Description

The present invention relates to a neckband type respiratory sound measuring device that measures a subject's sleep state.

Sleeping snoring may cause inconvenience to people around you, or you may become apnea from the snoring and develop obstructive apnea syndrome. Therefore, there is a demand for a respiratory sound measuring device that measures the sleep state of a subject and stimulates the subject in order to change the posture of the subject when snoring or sleep apnea occurs.

Patent Document 1 discloses a method in which a microphone is attached around the neck of each patient to record the sound received by the microphone during the sleep of the patient.

JP-A-2007-202939

In the neckband type respiratory sound measuring device, it is desirable to acquire the respiratory sound of the airway directly in the neck of the subject from the viewpoint of improving the measurement accuracy of the respiratory sound. Further, in the neckband type respiratory sound measuring device, when acquiring the respiratory sound of the subject's direct airway, it is desired that the contact pressure be appropriate. Therefore, conventionally, as in Patent Document 1, a C-shaped neckband having both ends extended to both front sides of the subject has been used. However, depending on the subject, the neckband type breath sound measuring device having such a configuration may cause a great sense of discomfort when worn.

For example, in the case of a general man, the size around the neck is about 36 to 47 cm, and some men are outside the general size. Therefore, several types of size lineups (for example, S, M, L, etc.) are provided as neckbands. However, even among subjects who use neckbands of the same size band, the shape of the neck and the dimensions around the neck are various, and there is a problem that it is difficult to accurately adjust the size for each subject with a general-purpose product. In particular, during sleep, the subject may feel uncomfortable and interfere with comfortable sleep. In addition, the subject may sleep sideways at bedtime, and if one side of the subject's neck is pressed against the bedding, the other side may rise, which may interfere with accurate measurement.

That is, the present invention has been made in view of this point, and is a neckband type respiratory sound measuring device capable of suitably acquiring breath sounds from the neck of the subject while alleviating the discomfort when the subject is worn. The purpose is to provide.

The sleep state measuring device according to one aspect of the present invention includes a respiratory sound measuring unit that abuts on the anterior lateral portion of the subject's neck and measures the subject's breath sounds, and a respiratory sound measuring unit that follows the outer periphery of the subject's neck. It is provided with an elastic mounting portion that extends in an arc shape and is configured such that the tip abuts on the posterior lateral portion of the subject's neck opposite to the anterior lateral portion.

According to this aspect, since the respiratory sound measuring unit is brought into contact with the anterior lateral portion of the subject's neck, that is, the throat, the respiratory sound can be suitably obtained from the subject's neck. On the other hand, the other end of the mounting portion is brought into contact with the rear side portion on the opposite side to the front side portion. That is, the wearing portion is not extended to the front side of the subject. Thereby, the feeling of tightening the neck of the subject can be alleviated. Further, when the subject lies sideways so that the contact portion side faces up, the wearing portion can be prevented from being sandwiched between the bedding and the subject. As a result, it is possible to prevent the contact portion from being lifted from the subject's neck when the wearing portion is pushed by the bedding. In addition, it is possible to prevent the wearing portion from rubbing against bedding or the like while sleeping.

In the sleep state measuring device of the above aspect, the breath sound measuring unit and the neckband are connected by a hinge.

As a result, it is possible to adjust the contact pressure so that it is suitable for subjects with different neck (neck) sizes as compared with the case of using an integrated neckband, and it is possible to reduce the discomfort when wearing it. Can be reduced.

According to the present invention, it is possible to preferably obtain breath sounds from the neck of a subject while alleviating the discomfort when the subject is worn.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of preferred embodiments is merely exemplary and is not intended to limit the present invention, its applications or its uses.

<Configuration of breath sound measuring device>
As shown in FIGS. 1 and 8, the respiratory sound measuring device 1 is attached to the subject's neck Pn (hereinafter, simply referred to as the neck Pn) by the subject P before going to bed, and the inspiratory / expiratory airflow during sleep. It is for measuring sound (hereinafter, simply referred to as breath sounds). Specifically, the respiratory sound measuring device 1 is a neckband type device, and is configured to be wearable along the circumferential direction of the subject's neck. The breath sound measuring device 1 is an example of a sleep state measuring device that measures the sleeping state of the subject P.

Specifically, as shown in FIG. 3, the respiratory sound measuring device 1 has a neckband type mounting portion 30 formed in an arc shape (for example, a substantially semicircular shape) and a measurement for measuring breath sounds. The portion 40 has a structure in which the portion 40 is connected by a hinge portion 60 having a well-known structure. The respiratory sound measuring device 1 is configured so that the opening angle θ between the open ends in the deployed state exceeds 90 degrees when viewed from the center thereof. In other words, the outer shape of the breath sound measuring device 1 in the deployed state (see FIG. 5) is configured to be less than 270 degrees with respect to the virtual circle extending in the circumferential direction along the outer shape. In FIG. 3, AX indicates a rotation axis.

In the following description, the vertical direction and the horizontal direction are defined with reference to the wearing state of the respiratory sound measuring device 1 of the subject P. Further, the front (chest) side of the subject P is defined as the front, and the back side is defined as the back. Further, the "subject side" shall be defined based on the wearing state of the breath sound measuring device 1, and the subject side shall be "inside" and the opposite side shall be "outside" in the explanation of the wearing unit 30 and the measuring unit 40. May be explained. Further, the surface of the respiratory sound measuring device 1 on the Pn side of the subject's neck is referred to as "inner surface 10a of the respiratory sound measuring device 1" or simply "inner surface 10a". That is, the "inner surface 10a of the breath sound measuring device 1" is a concept including the inner surface 42c of the measuring unit 40 in addition to the inner surface of the mounting unit 30.

《Mounting part》
As shown in FIG. 3, the mounting portion 30 extends in an arc shape along the outer circumference of the neck Pn. One end 31 (hereinafter, referred to as a base end 31) of the mounting portion 30 is connected to the measuring portion 40 via the hinge portion 60. The tip of the measuring unit 40 constitutes one open end of the breath sound measuring device 1. The other end 32 of the mounting portion 30 (hereinafter referred to as the pressing portion 32) constitutes the other open end of the respiratory sound measuring device 1. That is, the pressing portion 32 is integrally configured with the wearing portion 30, and is pressed against the subject when the breath sound measuring device 1 is attached to the neck Pn.

In the wearing state of the subject P shown in FIG. 3, when the contact portion 70 described later is in contact with the skin of the right anterior neck Pf1 of the subject P, the pressing portion 32 is the left rear neck of the subject P. It is designed to be pressed against Pr1. On the other hand, as shown in FIG. 8, in the mounting portion 30, when the contact portion 70 is in contact with the skin of the left anterior neck Pf2 of the subject P in the wearing state of the subject P, the pressing portion 32 is the subject P. It comes into contact with the right posterior neck Pr2. In other words, the measuring unit 40 and the pressing unit 32a are arranged asymmetrically with respect to the left-right center of the neck Pn. The left-right center is defined, for example, at the center position of the Adam's apple when viewed from the front of the subject P.

Here, the anterior neck Pf is a surface around the neck Pn of the subject P, which is anterior to the virtual plane passing through the center of each ear of the subject P, or a surface anterior to the anterior-posterior center of the neck Pn. It shall point. In particular, the contact position of the contact portion 70 is preferably the skin near the trachea (for example, the throat) in the anterior neck Pf, and the contact position of the contact portion 70 is closer to the front even in the front neck Pf. Set to position. Further, the posterior cervical Pr is a surface around the cervical Pn of the subject, which is posterior to the virtual plane passing through the center of each ear of the subject P, or a surface posterior to the anterior-posterior center of the cervical Pn. Shall refer to. The pressing portion 32 is pressed against the skin of the posterior neck Pr. That is, the pressing portion 32 is pressed against the skin behind the ear of the subject P. As a result, the respiratory sound measuring device 1 of the present embodiment has a conventional configuration as shown in Patent Document 1 (the respiratory sound measuring device has a C shape so that the open ends are on the front side of both ears of the subject P. The discomfort (for example, tightening feeling) of the subject P can be alleviated as compared with the configuration in which both open ends thereof are pressed against the skin of the subject P on the front side of both ears). In addition, since large blood vessels pass through the inside of the ear in the neck in the vertical direction, it is possible to make it difficult to obstruct the passing blood flow as compared with the case of pressing from both sides of the ear. From this point of view, the discomfort (for example, tightening feeling) of the subject P is alleviated.

The wearing portion 30 can be (1) worn by the subject P with both hands with both open ends of the breath sound measuring device 1 spread to both sides from the back side of the neck Pn toward the neck Pn, and (2). It has an elastic force for sandwiching the neck Pn from the outside in the circumferential direction so that at least a part of the inner surface 10a of the breath sound measuring device 1 comes into close contact with the neck Pn when the subject P releases the hand (3). ) It is preferable that the strength is sufficient to withstand continuous use. As long as the above conditions (1) to (3) are satisfied, the specific structure and constituent material of the mounting portion 30 are not particularly limited. For example, an elastic structure in which the leaf spring is surrounded by an elastomer resin can be adopted as the mounting portion 30, or an elastic polypropylene resin can be adopted. However, the technique of the present disclosure is not limited to adopting a leaf spring structure for the mounting portion 30 or using an elastomer resin or a polypropylene resin.

《Hinge part》
The hinge portion 60 supports the mounting portion 30 and the measuring portion 40 so as to be rotatable between the unfolding position shown by the solid line in FIG. 3 and the bending position shown by the virtual line in FIG.

The unfolded position is a position where the measuring unit 40 is opened to the maximum outward, and the inner surface 10a becomes substantially flat at the joint portion between the two. That is, when the measuring unit 40 is in the deployed position, the breath sound measuring device 1 as a whole is configured to have an arc shape. In the unfolded position, for example, the tip end portion of the mounting portion 30 and the base end portion of the measuring unit 40 are brought into contact with each other, and the angle between the mounting unit 30 and the measuring unit 40 is locked so as not to widen further outward. Will be done.

The bent position is a position where the measuring unit 40 is bent inward with respect to the mounting unit 30 (see FIG. 2). At the bent position, for example, the base end portion of the measuring portion 40 is brought into contact with the outer inner wall of the mounting portion 30, and is locked so as not to bend further inward.

The movable range R11 between the unfolded position and the bent position is not particularly limited, but is, for example, about 40 degrees. If there is a rotation range of about 40 degrees, it is possible to handle a wide range of body types of the subject P. However, the movable range (rotation range) is not limited to about 40 degrees, and for example, the movable range may be less than 40 degrees or more than 40 degrees. The degree of opening of the breath sound measuring device 1 changes due to the rotation between the unfolded position and the bent position.

As shown in FIG. 6, the hinge portion 60 urges the rotation shaft portion 61 constituting the rotation shaft AX, which is the central axis of the rotation operation, and the measurement unit 40 toward the bent position. The means 62 is provided.

The configuration of the rotating shaft portion 61 is not particularly limited, but for example, as described above, bearings are provided on the base end sides of both side walls of the inner case 42, and the rotating shaft portion 61 is rotatably supported on the bearings. It can be realized by.

The configuration of the urging means 62 is not particularly limited, but here, an example using a torsion coil spring is shown. One end of the urging means 62 is fixed to the storage case 41, and the other end is fixed to the mounting portion 30. Although not shown, a so-called hinge spring in which a hinge and a spring are integrally formed may be used as the hinge portion 60. Also in this case, the hinge spring is fixed to each of the accommodating case 41 and the mounting portion 30.

Here, the urging force of the urging means 62 is configured to be larger than the urging force of the compression coil spring 78. With such a configuration, (1) the alignment of the outline according to the body shape (particularly the size of the neck) of the subject is performed by the action of the urging means 62, and (2) by the action of the compression coil spring 78. It is possible to more preferably realize the operation of adjusting the angle of the contact surface 70b of the contact portion 70 so as to be along the measurement location (skin surface) of the respiratory sound of the subject's neck Pn. Here, a partition wall 44b may be provided in the accommodation space Q on the base end side of the measuring unit 40 in order to prevent foreign matter from entering from around the hinge unit 60. By providing the partition wall 44b on the accommodation space Q side in this way, it is possible to obtain a dustproof effect while increasing the mobility of the hinge portion 60. As shown in FIG. 5, a partition wall 44 in which the partition wall 44a and the partition wall 44b described later are integrally formed may be provided. With such a configuration, the number of constituent members can be reduced and the workability of the assembly work can be improved. In FIG. 9, the partition wall 44 is provided with hatching that rises to the right.

《Measurement unit》
-Accommodation case-
As shown in FIGS. 5 and 6, the measuring unit 40 has a storage case 41 in which a storage space Q is formed inside by fitting the inner case 42 and the outer case 43.

The inner case 42 includes a bottom plate formed so as to be convex outward, and a side plate that rises outward from the upper and lower ends of the bottom plate and the tip so as to surround the accommodation space Q. On the bottom plate of the inner case 42, a circular first opening 42a is formed at a substantially central position above and below the tip side, and a rectangular second opening 42b is formed at a substantially center position above and below in the circumferential direction. ..

The contact portion 70 is inserted into the first opening 42a from the inside of the housing case 41. Then, the contact portion 70 is prevented from coming off by the accommodation case 41 by the flange portion 70c (see FIG. 6) formed at the base end portion. The second opening 42b is a measurement window for passing measurement light, for example, when an optical human detection sensor 59 is used to detect whether or not the breath sound measuring device 1 is attached to the neck Pn. Used as. The second opening 42b is not always necessary, and is not necessary, for example, when the human detection sensor 59 is of a method other than the optical type or when the human detection sensor 59 itself is not provided.

As shown in FIG. 9, in order to rotatably support the rotation shaft portion 61 of the hinge portion 60, which will be described later, at the base end portions (end portions on the mounting portion 30 side) of the side walls of the inner case 42, respectively. Bearing 42e is provided. The configuration of the bearing 42e is not particularly limited, but for example, a shaft insertion hole slightly larger than the outer shape of the rotating shaft portion 61 is formed at the base end portions of both side walls of the inner case 42.

As shown in FIGS. 2 to 4, the outer case 43 of the storage case 41 has an upper plate arranged so as to face the bottom plate of the inner case 42, and upper and lower ends of the upper plate so as to surround the above-mentioned storage space Q. And a side plate that rises inward from the tip. The base end side of the upper plate of the outer case 43 is formed so as to cover a part of the hinge portion. After aligning the inner case 42 and the outer case 43, the storage case 41 is screwed by a screw 46 (see FIG. 6) inserted into a screw hole 45 (see FIG. 6) formed in the bottom plate of the inner case 42. It is fixed.

As shown in FIG. 6, in the accommodation space Q of the accommodation case 41, a first substrate 73 to which the microphone 74 is attached and a second substrate on which electronic components and the like for processing the breath sounds acquired by the microphone 74 are mounted. 50 and a battery 51 for supplying power to each component of the breath sound measuring device 1 are housed. The first substrate 73 and the second substrate 50 are connected by a flexible cable 76. The material for forming the storage case 41 may be the same as that of the mounting portion 30, or may be different from each other.

Although not shown, the side plate of the measuring unit 40 is provided with an insertion port that opens toward the outside so that a communication / charging cable can be inserted into the connector 55 via the insertion port. It has become.

-Abutment part-
As shown in FIGS. 2 and 6, the respiratory sound measuring device 1 includes a contact portion 70 provided so as to project from the inner surface 42c of the inner case 42 toward the inside (neck Pn side of the subject P). .. A sound guide port 70a for introducing the breath sounds of the subject is formed at the tip of the contact portion 70, and a ring-shaped contact surface 70b is formed so as to surround the sound guide port 70a. The contact surface 70b comes into contact with the neck Pn when the breath sound measuring device 1 is attached. In this way, by providing the contact surface 71a on the protruding portion 70, the contact area with the neck Pn can be widened, the breath sounds can be prevented from leaking to the outside, and the sound collecting effect can be enhanced. A hollow space 70d (see FIG. 7) may be provided inside the contact portion 70 to reduce the weight while maintaining the strength.

As shown in FIG. 6, the base end surface of the contact portion 70 is recessed in a substantially rectangular shape at the central portion, and the rectangular first substrate 73 is fitted therein. A microphone 74 is attached to substantially the center of the inner surface of the first substrate 73.

In the present disclosure, the term "microphone" is used in a concept that broadly includes devices, devices, and circuits that convert sound waves into electrical signals, and sound sensors such as MEMS microphones used in such devices. The specific configuration is not particularly limited. On the other hand, in the present embodiment, for convenience of explanation, the term "microphone" is used for a sound sensor for acquiring breath sounds such as a MEMS microphone. However, this is done for convenience of explanation and is not intended to limit the meaning of the term "microphone".

The material constituting the contact portion 70 is not particularly limited as long as it has sufficient hardness (predetermined hardness) to maintain the cylindrical shape of the second sound-conducting space RS2 described later. For example, a plastic resin (for example, polyoxymethylene) can be used as the material constituting the contact portion 70. Further, for example, polypropylene or silicon resin having a hardness of 50 or more may be used.

As shown in FIG. 6, the contact portion 70 is provided with a sound guiding space RS for guiding the breath sounds introduced from the sound guiding port 70a to the microphone 74. The sound-conducting space RS is composed of a first sound-conducting space RS1, a second sound-conducting space RS2, and a third sound-conducting space RS3. The first sound-conducting space RS1 is a space formed by a sound-conducting hole 73a formed through the first substrate 73 at a position corresponding to the microphone 74 in the front-back direction. A tapered sound collecting portion 70e (see FIG. 2) whose inner diameter gradually narrows toward the microphone 74 is formed in the sound guiding port 70a, and the space inside the sound collecting portion 70e is the third sound guiding space RS3 (FIG. 2). 6). Then, the first sound-conducting space RS1 and the third sound-conducting space RS3 are connected by a cylindrical second sound-conducting space RS2. A cylindrical sound insulating material 77 may be provided so as to abut the inner wall surface of the second sound guiding space RS2. By providing such a sound insulating material 77, it is possible to suppress the propagation of vibration generated by an impact or the like given from the outside to the respiratory sound measuring device 1 and the generation of solid-borne sound in the sound-conducting space RS. .. The vibration of the breath sound measuring device 1 is generated by rubbing the breath sound measuring device 1 with bedding, the subject's hand, or the like when, for example, the subject P changes his / her posture while sleeping.

The material forming the sound insulating material 77 is not particularly limited, but it is difficult to absorb the sound waves of the breath sounds acquired from the neck Pn and passing through the second sound guiding space RS2 while absorbing the solid vibration from the mounting portion 30. It is preferably formed of such a material. As the sound insulating material 77, for example, an elastic material such as silicon rubber can be preferably used.

A cover 75 that covers the first substrate 73 is attached to the base end portion of the contact portion 70. A compression coil spring 78 is provided between the cover 75 and the top plate of the outer case 43. When the breath sound measuring device 1 is attached to the neck Pn and the contact portion 70 is pressed against the neck Pn, the contact portion 70 is pushed into the accommodation space Q of the accommodation case 41, and the inner end surface of the attachment portion 30 The amount of protrusion of the contact portion 70 from the surface changes. Further, due to the action of the compression coil spring 78, the contact surface 70b comes into close contact with the skin of the neck Pn. As a result, the adhesion of the subject's neck Pn to the skin is enhanced, the wearing feeling of the subject P is improved, and the trace of the subject P's bite into the skin is less likely to remain.

FIG. 10 shows an example of a subject whose neck is thinner than that of FIG. In the example of FIG. 10, if the measuring unit 40 remains in the deployed position when the breath sound measuring device 1 is attached, the contact surface 70b of the contact portion 70 does not hit the neck Pn (see the virtual line in FIG. 10). .. In the present embodiment, since the hinge portion 60 is urged toward the bent position, the measuring portion 40 rotates toward the subject neck Pn side (inside). FIG. 10 shows an example in which the rotation angle R12 (R11> R12) is rotating. Further, when the measuring unit 40 enters the neck Pn side, the inner surface 42c of the measuring unit 40 in the vicinity of the neck Pn also tilts inward. In the present embodiment, the angle of the contact surface 70b of the contact portion 70 changes according to the force received from the neck Pn of the contact surface 70b (see R22 in FIG. 10). That is, the angle of the contact surface 70b of the contact portion 70 changes along the neck Pn. Further, since the urging force of the compression coil spring 78 acts on the contact portion 70, the adhesion of the contact surface 70b to the subject neck Pn can be improved.

FIG. 11 shows an example of a subject whose neck is thicker than that of FIG. In the example of FIG. 11, the neck Pn does not fit inside the mounting portion 30, but as described above, the respiratory sound measuring device 1 does not open beyond the deployed position. The outer size of is expanded. Then, most of the contact portion 70 enters the accommodation space Q, and the amount of protrusion of the contact portion 70 from the measurement unit 40 is very small. By performing such an operation, the contact portion 70 is suppressed from biting into the subject's neck Pn. Further, also in this case, the urging force of the compression coil spring 78 acts to enhance the adhesion of the contact surface 70b to the subject's neck Pn.

Although FIGS. 10 and 11 show an example in which the length of the mounting portion 30 is longer than that in FIG. 3, the length of the mounting portion 30 may be different in this way, and the same effect can be obtained.

-Second board-
Returning to FIG. 6, the second substrate 50 is arranged on the bottom plate (plate on the subject side) of the inner case 42 so as to extend along the longitudinal direction of the measuring unit 40 (circumferential direction of the mounting unit 30). The second substrate 50 is fixed to the storage case 41. Specifically, the second substrate 50 is fitted and fixed to the partition wall 44, and the partition wall 44 is fitted and fixed to the inner case 42.

The second substrate 50 includes a control unit (not shown), a storage unit for storing measurement results (not shown), a communication module 53 for transmitting measurement results to an external device (for example, a terminal device 80), and a body position. / Accelerometer for detecting body movement (not shown), connector 55 for communicating with external devices and charging the battery, vibrator 56 for stimulating the subject, power button 57 (see FIG. 2) , A monitor lamp 58 for a subject (see FIG. 2), a human detection sensor 59, and the like are mounted. The control unit controls the operation of the breath sound measuring device 1 as a whole. The control unit is, for example, a microprocessor, and has a CPU, a memory, and the like. The control unit receives power from the battery 51 and operates based on a program or the like stored in a storage unit (not shown).

-Vibrator-
The vibrator 56 vibrates under the control of the control unit. The vibrator 56 is controlled to vibrate, for example, in a state in which the subject P is snoring at a predetermined volume or higher (hereinafter referred to as a snoring state) or in at least one of the apnea states.

The vibrator 56 is provided in the vicinity of the hinge portion 60 in the accommodation space Q. In this embodiment, an example is shown in which the vibrator 56 is mounted on the end portion of the second substrate 50 on the hinge portion 60 side. The second substrate 50 is fitted and fixed to the partition wall 44. The partition wall 44 is fitted and fixed to the inner case 42. Then, a screw hole 45 (see FIG. 6) is formed so as to penetrate the partition wall 44 from the bottom plate of the inner case 42. The inner case 42, the partition wall 44, and the outer case 43 are screwed and fixed by screws 46 (see FIG. 6) inserted into the screw holes 45. That is, the vibrator 56 is configured so that the vibration is transmitted to the accommodating case 41 through the second substrate 50 and the partition wall 44. Since at least a part of the abutting portion 70 abuts on the accommodating case 41, the vibration transmitted to the accommodating case 41 is also transmitted to the abutting portion 70.

Further, the vibration of the vibrator 56 is also transmitted through the transmission route transmitted to the mounting portion 30 through the hinge portion 60. As a result, the vibration of the vibrator 56 is transmitted to the neck Pn from both the measuring unit 40 (including the contacting unit 70) and the mounting unit 30. Here, as shown in FIG. 6, by arranging the vibrator 56 in the vicinity of the hinge portion 60, the vibration of the vibrator 56 can be easily transmitted to the mounting portion 30. Thereby, the single vibrator 56 can suitably give vibration to the subject from a plurality of points in the circumferential direction of the neck Pn.

-Other configurations-
A dustproof wall for preventing foreign matter (hereinafter, simply referred to as foreign matter) such as sweat (including moisture), dust, and dust of the subject from entering between the abutting portion 70 and the first opening 42a of the inner case 42. Is not provided. This makes it possible to increase the mobility of the contact portion 70. On the other hand, when the contact portion 70 is pushed into the accommodation space Q, foreign matter that has entered through the gap between the contact portion 70 and the first opening 42a of the inner case 42 does not enter the second substrate 50 or the battery 51. As described above, the accommodation space Q is provided with a partition wall 44a that partitions the first opening 42a from electronic components such as the second substrate 50 and the battery 51.

As shown in FIG. 9, the partition wall 44 is provided in the accommodation space Q at an intermediate position between the inner case 42 and the outer case 43 so as to separate the two cases. The partition wall 44 is fixed to the inner case 42 at the upper left corner portion 44c and the lower right corner portion 44d. Further, the partition wall 44 is configured to be fitted with the second substrate at the fitting portion 44e. The fitting portion 44e is composed of, for example, a translucent member in order to display the light of the light emitting diode mounted on the second substrate 50 on the side plate of the measuring portion 40. In this way, the partition wall 44 acts to be immobile at the fitting portion 44e of the inner case 42 during operation of the vibrator 56, so that the vibration is propagated from the vibrator 56 to the inner case 42 without being attenuated.

The power button 57 has, for example, a configuration in which a push button protrudes to the outside of the side plate of the measuring unit 40 so that the subject P can turn on / off the power of the breath sound measuring device 1.

The monitor lamp 58 is composed of, for example, a light emitting diode. By observing the light emitting state of the monitor lamp 58 through the fitting portion 44e, the subject P can confirm the power on / off state, the communication state, the charging state, and the like of the breath sound measuring device 1.

In the above embodiment, the mounting unit 30 and the measuring unit 40 are connected by a hinge unit 60, but the present invention is not limited to this.
