Description

Wearable sensing device and diagnostic system for measuring multiple biological signals {WEARABLE DEVICE AND DIAGNOSTIC SYSTEM FOR SENSING MULTIPLE BODY SIGNALS}

The present invention relates to a wearable sensing device and diagnostic system for measuring multiple biological signals. More specifically, the present invention relates to a wearable sensing device and diagnostic system for measuring multiple biosignals. More specifically, the present invention measures the respiratory rate of a subject through a sensing value that changes through the tension of the strap according to the subject's breathing, and This relates to a wearable sensing device and diagnostic system that can measure the heart rate of a subject through heartbeat sounds amplified through a prom.

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, to measure heart sounds and breathing sounds simultaneously, both a sensor for sensing breathing and a sensor for sensing heart sounds must be provided, so a stethoscope equipped with all of these sensors has the disadvantage of being expensive. In addition, the internal structure of the stethoscope is complicated, which has disadvantages 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.

However, this is not intended to limit the present invention to any specific embodiment, and all transformations, equivalents, and substitutions including the technical spirit of the present invention should be understood to be included in the scope of the present invention. do.

In this specification, singular expressions include plural expressions, unless the context clearly dictates otherwise.

In this specification, when it is stated that one configuration “has” or “comprises” a certain sub-configuration, it does not exclude the other configuration but adds the other configuration, unless specifically stated to the contrary. This means that it may be included.

In this specification, the terms "...Unit", "...Module", and "Component" mean a unit that processes at least one function or operation, and includes hardware, software, or It can also be implemented through a combination of hardware and software.

FIG. 1 is a perspective view of the wearable sensing device 10 according to Embodiment 1 of the present invention viewed from above, and FIG. 2 is a perspective view of the sensing device 10 illustrated in FIG. 1 viewed from below.

The sensing device 10 is worn on the subject's body through a strap (S), and measures the change in shape of the pressing frame 230 (230 in FIG. 3) due to the tightening of the strap (S) when the subject breathes. The respiratory rate is calculated, and the subject's heart rate is measured through the heartbeat sound amplified through the diaphragm 240 in contact with the subject's chest.

The strap S may be implemented in the form of a band so that it can 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 taking off the strap (S). The strap (S) is implemented to have elasticity or an adjustable length, so that it can provide a comfortable fit according to the body type of the subject.

An external ECG module 250 (electrocardiogram) may be optionally further connected to the sensing device 10. The external ECG module 250 is attached to the subject's body and records the action current according to heart contraction as a curve. The external ECG module 250 may be equipped with one or more electrocardiogram sensors, and can be connected to the sensing device 10 through one extension cable 251 even when there are two or more electrocardiogram sensors.

FIGS. 3 and 4 are exploded perspective views of the sensing device 10 illustrated in FIG. 1 .

The sensing device 10 includes an upper case 100 and a lower case 200.

The upper case 100 is one of the cases that forms the external shape of the sensing device 10, and may be formed in a square shape, a circle, or another shape.

The upper case 100 has a pair of fastening holes 110 formed on the side for fastening the strap S. The strap (S) penetrates across the interior of the upper case (100) through a pair of fastening holes (110). The upper part of the upper case 100 is open so that the strap (S) is visible. The reason is to enable replacement of the pressure frame 230 and strain sensor 233 by removing only the strap (S) without separating the upper case 100 and lower case 200.

The lower surface 101 of the upper case 100 is formed to have a concave curved shape toward the inside of the upper case 100. For example, when the strap S is worn on the subject's body, the strap S has a circular shape, and the lower surface 101 of the upper case 100 is formed in a curved shape similar to the shape of the strap S. do.

The upper case 100 has a pressure hole 102 formed on the lower surface 101. The pressing hole 102 is a hole through which a portion of the pressing frame 230 mounted on the lower case 200 protrudes toward the inside of the lower case 200. One surface of the pressing frame 230 is in contact with the strap (S) while exposed to the pressing hole (102). The pressing frame 230 will be described again below.

The lower case 200 is coupled to the lower part of the upper case 100. The lower case 200 has a built-in circuit board 210 and a battery 220 that supplies power to the circuit board 210.

The lower case 200 has an expansion hole 201 formed on its side. The expansion hole 201 is a hole through which the expansion cable 251 for connecting the external ECG module 250 passes.

The lower case 200 has a charging hole 202 formed on the side. The charging hole 202 is a hole through which a charging cable (not shown) for charging the sensing device 10 passes.

The circuit board 210 is disposed on the bottom of the lower case 200, that is, under the pressing frame 230. The reason is to prevent interference when the pressing frame 230 is attached and detached to the open upper part of the upper case 100. The circuit board 210 is configured with an electric circuit to connect the strain sensor 233, battery 220, external ECG module 250, and auscultation sensor 242 (242 in FIG. 3).

The battery 220 may be placed on top of the circuit board 210 . The battery 220 can be supplied with power through wired charging or wireless charging, and when supplied with power through wireless charging, the circuit board 210 may be further equipped with a wireless charging module (not shown). When the battery 220 is charged by wire, a charging hole 202 through which the charging cable passes may be formed on the side of the lower case 200. The charging cable may pass through the charging hole 202 and be connected to the charging terminal 212 formed on the circuit board 210.

The pressing frame 230 is mounted on the lower case 200 so that at least a portion is exposed to the pressing hole 102 of the upper case 100.

The pressing frame 230 may be formed of a material having a predetermined elasticity. For example, the pressing frame 230 may be formed of a thin plastic plate or a thin metal plate.

The pressing frame 230 is formed in the shape of an ‘L’ shaped plate with a portion of it bent.

The pressure frame 230 includes a support plate 232 and a pressure plate 231.

The support plate 232 is mounted on one side of the lower case 200, that is, in the slot 211 formed on the inner surface. The support plate 232 may be mounted in the slot 211 in a mounting direction parallel to the coupling direction of the upper case 100 and the lower case 200. The support plate 232 can be mounted on the slot 211 through the open top of the upper case 100 when the upper case 100 and the lower case 100 are combined and the strap (S) is removed. The upper case 100 is formed in a structure that is coupled to the lower case 200 without interfering with the entrance of the slot 206, and the upper part of the upper case 100 is open so that the strap (S) is visible. The pressure frame 230 and the strain sensor 233 can be replaced by only removing the strap (S) without separating the (100) and the lower case (100). Since the pressure frame 230 is easily mounted and detached from the slot 211, it is easy to replace the pressure frame 230 or the strain sensor according to its lifespan.

The pressure plate 231 extends from the upper part of the support plate 232 in a bent shape. The pressure plate 231 may be formed integrally with the support plate 232. The pressure plate 231 may be formed of a thin plastic plate or a thin metal plate. For reference, only the pressure plate 231 may be formed of a thin plastic plate or a thin metal plate, and the support plate 232 may be formed of a non-elastic material.

The pressure plate 231 of the pressure frame 230 is exposed to the inside of the upper case 100 through the pressure hole 102 of the upper case 100. The shape of the pressure plate 231 changes due to the tightening of the strap (S) when the subject breathes and the chest expands. The change in shape of the pressure plate 231 means that the pressure plate 231 is bent toward the lower case 200 due to the tightening of the strap (S). Since the pressure plate 231 is made of an elastic material, when the subject's chest is contracted, the tightness of the strap (S) is relieved and restored to its original position.

A strain sensor 233 is attached to a portion of the pressure plate 231 of the pressure frame 230. The strain sensor 233 measures the change in shape of the pressure frame 230 (i.e., the pressure plate 231) due to the tightening of the strap (S) and transmits it to the circuit board 210.

The strain sensor 233 may be attached to the lower surface of the pressure plate 231 or the upper surface of the pressure plate 231. The strain sensor 233 may be formed in a size corresponding to the entire surface of the pressure plate 231, or may be formed in a size corresponding to a portion of one surface of the pressure plate 231. The strain sensor 233 may be replaced with a strain gauge.

An ECG module (electrocardiogram) is optionally connected to the sensing device 10. The external ECG module 250 is attached to the subject's body, that is, the subject's arms, legs, or abdomen, and records the action current according to heart contraction as a curve.

The external ECG module 250 may be connected to an interface circuit (not shown) provided on the circuit board 210 through an extension cable 251. At this time, the extension cable 251 is connected to the external connection terminal 213 connected to the interface circuit (not shown). If the external ECG module 250 is wirelessly connected to the interface circuit, the external connection terminal 213 may not be provided.

The external ECG module 250 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 circuit board 210 through one extension cable 251.

FIG. 5 is a cross-sectional view of the sensing device 10 illustrated in FIG. 1 .

As shown in Figures 3 to 5, a bottom plate 203 is provided at the bottom of the lower case 200.

A first sensing hole 205 is formed in a portion of the bottom plate 203. The first sensing hole 205 formed in the bottom plate 203 communicates with the outside of the bottom plate 203 (diaphragm 240 side) and the inside of the lower case 200 with the bottom plate 203 as the reference.

A fastening protrusion 204 for fastening the diaphragm 240 is formed around the outer side of the bottom plate 203 (i.e., the side facing the subject). The end of the fastening protrusion 204 may be bent toward the side of the lower case 200 in order to easily fasten the diaphragm 240.

The diaphragm 240 is mounted on the fastening protrusion 204 to cover the entire bottom plate 203 of the lower case 200. At this time, the diaphragm 240 is mounted at a predetermined distance from the bottom plate 203 of the lower case 200. 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, a transition space is formed 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 sound of the subject transmitted by deformation of the diaphragm 240 is It is amplified as it passes through the transition space (R) between the diaphragm 240 and the bottom plate 203. The degree of amplification of the subject's heartbeat sound transmitted by deformation of the diaphragm 240 may vary depending on the shape or size of the transition space (R).

The amplified heartbeat sound is input to the auscultation sensor 242 provided on the circuit board 210 through the first sensing hole 205. For reference, the auscultation sensor 242 is provided at a position corresponding to the first sensing hole 205 on the circuit board 210. In addition, a transition hole (not shown) connecting the first sensing hole 205 and the auscultation sensor 242 may be further formed in the circuit board 210. The transition hole may be formed with the same diameter or a smaller diameter than the first sensing hole 205.

The diaphragm 240 may be formed in a shape and material that further amplifies the wavelength region representing the heartbeat of the subject. For example, the diaphragm 240 is formed in the form of a thin rubber film and may be provided with a flexible plate in the shape of a flat plate or a convex lens or dome that is convex toward the subject.

A sealing pad 260 may be further provided between the bottom plate 203 of the lower case 200 and the circuit board 210.

The sealing pad 260 is in close contact with the bottom plate 203 and the circuit board 210 of the lower case 200 to prevent heartbeat sounds from leaking out.

The sealing pad 260 has a second sensing hole 261 with a smaller diameter than the first sensing hole 205 formed in the bottom plate 203 of the lower case 200 at a position corresponding to the first sensing hole 205. is formed For reference, if a transition hole is formed in the circuit board 210, the transition hole may be formed to have the same diameter or a smaller diameter than the second sensing hole 261.

The sensing device 10 is capable of amplifying only sounds of a desired wavelength by adjusting the diameters of the first sensing hole 205 and the second sensing hole 261. For example, since the auscultation sensor 242 measures even minute sounds, noise is also measured in addition to the subject's heartbeat. By adjusting the diameters of the first sensing hole 205 and the second sensing hole 261, 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 242.

Figure 6 is a partially enlarged cross-sectional view showing the pressing frame 230 of Figure 5 being pressed by the strap (S). Figure 7 is a perspective view showing the strap S of Figure 5 in a relaxed state.

For reference, Figures 5 and 7 show a state in which the chest is contracted and the strap (S) is relaxed when the subject's breathing is exhalation, and the strap (S) is relaxed and does not press the pressing frame 230. Figure 6 shows a state in which the pressurizing frame 230 is pressed while the chest is expanded and the strap (S) is tightened when the subject's breathing is inhalation.

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.

As shown in FIG. 6, when the subject inhales during breathing, the chest expands, which tightens the strap (S) and presses the pressurizing frame (230). As shown in FIG. 7, the chest contracts during exhalation of the subject, and as a result, the strap S is relaxed and the force pressing the pressing frame 230 becomes weak.

The strain sensor 233 attached to the pressurizing frame 230 measures the change in shape of the pressurizing frame 230 due to the subject's breathing.

FIG. 8 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 8, the sensing device 10 may further include a communication circuit 11.

The communication circuit 11 is provided on the circuit board 210.

The communication circuit 11 transmits the measurement signal from the strain sensor 233 and the measurement signal from the auscultation sensor to the external device 12. Here, the external device 12 may mean a diagnostic system (not shown) or an analysis device (not shown). The diagnostic system or analysis device receives at least one waveform signal of a heart rate waveform (measurement signal from the stethoscope sensor 242) 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 system or analysis device may determine the abnormal state of the subject through the subject's heart rate, respiratory 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 system or analysis device.

The diagnostic system 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 breathing rate increases or decreases, the diagnostic system 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 9 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 the circuit board. All other components except for the counting circuit 21 are the same as those in Embodiment 1, so redundant description will be omitted.

When the subject inhales during breathing, the chest expands, which tightens the strap and presses on the pressurizing frame. Also, when the subject exhales during breathing, the chest contracts, which causes the strap to relax and the force pressing the pressurizing frame to weaken. The strain sensor attached to the pressurizing frame measures the change in shape of the pressurizing frame due to the subject's breathing.

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 between the diaphragm and the bottom plate, and the amplified heartbeat sound is auscultated through the first sensing hole formed in the bottom plate of the lower case. It is measured by the sensor.

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.

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 system or an analysis device, and the diagnostic system 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 system or analysis device).

The diagnostic system 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 10 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 condition 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 subject is tested.

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 11 is a perspective view showing the configuration of a wearable diagnostic system 40 according to Embodiment 4 of the present invention.

The diagnostic system 40 of Embodiment 4 is a configuration of Embodiment 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 70.

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 50 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 70.

FIG. 12 is a cross-sectional view of the sensing device 50 shown in FIG. 11.

11 and 12, the diagnostic system 40 of Embodiment 4 includes a sensing device 50, an arithmetic device 70, and a power communication line 51.

The sensing device 50 is equipped with sensor-related components.

The sensing device 50 includes an upper case 500 and a lower case 600.

The upper case 500 of the sensing device 50 is one of the cases that forms the external shape of the sensing device 50, and may be formed in a square shape, circular shape, or other shape.

The upper case 500 of the sensing device 50 has a pair of fastening holes 510 formed on the side for fastening the strap S. The strap (S) penetrates across the interior of the upper case (500) through a pair of fastening holes (510). The upper part of the upper case 500 is open so that the strap (S) is visible. The reason is to enable replacement of the pressure frame 630 and strain sensor 633 by removing only the strap (S) without separating the upper case 500 and lower case 600.

The lower surface 501 of the upper case 500 is formed to have a concave curved shape toward the inside of the upper case 500. For example, when the strap S is worn on the subject's body, the strap S has a circular shape, and the lower surface 501 of the upper case 500 is formed in a curved shape similar to the shape of the strap S. do.

The upper case 500 has a pressure hole 502 formed on the lower surface 501. The pressing hole 502 is a hole through which a portion of the pressing frame 630 mounted on the lower case 600 protrudes toward the inside of the lower case 600. One surface of the pressing frame 630 is in contact with the strap (S) while exposed to the pressing hole 502. The pressing frame 630 will be described again below.

The lower case 600 of the sensing device 50 is coupled to the lower part of the upper case 500. The lower case 600 of the sensing device 50 is equipped with a first circuit board 610 and a pressure frame 630 to which a strain sensor 633 is attached.

The lower case 600 of the sensing device 50 has a communication penetration hole 602 formed on the side through which the power communication line 51 passes. The power communication line 51 is connected to the communication terminal 612 of the first circuit board 610 through the communication through hole 602.

The lower case 600 of the sensing device 50 may further have an expansion hole 601 formed on its side. The expansion hole 601 is a hole through which the expansion cable 53 for connecting the external ECG module 52 passes toward the first circuit board 610.

The first circuit board 610 is disposed on the bottom of the lower case 600. The circuit board 610 is configured with an electric circuit to connect the strain sensor 633, the external ECG module 52, the auscultation sensor 842, etc.

The pressing frame 630 is mounted on the lower case 600 of the sensing device 50 so that at least a portion is exposed to the pressing hole 502 of the upper case 500 of the sensing device 50.

The pressing frame 630 may be formed of a material having a predetermined elasticity. For example, the pressing frame 630 may be formed of a thin plastic plate or a thin metal plate.

The pressing frame 630 is formed in the shape of an ‘L’ shaped plate with a portion of it bent.

The pressure frame 630 includes a support plate 632 and a pressure plate 631.

The support plate 632 is mounted on one side of the lower case 600 of the sensing device 50, that is, in the slot 611 formed on the inner side. The support plate 632 may be mounted in the slot 611 in a mounting direction parallel to the coupling direction of the upper case 500 and lower case 600 of the sensing device 50.

The pressure plate 631 extends from the upper part of the support plate 632 in a bent shape. The pressure plate 631 may be formed integrally with the support plate 632. The pressure plate 631 may be formed of a thin plastic plate or a thin metal plate. For reference, only the pressure plate 631 may be formed of a thin plastic plate or a thin metal plate, and the support plate 632 may be formed of a material without elasticity.

The pressure plate 631 of the pressure frame 630 is exposed to the inside of the upper case 500 through the pressure hole 502 of the upper case 500 formed in the sensing device 50. The shape of the pressure plate 631 changes due to the tightening of the strap (S) when the subject breathes and the chest expands. The change in shape of the pressure plate 631 means that the pressure plate 631 is bent toward the lower case 600 due to the tightening of the strap (S). Since the pressure plate 631 is made of an elastic material, when the subject's chest is contracted, the tightness of the strap (S) is relieved and restored to its original position.

A strain sensor 633 is attached to a portion of the pressure plate 631 of the pressure frame 630. The strain sensor 633 measures the change in shape of the pressure frame 630 (i.e., the pressure plate 631) due to the tightening of the strap (S) and transmits it to the circuit board 610.

The strain sensor 633 may be attached to the lower surface of the pressure plate 631 or the upper surface of the pressure plate 631. The strain sensor 633 may be formed in a size corresponding to the entire surface of the pressure plate 631, or may be formed in a size corresponding to a portion of one surface of the pressure plate 631. The strain sensor 633 may be replaced with a strain gauge. The operation of the pressure plate 631 and the strain sensor 633 and the mounting method of the pressure frame 630 described above operate in the same manner as in Example 1.

The external ECG module 52 (electrocardiogram) is selectively connected to the sensing device 50. The external ECG module 52 is attached to the subject's body, that is, the arm, leg, or abdomen of the subject, and records the action current according to the contraction of the heart as a curve.

The external ECG module 52 may be connected to an interface circuit (not shown) provided on the first circuit board 610 through an extension cable 53. At this time, the extension cable 53 is connected to an external connection terminal (not shown) connected to an interface circuit (not shown). If the external ECG module 52 is wirelessly connected to the interface circuit, an external connection terminal may not be provided.

The external ECG module 52 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 610 through one extension cable 53. .

A bottom plate 603 is provided at the bottom of the lower case 600 of the sensing device 50.

A first sensing hole 605 is formed in a portion of the bottom plate 603 of the lower case 600. For example, the first sensing hole 605 may be formed at the center of the bottom plate 603. The first sensing hole 605 formed in the bottom plate 603 communicates with the outside of the bottom plate 603 (diaphragm 640 side) and the inside of the lower case 600 with the bottom plate 603 as the reference.

A fastening protrusion 604 for fastening the diaphragm 640 is formed around the outer side (i.e., the side facing the subject) of the bottom plate 603 of the lower case 600. The end of the fastening protrusion 604 may protrude outward to facilitate fastening of the diaphragm 640.

The diaphragm 640 is mounted on the fastening protrusion 604 to cover the entire bottom plate 603 of the lower case 600. At this time, the diaphragm 640 is mounted at a predetermined distance from the bottom plate 603 of the lower case 600. In this way, when the diaphragm 640 is mounted to be spaced apart from the bottom plate 603 of the lower case 600 at a predetermined interval, a transition space is formed 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 a 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 sound of the subject transmitted by deformation of the diaphragm 640 is It is amplified as it passes through the transition space (R) between the diaphragm 640 and the bottom plate 603. The degree of amplification 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 heartbeat sound is input to the auscultation sensor 842 provided on the first circuit board 610 through the first sensing hole 605. For reference, the auscultation sensor 842 is provided at a position corresponding to the first sensing hole 605 on the first circuit board 610. In addition, a transition hole (not shown) connecting the first sensing hole 605 and the auscultation sensor 842 may be further formed in the first circuit board 610. The transition hole may be formed with the same diameter or a smaller diameter than the first sensing hole 605.

The diaphragm 640 may be formed in a shape and material that further amplifies the wavelength region representing the heartbeat of the subject. For example, the diaphragm 640 is formed in the form of a thin rubber film and may be provided with a flat plate, a convex lens bulging toward the subject, or a dome-shaped flexible plate.

A sealing pad 660 may be further provided between the bottom plate 603 of the lower case 600 and the circuit board 610.

The sealing pad 660 is in close contact with the bottom plate 603 of the lower case 600 and the first circuit board 610 to prevent heartbeat sounds from leaking out.

The sealing pad 660 has a second sensing hole 661 with a smaller diameter than the first sensing hole 605 formed in the bottom plate 603 of the lower case 600 at a position corresponding to the first sensing hole 605. is formed For reference, if a transition hole is formed in the circuit board 610, the transition hole may be formed to have the same diameter or a smaller diameter than the second sensing hole 661.

It is possible to amplify only sounds of a desired wavelength by adjusting the diameters of the first sensing hole 605 and the second sensing hole 661. For example, since the auscultation sensor 842 measures even minute sounds, noise is also measured in addition to the subject's heartbeat. By adjusting the diameters of the first sensing hole 605 and the second sensing hole 661, 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 842. The diaphragm 640 and auscultation sensor 842 described above may operate in the same manner as in Example 1.

FIG. 13 is a cross-sectional view of the computing device 70 shown in FIG. 11.

Referring to FIGS. 11 and 13 , the computing device 70 is fastened to the strap S and is arranged to be spaced apart from the sensing device 50 . The computing device 70 is equipped with a battery 620 that supplies power to the sensing device 50 and a counting circuit that measures the breathing rate or heart rate through a measurement signal from the sensing device 50.

The computing device 70 includes an upper case 700 and a lower case 800.

The upper case 700 of the computing device 70 has a pair of fastening holes 710 formed on the side of the upper case 700 for fastening the strap S. The strap (S) penetrates across the interior of the upper case (700) through a pair of fastening holes (710). The upper part of the upper case 700 is shown closed so that the strap S is not visible, but it may be formed open so that the strap S is visible.

The lower case 800 of the computing device 70 is coupled to the lower part of the upper case 700 of the computing device 70. The lower case 800 of the computing device 70 has a second circuit board 810 mounted therein.

An electric circuit is formed on the second circuit board 810 to connect the battery 820 and a counting circuit (not shown).

The lower case 800 has a charging hole 802 formed on the side. The charging hole 802 is a hole through which a charging cable for charging the sensing device 70 passes.

The lower case 800 of the computing device 70 has a communication penetration hole 802 formed on the side through which the power communication line 51 passes. The power communication line 51 is connected to the communication terminal 812 of the second circuit board 810 through the communication through-hole 802.

The battery 820 may supply power to the first circuit board 810 through the power communication line 71. The battery 820 can be supplied with power through wired charging or wireless charging, and when supplied with power through wireless charging, the second circuit board 810 may be further equipped with a wireless charging module. When the battery 820 is charged by wire, a charging hole 802 through which the charging cable passes may be formed on the side of the lower case 800 of the computing device 70. The charging cable passes through the charging hole 802 and is connected to the charging terminal 812 formed on the circuit board 810.

The counting circuit calculates the respiratory rate using the measurement signal from the strain sensor 633.

For example, when the subject inhales during breathing, the chest expands, which tightens the strap (S) and presses the pressurizing frame (630). Also, when the subject exhales during breathing, the chest contracts, which causes the strap (S) to relax and the force pressing the pressurizing frame (630) to weaken. The strain sensor 633 attached to the pressurizing frame 630 measures the change in shape of the pressurizing frame 630 due to the subject's breathing.

The counting circuit calculates the number of breaths per minute using the peak value and the next peak value of the breathing waveform measured by the strain sensor 633.

The heartbeat sound transmitted by deformation of the diaphragm 640 of the sensing device 50 is amplified while passing through the transition space (R) (transient space) between the diaphragm 640 and the bottom plate 603. The heart beat sound is measured by the auscultation sensor 842 through the first sensing hole 605 formed in the bottom plate 603 of the lower case 600. The counting circuit 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 842.

A communication circuit (not shown) transmits at least one of the breathing rate or heart rate calculated by the counting circuit to an external device. The external device may be a diagnostic system 40 or an analysis device, and the diagnostic system 40 or an analysis device may determine an abnormal state of the subject through the subject's heart rate or respiratory rate.

Meanwhile, the second circuit board 810 of the computing device 70 may further include a diagnostic circuit (not shown).

The diagnostic circuit can determine the abnormal state of the subject through the subject's heart rate, respiratory rate, or electrocardiogram measured in the counting circuit. For example, the diagnostic circuit 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 may determine that an abnormal condition has occurred if the subject's heart rate or breathing rate is irregular.

The communication circuit transmits the information determined by the diagnostic circuit to an external device.

One of the computing device 70 or the sensing device 50 may further be equipped with a temperature sensor (not shown). Here, the external temperature refers to the temperature of the laboratory where the test of the subject is performed. The diagnostic circuit 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. The temperature sensor may be provided on the second circuit board 610 even when a diagnostic circuit is not provided, and in this case, the measured value of the temperature sensor may be transmitted to an external device through a communication circuit (not shown).

Figure 14 is a schematic diagram showing the diagnostic system of Example 5 of the present invention.

Since the counting circuit, second circuit board, and battery are the same as those of Embodiment 4, duplicate descriptions will be omitted.

The calculation device 90 may be equipped with a communication circuit that transmits the breathing rate calculated in the counting circuit to the outside.

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

The communication circuit may support at least one of wireless and wired communication. The computing device 90 may optionally be connected to an external device through wireless or wired communication.
