Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a neckband-type respiratory sound measuring device for measuring the sleep state of a subject.

Snoring during sleep may cause annoyance to people around you, and snoring may lead to sleep apnea, which may lead to obstructive apnea syndrome. Therefore, there is a demand for a breath sound measuring device that measures the sleep state of a subject and gives a stimulus to the subject in order to change the posture of the subject when snoring or sleep apnea occurs.

US Pat. No. 5,400,001 shows a method of attaching a microphone around each patient's neck to record sounds received by the microphone while the patient is asleep.

JP 2007-202939 A

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

For example, in the case of general men, the size of the neck circumference is about 36 to 47 cm, and some men have sizes outside the general size. Therefore, several size lineups (for example, S, M, L, etc.) are provided for neckbands. However, even among subjects using neckbands of the same size range, there are various neck shapes and neck circumference dimensions, and with general-purpose products, there is the problem that accurate size adjustment for each subject is difficult. In particular, during sleep, the subject may feel a sense of discomfort, which may interfere with comfortable sleep. In addition, there are cases in which the subject sleeps on their side, and if one side of the subject's neck is pressed against the bedding, the other side may rise, hindering accurate measurement.

That is, the present invention has been made in view of such a point, and is a neckband-type respiratory sound measuring device that can preferably acquire breath sounds from the neck of the subject while alleviating discomfort when the subject wears the device. intended to provide

A sleep state measuring device according to a first aspect of the present invention includes a measurement unit that acquires the subject's breath sounds by bringing the abutment part into contact with the skin of the anterior neck of the subject , and and a hinge connecting the proximal end of the measuring section and the proximal end of the mounting section. A rotating shaft part that supports the measurement part and the mounting part so as to be rotatable in the circumferential direction, and the measurement part and the mounting part that are closed so as to sandwich the neck of the subject from the outside when worn on the neck of the subject. and an urging portion that urges in a direction .

According to this aspect, since the abutting part is brought into contact with the skin of the anterior neck of the subject to acquire the breath sounds, the breath sounds can be preferably acquired from the neck of the subject. On the other hand, the other end of the mounting portion is brought into contact with the rear side portion opposite to the front side portion. That is, the attachment part is not extended to the front side of the subject. This makes it possible to alleviate the tightness of the subject's neck. In addition, when the subject sleeps sideways so that the contact portion faces upward, the applied portion can be prevented from being caught 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 due to the attachment portion being pushed by the bedding. In addition, it is possible to prevent the wearing part from rubbing against bedding or the like while sleeping.

Furthermore, the measuring section and the mounting section are connected by a hinge section. As a result, compared to the case of using an integrated neckband, it is possible to adjust the contact pressure to be suitable for subjects with different cervical (neck) sizes, and to minimize discomfort during wearing. can be reduced.

In a second aspect of the present invention, in the above first aspect, the contact portion is retractable with respect to the inner surface of the measurement portion and is biased in a projecting direction, and when attached to the neck of the subject, It may be arranged such that it is displaced in accordance with the shape of the subject's anterior neck and comes into contact with the anterior neck of the subject.

As a result, the adhesion of the abutting portion to the skin of the subject's anterior neck region is enhanced, the subject's feeling of wearing is improved, and the subject's skin is less likely to be bitten.

ADVANTAGE OF THE INVENTION According to this invention, a breath sound can be suitably acquired from a test subject's neck, reducing the discomfort at the time of a test subject's wearing.

It is for measuring sounds (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 neck of the subject. The breath sound measurement device 1 is an example of a sleep state measurement device that measures the sleep state of the subject P. As shown in FIG.

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

In the following description, the up-down direction and the left-right direction are defined with reference to the wearing state of the respiratory sound measuring device 1 of the subject P. FIG. In addition, the front (chest) side of the subject P is defined as front, and the back side is defined as rear. In addition, the “subject side” is defined based on the wearing state of the respiratory sound measuring device 1, and when describing the wearing unit 30, the measurement unit 40, etc., the subject side is defined as “inside” and the opposite side is defined as “outside”. may explain. In addition, the surface of the respiratory sound measuring device 1 on the side of the subject's neck Pn is referred to as the "inner surface 10a of the respiratory sound measuring apparatus 1" or simply the "inner surface 10a". That is, the “inner surface 10 a of the respiratory sound measuring device 1 ” is a concept that includes the inner surface 42 c of the measurement unit 40 in addition to the inner surface of the mounting unit 30 .

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

In the wearing state of the subject P shown in FIG. It is designed to be pressed against Pr1. On the other hand, as shown in FIG. 8 , when the contact portion 70 is in contact with the skin of the left front neck Pf2 of the subject P while the subject P is wearing the attachment portion 30, the pressing portion 32 is pressed against the subject P. It abuts on the right rear neck Pr2. In other words, the measuring section 40 and the pressing section 32a are arranged asymmetrically with respect to the left-right center of the neck Pn. The left-right center is defined by the center position of the throat when viewed from the front of the subject P, for example.

Here, the anterior neck Pf is a surface around the subject's neck Pn that is anterior to an imaginary plane passing through the centers of both ears of the subject P, or is an anterior to the front-rear center of the neck Pn. shall point to In particular, the contact position of the contact portion 70 is preferably the skin in the vicinity of the trachea (for example, the throat) in the anterior neck Pf, and the contact position of the contact portion 70 is the front part of the anterior neck Pf. position. In addition, the posterior neck Pr is a surface behind the imaginary plane passing through the centers of both ears of the subject P around the neck Pn of the subject, or a surface behind the front and back center of the neck Pn. shall refer to The pressing part 32 is pressed against the skin of the posterior neck Pr. That is, the pressing part 32 is pressed against the skin behind the subject P's ear. 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-shaped configuration in which the open ends are positioned in front of both ears of the subject P). and both open ends are pressed against the skin of the subject P on the front side of both ears), it is possible to alleviate discomfort (for example, feeling of tightness) of the subject P. In addition, since large blood vessels run in the vertical direction inside the ears of the neck, it is possible to prevent blood flow from being obstructed, compared to the case where the ears are pressed from both sides. From this point of view as well, the subject's P discomfort (for example, feeling of tightness) is alleviated.

(1) The subject P can spread both open ends of the respiratory sound measuring device 1 with both hands and wear it from the back side of the neck Pn toward the neck Pn, and (2) It has an elastic force for pinching the neck Pn from the outside in the circumferential direction so that at least a part of the inner surface 10a of the respiratory sound measuring device 1 is in close contact with the neck Pn when the subject P releases the hand, and (3 ) preferably have a strength that can withstand continuous use. As long as the above conditions (1) to (3) are satisfied, the specific structure and constituent materials of the mounting portion 30 are not particularly limited. For example, an elastic structure in which an elastomer resin surrounds a leaf spring 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 elastomer resin or polypropylene resin.

《Hinges》
The hinge portion 60 supports the mounting portion 30 and the measuring portion 40 so as to be rotatable between the unfolded position indicated by the solid line in FIG. 3 and the folded position indicated by the phantom line in FIG.

The deployed position is a position where the measuring section 40 is opened to the maximum outward, and the inner surface 10a is substantially flat at the joint between the two. That is, when the measurement unit 40 is in the deployed position, the respiratory sound measurement device 1 as a whole is configured to form an arc-shaped body. At the unfolded position, for example, the distal end portion of the mounting portion 30 and the proximal end portion of the measuring portion 40 are brought into contact with each other, and are locked so that the angle between the mounting portion 30 and the measuring portion 40 does not widen further outward. be done.

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

A movable range R11 between the unfolded position and the folded position is not particularly limited, but is, for example, about 40 degrees. With a rotation range of about 40 degrees, subjects P with a wide range of body types can be accommodated. However, the movable range (rotational range) is not limited to about 40 degrees, and for example, the movable range may be less than 40 degrees or greater than 40 degrees. The degree of opening of the respiratory sound measuring device 1 changes due to the rotation between the unfolded position and the folded position.

As shown in FIG. 6, the hinge portion 60 includes a rotating shaft portion 61 forming a rotating shaft AX, which is the central axis of the rotating operation, and an urging force that urges the measuring portion 40 toward the bending position. means 62;

It can be realized by

Although the configuration of the biasing means 62 is not particularly limited, here, an example using a torsion coil spring is shown. The biasing means 62 has one end fixed to the housing case 41 and the other end fixed to the mounting portion 30 . Although not shown, a so-called hinge spring in which a hinge and a spring are integrated may be used as the hinge portion 60 . Also in this case, the hinge spring is fixed to each of the housing case 41 and the mounting portion 30 .

Here, the biasing force of the biasing means 62 is configured to be greater than the biasing force of the compression coil spring 78 . By adopting such a configuration, (1) the general positioning according to the subject's body shape (especially the size of the neck) is performed by the action of the biasing means 62, and (2) the action of the compression coil spring 78 is performed. , the operation of adjusting the angle of the contact surface 70b of the contact part 70 so as to follow the measurement location (skin surface) of the breath sound of the subject's neck Pn can be more preferably realized. Here, a partition wall 44b may be provided in the housing space Q on the base end side of the measuring section 40 to prevent foreign matter from entering around the hinge section 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 may be provided in which a partition wall 44a and a partition wall 44b, which will be described later, are integrally formed. By adopting such a configuration, it is possible to reduce the number of constituent members and improve the workability of the assembly work. In FIG. 9, the partition wall 44 is hatched upward to the right.

《Measuring part》
-Accommodation case-
As shown in FIGS. 5 and 6, the measurement unit 40 has a housing case 41 in which a housing space Q is formed by fitting an inner case 42 and an outer case 43 together.

The inner case 42 has a rounded bottom plate that protrudes outward, and side plates rising outward from the upper and lower ends and tips of the bottom plate so as to surround the housing space Q. - 特許庁In the bottom plate of the inner case 42, a circular first opening 42a is formed at approximately the vertical center on the tip side, and a rectangular second opening 42b is formed at approximately the circumferential and vertical center. .

The contact portion 70 is inserted from the inside of the housing case 41 into the first opening portion 42a. The contact portion 70 is retained in the storage case 41 by a flange portion 70c (see FIG. 6) formed at the base end portion. The second opening 42b is a measurement window through which measurement light passes, for example, when the optical human detection sensor 59 is used to detect whether the respiratory sound measurement device 1 is worn on the neck Pn. used as The second opening 42b is not necessarily required, and is unnecessary, for example, when the human detection sensor 59 is of a type other than the optical type or when the human detection sensor 59 itself is not provided.

As shown in FIG. 9, the base end portions (the end portions on the mounting portion 30 side) of both side walls of the inner case 42 are provided to rotatably support the rotation shaft portions 61 of the hinge portion 60, which will be described later. of bearings 42e are provided. Although the structure of the bearing 42 e is not particularly limited, for example, a shaft insertion hole slightly larger than the outer shape of the rotating shaft portion 61 is formed in the base end portion 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 includes an upper plate arranged to face the bottom plate of the inner case 42, and upper and lower ends of the upper plate so as to surround the accommodation space Q described above. 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 partially cover the hinge portion. After aligning the inner case 42 and the outer case 43, the housing case 41 is screwed with screws 46 (see FIG. 6) inserted into screw holes 45 (see FIG. 6) formed in the bottom plate of the inner case 42. Fixed.

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

Although not shown, the side plate of the measurement unit 40 is provided with an insertion opening that opens outward, and a communication/charging cable can be inserted into the connector 55 through the insertion opening. It's becoming

-Abutment part-
As shown in FIGS. 2 and 6, the respiratory sound measuring device 1 includes a contact portion 70 that protrudes inward (toward the neck Pn of the subject P) from the inner surface 42c of the inner case 42. . A sound guide opening 70a for introducing the breath sound 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 opening 70a. The contact surface 70b contacts the neck Pn when the respiratory sound measuring device 1 is worn. Thus, by providing the contact surface 71a on the protruding portion 70, the contact area with the neck Pn can be increased, preventing the breathing sound from leaking to the outside and enhancing the sound collection effect. 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 has a substantially rectangular recess in the central portion, into which a rectangular first substrate 73 is fitted. 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 as a concept that includes a wide range of devices, devices, and circuits that convert sound waves into electrical signals, and sound sensors such as MEMS microphones used in such devices. Its specific configuration is not particularly limited. On the other hand, in this 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 forming 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 guiding space RS2, which will be described later. For example, plastic resin (for example, polyoxymethylene) can be used as the material forming the contact portion 70 . Also, 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 conducting space RS for guiding breathing sound introduced from the sound conducting port 70 a to the microphone 74 . The sound-guiding space RS includes a first sound-guiding space RS1, a second sound-guiding space RS2, and a third sound-guiding space RS3. The first sound guide space RS1 is a space formed by a sound guide hole 73a penetrating in the front and back direction at a position corresponding to the microphone 74 of the first substrate 73. As shown in FIG. The sound guide opening 70a is formed with a tapered sound collector 70e (see FIG. 2) whose inner diameter gradually narrows toward the microphone 74. The space inside this sound collector 70e is called a third sound guide space RS3 (see FIG. 2). 6). 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 against 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 vibrations caused by an impact or the like given from the outside to the respiratory sound measuring apparatus 1, and the generation of solid-borne sound in the sound conducting space RS. . Vibration of the respiratory sound measuring device 1 is caused by, for example, rubbing of the respiratory sound measuring device 1 with bedding or the subject's hand when the subject P changes his or her posture while sleeping.

Although the material forming the sound insulating material 77 is not particularly limited, it absorbs solid vibrations from the wearing part 30 and hardly absorbs the sound waves of respiratory sound acquired from the neck Pn and passing through the second sound guiding space RS2. It is preferably made of a material such as An elastic material such as silicone rubber can be preferably used for the sound insulating material 77 .

A cover 75 that covers the first substrate 73 is attached to the proximal 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 respiratory 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 is pressed. The amount of protrusion of the contact portion 70 from . Furthermore, due to the action of the compression coil spring 78, the contact surface 70b is in close contact with the skin of the neck Pn. As a result, the tightness of the subject's neck Pn to the skin is enhanced, and the subject's P wearing comfort is improved, and the subject's P's skin is less likely to be bitten.

FIG. 10 shows an example of a subject whose neck is thinner than that in FIG. In the example of FIG. 10, if the measurement unit 40 remains in the deployed position when the respiratory sound measurement device 1 is worn, the contact surface 70b of the contact unit 70 does not contact the neck Pn (see the virtual line in FIG. 10). . In this embodiment, the hinge portion 60 is biased toward the bending position, so the measurement portion 40 rotates toward the subject's neck Pn side (inward). FIG. 10 shows an example of rotation by a rotation angle of R12 (R11>R12). In addition, the inner surface 42c of the measuring section 40 near the neck Pn also tilts inward by the measuring section 40 entering the neck Pn side. In this embodiment, the angle of the contact surface 70b of the contact portion 70 changes according to the force that the contact surface 70b receives from the neck Pn (see R22 in FIG. 10). That is, the angle of the contact surface 70b of the contact portion 70 changes along the neck Pn. In addition, since the biasing force of the compression coil spring 78 acts on the contact portion 70, it is possible to enhance the adhesion of the contact surface 70b to the subject's neck Pn.

FIG. 11 shows an example of a subject with a thicker neck than in FIG. In the example of FIG. 11, the neck Pn does not fit inside the wearing part 30, but as described above, the respiratory sound measuring device 1 does not open beyond the deployment position. The external size of the is expanded. Further, most of the contact portion 70 enters the accommodation space Q, and the amount of protrusion of the contact portion 70 from the measuring portion 40 is extremely small. Such an operation prevents the contact portion 70 from biting into the subject's neck Pn. Also in this case, the urging force of the compression coil spring 78 works to enhance the adhesion of the contact surface 70b to the subject's neck Pn.

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 substrate-
Returning to FIG. 6, the second substrate 50 is arranged on the bottom plate (subject-side plate) of the inner case 42 so as to extend along the longitudinal direction of the measuring section 40 (the circumferential direction of the mounting section 30). The second board 50 is fixed to the housing 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 (not shown) for storing measurement results, a communication module 53 for transmitting measurement results to an external device (for example, terminal device 80), body position / Acceleration sensor 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 the subject (see FIG. 2), a human detection sensor 59, and the like are mounted. The control unit controls the operation of the respiratory 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 supply 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 controller. The vibrator 56 is controlled to vibrate, for example, when the subject P is snoring at a predetermined volume or more (hereinafter referred to as a snoring state) or when the subject P is apnea.

The vibrator 56 is provided near the hinge portion 60 within the housing space Q. As shown in FIG. This embodiment shows an example in which the vibrator 56 is mounted on the end portion of the second substrate 50 on the side of the hinge portion 60 . 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 . A screw hole 45 (see FIG. 6) is formed so as to extend from the bottom plate of the inner case 42 through the partition wall 44 . 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 such that vibration is transmitted to the housing case 41 through the second substrate 50 and the partition wall 44 . At least a portion of the contact portion 70 contacts the housing case 41 , so the vibration transmitted to the housing case 41 is also transmitted to the contact portion 70 .

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

-Other configurations-
Between the contact portion 70 and the first opening 42a of the inner case 42, there is a dust-proof wall for preventing foreign matter such as perspiration (including moisture), dust, and dust (hereinafter simply referred to as foreign matter) from entering. is not provided. Thereby, the mobility of the contact part 70 can be improved. On the other hand, when the contact portion 70 is pushed into the housing space Q, foreign matter entering 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. Thus, the accommodation space Q is provided with a partition wall 44a that partitions the first opening 42a and electronic components such as the second substrate 50 and the battery 51 from each other.

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

The power button 57 is, for example, configured such that a push button protrudes outside the side plate of the measuring unit 40 so that the subject P can turn on/off the power of the respiratory sound measuring device 1 .

The monitor lamp 58 is composed of, for example, a light emitting diode. The subject P can check the power ON/OFF state, communication state, charging state, etc. of the respiratory sound measuring device 1 by looking at the light emitting state of the monitor lamp 58 through the fitting portion 44e.

In addition, in the above-described embodiment, the mounting section 30 and the measurement section 40 are connected by the hinge section 60, but the present invention is not limited to this. Although not shown, for example, the hinge portion 60 may be omitted from the respiratory sound measuring device 1 of the above embodiment, and the mounting portion 30 and the measuring portion 40 may be integrally connected. In that case, the respiratory sound measuring device 1 has a shape corresponding to the unfolded state of the above embodiment.
