pair of rings, acts on the main body portion. A second contact portion that presses the detected portion against the detected portion is provided.

本発明の一態様によれば、生体情報の検出精度を高めることができ、信頼性を向上させることができる。 According to one aspect of the present invention, the detection accuracy of biological information can be improved and the reliability can be improved.

以下、本発明の実施形態について図面を参照して説明する。
図１及び図２に示すように、本発明の第１の実施形態に係る生体情報検出装置１０（以下、単に装置１０と称する場合もある）は、挿入部２、押圧部４（接触部、第１の接触部）、係合部６（接触部、第２の接触部）、位置決め部８、及び検出部１を備えている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the biological information detection device 10 (hereinafter, may be simply referred to as a device 10) according to the first embodiment of the present invention has an insertion portion 2 and a pressing portion 4 (contact portion, It includes a first contact portion), an engagement portion 6 (contact portion, a second contact portion), a positioning portion 8, and a detection portion 1.

図３に示すように、装置１０は、検出部１を固設した本体１２（本体部）を有し、本体１２の外側を覆うカバー１４（カバー部）を有する。カバー１４は、エラストマーなどの弾性部材により形成されており、上述した挿入部２、押圧部４、係合部６、及び位置決め部８を含む。つまり、挿入部２、押圧部４、係合部６、及び位置決め部８は、弾性部材によりカバー１４と一体に形成されている。本体１２は、樹脂や金属により形成することができる。 As shown in FIG. 3, the device 10 has a main body 12 (main body portion) in which the detection unit 1 is fixed, and has a cover 14 (cover portion) that covers the outside of the main body 12. The cover 14 is formed of an elastic member such as an elastomer, and includes the above-mentioned insertion portion 2, pressing portion 4, engaging portion 6, and positioning portion 8. That is, the insertion portion 2, the pressing portion 4, the engaging portion 6, and the positioning portion 8 are integrally formed with the cover 14 by the elastic member. The main body 12 can be formed of resin or metal.

カバー１４は、本体１２に対して着脱可能に設けられ、異なるサイズ及び形状の別のカバー１４に交換可能となっている。言い換えると、挿入部２、押圧部４、係合部６、及び位置決め部８の形状や大きさは、カバー１４を交換することにより変更可能であり、本体１２を共通化することができる。 The cover 14 is detachably provided with respect to the main body 12 and can be replaced with another cover 14 having a different size and shape. In other words, the shapes and sizes of the insertion portion 2, the pressing portion 4, the engaging portion 6, and the positioning portion 8 can be changed by exchanging the cover 14, and the main body 12 can be shared.

図３及び図４に示すように、本体１２は、検出部１を埋設している。検出部１は、本体１２の表面１２ａに設けた凹所１２ｂ内に収容配置されている。本体１２の表面１２ａ側の凹所１２ｂの開口部は、透明な板状部材１１により塞がれている。ここで言う板状部材１１は、例えば、透明なガラス板やアクリル板などである。板状部材１１は、これに限らず、例えば、緑色光や赤色光や赤外光を良好に透過可能な素材により形成すればよい。なお、図４では、カバー１４の図示を省略してある。 As shown in FIGS. 3 and 4, the main body 12 has a detection unit 1 embedded therein. The detection unit 1 is housed and arranged in the recess 12b provided on the surface 12a of the main body 12. The opening of the recess 12b on the surface 12a side of the main body 12 is closed by the transparent plate-shaped member 11. The plate-shaped member 11 referred to here is, for example, a transparent glass plate or an acrylic plate. The plate-shaped member 11 is not limited to this, and may be formed of, for example, a material that can satisfactorily transmit green light, red light, or infrared light. In FIG. 4, the cover 14 is not shown.

検出部１は、２つの発光素子１３ａ、１３ｂと１つの受光素子１５を備えている。発光素子１３ａ、１３ｂは、例えばＬＥＤ素子であり、受光素子１５を間に挟んで凹所１２ｂの底に配置されている。発光素子１３ａ、１３ｂから出射された光は、耳で拡散されて、その戻り光が受光素子１５により受光される。この検出部１は、例えば、血流に関する生体情報を検出する反射型の光電式容積脈波（ＰＰＧ；photoplethysmography）センサであり、単位時間当たりの心拍数などを検出する。図１及び図３に示すように、カバー１４は、検出部１の板状部材１１を外部に露出するための開口部１４ａを備えている。 The detection unit 1 includes two light emitting elements 13a and 13b and one light receiving element 15. The light emitting elements 13a and 13b are, for example, LED elements, and are arranged at the bottom of the recess 12b with the light receiving element 15 interposed therebetween. The light emitted from the light emitting elements 13a and 13b is diffused by the ear, and the return light is received by the light receiving element 15. The detection unit 1 is, for example, a reflective photoelectric pulse wave (PPG; photoplethysmography) sensor that detects biological information regarding blood flow, and detects a heart rate or the like per unit time. As shown in FIGS. 1 and 3, the cover 14 includes an opening 14a for exposing the plate-shaped member 11 of the detection unit 1 to the outside.

以下、装置１０の外形及び各部の詳細な構造について、図５乃至図８を参照しながら説明する。装置１０は、人の耳に装着可能であるとともに猿やチンパンジーなどの類人猿の耳に装着可能である。以下の説明では、装置１０を装着した装着者から見て上下左右、前後、内側、外側などを規定する。なお、図５及び図６には、装置１０が装着される一般的な大きさの耳を例示してあるが、図６では、図示明瞭化のため耳の断面を示すハッチングを省略してある。 Hereinafter, the outer shape of the apparatus 10 and the detailed structure of each part will be described with reference to FIGS. 5 to 8. The device 10 can be attached to the ears of a human and can be attached to the ears of apes such as monkeys and chimpanzees. In the following description, up / down / left / right, front / back, inside, outside, etc. are defined from the viewpoint of the wearer who wears the device 10. Note that FIGS. 5 and 6 illustrate an ear of a general size in which the device 10 is mounted, but FIG. 6 omits hatching showing a cross section of the ear for the sake of clarity. ..

挿入部２は、耳の外耳道２１に挿入される。挿入部２は、本体１２からある方向に一体に突設された図示しないプローブとプローブの外側を覆うカバー１４の一部により形成されている。プローブは、例えばその先端に、図示しない温度センサなどを備えてもよい。温度センサとして、例えばサーモパイルやボロメータ素子などがあり、検出対象（例えば、鼓膜やその周辺の皮膚など）から放射される赤外線を非接触で検出して電圧に変換する。装置１０は、温度センサを介して検出した赤外線の強度に基づいて検出対象の温度を測定する。 The insertion portion 2 is inserted into the ear canal 21 of the ear. The insertion portion 2 is formed by a probe (not shown) integrally projecting from the main body 12 in a certain direction and a part of a cover 14 covering the outside of the probe. The probe may be provided with, for example, a temperature sensor (not shown) at its tip. Examples of the temperature sensor include a thermopile and a bolometer element, which detect infrared rays emitted from a detection target (for example, the eardrum and the skin around it) in a non-contact manner and convert them into a voltage. The device 10 measures the temperature of the detection target based on the intensity of infrared rays detected through the temperature sensor.

本体１２に対するプローブ、すなわち挿入部２の角度は、理想的には、挿入部２を所定の深さで外耳道２１に挿入配置した状態（図７に示す状態）で、本体１２に固設した検出部１の板状部材１１の表面が耳珠２２の外耳道２１側の部分２３（以下、この部分を被検出部分２３と称する）に面で接触する角度に設定されている。耳の形には個体差があるため、ここでは平均的な耳の形を図５及び図６に例示して説明するが、例えば、プローブは、耳の形に合わせて、本体１２に対してフレキシブルに折り曲げ可能な構造を有してもよい。 The angle of the probe, that is, the insertion portion 2 with respect to the main body 12 is ideally detected when the insertion portion 2 is inserted and arranged in the ear canal 21 at a predetermined depth (the state shown in FIG. 7) and fixedly attached to the main body 12. The angle at which the surface of the plate-shaped member 11 of the portion 1 comes into contact with the portion 23 of the tragus 22 on the ear canal 21 side (hereinafter, this portion is referred to as a detected portion 23) is set. Since there are individual differences in the shape of the ear, the average shape of the ear will be illustrated and described here with reference to FIGS. 5 and 6. For example, the probe matches the shape of the ear with respect to the main body 12. It may have a structure that can be flexibly bent.

一般に、耳の外耳道２１は外側から内側に向けて斜め上方に傾斜している。これに対し、耳珠裏の被検出部分２３は、その表面を平らな面と仮定した場合、該表面に垂直に交わる線が斜め前方外側に向く角度で傾斜している。つまり、挿入部２の外耳道２１への挿入方向と検出部１の被検出部分２３への押圧方向は異なる方向となる。言い換えると、被検出部分２３は、外耳道２１に対して角度がついている。耳の形には個体差があり、外耳道２１に対する被検出部分２３の角度にも個体差がある。 Generally, the ear canal 21 of the ear is inclined diagonally upward from the outside to the inside. On the other hand, when the surface of the detected portion 23 on the back of the tragus is assumed to be a flat surface, the line perpendicular to the surface is inclined at an angle toward the diagonally forward and outward sides. That is, the insertion direction of the insertion unit 2 into the ear canal 21 and the pressing direction of the detection unit 1 against the detected portion 23 are different directions. In other words, the detected portion 23 is angled with respect to the ear canal 21. There are individual differences in the shape of the ear, and there are also individual differences in the angle of the detected portion 23 with respect to the ear canal 21.

また、外耳道２１を外から見たときに鼓膜（図示せず）が見えることがないため、外耳道２１の入口が耳珠２２により部分的に覆われていることがわかる。よって、外耳道２１に挿入部２を挿入配置しただけで、検出部１の板状部材１１の表面が耳珠裏の被検出部分２３に押し付けられる。 Further, since the eardrum (not shown) cannot be seen when the ear canal 21 is viewed from the outside, it can be seen that the entrance of the ear canal 21 is partially covered by the tragus 22. Therefore, the surface of the plate-shaped member 11 of the detection unit 1 is pressed against the detected portion 23 on the back of the tragus just by inserting and arranging the insertion portion 2 in the ear canal 21.

挿入部２は、カバー１４と一体に形成した２つの略円環状の保持片２ａ、２ｂを略同軸に備えている。２つの保持片２ａ、２ｂは、挿入部２の長手方向に沿って互いに離間して設けられている。２つの保持片２ａ、２ｂは、挿入部２を外耳道２１に挿入した状態で、弾性変形を伴って外耳道２１の内面に接触し、挿入部２の外耳道２１に対する装着状態を安定させる。つまり、２つの保持片２ａ、２ｂは、挿入部２を外耳道２１に対してしっかりと保持せしめて、挿入部２の外耳道２１からの抜けを抑制する。 The insertion portion 2 includes two substantially annular holding pieces 2a and 2b integrally formed with the cover 14 substantially coaxially. The two holding pieces 2a and 2b are provided apart from each other along the longitudinal direction of the insertion portion 2. The two holding pieces 2a and 2b come into contact with the inner surface of the ear canal 21 with elastic deformation in a state where the insertion portion 2 is inserted into the ear canal 21, and stabilize the mounting state of the insertion portion 2 with respect to the ear canal 21. That is, the two holding pieces 2a and 2b firmly hold the insertion portion 2 with respect to the ear canal 21 and suppress the insertion portion 2 from coming off the ear canal 21.

押圧部４は、挿入部２を外耳道２１に挿入した状態（図７）で、耳甲介腔２４に接触する位置に設けられている。押圧部４は、耳甲介腔２４に向けてカバー１４をドーム状に膨出させた形状を有する。押圧部４は、耳甲介腔２４の略全面に接触可能な大きさを有する。押圧部４は、弾性部材を中実にし、或いは内部を空洞にした構造を有する。 The pressing portion 4 is provided at a position in contact with the concha cavity 24 in a state where the insertion portion 2 is inserted into the ear canal 21 (FIG. 7). The pressing portion 4 has a shape in which the cover 14 is bulged in a dome shape toward the concha cavity 24 of the ear. The pressing portion 4 has a size that allows contact with substantially the entire surface of the concha cavity 24. The pressing portion 4 has a structure in which the elastic member is solid or the inside is hollow.

押圧部４は、挿入部２の外耳道２１への挿入により、耳甲介腔２４へ押し付けられ、接触して弾性変形する。この耳甲介腔２４への押圧部４の接触により発生した耳甲介腔２４の反力は、検出部１を耳珠裏の被検出部分２３へ押し付けるように作用する。より詳細には、図８に示すように、押圧部４が受ける耳甲介腔２４の反力Ｆは、挿入部２の本体１２側の根元部分あたりを支点にして本体１２を耳珠２２側に回動（図示矢印Ｒで示す）させるように作用し、それにより、検出部１は被検出部分２３に押し付けられる。このとき、挿入部２が外耳道２１に挿入されているために、挿入部２の根元部分あたりが回動の支点となる。 The pressing portion 4 is pressed against the concha cavity 24 by inserting the inserting portion 2 into the ear canal 21, and is brought into contact with the pressing portion 4 to be elastically deformed. The reaction force of the tragusal cavity 24 generated by the contact of the pressing portion 4 with the tragusal cavity 24 acts to press the detection unit 1 against the detected portion 23 on the back of the tragus. More specifically, as shown in FIG. 8, the reaction force F of the concha space 24 received by the pressing portion 4 is such that the main body 12 is on the tragus 22 side with the root portion of the insertion portion 2 on the main body 12 side as a fulcrum. (Indicated by the arrow R in the figure), the detection unit 1 is pressed against the detected portion 23. At this time, since the insertion portion 2 is inserted into the ear canal 21, the root portion of the insertion portion 2 serves as a fulcrum for rotation.

係合部６は、例えば、棒状の弾性部材をＵ字状に折り曲げたような形状を有する。係合部６は、Ｕ字状に折り曲げた湾曲部分６ａ（対輪側接触部）が本体１２から離間した位置に配置される向きでカバー１４と一体に設けられている。つまり、係合部６は、本体１２側に設けた一端６ｂ及び他端６ｃ（図８）を有し、これら２つの端部６ｂ、６ｃに連なるとともに対輪２５に接触する湾曲部分６ａ（接触部）を有する。 The engaging portion 6 has, for example, a shape in which a rod-shaped elastic member is bent into a U shape. The engaging portion 6 is provided integrally with the cover 14 so that the curved portion 6a (contact portion on the wheel side) bent in a U shape is arranged at a position away from the main body 12. That is, the engaging portion 6 has one end 6b and the other end 6c (FIG. 8) provided on the main body 12 side, and is connected to these two end portions 6b and 6c and has a curved portion 6a (contact) that comes into contact with the pair wheel 25. Part).

挿入部２を外耳道２１に挿入した状態（図７に示す状態）では、係合部６は、弾性変形を伴って、その突出方向の先端にある湾曲部分６ａが、対輪２５と耳甲介艇２６の間に嵌め込まれ、両者２５、２６に接触する。この状態では、係合部６の湾曲部分６ａが対輪２５の内側に配置され、湾曲部分６ａに対輪２５が少なくとも部分的に覆い被さった状態となる。 In the state where the insertion portion 2 is inserted into the ear canal 21 (the state shown in FIG. 7), the engaging portion 6 is elastically deformed, and the curved portion 6a at the tip in the protruding direction thereof is the pair ring 25 and the ear canal. It is fitted between the boats 26 and comes into contact with both 25 and 26. In this state, the curved portion 6a of the engaging portion 6 is arranged inside the pair of wheels 25, and the curved portion 6a is at least partially covered with the curved portion 25.

また、図７に示す状態では、湾曲部分６ａが対輪２５と耳甲介艇２６の間に嵌め込まれ、両者に接触することで、係合部６が弾性変形する。この対輪２５及び耳甲介艇２６への係合部６の接触により発生した対輪２５及び耳甲介艇２６の反力は、検出部１を耳珠裏の被検出部分２３へ押し付けるように作用する。このとき、係合部６が受ける対輪２５及び耳甲介艇２６の反力は、前述した耳甲介腔２４の反力Ｆと同様、挿入部２の根元部分あたりを支点として本体１２を回動させるように作用する。 Further, in the state shown in FIG. 7, the curved portion 6a is fitted between the pair of wheels 25 and the ear condyle boat 26, and when they come into contact with each other, the engaging portion 6 is elastically deformed. The reaction force of the anti-wheel 25 and the tragus 26 generated by the contact of the engaging portion 6 with the anti-wheel 25 and the tragus 26 causes the detection unit 1 to be pressed against the detected portion 23 on the back of the tragus. Acts on. At this time, the reaction force of the pair of wheels 25 and the ear shell boat 26 received by the engaging portion 6 is the same as the reaction force F of the ear shell cavity 24 described above, with the main body 12 as a fulcrum around the root portion of the insertion portion 2. It acts to rotate.

係合部６を弾性変形可能な材料により形成することで、係合部６を対輪２５から外れさせることなく、対輪２５（及び耳甲介艇２６）の反力を本体１２に作用させることができ、検出部１を被検出部分２３に押し付けることができる。 By forming the engaging portion 6 with a material that can be elastically deformed, the reaction force of the pairing ring 25 (and the earcaps 26) acts on the main body 12 without disengaging the engaging portion 6 from the pair of wheels 25. This allows the detection unit 1 to be pressed against the detected portion 23.

耳の形状や大きさには個体差があり、係合部６の湾曲部分６ａが耳甲介艇２６に奥まで嵌らない場合もある。例えば、比較的大きな耳に装置１０を装着し、挿入部２を外耳道２１に挿入した状態では、湾曲部分６ａに対輪２５がわずかに引っ掛かった状態となり、湾曲部分６ａが耳甲介艇２６に届かない場合も考えられる。このような場合、係合部６は、対輪２５に接触することで弾性変形する。この対輪２５への係合部６の接触により発生した対輪２５の反力は、上述した場合と同様に、挿入部２の根元あたりを支点として本体１２を回動させるように作用し、それにより、検出部１は被検出部分２３に押し付けられる。 There are individual differences in the shape and size of the ears, and the curved portion 6a of the engaging portion 6 may not fit all the way into the instep boat 26. For example, when the device 10 is attached to a relatively large ear and the insertion portion 2 is inserted into the ear canal 21, the pair wheel 25 is slightly caught on the curved portion 6a, and the curved portion 6a is attached to the ear canal boat 26. It may not reach. In such a case, the engaging portion 6 is elastically deformed by coming into contact with the pair of wheels 25. The reaction force of the pair of wheels 25 generated by the contact of the engagement portion 6 with the pair of wheels 25 acts to rotate the main body 12 with the root of the insertion portion 2 as a fulcrum, as in the case described above. As a result, the detection unit 1 is pressed against the detection unit 23.

いずれにしても、本実施形態によると、係合部６は、対輪２５及び耳甲介艇２６に、又は、対輪２５のみに、接触し、それにより発生した対輪２５及び耳甲介艇２６の反力は、本体１２を介して、検出部１を被検出部分２３に押し付けるように作用する。 In any case, according to the present embodiment, the engaging portion 6 comes into contact with the pair of wheels 25 and the earpiece boat 26, or only with the pair of wheels 25, and the pair of wheels 25 and the earpiece are generated thereby. The reaction force of the boat 26 acts to press the detection unit 1 against the detected portion 23 via the main body 12.

なお、検出部１を被検出部分２３へ良好に押し付けるため、係合部６の両端６ｂ、６ｃは、図２及び図８に示すように、挿入部２に近い側（装着者の外耳道側）の一端６ｂが他端６ｃより耳甲介腔２４に近い位置に（押圧部４に近い位置に）配置されるように、カバー１４と一体に設けられている。言い換えると、係合部６の両端６ｂ、６ｃを結んだ架空の線Ｌ（図８）が検出部１の板状部材１１の表面に対して傾斜する角度で係合部６が設けられている。これにより、対輪２５及び耳甲介艇２６の反力を、係合部６及び本体１２を介して被検出部分２３に良好に作用させることができ、検出部１を被検出部分２３に確実に押し付けることができる。 In order to satisfactorily press the detection portion 1 against the detection portion 23, both ends 6b and 6c of the engagement portion 6 are on the side close to the insertion portion 2 (the ear canal side of the wearer) as shown in FIGS. 2 and 8. Is provided integrally with the cover 14 so that one end 6b of the above is arranged closer to the concha cavity 24 than the other end 6c (closer to the pressing portion 4). In other words, the engaging portion 6 is provided at an angle at which an imaginary line L (FIG. 8) connecting both ends 6b and 6c of the engaging portion 6 is inclined with respect to the surface of the plate-shaped member 11 of the detecting portion 1. .. As a result, the reaction force of the pair of wheels 25 and the instep boat 26 can be satisfactorily applied to the detected portion 23 via the engaging portion 6 and the main body 12, and the detected portion 1 can be reliably applied to the detected portion 23. Can be pressed against.

係合部６は、棒状の弾性部材をＵ字状に折り曲げた形状に限らず、棒状の弾性部材を「く」の字に折り曲げた形状などであってもよく、弾性変形した際の反力により検出部１を被検出部分２３へ押し付ける方向の力を発生することができる形状であればよい。いずれにしても、係合部６は、検出部１を被検出部分２３に良好に押し付けるため、その突出長さを、挿入部２の本体１２に対する突出長さより長くすることが望ましい。 The engaging portion 6 is not limited to a shape in which a rod-shaped elastic member is bent into a U shape, but may be a shape in which a rod-shaped elastic member is bent into a “dogleg” shape, and the reaction force when elastically deformed. Any shape may be used as long as it can generate a force in the direction of pressing the detected portion 1 against the detected portion 23. In any case, in order for the engaging portion 6 to satisfactorily press the detected portion 1 against the detected portion 23, it is desirable that the protruding length thereof is longer than the protruding length of the inserting portion 2 with respect to the main body 12.

上述したように、押圧部４及び係合部６は、検出部１を被検出部分２３へ押し付けるための接触部として機能する。よって、押圧部４及び係合部６のいずれか一方のみを設けた場合であっても検出部１を被検出部分２３へ良好に押し付けることができるが、押圧部４及び係合部６の両方を設けた場合には、押圧部４及び係合部６の一方を設けた場合と比較して、検出部１を被検出部分２３へより確実に押し付けることができる。 As described above, the pressing portion 4 and the engaging portion 6 function as contact portions for pressing the detected portion 1 against the detected portion 23. Therefore, even if only one of the pressing portion 4 and the engaging portion 6 is provided, the detected portion 1 can be satisfactorily pressed against the detected portion 23, but both the pressing portion 4 and the engaging portion 6 are provided. Is provided, the detection unit 1 can be more reliably pressed against the detected portion 23 as compared with the case where one of the pressing portion 4 and the engaging portion 6 is provided.

位置決め部８は、挿入部２を外耳道２１に挿入した状態で、耳珠２２と対珠２７の間の珠間切痕２８に接触する位置に設けられている。言い換えると、位置決め部８は、本体１２に対し、挿入部２を外耳道２１に挿入した状態で、位置決め部８が珠間切痕２８に嵌め込まれる位置及び角度で設けられている。位置決め部８は、本体１２から所定方向に真っ直ぐに延びたカバー１４と一体の突起である。 The positioning portion 8 is provided at a position where the insertion portion 2 is inserted into the ear canal 21 and is in contact with the intertragic notch 28 between the tragus 22 and the tragus 27. In other words, the positioning portion 8 is provided with respect to the main body 12 at a position and angle at which the positioning portion 8 is fitted into the intertragic notch 28 with the insertion portion 2 inserted into the ear canal 21. The positioning portion 8 is a protrusion integrated with the cover 14 extending straight from the main body 12 in a predetermined direction.

位置決め部８は、挿入部２の外耳道２１への挿入により、珠間切痕２８に嵌め込まれ、接触して弾性変形する。この珠間切痕２８への位置決め部８の接触により発生した珠間切痕２８の反力は、検出部１を耳珠裏の被検出部分２３に押し付けるように作用する。より詳細には、珠間切痕２８の反力は、本体１２を左耳に装着した場合には、本体１２を装着者の頭から左に離す方向に作用し、換言すれば、前述した耳甲介腔２４の反力Ｆと同様、挿入部２の根元部分あたりを支点として本体１２を回動させるように作用し、それにより、検出部１は被検出部分２３に押し付けられる。また、位置決め部８は、珠間切痕２８に嵌め込まれることで、装置１０を耳に対して位置決めする機能を有する。 The positioning portion 8 is fitted into the intertragic notch 28 by inserting the insertion portion 2 into the ear canal 21, and is brought into contact with the positioning portion 8 to be elastically deformed. The reaction force of the intertragic notch 28 generated by the contact of the positioning portion 8 with the intertragic notch 28 acts to press the detection unit 1 against the detected portion 23 on the back of the tragus. More specifically, the reaction force of the intertragic notch 28 acts in a direction in which the main body 12 is separated from the wearer's head to the left when the main body 12 is attached to the left ear, in other words, the above-mentioned ear plate. Similar to the reaction force F of the cavity 24, the main body 12 acts to rotate around the root portion of the insertion portion 2, whereby the detection portion 1 is pressed against the detected portion 23. Further, the positioning unit 8 has a function of positioning the device 10 with respect to the ear by being fitted into the intertragic notch 28.

上述した押圧部４及び係合部６に加えて位置決め部８を備えることにより、装置１０を耳に対してよりフィットさせて装着することができ、検出部１をさらに確実に耳珠裏の被検出部分２３へ押し付けることができる。しかし、位置決め部８は、本発明に必須の構成ではなく、図９に示す変形例のように、位置決め部８を省略してもよい。また、上述したように、押圧部４及び係合部６は、少なくとも一方を備えていればよく、必ずしも両方を備えている必要はない。 By providing the positioning portion 8 in addition to the pressing portion 4 and the engaging portion 6 described above, the device 10 can be fitted to the ear more closely and the detection portion 1 can be more reliably covered by the back of the tragus. It can be pressed against the detection portion 23. However, the positioning unit 8 is not an essential configuration in the present invention, and the positioning unit 8 may be omitted as in the modified example shown in FIG. Further, as described above, the pressing portion 4 and the engaging portion 6 need only include at least one, and does not necessarily have to include both.

以上のように、本実施形態によると、耳珠裏の被検出部分２３に検出部１を押し付けるための接触部として、押圧部４と係合部６を備えているため、検出部１をより確実に被検出部分２３に押し付けることができ、ひいては、血流の検出精度を高めることができる。よって、本実施形態によると、血流の検出に対する信頼性を向上させることができる。つまり、本実施形態の装置１０は、検出部１を本体１２に固定した構造を有し、本体１２に対して検出部１を移動させる機構を持たないため、検出部１と本体１２の間に不所望な隙間が無く、隙間に埃などの異物が入って動作不良を生じることがない。 As described above, according to the present embodiment, since the pressing portion 4 and the engaging portion 6 are provided as the contact portion for pressing the detection portion 1 against the detected portion 23 on the back of the tragus, the detection portion 1 is further attached. It can be reliably pressed against the detected portion 23, and thus the detection accuracy of blood flow can be improved. Therefore, according to the present embodiment, the reliability for detecting blood flow can be improved. That is, since the device 10 of the present embodiment has a structure in which the detection unit 1 is fixed to the main body 12 and does not have a mechanism for moving the detection unit 1 with respect to the main body 12, there is no mechanism between the detection unit 1 and the main body 12. There are no undesired gaps, and foreign matter such as dust does not enter the gaps and cause malfunction.

上述した本実施形態の効果は、押圧部４と係合部６の両方を備えることでより高まるが、押圧部４と係合部６のいずれか一方を備えるだけであっても効果を奏することができる。さらに、位置決め部８を備えることで、装置１０の耳への位置決め機能に加え、検出部１を被検出部分２３へ押し付ける機能を加えることができ、検出精度をより高めることができる。 The effect of the present embodiment described above is further enhanced by providing both the pressing portion 4 and the engaging portion 6, but the effect can be obtained even if only one of the pressing portion 4 and the engaging portion 6 is provided. Can be done. Further, by providing the positioning unit 8, in addition to the function of positioning the device 10 on the ear, a function of pressing the detection unit 1 against the detected portion 23 can be added, and the detection accuracy can be further improved.

また、本実施形態のように、押圧部４と係合部６の両方を備えた装置１０では、検出部１を被検出部分２３へ押し付ける力を、耳甲介腔２４から押圧部４が受ける反力と、対輪２５及び耳甲介艇２６から係合部６が受ける反力との合力により発生させることができる。このため、見方を変えると、検出部１を被検出部分２３に押し付けるために、耳甲介腔２４、対輪２５、及び耳甲介艇２６のそれぞれに装置１０から加えられる押圧力（反力）を分散させて小さくすることができ、装置１０を耳に長時間装着した場合であっても、装着者が痛みを感じる不具合を生じ難くすることができる。 Further, in the device 10 provided with both the pressing portion 4 and the engaging portion 6, as in the present embodiment, the pressing portion 4 receives the force for pressing the detection portion 1 against the detected portion 23 from the concha cavity 24. It can be generated by the resultant force of the reaction force and the reaction force received by the engaging portion 6 from the pair wheel 25 and the instep boat 26. Therefore, from a different point of view, the pressing force (reaction force) applied from the device 10 to each of the concha cavity 24, the pair of wheels 25, and the concha boat 26 in order to press the detection unit 1 against the detected portion 23. ) Can be dispersed and made smaller, and even when the device 10 is worn on the ear for a long time, it is possible to prevent the wearer from feeling pain.

また、本実施形態のように、検出部１を被検出部分２３に押し付けるための接触部として押圧部４と係合部６を備えることで、耳の形や大きさに個体差があっても、装置１０を耳にしっかりと装着し易くすることができる。つまり、押圧部４と係合部６の一方が耳に密着しない場合であっても、他方が耳に密着すればよく、耳の形状のバラつきや大きさの違いを吸収し易くすることができる。 Further, as in the present embodiment, by providing the pressing portion 4 and the engaging portion 6 as the contact portion for pressing the detected portion 1 against the detected portion 23, even if there are individual differences in the shape and size of the ears. , The device 10 can be firmly attached to the ear. That is, even if one of the pressing portion 4 and the engaging portion 6 does not come into close contact with the ear, the other may come into close contact with the ear, and it is possible to easily absorb variations in the shape and size of the ear. ..

例えば、押圧部４と係合部６の一方を耳が比較的大きい装着者に合わせて、他方を耳が比較的小さい装着者に合わせることで、耳の大きさの個体差を許容することができ、カバー１４を耳の大きさに合わせて複数種類用意する必要が無くなる。 For example, by matching one of the pressing portion 4 and the engaging portion 6 to a wearer having a relatively large ear and the other to a wearer having a relatively small ear, it is possible to allow individual differences in ear size. This eliminates the need to prepare multiple types of covers 14 according to the size of the ear.

言い換えると、押圧部４と係合部６の一方のみを備えた装置１０であっても、耳の形状の違いや大きさの違いに合わせて複数種類のカバー１４を予め用意すればよく、装着者に合ったカバー１４を選択して本体１２に被せればよい。 In other words, even in the device 10 provided with only one of the pressing portion 4 and the engaging portion 6, a plurality of types of covers 14 may be prepared in advance according to the difference in the shape and size of the ears, and the cover 14 may be attached. The cover 14 suitable for the person may be selected and put on the main body 12.

Then, the pressing portion 4, the engaging portion 6, and the positioning portion 8 may be provided integrally with the main body 12. In this case, the main body itself may be formed of a member that can be elastically deformed, or the pressing portion 4, the engaging portion 6, and the positioning portion 8 may be formed of, for example, a rigid body that is difficult to elastically deform. In the latter case, the device 10 can be attached to the ear by deforming the ear according to the shapes of the pressing portion 4, the engaging portion 6, and the positioning portion 8.

また、上述した実施形態では、押圧部４、係合部６、及び位置決め部８の全体を弾性部材により形成した場合について説明したが、これに限らず、押圧部４、係合部６、及び位置決め部８が耳に接触する部分や、本体１２との間の付け根部分だけ弾性を持たせてもよい。 Further, in the above-described embodiment, the case where the pressing portion 4, the engaging portion 6, and the positioning portion 8 are entirely formed of the elastic member has been described, but the present invention is not limited to this, and the pressing portion 4, the engaging portion 6, and the positioning portion 8 are not limited to this. Only the portion where the positioning portion 8 comes into contact with the ear and the portion at the base between the positioning portion 8 and the main body 12 may have elasticity.

さらに、上述した実施形態では、血流に関する生体情報を検出する検出部１や温度センサを備えた装置１０について説明したが、これに限らず、このような検出手段を持たないイヤホンなどのヒアラブルデバイスに本願発明を適用することもできる。また、このような検出手段を持ったイヤホンなどのヒアラブルデバイスに本願発明を適用することもできる。 Further, in the above-described embodiment, the detection unit 1 for detecting biological information regarding blood flow and the device 10 provided with a temperature sensor have been described, but the present invention is not limited to this, and a hearable such as an earphone having no such detection means is described. The present invention can also be applied to the device. Further, the present invention can also be applied to a hearable device such as an earphone having such a detection means.

以下、本発明の第２の実施形態に係る生体情報検出装置３０について、図１０～図１２を参照して説明する。なお、ここでは、上述した第１の実施形態と同様に機能する構成要素には、同一符号を付してその詳細な説明を省略する。 Hereinafter, the biological information detection device 30 according to the second embodiment of the present invention will be described with reference to FIGS. 10 to 12.

図１１に示すように、装置３０は、検出部１を固設した本体３２、カバー３４、及びキャップ３６を有する。本体３２は、プローブ３８を有する。カバー３４は、本体３２の一部を外側から覆い、キャップ３６は、カバー３４から突出したプローブ３８の先端に取り付けられる。つまり、プローブ３８を覆うように本体３２にカバー３４を被せ、カバー３４から突出したプローブ３８の先端にキャップ３６を装着することによって装置３０が組み立てられる。 As shown in FIG. 11, the device 30 has a main body 32, a cover 34, and a cap 36 on which the detection unit 1 is fixed. The main body 32 has a probe 38. The cover 34 covers a part of the main body 32 from the outside, and the cap 36 is attached to the tip of the probe 38 protruding from the cover 34. That is, the device 30 is assembled by covering the main body 32 with the cover 34 so as to cover the probe 38 and attaching the cap 36 to the tip of the probe 38 protruding from the cover 34.

本体３２は、第１部材３２ａと第２部材３２ｂを有する。第１部材３２ａは、筐体状に形成され、第１部材３２ａの耳珠裏側の面には、検出部１が取り付けられている。第１部材３２ａの内側には、検出部１に接続された基板や配線（いずれも図示せず）が収容されている。第２部材３２ｂは、第１部材３２ａと同様に筐体状に形成されている。第２部材３２ｂの内側には、第１部材３２ａから外方に延びる検出部１の配線が収容されている。第１及び第２部材３２ａ、３２ｂは、例えば、樹脂や金属により形成されている。本体３２は、第２部材３２ｂを第１部材３２ａに重ねてネジ３３により固定することによって組み立てられている。 The main body 32 has a first member 32a and a second member 32b. The first member 32a is formed in a housing shape, and the detection unit 1 is attached to the surface of the first member 32a on the back side of the tragus. Inside the first member 32a, a substrate and wiring (none of which are shown) connected to the detection unit 1 are housed. The second member 32b is formed in a housing shape like the first member 32a. Inside the second member 32b, the wiring of the detection unit 1 extending outward from the first member 32a is housed. The first and second members 32a and 32b are made of, for example, resin or metal. The main body 32 is assembled by superimposing the second member 32b on the first member 32a and fixing it with a screw 33.

カバー３４は、本体３２の第１部材３２ａを外側から覆うように本体３２に対して着脱可能に取り付けられている。押圧部４’及び係合部６は、カバー３４と一体に設けられている。カバー３４は、検出部１を露出させるための窓部３４ａを有する。カバー３４は、例えばエラストマーなどの弾性部材により形成されている。 The cover 34 is detachably attached to the main body 32 so as to cover the first member 32a of the main body 32 from the outside. The pressing portion 4'and the engaging portion 6 are provided integrally with the cover 34. The cover 34 has a window portion 34a for exposing the detection portion 1. The cover 34 is formed of an elastic member such as an elastomer.

キャップ３６は、略円筒形状を有し、本体３２のプローブ３８の先端に嵌合して取り付けられる。キャップ３６は、例えばウレタン系エラストマー、シリコン系エラストマー、フッ素系エラストマーなどにより形成されている。キャップ３６は、耳の外耳道２１に挿入する挿入部２として機能する。キャップ３６と検出部１の間のカバー３４の部分は、外耳道２１の入口付近に収まる部分であり、挿入部２の一部とみなすこともできる。本体３２の第２部材３２ｂは、耳の珠間切痕２８に嵌る位置決め部８として機能する。位置決め部８は、本体３２の一部であり、カバー３４を含まない。 The cap 36 has a substantially cylindrical shape and is fitted and attached to the tip of the probe 38 of the main body 32. The cap 36 is formed of, for example, a urethane-based elastomer, a silicon-based elastomer, a fluorine-based elastomer, or the like. The cap 36 functions as an insertion portion 2 to be inserted into the ear canal 21 of the ear. The portion of the cover 34 between the cap 36 and the detection portion 1 is a portion that fits near the entrance of the ear canal 21 and can be regarded as a part of the insertion portion 2. The second member 32b of the main body 32 functions as a positioning portion 8 that fits into the intertragic notch 28 of the ear. The positioning portion 8 is a part of the main body 32 and does not include the cover 34.

図１２に示すように、押圧部４’は、カバー３４の一部をドーム状に膨出させた形状を有し、内部を空洞或いは中実にした構造を有する。押圧部４’の構造及び機能については後に詳述する。係合部６は、挿入部２を外耳道２１に挿入した状態で耳甲介艇２６に向かう方向に傾斜して延設されている。 As shown in FIG. 12, the pressing portion 4'has a shape in which a part of the cover 34 is bulged in a dome shape, and has a structure in which the inside is hollow or solid. The structure and function of the pressing portion 4'will be described in detail later. The engaging portion 6 is extended so as to be inclined in the direction toward the instep vessel 26 with the insertion portion 2 inserted in the ear canal 21.

上記構造の装置３０は、上述した第１の実施形態の装置１０と同様に耳に装着される。つまり、外耳道２１に挿入部２を挿入し、押圧部４’を耳甲介腔２４に押し当てて、係合部６を対輪２５と耳甲介艇２６の間に挿入し、位置決め部８を耳珠２２と対珠２７の間の珠間切痕２８に配置する。 The device 30 having the above structure is attached to the ear in the same manner as the device 10 of the first embodiment described above. That is, the insertion portion 2 is inserted into the ear canal 21, the pressing portion 4'is pressed against the tragus cavity 24, the engaging portion 6 is inserted between the pair wheel 25 and the tragus boat 26, and the positioning portion 8 is used. Is placed in the intertragic notch 28 between the tragus 22 and the pair 27.

本実施形態によると、上述した第１の実施形態と同様に、装置３０が押圧部４’、係合部６、及び位置決め部８を備えているため、装置３０を耳に対してフィットさせて装着することができる。装置３０を耳に装着すると、押圧部４’が耳甲介腔２４の反力を受け、係合部６が対輪２５と耳甲介艇２６の反力を受け、且つ位置決め部８が珠間切痕２８の反力を受ける。これらの反力は、挿入部２の本体３２側の根元部分あたりを支点にして本体３２を回動させ、検出部１を耳珠裏の被検出部分２３に押し付ける。 According to the present embodiment, as in the first embodiment described above, since the device 30 includes the pressing portion 4', the engaging portion 6, and the positioning portion 8, the device 30 is fitted to the ear. Can be attached. When the device 30 is attached to the ear, the pressing portion 4'receives the reaction force of the concha cavity 24, the engaging portion 6 receives the reaction force of the pair wheel 25 and the concha boat 26, and the positioning portion 8 receives the intertragic bead. Receives the reaction force of the notch 28. These reaction forces rotate the main body 32 around the root portion of the insertion portion 2 on the main body 32 side as a fulcrum, and press the detection portion 1 against the detected portion 23 on the back of the tragus.

本実施形態の装置３０を用いた場合、上述した第１の実施形態の装置１０と同様の効果を奏することができ、血流の検出精度を高めることができ、信頼性を向上させることができる。さらに、本実施形態の装置３０は、上述した第１の実施形態の装置１０と比較して、耳の大きさの違いをより広い範囲で許容することができ、サイズの異なるより多くの耳にフィットさせることができる。 When the device 30 of the present embodiment is used, the same effect as that of the device 10 of the first embodiment described above can be obtained, the blood flow detection accuracy can be improved, and the reliability can be improved. .. Further, the device 30 of the present embodiment can tolerate a wider range of differences in ear size as compared with the device 10 of the first embodiment described above, and can be applied to more ears of different sizes. Can be fitted.

以下、図１２～図１８を参照して、上述した第２の実施形態に係る生体情報検出装置３０の押圧部４’の形状及び機能について、第１の実施形態の装置１０と比較して説明する。なお、図１３～図１８では、図示明瞭化のため、耳の断面を示すハッチングの図示を省略している。 Hereinafter, with reference to FIGS. 12 to 18, the shape and function of the pressing portion 4'of the biological information detection device 30 according to the second embodiment described above will be described in comparison with the device 10 of the first embodiment. do. In FIGS. 13 to 18, the hatching showing the cross section of the ear is omitted for the sake of clarity.

まず、押圧部４’の形状について説明する。
図１２に示すように、押圧部４’は、前述したようにドーム状に膨出した形状を有し、耳甲介腔２４側への突出高さが最も高い頂部４０を有する。装置３０の押圧部４’が耳甲介腔２４に向けて膨出した部分の体積は、同じ大きさの装置１０の押圧部４が膨出した部分の体積より小さい。押圧部４’の頂部４０は、本体３２の下側の部位に対応するように配置され、第１の実施形態の装置１０の押圧部４のそれと比較して、下方にずれた位置にある。ここで言う「下側」及び「下方」とは、装置３０を耳に装着した装着者からみた場合の方向であり、装置３０を耳に装着した状態で概ね係合部６から位置決め部８に向かう方向である。言い換えると、装置３０の押圧部４’は、挿入部２を外耳道２１に挿入した状態で、その頂部４０が耳甲介腔２４の略中央から下方にずれた位置で耳甲介腔２４に接触する形状を有する。 First, the shape of the pressing portion 4'will be described.
As shown in FIG. 12, the pressing portion 4'has a dome-shaped bulging shape as described above, and has a top portion 40 having the highest protrusion height toward the ear condyle cavity 24 side. The volume of the portion where the pressing portion 4'of the device 30 bulges toward the concha cavity 24 is smaller than the volume of the portion where the pressing portion 4 of the device 10 having the same size bulges. The top 40 of the pressing portion 4'is arranged so as to correspond to the lower portion of the main body 32, and is positioned downwardly as compared with that of the pressing portion 4 of the device 10 of the first embodiment. The "lower side" and "lower side" referred to here are directions when viewed from the wearer who wears the device 30 on the ear, and from the engaging portion 6 to the positioning portion 8 while the device 30 is worn on the ear. The direction to go. In other words, the pressing portion 4'of the device 30 contacts the concha cavity 24 at a position where the top 40 thereof is displaced downward from the substantially center of the concha cavity 24 in a state where the insertion portion 2 is inserted into the ear canal 21. Has a shape to be used.

すなわち、押圧部４’の頂部４０は、第１の実施形態の装置１０の押圧部４の頂部よりも、係合部６から離れた位置にある。さらに言い換えると、第１の実施形態の装置１０の押圧部４の頂部が本体１２の上下方向の中心にあると想定した場合、このように押圧部４’の頂部４０が下方にずれている点において、第２の実施形態の装置３０は、第１の実施形態の装置１０と異なる。 That is, the top 40 of the pressing portion 4'is located at a position farther from the engaging portion 6 than the top of the pressing portion 4 of the device 10 of the first embodiment. In other words, assuming that the top of the pressing portion 4 of the apparatus 10 of the first embodiment is at the center of the main body 12 in the vertical direction, the top 40 of the pressing portion 4'is displaced downward in this way. In, the apparatus 30 of the second embodiment is different from the apparatus 10 of the first embodiment.

次に、押圧部４’の機能について、第１の実施形態の装置１０の押圧部４と比較して説明する。 Next, the function of the pressing portion 4'will be described in comparison with the pressing portion 4 of the apparatus 10 of the first embodiment.

図１３に示すように、一般的な大きさの耳に第１の実施形態の装置１０を装着すると、挿入部２を所定量で外耳道２１に挿入した状態で、押圧部４の全体が耳甲介腔２４に密着し易く、係合部６も対輪２５と耳甲介艇２６の間に挿入し易い。言い換えると、第１の実施形態の装置１０は、挿入部２を外耳道２１に適切な状態で挿入することで、押圧部４を耳甲介腔２４に隙間無く密着させることができ、且つ係合部６を対輪２５と耳甲介艇２６の間に適切に挿入配置することができる形状を有する。 As shown in FIG. 13, when the device 10 of the first embodiment is attached to an ear of a general size, the entire pressing portion 4 is in the ear canal with the insertion portion 2 inserted into the external auditory canal 21 in a predetermined amount. It is easy to adhere to the cavity 24, and the engaging portion 6 is also easy to be inserted between the pair of wheels 25 and the ear canal boat 26. In other words, in the device 10 of the first embodiment, by inserting the insertion portion 2 into the external auditory canal 21 in an appropriate state, the pressing portion 4 can be brought into close contact with the concha cavity 24 without a gap, and is engaged. The portion 6 has a shape that can be appropriately inserted and arranged between the pair of wheels 25 and the ear canal boat 26.

しかし、上記のように一般的な大きさの耳にフィットするように設計した装置１０を、図１４に示すような比較的小さな耳に装着した場合、装置１０が耳にフィットし難くなる可能性がある。この場合、係合部６の変形量を大きくして対輪２５と耳甲介艇２６の間に押し込むことで、装置１０を耳に装着することも可能であるが、装置１０が使用中に耳から脱落し易く、長時間装着した際に耳が痛くなる可能性がある。 However, if the device 10 designed to fit a general size ear as described above is attached to a relatively small ear as shown in FIG. 14, the device 10 may not fit the ear easily. There is. In this case, it is possible to attach the device 10 to the ear by increasing the amount of deformation of the engaging portion 6 and pushing it between the pair wheel 25 and the earcaps 26, but the device 10 is in use. It is easy to fall off from the ear and may hurt the ear when worn for a long time.

このような不具合を解消するため、図１５に示すように、比較的小さな耳に合わせて装置１０のサイズを全体的に小さくする方法が考えられる。この場合、耳の大きさに合わせてサイズの異なる複数種類の装置１０を用意すればよい。しかし、この場合、サイズの異なる複数種類の装置１０を製造する必要があり、サイズ毎に製造ラインを変える必要があり、在庫の管理が煩雑であり、その分、作業負担が増大し、製造コストが高くなる要因となる。 In order to eliminate such a problem, as shown in FIG. 15, a method of reducing the size of the device 10 as a whole to fit a relatively small ear can be considered. In this case, a plurality of types of devices 10 having different sizes according to the size of the ear may be prepared. However, in this case, it is necessary to manufacture a plurality of types of devices 10 having different sizes, it is necessary to change the manufacturing line for each size, inventory management is complicated, the work load is increased by that amount, and the manufacturing cost is increased. Is a factor that increases.

このため、一般的な大きさの耳に対して装置１０のサイズを小さ目に設計して、大きさの異なる全ての耳に装着可能にする方法が考えられる。しかし、この場合、図１６に示すように、一般的な大きさの耳に小さ目に設計した装置１０’を装着すると、挿入部２を外耳道２１に対して所定深さで挿入することができなくなり、押圧部４と耳甲介腔２４との間に隙間が生じ、係合部６が対輪２５と耳甲介艇２６の間まで届かなくなる可能性がある。 Therefore, a method is conceivable in which the size of the device 10 is designed to be smaller than that of an ear having a general size so that the device 10 can be attached to all ears having different sizes. However, in this case, as shown in FIG. 16, if a device 10'designed to be small is attached to an ear of a general size, the insertion portion 2 cannot be inserted into the ear canal 21 at a predetermined depth. , There is a possibility that a gap is created between the pressing portion 4 and the ear canal cavity 24, and the engaging portion 6 does not reach between the pair wheel 25 and the ear canal boat 26.

よって、本実施形態では、装置３０の全体的な大きさは装置１０に対して小型化せずに、押圧部４’の頂部４０を下方にずらすことで、大きさの異なる全ての耳に装置３０を装着可能とした。 Therefore, in the present embodiment, the overall size of the device 30 is not reduced with respect to the device 10, but by shifting the top 40 of the pressing portion 4'downward, the device is applied to all ears having different sizes. 30 can be attached.

例えば、図１７に示すように、装置１０と同じ大きさの装置３０を比較的小さな耳に装着すると、押圧部４’が耳甲介腔２４に向けて膨出した部分の体積が装置１０と比較して小さい分、押圧部４’が耳甲介腔２４に密着し易くなり、装置３０が耳にフィットする。この場合、装置３０は、挿入部２の本体３２側の根元部分あたりを中心に図１７で時計回り方向にわずかに回動し、押圧部４’と耳甲介腔２４の間の隙間を小さくし、押圧部４’が耳甲介腔２４により密着し易くなる。図１７における「時計回り方向」は、装置３０を耳に装着した装着者からみて前後方向に延び且つ上述した根元部分あたりを通る架空の軸線を中心として、係合部６が頭部に近付く方向に装置３０が回動する図示矢印方向である。 For example, as shown in FIG. 17, when the device 30 having the same size as the device 10 is attached to a relatively small ear, the volume of the portion where the pressing portion 4'bulges toward the concha cavity 24 becomes the device 10. Since the pressing portion 4'is smaller than the other, it becomes easier for the pressing portion 4'to come into close contact with the concha cavity 24, and the device 30 fits the ear. In this case, the device 30 slightly rotates clockwise in FIG. 17 around the root portion of the insertion portion 2 on the main body 32 side to reduce the gap between the pressing portion 4'and the ear condyle cavity 24. However, the pressing portion 4'is more likely to be in close contact with the concha cavity 24. The “clockwise direction” in FIG. 17 is a direction in which the engaging portion 6 approaches the head with a fictitious axis extending in the front-rear direction and passing around the above-mentioned root portion when viewed from the wearer wearing the device 30 on the ear. In the direction of the arrow in the figure in which the device 30 rotates.

一方、図１８に示すように、一般的な大きさの耳に同じ大きさの装置３０を装着すると、頂部４０を下方にずらした分、押圧部４’の上方で耳甲介腔２４との間に隙間が形成される。この隙間の存在により、第１の実施形態の装置１０と比較して、装置３０が図１８で時計回り方向に回動し易くなることが想定される。図１８における「時計回り方向」は、装置３０を耳に装着した装着者からみて前後方向に延び且つ上述した根元部分あたりを通る架空の軸線を中心として、係合部６が頭部に近付く方向に装置３０が回動する方向である。 On the other hand, as shown in FIG. 18, when the device 30 of the same size is attached to an ear of a general size, the apex 40 is shifted downward, and the ear condyle cavity 24 is located above the pressing portion 4'. A gap is formed between them. It is assumed that the presence of this gap makes it easier for the device 30 to rotate clockwise in FIG. 18 as compared to the device 10 of the first embodiment. The "clockwise direction" in FIG. 18 is the direction in which the engaging portion 6 approaches the head with the fictitious axis extending in the front-rear direction as viewed from the wearer wearing the device 30 to the ear and passing around the above-mentioned root portion. This is the direction in which the device 30 rotates.

しかし、頂部４０を下方にずらした押圧部４’が耳甲介腔２４の下方の面にフィットし、さらに、挿入部２が外耳道２１に所定深さで挿入され、且つ係合部６が対輪２５と耳甲介艇２６の間に押し込まれるため、時計回り方向の回動が規制され、装置３０が耳にしっかりと装着される。これにより、装置３０が耳に対してグラつく不具合を防止することができ、検出部１を耳甲介腔２４に対して傾斜させることなく密着させることができ、生体情報の検出精度を向上させることができ、品質を向上させることができる。なお、この場合、仮に挿入部２が無くても、押圧部４’が耳甲介腔２４の下方の面にフィットし、且つ係合部６が対輪２５と耳甲介艇２６の間に押し込まれるため、装置３０を耳にしっかりとフィットさせて装着することができる。 However, the pressing portion 4'with the top portion 40 displaced downward fits the lower surface of the concha cavity 24, the insertion portion 2 is further inserted into the ear canal 21 at a predetermined depth, and the engaging portion 6 is paired. Since it is pushed between the wheel 25 and the ear canal boat 26, clockwise rotation is restricted and the device 30 is firmly attached to the ear. As a result, it is possible to prevent the device 30 from rattling with respect to the ear, and the detection unit 1 can be brought into close contact with the ear condyle cavity 24 without being tilted, thereby improving the detection accuracy of biological information. And can improve the quality. In this case, even if there is no insertion portion 2, the pressing portion 4'fits the lower surface of the concha cavity 24, and the engaging portion 6 is between the pair of wheels 25 and the concha boat 26. Since it is pushed in, the device 30 can be firmly fitted to the ear and worn.

以上のように、第２の実施形態によると、耳の大きさの違いをより広い範囲で許容することができ、サイズの異なるより多くの耳に装置３０をフィットさせることができ、耳の大きさに合わせてサイズの異なる装置３０を製造する必要がなくなる。よって、第２の実施形態の装置３０は、第１の実施形態の装置１０と比較して、製造コストを低減することができる。 As described above, according to the second embodiment, the difference in ear size can be tolerated in a wider range, the device 30 can be fitted to more ears of different sizes, and the ear size can be adjusted. It is no longer necessary to manufacture devices 30 having different sizes. Therefore, the apparatus 30 of the second embodiment can reduce the manufacturing cost as compared with the apparatus 10 of the first embodiment.

本発明は特許請求の範囲に記載された発明とその均等の範囲に含まれる。例えば、上述した第２の実施形態では、挿入部２、押圧部４’、係合部６、及び位置決め部８を備えた装置３０について説明したが、挿入部２や係合部６を備えていない場合であっても、一般的な大きさの耳に装置３０をフィットさせることができる。この場合、押圧部４’を耳珠裏と耳甲介腔２４の下側の部分に接触させて、装置のぐらつきを防止することができる。 The present invention is included in the invention described in the claims and the equivalent scope thereof. For example, in the second embodiment described above, the device 30 including the insertion portion 2, the pressing portion 4', the engagement portion 6, and the positioning portion 8 has been described, but the apparatus 30 includes the insertion portion 2 and the engagement portion 6. The device 30 can be fitted to a commonly sized ear, even if it is not present. In this case, the pressing portion 4'can be brought into contact with the back of the tragus and the lower portion of the tragus cavity 24 to prevent the device from wobbling.

また、上述した第２の実施形態では、耳甲介腔２４の中央に対し押圧部４’の頂部４０を下方にずらした場合について説明したが、耳の形によっては頂部４０を上方或いは前後にずらした方が装置３０を耳にフィットさせることができる場合がある。言い換えると、押圧部４’の頂部４０は、耳の形に合わせて配置すればよく、耳甲介腔２４の中央以外の部分に接触させることで効果を奏することができる。 Further, in the second embodiment described above, the case where the top 40 of the pressing portion 4'is moved downward with respect to the center of the concha cavity 24 has been described, but the top 40 is moved upward or back and forth depending on the shape of the ear. It may be possible to fit the device 30 to the ear by shifting it. In other words, the top 40 of the pressing portion 4'may be arranged according to the shape of the ear, and the effect can be achieved by contacting the portion other than the center of the concha cavity 24.
