Description

Wearable sensing device and diagnostic device using the same {WEARABLE SENSING DEVICE AND DIAGNOSTIC DEVICE USING THE SAME}

The present invention relates to a wearable sensing device, and more specifically, to measure the breathing rate of a subject through a sensing value that changes through the tension of the strap according to the subject's breathing, and through heartbeat sounds amplified through a diaphragm. It relates to a wearable sensing device capable of measuring the heart rate of a subject and a diagnostic device using the same.

Recently, as interest in health has increased, research on healthcare using electronic devices has been actively conducted. For example, sensors mounted on electronic devices can collect information related to the electronic device, the outside of the electronic device, or the user, and it is most important for the user to continuously measure biosignals in order to check his or her condition. do. In this regard, as technology that allows monitoring the user's exercise state or abnormal condition is required, electronic devices that provide the function of checking the user's biological signals are being developed.

In particular, among the biosignals collected from users, the respiratory rate is one of the vital signs that determine the most basic level of vitality of the body, and various methods are used to measure the respiratory rate, that is, the number of breaths per minute.

For example, there are two types of methods for measuring the breathing rate or respiratory rate of a subject: spirometry and capnometry.

Spirometry is a method of measuring the flow of air entering and leaving the lungs using a spirometer, and capnometry is a method of measuring CO2 according to respiration. This conventional method has relatively high accuracy, but has limitations in that it requires additional equipment and makes continuous monitoring difficult.

Heart sounds are the sounds that occur when the heart contracts and expands. Heart sounds can generally be confirmed through an auscultation sensor, but when confirmed through an auscultation sensor, other noises are picked up together, so a filter must exist to remove noise.

In addition, when multiple devices are built into the stethoscope, the internal structure of the stethoscope becomes complicated, which is disadvantageous in terms of maintenance due to frequent breakdowns.

In addition, animals such as dogs (including puppies), cats, and birds may experience changes in their breathing and heart rate depending on the external temperature even if they do not display abnormal symptoms, so an increase in the subject's breathing or heart rate may cause abnormal conditions (e.g. For example, it is important to determine whether it is caused by disease) or external temperature. However, since conventional measuring devices do not consider external temperature at all, if the respiratory rate or heart rate increases due to the influence of temperature in an environment where the external temperature of the subject is hotter than the standard value or colder than the standard value, even though the subject is in a normal state, And an error may occur in judging it as an abnormal condition.

FIGS. 2 and 3 are exploded perspective views of the sensing device 10 illustrated in FIG. 1 , and FIG. 4 is a cross-sectional view of the sensing device 10 illustrated in FIG. 1 .

The main housing 100 is a case that forms the external shape of the sensing device 10, and may be formed in a square shape, circular shape, or other shape. The main housing 100 is worn on the subject's body through a strap (S).

The main housing 100 has an open top, and the open top is closed by a cover (C). The cover C can be selectively fastened or released from the main housing 100. The method of fastening the cover (C) and the main housing (100) is not limited to any one method.

A circuit board 110 is mounted inside the main housing 100. The circuit board 110 is disposed on the bottom plate 103 of the main housing 100. The circuit board 110 is configured with an electric circuit so that the strain sensor 133, battery (B), expansion ECG module 161, stethoscope sensor 113, etc. are connected.

The battery B may be placed on top of the circuit board 110. The battery B can be supplied with power through wired charging or wireless charging, and when supplied with power through wireless charging, the circuit board 110 may be further equipped with a wireless charging module (not shown). When the battery B is charged by wire, a charging hole 102 through which the charging cable passes may be formed on one side of the main housing 100. The charging cable passes through the charging hole 102 and is connected to the charging terminal 112 formed on the circuit board 110.

On one side of the main housing 100, a mounting groove 101 is formed that is open in the direction of the cover C of the main housing 100 (i.e., upward direction). The mounting groove 101 is a groove for mounting the first fastening member 130 to the main housing.

The main housing 100 is provided with a first fastening member 130 and a second fastening member 120.

The first fastening member 130 is mounted through the mounting groove 101 formed on one side of the main body housing 100.

The first fastening member 130 includes an elastic body 131 and a fastening ring 132.

The elastic body 131 is formed in the form of an elastic plate. The elastic body 131 is disposed on the inner surface of the main body housing 100 where the mounting groove 101 is formed. One side of the elastic body 131 is disposed at a position corresponding to the mounting groove 101 of the main body housing 100. The elastic body 131 is located on the inner surface of the main body housing 100 on the other side opposite to the mounting groove 101.

One end of the fastening ring 132 is coupled to the elastic body 131 at a position corresponding to the mounting groove 101 of the main body housing 100. When the elastic body 131 is disposed on the inner surface of the main body housing 100, the other end of the fastening ring 132 penetrates the mounting groove 101 and touches the outer surface of the main body housing 100 opposite to the mounting groove 101. extends towards.

The side of the main housing 100 is located at a spaced apart area between the other end of the fastening ring 132 and the elastic body 131.

The first fastening member 130 may be mounted on one side of the main body housing 100 while the fastening ring 132 is inserted into the mounting groove 101 of the main body housing 100. In this state, the end of the strap (S) is hung on the fastening ring 132.

A strain sensor 133 is attached to the elastic body 131. The strain sensor 133 may be attached to a side of the elastic body 131 opposite to the side to which the fastening ring 132 is connected.

The strain sensor 133 measures the change in shape of the first fastening member 130 or the attachment point of the first fastening member 130 caused by tension of the strap S according to the subject's breathing.

For example, when a subject breathes, the rib cage repeatedly contracts and expands. When the chest of the subject expands, a tensile force is generated in the strap (S), and the fastening ring 132 of the first fastening member 130 is pulled by the tensile force of the strap (S). When the fastening ring 132 is pulled, a shape change occurs in the elastic body 131 or the elastic body 131 of the first fastening member 130, and the strain sensor 133 is connected to the elastic body 131 or the elastic body ( 131), the shape change is measured and transmitted to the circuit board 110.

A fixing member 106 into which the end of the elastic body 131 of the first fastening member 130 (that is, the opposite side of the fastening ring 132) is inserted may be further formed inside the main body housing 100. The end of the elastic body 131 of the first fastening member 130 is inserted into the fixing member 106 to fix its position inside the main body housing 100.

The second fastening member 120 is formed on the side of the main housing 100 facing the first fastening member 130.

The second fastening member 120 may be formed in a ring shape. Both ends of the second fastening member 120 are connected to the sides of the main housing 100. The strap S may be fastened between the second fastening member 120 and the side of the main body housing 100. For reference, either end of the second fastening member 120 may be spaced apart from the side of the main body 100 at a predetermined distance.

For reference, the second fastening member 120 may be formed in the same shape as the first fastening member 130 and may be mounted using a mounting method. At this time, a groove (not shown) identical to the mounting groove 101 on the side where the first fastening member 130 is mounted may be formed on the side of the main body housing 100 where the second fastening member 120 is mounted. Additionally, a fixing member 106 may be formed on the inner side of the main body 100 where the second fastening member 120 is mounted.

A bottom plate 103 is provided at the lower part of the main housing 100.

A first sensing hole 105 is formed in a portion of the bottom plate 103. The first sensing hole 105 formed in the bottom plate 103 is located on the outside of the bottom plate 103 (diaphragm 140 side) and the inside of the main housing 100 (circuit board ( Connect to page 110).

A fastening protrusion 104 for fastening the diaphragm 140 is formed around the outer side of the bottom plate 103 (i.e., the side facing the subject). The end of the fastening protrusion 104 may be bent toward the side of the main housing 100 in order to easily fasten the diaphragm 140. A pressure hole (not shown) for placing the diaphragm 140 is formed on the lower surface of the main housing 100 by the fastening protrusion 104.

The diaphragm 140 is mounted on the fastening protrusion 104 to cover the entire bottom plate 103 of the main housing 100. At this time, the diaphragm 140 is mounted at a predetermined distance from the bottom plate 103 of the main body housing 100. In this way, when the diaphragm 140 is mounted to be spaced apart from the bottom plate 103 of the main body housing 100 at a predetermined interval, there is a transition space between the bottom plate 103 of the main body housing 100 and the diaphragm 140. (R) (transient space) is formed.

When the sensing device 10 is worn on a subject, the diaphragm 140 formed on the sensing device 10 comes into contact with the chest of the subject, and at this time, the heartbeat sound of the subject transmitted by deformation of the diaphragm 140 is It is amplified as it passes through the transition space (R) between the diaphragm 140 and the bottom plate 103. The degree of amplification of the subject's heartbeat sound transmitted by deformation of the diaphragm 140 may vary depending on the shape or size of the transition space R.

The amplified heartbeat sound is input to the auscultation sensor 113 provided on the circuit board 110 through the first sensing hole 105. For reference, the auscultation sensor 113 is provided at a position corresponding to the first sensing hole 105 on the circuit board 110. In addition, a transition hole (not shown) connecting the first sensing hole 105 and the auscultation sensor 113 may be further formed in the circuit board 110. The transition hole may be formed with the same diameter or a smaller diameter than the first sensing hole 105.

The diaphragm 140 may be formed in a shape and material that further amplifies the wavelength region representing the heartbeat of the subject. For example, the diaphragm 140 may have a surface in contact with the subject in the form of a flexible plate.

Additionally, the diaphragm 140 is formed in the form of a thin rubber film and may be formed in the shape of a convex lens or a dome that is convex toward the subject.

A sealing pad 150 may be further provided between the bottom plate 103 of the main housing 100 and the circuit board 110.

The sealing pad 150 is in close contact with the bottom plate 103 and the circuit board 110 of the main housing 100 to prevent heartbeat sounds from leaking out.

The sealing pad 150 has a second sensing hole 151 with a smaller diameter than the first sensing hole 105 formed in the bottom plate 103 of the main body housing 100 at a position corresponding to the first sensing hole 105. is formed For reference, if a transition hole is formed in the circuit board 110, the transition hole may be formed to have the same diameter or a smaller diameter than the second sensing hole 151.

The sensing device 10 is capable of amplifying only sounds of a desired wavelength by adjusting the diameters of the first sensing hole 105 and the second sensing hole 151. For example, since the auscultation sensor 113 measures even the smallest sounds, noise is also measured in addition to the subject's heartbeat. By adjusting the diameters of the first sensing hole 105 and the second sensing hole 151, the desired wavelength is adjusted. If only the sound is amplified, only the desired sound (i.e. heartbeat sound) can be measured through the auscultation sensor 113.

The extended ECG module 161 (electrocardiogram) is selectively connected to the sensing device 10. The extended ECG module 161 is attached to the subject's body, that is, the arm, leg, or abdomen of the subject, and records the action current according to heart contraction as a curve.

The expansion ECG module 161 may be connected to an interface circuit (not shown) provided on the circuit board 110 through an expansion cable 161. At this time, the extension cable 161 is connected to the external connection terminal 111 connected to the interface circuit (not shown). If the expansion ECG module 161 is wirelessly connected to the interface circuit, an external connection terminal may not be provided.

The expansion ECG module 161 may be equipped with one or more electrocardiogram sensors, and even when there are two or more electrocardiogram sensors, it can be connected to the interface circuit provided on the first circuit board 110 through one expansion cable 161. .

Figure 5 is a perspective view illustrating a method of attaching and detaching the first fastening member 130 illustrated in Figure 1.

As shown in FIG. 5, the first fastening member 130 can be detached from the main housing 100 after the cover C is detached from the main housing 100.

When the fastening ring 132 is moved upward in the direction of the arrow of the mounting groove 101 and the end of the elastic body 131 of the first fastening member 130 is moved upward in the arrow direction of the fixing member 106, the first fastening member 130 The fastening member 130 is detached from the main housing 100. In this way, the first fastening member 130 can be easily detached from the main housing 100, making it easy to replace the strain sensor 133 according to its lifespan.

Figure 6 is a diagram showing the change in shape of the first fastening member 130.

As shown in Figure 6, when the subject breathes and the rib cage expands, a tensile force in the direction of the arrow is generated in the strap (S). At this time, the fastening ring 132 is pulled by the strap (S), and the elastic body 131 is pulled with the end of the elastic body 131 of the first fastening member 130 fixed to the fixing member 106. It gets bent. The strain sensor 133 measures the displacement value for the change in shape of the bent elastic body 131. When the subject breathes and the rib cage contracts, the elastic body 131 is restored to its original state.

Figure 7 is a perspective view showing a modified example of the first fastening member 130 of Example 1.

As shown in FIG. 7, the elastic body 134 of the first fastening members 134 and 137 includes a first partition wall portion 135 and a second partition wall portion 136.

The first partition wall portion 135 is a portion to which the fastening ring 132 is connected. The thickness of the first partition wall 135 is relatively thinner than the thickness of the second partition wall part 136.

A strain sensor (not shown) is attached to the inner surface of the first partition 135.

The second partition 136 is a part that is inserted into a fixing member (not shown) of the main body housing (not shown). The second partition wall part 136 is formed to be relatively thicker than the first partition wall part 135.

When a tensile force is generated in a strap (not shown), a change in the shape of the first partition 135, which has a relatively thin thickness, occurs, and the strain sensor measures the amount of displacement of the first partition 135.

Figure 8 is an exploded perspective view showing a modified example of the first fastening member 170 of Example 1, and Figure 9 is a perspective view showing the strain sensor 174 mounted on the first fastening member 170.

Referring to FIG. 8, mounting grooves 108 are formed at both ends of the side 107 of the main body 100 where the first fastening member 170 is formed. The upper part of the mounting groove 108 is open so that the first fastening member 170 can be unlocked in the open direction.

The first fastening member 170 includes a strap fastening plate 171, a sensor fastening part 172, and a sensor fitting groove 173.

The strap fastening plate 171 is a part where the strap is hung.

Both ends of the strap fastening plate 171 are disposed to correspond to the mounting grooves 108 formed at both ends of the main body housing 100. For example, the length of the strap fastening plate 171 may be greater than the length connecting the mounting grooves 108 formed at both ends of the main body housing 100.

The sensor fastening portion 172 protrudes toward the inside of the main body housing 100 from the inner surface 107 of the strap fastening plate 171 corresponding to the mounting grooves 108 formed at both ends of the main body housing 100. is formed

The end of the sensor fastening part 172 is bent into a 'ㄷ' shape. The open part of the 'ㄷ' shape of the sensor fastening part 172 faces onto the other sensor fastening part 172. Hereinafter, the open part of the ‘ㄷ’ shape of the sensor fastening part 172 will be defined and explained as the sensor fitting groove 173.

The end of the strain sensor 174 is inserted into the sensor fitting groove 173. For example, when the strain sensor 174 is inserted into the sensor fitting groove 173, the strain sensor 174 is disposed at a predetermined distance from the inner surface 107 of the main body housing 100.

A protrusion 109 is formed on a portion of the inside of the side 107 of the main housing 100. The protrusion 109 is in contact with the strain sensor 174 mounted on the first fastening member 170. Two or more protrusions 109 may be formed, but it may be desirable to form one at a location corresponding to the center of the strain sensor 174.

FIG. 10 is a diagram showing the operation of the first fastening member 170 illustrated in FIGS. 8 and 9.

When the subject's rib cage expands while breathing, a tensile force (in the direction of the arrow) is generated in the strap.

At this time, the strap fastening plate 171 of the first fastening member 170 is pulled in the direction of the tensile force of the strap and presses the strain sensor 174 to the inner surface 107 of the main body housing 100. The strain sensor 174 is pulled to the inner surface 107 of the main housing 100 by the strap and comes into contact with the protrusion 109, thereby receiving pressure at a position corresponding to the protrusion 109.

The pressure value measured by the strain sensor 174 is used to measure the subject's respiration.

FIG. 11 is a block diagram showing the communication circuit 11 and external device 12 of the sensing device 10 shown in FIG. 1.

As shown in FIGS. 3 and 11 , the sensing device 10 may further include a communication circuit 11.

The communication circuit 11 is provided on the circuit board 110.

The communication circuit 11 transmits the measurement signal from the strain sensor 133 and the measurement signal from the auscultation sensor to the external device 12. Here, the external device 12 may mean a diagnostic device (not shown) or an analysis device (not shown). The diagnostic device or analysis device receives at least one waveform signal of a heart rate waveform (measurement signal from the stethoscope sensor 113) and a respiration waveform (measurement signal from the strain sensor) from the sensing device 10, and detects the subject through the data. At least one of heart rate or respiratory rate can be calculated. Additionally, the diagnostic device or analysis device may determine the abnormal state of the subject through the subject's heart rate, respiration rate, or heart rate.

Meanwhile, the sensing device 10 may be further equipped with a temperature sensor (not shown).

The temperature sensor measures the external temperature of the sensing device 10. Here, the external temperature refers to the temperature of the laboratory where the subject is tested.

The communication circuit 11 provides the temperature measured by the temperature sensor to a diagnostic device or analysis device.

The diagnostic device or analysis device determines the abnormal state of the subject by comprehensively considering at least one of the subject's heart rate or respiratory rate and the external temperature measured by the temperature sensor.

For example, when at least one of the subject's heart rate or respiratory rate increases or decreases, the diagnostic device or analysis device determines whether it is due to an abnormal condition (eg, disease) or external temperature.

If at least one of the subject's heart rate or respiratory rate increases or decreases even though the external temperature is within the appropriate temperature range (room temperature), it is determined that an abnormal condition has occurred in the subject, and the external temperature is within the appropriate temperature range (room temperature). temperature), an increase or decrease in at least one of the subject's heart rate or respiratory rate is judged to be an increase or decrease due to the external temperature.

Here, the appropriate temperature range (room temperature) that does not significantly affect the determination of the subject's abnormal condition may be between 22 and 25°, and increases with each 1° increase or decrease in the temperature range. The respiratory rate or heart rate of the subject can be confirmed from an algorithm or a pre-built DB.

Figure 12 is a block diagram showing the configuration of a wearable sensing device 20 according to Embodiment 2 of the present invention.

The sensing device 20 of Embodiment 2 may be implemented in the same form as the sensing device 10 of Embodiment 1, and further includes a counting circuit 21 on a circuit board (not shown). All other components except the counting circuit 21 are the same as those of Embodiment 1, so duplicate descriptions are omitted.

The subject's breathing is divided into inspiration and exhalation.

During the inspiration process, the intercostal muscles contract and the ribs are lifted, and the diaphragm also contracts and goes down, increasing the volume of the thoracic cage. Conversely, during expiration, the intercostal muscles relax and the ribs go down, and the diaphragm also relaxes and goes up, reducing the volume of the thoracic cavity.

In the present invention, breathing can be defined in a broad sense to detect inspiration and exhalation. Or, in a narrower sense, it can mean the expansion and contraction of the ribcage, and in a narrower sense it can mean the expansion and contraction of the lungs. In other words, the definition of breathing in the present invention is interpreted to encompass not only inspiration and exhalation, but also expansion and contraction of the chest or lungs.

Here, when the subject breathes, the rib cage expands, and when the rib cage expands to its maximum level, this is the moment when breathing changes, that is, when it changes from inhalation to exhalation.

When the subject's rib cage expands during inspiration, a tensile force in the direction of the arrow is generated in the strap (S). At this time, the fastening ring is pulled by the strap, and the elastic body of the first fastening member is bent while the end of the elastic body is fixed to the fixing member. And when the subject's rib cage contracts during exhalation, the elastic body is restored to its original state.

The strain sensor measures the displacement value of the shape change of the bent elastic body.

The counting circuit 21 calculates the number of breaths per minute using the peak value and the next peak value of the respiration waveform measured by the strain sensor.

The heartbeat sound transmitted by deformation of the diaphragm is amplified as it passes through the transition space (R) (transient space) between the diaphragm and the bottom plate, and the amplified heartbeat sound is formed on the bottom plate of the lower case 700. 1 It is measured by the auscultation sensor 113 through the sensing hole.

The counting circuit 21 calculates the heart rate per minute using the peak value and the next peak value of the heart rate waveform measured by the auscultation sensor 113.

The communication circuit 22 transmits at least one of the breathing rate or the heart rate calculated by the counting circuit 21 to the external device 23. The external device 23 may be a diagnostic device or an analysis device, and the diagnostic device or analysis device may determine an abnormal state of the subject through the subject's heart rate, respiratory rate, or electrocardiogram.

Meanwhile, the sensing device 20 may be further equipped with a temperature sensor (not shown).

The temperature sensor measures the external temperature of the sensing device 20. Here, the external temperature refers to the temperature of the laboratory where the subject is tested.

The communication circuit 22 provides the external temperature measured by the temperature sensor to the external device 23 (i.e., a diagnostic device or analysis device).

The diagnostic device or analysis device determines the abnormal state of the subject by comprehensively considering at least one of the subject's heart rate or respiratory rate and the external temperature measured by the temperature sensor.

Figure 13 is a block diagram showing the configuration of a wearable sensing device 30 according to Embodiment 3 of the present invention.

The sensing device 30 of Embodiment 3 may be implemented in the same form as the sensing device 10 of Embodiment 1, and further includes a counting circuit 31 and a diagnostic circuit 33 on the circuit board. Except for the counting circuit 31 and the diagnostic circuit 33, all other components are the same as those of Embodiment 1, so redundant description will be omitted.

Additionally, since the counting circuit 31 is the same as that of Embodiment 2, redundant description will be omitted.

The diagnostic circuit 33 may determine the abnormal state of the subject through the subject's heart rate or respiratory rate measured by the counting circuit 31. For example, the diagnostic circuit 33 may determine that an abnormal state has occurred in the subject when at least one of the subject's heart rate or respiratory rate increases or decreases. Additionally, the diagnostic circuit 33 may determine that an abnormal condition has occurred if the subject's heart rate or breathing rate is irregular.

Meanwhile, the sensing device 30 may be further equipped with a temperature sensor (not shown).

The temperature sensor measures the external temperature of the sensing device 30. Here, the external temperature refers to the temperature of the laboratory where the test of the subject is performed.

The diagnostic circuit 33 determines the abnormal state of the subject by comprehensively considering at least one of the subject's heart rate or respiratory rate and the external temperature measured by the temperature sensor.

Figure 14 is a perspective view showing a wearable diagnostic device according to Example 4 of the present invention.

The diagnostic device 40 of Example 4 is a product of Example 1 in which sensor-related devices and circuits that measure breathing rate or heart rate through signals measured from the sensor are separated. Components related to the sensor are built into the sensing device 50, and circuits that measure breathing rate or heart rate are built into the computing device 60.

For example, when the subject is a small animal, the size of the sensing device 50 is limited. If a large sensing device 50 is used even though the animal is a small animal, measurement errors may occur. For example, in the case of small dog breeds, the chest is formed in a shape that protrudes sharply toward the front. If the sensing device 50 is formed large, it may not completely adhere to the chest of small dog breeds, resulting in measurement errors.

In Embodiment 4, it is possible to design the sensing device 10 to be smaller in size by embedding the sensor-related device in the sensing device 50 and separating the remaining components into the computing device 60.

FIG. 15 is a cross-sectional view of the sensing device 50 shown in FIG. 14.

The other end of the fastening ring 532 may be formed to be spaced apart from the elastic body 531. The side of the main body housing 500 is disposed at a spaced apart area between the other end of the fastening ring 532 and the elastic body 531.

The first fastening member 530 may be mounted on one side of the main body housing 500 while the fastening ring 532 is inserted into the mounting groove 501 of the main body housing 500. The end of the strap (S) is hung on the fastening ring 532.

A strain sensor 533 is attached to the elastic body 531. The strain sensor 533 may be attached to a side of the elastic body 531 opposite to the side to which the fastening ring 532 is connected.

The strain sensor 533 measures the change in shape of the first fastening member 530 or the attachment point of the first fastening member 530 caused by tension of the strap S according to the subject's breathing.

For example, when a subject breathes, the rib cage repeatedly contracts and expands. When the chest of the subject expands, a tensile force is generated in the strap (S), and the fastening ring 532 of the first fastening member 530 is pulled by the tensile force of the strap (S). When the fastening ring 532 is pulled, a shape change occurs in the elastic body 531 or the elastic body 531 of the first fastening member 530, and the strain sensor 533 is connected to the elastic body 531 or the elastic body ( The shape change is measured at 531 and transmitted to the circuit board 510.

The strap S may be fastened between the second fastening member 520 and the side of the main body housing 500. For reference, one of both ends of the second fastening member 520 may be formed to be spaced apart from the side of the main housing 500 at a predetermined distance.

For reference, the second fastening member 520 may be formed in the same shape as the first fastening member 530 and may be mounted using a mounting method. At this time, a groove (not shown) identical to the mounting groove 501 on the side where the first fastening member 530 is mounted may be formed on the side of the main body housing 500 where the second fastening member 520 is mounted.

A communication penetration hole through which the power communication line 41 passes is formed on the side of the main body housing 500 of the sensing device 50. The power communication line 41 is connected to the communication terminal of the first circuit board 510 through a communication through-hole.

The main body housing 500 of the sensing device 50 may further have an expansion hole 503 formed on its side. The expansion hole 503 is a hole through which the expansion cable 52 for connecting the expansion ECG module 51 passes toward the first circuit board 510.

A first sensing hole 505 is formed in a portion of the bottom plate 503. The first sensing hole 505 formed in the bottom plate 503 is located on the outside of the bottom plate 503 (diaphragm 540 side) and the inside of the main housing 500 (first circuit). The substrate 510 side) is connected.

A fastening protrusion 504 for fastening the diaphragm 540 is formed around the outer side of the bottom plate 503 (i.e., the side facing the subject). The end of the fastening protrusion 504 may be bent toward the side of the main housing 500 in order to easily fasten the diaphragm 540. A pressure hole (not shown) for placing the diaphragm 540 is formed on the lower surface of the main housing 500 by the fastening protrusion 504.

At this time, the diaphragm 540 is mounted at a predetermined distance from the bottom plate 503 of the main housing 500. In this way, when the diaphragm 540 is mounted to be spaced apart from the bottom plate 503 of the main body housing 500 at a predetermined interval, a transition space is formed between the bottom plate 503 of the main body housing 500 and the diaphragm 540. (R) (transient space) is formed.

When the sensing device 50 is worn on a subject, the diaphragm 540 formed on the sensing device 50 is in contact with the chest of the subject, and at this time, the heartbeat sound of the subject transmitted by deformation of the diaphragm 540 is It is amplified as it passes through the transition space (R) between the diaphragm 540 and the bottom plate 503. The degree of amplification of the subject's heartbeat sound transmitted by deformation of the diaphragm 540 may vary depending on the shape or size of the transition space R.

The amplified heartbeat sound is input to the auscultation sensor 513 provided on the first circuit board 510 through the first sensing hole 505. For reference, the auscultation sensor 513 is provided at a position corresponding to the first sensing hole 505 on the first circuit board 510. In addition, a transition hole (not shown) connecting the first sensing hole 505 and the auscultation sensor 513 may be further formed in the first circuit board 510. The transition hole may be formed with the same diameter or a smaller diameter than the first sensing hole 505.

The diaphragm 540 may be formed in a shape and material that further amplifies the wavelength region representing the heartbeat of the subject. For example, the diaphragm 540 may have a surface in contact with the subject in the form of a flexible plate.

Additionally, the diaphragm 540 is formed in the form of a thin rubber film, and may be formed in the shape of a convex lens or a dome that is convex toward the subject.

A sealing pad 550 may be further provided between the bottom plate 503 of the main housing 500 and the first circuit board 510.

The sealing pad 550 is in close contact with the bottom plate 503 of the main housing 500 and the first circuit board 510 to prevent heartbeat sounds from leaking out.

The sealing pad 550 has a second sensing hole 551 with a smaller diameter than the first sensing hole 505 formed in the bottom plate 503 of the main body housing 500 at a position corresponding to the first sensing hole 505. is formed For reference, if a transition hole is formed in the first circuit board 510, the transition hole may be formed to have the same diameter or a smaller diameter than the second sensing hole 551.

The sensing device 50 is capable of amplifying only sounds of a desired wavelength by adjusting the diameters of the first sensing hole 505 and the second sensing hole 551. For example, since the auscultation sensor 513 measures even minute sounds, noise is also measured in addition to the subject's heartbeat. By adjusting the diameters of the first sensing hole 505 and the second sensing hole 551, the desired wavelength is adjusted. If only the sound is amplified, only the desired sound (i.e. heartbeat sound) can be measured through the auscultation sensor 513.
