[First Embodiment]

Hereinafter, the respiratory diagnosis apparatus 10 using the pogo pin 130 according to the first embodiment of the present invention will be described in detail with reference to the drawings.

1 is a perspective view illustrating a respiratory diagnosis device 10 using a pogo pin 130 according to a first embodiment of the present invention.

Referring to FIG. 1 , the diagnostic apparatus 10 of this embodiment is worn on the body of a test subject so that the pogo pin 130 contacts the chest of the test subject by a wearable band 104, and the test subject During breathing, the shape change of the elastic support plate 120 due to the movement of the pogo pin 130 is measured by the pressure sensor 110. Further, the diagnostic device 10 determines a breathing pattern of the subject based on the measurement signal of the pressure sensor 110 to calculate the respiratory rate or diagnose an abnormal state of the subject.

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

During inspiration, intercostal muscles contract to lift the ribs, and the diaphragm also contracts to decrease, 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.

In this embodiment, the wearable band 104 connected to the diagnosis device 10 may be implemented in the form of a band so as 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 wearable band 104 to facilitate putting on and taking off the wearable band 104 . The wearable band 104 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.

The subject to be described below may be an animal that is difficult to wear and attach various equipment used for humans during surgery.

FIG. 2 is an exploded perspective view showing the diagnostic device 10 illustrated in FIG. 1 , FIG. 3 is a cross-sectional view showing a pogo pin 130 of the diagnostic device illustrated in FIG. 1 , and FIG. 4 is a pogo illustrated in FIG. 2 . It is a cross-sectional view showing the deformation of the pressure sensor according to the movement of the pin 130.

2 to 4, the diagnostic device 10 of this embodiment includes a housing 100, a pogo pin 130 mounted on the bottom surface of the housing 100, and a pogo pin. 130 and an elastic supporting plate 120 mounted to be connected to the bottom surface 102 of the housing, a pressure sensor 110 and an analyzer 140. And further includes a communicator 150.

The housing 100 forms the outer shape of the diagnostic device 10, is open in one direction, and has a PCB board 141 mounted with electronic devices such as the analyzer 140 and the communicator 150 mounted therein. The PCB substrate 141 may further include an interface module (not shown) for supplying power or a battery (not shown) for accumulating the supplied power. A surface of the housing 100 opened by the case 103 may be sealed. In this embodiment, the housing 100 may be integrally formed with the case 103 without the case 103 being provided separately.

A through hole 105 is formed in the bottom surface 102 of the housing 100 in contact with the object under test. The through hole 105 is for mounting the pogo pin 130. A plurality of through holes 105 may be formed in all directions based on the center of the bottom surface 102 or the center of the bottom surface 102, and in this embodiment, they are formed at corners of the bottom surface 102 of the housing 100. explain with an example.

Holders 101 to which the wearable band 104 is fastened are formed at both outer ends of the housing 100 . The holder 101 may have a fastening hole (not shown) through which the wearable band 104 passes and can be tied, or may be formed in a ring (not shown) shape through which the wearable band 104 can be hung. The shape of the holder 101 is not limited to any one.

The pogo pin 130 is formed in a pin shape and is mounted in the through hole 105 so that one end protrudes toward the object to be inspected and the other end protrudes toward the inside of the housing 100 . One end of the pogo pin 130 moves toward the inside of the housing 100 during inspiration (expansion of the chest) according to the breathing of the subject, and one end moves back to its original position during expiration (contraction of the chest). At this time, when one end of the pogo pin 130 moves in the inner direction of the housing 100, the other end of the pogo pin 130 is also moved in the inner direction of the housing 100 by the same amount of movement as the one end.

The pogo pin 130 further includes a first prevention piece 131 , a second prevention piece 132 and a spring 133 .

The first prevention piece 131 has a cross-sectional area larger than that of the through-hole 105, and the bottom surface 102 of the housing 100 is formed at a portion where the pogo pin 130 protrudes toward the inside of the housing 100. It is formed to protrude from the outer circumferential surface of the pogo pin 130 at a position adjacent to . The first prevention piece 131 restricts the pogo pin 130 from being completely separated outward from the housing 100 .

The second prevention piece 132 has a larger cross-sectional area than the through-hole 105, and the bottom surface 102 of the housing 100 is formed at a portion where the pogo pin 130 protrudes outward from the housing 100. It is formed to protrude from the outer circumferential surface of the pogo pin 130 at a position adjacent to . The second prevention piece 132 prevents the pogo pin 130 from being completely inserted into the housing 100 . That is, the pogo pin 130 moves along the through hole 105 by the distance between the first and second prevention pieces 131 and 132 .

The spring 133 is mounted on the outer circumferential surface of the pogo pin 130 between the outer side of the bottom surface 102 of the housing 100 and the second prevention piece 132 . When the pogo pin 130 is moved toward the inside of the housing 100, the spring 133 is pressed and compressed by the second prevention piece 132, and expands to restore the pogo pin 130 to its original position.

For example, when the chest of the test subject expands during inhalation, the pogo pin 130 is moved toward the inside of the housing 100 and the spring 133 is compressed at this time. When the chest is contracted during exhalation of the subject, the pogo pin 130 is restored to its original position by the expansion of the spring 133 .

The elastic support plate 120 is formed of a material having elasticity, one end is fixedly attached to the bottom surface 102 of the housing 100, and the other end is disposed at a position corresponding to the other end of the pogo pin 130 so that the pogo pin As the 130 moves, the external shape is deformed.

The elastic support plate 120 has a first surface 121, a second surface 122 and a third surface 123, and each surface is connected to the adjacent surface to be bent at a predetermined angle.

For example, the first surface 121 is disposed at the end of the pogo pin 130 protruding toward the inside of the housing 100, and the third surface 123 is fixed to the bottom surface 102 of the housing 100. Connected. And the second surface 122 connects the first surface 121 and the third surface 123. And since the height of the first surface 121 and the height of the third surface 123 are different, the second surface 122 is inclined.

Describing the operation of the elastic support plate 120, when the pogo pin 130 is moved toward the inside of the housing 100 as shown in FIG. push up At this time, since the third surface 123 of the elastic support plate 120 is fixed to the bottom surface 102 of the housing 100, external deformation and stress are generated on the second surface 122. When the pogo pin 130 is restored to its original position, the first surface 121 and the second surface 122 are also restored to their original positions by the elastic force of the elastic support plate 120 .

The pressure sensor 110 (strain gage) is formed in a polygonal or circular film type and is attached to one surface of the elastic support plate 120, the shape of which is deformed by the movement of the pogo pin 130 according to the subject's respiration. Measure the amount of displacement and stress of (120).

In this embodiment, the pressure sensor 110 may include any one of an absolute pressure sensor, a gauge pressure sensor, and a differential pressure sensor.

In this embodiment, a strain gauge is used as the pressure sensor 110, but other types of pressure sensors may be used.

The strain gauge employed in this embodiment is a gauge attached to the surface of a structure in order to measure the state and amount of deformation of the structure. The pressure sensor 110 uses a piezoelectric material whose electrical characteristics change due to internal polarization when pressure (or stress) is applied, and generates a signal using the principle that electrical resistance changes when an external force is applied and deformed.

The analyzer 140 diagnoses the subject's respiration based on the measurement signal of the pressure sensor 110 that measures the amount of displacement (change in shape) of the elastic support plate 120 caused by the movement of the pogo pin 130. Here, diagnosing the subject's breathing means diagnosing the subject's respiratory rate and abnormal condition (eg, lung disease).

For example, when contraction and expansion of the thorax due to respiration of the test subject occur, deformation of the outer shape of the elastic support plate 120 occurs due to the movement of the pogo pin 130 . For example, when the chest of the test subject is inflated, the pogo pin 130 moves toward the inside of the housing 100 and pushes up the elastic support plate 120, and when the chest of the test subject is contracted, the pogo pin 130 is originally While being restored to the position of the elastic support plate 120 is also restored to the original state.

The pressure sensor 110 measures the amount of displacement of the elastic support plate 120 according to the breathing of the subject, and the analyzer 140 determines a breathing pattern having a specific cycle from the measurement signal of the pressure sensor 110. Then, the analyzer 140 analyzes the pattern to calculate the respiratory rate of the subject and diagnose abnormal conditions.

In the present invention, the 'abnormal state' of the lungs may be defined in advance by various criteria.

For example, in the case of pulmonary edema caused by fluid filling in the lungs, when the lungs are filled with fluid above a predetermined standard, an irreversible serious situation occurs, so it is very important to detect precursor symptoms in advance.

Therefore, if the analyzer 140 of the present invention calculates that the respiratory cycle (respiratory rate) exceeds 20% of the normal state, it is regarded as a prognostic stage of an irreversible serious state and judged as an 'abnormal state' or severe 'pulmonary edema'. can judge here. Pre-stored information (respiratory cycle or respiratory rate in a normal state) of the subject may be used as an object for comparison and determination of the respiratory cycle (respiratory rate).

That is, when the test subject is a companion animal, construction data on a normal respiratory cycle may be used according to the species, male/female, age and weight of the companion animal.

If there is no pre-stored respiratory period for the subject, an average respiratory period for a predetermined time period for the subject may be used.

In this embodiment, the analyzer 140 may calculate the respiratory rate of the subject or diagnose an abnormal condition in consideration of a measurement signal different from the measurement signal of the pressure sensor 110 .

For example, a stethoscope sensor (not shown) may also be mounted on the analyzer 140 . The respiratory rate of the subject may be calculated or an abnormal state may be diagnosed by considering both the biosignal measured through the auscultation sensor (not shown) mounted in the diagnosis device 10 and the measurement signal of the pressure sensor 110 . Here, the biosignal includes a heart sound signal and a respiration signal, and diagnosis accuracy can be increased by considering both the biosignal and the measurement signal of the pressure sensor 110 .

The communicator 150 transmits information diagnosed by the analyzer 140 to the outside. Here, the external may include a laptop computer, a terminal, a tablet PC, a diagnosis server, and a smart phone through which a practitioner can check information measured by the diagnosis device 10 .

The communicator 150 uses Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, Wireless Sensor Network (WSN), Wireless LAN or WLAN (Wireless LAN or Wi-Fi) and UWB (Ultra Wideband), or short-distance wireless communication or low-power wide area (LPWA) long-distance communication may be supported. In particular, the communicator 150 may support broadcasting-type information transmission by supporting a Bluetooth-based BLE beacon protocol. In addition, the communicator 150 may support mobile communication protocols such as 2G, 3G, 4G, and 5G, wireless broadband (Wibro), world interoperability for microwave access (Wimax), and high speed downlink packet access (HSDPA). may be

In this embodiment, if the communicator 150 is not provided, the diagnosis device 10 may further include a display screen (not shown) for outputting diagnosis results.

5 is a diagram showing a pattern of respiration measured by the pressure sensor 110 of this embodiment.

Referring to FIG. 5 , the signal measured by the pressure sensor 110 has a pattern having a specific cycle according to the subject's respiration.

For example, if the measurement signal has a regular pattern as shown in area (A) of FIG. 5, the contraction and expansion of the chest are determined to be regular, and the analyzer 140 considers that the subject is breathing normally. In addition, the analyzer 140 calculates the subject's breathing by counting the period of the pattern.

The analyzer 140 diagnoses that an abnormal state of the lungs (eg, lung disease) has occurred when the measurement signal has an irregular pattern as shown in area (B) of FIG. 5 .

The analyzer 140 may determine a specific lung disease name by comparing the pattern of the measurement signal with various predefined lung disease patterns.

6 is a graph showing breathing patterns according to various types of respiratory symptoms.

Referring to FIG. 6, normal breathing (eupnea), tachypnea, bradypnea, apnea, cheyne stokes, biots, and moribund breathing. Waveforms such as agonal, shallow, hyperpnea, kussmauls and sighing are derived differently.

Therefore, the analyzer 140 compares the similarity with the waveform for each respiratory symptom based on the respiratory waveform measured from the subject, and when a waveform with a predetermined similarity or higher exists, the type of lung disease of the corresponding respiratory symptom can be specifically determined.

[Fifth Embodiment]

12 is a flowchart illustrating a method for diagnosing respiration of a diagnosis server excluding humans according to a fifth embodiment of the present invention.

The subject to be described below may be an animal that is difficult to wear and attach various equipment used for humans during surgery.

In addition, since the measurement device described below is the same as the measurement device of the third embodiment, redundant description is omitted.

Referring to FIG. 12 , the respiration diagnosis method of the present embodiment includes receiving a measurement signal (S100) and determining a respiration rate or a respiration pattern (S200).

In the step of receiving the measurement signal (S100), the receiver receives a measurement signal for external deformation of the elastic support plate generated when the subject breathes from the measurement device.

The receiver connects the communication device of the measurement device with Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, Wireless Sensor Network (WSN), and Wireless Sensor Network (WLAN). Data is transmitted and received through short-distance wireless communication such as LAN or Wifi and UWB (Ultra Wideband) or long-distance communication such as Low Power Wide Area (LPWA). In particular, data can be transmitted and received through broadcasting-type information transmission by supporting the Bluetooth-based BLE beacon protocol. In addition, the communicator and receiver transmit data through mobile communication protocols such as 2G, 3G, 4G, and 5G, Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), and HSDPA (High Speed Downlink Packet Access). can send and receive.

In this embodiment, the communicator and the receiver may transmit and receive data in a wired manner through a cable.

The analyzer in the step of determining the breathing rate or breathing pattern (S200) determines the breathing pattern based on the measurement signal of the pressure sensor that measures the amount of displacement of the elastic support plate by the movement of the pogo pin, and determines the breathing pattern through the breathing pattern. Respiratory rate and abnormal conditions (eg lung disease) are diagnosed.

For example, when the chest is contracted or expanded due to respiration of the test subject, the shape of the elastic support plate is also deformed due to the movement of the pogo pin. For example, when the chest of the test subject expands, the pogo pin pushes up the elastic support plate, and when the chest of the test subject contracts, the pogo pin and the elastic support plate are restored to their original states.

The pressure sensor measures the amount of displacement of the elastic support plate by the movement of the pogo pin, and the analyzer determines a breathing pattern having a specific cycle from the received measurement signal of the pressure sensor. Then, the analyzer analyzes the pattern to calculate the respiratory rate of the subject and diagnose abnormal conditions.

In the present invention, the 'abnormal state' of the lungs may be defined in advance by various criteria.

For example, in the case of pulmonary edema caused by fluid filling in the lungs, when the lungs are filled with fluid above a predetermined standard, an irreversible serious situation occurs, so it is very important to detect precursor symptoms in advance.

Therefore, if the analyzer of the present invention calculates that the respiratory cycle (respiratory rate) exceeds 20% of the normal state, it can be regarded as a precursor to an irreversible serious condition and judged as an 'abnormal condition' or serious 'pulmonary edema'. there is. here. Pre-stored information (respiratory cycle or respiratory rate in a normal state) of the subject may be used as a comparative judgment target for the respiratory cycle (respiratory rate).

That is, when the test subject is a companion animal, construction data on a normal respiratory cycle may be used according to the species, male/female, age and weight of the companion animal.

If there is no previously stored respiratory cycle for the subject, an average respiratory cycle for a predetermined time of the subject may be used.

In this embodiment, the analyzer may calculate the respiratory rate of the subject or diagnose an abnormal condition by considering a measurement signal different from the measurement signal of the pressure sensor.

For example, a stethoscope sensor (not shown) may also be mounted on the analyzer. The respiratory rate of the subject may be calculated or an abnormal state may be diagnosed in consideration of both the vital signal measured through an auscultation sensor (not shown) mounted in the diagnosis device and the measurement signal of the pressure sensor. Here, the bio-signal includes a heart sound signal and a respiration signal, and diagnostic accuracy can be increased by considering both the bio-signal and the measurement signal of the pressure sensor.

Although the above has been described with reference to several embodiments of the present invention, those skilled in the art can make the present invention within the scope not departing from the spirit and scope of the present invention described in the claims below. It will be appreciated that various modifications and variations may be made.
