Description

[Technical Field]

[0001] The present invention relates to a neckband-type biological information measuring device that measures the sleep state of a user. [Background technology]

[0002] Biometric information measuring devices are known that are worn on the human body and measure biological information through the skin. In order to obtain highly accurate biological information, one of the important conditions is that the measuring part equipped with a sensor does not come off the skin. Conventional products use bands or hinges to press the measuring part against the skin.

[0003] For example, Patent Document 1 discloses a neckband-type respiratory sound measuring device in which a measuring unit that acquires respiratory sounds from the skin of the user's anterior neck and a wearing unit that extends in an arc along the outer periphery of the user's neck are connected by a hinge. The respiratory sound measuring device of Patent Document 1 has a wearing detection sensor at the middle position of the inner circumferential surface of the measuring unit. The device also has a contact unit that is retractable relative to the inner surface of the measuring unit and biased in the protruding direction, and that displaces according to the shape of the user's anterior neck when worn on the neck and comes into surface contact with the anterior neck. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 7393792 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with the configuration described in Patent Document 1, there is a risk that part of the measurement unit may rise from the user's neck depending on the user's posture while sleeping. For example, when the user turns over in their sleep or their neck twists due to interference with a pillow or bed, part of the measurement unit may rise from the skin, making it difficult to follow. This can lead to errors in determining the wearing state by the wearing detection sensor, so there is room for improvement.

[0006] The present invention has been made in view of the above points, and has an object to provide a neckband-type biological information measuring device that can acquire highly accurate biological information. [Means for solving the problem]

[0007] A biometric information measuring device according to one aspect of the present invention comprises a measuring unit that is integrally constructed with a biometric information acquisition unit that contacts the neck to acquire biometric information and a contact detection unit that detects contact with the neck, a neckband formed in an arc shape to fit the outer circumference of the neck, and a joint structure that supports the measuring unit at the open end of the neckband so that it can swing freely.

[0008] According to this aspect, the measurement unit, which is an integrated structure of the biometric information acquisition unit and the contact detection unit, is supported by the neckband with a joint structure so that it can swing freely, so that even if the user's neck twists due to body movement while sleeping, the measurement unit can follow the skin and the biometric information acquisition unit and the contact detection unit can be brought into close contact with the skin, thereby enabling highly accurate biometric information to be acquired.

[0009] In the above aspect, the neckband may be provided with a restricting portion that restricts the swing range of the measuring portion.

[0010] According to the above aspect, it is possible to ensure that the measuring unit can conform to the skin while not allowing swinging beyond a predetermined swing range. This prevents the measuring unit from rotating to an unexpected position when wearing the biological information measuring device, and prevents the biological information acquisition unit and contact detection unit from moving to an unexpected measurement position on the skin. Furthermore, since the swing range of the measuring unit is restricted, wearing the device is easier.

[0011] In the above aspect, the neckband may comprise a neckband main body formed in an arc shape to follow the circumferential direction of the neck, and a joint portion provided with the joint structure, and the neckband main body and the joint portion may be connected via a hinge portion that supports the neckband main body and the joint portion so that the neckband can rotate freely between an expanded position in which the neckband is expanded into an arc shape and a folded position in which the joint portion is folded inward relative to the neckband main body.

[0012] This allows adjustment to provide a suitable contact pressure for users with different neck sizes, minimizing any discomfort felt when wearing the device.

[0013] In the above aspect, the neckband and the measuring unit may be detachably supported by the joint structure.

[0014] The biological information measuring device is a device that is worn around the neck while sleeping every night and used continuously. Therefore, there is a concern that dirt generated during sleep, such as sebum and sweat, may easily accumulate. However, by making the measuring unit removable as in this embodiment, it can be cleaned thoroughly and used in a hygienic state.

[0015] In the above aspect, the joint structure may be provided at a circumferentially intermediate position of the measurement unit, and in the measurement unit, the respiratory sound acquisition unit may be provided at a position closer to the circumferential tip side than the joint structure, and the contact detection unit may be provided at a position closer to the circumferential base side than the joint structure.

[0016] This allows for closer contact between the respiratory sound acquisition unit and the contact detection unit. In addition, since the respiratory sound acquisition unit and the contact detection unit are arranged side by side in the circumferential direction, the biological information measurement device can be configured compactly.

[0017] In the above aspect, the joint structure may be provided at a circumferentially intermediate position of the measuring section, one of a vibrator or a battery is provided at the circumferential tip end of the measuring section, and the other of the vibrator or the battery is provided at the circumferential base end of the measuring section.

[0018] In this way, by disposing the vibrator and the battery, which are relatively heavy members, at both ends in the circumferential direction, respectively, it is possible to achieve balance on both sides in the circumferential direction with the joint structure as a fulcrum.

[0019] In the above aspect, the neckband has an accommodation recess formed at one open end in which a part of the measuring unit is accommodated, and the measuring unit is connected to the neckband by the joint structure while accommodated in the accommodation recess.

[0020] By adopting such a configuration, the biological information measuring device can be configured compactly as a whole.

[0021] In the above aspect, a cushion part for preventing wobbling may be sandwiched between the measuring part and the joint part.

[0022] This allows the user to easily hold the measuring part and attach it to their neck, even in a dark place before going to sleep.It also prevents wobbling between the measuring part and the joint part, protecting the joint structure. [Effects of the Invention]

[0023] According to the present invention, it is possible to appropriately acquire breathing sounds from the neck of the user while reducing the discomfort felt by the user when wearing the device. [Brief explanation of the drawings]

[0025] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. The following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0026] <Configuration of the biological information measuring device> As shown in Figure 1, the biometric information measuring device 1 is worn by a user P around the neck Pn before going to bed to measure biometric information including inhalation and exhalation airflow sounds (hereinafter simply referred to as respiratory sounds) during sleep.

[0027] The biometric information measuring device 1 includes a measuring unit 40 for contacting the neck Pn to acquire biometric information of the user P, and a neckband 10 formed in an arc shape to fit along the outer circumference of the neck Pn and supporting the measuring unit 40 so that it can swing freely.

[0028] The up-down direction and the "user side" are defined based on the state in which the user P is wearing the bio-information measuring device 1, and the user side may be described as the "inside" and the opposite side as the "outside." The front (chest) side of the user P is defined as the front, and the back side is defined as the back. The circumference of the neckband 10 is defined as the "circumferential direction."

[0029] [Measurement part] As shown in FIG. 2, the measurement unit 40 includes a biometric information acquisition unit 50 for contacting the neck Pn to acquire biometric information, and a contact detection unit 55 for detecting that the inner surface 40a of the measurement unit 40 is in contact with the neck Pn. The biometric information acquisition unit 50 and the contact detection unit 55 are integrally configured. In this example, the biometric information acquisition unit 50 and the contact detection unit 55 are housed in a common housing case 41. This example also describes an example in which the biometric information acquisition unit 50 acquires respiratory sounds. Note that the biometric information acquired by the measurement unit 40 is not limited to respiratory sounds, and the measurement unit 40 may be configured to acquire other biometric information such as blood oxygen concentration, heart rate, blood pressure, and body movement.

[0030] -Storage case- As shown in Fig. 5, the storage case 41 is configured so that its vertical width fits within the neckband 10, and extends circumferentially along the neckband 10. As shown in Fig. 6, the storage case 41 is configured by fitting together an inner case 42 that is located on the inside when worn around the neck Pn and an outer case 43 that is located on the outside when worn, and a storage space Q is formed inside the storage case 41. Note that with regard to the measuring unit 40, the end on the open end side of the neckband 10 is defined as the "tip end," and the end circumferentially opposite the tip end is defined as the "base end." The same applies to the joint unit 20 and neckband main body 30 described below.

[0031] 2 and 4, the inner case 42 includes an inner plate that is formed to slope gently along the neck Pn and whose inner surface (shared with the inner surface 40a of the measurement unit 40) comes into contact with the skin of the neck Pn, and side plates that rise outward from the upper and lower ends, tip and base ends of the inner plate so as to surround the accommodation space Q. The inner plate of the inner case 42 has a circular sound conducting port 44 (see FIG. 6) formed in the vertical center and closer to the tip than the center, and a rectangular opening 45 (see FIG. 6) formed in the vertical center and closer to the base end than the center. The inner case 42 is configured to be approximately symmetrical up and down with respect to the center in the vertical direction.

[0032] The sound conducting port 44 is provided at a position corresponding to the biological information acquiring unit 50, and the opening 45 is provided at a position corresponding to the contact detecting unit 55. In other words, the vertical height positions of the biological information acquiring unit 50 and the contact detecting unit 55 are aligned. This makes it possible to achieve the same wearing comfort and measurement state regardless of whether the biological information measuring device 1 is worn on the left or right side of the neck Pn.

[0033] The outer case 43 of the storage case 41 includes an outer plate disposed opposite the bottom plate of the inner case 42, and side plates rising inward from the upper, lower, leading, and trailing ends of the outer plate to surround the storage space Q. The outer case 43 has a recessed portion 46 recessed inward at its circumferentially central position. A spherical bearing 47 (see FIG. 6 ) is provided at the vertical and circumferential center of the recessed portion 46, i.e., at the vertical and circumferential center of the measuring unit 40, to sway and detachably support the ball joint 23 (described later). Furthermore, a cushion portion 64 is sandwiched between the bottom surface of the recessed portion 46 and the ball joint 23. The material of the cushion portion 64 is not particularly limited, but for example, it is a silicone rubber sheet. The thickness of the cushion portion 64 in the inward and outward directions is not particularly limited as long as it does not cause the joint unit 23 to sway, but is, for example, approximately 1 mm to 2 mm.

[0034] As described above, the recessed portion 46 is formed in the outer case 43, and the ball joint 23 is supported by the spherical bearing 47 provided in the recessed portion 46. This allows the biological information measuring device 1 to be configured compactly, and has the effect of ensuring a wide swing range for the measuring unit 40.

[0035] Furthermore, by sandwiching a cushion part 64 between the bottom surface of the recessed part 46 and the ball joint 23, it is possible to prevent wobbling and maintain posture control. This makes it easy for the user to hold the measuring part 40 and attach it to the neck Pn, even in a dark place before going to sleep. Also, since wobbling between the ball joint 23 and the measuring part 40 can be prevented, the spherical bearing 47 can be protected.

[0036] As shown in Figure 4, a protrusion 48 is formed at the tip of the outer case 43, protruding toward the storage recess 21 formed on the inside of the side plate 26 of the joint part 20 described later, to regulate the swing range of the tip side of the measuring part 40.

[0037] -Vibrator and battery- As shown in FIG. 6 , the storage space Q of the storage case 41 accommodates a battery 61 for supplying power to the components of the biological information measurement device 1 and a vibrator 62 for applying stimulation to the neck Pn of the user P. The battery 61 is accommodated at the distal end of the storage space Q of the measurement unit 40, and the vibrator 62 is accommodated at the proximal end of the storage space Q. In this way, the measurement unit 40 is supported so as to be able to swing freely at the center in the vertical and circumferential directions of the measurement unit 40, and the vibrator 62 and the battery 61, which are relatively heavy members, are disposed at both distal and proximal ends in the circumferential direction. This provides the effect of achieving balance on both sides in the circumferential direction with the ball joint 23 as a fulcrum. Note that the positions of the battery 61 and the vibrator 62 may be interchanged, and the same effect can be obtained.

[0038] Vibrator 62 vibrates inward and outward under the control of a microcomputer (not shown) mounted on board 49. Vibrator 62 is controlled to vibrate, for example, when user P is snoring at a volume equal to or greater than a predetermined volume, or when user P is in an apneic state. The vibration of vibrator 62 is configured to be transmitted to housing case 41.

[0039] -Biometric information acquisition unit- As shown in FIG. 6, the biological information acquiring section 50 includes a vibrating sheet 51 for transmitting respiratory sounds, a sound collecting section 52 formed in the inner case 42, and a microphone 53.

[0040] The vibrating sheet 51 is attached so as to cover the sound conducting port 44 and to fit along the inner surface 40a of the inner case 42.

[0041] Sound collection section 52 is formed in a tapered shape with the inner diameter gradually narrowing from sound guide port 44 toward microphone 53. Note that this embodiment shows an example in which a thick portion is provided at a position to the left of the center of inner case 42, and sound collection section 52 is formed integrally with this thick portion. However, the configuration is not limited to this embodiment, and for example, sound collection section 52 may be formed separately from inner case 42 and attached to inner case 42 later.

[0042] The microphone 53 is attached to a substrate 49 arranged in the accommodation space Q, and is arranged so that its position, as viewed from the inside and outside, corresponds to that of the sound conducting port 44. The breathing sounds of the user P acquired through the vibrating sheet 51 are transmitted to the microphone 53 via the sound collecting unit 52.

[0043] In this disclosure, the term "microphone" is used to broadly encompass devices, apparatuses, and circuits that convert sound waves into electrical signals, as well as sound sensors, such as MEMS microphones, used in such devices, and is not particularly limited in its specific configuration. Meanwhile, in this embodiment, for the sake of convenience, the term "microphone" is used to refer to a sound sensor, such as a MEMS microphone, that acquires breathing sounds. However, this is done for the sake of convenience and is not intended to limit the meaning of the term "microphone."

[0044] -Contact detection section- The contact detection unit 55 is used to detect whether the biological information measurement device 1 is attached to the neck Pn. In this embodiment, an example is shown in which an optical sensor 56 is used as the contact detection unit 55. In this example, the opening 45 is covered with a translucent cover member 57 and is used as a measurement window for passing measurement light of the optical sensor 56. The contact detection unit 55 (optical sensor) is mounted on, for example, a common substrate 49 together with the microphone 53.

[0045] The contact detection unit 55 is not limited to an optical sensor, and other types of contact sensors may be used. When an optical sensor is used as the contact detection unit 55, it may function as the contact detection unit 55 and also as a sensor (biological information acquisition unit) for measuring other biological information (for example, blood oxygen concentration, heart rate, blood pressure, body movement, etc.). Furthermore, an optical sensor (biological information acquisition unit) for measuring other biological information (for example, blood oxygen concentration, heart rate, blood pressure, body movement, etc.) may be provided separately from the contact detection unit 55.

[0046] -Other configurations- As shown in FIG. 4, the power button 58 is configured, for example, as a push button that protrudes from the outside of the side panel of the measurement unit 40, allowing the user P to turn the power of the biological information measurement device 1 on and off.

[0047] The monitor lamp 59 is configured by, for example, a light-emitting diode. By looking at the light-emitting state of the monitor lamp 59, the user P can check the power on / off state, communication state, charging state, etc. of the biological information measuring device 1.

[0048] Although not shown, the device may also include a communication module for transmitting the measurement results from the measurement unit 40 to an external device (for example, see the terminal device 80 in FIG. 1).

[0049] [Neckband] 1 and 2, the biological information measuring device 1 includes a neckband 10 formed in an arc shape (for example, a substantially semicircular shape) so as to fit along the outer periphery (circumferential direction) of the neck Pn. One open end of the neckband 10 is formed with an accommodation recess 21 that is recessed in an L shape when viewed from the top, bottom, and rear to accommodate a measuring unit 40. While accommodated in the accommodation recess 21, the measuring unit 40 is supported by the neckband 10 by a joint structure (ball joint 23 and spherical bearing 47).

[0050] In this disclosure, the term "arc-shaped" is used as a broad concept that includes something that is roughly arc-shaped to fit the shape of the neck Pn, for example, including an arc that is part of a substantially perfect circle, an arc that forms part of an ellipse, or an arc in which part of the arc is slightly bulged or the diameter of the arc changes midway through the neckband 10, but which is roughly arc-shaped overall.

[0051] As shown in FIGS. 2 and 3, the neckband 10 includes a neckband body 30 and a joint part 20.

[0052] -Neckband body- The neckband body 30 extends in an arc shape along the periphery of the neck Pn and forms a portion to be worn around the neck Pn. The neckband body 30 (1) can be worn around the back of the neck Pn by the user P with both hands spreading both open ends of the vital information measurement device 1, or by the user P holding the vital information measurement device 1 in one hand and spreading the measurement unit 40 outward while pressing it against the back of the neck Pn; (2) has elasticity sufficient to hold the neck Pn from the outside in the circumferential direction so that a portion or all of the inner surface 10a of the vital information measurement device 1 fits tightly against the neck Pn when the user P releases their hand; and (3) preferably has strength sufficient to withstand continuous use. The specific structure and materials of the neckband body 30 are not particularly limited as long as the above conditions (1) to (3) are satisfied. For example, the neckband body 30 can be made of an elastic structure in which a leaf spring is surrounded by elastomer resin, or made of elastic polypropylene resin. However, the technology of the present disclosure is not limited to employing a plate spring structure for the neckband body 30 or using elastomer resin or polypropylene resin.

[0053] One end 31 (hereinafter referred to as the base end 31) of the neckband main body 30 is connected to the joint part 20 via a hinge part 70. The other end 32 (tip end) of the neckband main body 30 forms the other open end of the neckband 10, and is pressed against the back of the neck of the user P when the biological information measuring device 1 is worn around the neck Pn.

[0054] -Joint part- 3 to 6, the joint part 20 is connected to the base end 31 of the neckband main body 30 via a hinge part 70. As shown in Fig. 6, the joint part 20 has a base part 25 that is L-shaped when viewed from the top and bottom (an inverted L-shape in Fig. 6), and side plates 26 that rise inward from the top and bottom ends of the base part 25, and the aforementioned storage recess 21 is formed by the base part 25 and the side plates 26.

[0055] Pedestal 24 that fixedly supports ball joint 23 (corresponding to a joint structure) is provided in the vertical center closer to the tip than the center of base 25. Ball joint 23, which is fixedly supported by pedestal 24, has a configuration in which a sphere is provided at the tip of a shaft that extends inward, and the sphere is supported by spherical bearing 47 so as to be detachable and swingable.

[0056] A part of the measuring unit 40 is accommodated inside the side plate 26 of the accommodation recess 21, and a predetermined range of vertical swinging is ensured according to the vertical spacing of the side plate 26, and the side plate 26 restricts swinging so as not to exceed a predetermined amount.

[0057] In this embodiment, the tip of the measuring unit 40 is configured to protrude further toward the circumferential tip side than the tip of the accommodating recess 21. However, this is not limited to the configuration shown in Figure 6, and the entire measuring unit 40 may be accommodated in the accommodating recess 21, or the amount of protrusion from the accommodating recess 21 may be greater than that shown in Figure 6.

[0058] The side plate 26 is formed so that its width gradually increases in the inward and outward directions from the tip (left end in FIG. 6) to the base end (right end in FIG. 6). For example, as shown in FIG. 7, when the measurement unit 40 is rotated clockwise from the state shown in FIG. 6, the base end 40b enters the inside of the base end 26a of the side plate 26. In this way, the measurement unit 40 is restricted so that it does not swing beyond a predetermined swing range while ensuring a predetermined swing range. In other words, the interaction between the base end 40b and the base end 26a functions as a restrictor that restricts the swing range of the measurement unit 40.

[0059] Furthermore, the tip 20a of the joint part 20 is configured so that when the measuring part 40 swings up and down or inward and outward, the protrusion 48 of the measuring part 40 or the underside of the outer case 43 comes into contact with the tip 20a, thereby restricting the range of swing in the up and down or inward and outward directions. Specifically, at the tip 20a of the joint part 20, the side plate 26 is configured so that its width in the inward and outward directions is slightly wider at a position corresponding to the up and down direction of the protrusion 48, and is inclined so that its width in the inward and outward directions narrows from there toward the tip. This configuration restricts the swing range of the tip side of the measuring part 40 in the outward and up and down directions. In other words, the interaction between the protrusion 48 and the tip 20a realizes the function of a restricting part that restricts the swing range of the measuring part 40.

[0060] As described above, the joint part 20 is provided with the ball joint 23 as a joint structure that swingably connects the measuring part 40. The joint part 20 also functions as a restricting part that restricts the swing range of the measuring part 40.

[0061] An absorber 28 for absorbing vibrations of the vibrator 62 is provided on the inner surface of the base 25 and at a position outside the vibrator 62. This makes it possible to prevent abnormal noises caused by the vibration of the vibrator 62 even if the vibrator 62 vibrates at a position where it may come into contact with the base 25.

[0062] [Hinge] The hinge portion 70 supports the neckband main body 30 and the measuring portion 40 so that they can rotate freely between an unfolded position shown by the solid lines in FIG. 3 and a folded position shown by the imaginary lines in FIG.

[0063] As shown in FIG. 6 , the hinge unit 70 includes a rotation shaft unit 71 that forms a rotation axis AX, which is the central axis of the rotational movement, and a biasing means 72 that biases the joint unit 20 toward the bending position. The configuration of the rotation shaft unit 71 is not particularly limited, but can be realized, for example, by providing bearings (not shown) on both side walls of the base end 31 of the neckband body 30 or the base end of the joint unit 20, and rotatably supporting the rotation shaft unit 71 on the bearings. In this embodiment, a torsion coil spring is used as the biasing means 72, but other biasing means may also be used. Although not shown, the hinge unit 70 may be a so-called hinge spring, in which a hinge and a spring are integrally configured.

[0064] Here, the unfolded position is a position where the measuring unit 40 is maximally opened outward, as shown by the solid lines in Fig. 3, and when the measuring unit 40 is in the unfolded position, the biological information measuring device 1 as a whole is configured to have an arc-like shape. In the unfolded position, for example, the base end 31 of the neckband main body 30 and the base end of the joint part 20 abut against each other, and the angle between the neckband main body 30 and the measuring unit 40 is locked so that it does not widen further outward (see dashed frame ST in Fig. 4). The folded position is a position where the measuring unit 40 is folded inward relative to the neckband main body 30, as shown by the imaginary lines in Fig. 3.

[0065] The movable range R11 between the unfolded position and the folded position is not particularly limited, but is, for example, about 40 degrees. A rotation range of about 40 degrees can accommodate users P with a wide range of body types. However, the movable range (rotation range) is not limited to about 40 degrees, and may be, for example, more than 40 degrees. The degree to which the biological information measuring device 1 is opened changes depending on the rotation between the unfolded position and the folded position.

[0066] <Effects of the embodiment> As described above, according to this embodiment, the biological information measuring device 1 includes a measuring unit 40 and a neckband 10. The measuring unit 40 is an integral unit of a biological information acquiring unit 50 that acquires biological information by contacting the neck Pn, and a contact detecting unit 55 that detects contact with the neck. The neckband 10 is formed in an arc shape to fit the outer periphery of the neck Pn, and is provided at its open end with a ball joint 23 as a joint structure that supports the measuring unit 40 so that it can swing freely.

[0067] With this configuration, the measuring unit 40, in which the biometric information acquiring unit 50 and the contact detecting unit 55 are integrally configured, is supported so as to be able to swing freely by the ball joint 23, so that even if the neck of the user P twists due to bodily movements while sleeping, the measuring unit 40 can follow the skin of the neck Pn, and the biometric information acquiring unit 50 and the contact detecting unit 55 can be brought into close contact with the skin. This makes it possible to acquire biometric information with high accuracy.

[0068] In the embodiment, the neckband 10 is provided with a restricting portion that restricts the swing range of the measuring portion 40.

[0069] This ensures that the measurement unit 40 can conform to the skin while not allowing swinging movements beyond a predetermined swing range. This prevents the measurement unit 40 from rotating to an unexpected position and the biological information acquisition unit 50 and contact detection unit 55 from moving to an unexpected measurement position on the skin when the biological information measurement device 1 is worn. Furthermore, since the swing range of the measurement unit 40 is restricted, the device is easier to wear.

[0070] In this embodiment, the neckband 10 includes a neckband main body 30 formed in an arc shape that follows the circumferential direction of the neck Pn, and a joint section 20 that is provided with a joint structure. The neckband main body 30 and the joint section 20 are connected via a hinge section 70 that supports the neckband main body 30 and the joint section 20 so that they can rotate freely between an unfolded position and a folded position.

[0071] This allows adjustment to provide a suitable contact pressure for users P with different cervical (neck) sizes, minimizing discomfort when wearing the device.

[0072] In this embodiment, the neckband 10 and the measuring unit 40 are supported by a joint structure so as to be detachable.

[0073] By making the measuring unit 40 removable in this way, for example, every corner of the accommodation recess 21 can be cleaned, and the device can be used in a hygienic state.

[0074] In the embodiment, the ball joint 23 as a joint structure is provided at the circumferential middle position of the measuring unit 40, and one of the vibrator 62 or the battery 61 is provided at the circumferential tip end of the measuring unit 40, and the other of the vibrator 62 or the battery 61 is provided at the circumferential base end of the measuring unit 40.

[0075] In this way, by disposing the vibrator 62 and the battery 61, which are relatively heavy members, at both ends in the circumferential direction, respectively, it is possible to achieve balance on both sides in the circumferential direction with the ball joint 23 as a fulcrum.

[0076] In this embodiment, a cushion part 64 is sandwiched between the bottom surface (inner surface) of the spherical bearing 47 of the measuring part 40 and the ball joint 23.

[0077] This allows the user to easily hold the measurement unit 40 and attach it to the neck Pn, even in a dark place before going to bed. Furthermore, since the measurement unit 40 can be prevented from wobbling, the spherical bearing 47 can be protected.

[0078] <Modification> As described above, the embodiments have been described as examples of the technology disclosed in this application. However, the technology in this disclosure is not limited to these, and can be applied to embodiments in which appropriate modifications, substitutions, additions, omissions, etc. are made.
