Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a portable host device and a lung effusion monitoring system for lung effusion monitoring. Background Technology

[0002] Heart failure is a common cardiovascular disease. In the clinical management of heart failure and other diseases, monitoring lung water content is a feasible and rapid way to assess the progression of heart failure patients. Traditional monitoring methods, such as chest CT, have problems such as insufficient sensitivity, radiation exposure, and inability to dynamically and continuously measure lung water in the early stages. Against this background, non-invasive lung water measurement technology has emerged. This technology emits low-frequency electromagnetic signals into the lungs and measures the dielectric properties of lung tissue. The lung water content is calculated using the wave impedance method. However, existing non-invasive lung water monitoring is mainly carried out in hospitals and requires the participation of medical staff. For patients who need to monitor at home for a long time, each visit to the hospital for monitoring is costly and inconvenient. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a portable main unit device for lung water monitoring that can facilitate daily home monitoring of lung water indicators.

[0004] To solve the above-mentioned technical problems, this application adopts the following technical solution: In a first aspect, this application provides a portable host device for monitoring pulmonary edema, including a host base for fixed connection with a wearable garment and a host detachably mounted on the host base; the host base includes a base plate that can be fixed to the wearable garment, a mounting member that can be fixed to the base plate, and a host connector located between the base plate and the mounting member; the host connector includes a hidden portion hidden inside the wearable garment and a snap-fit ​​receiving portion that extends forward through the mounting member for snapping the host; the host includes a snap-fit ​​receiving portion that snaps into the snap-fit ​​receiving portion and a handheld portion located outside the snap-fit ​​receiving portion.

[0005] In the implementation of the above technical solution, the mounting component acts as a connector, enabling the connection between the main unit connector and the wearable garment. The main unit connector has a hidden part and a snap-fit ​​receiving part, so that the main unit connector is not completely exposed, but part of it is hidden inside the wearable garment, while the snap-fit ​​receiving part is exposed outside the wearable garment, thus facilitating snap-fit ​​with the snap-fit ​​receiving part of the main unit. At the same time, the hidden part also increases the contact area with the mounting component, improving the installation stability of the main unit connector. The handheld part of the main unit is located outside the snap-fit ​​receiving part, making it convenient for the patient to snap the main unit onto the main unit base and also convenient to remove the main unit from the main unit base. Since the main unit base is fixed to the wearable garment, after the patient puts on the wearable garment, the main unit can be directly snapped onto the snap-fit ​​receiving part on the main unit base to realize the monitoring of pulmonary edema indicators. There is no need for monitoring in the hospital, nor is it necessary for medical staff to participate or provide guidance. It can be completed at home, which is convenient to operate. Moreover, the main unit is small in size. During the monitoring process, the main unit is directly inserted into the main unit base of the wearable garment. There is no need to carry the main unit by hand, making it convenient to carry and meeting the needs of daily home monitoring.

[0006] In one embodiment, the snap-fit ​​receiving part has a receiving groove, and the main unit includes a first housing, which is snapped into the receiving groove. The receiving groove extends through the front end and the top end of the snap-fit ​​receiving part and forms a latch at the top end. The latch is used for the first housing to snap into or out of the receiving groove.

[0007] In the implementation of the above technical solution, the receiving groove runs through the front end and top end of the snap-fit ​​receiving part, and a snap-fit ​​opening is formed at the top end, so as to facilitate the first housing to snap into or out of the receiving groove.

[0008] In one embodiment, a slot is provided on the side plate of the snap-fit ​​receiving part; the snap-fit ​​part includes a positioning part, which is pressably disposed on the side of the first housing. The positioning part has a pressed state and a non-pressed state. In the non-pressed state, the positioning part can engage with the slot to prevent the first housing from exiting the receiving groove from the snap-fit ​​opening. In the pressed state, the positioning part can disengage from the slot to allow the first housing to exit the receiving groove from the snap-fit ​​opening.

[0009] In the implementation of the above technical solution, a slot is provided on the side plate of the snap-fit ​​receiving part, and the positioning part can be snapped into the slot, thereby realizing the snap-fit ​​between the first housing and the snap-fit ​​receiving part. At the same time, the positioning part can contact the slot in the pressing state, so that the first housing can be detached from the receiving groove. The positioning part has two states, which is convenient to operate and easy to implement.

[0010] In one embodiment, the host includes a push button connected to the positioning part, the push button being located above the positioning part, the push button being able to switch the state of the positioning part, and the push button being located outside the receiving groove.

[0011] In the implementation of the above technical solution, the state of the positioning part can be switched by pressing the push part. The push part is located above the positioning part. When the main unit is located outside the receiving groove, it is convenient to press the push part when it is necessary to separate the main unit from the main unit base. The receiving groove will not interfere with the push part, thereby facilitating the disassembly of the main unit and achieving the purpose of quick disassembly.

[0012] In one embodiment, the first housing includes two first sidewalls on opposite sides along a first direction. The first sidewalls include the hand-held portion, the recessed portion, and the stepped surface. The snap-fit ​​portion includes the recessed portion and the stepped surface. The hand-held portion and the recessed portion are connected through the stepped surface. Along the first direction, the recessed portion is recessed from the outside to the inside. The positioning portion is disposed in the recessed portion, and the pressing portion is disposed in the hand-held portion.

[0013] In the implementation of the above technical solution, the first sidewall includes a hand-held part, a recessed part, and a stepped surface. Since the recessed part is recessed from the outside to the inside, the local width of the first housing is narrower. In this way, the recessed part and the stepped surface can be engaged in the receiving groove, forming a double engagement with the positioning part, thus improving stability. Furthermore, the hand-held part is located outside the receiving groove, which makes it convenient to hold the main unit and place or remove it from the receiving groove. In addition, the push part is located on the hand-held part, so when the push part is pressed, it will also control the positioning part on the recessed part, and the receiving groove will not interfere with the push part, making operation convenient.

[0014] In one embodiment, the snap-fit ​​receiving part includes a bottom wall and two side plates. The bottom wall connects the two side plates, and the bottom wall and the two side plates enclose the receiving groove. The snap-fit ​​opening is located on the side of the snap-fit ​​receiving part away from the bottom wall. The main unit includes a first connector installed in the first housing and a first circuit board disposed in the first housing. The first connector is electrically connected to the first circuit board. A second connector is disposed on the bottom wall. A second circuit board for analyzing lung water indicators is sandwiched between the main unit connector and the bottom plate. The second connector is electrically connected to the second circuit board, and the second connector is plugged into the first connector.

[0015] In the implementation of the above technical solution, by setting a second connector on the bottom wall of the snap-fit ​​receiving part, the main unit includes a first connector. When the main unit snaps into the snap-fit ​​receiving part, the first connector can be inserted into the second connector to achieve connection. At the same time, since the second circuit board for analyzing lung water indicators is set inside the main unit base, and the main unit base is installed on the wearable clothing, the size of the main unit can be reduced. That is, the circuit board for analyzing lung water indicators no longer needs to be set inside the main unit. Instead, the second circuit board is transferred to the main unit base, which meets the requirement of miniaturization of the main unit and eliminates the need to carry the main unit by hand.

[0016] In one embodiment, the host includes a battery module disposed within the first housing and electrically connected to the first circuit board.

[0017] In the implementation of the above technical solution, since a battery module is provided inside the first housing and is electrically connected to the first circuit board, when measurement is required, the main unit is snapped into the snap-fit ​​receiving part, and the first connector and the second connector are inserted into each other. At the same time, since the battery module is electrically connected to the first circuit board and the first circuit board is electrically connected to the first connector, the battery module can provide power to the second circuit board, thereby realizing the measurement of lung water indicators. The main unit can also be removed from the snap-fit ​​receiving part to realize the charging of the main unit separately, which is convenient to operate.

[0018] In one embodiment, the host includes a display module electrically connected to the first circuit board, and the display module is disposed on the side of the first housing opposite to the base plate.

[0019] In the implementation of the above technical solution, by setting up a display module, it is possible to display information such as the current power level of the host and the patient's pulmonary edema index, so that the patient can see the current pulmonary edema index more intuitively.

[0020] In one embodiment, a switch button and a measurement button are provided on the top of the first housing, and both the switch button and the measurement button are electrically connected to the first circuit board.

[0021] In the implementation of the above technical solution, the switch button can control the host to turn on and off, while the measurement button can perform measurements after the host is turned on.

[0022] In one embodiment, the host includes a fixed base and an elastic element. The fixed base is installed inside the first housing, and the elastic element is disposed between the positioning part and the fixed base. The elastic element is used to drive the positioning part to move so that the positioning part switches from the pressed state to the non-pressed state.

[0023] In the implementation of the above technical solution, by setting a fixed base and an elastic element, the positioning part can be switched from a pressed state to a non-pressed state, so that the positioning part can automatically spring back when the main unit is removed from the main unit base.

[0024] In one embodiment, the fixed base is provided with a guide groove along a first direction, the main unit includes a pressing part, the pressing part is connected to the positioning part, the pressing part has a protrusion, the protrusion is slidably engaged in the guide groove, and the first direction is parallel to the pressing direction of the pressing part.

[0025] In the implementation of the above technical solution, the fixed seat is provided with a guide groove, the pressing part has a protrusion, the protrusion can slide along the guide groove, the fixed seat supports the pressing part, so that the pressing part can slide back and forth in the first direction to realize the switching of the state of the positioning part.

[0026] In one embodiment, the mounting component is provided with a first window, and the snap-fit ​​receiving portion passes through the first window and protrudes from the surface of the mounting component opposite to the first housing.

[0027] In the implementation of the above technical solution, the mounting component is provided with a first window, which allows part of the host connector to be hidden inside the wearable garment, while the other part protrudes from the first window, providing space for the host to be snapped in, making it convenient for the host to be snapped in to the snap-in receiving part.

[0028] Secondly, this application provides a lung effusion monitoring system, including a front sensor, a rear sensor, the wearable garment, and the portable host device mentioned in the first aspect. The front sensor, the rear sensor, and the host device are all fixed to the wearable garment. The front sensor and the rear sensor are both electrically connected to the second circuit board. The rear sensor is used to emit electromagnetic waves to the human lungs, and the front sensor is used to receive the electromagnetic waves.

[0029] In the implementation of the above technical solution, the wearable clothing is equipped with a front sensor, a rear sensor, and a main unit. When the main unit and the main unit are connected, lung water monitoring can be completed. The lung water monitoring system meets the requirements for daily monitoring and does not require the participation of professional medical staff. It can monitor lung water content without being in a hospital or under the operation or guidance of professional medical staff. Attached Figure Description

Detailed Implementation

[0033] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0034] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] Current non-invasive pulmonary edema monitoring is mainly conducted in hospitals and requires the participation of medical staff. For patients who need long-term home monitoring, each trip to the hospital is costly and inconvenient.

[0036] Therefore, in the first aspect, such as Figures 1 to 4 As shown, this application provides a portable host device for monitoring pulmonary edema, including a host base 1 for fixed connection with a wearable garment 4 and a host 2 detachably mounted on the host base 1. The host base 1 includes a base plate 11 that can be fixed to the wearable garment 4, a mounting member 14 that can be fixed to the base plate 11, and a host connector 13 located between the base plate 11 and the mounting member 14; the host connector 13 includes a hidden portion 131 hidden inside the wearable garment 4 and a snap-fit ​​receiving portion 12 that passes forward through the mounting member 14 for snapping the host 2. The host 2 includes a snap-fit ​​portion that snaps into the snap-fit ​​receiving portion 12 and a handheld portion 2111 located outside the snap-fit ​​receiving portion 12.

[0037] Optionally, the mounting component 14 has a connecting surface on the side facing the wearable garment 4, and the connecting surface is connected to the wearable garment 4 by adhesive.

[0038] The base plate 11 and the main unit connector 13 are fastened together to form a second housing, which is used to accommodate the second circuit board.

[0039] Mounting component 14 can be connected to base plate 11, thereby realizing the connection between base plate 11, main unit connector 13 and mounting component 14.

[0040] In this embodiment, the mounting component 14 serves as a connector, enabling the connection between the main unit connector 13 and the wearable garment 4. The main unit connector 13 has a hidden portion 131 and a snap-fit ​​receiving portion 12, so that the main unit connector 13 is not entirely exposed, but partially hidden inside the wearable garment 4. The snap-fit ​​receiving portion 12 is exposed outside the wearable garment 4, thus facilitating snap-fit ​​with the snap-fit ​​portion of the main unit 2. At the same time, the hidden portion 131 also increases the contact area with the mounting component 14, improving the installation stability of the main unit connector 13. The handheld portion 2111 of the main unit 2 is located outside the snap-fit ​​receiving portion 12, thus facilitating... The patient can easily attach the main unit 2 to the main unit base 1 and also easily remove the main unit 2 from the main unit base 1. Since the main unit base 1 is fixed to the wearable garment 4, after the patient puts on the wearable garment 4, the main unit 2 can be directly attached to the attachment part 12 on the main unit base 1 to monitor pulmonary edema. This can be done at home without the need for monitoring in a hospital or the involvement and guidance of medical staff. It is easy to operate. In addition, the main unit 2 is small in size. During the monitoring process, the main unit 2 is directly inserted into the main unit base 1 of the wearable garment 4. There is no need to carry the main unit 2 by hand, making it easy to carry and meeting the needs of daily home monitoring.

[0041] like Figure 1 As shown, in one embodiment, the snap-fit ​​receiving part 12 has a receiving groove 121. The main unit 2 includes a first housing 21, which is snapped into the receiving groove 121. The receiving groove 121 passes through the front end and the top end of the snap-fit ​​receiving part 12 and forms a latch at the top end. The latch is used for the first housing 21 to snap into or out of the receiving groove 121.

[0042] The first housing 21 is used to accommodate some components of the main unit 2. The first housing 21 is formed by two parts being fastened together, which facilitates the installation of some components inside the first housing 21.

[0043] In this embodiment, the receiving groove 121 extends through the front end and the top end of the snap-fit ​​receiving part 12, and forms a snap at the top end, thereby facilitating the first housing 21 to snap into or out of the receiving groove 121.

[0044] like Figure 1 and 4 As shown, in one embodiment, the side plate 123 of the snap-fit ​​receiving part 12 is provided with a snap-fit ​​groove 1211; the snap-fit ​​part includes a positioning part 24, which is pressably disposed on the side of the first housing 21. The positioning part 24 has a pressed state and a non-pressed state. When the positioning part 24 is in the non-pressed state, it can snap-fit ​​with the snap-fit ​​groove 1211 to prevent the first housing 21 from exiting the receiving groove 121 from the snap-fit ​​opening. When the positioning part 24 is in the pressed state, it can disengage from the snap-fit ​​groove 1211 to allow the first housing 21 to exit the receiving groove 121 from the snap-fit ​​opening.

[0045] In this embodiment, a slot 1211 is provided on the side plate 123 of the snap-fit ​​receiving part 12, and the positioning part 24 can be snapped into the slot 1211, thereby realizing the snap-fit ​​between the first housing 21 and the snap-fit ​​receiving part 12. At the same time, the positioning part 24 can contact the slot 1211 in the pressing state, so that the first housing 21 can be disengaged from the receiving groove 121. The positioning part 24 has two states, which is convenient to operate, easy to implement, and does not require the participation and guidance of medical personnel.

[0046] like Figure 4 and 5 As shown, in one embodiment, the host 2 includes a push part 29, which is connected to the positioning part 24. The push part 29 is located above the positioning part 24 and can switch the state of the positioning part 24. The push part 29 is located outside the receiving groove 121.

[0047] Optionally, the push part 29 and the snap-fit ​​part are an integral piece.

[0048] In this embodiment, the state of the positioning part 24 can be switched by pressing the pressing part 29. The pressing part 29 is located above the positioning part 24. When the main unit 2 is located outside the receiving groove 121, it is convenient to press the pressing part 29 when it is necessary to separate the main unit 2 from the main unit base 1. The receiving groove 121 will not interfere with the pressing part 29, thereby facilitating the disassembly of the main unit 2 and achieving the purpose of quick disassembly.

[0049] like Figure 4 As shown, in one embodiment, the first housing 21 includes two first sidewalls 211 on opposite sides along the first direction X. The first sidewalls 211 include a handhold portion 2111, a recessed portion 2113, and a stepped surface 2112. The engaging portion includes the recessed portion 2113 and the stepped surface 2112. The handhold portion 2111 and the recessed portion 2113 are connected by the stepped surface 2112. Along the first direction X, the recessed portion 2113 is recessed from the outside to the inside. The positioning portion 24 is disposed in the recessed portion 2113, and the pressing portion 29 is disposed in the handhold portion 2111.

[0050] The first housing 21 is a square housing, which allows it to have two opposing first sidewalls 211 along the first direction X.

[0051] In this embodiment, the first sidewall 211 includes a handheld portion 2111, a recessed portion 2113, and a stepped surface 2112. Since the recessed portion 2113 is recessed from the outside to the inside, the local width of the first housing 21 is narrower. Thus, the recessed portion 2113 and the stepped surface 2112 can be engaged in the receiving groove 121, forming a double engagement with the positioning portion 24, thereby improving stability. Furthermore, the handheld portion 2111 is located outside the receiving groove 121, which makes it convenient to hold the main unit 2 and place or remove the main unit 2 from the receiving groove 121. In addition, the push part 29 is provided in the handheld portion 2111. Thus, when the push part 29 is pressed, it also controls the positioning portion 24 on the recessed portion 2113, and the receiving groove 121 will not interfere with the push part 29, making operation convenient.

[0052] In the previously announced lung effusion monitoring host, the monitoring host needs to have circuit boards for processing lung effusion indicators as well as other circuit boards for functions such as power control, Bluetooth, sound, and display. All of these circuit boards are integrated into the casing of the monitoring host, which results in the large size of the monitoring host and makes it inconvenient to carry.

[0053] like Figure 4 and 6 As shown, in one embodiment, the snap-fit ​​receiving part 12 includes a bottom wall 122 and two side plates 123. The bottom wall 122 connects to the two side plates 123, and the bottom wall 122 and the two side plates 123 enclose a receiving groove 121. The snap-fit ​​opening is located on the side of the snap-fit ​​receiving part 12 away from the bottom wall 122. The main unit 2 includes a first connector 27 installed on the first housing 21 and a first circuit board 22 disposed in the first housing 21. The first connector 27 is electrically connected to the first circuit board 22. A second connector 15 is disposed on the bottom wall 122. A second circuit board for analyzing lung water indicators is sandwiched between the main unit connector 13 and the bottom plate 11. The second connector 15 is electrically connected to the second circuit board, and the second connector 15 is inserted into the first connector 27.

[0054] The first connector 27 can be a Pog Pin socket, and the second connector 15 can be a Pog Pin connector. The first connector 27 and the second connector 15 are plugged into each other to achieve electrical connection.

[0055] The chip module on the first circuit board 22 can control functions such as power supply, Bluetooth, sound, and display. In the blood, lung parenchyma, and air within the lungs, water has a very high dielectric constant, while air has the lowest, a significant difference. This difference causes variations in the impedance values ​​of different lung components to electromagnetic waves. By measuring the dielectric properties of lung tissue, the second circuit board uses the impedance method to calculate the lung water content.

[0056] The higher the dielectric constant, the lower the wave impedance, and the more pronounced the propagation characteristics of electromagnetic waves in the medium.

[0057] In this embodiment, by providing a second connector 15 on the bottom wall 122 of the snap-fit ​​receiving part 12, the main unit 2 includes a first connector 27. When the main unit 2 snaps into the snap-fit ​​receiving part 12, the first connector 27 can be inserted into the second connector 15 to achieve connection. At the same time, since the second circuit board for analyzing lung water indicators is placed inside the main unit base 1, and the main unit base 1 is installed on the wearable clothing 4, the size of the main unit 2 can be reduced. That is, the circuit board for analyzing lung water indicators does not need to be set inside the main unit 2. Instead, the second circuit board is transferred to the main unit base 1, which meets the requirement of miniaturization of the main unit 2. It also eliminates the need to carry the main unit 2 by hand. After the main unit 2 is inserted into the main unit base 1, the power is connected, which can achieve the purpose of daily home monitoring of lung water indicators. Patients do not need to go to the hospital for lung water indicator monitoring, nor does it require the participation and guidance of medical staff. The operation is convenient.

[0058] Optionally, the second circuit board is equipped with a control module and a radio frequency module. The control module carries a core computing program that processes the raw data returned by the radio frequency module using algorithms and calculates the final analysis result of the percentage of lung water content using the wave impedance method. The radio frequency module is responsible for transmitting and receiving electromagnetic signals and collecting raw dielectric data of lung tissue, but does not participate in the result analysis and calculation.

[0059] like Figure 7 and 8 As shown, in one embodiment, the host 2 includes a battery module 28, which is disposed inside the first housing 21 and is electrically connected to the first circuit board 22.

[0060] The first housing 21 is provided with a charging port, which is electrically connected to the battery module 28. When the power cord is connected to the charging port.

[0061] In this embodiment, since a battery module 28 is provided inside the first housing 21 and the battery module 28 is electrically connected to the first circuit board 22, when measurement is required, the main unit 2 is snapped into the snap-fit ​​receiving part, and the first connector 27 and the second connector 15 are inserted into each other. At the same time, since the battery module 28 is electrically connected to the first circuit board 22 and the first circuit board 22 is electrically connected to the first connector 27, the battery module 28 can provide power to the second circuit board, thereby realizing the measurement of lung water index. The main unit 2 can also be removed from the snap-fit ​​receiving part 12 to realize the independent charging of the main unit 2. The operation is convenient and monitoring can be completed at home.

[0062] like Figure 7 and 8As shown, in one embodiment, the host 2 includes a display module 23, which is electrically connected to the first circuit board 22. The display module 23 is disposed on the side of the first housing 21 away from the bottom plate 11.

[0063] The display module 23 is connected to the first circuit board 22 via a flexible circuit board, providing an information interaction window, and is also fixedly connected to the first housing 21 via screws.

[0064] In this embodiment, by setting up a display module 23, the current power level of the host 2 and information such as the patient's lung water index can be displayed, so that the patient can see the current lung water index more intuitively.

[0065] like Figure 7 As shown, in one embodiment, the top of the first housing 21 is provided with a switch button 3 and a measurement button, both of which are electrically connected to the first circuit board 22.

[0066] Optionally, the switch button 3 and the measurement button can be connected to the first circuit board 22 via a flexible circuit board.

[0067] In this embodiment, the switch button 3 can control the host 2 to turn on and off, and the measurement button can perform measurements after the host 2 is turned on, thereby enabling home monitoring of lung effusion indicators without the need for medical personnel to participate or provide guidance, making it easy to operate.

[0068] like Figure 9 and 10 As shown, in one embodiment, the host 2 includes a fixed base 25 and an elastic member 26. The fixed base 25 is installed in the first housing 21, and the elastic member 26 is disposed between the positioning part 24 and the fixed base 25. The elastic member 26 is used to drive the positioning part 24 to move so that the positioning part 24 switches from a pressed state to a non-pressed state.

[0069] Optionally, along the second direction Y, one end of the fixing seat 25 is snapped into the first housing 21, and the other end can be fixedly connected to the first housing 21 by fasteners, with the second direction Y being perpendicular to the first direction X.

[0070] Optionally, the elastic element 26 is disposed between the push part 29 and the fixed base 25, so that when the push part 29 is pressed, force can be applied directly to the elastic element 26 and the rebound effect is better.

[0071] A positioning groove for accommodating the elastic element 26 is provided between the push part 29 and the fixed base 25 to prevent the elastic element 26 from coming out.

[0072] In this embodiment, by setting the fixed base 25 and the elastic element 26, the positioning part 24 can be switched from the pressed state to the non-pressed state, so that when the main unit 2 is removed from the main unit base 1, the positioning part 24 can automatically spring back.

[0073] like Figure 7 , 9 As shown in Figure 10, in one embodiment, the fixed base 25 is provided with a guide groove 2511 along the first direction X. The main unit 2 includes a pressing part 29, which is connected to the positioning part 24. The pressing part 29 has a protrusion 241, which is slidably engaged in the guide groove 2511. The first direction X is parallel to the pressing direction of the pressing part 29.

[0074] Optionally, two guide portions 291 are also provided on the side of the pressing part 29 facing the fixed base 25. The guide portions 291 are spaced apart along the second direction Y. The fixed base 25 includes a first piece 251, a second piece 252 and a fixed block 253. The first piece 251 is provided with a guide groove 2511. The first piece 251 and the second piece 252 are arranged perpendicular to each other. The second piece 252 is connected to the first housing 21. The two guide portions 291 are located on both sides of the fixed block 253. When the pressing part 29 is pressed, the two guide portions 291 can also slide synchronously and slide along the fixed block 253 to improve the stability of the pressing part 29.

[0075] In this embodiment, the fixed base 25 is provided with a guide groove 2511, and the pressing part 29 has a protrusion 241. The protrusion 241 can slide along the guide groove 2511. The fixed base 25 supports the pressing part 29, so that the pressing part 29 can slide back and forth in the first direction X to realize the switching of the state of the positioning part 24.

[0076] like Figure 6 As shown, in one embodiment, the mounting member 14 is provided with a first window 141, and the snap-fit ​​receiving part 12 passes through the first window 141 and protrudes from the surface of the mounting member 14 away from the first housing 21.

[0077] The wearable garment 4 is provided with a second window 41, which corresponds to the first window 141. The snap-fit ​​receiving part 12 passes through the second window 41 and the first window 141 in sequence. The reason why the wearable garment 4 is provided with a second window 41 is to increase the contact area with the mounting part 14 and improve the stability between the mounting part 14 and the wearable garment 4.

[0078] In this embodiment, the mounting component 14 is provided with a first window 141, which allows a part of the host connector 13 to be hidden inside the wearable garment 4, while the other part protrudes from the first window 141, providing space for the host 2 to be snapped in, so that the host 2 can be snapped in to the snap-in receiving part 12.

[0079] like Figure 1 and 4As shown, in a second aspect, embodiments of this application also provide a lung effusion monitoring system, including a front sensor 5, a rear sensor 6, a wearable garment 4, and a portable host device provided in the first aspect. The front sensor 5, the rear sensor 6, and the host base 1 are all fixed to the wearable garment 4. The front sensor 5 and the rear sensor 6 are both electrically connected to a second circuit board. The rear sensor 6 is used to emit electromagnetic waves to the human lungs, and the front sensor 5 is used to receive electromagnetic waves.

[0080] The front sensor 5 is connected to the second circuit board via the first radio frequency line, and the rear sensor 6 is connected to the second circuit board via the second radio frequency line.

[0081] The front sensor 5 and the rear sensor 6 can be adjusted in position on the wearable garment 4 using Velcro.

[0082] The radio frequency (RF) module on the second circuit board emits a series of RF signals. These signals are transmitted to the rear sensor 6 via the second RF line. The spiral antenna inside the rear sensor 6 changes the direction of the electromagnetic wave emission, causing it to propagate directionally in space. After passing through the lungs, the waves are received by the front sensor 5. The collected RF signals are then transmitted back to the RF module via the first RF line. The control module on the second circuit board performs a series of data processing steps to form a closed loop.

[0083] Optionally, the rear sensor 6 emits low-frequency electromagnetic waves. This utilizes the change in electrical impedance when low-frequency electromagnetic waves pass through chest tissue. As the water content of lung tissue increases, the electrical impedance decreases. The lower the frequency, the greater the penetration depth, enabling it to penetrate multiple layers of tissue such as skin, fat, muscle, and bone to reach the lungs.

[0084] Targeted propagation aims to focus on the measurement path and reduce interference from other organizations.

[0085] The rear sensor 6 transmits low-power, low-frequency electromagnetic signals into the human chest cavity via an internal helical antenna. The frequency range is typically between 0.7 and 2 GHz, the transmission power is ≤-20 dBm, and the pulse width is approximately 4 to 6 ms. The front sensor 5 receives the signal after it passes through the chest cavity and measures the following parameters: amplitude attenuation, phase change, and impedance value. The second circuit board uses the wave impedance method to inversely deduce the equivalent dielectric constant of the lung tissue based on the measured signal changes. The calculated equivalent dielectric constant of the lung is then converted into lung water content through a calibration model, such as the Debye-Maxwell model + Cole-Cole equation, to calculate the dielectric parameters of lung tissue under different water contents. Using multilayer transmission line theory, the interference from skin, fat, and muscle is peeled off layer by layer to extract the net lung signal.

[0086] Of course, the calculation process also involves corresponding interference sources, such as skin, fat, muscle, bone and heart. Skin can be compensated by removing interface reflections using average subtraction. Fat is compensated by estimating its thickness through phase delay using its low attenuation characteristics. Muscle, as a high attenuation layer, eliminates individual differences through baseline calibration. Bone is modeled as a transparent layer using its low conductivity and high penetration characteristics. The heart is compensated by using time-domain gating and adaptive noise cancellation.

[0087] Of course, other methods in the existing technology can also be used to analyze lung effusion indicators.

[0088] Optionally, after the patient puts on the wearable garment 4, the front sensor 5 is placed on the front side of the patient's right lung, and the rear sensor 6 is placed on the back side of the patient's right lung. That is, in this embodiment, the front sensor 5 and the rear sensor 6 are located on the front and back sides of the patient's right lung, respectively. This is because the left lung is close to the heart, and the tissue structures of the lung and the heart are quite different, which will interfere with the signal and affect the measurement results. Moreover, the beating of the heart itself will also affect the fit of the sensor.

[0089] The wearable suit 4 is equipped with a rear sensor mounting plate, which has multiple positions 7. The rear sensor 6 can be fixed to different positions 7. The multiple positions 7 are arranged in three rows horizontally and two rows vertically, forming a two-dimensional position matrix 7. The six positions 7 can cover people with different BMI values, improving the accuracy of monitoring. Taller patients can use the lowest position 7, medium-height patients can use the middle position 7, and shorter patients can use the highest position 7. The patient's BMI value can be calculated using existing software or programs.

[0090] Optionally, the rear sensor 6 and the gear position 7 can be connected by a snap-fit, which facilitates the connection and disassembly of the rear sensor 6 and the wearable garment 4 without the need for medical personnel to guide or participate, making it convenient for daily home monitoring. After the rear sensor 6 is fixed in position, it can be attached to the rear sensor fixing plate with Velcro for easy operation.

[0091] The front sensor 5 includes an indicator 51, which includes a ring. When worn, a finger passes through the ring and touches a marked position on the sternum to adjust the position of the front sensor 5, thereby improving the accuracy of monitoring.

[0092] In this embodiment, after the patient puts on the wearable garment 4 at home, based on the BMI value, the position of the rear sensor 6 is adjusted, and then the finger passes through the ring body to the sternum to mark the position, determining the position of the front sensor 5. The main unit 2 is then connected to the main unit base 1, and the switch button 3 and the measurement button on the main unit 2 are pressed. The battery module 28 in the main unit 2 supplies power to the second circuit board, and the monitoring of lung water indicators can begin. This lung water monitoring system meets the needs of daily home monitoring and does not require the participation of professional medical staff. It can monitor lung water content without being in a hospital or under the operation or guidance of professional medical staff. Meanwhile, the monitoring host 2 is small in size and does not need to be carried by hand, which meets the needs of daily home monitoring.
