Description

Wearable sensing device with easy sensor replacement and diagnostic device using the same

The present invention relates to a wearable sensing device and a diagnosis device using the same, and more particularly, to a wearable sensing device in which a sensor can be easily replaced and a diagnosis device using the same.

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

In particular, among the biosignals collected from the user, 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, methods of measuring the respiratory rate or respiratory rate of a subject include spirometry and capnometry.

Spirometry is a method of measuring the flow of air entering and leaving the lungs using a spirometry, and capnometry is a method of measuring CO2 according to respiration. Although this conventional method has relatively high accuracy, there are limitations in that additional equipment is required and continuous monitoring is difficult.

Heart sounds are the sounds produced when the heart contracts and expands. Heart sound can generally be checked through a stethoscope, but when heart sound is checked through a stethoscope, since other noises are collected together, a filter for removing noise must exist.

In addition, when several 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, since animals such as dogs (including puppies), cats, and birds may have changes in respiration rate and heart rate depending on the external temperature even if abnormal symptoms are not expressed, an increase in the subject's respiration or heart rate may be an abnormal condition (e.g., For example, it is important to determine whether it is caused by disease) or external temperature. However, since the conventional measuring device does not consider the external temperature at all, if the external temperature of the test subject is higher than the standard value or colder than the standard value and the respiratory rate or heart rate increases due to the effect of the temperature, the test subject is in a normal state. and an error that is judged as an abnormal state may occur.

The problem to be solved by the present invention is to measure the subject's respiratory rate through a sensing value that is changed through the tensile force of the strap according to the subject's respiration, and measure the subject's heart rate through the amplified heart rate through the diaphragm.

1 is a perspective view showing a wearable sensing device 10 (hereinafter referred to as 'sensing device') according to a first embodiment of the present invention.

The sensing device 10 is worn on the body of the subject through the strap (S). The sensing device 10 calculates the respiratory rate by measuring the pressure applied to the pressure sensor 230 by the tensile force of the strap S when the subject breathes. The sensing device 10 measures the heart rate of the subject through a heartbeat amplified through the diaphragm 240 in contact with the chest of the subject.

The strap S may be implemented in the form of a band to be worn on the subject. Members such as buckles (not shown), snap buttons (not shown), or Velcro (not shown) are provided at both ends of the strap (S) to facilitate putting on and off the strap (S). The strap (S) is implemented to have elasticity or to adjust its length, so that it can provide a comfortable fit according to the body shape of the subject.

An extended ECG module 160 (electrocardiogram) may be selectively further connected to the sensing device 10 .

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

The sensing device 10 includes

main body housings

100 and 200, a circuit board 210 embedded in the

main body housings

100 and 200, a pressure sensor 230 (force sensor), and sensors. Cover 130 (sensor cover) is included.

The body housings 100 and 200 form an outer shape of the sensing device 10 .

The body housings 100 and 200 are worn on the body of the subject, that is, the chest, through the strap S.

The body housings 100 and 200 include an upper case 100 and a lower case 200 .

The upper case 100 may have a circular cross section. In another embodiment, the cross-sectional shape of the upper case 100 may be formed in a quadrangular or polygonal shape. Upper case 100 is formed with a pair of fastening holes 110 through which the strap (S) passes through the facing side.

A cover receiving groove 120 is formed inside the upper case 100 . The cover receiving groove 120 is formed in a direction parallel to the through direction of the strap. The cover receiving groove 120 may be formed inside the upper case 100 at a height capable of contacting the circuit board 210 mounted on the lower case 200 or spaced apart from the circuit board 210 by a predetermined distance. It can be formed at any height.

The sensor replacement hole 121 is formed in a part of the cover seating groove 120 . The sensor replacement hole 121 is a hole for easily replacing the pressure sensor 230 mounted on the circuit board 210 even when the upper case 100 and the lower case 200 are coupled. The sensor replacement hole 121 may expose a part of the pressure sensor 230 mounted on the circuit board 210 . In one embodiment, the sensor replacement hole 121 is formed to have the same cross-sectional shape as that of the pressure sensor 230, but may be formed to a predetermined size larger than the cross-sectional area of the pressure sensor 230.

The sensor cover 130 is seated on the upper surface of the cover receiving groove 120 of the upper case 100 . The sensor cover 130 may be formed to a size that completely covers the sensor replacement hole 121 . The sensor cover 130 covers the sensor replacement hole 121 and also covers the pressure sensor 230 exposed through the sensor replacement hole 121 . The sensor cover 130 may be formed in a dome shape with a convex top. Alternatively, the sensor cover 130 may be formed with a thicker thickness at the center than at the circumference. Through this, the sensor cover 130 can receive the tensile force of the strap (S) more sensitively.

The sensor cover 130 is made of a flexible material. For example, the sensor cover 130 may be formed of a material such as rubber or silicon. The sensor cover 130 prevents the pressure sensor 230 from being damaged while the strap (S) contacts the pressure sensor 230 when the strap (S) is tensioned. In addition, the sensor cover 130 prevents the pressure sensor 230 from falling off to the outside. The sensor cover 130 is fixed in position by the force pressed by the strap (S), and when the strap (S) is removed, it may be removed from the cover receiving groove 120.

A sensor fixing groove (not shown) corresponding to at least a part of the shape of the pressure sensor 230 is formed on a lower surface of the sensor cover 130, that is, a surface in contact with the pressure sensor 230.

The strap (S) is disposed to cross the upper surface of the sensor cover 130 through the through hole of the fastening hole 110 and the cover mounting groove 120 of the upper case 100.

The lower case 200 is coupled to the lower portion of the upper case 100 . The lower case 200 has the same cross-sectional shape as the upper case 100 . A battery B and a circuit board 210 are mounted in the lower case 200 therein.

The battery B is disposed under the circuit board 210 inside the lower case 200 . The battery B supplies power to the circuit board 210 . Battery B may be charged in a wired or wireless manner. When the battery B is wirelessly charged, a wireless charging module may be further provided on the circuit board 210 . When the battery B is charged in a wired manner, a charging hole (not shown) through which a charging cable passes may be formed at one side of the lower case 200 . The charging cable passes through the charging hole and is connected to a charging terminal (not shown) formed on the circuit board 210 .

The circuit board 210 is disposed above the battery B. An electric circuit is patterned on the circuit board 210 so that the pressure sensor 230, the battery B, the extended ECG module 160, the auscultation sensor 241, and the like are connected.

The circuit board 210 may include a spacer bridge 211 spaced apart from the inner surface of the bottom plate 203 of the lower case 200 by the height of the battery B.

A pressure sensor 230 is mounted on the circuit board 210 . One side of the circuit board 210 is provided with a socket-type terminal 220 to which the pressure sensor 230 is connected. For example, one side of the circuit board 210 may mean an upper surface facing the upper case 100 . The socket-type terminal 220 may be formed to protrude from an upper surface of the circuit board 210 to a predetermined height.

In a state where the pressure sensor 230 is disposed on the upper surface of the circuit board 210, a protruding terminal 231 formed on one side of the pressure sensor 230 is connected to the socket-type terminal 220. The direction of connection between the pressure sensor 230 and the socket-type terminal 220 is different from the direction of coupling between the upper case 100 and the lower case 200 (for example, a direction perpendicular to it). For reference, the sensor replacement hole 121 is formed in a shape corresponding to the pressure sensor 230 and the protruding terminal 231 of the pressure sensor 230 .

The pressure sensor 230 measures the pressure generated by the tension of the strap (S) according to the subject's respiration. For example, when the subject breathes, the thorax repeatedly contracts and expands. When the chest of the subject is inflated, a tensile force is generated in the strap (S), and the sensor cover 130 and the pressure sensor 230 are pressed while the strap (S) is stretched. The pressure sensor 230 transmits a measurement signal to the circuit board 210 .

A sound transmission tube 201 is formed on a part of the bottom plate 203 of the lower case 200 . The sound transmission pipe 201 may be formed through the bottom plate 203 . That is, the sound transmission pipe 201 communicates the outer surface (diaphragm 240 side) and the inner surface (circuit board 210 side) of the bottom plate 203 . The sound transmission tube 201 is formed at a height capable of contacting the circuit board 210 from the inner surface of the bottom plate 203 of the lower case 200 . The sound transmission pipe 201 is formed on the inner surface of the bottom plate 203 of the lower case 200 at a position opposite to the auscultation sensor 241.

A diaphragm 240 made of a flexible material may be further coupled to a lower portion of the lower case 200 (a side facing the subject). A fastening protrusion 204 for fastening the diaphragm 240 is formed on the lower circumference of the bottom plate 203 . An end of the fastening protrusion 204 may be bent toward the side of the lower case 200 so that the diaphragm 240 can be easily fastened thereto.

The diaphragm 240 is mounted on the fastening protrusion 204 so as to cover the entire bottom plate 203 of the lower case 200 . At this time, the diaphragm 240 is mounted to be spaced apart from the bottom plate 203 of the lower case 200 at a predetermined interval. In this way, when the diaphragm 240 is mounted to be spaced apart from the bottom plate 203 of the lower case 200 at a predetermined interval, there is a transition space between the bottom plate 203 of the lower case 200 and the diaphragm 240. (R) (transient space) is formed.

When the sensing device 10 is worn on a subject, the diaphragm 240 formed in the sensing device 10 is in contact with the chest of the subject, and at this time, the heartbeat of the subject transmitted by the deformation of the diaphragm 240 is It is amplified or modulated while passing through the transition space (R) between the diaphragm 240 and the bottom plate 203. For example, the degree of amplification or modulation of the subject's heartbeat sound transmitted by deformation of the diaphragm 240 may vary according to the shape or size of the transition space R.

The amplified or modulated heartbeat sound is input to the auscultation sensor 241 provided on the circuit board 210 through the sound transmission tube 201 . For reference, the stethoscope sensor 241 is provided at a position corresponding to the sound transmission pipe 201 on the circuit board 210 . In addition, a transition hole (not shown) connecting the sound transmission tube 201 and the auscultation sensor 241 may be further formed in the circuit board 210 . The transition hole may have the same diameter as the sound transmission tube 201 or a smaller diameter.

The diaphragm 240 may be formed of a shape and material that further amplifies a wavelength region representing the heartbeat of the subject. For example, the surface of the diaphragm 240 in contact with the test subject may be formed in the form of a flexible plate. In addition, the diaphragm 240 may be formed in the form of a thin film made of a rubber material, and may be formed in the shape of a convex lens or dome convexly formed toward the object under examination.

Between the upper surface of the sound transmission pipe 201 formed in the lower case 200 and the lower surface of the circuit board 210 (that is, the location corresponding to the placement point of the auscultation sensor 241), there is a ring-shaped sealing pad (not shown). ) may be further arranged. The sealing pad may be formed inside the sound transmission pipe 201. The sealing pad prevents heartbeat sound transmitted from the sound transmission tube 201 from leaking out.

The sealing pad changes the diameter of the end (circuit board side) of the sound transmission pipe 201 according to the thickness. That is, the sealing pad has a different diameter from that of the diaphragm 240 and the circuit board 210 . It is possible to amplify or modulate only sound of a desired wavelength by adjusting the end diameter of the sound transmission tube 201 through the sealing pad. For example, since even minute sounds are measured through the auscultation sensor 241, noise can be measured in addition to the heartbeat of the subject. Auscultation can be achieved by adjusting the diameter of the end of the sound transmission tube 201 to amplify or modulate only the sound of a desired wavelength. Only a desired sound (ie, heartbeat) may be measured through the sensor 241 .

In the above-described sensing device 10, the pressure sensor 230 whose life has expired can be replaced through the sensor replacement hole 121 by removing only the strap S without separating the upper case 100 and the lower case 200. there is. In addition, the new pressure sensor 230 can be easily mounted on the sensing device 10 .

4 is a view showing a state in which the strap (S) presses the pressure sensor (230).

Referring to FIGS. 2 to 4 , when the chest of the subject is inflated, a tensile force in the horizontal direction is generated in the strap (S). As the strap (S) is tensioned and presses the sensor cover 130, the force transmitted to the sensor cover 130 is transmitted to the pressure sensor 230 again.

When the chest of the test subject is contracted, the tensile force in the strap (S) is reduced, and the force transmitted to the pressure sensor (230) through the sensor cover (130) is reduced. The pressure sensor 230 measures the pressure according to the changed tension of the strap (S).

In the pressure sensor 250, a connection terminal (not shown) for connection to the circuit board 210 is formed on the lower surface (the surface in contact with the circuit board 210). A contact type terminal 251 for connection of the pressure sensor 250 is provided on a surface (upper surface) of the circuit board 210 in contact with the pressure sensor 250 . The pressure sensor 250 and the contact type terminal 251 have a connection direction parallel to the coupling direction of the upper case 100 and the lower case 200 .

In this way, the sensing device 10 can replace the pressure sensor 250 whose life has expired through the sensor replacement hole 121 by removing only the strap S without separating the upper case 100 and the lower case 200. there is. In addition, the new pressure sensor 250 can be easily mounted on the sensing device 10 .

The extended ECG module 160 (electrocardiogram) is selectively connected to the sensing device 10. The extended ECG module 160 is attached to the subject's body, that is, the subject's arms, legs, or abdomen, and records the action current according to the contraction of the heart as a curve.

The extension ECG module 160 may be connected to an interface circuit (not shown) provided on the circuit board 210 through an extension cable 161 . At this time, the extension cable 161 is connected to an external connection terminal (not shown) connected to an interface circuit (not shown). If the extended ECG module 160 is wirelessly connected to the interface circuit, an external connection terminal may not be provided.

The extended ECG module 160 may include one or more electrocardiogram sensors, and even when the electrocardiogram sensor includes two or more, it may be connected to an interface circuit provided on the circuit board 210 through a single extension cable.

The sensing device 10 shown in FIG. 1 may further include a communication circuit 11 connected to an external device 12 as shown in FIG. 6 . The communication circuit 11 is provided on the circuit board 210 .

The communication circuit 11 transmits the measurement signal of the pressure sensor and the measurement signal of the auscultation sensor to the external device 12 . Here, the external device 12 may mean a diagnosis device (not shown) or an analysis device (not shown). The diagnosis device or analysis device receives at least one waveform signal of a heartbeat waveform signal (measurement signal of the auscultation sensor 241) and a respiration waveform signal (measurement signal of the pressure sensor) from the sensing device 10, and receives the provided waveform signal. At least one of the heart rate and the respiratory rate of the subject may be calculated through. In addition, the diagnosis device or analysis device may determine the abnormal state of the test subject through the heart rate, respiratory rate, or electrocardiogram of the test subject.

Meanwhile, the sensing device 10 may further include a temperature sensor (not shown). The temperature sensor measures the external temperature of the sensing device 10 . Here, the external temperature means the temperature of an examination room in which an examination of a subject is performed. The communication circuit 11 provides the temperature measured by the temperature sensor to a diagnosis device or analysis device. The diagnosis device or analysis device may determine the abnormal state of the test subject by comprehensively considering at least one of the heart rate or respiration rate of the subject 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 diagnosis device or analysis device determines whether it is caused by an abnormal condition (eg, disease) or external temperature. If at least one of the heart rate or respiratory rate of the subject increases or decreases despite the external temperature being within an appropriate room temperature, the diagnosis device or analysis device determines that an abnormal state has occurred in the subject. When the external temperature is out of the proper room temperature, the diagnosis device or the analysis device determines that the increase or decrease of at least one of the heart rate and the respiratory rate of the subject is caused by the external temperature.

Here, an appropriate temperature range (room temperature) that does not seriously affect the determination of the abnormal state of the subject may be between 22 and 25 °, and when the temperature increases or decreases by 1 ° in the corresponding temperature range The subject's respiratory rate or heart rate, which is increased every time, can be checked from an algorithm or a pre-built DB.

7 is a block diagram showing the configuration of a sensing device 20 according to a second embodiment of the present invention.

The sensing device 20 of the second embodiment may be implemented in the same form as the sensing device 10 of the first embodiment, and a counting circuit 21 is further included on a circuit board (not shown). All other configurations except for the counting circuit 21 are the same as those of the first embodiment, so duplicate descriptions are omitted. Since the outer shape of the sensing device 20 is implemented in the same form as the sensing device 10 of the first embodiment, configurations related to the form except for the counting circuit 21, the communication circuit 22, and the external device 23 are implemented. The same reference numerals as the sensing device 10 of Example 1 will be described.

Respiration of the subject is divided into inhalation and expiration. In the process of inspiration, intercostal muscles contract to lift the ribs, and the diaphragm also contracts to go 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 that detects inspiration and expiration. Alternatively, it may refer to expansion and contraction of the ribcage in a narrower sense, and expansion and contraction of the lungs in a more narrow sense. That is, the definition of respiration in the present invention is interpreted as a comprehensive meaning of inspiration and expiration as well as expansion and contraction of the chest or lungs.

Here, when the subject breathes, the rib cage expands, and when the rib cage expands to the maximum value, it is the moment when the breathing changes, that is, the moment when the breath changes from inhalation to exhalation. When the ribcage expands during inspiration during respiration of the subject, a tensile force is generated in the strap S. At this time, while the strap (S) is tensioned and presses the sensor cover 130, the force transmitted to the sensor cover 130 is transmitted to the pressure sensor 230 again. The pressure sensor 230 measures the pressure according to the tensile force of the strap (S).

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

The heartbeat transmitted by the deformation of the diaphragm 240 is amplified while passing through a transient space (R) between the diaphragm 240 and the bottom plate 203, and the amplified heartbeat is transmitted to the lower case. It is measured by the auscultation sensor 241 through the sound transmission tube 201 formed in the bottom plate 203 of (200).

The counting circuit 21 calculates heartbeats per minute using the peak value of the heartbeat waveform measured by the auscultation sensor 241 and the next peak value.

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

Meanwhile, the sensing device 20 may further include a temperature sensor (not shown). The temperature sensor measures the external temperature of the sensing device 20 . Here, the external temperature means the temperature of an examination room in which an examination of a subject is performed. The communication circuit 22 provides the external temperature measured by the temperature sensor to the external device 23 (ie, a diagnosis device or an analysis device).

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

8 is a block diagram showing the configuration of a wearable sensing device 30 according to a third embodiment 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 a counting circuit 31 and a diagnosis circuit 33 are further included on the circuit board 210 . All other components except for the counting circuit 31 and the diagnosis circuit 33 are the same as those in the first embodiment, so duplicate descriptions are omitted. In addition, since the counting circuit 31 is the same as that of the second embodiment, redundant description will be omitted.

Since the outer shape of the sensing device 30 is implemented in the same form as the sensing device 10 of the first embodiment, the counting circuit 31, the communication circuit 32, the diagnosis circuit 33, and the external device 34 are excluded. Configurations related to will be described with the same reference numerals as those of the sensing device 10 of the first embodiment.

The diagnostic circuit 33 may determine an abnormal state of the subject through the heart rate or respiratory rate of the subject 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 heart rate and the respiratory rate of the subject increases or decreases. In addition, the diagnosis circuit 33 may determine that an abnormal state has occurred if the heart rate or respiratory rate of the subject is irregular.

Meanwhile, the sensing device 30 may further include 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 an examination room in which an examination of a subject is performed. The diagnostic circuit 33 determines an abnormal state of the subject by comprehensively considering at least one of the heart rate or respiration rate of the subject and the external temperature measured by the temperature sensor.

The wearable diagnosis device (40, hereinafter referred to as 'diagnosis device') of Example 4 is obtained by separating the sensor-related devices of Example 1 and the circuits for measuring the respiratory rate or heart rate through signals measured by the sensors. Components related to the sensor are built into the sensing device 50, and circuits for measuring respiration rate or heart rate are built into the arithmetic 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 in spite of being a small animal, a measurement error may occur. For example, in the case of a small breed of dog, 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 a small breed of dog, resulting in a measurement error.

According to the fourth embodiment, it is possible to design the size of the sensing device 10 to be small by embedding a sensor-related device in the sensing device 50 and separating the remaining components from the arithmetic device 60 .

FIG. 10 is a cross-sectional view of the sensing device 50 shown in FIG. 9 . Referring to FIGS. 9 and 10 , the diagnosis device 40 of the fourth embodiment includes a sensing device 50 , an arithmetic device 60 , and a power communication line 41 .

Components related to the sensor are embedded in the sensing device 50 .

The sensing device 50 includes

body housings

500 and 600 to which an upper case 500 and a lower case 600 are coupled.

The upper case 500 has a circular cross section. As another example, the cross-sectional shape of the upper case 500 may be formed in a quadrangular or polygonal shape. Upper case 500 is formed with a pair of fastening holes 510 through which the strap (S) passes through the facing side.

A cover receiving groove 520 is formed inside the upper case 500 . The cover seating groove 520 is formed in a direction parallel to the through direction of the strap. The cover seating groove 520 may be formed inside the upper case 500 at a height capable of contacting the circuit board 610 mounted on the lower case 600 or spaced apart from the circuit board 610 by a predetermined distance. It can be formed at any height.

The sensor replacement hole 521 is formed through a part of the seating groove 520 of the cover 530 . The sensor replacement hole 521 is a hole for easily replacing the pressure sensor 630 mounted on the first circuit board 610 even when the upper case 500 and the lower case 600 are coupled. The sensor replacement hole 521 may expose a part of the pressure sensor 630 mounted on the circuit board 610 . In one embodiment, the sensor replacement hole 521 is formed to have the same cross-sectional shape as that of the pressure sensor 630, but may be formed to have a predetermined size larger than the cross-sectional area of the pressure sensor 630.

The sensor cover 530 is seated on the upper surface of the cover 530 seating groove 520 of the upper case 500 . The sensor cover 530 may be formed to a size that completely covers the sensor replacement hole 521 . The sensor cover 530 covers the sensor replacement hole 521 and also covers the pressure sensor 630 exposed through the sensor replacement hole 521 .

The sensor cover 530 is made of a flexible material. For example, the sensor cover 530 may be formed of a material such as rubber or silicon. The sensor cover 530 prevents the strap (S) from being damaged as the strap (S) contacts the pressure sensor 630 when the strap (S) is tensioned. In addition, the sensor cover 530 prevents the pressure sensor 630 from coming off to the outside. The sensor cover 530 is fixed in position by force pressed by the strap (S), and when the strap (S) is removed, the cover 530 may be removed from the seating groove 520.

A sensor fixing groove (not shown) corresponding to at least a part of the shape of the pressure sensor 630 is formed on a lower surface of the sensor cover 530, that is, a surface in contact with the pressure sensor 630.

The strap (S) passes through the fastening hole 510 of the upper case 500 and the through hole of the seating groove 520 of the cover 530 and is disposed to cross the upper surface of the sensor cover 530.

The lower case 600 is coupled to the lower portion of the upper case 500 . The lower case 600 has the same cross-sectional shape as the upper case 500 . The lower case 600 has a first circuit board 610 mounted therein.

The first circuit board 610 is spaced apart from the inner surface of the bottom plate 603 of the lower case 600 by a predetermined distance. The first circuit board 610 is patterned with an electric circuit such that the pressure sensor 630, the extended ECG module 51, and the auscultation sensor 641 are connected.

The first circuit board 610 may include a separation bridge 611 spaced apart from the inner surface of the bottom plate 603 of the lower case 600 by a predetermined height. Here, the predetermined height may be equal to the height of the sound transmission tube 601 formed in the lower case 600 .

A pressure sensor 630 is mounted on the first circuit board 610 . One side of the first circuit board 610 is provided with a socket-type terminal 620 to which the pressure sensor 630 is connected. For example, one side of the first circuit board 610 may mean an upper surface facing the upper case 500 . The socket-type terminal 620 may be formed to protrude from an upper surface of the first circuit board 610 to a predetermined height.

In a state where the pressure sensor 630 is disposed on the upper surface of the first circuit board 610, a protruding terminal 631 formed on one side of the pressure sensor 630 is connected to the socket-type terminal 620. The direction of connection between the pressure sensor 630 and the socket-type terminal 620 is different from (for example, a direction perpendicular to) the coupling direction of the upper case 500 and the lower case 600 . For reference, the sensor replacement hole 521 is formed in a shape corresponding to the pressure sensor 630 and the protruding terminal 631 of the pressure sensor 630 .

The pressure sensor 630 measures the pressure generated by the tension of the strap (S) according to the subject's respiration. For example, when a subject breathes, the thorax repeatedly contracts and expands. When the chest of the subject is inflated, tension is generated in the strap (S), and the sensor cover 530 and the pressure sensor 630 are pressed while the strap (S) is tensioned. The pressure sensor 630 transmits a measurement signal to the first circuit board 610 .

A sound transmission tube 601 is formed on a part of the bottom plate 603 of the lower case 600 . The sound transmission tube 601 may be formed through the bottom plate 603 . That is, the sound transmission pipe 601 communicates the outer surface (diaphragm 640 side) and the inner surface (first circuit board 610 side) of the bottom plate 603 . The sound transmission pipe 601 is formed at a height capable of contacting the first circuit board 610 from the inner surface of the bottom plate 603 of the lower case 600 .

A diaphragm 640 made of a flexible material may be further coupled to a lower portion of the lower case 600 (a side facing the subject). A fastening protrusion 604 for fastening the diaphragm 640 is formed on the lower circumference of the bottom plate 603 . An end of the fastening protrusion 604 may be bent toward the side of the lower case 600 so that the diaphragm 640 can be easily fastened thereto.

The diaphragm 640 is mounted on the fastening protrusion 604 so as to cover the entire bottom plate 603 of the lower case 600 . At this time, the diaphragm 640 is mounted to be spaced apart from the bottom plate 603 of the lower case 600 at a predetermined interval. As such, when the diaphragm 640 is mounted to be spaced apart from the bottom plate 603 of the lower case 600 at a predetermined interval, there is a transition space between the bottom plate 603 of the lower case 600 and the diaphragm 640. (R) (transient space) is formed.

When the sensing device 50 is worn on the subject, the diaphragm 640 formed in the sensing device 50 comes into contact with the chest of the subject, and at this time, the heartbeat of the subject transmitted by the deformation of the diaphragm 640 is It is amplified or modulated while passing through the transition space (R) between the diaphragm 640 and the bottom plate 603. For example, the degree of amplification or modulation of the subject's heartbeat sound transmitted by deformation of the diaphragm 640 may vary depending on the shape or size of the transition space R.

The amplified or modulated heartbeat sound is input to the auscultation sensor 641 provided on the first circuit board 610 through the sound transmission pipe 601 . For reference, the stethoscope sensor 641 is provided at a position corresponding to the sound transmission tube 601 on the first circuit board 610 . In addition, a transition hole (not shown) connecting the sound transmission pipe 601 and the auscultation sensor 641 may be further formed in the first circuit board 610 . The transition hole may have the same diameter as the sound transmission pipe 601 or a smaller diameter.

The diaphragm 640 may be formed of a shape and material that further amplifies a wavelength region representing the heartbeat of the subject. For example, the surface of the diaphragm 640 in contact with the object under test may be formed in the form of a flexible plate. In addition, the diaphragm 640 may be formed in the form of a thin film made of a rubber material, and may be formed in the shape of a convex lens or dome convexly formed toward the object under test.

Between the upper surface of the sound transmission pipe 601 formed in the lower case 600 and the lower surface of the first circuit board 610 (that is, the location corresponding to the placement point of the auscultation sensor 641), there is a ring-shaped sealing pad. (not shown) may be further disposed. The sealing pad prevents the heartbeat sound transmitted from the sound transmission tube 601 from leaking out. The sealing pad may be formed inside the sound transmission pipe 601.

In addition, the sealing pad changes the diameter of the end of the sound transmission pipe 601 (side of the first circuit board) according to the thickness. That is, the sealing pad has a different diameter from that of the diaphragm 640 and the first circuit board 610 . It is possible to amplify or modulate only the sound of a desired wavelength by adjusting the end diameter of the sound transmission tube 601 through the sealing pad. For example, since even minute sounds are measured through the auscultation sensor 641, noise can be measured in addition to the heartbeat of the subject. Auscultation can be achieved by amplifying or modulating only the sound of a desired wavelength by adjusting the diameter of the end of the sound transmission tube 601. Only a desired sound (ie, heartbeat) may be measured through the sensor 641 .

The extended ECG module 51 (electrocardiogram) is selectively connected to the sensing device 50. The extended ECG module 51 is attached to the subject's body, that is, the arm, leg 611 or abdomen of the subject, and records the action current according to the contraction of the heart in a curve.

The extension ECG module 51 may be connected to an interface circuit (not shown) provided on the first circuit board 610 through an extension cable 52 . At this time, the extension cable 52 is connected to an external connection terminal (not shown) connected to an interface circuit (not shown). If the extended ECG module 51 is wirelessly connected to the interface circuit, an external connection terminal may not be provided.

The extended ECG module 51 may include one or more electrocardiogram sensors, and may be connected to an interface circuit provided on the first circuit board 610 through one extension cable even when the electrocardiogram sensor includes two or more.

In the above-described sensing device 50, the pressure sensor 630 whose life has expired can be replaced through the sensor replacement hole 521 by removing only the strap S without separating the upper case 500 and the lower case 600. there is. In addition, the new pressure sensor 630 can be easily mounted on the sensing device 50 .
