Description

The present invention relates to the technical field of a biological information detection device that detects biological information such as blood flow and pulse rate, for example.

As a device of this type, for example, a device that detects biological information in the outer ear of a living body is known. For example, in Patent Document 1, light is emitted from a light emitting element toward the outer ear of a living body, the 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. The device is disclosed. This device is attached to the outer ear portion, for example, by sandwiching the earlobe.

On the other hand, as a device that is similarly attached to the outer ear portion and used, an ear-hook type earphone or the like is known. For example, Patent Document 2 discloses a device that uses a cord connected to a speaker unit so as to hang it on the auricle. In this device, the cord hung on the auricle can be adjusted to a length corresponding to the size of the user's auricle, so that the device can be stably held in the outer ear portion.

Japanese Patent No. 4393568 Japanese Unexamined Patent Publication No. 2011-151648

However, in the technique described in Patent Document 2 described above, while the length of the cord can be adjusted, a situation may occur in which the cord cannot be changed into 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 the optimum shape for the user's auricle can be surely realized. In addition, dedicated parts are used for each of the left and right ears, and the device used for one ear cannot be used for the other ear.

Here, it is desired that the biometric information detection device as described in Patent Document 1 described above can be held extremely stably in the outer ear of the user due to its nature. It is also desired that the biometric information can be used in both the left and right ears, assuming that the biometric information cannot be appropriately detected by only one ear. However, the technique described in Patent Document 2 does not satisfy such a condition. Therefore, there may be a technical problem that biometric information cannot be suitably detected.

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

In order to solve the above problems, the biometric information detection device of the present invention is connected to a detection unit that detects biometric information, a member that holds the detection unit at a position where the biometric information can be detected, and the detection unit. The cable comprises a cable that is bendable along the auricle of the living body, and the cable extends upward of the auricle while the detection unit is held by the member.

Hereinafter, embodiments of the present invention will be described.

In order to solve the above-mentioned problem, the biological information detection device according to the present embodiment sandwiches the biological information of the living body with the detection unit for detecting the biological information of the living body, so that the biological information can be obtained by sandwiching the detection unit with the ear or earlobe of the living body. A holding portion that is held in a detectable position, a cable that is connected to the detection portion and can be curved along the auricle of the living body, and a cable that is provided in the holding portion so that the angle of the cable can be adjusted and It is provided with a holding portion that holds it in a slidable manner.

The biometric information detection device according to the present embodiment is provided with a detection unit for detecting the biometric information contained in the biometric information. The "biological information" here is a concept including a wide variety of information that can be detected from the living body, and examples thereof include information used in the medical field such as blood flow and pulse rate. Be 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 a subject. Along with irradiating, the light reflected by the subject is detected by the light receiving element. The information detected in the detection unit is transmitted to an external processing device or the like via a cable connected to the detection unit.

When the biometric information detection device according to the present embodiment is actually used, the above-mentioned detection unit is held at a position where biometric information can be detected by pinching the ear or earlobe of the living body by the pinching portion. For example, the pinching portion is configured as a member shaped like a clip, and the detecting portion is arranged in an inner portion of the pinching portion (that is, a portion in contact with the ear or earlobe of a living body). With this configuration, when the ear or earlobe of a living body is sandwiched between the holding parts, the detection unit is arranged so as to face the ear or earlobe of the living body, and it is possible to suitably detect biological information.

Further, in a state where the above-mentioned holding portion holds the ear or earlobe of the living body, the cable connected to the detecting portion is curved along the ear shell of the living body. As a result, the positions of the detection unit and the pinching portion are more stably maintained as compared with the case where the curved portion of the cable is hooked on the auricle of the living body and the ear or the earlobe is simply pinched by the pinching portion.

Further, in the present embodiment, the holding portion is provided with a holding portion for holding the cable, and a part of the cable curved along the auricle of the living body is held. According to such a configuration, the cable is curved along the auricle between one end connected to the detection portion and the portion held by the holding portion provided in the holding portion. The holding portion does not necessarily have to be provided on the holding member that sandwiches the ear or the earlobe in the holding portion, and may be provided on, for example, an extension member extending from the holding member or a connecting member connected to the holding member. That is, the holding portion provided with the holding portion is a concept that includes not only the holding member but also an integrated unit including the holding member.

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

By holding the cable so that the angle can be adjusted, the holding angle of the cable can be adjusted, so that it is possible to realize a cable shape that matches the shape of the auricle of the living body. Furthermore, it is possible to realize the use with both the left and right ears. Further, by holding the cable slidably, it is possible to change the length of the curved portion without removing the cable from the holding portion. This makes it possible to more preferably realize a cable shape that matches the shape of the auricle of a living body, as compared with the case where the angle can only be adjusted.

As described above, according to the biological information detection device 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 portion. Therefore, it is possible to detect biological information extremely suitably.

In one aspect of the biometric information detection device according to the present embodiment, the holding portion holds the cable detachably.

According to this aspect, the cable is held detachably (that is, detachable from the holding portion) by the holding portion. The term "detachable" here means not only that the cable can be removed from the holding portion, but also that the cable can be easily removed without any special work such as disassembling the device. It means the form that can be done. Specifically, for example, a slit is provided in the holding portion, and the cable can be attached to and detached from the holding portion via the slit.

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

In another aspect of the biological information detection device according to the present embodiment, the holding portion is provided on the outside of the holding portion.

According to this aspect, since the holding portion is provided on the outside of the holding portion (that is, the side opposite to the side facing the ear or earlobe of the living body), the position of the holding portion can be easily recognized from the outside of the device and the holding portion is held. It is easy to perform various work on the part.

Specifically, for example, the work of attaching the cable to the holding portion at the time of assembling the device, the work of removing the cable from the holding portion to which the cable can be attached and detached, and the work of attaching the cable in the opposite direction can be performed extremely easily.

In another aspect of the biological information detection device according to the present embodiment, the holding portion is provided inside the holding portion.

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

According to such a configuration, for example, since the portion that comes into contact with the living body can be flattened, it is possible to reduce discomfort and pain due to the protrusion of the component while lying down with the ear on 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 or the like.

In another aspect of the biological information detection device according to the present embodiment, the holding portion is provided so as to be removable from the holding portion.

According to this aspect, the holding portion itself is configured to be removable from the holding portion. Therefore, even if the cable is still held in the holding portion, the same effect as that of attaching / detaching the cable to / from the holding portion can be obtained by attaching / detaching the holding portion. That is, the device can be easily attached to and detached from the living body, the left and right ears to be worn can be exchanged, and the holding state of the cable can be easily adjusted. Further, since the cable can be attached / detached while maintaining the holding state of the cable with respect to the holding portion (for example, the slide position of the cable), it is possible to save the trouble of adjusting the holding state when the cable is reattached.

In another aspect of the biometric information detecting device according to the present embodiment, the holding portion has a locking means for locking 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. This makes it possible to prevent, for example, the holding angle of the cable from being unintentionally changed. In addition, the cable holding angle can be adjusted by presetting frequently used locking positions such as the locking position when used for the left ear and the locking position when used for the right ear. It can be easily done.

In another aspect of the biological information detection device according to the present embodiment, the sandwiching portion is configured to include a first member and a second member connected to each other at a fulcrum, and each of the first member and the second member. Has a handle portion to be operated when sandwiching the ear or earlobe, and the handle portion of one of the first member and the second member is the other handle portion when viewed from the fulcrum. Shorter.

According to this aspect, the sandwiching portion is configured as a clip-like member in which the first member and the second member are connected to each other at a fulcrum. In particular, each of the first member and the second member has a handle portion to be operated when holding the ear or earlobe of a living body. For example, in the case of performing the pinching operation, by operating the handle portions of the first member and the second member so as to be pinched, the operating portion on the opposite side of the handle portion when viewed from the fulcrum is opened.

Here, in this embodiment, in particular, the handle portion of one 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. With this configuration, it is possible to increase the opening degree of the operating portion when the handle portion is operated to open the operating portion as described above. That is, the limit value of the opening degree of the operating portion determined by the position where the handle portion of the first member and the handle portion of the second member come into contact with each other is increased by making the lengths of the handle portions different from each other.

If a dent is formed in the portion of the longer handle where the short handle contacts, the distance until the handles come into contact with each other can be increased, so that the limit value of the opening of the moving portion can be further increased. can.

When the opening limit of the moving portion is increased, not only a thick object can be pinched, but also a beneficial effect can be obtained in an operation other than the pinching operation. Specifically, it is possible to suitably perform disinfection work and the like performed before and after sandwiching the ear or earlobe of a living body.

In another aspect of the biological information detection device according to the present embodiment, the sandwiching portion is configured to include a first member and a second member connected to each other at a fulcrum, and each of the first member and the second member. Each has a handle portion operated when the ear or earlobe is pinched, and an operating portion that performs a pinching operation by operating the handle portion, and at least one member of the first member and the second member. The handle portion in the above is lower in height toward the outside of the holding portion than the moving portion of the at least one member.

According to this aspect, the sandwiching portion is configured as a clip-like member in which the first member and the second member are connected to each other at a fulcrum. In particular, each of the first member and the second member has a handle portion to be operated when holding the ear or earlobe of a living body. Further, the side opposite to the handle portion when viewed from the fulcrum of the first member and the second member is an operation portion that performs a pinching operation by operating the handle portion.

Here, in this embodiment, in particular, the handle portion of at least one of the first member and the second member has a lower height toward the outside of the sandwiching portion than the operating portion of at least one member ( That is, it is configured so that the protrusion to the outside of the device is small). In such a configuration, the moving portion is in a state where it is easier to come into contact with the outside because the height is higher than that of the handle portion. Therefore, for example, it is possible to prevent the handle portion from coming into contact with the outside and unintentionally opening the moving portion. That is, it becomes possible to hold the ear or earlobe of a living body in a more stable state. Therefore, it is possible to prevent the device from coming off or the position of the detection unit from being displaced during the detection of biological information.

In another aspect of the biological information detection device according to the present embodiment, the sandwiching portion is configured to include 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 arranged. On the back surface of the above, a recognition means for recognizing the arrangement position of the detection unit from the back surface side is provided.

According to this aspect, the detection unit for detecting biological information is held by the detection unit holding member included in the sandwiching unit. In particular, a recognition means for recognizing the arrangement position of the detection unit is provided on the back surface of the surface on which the detection unit of the detection unit holding member is arranged (that is, the surface facing the living body). The recognition means is provided, for example, as a mark indicating the arrangement position of the detection unit, unevenness, or the like.

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 device) 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 visually observing the detection unit.

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

Hereinafter, examples of the present invention will be described with reference to the drawings.

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

In FIG. 1, the biological information detection device 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 configured in preparation.

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

The probe cover 130 and the cushion 140 are made 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 come into contact with the ear or earlobe of a living body when the device is used.

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

The probe unit 170 is configured to include a sensor or the like for detecting biological information possessed by the living body. A cable 180 is connected to the probe unit 170, and biometric information detected by the probe unit 170 is output to the outside via the cable 180. Although not shown here, a connector is provided at the end of the cable 180 that is not connected to the probe unit 170, so that the cable 180 can be connected to an external processing device or the like.

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

In FIGS. 2 and 3, the biological information detection device 100 according to the present embodiment is configured by assembling the above-mentioned members as shown in the figure. In the following, for convenience of explanation, the portion operated during the pinching operation of the first clip 110 is the first handle portion 115, and the portion operated during the pinching operation of the second clip 120 is the second handle portion 125. It is called. Further, the portion that operates during the pinching operation including the first clip 110, the probe cover 130, and the probe unit 170 is the portion that operates during the pinching operation including the first operating portion 135, the second clip, and the cushion 140. It is referred to as a second moving unit 145. The members composed of the first handle portion 115 and the first moving portion 135, and the members composed of the second handle portion 125 and the second moving portion 145 are the "first member" and the "first member" of the present invention, respectively. It is an example of "two members", and constitutes an example of the "pinching portion" of the present invention as a whole.

In the biological information detection device 100 according to the present embodiment, the probe unit 170 is housed inside the probe cover 130, but the sensor unit 175 for detecting the biological information is from the opening provided in the probe cover 130. It is arranged so as to be exposed (see FIG. 3). This 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 flow cytometry method, and detects a blood flow volume, a pulse rate, etc. of a living body.

In addition, in the sensor holding part 250 (that is, the member holding the sensor part 175) of the first operating part 135, the exact position of the sensor part 175 is placed at the position just behind the sensor part 175 from the outside of the device. A sensor mark 200 is provided for easy recognition (see FIG. 2). The sensor mark 200 is formed by, for example, engraving or printing. As shown in the figure, the position of the sensor mark 200 is preferably a position just behind the sensor unit 175, but if the position of the sensor unit 175 can be sufficiently recognized, it is slightly displaced. It may be placed in a position.

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

In FIGS. 4 and 5, the biological information detection device 100 according to the present embodiment is used by being attached to, for example, the ear or earlobe of a living body. Specifically, as shown in the figure, the earlobe of the left ear 510 of the living body is sandwiched between the first moving portion 135 and the second moving portion 145. By doing so, the sensor unit 175 arranged inside the first moving unit 135 is arranged so as to face the earlobe, and biometric information can be suitably detected. In addition, as long as it is a position where biometric information can be detected, it may be worn so as to sandwich a part other than the earlobe (for example, an ear ring).

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 curved along the auricle and hangs on the auricle. It is installed like this. 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 helix and is held by the cable clamp 190 around the earlobe of the right ear 510. The cable clamp 190 is provided with a slit (gap) for attaching / detaching the cable 180, so that the cable can be easily attached / detached.

As described above, when the cable 180 is used so as to hang it on the auricle, the wearing state of the device becomes more stable as compared with the case where the earlobe is simply sandwiched between the first moving portion 135 and the second moving portion 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 if the shape of the ear of the living body is different, the shape can be adjusted so as to surely fit the ear. The detailed adjustment method will be described below.

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

In FIG. 6, the cable clamp 190 according to the present embodiment slides the cable 180. Specifically, the cable clamp 190 is configured so that the cable 180 is not held so as to be completely fixed, but the holding position can be changed while the cable 180 is held. As a result, the length of the curved portion (that is, the portion related to the ear) of the cable 180 can be freely adjusted, and the cable 180 can be fitted to the ear of the living body.

Further, the cable clamp 190 according to this embodiment holds the cable 180 so that the angle can be adjusted. Specifically, the cable clamp 190 is capable of rotating itself on the attached second handle portion 125. Therefore, the holding angle of the cable 180 can be freely changed. Therefore, the shape of the cable 180 can be made to fit the ears of the living body better than the case where the holding angle of the cable 180 is fixed.

Further, as shown in FIG. 7, it is also possible to change the holding angle of the cable 180 of the device used in the left ear 510 and use it in the right ear 520. Therefore, for example, even when one ear is not suitable for detecting the biological information, or when the biological information is detected from both ears, the biological information can be detected by one device.

By the way, since the cable clamp 190 is provided with a slit for attaching / detaching the cable 180, even if the adjustment is difficult while holding the cable 180, the adjustment can be made by removing the cable. .. Further, since the cable clamp 190 itself can be attached to and detached from the second handle portion 125, the cable clamp 190 can be removed and adjusted while holding the cable 180. In this case, since the holding position of the cable is maintained, it is very convenient when, for example, the left and right ears are exchanged for use. Further, 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 this 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 125, and the rotation angle can be locked at a predetermined position. According to such a configuration, it is possible to prevent the holding angle of the cable 180 after adjustment from being unintentionally changed. Further, if it is locked at the position of the recess for the left ear 310, the angle is suitable for detection at the left ear 510, and if it is locked at the position of the recess 320 for the right ear, the angle is suitable for detection at the right ear 520. Therefore, the angle of the cable 180 can be adjusted extremely easily.

In FIG. 9, the locking mechanism described above may not be locked at a preset angle, but may be appropriately fixed at an angle. For example, if the 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. 8, so that the shape of the cable 180 that fits the ear of a living body can be suitably realized. .. In the figure, for convenience of explanation, the bellows portion is shown to have relatively large irregularities, but by making the bellows finer, extremely fine angle adjustment is possible.

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

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

In FIG. 11, 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 first operation portion 135 and the second operation when performing the pinching operation are performed. The opening degree of the portion 145 can be increased. Specifically, in the region A surrounded by the broken line in the figure, the first handle portion 115 and the second handle portion 125 are in a state where it is difficult for them to come into contact with each other. Therefore, the first handle portion 115 and the second handle portion 125 can be operated in a wider range, and as a result, the first moving portion 135 and the second moving portion 145 are greatly opened.

Incidentally, from the viewpoint of making it difficult for the first handle portion 115 and the second handle portion 125 to come into contact with each other, for example, providing a dent in the portion of the second handle portion 125 that comes into contact with the first handle portion 115 has the same effect. Is obtained. Therefore, if it is used in addition to the configuration of making a difference in the length of the handle portion, the opening degree of the first moving portion 135 and the second moving portion 145 can be further increased.

When the first moving unit 135 and the second moving unit 145 become larger, not only a thicker object can be sandwiched, but also the visibility and workability of the inside of the first moving unit 135 and the second moving unit 145 become easier. improves. Therefore, for example, a very beneficial effect such as easy disinfection work before and after use can be obtained.

Here, an 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 smaller. Even when the length L2 of the second handle portion 125 is longer than that, the same effect can be obtained.

In FIG. 12, the biological information detection device 100 according to the present embodiment further has a height h1 of the first handle portion 115 toward the outside of the device (that is, the lower direction in the figure) of the sensor in the first operating portion 135. The height of the sensor holding member 400 that holds the portion 175 toward the outside of the device is lower than h2. With this configuration, for example, when the ear on which the device is attached is lying on the bed 600 so as to be on the lower side, the sensor holding member 400 higher than the first handle portion 115 comes into contact with the bed 600 ( See area B in the figure). On the other hand, the first handle portion 115, which is lower in height than the sensor holding member, does not come into contact with the bed 600 (see region C in the figure). In this way, since the pressure from the outside of the device is first applied to the first moving portion 135, the first moving portion 135 and the second moving portion 145 more reliably pinch the ear 510 of the living body. .. Further, it is possible to prevent the device from being disengaged or the mounting position from being displaced due to the accidental operation of the first handle portion 115.

<Modification example>
Next, a modified example of the biological information detection device according to this embodiment will be described with reference to FIGS. 13 to 18.

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

In FIG. 13, the cable clamp 190 according to the modified example is attached to the inner portion of the second handle portion 125, not the outer portion. With this configuration, it is possible to prevent the cable clamp 190 from protruding to the outside of the second handle portion 125, so that the shape of the outer portion of the device can be flattened. In this case, for example, since the portion that comes into contact with the living body can be flattened, it is possible to reduce the discomfort and pain caused by the protrusion of the parts while lying down with the ear on which the device is attached. 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.

Subsequently, a modified example 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 a modified example of the biological information detection device according to the present embodiment, respectively. Further, FIG. 16 is a cross-sectional view showing a modified example of the biological information detection device according to the present embodiment. Further, FIGS. 17 and 18 are sectional views taken along the line AA of FIG. 16, respectively.

In FIG. 14, the cable clamp 190a 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 slidably hold the cable 180, similar to the cable clamp 190 shown in FIG. 6 and the like.

By rotating the cable clamp 190a around the rotation shaft 191, the relative angle with respect to the second handle portion 125 changes. Therefore, the holding angle of the cable 180 can be adjusted by rotating the cable clamp 190a.

Further, if the cable clamp 190a is made of a flexible elastic body or the like, the holding angle of the cable 180 can be adjusted by bending 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 190b is provided on the second handle portion 125 and has an opening portion 192. As shown in the figure, the opening 192 is configured so that the cable 180 can 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 within the opening 192. The cable 180 is not completely fixed inside the opening 192, but is held slidably.

The cable clamp 190b may be partially made of an elastic member. Further, at least a part of the opening may be 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. In this way, the direction of the cable 180 at the inlet portion and the outlet portion can be adjusted. Therefore, it is possible to adjust the holding angle of the cable 180.

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

In the above-mentioned example, only the example in which the biological information detection device 100 according to the present embodiment is used by being attached to the ear or earlobe of the living body has been described, but by changing a part of the configuration such as the clip portion, the configuration may be changed. For example, it can be used by attaching it 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 embodiment, and can be appropriately changed within the scope of the claims and within the range not contrary to the gist or idea of the invention that can be read from the entire specification, and the biological information detection device accompanied by such changes. Is also included in the technical scope of the present invention.
