Description

A wearable sensing device for animal diagnosis, a wearable diagnosis device for animals, and a biodiagnostic system for animals

The present invention relates to a wearable sensing device for animal diagnosis, a wearable diagnosis device for an animal, and a biodiagnostic system for animals, and more particularly, to simultaneously detect a biological sound and respiration of a subject, and to distinguish between heart and lung sounds without a complex algorithm. The present invention relates to a wearable sensing device for animal diagnosis, a wearable diagnosis device for animals, and a biodiagnostic system for animals, which can easily distinguish between heart and lung sounds in consideration of both biological sound and respiration.

In general, a stethoscope is used to check the health status of the examinee by listening to biological sounds generated inside the subject. A conventional stethoscope is composed of a collection unit that collects biological sounds generated from the human body, an earpiece that can listen to the collected biological sounds, and a connecting tube that connects the collection unit and the earpiece to deliver biological sounds. it is common In the conventional analog stethoscope, the doctor places the stethoscope on the body of the subject (patient, etc.) and listens to the stethoscope sound. At this time, the sound of the heart or breathing, which is the source of the sound, has a very low frequency level between 20 Hz and 800 Hz, and it is difficult to hear because it is hidden in the fat and muscle surrounding the subject and under the ribs. Furthermore, since the sound output through the stethoscope is a mixture of heart sound (heart sound) and breathing sound (lung sound), it is difficult to distinguish between heart sound and lung sound in audible signals, so highly skilled know-how is required.

In order to solve this problem, a stethoscope equipped with a scale meter, such as a hearing aid, or an electronic stethoscope equipped with an amplifier capable of measuring biological sound inside a living body even when the subject is not naked have been developed. The electronic stethoscope collects a biological sound signal generated from a subject, converts it into an electrical signal, amplifies it, and outputs it to a speaker, transmits it to an external device, or records it and then reproduces it if necessary.

On the other hand, when diagnosing an abnormal state of a subject, heart sound and lung sound must be distinguished. However, when trying to distinguish heart sound from lung sound using only the body sound of the subject, it is difficult to accurately distinguish between heart sound and lung sound, and a diagnosis error may occur. There is a disadvantage that a complex algorithm is required to accurately distinguish between heart and lung sounds.

<First embodiment>

The first embodiment relates to a device that is worn on a body of a subject and senses a biological sound and respiration of the subject.

1 is a perspective view illustrating a wearable sensing device 10 for diagnosing an animal according to a first embodiment.

Referring to FIG. 1 , the wearable sensing device 10 includes a body housing 100 in which a strap fastening part 200 on which a strap 1 is hung is formed on the outside. The wearable sensing device 10 for animal diagnosis is worn on the body of the subject by means of a strap 1, and the auscultation sensor 130 installed on one surface of the main housing 100 comes into contact with the body of the subject to make the subject's biological sound. to detect And the wearable sensing device for animal diagnosis 10 uses a strain sensor 120 that measures the amount of displacement of the side wall of the main body housing 100 that occurs due to a change in the tensile force of the strap 1 when the subject breathes. detect The wearable sensing device 10 for animal diagnosis transmits the measured values of the auscultation sensor 130 and the strain sensor 120 to the outside through a wireless communication module (not shown). Here, the external may include a diagnostic device D or a diagnostic server for diagnosing a subject. The diagnosis device H may include a smart phone or a medical-only terminal, and may communicate with the wearable sensing device 10 for diagnosing an animal using short-range wireless communication such as Bluetooth (BLU), Wifi, or Zigbee. The diagnosis apparatus H may determine the disease or abnormal state of the subject based on the measurement value of the strain sensor 120 .

The strap 1 may be implemented in the form of a band to be worn on the subject. Both ends of the band are provided with coupling members to facilitate wearing and release. As the coupling member, Velcro, a buckle, or a snap button may be used. In addition, the band can provide a comfortable fit according to the body type of the subject by being implemented to have elasticity or to be able to adjust the length.

The strap 1 may adopt a band of variously modified forms, and specific examples thereof include a belt-shaped straight band, an X-shaped band, a double band, and the like.

The strain sensor 120 detects the amount of displacement of the side wall of the main body housing 100 by the tensile force of the strap 1 to detect the respiration of the subject.

The strain sensor 120 uses a piezoelectric material whose electrical characteristics change due to internal polarization when pressure (or stress) is applied. The strain sensor 120 may include a substrate and an electrode, and the substrate and the electrode are provided inside the body housing 100 . In this embodiment, the strain sensor 120 may be replaced with a stretch sensor.

For example, respiration may be divided into inhalation and exhalation.

During inspiration, the intercostal muscles contract and the ribs are lifted, and the diaphragm also contracts as the diaphragm contracts and the volume of the thoracic cage increases. Conversely, during expiration, the intercostal muscles relax and the ribs descend, and the diaphragm relaxes and rises, reducing the volume of the chest cavity.

In the present invention, respiration may be defined in a broad sense of detecting inspiration and exhalation. Alternatively, it may mean expansion and contraction of the rib cage in a narrow sense, and may mean expansion and contraction of the lungs in a narrower sense. That is, in the present invention, the definition of respiration is interpreted as a meaning encompassing the expansion and contraction of the chest or lungs as well as a comprehensive meaning of inspiration and expiration.

In the present invention, the strain sensor 120 detects expansion and contraction of the lungs or rib cage caused by breathing of a subject, for example, a human body or a companion animal.

The wearable sensing device 10 for animal diagnosis is worn by the strap 1 surrounding the chest of the subject, and when the subject breathes, the strap 1 may be expanded or contracted according to the inhalation and exhalation. In this process, when the strap 1 is expanded or contracted, the strap fastening part 200 to which the strap 1 is connected deforms the sidewall of the main body housing 100, and the strain sensor 120 performs the test on the basis of the displacement amount of the sidewall. sense the breath of

In order for the strain sensor 120 to operate smoothly, it is recommended that the wearable sensing device 10 for animal diagnosis be worn so as to surround the lung (chest) of the subject. In addition, it is preferable to be worn with an appropriate tension within a range that does not severely compress the lungs as the subject breathes. However, it is not necessary to limit the mounting position to the lung region, and it can be mounted on any part of the body if the relaxation and contraction of the lungs can be detected. In particular, in the case of companion animals, the body itself is rather small compared to humans, so there is a difference in degree, but the relaxation and contraction of the lungs can be detected in almost all parts of the body. Therefore, it does not matter if the wearable device 100 is worn in a position other than the lungs as long as it is within the body of the companion animal.

The auscultation sensor 130 is installed on one surface of the main body housing 100 in contact with the body of the subject. The auscultation sensor 130 may be installed on one surface of the main body housing 100 while being provided inside a separate case (not shown). The case provided with the body housing 100 and the auscultation sensor 130 may be made of an aluminum material in order to increase the efficiency of the auscultation function.

The auscultation sensor 130 detects a biological sound of the subject. The biological sounds include heart sounds and lung sounds, and other sounds from organs or surrounding noises may be included.

The auscultation sensor 130 includes a tube, a microphone that converts the sound collected through the tube into an electrical signal, a signal amplifier that amplifies the electrical signal converted through the microphone, and the signal amplified by the signal amplifier. It may be configured to include an output terminal.

2 is a perspective view illustrating the main body housing 100 of the wearable sensing device 10 for animal diagnosis according to the first embodiment of the present invention, and FIG. 3 is a cross-sectional view illustrating the main body housing 100 illustrated in FIG. 2 . .

2 and 3 , the wearable sensing device 10 includes a auscultation sensor 130 , a strain sensor 120 , a body housing 100 and a strap fastening part 200 formed on the outside of the body housing 100 and It includes a wireless communication module 350 .

Since the auscultation sensor 130 and the strain sensor have been described with reference to FIG. 1 , a redundant description will be omitted.

The main body housing 100 forms the outer shape of the wearable sensing device 10 for animal diagnosis, and includes a bottom surface 101 and a sidewall formed around the bottom surface 101 . For reference, hereinafter, the bottom surface 101 of the main body housing 100 means the same surface as the one surface of the main body housing 100 in contact with the body of the subject described with reference to FIG. 1 .

2 and 3 show that the shape of the bottom surface 101 is formed in a rectangular shape, in addition to this, the shape of the bottom surface 101 may be formed in a circular or polygonal shape. For example, as shown in FIG. 4 , the bottom surface 101 may have a circular cross-section.

A hole 102 for exposing the auscultation sensor 130 is formed through the bottom surface 101 . The auscultation sensor 130 is installed in the hall 102, and if the auscultation sensor 130 is provided in a sensor-only case (not shown), the case is installed in the hall 102 for exposing the auscultation sensor 130. do.

A side wall is formed around the bottom surface 101 . When the main body housing 100 is formed of the bottom surface 101 and the side wall, the opposite surface of the bottom surface 101 is opened, and the open surface of the main body housing 100 may be closed by a cover (not shown). The cover may be selectively fastened to the body housing 100 , and a screw hole 103 for fastening with the cover may be formed inside the body housing 100 .

A pair of strap fastening portions 200 are formed on the outer side of the side wall portion facing each other of the main body housing 100 . The strap fastening part 200 is formed so that one end is connected to a portion of the side wall of the main body housing 100 , and the other end is extended to be spaced apart from the side wall of the main body housing 100 by a predetermined distance. That is, the strap fastening part 200 may be formed in a ring shape with an open end 220 . The strap ( 1 in FIG. 1 ) is fastened to the inner side 201 of the strap fastening part 200 formed in a ring shape.

In this embodiment, all of the pair of strap fastening parts 200 are illustrated as being formed in a ring shape, but only one of the pair of strap fastening parts 200 may be formed in a ring shape. If any one of the pair of strap fastening parts 200 is not formed in a ring shape and both ends are connected to the sidewall of the body housing 100, a fastening hole (not shown) for fastening the strap may be formed through. .

The strain sensor 120 is mounted on the inner surface of the point 210 to which the strap fastening part 200 is connected among the sidewall parts 110 where the strap fastening part 200 is formed. That is, when the strap fastening part 200 is formed in the form of a ring as described above, the strain sensor 120 is the opening point 220 of the strap fastening part 200 among the sidewall parts 210 where the strap fastening part 200 is formed. ) is mounted on the inner side of the side wall corresponding to the opposite point 210 . At least one of the sidewall portions 110 where the strap fastening portion 200 is formed includes a partition wall portion 112 having a first thickness and a partition wall portion 111 having a second thickness. The barrier rib portion 111 having the second thickness may have a relatively thin thickness compared to the first barrier rib portion. The partition wall part 112 of the first thickness and the partition wall part 111 of the second thickness may be divided into both sides based on the height direction of the side wall.

The second barrier rib portion 111 having a thin second thickness is formed in the side wall portion 210 connected to the strap fastening portion 200 , and the barrier rib portion 112 having a thick first thickness is formed in the strap fastening portion 200 . is formed in the open area. That is, the strap fastening part 200 has one end connected to the side wall corresponding to the partition wall part 111 of the second thickness, and the other end is extended toward the side wall corresponding to the partition wall part 112 of the first thickness to form a ring. is open

In this embodiment, the strain sensor 120 is attached to the inner wall of the barrier rib part 111 having a second thickness. The size of the strain sensor 120 is not limited to any one, and may be formed to cover the entire or part of the inner wall of the partition wall portion 111 of the second thickness.

As described above, when the sidewall of the main body housing 100 is divided into the partition wall part 112 and the partition wall part 111 of the second thickness having different thicknesses, the partition wall part 112 of the second thickness when an external force is applied to the sidewall. ), the sensitivity to the amount of displacement is increased, so it is easy to detect the amount of displacement by an external force.

In the present embodiment, a plurality of holes (not shown) may be formed in the partition wall part 112 of the first thickness and the partition wall part 111 of the second thickness. The plurality of holes formed in the partition wall part 112 of the first thickness and the partition wall part 111 of the second thickness displace the elastic sensitivity of the partition wall part 112 of the first thickness and the partition wall part 111 of the second thickness, Accordingly, the strain sensor 120 can easily measure the amount of displacement of the barrier rib part 111 of the second thickness.

In this embodiment, the strain sensor 120 is illustrated as being provided on each of the inner surfaces of the sidewalls on which the pair of strap fastening parts 200 are formed, but any of the inner surfaces of the sidewalls on which the pair of strap fastening parts 200 are formed. It may be formed only on the inner surface of one side wall (refer to FIG. 6). If the strain sensor 120 is provided only on the inner surface of any one side wall, the side wall not provided with the strain sensor 120 is divided into a partition wall part 112 of a first thickness and a partition wall part 111 of a second thickness. free of charge

A wireless communication module (not shown) is mounted inside the main body housing 100 . The wireless communication module transmits the measured values of the auscultation sensor 130 and the strain sensor 120 to the outside. Here, the external may be a diagnostic device or a diagnostic server (500 in FIG. 8 ) for determining an abnormal state of the subject based on the measured values of the auscultation sensor 130 and the strain sensor 120 .

Wireless communication modules are Bluetooth, RFID, Radio Frequency Identification, IrDA, infrared Data Association, UWB (Ultra Wideband), ZigBee, WSN (Wireless Sensor Network), WLAN (Wireless LAN or Wifi) ) and short-range wireless communication such as UWB (Ultra Wideband) can be supported. In particular, by supporting a Bluetooth-based BLE beacon protocol, it is also possible to support broadcasting-type information transmission. In addition, the communication module 140 is a mobile communication protocol such as 2G, 3G, 4G, 5G, Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access) mobile communication protocols such as may support

Looking at the operation of the wearable sensing device 10 configured as described above, when the subject breathes while the wearable sensing device 10 for animal diagnosis is worn on the subject's body, the rib cage repeats expansion and contraction.

When the rib cage of the subject expands, the strap (1 in FIG. 1) pulls the strap fastening part 200, and the strap (1 in FIG. 1) pulls the strap fastening part 200 when the subject's rib cage contracts. this is destroyed In this process, the shape of the side wall 210 on which the strap fastening part 200 is formed is deformed, and the strain sensor 120 may detect the respiration of the subject based on the displacement amount of the side wall 210 .

Therefore, even if the wearable sensing device 10 does not include the auscultation device and the breathing sensing device, respectively, the subject can simultaneously sense the body sound and respiration of the subject just by wearing the wearable sensing device 10 for animal diagnosis. there is an advantage

Meanwhile, as shown in FIG. 5 , a through hole 202 may be formed in the strap fastening portion 200 . The through-hole 202 is formed to have a specific diameter at a position adjacent to the partition wall portion 111 of the second thickness of the sidewall. The through hole 202 may displace the rigidity of the strap fastening part 200 according to the size of the diameter, and thus the elastic force of the strap fastening part 200 may be adjusted. A plurality of through-holes 202 may be formed in one strap fastening part 200 .

On the other hand, as shown in FIG. 7 , the strap fastening part 200 is not formed in a ring shape, and both ends may be connected to the sidewall of the main body housing 100 . In this case, the side wall of the body housing 100 to which the strain sensor 120 is attached may be formed to have a relatively thinner thickness than when the strap fastening part 200 is formed in a ring shape. In addition, even when both ends of the strap fastening portion 200 are connected to the sidewall of the main body housing 100 , the sidewall of the main body housing 100 has a partition wall portion 112 having a first thickness and a partition wall portion 111 having a second thickness. ) may be included.

On the other hand, as shown in FIG. 12 , the strap fastening part 200 has a ring shape (ie, a shape in which one end is open 220) only on one of the side walls facing the body housing 100 ). is formed, and both ends of the other sidewall may be formed to be connected to the sidewall of the body housing 100 .

The partition wall part 112 of the first thickness and the partition wall part 111 of the second thickness may not be formed on the sidewall of the body housing 100 to which both ends of the strap fastening part 200 are connected. In addition, the piezoelectric sensor 120 may not be attached to the side wall of the body housing 100 to which both ends of the strap fastening part 200 are connected.

<Second embodiment>

The second embodiment relates to a device that is worn on the body of the subject and distinguishes the heart sound and lung sound of the subject using biological sounds and respiration sensed from the subject, and determines an abnormal state of the subject using the same. will be.

Hereinafter, a wearable diagnostic apparatus 300 for animals according to a second embodiment of the present invention will be described in detail with reference to the drawings.

8 is a perspective view illustrating an animal wearable diagnosis apparatus 300 according to a second embodiment of the present invention.

The auscultation sensor 130, the strain sensor 120, and the body housing 100 of the wearable diagnostic device 300 for animals described below are the auscultation sensors ( 130), the strain sensor 120, and the same configuration and effect as the body housing 100, and thus redundant description will be omitted.

The wearable diagnosis apparatus 300 for animals described in the second embodiment further includes a diagnosis module 340 in the wearable sensing apparatus 10 for diagnosing animals described in the first embodiment.

The diagnosis module 340 is mounted inside the wearable diagnosis apparatus 300 for animals. The diagnosis module 340 determines an abnormal state of the subject based on the first sensing signal of the strain sensor 120 and the second sensing signal of the auscultation sensor 130 .

The first sensing signal is detected through the strain sensor 120 which detects the contraction and relaxation of the lungs, that is, the respiration of the subject, and the second sensing signal is detected through the auscultation sensor 130 which detects a biological sound do.

The diagnosis module 340 determines whether an abnormal state has occurred in the lung of the subject and/or a specific type of lung disease in consideration of the first sensing signal and the second sensing signal together. Here, the diagnosis module 340 considers the first sensing signal and the second sensing signal together means a specified section (inhalation and exhalation, lung contraction and relaxation) of the first sensing signal detected by the strain sensor 120 . The second sensing signal corresponding to is determined as a lung sound, and the rest of the specified section (a section in which relaxation and contraction of the lungs are temporarily stopped) is determined as a heart sound, and the abnormal state of the subject is determined by considering them together.

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 the accumulation of fluid in the lungs, it is very important to detect the prognostic symptoms in advance, since when the lungs are filled with more than a predetermined standard, a serious situation that can no longer be reversed occurs.

Therefore, when the respiration cycle (respiration rate) of the present invention is calculated to exceed 20% of the normal state, the diagnostic module 340 of the present invention regards it as a prognostic stage of a serious state that is difficult to reverse and determines it as an 'abnormal state' or severe 'pulmonary edema' can be judged as here. Pre-stored information about the subject (respiration cycle or respiration rate in a normal state) may be used as a target for comparative judgment with respect to the respiration cycle (respiration rate).

That is, when the subject is a companion animal, data constructed on a normal respiratory cycle can be used according to the species, sex/male, age and weight of the companion animal, and when the subject is a human (human body), male/female Construction data for a normal respiratory cycle according to , age and weight, etc. may be used.

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

In another embodiment of the present invention, the diagnosis module 340 may determine a specific lung disease name by comparing the second sensing signal with various predefined lung disease waveforms.

9 is a graph showing waveforms of lung sounds according to various types of respiratory symptoms.

Referring to FIG. 9 attached, waveforms such as Tracheal Sound, Normal Lung Sound, Bronchial Breathing, Stridor, Wheeze, and Rhonchus are derived differently. do.

Accordingly, the diagnosis module 340 compares the similarity with the waveform for each respiratory symptom of FIG. 9 based on the second sensing signal, and when there is a waveform with a predetermined similarity or higher, the type of lung disease of the corresponding respiratory symptom can be specifically determined.

<Third embodiment>

The third embodiment is a system that is worn on a subject to sense a biological sound and respiration sensed from the subject, and receives the sensing information to classify the subject's heart sound and lung sound to determine an abnormal state of the subject is about

The biodiagnostic system for animals to be described below uses the wearable sensing device 10 for animal diagnosis described in the first embodiment to detect the body sound and respiration of a subject, and receives the sensing information from the diagnosis server 500 . An abnormal state of the subject is determined. Since the wearable sensing device 400 for diagnosing animals according to the third embodiment has the same configuration and effects as the wearable sensing device 10 for diagnosing animals described through the first embodiment, a redundant description will be omitted.

Hereinafter, a biodiagnostic system for animals according to a third embodiment of the present invention will be described in detail with reference to the drawings.

10 is a schematic diagram illustrating a biodiagnostic system for animals according to a third embodiment of the present invention, and FIG. 11 is a block diagram illustrating a biodiagnostic system for animals according to a third embodiment of the present invention.

10 , the wearable sensing device 400 for diagnosing an animal is worn on a subject (eg, chest) to sense respiration and biological sounds from the subject. The wearable sensing device 400 for diagnosing an animal senses the respiration of the subject using the strain sensor 430 , and senses the body sound of the subject using the auscultation sensor 420 . The wearable sensing device 400 for animal diagnosis transmits the first sensing signal for the detected respiration and the second sensing signal for the biological sound to the diagnosis server 500 through the wireless communication module 440 .

If communication from the wireless communication module 440 to the diagnosis server 500 is impossible due to the communication distance between the wireless communication module 440 and the diagnosis server 500, the wireless communication module 440 is a smart phone serving as a relay. (D) Alternatively, the first sensing signal and the second sensing signal may be transmitted to the diagnosis server 500 through the diagnosis terminal.

The wireless communication module 440 and the smart phone (D) or the diagnosis terminal transmit and receive signals through short-range wireless communication such as BLU (Bluetooth), Wifi, Zigbee, etc., and the smart phone (D) or the diagnosis terminal is the diagnosis server 500 and broadband wireless communication (LoRa or mobile communication network) can transmit and receive signals.

The diagnosis server 500 receives the first sensing signal and the second sensing signal from the wearable sensing device 400 for animals. The diagnosis server 500 determines an abnormal state of the subject based on the first sensing signal of the strain sensor 120 and the second sensing signal of the auscultation sensor 130 . For example, the diagnosis server 500 determines whether an abnormal state has occurred in the lung of the subject and/or a specific type of lung disease by considering the first sensing signal and the second sensing signal together.

Here, the diagnosis server 500 diagnoses on the basis of the first sensing signal and the second sensing signal of the auscultation sensor 130 is a specified section of the first sensing signal detected by the strain sensor 120 (inhalation and exhalation, It means that the second sensing signal corresponding to the contraction and relaxation of the lungs is determined as a lung sound, and the remaining sections of the specified section (the section in which the relaxation and contraction of the lungs are temporarily stopped) are determined as a heart sound.

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 the accumulation of fluid in the lungs, it is very important to detect the prognostic symptoms in advance, since when the lungs are filled with more than a predetermined standard, a serious situation that can no longer be reversed occurs.

Therefore, when the diagnosis server 500 of the present invention is calculated that the respiratory cycle (respiration rate) exceeds 20% of the normal state, it is regarded as a prognostic stage of a serious state that is difficult to return and is judged as an 'abnormal state' or severe 'pulmonary edema' can be judged as here. Pre-stored information about the subject (respiration cycle or respiration rate in a normal state) may be used as a target for comparative judgment with respect to the respiration cycle (respiration rate).

That is, when the subject is a companion animal, data constructed on a normal respiratory cycle can be used according to the species, sex/male, age and weight of the companion animal, and when the subject is a human (human body), male/female Construction data for a normal respiratory cycle according to , age and weight, etc. may be used.

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

In another embodiment of the present invention, the diagnosis server 500 may determine a specific lung disease name by comparing the second sensing signal with various predefined lung disease waveforms.

9 is a graph showing waveforms of lung sounds according to various types of respiratory symptoms.

Referring to FIG. 9 attached, waveforms such as Tracheal Sound, Normal Lung Sound, Bronchial Breathing, Stridor, Wheeze, and Rhonchus are derived differently. do.

Accordingly, the diagnosis server 500 compares the similarity with the waveform for each respiratory symptom of FIG. 9 based on the second sensing signal, and when there is a waveform with a predetermined similarity or higher, the type of lung disease of the corresponding respiratory symptom can be specifically determined. In the present embodiment, the diagnosis server 500 may determine an abnormal state of the heart and/or a specific type of cardiovascular disease.
