FIG. 1 is a schematic view showing the appearance of the measuring device according to the embodiment. In the present embodiment, the measuring device 100 includes a mounting unit 110, a first measuring unit 120a and a second measuring unit 120b, and a first connecting unit 130a and a second connecting unit 130b. The measuring device 100 measures information on the blood flow of the subject while being attached to the subject. The measuring device 100 may be attached to the head of the subject, for example. In the present embodiment, the measuring device 100 will be described below assuming that the measuring device 100 is used while being attached to the head of the subject.

The mounting unit 110 is a mechanism for maintaining the mounting state of the measuring device 100 with respect to the subject. In the present embodiment, the mounting portion 110 has an arch shape, for example, as shown in FIG. The subject can mount the measuring device 100 by sandwiching the head between the mounting portions 110. The mounting portion 110 may have, for example, a mechanism whose length can be adjusted according to the size of the head of the subject. The mounting portion 110 is made of, for example, plastic or the like.

The first measuring unit 120a and the second measuring unit 120b are connected to the mounting unit 110 at the first end 110a and the second end 110b of the mounting unit 110 via the first connecting unit 130a and the second connecting unit 130b, respectively. To. That is, the mounting unit 110, the first measuring unit 120a and the second measuring unit 120b, and the first connecting unit 130a and the second connecting unit 130b are configured as one earphone type measuring device 100 connected as a whole. ing. The first connecting portion 130a is formed at a portion that connects the first measuring portion 120a and the first end 110a of the mounting portion 110. The second connecting portion 130b is formed at a portion that connects the second measuring portion 120b and the second end 110b of the mounting portion 110.

The first measurement unit 120a and the second measurement unit 120b measure information regarding the blood flow of the subject. The functions of the first measuring unit 120a and the second measuring unit 120b are the same. In the present specification, when the first measuring unit 120a and the second measuring unit 120b are not distinguished, they are collectively referred to as the measuring unit 120.

In this embodiment, the measuring unit 120 measures information about blood flow in the ear of the subject. The measuring unit 120 measures information on blood flow, for example, in the ear canal of a subject.

The first measuring unit 120a measures information on blood flow, for example, in the concha of the right ear of the subject. The first measuring unit 120a includes a main body 121a, an earpiece 122a, and a sensor unit 123a. The earpiece 122a is inserted into the ear canal of the right ear of the subject while the measuring device 100 is worn. The earpiece 122a is made of, for example, silicon or the like. The sensor unit 123a is provided at a position in the main body 121a where the earpiece 122a is inserted into the ear canal of the right ear and comes into contact with the concha of the right ear, which is the test site. The main body 121a also functions as a case for protecting the measurement mechanism (details will be described later) included in the sensor unit 123a. The main body 121a is made of, for example, plastic or the like. The earpiece 122a maintains the contact state of the sensor unit 123a with the concha, which is the test site, in a state of being inserted into the ear canal of the right ear.

FIG. 2 is a partial cross-sectional view of the measuring device 100 of FIG. Specifically, FIG. 2 is a partial cross-sectional view including a first measuring unit 120a for measuring information on blood flow in the right ear. However, in FIG. 2, some details of the internal mechanism of the first measuring unit 120a are omitted.

As schematically shown in FIG. 2, the sensor unit 123a includes a light emitting unit 124 and a light receiving unit 125 as a measuring mechanism. The light emitting unit 124 irradiates the measurement light to the concha of the right ear, which is the test site. The light receiving unit 125 acquires reflected light (scattered light) from the tissue inside the concha of the ear with respect to the irradiated measurement light. The photoelectric conversion signal of the scattered light received by the light receiving unit 125 is transmitted to a control unit included in the measuring device 100 or a control unit included in an electronic device communicably connected to the measuring device 100 by wire or wirelessly.

The light emitting unit 124 emits laser light, for example. The light emitting unit 124 irradiates the test site with laser light having a wavelength capable of detecting a predetermined component contained in blood, for example, as measurement light. The light emitting unit 124 is composed of, for example, one LD (laser diode: Laser Diode).

The light receiving unit 125 receives scattered light of the measurement light from the test site as biological information. The light receiving unit 125 is composed of, for example, a PD (photodiode: Photo diode).

As shown in FIG. 2, the main body 121a includes a speaker unit 126 inside. The speaker unit 126 generates sound based on the input voice data.

The first connecting portion 130a has two lid portions 131a and a damper portion 132a provided between the two lid portions 131a. The first connecting portion 130a connects the mounting portion 110 and the first measuring portion 120a at the first end 110a of the mounting portion 110. Although the first connecting portion 130a shown in FIG. 2 uses the connecting portion shown in FIG. 3 described later, a connecting portion having another shape described later may be used. Further, on the way from the first end 110a of the mounting portion 110 to the first measuring portion 120a via the first connecting portion 130a, the connecting portion 117 provided at the first end 110a and the first measuring portion 120a are connected. There are connecting portions 127 provided, but these may be arbitrarily deleted.

The control unit included in the measuring device 100 or the control unit included in the electronic device communicably connected to the measuring device 100 by wire or wirelessly is tested as biometric information based on the photoelectric conversion signal received from the sensor unit 123a. Calculate blood flow at the site. Here, a blood flow measurement technique using Doppler shift will be described.

In the tissue of the living body, the scattered light scattered from the moving blood cells undergo a frequency shift (Doppler shift) due to the Doppler effect proportional to the moving speed of the blood cells in the blood. The control unit detects a beat signal (also referred to as a beat signal) generated by the interference of light from scattered light from a stationary tissue and scattered light from a moving blood cell. This growl signal expresses the intensity as a function of time. The control unit turns this growl signal into a power spectrum that expresses power as a function of frequency. In the power spectrum of this beat signal, the Doppler shift frequency is proportional to the velocity of the blood cells. Also, in the power spectrum of this beat signal, the power corresponds to the amount of blood cells. The control unit obtains the blood flow rate by multiplying the power spectrum of the beat signal by a frequency and integrating it.

The second measuring unit 120b measures information on blood flow, for example, in the concha of the left ear of the subject. The second measuring unit 120b has a configuration and a function symmetrical with respect to the first measuring unit 120a. That is, the second measuring unit 120b includes a main body 121b, an earpiece 122b, and a sensor unit 123b. The main body 121b, the earpiece 122b, and the sensor unit 123b realize the functions of the main body 121a, the earpiece 122a, and the sensor unit 123a, respectively, in the left ear.

When the measuring device 100 is also used as an earphone, sound such as music may be output from the measuring unit 120. This voice is output from the speaker unit 126, and is output into the ear canal of the user (subject) via the earpiece 122a and the earpiece 122b.

Referring to FIG. 1 again, the first connecting portion 130a connects the first end 110a of the mounting portion 110 and the first measuring portion 120a. The second connecting portion 130b connects the second end 110b of the mounting portion 110 and the second measuring portion 120b. In the present specification, when the first connecting portion 130a and the second connecting portion 130b are not distinguished, they are collectively referred to as the connecting portion 130.

The connecting unit 130 functions as a reducing unit that reduces vibration transmitted from the mounting unit 110 to the measuring unit 120. The connecting portion 130 functions as, for example, a damper. The connecting portion 130 may be configured to include an elastic material capable of reducing vibration. The connecting portion 130 may be composed of a spring, rubber, silicone resin, gel, cloth, sponge, paper or other member, or any combination thereof. The connecting portion 130 may be, for example, a fluid-filled damper having a fluid (that is, a liquid or a gas) inside. The fluid inside may be, for example, a viscous liquid.

FIG. 3 is a schematic view showing an example of the connecting portion 130. As shown in FIG. 3A, the connecting portion 130 includes two lid portions 131 and a damper portion 132 provided between the two lid portions 131. The lid portion 131 is, for example, a flat plate-shaped member. The lid portion 131 may have any flat plate shape including, for example, a circle and a rectangle. Of the two lids 131, one is connected to the mounting unit 110 and the other is connected to the measuring unit 120.

In the present specification, as shown in FIG. 3A, a view showing the connecting portion 130 when the flat plate-shaped lid portion 131 is viewed from the side surface is referred to as a side view of the connecting portion 130. In the present specification, a diagram showing the connecting portion 130 when the connecting portion 130 is viewed from one lid portion 131 side (that is, when viewed from a position where the two lid portions 131 overlap) is shown in the connecting portion 130. It is called a top view. FIG. 3B is a top view of the connecting portion 130, in which the lid portion 131 is omitted. Further, the direction from one of the two lid portions 131 toward the other is the direction in which the connecting portion 130 mainly vibrates, and hereinafter, in the present specification, the direction in which the connecting portion 130 mainly vibrates is the main direction of the connecting portion 130. It's called direction.

The damper portion 132 is composed of a member capable of reducing vibration. When the connecting portion 130 is a fluid-filled damper, the fluid is sealed in the outer surface of the damper portion 132 and the inside of the space covered by the lid portion 131.

In the example shown in FIG. 3, the damper portion 132 is a substantially sphere. That is, in the example shown in FIG. 3, the damper portion 132 has a spherical shape except for the joint portion with the lid portion 131. Here, the sphere may include an ellipsoid.

As shown in FIG. 2 above, the main direction of the first connecting portion 130a is substantially perpendicular to the surface formed by the first end 110a, which is the end portion of the mounting portion 110. That is, the main direction of the first connecting portion 130a is substantially parallel to the normal of the surface formed by the first end 110a of the mounting portion 110. As a result, the vibration from the first end 110a of the mounting portion 110 is reduced by the vibration of the damper portion 132 of the first connecting portion 130a. The main direction of the first connecting portion 130a may be a direction other than substantially perpendicular to the surface formed by the first end 110a of the mounting portion 110. Here, the surface formed by the first end 110a of the mounting portion 110 may be, for example, a surface formed by a portion of the end portion of the mounting portion 110 that faces the measuring portion 120. The surface formed by the first end 110a of the mounting portion 110 includes not only a perfect flat surface but also a curved surface. The second connecting portion 130b may also have the same configuration and function as the first connecting portion 130a.

The shape of the damper portion 132 is not limited to that shown in FIG. The damper portion 132 can have any shape. Various examples of the shape of the damper portion 132 will be described with reference to FIGS. 4 to 17.

FIG. 11 shows an example of a damper portion 132 in which two frustums are connected to each other on the bottom surface side having a larger area than the upper surface. In this case, the upper surfaces of the two frustums are joined to the lid 131, respectively. FIG. 12 shows an example of a damper portion 132 in which two frustums are connected to each other on the upper surface side having a smaller area than the bottom surface. In this case, the bottom surfaces of the two frustums are joined to the lid 131, respectively.

FIG. 18 is a diagram showing a measurement result of blood flow of a subject measured using an earphone type measuring device. The measurement was performed using a measuring device 100 having a connecting portion 130 and a measuring device not provided with the connecting portion 130. All of the measuring devices used in the experiment measure blood flow with the concha region as the test site. The connecting portion 130 of the measuring device 100 used in the experiment has a round shape (for example, the shape shown in FIG. 3) and is made of EPDM (ethylene propylene rubber). In the experiment, the blood flow was measured for 5 minutes in a static posture while the subject was wearing the measuring device. The experiment was carried out at room temperature with an environmental temperature of 22 ° C to 24 ° C.

When a measuring device not provided with the connecting portion 130 is used, the position of the measuring portion shifts with respect to the concha, which is the test site, due to the influence of the vibration of the head of the subject. As a result, noise is generated in the blood flow measurement result, and as shown in FIG. 18, for example, a graph showing the blood flow partially protrudes upward. On the other hand, when the measuring device 100 provided with the connecting portion 130 is used, the vibration of the head of the subject is reduced by the connecting portion 130. Therefore, the position of the measuring unit 120 is unlikely to shift with respect to the concha, which is the test site. As a result, a graph of blood flow with less noise can be obtained.

As described above, the measuring device 100 according to the present embodiment includes a connecting portion 130 that reduces vibration between the mounting portion 110 and the measuring portion 120. Therefore, it is possible to reduce the vibration generated in the mounting unit 110 due to the movement of the head being transmitted to the measuring unit 120. Therefore, the vibration of the mounting portion 110 caused by the movement of the head is reduced at the connecting portion 130. As a result, the positional relationship between the test site and the measurement unit 120 is less likely to change. In this way, the measuring device 100 can improve the measurement accuracy of the biological information.

Several embodiments have been described for the complete and clear disclosure of this disclosure. However, the accompanying claims should not be limited to the above embodiments, and all modifications and alternatives that can be created by those skilled in the art within the scope of the basic matters set forth herein. It should be configured to embody a unique configuration. In addition, the requirements shown in some embodiments can be freely combined.

For example, in the above embodiment, it has been explained that the measuring unit 120 measures the information regarding the blood flow of the subject, but the information measured by the measuring unit 120 is not limited to the information regarding the blood flow. The measuring unit 120 may measure, for example, arbitrary information about the living body of the subject. Information about the living body is, for example, a change in electrical conductivity and resistance of the skin surface corresponding to pulse, heartbeat, blood flow velocity, blood pressure, and sweat gland activity, together with or in place of information about blood flow. It may include at least one of skin electrical activity (EDA: Electro-Dermal Activity), temporal changes in myocardial activity potential or activity current (electrocardiogram) that occur with the contraction of the heart, body temperature, and the like. , Not limited to these. Further, in the above embodiment, it has been explained that the measuring unit 120 measures the blood flow rate by utilizing the frequency shift due to the Doppler effect, but the measuring unit 120 is not limited to this.

For example, when the mounting location of the measuring device 100 is an arm or a foot, the measuring device 100 may be an arm wrist type or a foot band type, respectively. The measuring device 100 may be a necklace type or a headband type. For example, when the measuring device 100 is an arm wrist type, the wristband serves as a mounting portion 110, and a connecting portion is provided between the wristband and the measuring portion. The measuring device 100 may be attached to the forehead, chest, neck, back, abdomen, waist, calf or other appropriate place.

In the above embodiment, the first connecting portion 130a is provided between the first end 110a and the first measuring portion 120a of the mounting portion 110, and between the second end 110b and the second measuring portion 120b of the mounting portion 110. It was explained that the second connecting portion 130b is provided. However, the position where the connecting portion 130 is provided is not limited to this. For example, in the connecting portion 130, the first connecting portion 130a is provided between the first end 110a and the first measuring portion 120a of the mounting portion 110, and the second end 110b and the second measuring portion 120b of the mounting portion 110 are provided. A second connecting portion 130b may be provided between them, or at least one or more may be provided in a part of the arch-shaped mounting portion 110 instead. As a result, the transmission of vibration between the two components connected via the connecting portion 130 is reduced. In this case, for example, the mounting portion 110 may include a plurality of connecting portions 130.

Further, in the above embodiment, the first connecting portion 130a is provided between the first end 110a and the first measuring portion 120a of the mounting portion 110, and the second end 110b and the second measuring portion 120b of the mounting portion 110 are provided. It was explained that the second connecting portion 130b is provided between them. However, only one of the first connecting portion 130a and the second connecting portion 130b may be provided.

Further, in the above embodiment, the example in which the measuring device 100 is used alone is shown, but the measuring device 100 may be connected to the server via a network. The network may be any combination of the Internet, wireless LAN, mobile phone network and other appropriate networks. Also, the network may be wired, wireless or any combination of wired and wireless.

The biological information acquired by the measuring device 100 is transmitted to the server via the network. The server stores the biometric information acquired from the measuring device 100. In addition, the server processes the biological information acquired from the measuring device 100.

The server diagnoses the state of the user (subject) of the measuring device 100 based on the biological information acquired from the measuring device 100. The server may diagnose the state of the user of the measuring device 100 by appropriately combining the biometric information acquired from the measuring device 100 with, for example, information from another biometric device, input information, and the like. Based on the biological information acquired from the measuring device 100, the server, for example, the user's degree of relaxation, autonomic nerves, blood pressure, dehydration, heat stroke, blood flow, heart disease, pulse, heartbeat and other mental and physical conditions.
