Description

  The present invention relates to a technical field of a biological information detection apparatus that detects biological information such as blood flow rate and pulse rate.

  As this type of device, for example, a device that detects biological information in an outer ear portion of a living body is known. For example, in Patent Document 1, light is emitted from a light emitting element toward the outer ear portion of a living body, reflected light is detected by a light receiving element, and biological information such as a blood flow pulse wave is acquired based on the detection result. An apparatus is disclosed. This device is attached to the outer ear portion, for example, so as to sandwich the earlobe.

  On the other hand, ear-mounted earphones and the like are known as devices that are similarly attached to the outer ear and used. For example, Patent Document 2 discloses an apparatus that uses a cord connected to a speaker unit so as to be hung on an ear shell. In this device, since the cord to be hung on the ear shell can be adjusted to a length corresponding to the size of the user's ear shell, the device can be stably held in the outer ear portion.

Japanese Patent No. 4393568 JP 2011-151648 A

  However, with the technique described in Patent Document 2 described above, a situation can occur in which the length of the cord can be adjusted while the cord cannot be changed to a desired shape. Specifically, since the connection location and direction of the cord are fixed, even if the length of the cord can be adjusted, the bending angle and direction of the cord cannot be finely adjusted. Therefore, it cannot be said that an optimal shape for the user's ear shell can be reliably realized. Also, dedicated parts are used for the left and right ears, respectively, and the device used for one ear cannot be used for the other ear.

  Here, in the biological information detection apparatus as described in Patent Document 1 described above, it is desired that the biological information detection apparatus can be held extremely stably in the user's outer ear. It is also desired that the left and right ears can be used on the assumption that biological information cannot be detected properly with only one ear. However, the technique described in Patent Document 2 does not satisfy such conditions. Therefore, the technical problem that biometric information cannot be detected suitably may arise.

  The present invention has been made in view of the above-described problems, for example, and it is an object of the present invention to provide a biological information detection device that can be easily and stably attached and can detect biological information suitably. To do.

  In order to solve the above problems, the biological information detection apparatus of the present invention is connected to a detection unit that detects biological information, a member that holds the detection unit at a position where the biological information can be detected, and the detection unit. And a cable that can be bent along the ear shell of the living body, and the cable extends toward the upper portion of the ear shell in a state where the detection unit is held by the member.

  Hereinafter, embodiments of the present invention will be described.

  In order to solve the above-described problem, the biological information detection apparatus according to the present embodiment holds the detection unit that detects biological information included in the living body and the ear or the lobe of the living body so that the biological information is detected by the biological information. A clamping unit that holds the sensor in a detectable position; a cable that is connected to the detection unit and that can be bent along the ear shell of the living body; and is provided in the clamping unit, the angle of the cable being adjustable, and And a holding portion for holding the slide.

  The biological information detection apparatus according to the present embodiment includes a detection unit that detects biological information included in the biological information. The “biological information” here is a concept including a wide variety of information that can be detected from a living body, and examples thereof include information used in the medical field such as blood flow rate and pulse rate. It is done. The detection unit is configured as, for example, a probe unit having a light emitting element and a light receiving element (more specifically, for example, a laser blood flow meter using a laser Doppler flowmetry method), and emits light from the light emitting element to the subject. While irradiating, the light reflected by the subject is detected by the light receiving element. Information detected by the detection unit is transmitted to an external processing device or the like via a cable connected to the detection unit.

  When the biological information detection apparatus according to the present embodiment is actually used, the detection unit described above is held at a position where the biological information can be detected by holding the ear or the lobe of the living body by the holding unit. For example, the clamping unit is configured as a member having a shape like a clip, and the detection unit is arranged in an inner part of the clamping unit (that is, a part that contacts the ear or the lobe of a living body). If comprised in this way, when a biological ear or an earlobe is clamped by the clamping part, a detection part will be arrange | positioned so as to oppose the ear or earlobe of a biological body, and it becomes possible to detect biometric information suitably.

  Further, in a state where the above-described clamping unit clamps the living body ear or earlobe, the cable connected to the detection unit is bent so as to follow the living body ear shell. Thereby, the position of the detection part and the clamping part is more stably maintained compared with the case where the curved part of the cable is hooked on the ear shell of the living body and only the ear or the earlobe is clamped by the clamping part.

  Furthermore, in this embodiment, the holding part which hold | maintains a cable is provided in the clamping part, and a part of cable curved along the ear shell of a biological body is hold | maintained. According to such a configuration, the cable is bent along the ear shell between one end connected to the detection unit and a portion held by the holding unit provided in the holding unit. Note that the holding portion does not necessarily have to be provided on the holding member that holds the ear or the ear lobe in the holding portion, and may be provided on, for example, an extending member extending from the holding member or a connecting member connected to the holding member. That is, the holding part provided with the holding part is a concept that encompasses not only a holding member but also an integrated unit that includes the holding member.

  Here, in particular, according to the holding unit according to the present embodiment, the cable is held so as to be adjustable in angle and slidable. Here, “angle adjustable” means that the holding angle of the cable can be changed at least within a certain range. For example, the holding portion can be configured to be rotatable with respect to the holding portion. realizable. Alternatively, it can be realized by configuring the holding portion at least partially with an elastic body, or by disposing an elastic member inside the holding portion (specifically, a portion in contact with the cable). Further, “slidable” means a form that can be changed while maintaining the position where the cable is held. For example, the holding portion is configured by a ring-shaped member through which the cable is inserted. realizable.

  Since the holding angle of the cable can be adjusted by holding the cable so that the angle can be adjusted, it is possible to realize a cable shape that matches the shape of the ear shell of the living body. Further, it is possible to realize use with both the left and right ears. Further, by holding the cable in a slidable manner, the length of the curved portion can be changed without removing the cable from the holding portion. This makes it possible to realize a cable shape that more suitably matches the shape of the ear shell of the living body, as compared with the case where the angle can only be adjusted.

  As described above, according to the living body information detection apparatus of the present embodiment, easy and stable attachment to the living body is realized by adjusting the holding state of the cable in the holding unit. Therefore, it is possible to detect biometric information very suitably.

  In one aspect of the biological information detection apparatus according to the present embodiment, the holding unit holds the cable detachably.

  According to this aspect, the cable is detachably held by the holding portion (that is, in a state where the cable can be detached from the holding portion). Here, “removable” means not only a form in which the cable can be removed from the holding portion, but also the cable can be easily removed without any special work such as disassembly of the device. It means a form that can. Specifically, for example, the holding portion is provided with a slit, and the cable can be attached to and detached from the holding portion through the slit.

  Thus, if the cable can be attached to and detached from the holding portion, the device can be attached to and detached from the living body. Further, the holding state of the cable in the holding portion can be adjusted more suitably.

  In another aspect of the biological information detection apparatus according to the present embodiment, the holding unit is provided outside the clamping unit.

  According to this aspect, since the holding part is provided outside the holding part (that is, the side opposite to the side facing the ear or the earlobe of the living body), it is easy to recognize the position of the holding part from the outside of the apparatus and hold the holding part. It is easy to perform various operations on the part.

  Specifically, for example, the operation of attaching the cable to the holding portion when assembling the apparatus, the operation of removing the cable from the holding portion where the cable can be attached and detached, and the operation of attaching the cable in the opposite direction can be performed very easily.

  In another aspect of the biological information detection apparatus according to the present embodiment, the holding unit is provided inside the clamping unit.

  According to this aspect, since the holding part is provided inside the holding part (that is, the side facing the ear or the earlobe of the living body), it is possible to prevent the holding part from protruding outside the holding part. That is, the shape of the outer part of the device can be flattened.

  According to such a configuration, for example, the portion that touches the living body can be flattened, and therefore, it is possible to reduce discomfort and pain due to the protrusion of the component in the state of sleeping with the ear to which the device is attached. In addition, it is possible to prevent the cable from being accidentally detached from the holding portion to which the cable can be attached and detached due to contact with the outside.

  In another aspect of the biological information detection apparatus according to the present embodiment, the holding unit is provided so as to be detachable from the clamping unit.

  According to this aspect, the holding unit itself is configured to be removable from the clamping unit. For this reason, even when the cable is held in the holding portion, the same effect as that in which the cable is attached to and detached from the holding portion by removing the holding portion can be obtained. That is, it is possible to easily attach / detach the device to / from the living body, change left and right of the ear to be worn, or adjust the holding state of the cable. In addition, since the cable can be attached and detached while maintaining the cable holding state (for example, the cable slide position) with respect to the holding unit, it is possible to save the trouble of adjusting the holding state when the cable is reattached.

  In another aspect of the biological information detection apparatus according to the present embodiment, the holding unit includes a locking unit that locks the cable at a predetermined angle.

  According to this aspect, it is possible to fix the holding angle of the cable at a predetermined angle in the holding portion that holds the cable so that the angle can be adjusted. Thereby, it can prevent that the holding angle of a cable changes unintentionally, for example. In addition, it is possible to adjust the cable holding angle by setting in advance the frequently used locking position, such as the locking position when using the left ear and the locking position when using the right ear. It can be easily performed.

  In another aspect of the biological information detection device according to the present embodiment, the clamping unit includes a first member and a second member that are coupled to each other at a fulcrum, and each of the first member and the second member. Has a handle portion that is operated when the ear or the lobe is pinched, and one of the first member and the second member has the handle portion as viewed from the fulcrum. Shorter.

  According to this aspect, the clamping part is comprised as a member like a clip with which a 1st member and a 2nd member are mutually connected in a fulcrum. And especially each of the 1st member and the 2nd member has a handle part operated when pinching a living ear or an earlobe. For example, when a clamping operation is performed, an operation unit on the side opposite to the handle unit as viewed from the fulcrum is opened by operating the handle units of the first member and the second member to be pinched.

  Here, in this embodiment, in particular, one handle portion of the first member and the second member is configured to be shorter than the other handle portion when viewed from the fulcrum. That is, the length of the handle portion is configured to be different between the first member and the second member. If comprised in this way, the opening degree of an operation | movement part at the time of operating a handle part and opening an operation | movement part as mentioned above can be enlarged. That is, the limit value of the opening degree of the operating part determined by the position where the handle part of the first member and the handle part of the second member come into contact with each other is increased by making the lengths of the handle parts different from each other.

  In addition, if the dent is formed in the part of the longer handle part where the short handle part comes into contact, the distance until the handle parts come into contact with each other can be increased, so that the limit value of the opening of the operating part can be further increased. it can.

  When the opening limit of the operating portion is increased, not only can a thick object be sandwiched, but also beneficial effects can be obtained in operations other than the sandwiching operation. Specifically, it becomes possible to suitably execute a disinfection operation or the like performed before and after holding the ears or ear lobes of a living body.

  In another aspect of the biological information detection device according to the present embodiment, the clamping unit includes a first member and a second member that are coupled to each other at a fulcrum, and each of the first member and the second member. Each has a handle part that is operated when the ear or the earlobe is clamped, and an operation part that performs a clamping operation by operating the handle part, and is at least one member of the first member and the second member The height of the handle portion in the outer direction of the clamping portion is lower than that of the operating portion of the at least one member.

  According to this aspect, the clamping part is comprised as a member like a clip with which a 1st member and a 2nd member are mutually connected in a fulcrum. And especially each of the 1st member and the 2nd member has a handle part operated when pinching a living ear or an earlobe. Further, the side opposite to the handle portion as viewed from the fulcrum of the first member and the second member is an operation portion that performs a clamping operation by operating the handle portion.

  Here, in this embodiment, in particular, the handle portion of at least one member of the first member and the second member has a lower height in the outward direction of the sandwiching portion than the operation portion of at least one member ( That is, it is configured so that the protrusion to the outside of the apparatus is reduced. In such a configuration, the operating portion is more likely to come into contact with the outside by an amount that is higher than the handle portion. For this reason, it can prevent that a handle part contacts the exterior, for example, and an operation | movement part opens unintentionally. That is, it becomes possible to pinch a living ear or earlobe in a more stable state. Therefore, it is possible to prevent the device from being detached or the position of the detection unit from being shifted during detection of biological information.

  In another aspect of the biological information detection device according to the present embodiment, the clamping unit includes a detection unit holding member that holds the detection unit, and a surface on which the detection unit of the detection unit holding member is disposed. Recognizing means for recognizing the arrangement position of the detection unit from the back surface side is provided on the back surface.

  According to this aspect, the detection part which detects biometric information is hold | maintained at the detection part holding member contained in a clamping part. And especially the recognition means for recognizing the arrangement position of a detection part is provided in the back surface of the surface (namely, surface arrange | positioned facing a biological body) where the detection part of a detection part holding member is arrange | positioned. The recognizing means is provided as, for example, a mark or an unevenness indicating the arrangement position of the detection unit.

  By providing the recognition means, it is possible to easily recognize the arrangement position of the detection unit from the back surface (in other words, the outer surface of the apparatus) side of the surface on which the detection unit is arranged. Therefore, when the device is attached to the ear or earlobe of a living body, the detection unit can be held at an appropriate position without actually observing the detection unit.

  Such an operation and other gains in this embodiment will be further clarified from examples described below.

  Embodiments of the present invention will be described below with reference to the drawings.

<Overall configuration>
First, the overall configuration of the biological information detection apparatus according to the present embodiment will be described with reference to FIGS. FIG. 1 is an exploded view of the biological information detecting apparatus according to this embodiment. 2 and 3 are perspective views showing the overall configuration of the biological information detecting apparatus according to this embodiment.

  In FIG. 1, the biological information detection apparatus 100 according to the present embodiment includes a first clip 110, a second clip 120, a probe cover 130, a cushion 140, a shaft 150, a spring 160, a probe unit 170, a cable 180, and a cable clamp 190. It is prepared for.

  The first clip 110 and the second clip 120 are formed by molding a member such as POM (polyoxymethylene), so-called polyacetal resin, and function as a member for holding a living ear or earlobe when the device is used. To do.

  The probe cover 130 and the cushion 140 are formed by molding a resin such as silicon, and are attached to the first clip 110 and the second clip 120, respectively. The probe cover 130 and the cushion 140 are portions that actually contact the ears or ear lobes of the living body when the apparatus is used.

  The shaft 150 and the spring 160 are made by processing a metal such as SUS (Steel Use Stainless), for example, and have a function of connecting the first clip 110 and the second clip 120 to each other and applying a clamping force. .

  The probe unit 170 is configured to include a sensor or the like for detecting biological information that a living body has. A cable 180 is connected to the probe unit 170, and biological information detected by the probe unit 170 is output to the outside through the cable 180. Although illustration is omitted here, a connector is provided at an end of the cable 180 that is not connected to the probe unit 170, and is configured to be connectable to an external processing apparatus or the like.

  The cable clamp 190 is formed by molding a resin such as POM, and is configured to hold the cable 180 while being attached to the second clip 120. The cable clamp 190 is an example of the “holding portion” in the present invention. A specific configuration of the cable clamp 190 will be described in detail later.

  2 and 3, the biological information detection apparatus 100 according to the present embodiment is configured by assembling the above-described members as illustrated. In the following, for convenience of explanation, a portion operated during the clamping operation of the first clip 110 is a first handle portion 115, and a portion operated during a clamping operation of the second clip 120 is a second handle portion 125. Called. In addition, a portion that operates during the clamping operation including the first clip 110, the probe cover 130, and the probe unit 170 is a portion that operates during the clamping operation including the first operation unit 135, the second clip, and the cushion 140. This is referred to as a second operation unit 145. In addition, the member comprised by the 1st handle part 115 and the 1st action | operation part 135, and the member comprised by the 2nd handle part 125 and the 2nd action | operation part 145 are respectively "the 1st member" and "the 1st" of this invention. It is an example of “two members” and constitutes an example of the “clamping portion” of the present invention as a whole.

  In the biological information detection apparatus 100 according to the present embodiment, the probe unit 170 is housed inside the probe cover 130, but the sensor unit 175 for detecting biological information is provided from an opening provided in the probe cover 130. It arrange | positions so that it may expose (refer FIG. 3). The sensor unit 175 is an example of the “detection unit” of the present invention, and is configured as a laser blood flow meter using, for example, a laser Doppler flowmetry method, and detects a blood flow rate, a pulse rate, and the like of a living body.

  In the sensor holding unit 250 of the first operating unit 135 (that is, the member holding the sensor unit 175), the exact position of the sensor unit 175 is located from the outside of the apparatus at a position just behind the sensor unit 175. A sensor mark 200 that facilitates recognition is provided (see FIG. 2). The sensor mark 200 is formed by, for example, engraving or printing. Note that the position of the sensor mark 200 is preferably the position just behind the sensor unit 175 as shown in the figure. However, if the position of the sensor unit 175 can be sufficiently recognized, the sensor mark 200 is slightly shifted. It may be arranged at a position.

<Installation method>
Next, a mounting method of the biological information detection apparatus according to the present embodiment will be described with reference to FIGS. FIG. 4 is a front view (No. 1) showing an example of wearing the biological information detecting apparatus according to the present embodiment. FIG. 5 is a side view showing a mounting example of the biological information detection apparatus according to the present embodiment.

  4 and 5, the biological information detection apparatus 100 according to the present embodiment is used by being worn on, for example, a living ear or earlobe. Specifically, as shown in the drawing, the earlobe of the left ear 510 of the living body is sandwiched between the first operation unit 135 and the second operation unit 145. If it does in this way, sensor part 175 arranged inside the 1st operation part 135 will be arranged so as to oppose an earlobe, and it will become possible to detect living body information suitably. In addition, as long as it is a position which can detect biometric information, you may wear | wear so that parts (for example, an ear ring etc.) other than an earlobe may be clamped.

  As can be seen from FIG. 4, when the device is attached to the earlobe of a living body, the cable 180 connected to the probe unit 170 is bent along the earshell and hooked on the earshell. Installed as follows. More specifically, the cable extending from the tip of the probe unit 170 is drawn from the upper side of the right ear 510 to the lower side through the back of the ear ring, and is held by the cable clamp 190 around the ear lobe of the right ear 510. The cable clamp 190 is provided with a slit (gap) for attaching and detaching the cable 180, so that the cable can be easily attached and detached.

  As described above, if the cable 180 is used so as to be hung on the ear shell, the wearing state of the apparatus is more stable as compared with the case where the ear lobe is simply held between the first operation unit 135 and the second operation unit 145. can do. The shape of the cable 180 can be appropriately adjusted according to the shape of the ear of the living body. That is, even when the shape of the ear of the living body is different, it can be adjusted to a shape that surely fits the ear. A detailed adjustment method will be described below.

<Cable adjustment method>
Next, a cable adjustment method using the above-described cable clamp will be described in detail with reference to FIGS. FIG. 6 is a conceptual diagram showing the adjustment function of the cable holding state in the cable clamp. FIG. 7 is a front view (No. 2) showing an example of wearing the biological information detecting apparatus according to the present embodiment. 8 and 9 are partially enlarged views showing the locking mechanism of the cable clamp.

  In FIG. 6, the cable clamp 190 according to the present embodiment holds the cable 180 so as to be slidable. Specifically, the cable clamp 190 is configured not to hold the cable 180 so as to be completely fixed, but to change the holding position in the held state. Accordingly, the length of the curved portion of the cable 180 (that is, the portion related to the ear) can be freely adjusted, and the cable 180 can be fitted to the ear of the living body.

  The cable clamp 190 according to the present embodiment holds the cable 180 so that the angle can be adjusted. Specifically, the cable clamp 190 is rotatable on the attached second handle portion 125. For this reason, the holding angle of the cable 180 can be freely changed. Therefore, compared with the case where the holding angle of the cable 180 is fixed, it is possible to make the shape of the cable 180 more fit to the ear of the living body.

  Further, as shown in FIG. 7, the holding angle of the cable 180 of the device used in the left ear 510 can be changed and used in the right ear 520. For this reason, for example, when one ear is not suitable for detecting biological information or when detecting biological information from both ears, the biological information can be detected by one device.

  Incidentally, since the cable clamp 190 is provided with a slit for attaching and detaching the cable 180, even if the adjustment is difficult while holding the cable 180, the adjustment can be performed by removing the cable. . Further, since the cable clamp 190 itself can be attached / detached from the second handle portion 125, the cable clamp 190 can be detached and adjusted while holding the cable 180. In this case, since the holding position of the cable is maintained, it is very convenient when the left and right ears are used interchangeably, for example. Furthermore, the cable clamp 190 may be provided with a mechanism for locking the holding angle of the cable 180 as described below.

  In FIG. 8, the cable clamp 190 according to the present embodiment is provided with a protrusion 195. The protrusion 195 has a shape that matches the left ear recess 310 and the right ear recess 320 provided in the second handle portion 125, and can be locked at a rotation angle at a predetermined position. According to such a structure, it can prevent that the holding angle of the cable 180 after adjustment changes unintentionally. In addition, if it is locked at the position of the left ear recess 310, an angle suitable for detection by the left ear 510 is obtained, and if it is locked at the position of the right ear recess 320, an angle suitable for detection by the right ear 520 is obtained. Therefore, the angle adjustment of the cable 180 can be performed very easily.

  In FIG. 9, the locking mechanism described above may not be locked at a preset angle, but may be such that the angle is appropriately fixed. For example, if a bellows locking mechanism 195a as shown in the figure is used, a very large number of locking angles can be realized as compared with the example of FIG. . In the drawing, for convenience of explanation, the bellows portion is illustrated as having a relatively large unevenness, but by making the bellows finer, a very fine angle adjustment is possible.

<Detailed configuration>
Next, a detailed configuration unique to the biological information detection apparatus according to the present embodiment will be described with reference to FIGS. FIG. 10 is a side view showing the difference in length between the first handle portion and the second handle portion. FIG. 11 is a side view showing a state in which the first operation unit and the second operation unit are fully opened. Further, FIG. 12 is a side view showing a difference in height between the first handle portion and the sensor holding portion.

  10, in the biological information detection apparatus 100 according to the present embodiment, the length L1 from the fulcrum (that is, the shaft 150) of the first handle portion 115 is longer than the length L2 from the fulcrum of the second handle portion 125. It is configured to be shorter.

  In FIG. 11, the first operation unit 135 and the second operation when performing the clamping operation by making a difference between the length L1 of the first handle portion 115 and the length L2 of the second handle portion 125 as described above. The opening degree of the part 145 can be increased. Specifically, in a region A surrounded by a broken line in the drawing, the first handle portion 115 and the second handle portion 125 are in a state where they are difficult to contact each other. For this reason, it becomes possible to operate the 1st handle part 115 and the 2nd handle part 125 in a wider range, and as a result, the 1st operation part 135 and the 2nd operation part 145 will open greatly.

  Incidentally, from the viewpoint of making it difficult for the first handle portion 115 and the second handle portion 125 to contact each other, for example, the same effect can be obtained by providing a dent in the portion of the second handle portion 125 that contacts the first handle portion 115. Is obtained. Therefore, if it uses in addition to the structure which makes a difference in the length of the said handle part, the opening degree of the 1st action | operation part 135 and the 2nd action | operation part 145 can be enlarged further.

  When the first operation unit 135 and the second operation unit 145 are increased, not only a thicker one can be sandwiched, but also the visibility of the inside of the first operation unit 135 and the second operation unit 145 and the ease of work are improved. improves. For this reason, for example, very useful effects such as easy disinfection before and after use can be obtained.

  Here, the example in which the length L1 of the first handle portion 115 is shorter than the length L2 of the second handle portion 125 has been described, but conversely, the length L1 of the first handle portion 115 is longer. The same effect can be obtained even when the length L2 of the second handle portion 125 is longer.

  In FIG. 12, the biological information detection apparatus 100 according to the present embodiment is further configured so that the height h1 of the first handle portion 115 toward the device outer side direction (that is, the downward direction in the drawing) is the sensor in the first operation unit 135. The sensor holding member 400 that holds the portion 175 is configured to be lower than the height h <b> 2 toward the apparatus outer side direction. According to this configuration, for example, when the user is sleeping on the bed 600 so that the ear wearing the apparatus is on the lower side, the sensor holding member 400 higher than the first handle portion 115 contacts the bed 600 ( (See region B in the figure). On the other hand, the 1st handle part 115 whose height is lower than a sensor holding member does not contact the bed 600 (refer area C in the figure). As described above, since the pressure from the outside of the apparatus is first applied to the first operation portion 135, the living body ear 510 is more securely held by the first operation unit 135 and the second operation unit 145. . In addition, it is possible to prevent the device from being detached or the mounting position from being shifted due to the first handle portion 115 being erroneously operated.

<Modification>
Next, a modification of the biological information detection apparatus according to the present embodiment will be described with reference to FIGS.

  First, a modification in which the arrangement position of the cable clamp 190 is different will be described with reference to FIG. FIG. 13 is a side view showing a modified example of the biological information detecting apparatus according to the present embodiment.

  In FIG. 13, the cable clamp 190 according to the modification is attached not to the outer portion of the second handle portion 125 but to the inner portion. If comprised in this way, since it can prevent that the cable clamp 190 protrudes outside the 2nd handle part 125, the shape of the outer part of an apparatus can be planarized. In this case, for example, the portion that touches the living body can be flattened, so that it is possible to reduce discomfort and pain due to the protrusion of the component in the state where the ear is worn with the device down. Further, it is possible to prevent the cable 180 from being accidentally detached from the cable clamp 190 due to contact with the outside or the like.

  Next, modified examples in which the shape of the cable clamp 190 is different will be described with reference to FIGS. 14 to 18. 14 and 15 are perspective views showing modifications of the biological information detecting apparatus according to the present embodiment. Moreover, FIG. 16 is sectional drawing which shows the modification of the biometric information detection apparatus based on a present Example. 17 and 18 are cross-sectional views taken along line AA of FIG.

  In FIG. 14, the cable clamp 190 a is attached to the tip of the second handle portion 125 and is configured to be rotatable about the rotation shaft 191. The cable clamp 190a is configured to hold the cable 180 in a slidable manner, similarly to the cable clamp 190 shown in FIG.

  The cable clamp 190a is rotated about the rotation shaft 191 to change the relative angle with respect to the second handle portion 125. For this reason, the holding angle of the cable 180 can be adjusted by rotating the cable clamp 190a.

  If the cable clamp 190a is formed of a flexible elastic body or the like, the holding angle of the cable 180 can be adjusted by curving the cable clamp 190a itself. That is, the holding angle of the cable 180 can be adjusted without rotating the cable clamp 190a.

  In FIG. 15, the cable clamp 190 b is provided on the second handle portion 125 and has an opening 192. As shown in the figure, the opening 192 is configured to allow the cable 180 to be inserted therethrough.

  As shown in FIG. 16, in the cable clamp 190b, the cable 180 is held by being inserted into the opening 192. The cable 180 is held by friction inside the opening 192. The cable 180 is not completely fixed inside the opening 192 but is slidably held.

  Note that a part of the cable clamp 190b may be formed of an elastic member. Further, at least a part of the opening is designed to be smaller than the cable diameter, and may be held by press-fitting.

  As shown in FIGS. 17 and 18, the opening 192 of the cable clamp 190b is configured such that the inlet portion and the outlet portion are wide and the central portion is narrow. If it does in this way, the direction of the cable 180 in an entrance part and an exit part can be adjusted. For this reason, the holding angle of the cable 180 can be adjusted.

  As described above, according to the biological information detection apparatus 100 according to the present embodiment, easy and stable attachment to a living body is realized by adjusting the holding state of the cable 180 in the cable clamp 190. Therefore, it is possible to detect biometric information very suitably.

  In the above-described example, only the example in which the biological information detecting device 100 according to the present embodiment is used by being worn on the ear or earlobe of a living body has been described, but by changing some configurations such as a clip portion, For example, it can be used by being attached to another part such as a fingertip. Even in such a case, the adjustment function by the cable clamp 190 described above has a beneficial effect.

  The present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the gist or concept of the invention that can be read from the claims and the entire specification. Is also included in the technical scope of the present invention.
