Description

Cardiopulmonary function measuring device and system {DEVICE AND SYSTEM FOR MEASURING CARDIOPULMONARY DYSFUNCTION}

The present invention relates to a device and system for measuring cardiorespiratory function, and more particularly, measures a change in pressure inside the device according to respiration and heartbeat of a subject, and counts the heart rate and respiration of the subject based on the measured pressure signal waveform. The present invention relates to a cardiorespiratory function measuring device and system for diagnosing the cardiopulmonary function of a subject by considering one of the external temperature and the external temperature.

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 confirmed through an auscultation sensor, but when confirmed through an auscultation sensor, since other noises are collected together, a filter for removing noise must exist.

In addition, since both a sensor for sensing respiration and a sensor for sensing heart sound must be provided to simultaneously measure heart and breath sounds, a stethoscope equipped with both of these sensors is expensive. In addition, the internal structure of the stethoscope is 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.

In particular, in animals, to measure body temperature that is proportionally interlocked with external temperature, it is necessary to measure body temperature in the rectum, but it is very difficult to measure body temperature in organs. Since the body temperature measured by body surface measurement, corneal measurement, and infrared measurement other than the rectum does not correlate proportionally with the external temperature, it is difficult to accurately determine the cause of the increased temperature in temperature measurement.

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.

[First Embodiment]

A first embodiment relates to a device for measuring pressure change and external temperature according to respiration and heartbeat of a subject.

Hereinafter, a cardiorespiratory function measurement device according to a first embodiment of the present invention will be described in detail with reference to the drawings.

1 is a schematic diagram of a cardiorespiratory function measurement device according to a first embodiment of the present invention.

Referring to FIG. 1, the measuring device 10 of the first embodiment is worn on the body of a subject by a wearable band 103, and the protruding structure 121 changed according to the subject's respiration and heartbeat. A pressure change inside the measuring device 10 and an external temperature due to the shape change are measured. The waveform of the pressure change inside the measurement device 10 measured as described above may be derived as a heartbeat waveform and a breathing waveform of the subject, respectively, and the heartbeat waveform and the breathing waveform are used to diagnose the heart function and lung function of the subject. Heart rate and respiratory rate can be derived for

The external temperature is used to determine whether an increase in respiration or heart rate of the subject is caused by an abnormal symptom (eg, disease) or external temperature.

Animals such as dogs (including puppies), cats, and birds do panting respiration in which they breathe by sticking out their tongues to control their body temperature when the outside temperature rises above the proper temperature because sweat glands are not developed. Moisture evaporation is promoted by the airways or airways, and a large amount of heat is lost, regulating body temperature. And even if the external temperature of animals such as dogs (including dogs), cats and birds is lower than the appropriate temperature, the metabolism is affected, and the body temperature is taken away by the cold air, so respiration and heart rate increase.

That is, 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 is an abnormal condition (e.g., For example, it is important to determine whether it is caused by disease or external temperature. For example, an external temperature in a normal range, that is, an appropriate temperature range that does not significantly affect the determination of an abnormal state is referred to as room temperature in technical terms.

In the first embodiment, the wearable band 103 connected to the measuring device 10 is

It may be implemented in the form of a band so that it can be worn on a subject. Members such as buckles (not shown), snap buttons (not shown), or Velcro (not shown) are provided at both ends of the wearable band 103 to facilitate putting on and taking off the wearable band 103 . The wearable band 103 is implemented to have elasticity or to be adjustable in length, so that it can provide a comfortable fit according to the body shape of the subject.

Figure 2a is an exploded perspective view showing the measuring device 10 illustrated in Figure 1,

FIG. 3A is a cross-sectional view of the measuring device 10 illustrated in FIG. 1 , and FIG. 3B is a cross-sectional view of an example in which the protruding structure 121 according to the first embodiment is deformed due to expansion of the chest.

Referring to FIGS. 2A, 3A, and 3B, the measuring device 10 of the first embodiment includes a housing 110, a base plate 120, and a substrate 130. .

The housing 110 is attached to the body of the subject by a wearable band ( 103 in FIG. 1 ). The housing 110 has an empty interior, one surface facing the object under examination is open, and the bottom plate 120 is coupled to the open surface.

At both ends of the housing 110, fastening structures 111 for fastening the wearable band (103 in FIG. 1) are formed. The shape of the fastening structure 111 is not limited to any one. For example, the fastening structure 111 may be formed in a ring shape on which a wearable band can be hung.

The bottom plate 120 (base plate) is coupled to one surface of the housing 110 and comes into contact with the test subject. The bottom plate 120 may be provided with a protruding tip 124 for coupling with the housing 110 on the outside, and the protruding tip 124 is fitted into a fixing groove (not shown) of the housing 110. can be combined The coupling method of the bottom plate 120 and the housing 110 is not limited to any one.

The protruding tip 124 formed on the bottom plate 120 also serves to fix the substrate 130, the sealing pad 140, and the cover plate 150 mounted inside the housing 110 inside the housing 110. can do.

The protruding structure 121 is provided on a part of the bottom plate 120 . The protruding structure 121 is preferably disposed at the center of the bottom plate 120 .

The protruding structure 121 may be formed in the form of a thin film having elasticity or a partition plate, and may be made of ABS, PC, PE, PET, POM, PP, natural rubber, synthetic rubber, silicone, TPU, or the like. .

The protruding structure 121 provided on the bottom plate 120 directly contacts the subject and changes shape according to respiration and heartbeat of the subject. For example, when the chest of the subject expands due to respiration and heartbeat, the protruding structure 121 contracts toward the inside of the housing 110 (see FIG. 3B ), and conversely, when the chest of the subject contracts, the protruding structure 121 ) is restored to its original state.

In order to respond sensitively to changes in the chest of the subject, the protruding structure 121 is formed to protrude from the bottom plate 120 toward the measurement site of the subject. At this time, the protruding structure 121 protrudes from the bottom plate 120 and may be formed in a flat shape.

For example, as shown in FIG. 2B, a through hole 121a is formed in the bottom plate 120, and the protruding structure 121 is bonded to the outer circumferential surface of the through hole 121a, so that the bottom plate 120 and the protruding structure 121 ) may be combined.

As another example, as shown in FIG. 4 , the protruding structure 121 protrudes from the bottom plate 120 and may be formed in a convex lens or dome shape. The protruding structure 121 and the bottom plate 120 may be integrally formed by injection molding. In this case, the protruding structure 121 may be formed to be relatively thinner than the surrounding area, and the peripheral area may be coupled with the housing 110 and formed with a degree of rigidity or thickness capable of withstanding an external force.

A substrate 130 is mounted inside the housing 110 . A pressure sensor 132, a temperature sensor 133, and various modules and circuits may be mounted on the substrate 130. In addition, a battery (not shown) for driving the measuring device may be provided on the substrate 130, and a charging terminal (not shown) for charging the battery may also be installed.

The pressure hole 131 is formed on a part of the substrate 130 . The pressure hole 131 is for transmitting pressure (eg, air pressure) due to a shape change of the protruding structure 121 to the pressure sensor 132 .

The pressure sensor 132 is disposed on the substrate 130 at a position in contact with the pressure hole 131 . In the first embodiment, the pressure hole 131 may be formed in the center of the substrate 130 . The position of the pressure hole 131 may be formed at another position even if it is not the center of the substrate 130 .

The pressure sensor 132 measures a change in pressure inside the housing 110 due to a change in shape of the protruding structure 121 according to respiration and heartbeat of the subject. The waveform of the pressure change inside the housing 110 measured as described above may be analyzed or collected as a heartbeat waveform, a breathing waveform, and a heartbeat waveform of the subject, and the heartbeat waveform and the breathing waveform are derived from the heartbeat and respiration rate of the subject. It can be used to diagnose cardiac and pulmonary function.

The temperature sensor 133 is mounted inside the housing 110 to measure the external temperature. The temperature sensor 133 measures the room temperature of a examination room, diagnosis room, or operating room where a subject is placed for examination or surgery. Although the drawing shows that the temperature sensor 133 is installed inside the housing 110, it may be installed outside the housing 110.

In this specification, the pressure sensor 132 and the temperature sensor 133 are only logically separated, and may be implemented in the form of an integrated sensor in an integrated element such as MEMS (Micro Electro-Mechanical Systems). MEMS (Micro Electro-Mechanical Systems) means 'microelectro-mechanical systems', and MEMS sensors are ultra-small and highly sensitive sensors that are used as tools for monitoring, detecting, and monitoring the external environment through physical, chemical, and biological sensing. .

The measuring device may further include a cover plate 150 and a sealing pad 140 .

The cover plate 150 covers the protruding structure 121 formed portion located inside the bottom plate 120 to form a pressure space 123 in the space between the cover plate 150 and the protruding structure 121. do.

The cover plate 150 is mounted in the mounting space 122 formed on the outer circumferential surface of the protruding structure 121 . The outer circumferential surface of the cover plate 150 is disposed in close contact with the mounting space 122 of the protruding structure 121 . The outer circumferential surface of the cover plate 150 is bonded to the mounting space 122 of the protruding structure 121 so that it can be completely adhered to, but in order to simplify the manufacturing process and reduce the cost of the bond material, the sealing pad 140 described below Through this, it can be in close contact with the mounting space 122 of the protruding structure 121.

A first pressure transfer hole 151 is formed in a part of the cover plate 150 . The first pressure transition hole 151 serves to transfer pressure (eg, air pressure) due to a shape change of the protruding structure 121 toward the pressure hole 131 of the substrate 130 .

It may be preferable that the first pressure transition hole 151 is formed at the center of the cover plate 150 .

A sealing pad 140 is disposed between the substrate 130 and the cover plate 150 . The sealing pad 140 is to prevent a close contact between the cover plate 150 and the protruding structure 121 from spreading due to pressure due to a shape change of the protruding structure 121 . The sealing pad 140 presses the cover plate 150 toward the protruding structure 121 between the substrate 130 and the cover plate 150 while maintaining a gap between the protruding structure 121 and the cover plate 150. .

The rod pad 140 may be formed of a silicon material, but is not limited thereto. For example, the sealing pad 140 may be formed of various materials such as rubber, polyurethane, polycarbonate, and polyamide.

A second pressure transfer hole 141 is formed in a portion of the sealing pad 140 at a position corresponding to the first pressure transfer hole 151 of the cover plate 150 . The second pressure transition hole 141 transfers pressure (eg, air pressure) transmitted through the first pressure transition hole 151 to the pressure hole 131 of the substrate 130 . The second pressure transition hole 141 is connected to the pressure hole 131 formed in the substrate 130 .

The pressure hole 131 formed in the substrate 130 may have a smaller diameter than the first pressure transition hole 151 and the second pressure transition hole 141 . Since the pressure hole 131 formed in the substrate 130 has a smaller diameter than the first pressure transition hole 151 and the second pressure transition hole 141, the pressure by the protrusion structure 121 is applied to the substrate 130. It is possible to concentrate the pressure into the pressure hole 131, so that the sensitivity of the pressure sensor 132 can be improved.

The measuring device 10 may not include the cover plate 150 and the sealing pad 140 . In this case, the substrate 130 may be bonded to the protruding structure 121 to secure sealing force. In addition, the measuring device 10 may not include only the sealing pad 140, and in this case, the cover plate 150 may be bonded to the protruding structure 121 to secure sealing force.

A bottom plate (not shown), a protruding structure 410, a substrate (not shown), a pressure sensor 420, a temperature sensor 430, and a sealing pad (not shown) of the measuring device 40 described in the fourth embodiment. And a cover plate (not shown) includes a bottom plate (not shown), a protrusion structure 310, a substrate (not shown), a pressure sensor 320, a temperature sensor 330, a sealing pad (not shown), and a cover plate (not shown) of the third embodiment. Since it is the same as the cover plate (not shown), redundant descriptions will be omitted, and only the calculation module 440, the diagnosis module 450, and the communication module 460 will be described.

Referring to FIGS. 10 and 11A , the measuring device 40 further includes a calculation module 440 and a diagnosis module 450 .

The calculation module 440 is a signal waveform (FIG. 11A (C)) measured by the pressure sensor 410, a heartbeat waveform (FIG. 11A (A)) derived from the signal waveform, and a breathing waveform (FIG. 11A (B) )) to obtain The peak value change due to the deformation of the protruding structure 121 is recorded in the signal waveform obtained by the calculation module 440 and the heartbeat and respiration waveforms derived from the signal waveform.

The calculation module 440 may measure the heart rate and respiratory rate of the subject using the signal waveform (FIG. 11A(C)) measured by the pressure sensor 410, but to more easily measure the signal waveform ( 11A (C)) is separated into a heartbeat waveform (FIG. 11A (A)) and a respiration waveform (FIG. 11A (B)) through an algorithm to measure the heart rate and respiratory rate of the subject.

For example, the subject's respiration is divided into inspiration 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.

11A (A) is a heartbeat waveform derived from the signal waveform of the pressure sensor 410. As shown in (A) of FIG. 11A, the calculation module 440 calculates the heart rate per minute using the peak value of the measured heart rate waveform and the next peak value.

Figure 11a (B) is a breathing waveform derived from the signal waveform of the pressure sensor 410. As shown in (B) of Figure 11a, the calculation module 440 calculates the respiratory rate using the peak value and the next peak value of the measured respiratory waveform.

11A (C) is a signal waveform measured by the pressure sensor 410. The signal waveform is a waveform in which changes in pressure due to heartbeat and respiration of the subject are all recorded.

As shown in (C) of FIG. 11A, the calculation module 440 calculates the respiratory rate from the signal waveform using the peak value change (ie, the peak value and the next peak value) measured by the deformation of the protruding structure 121 in the heartbeat waveform. . Further, the calculation module 440 considers a section excluding the peak value (A) from the heartbeat waveform section showing a peak value due to the deformation of the protruding structure 121 as a section (B) of a general heartbeat waveform, and a section of the heartbeat waveform. Calculate the heart rate through (B).

For example, as shown in FIG. 11B, the peak value due to deformation of the protruding structure 121 when the subject's chest expands to the maximum value (section A) and the section when the chest expands to the maximum value after contraction The number of breaths is counted as a breathing interval.

In addition, the section except for when the subject's chest expands to the maximum value (section A) is regarded as a waveform caused by a general heartbeat.

11c is a diagram illustrating a process of deriving a breathing waveform from a signal waveform measured by the pressure sensor of FIG. 11a.

Referring to Figure 11c, the calculation module 440 derives the respiratory waveform from the signal waveform using an algorithm. For example, the calculation module 440 sets the central value (L1) of the moving average of the signal waveform, and adjusts the central value (L1) of the moving average of the signal waveform upward to a preset value to the respiratory moving average central value ( L2) is set. For example, the breathing moving average central value L2 may be raised to twice the central value L1 of the moving average of the signal waveform. And the calculation module 440 acquires only the waveform within a preset range based on the respiratory moving average central value (L2) to obtain the respiratory waveform (S1).

11D is a diagram illustrating a process of deriving a heartbeat waveform from a signal waveform measured by the pressure sensor of FIG. 11A.

Referring to 11d, the calculation module 440 derives the heartbeat waveform from the signal waveform using an algorithm. For example, the calculation module 440 sets the center value (L1) of the moving average of the signal waveform, adjusts the center value (L1) of the moving average of the signal waveform downward to a preset value, and adjusts the heart rate moving average center value ( L3) is set. For example, the heartbeat moving average central value L3 may be lowered to 30% of the central value L1 of the moving average of the signal waveform. Further, the calculation module 440 obtains the heartbeat waveform S2 by acquiring only waveforms within a preset range based on the heartbeat moving average central value L3.

The calculation module 440 is installed on a substrate (for example, 130 in FIG. 3A) inside the measuring device 40 or at a separate location separated from the substrate inside the measuring device 40 (for example, FIG. 3A). 170 position of) may be provided.

The diagnosis module 450 determines an abnormal state of the subject by comprehensively considering at least one of the heart rate or respiration rate of the subject calculated by the calculation module 440 and the external temperature measured by the temperature sensor 430 .

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

If at least one of the subject's heart rate or respiration rate increases or decreases despite the external temperature being within the appropriate temperature range (room temperature), it is determined that an abnormal state has occurred in the subject, and the external temperature is within the appropriate temperature range (room temperature). temperature), the increase or decrease of at least one of the heart rate or respiratory rate of the subject is determined as an increase or decrease due to external temperature.

The respiratory rate or heart rate of the subject to be tested can be confirmed from an algorithm or a pre-built DB.

The diagnostic module 450 diagnoses the heart and lung functions of the subject by comparing the heart rate and respiratory rate with pre-established heart rate and respiratory rate data, which comprehensively considers any one of the respiratory rate and the external temperature.

The communication module 460 transmits at least one of the heart rate and respiration rate calculated by the calculation module 440 and the result diagnosed by the diagnosis module 450 to an external device (eg, a monitor outputting the result or a result recording medium) send to
