[0036] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0037] Example

[0038] The front sensor unit mentioned in this embodiment can be understood as an antenna unit or a radio frequency signal transmission module.

[0039] In addition, in this embodiment, the directions such as front, back, front side, back side, etc. can be understood as defining the facial direction of the human body. For example, the direction of the human face is front or front side, and the opposite direction is back or back side.

[0040] like Figures 1-8 As shown, in the first aspect, an embodiment of the present application provides a front sensor fixing mechanism for non-invasive lung water detection, including: a front wearing piece 204 wearable on the front side of the human body, a positioning component 203 fixed on the front wearing piece 204, an adjustment component 201 for connecting the front sensor unit 100 and located in front of the positioning component 203, and a limiting component 202 for limiting the adjustment circuit.

[0041] Exemplarily, the adjustment component 201 is located on the front side of the positioning component 203, the front sensing unit is located on the rear side of the positioning component 203, and the limiting component 202 is arranged between the adjustment component 201 and the front sensor unit 100, wherein the positioning component 203 can be fixed to the front wearing component 204 by suturing, and the limiting component 202 can be used to adapt to the adjustment component 201, and then after the adjustment of the adjustment component 201 is completed, the limiting component 202 and the adjustment component 201 are clamped, etc.

[0042] The front wearing component 204 includes a front wearing fabric and an adjustment belt (not shown in the figure). The adjustment belt is connected to the front wearing fabric to fix the front wearing fabric to the human body. The front wearing fabric can be sewn from a textile part and an elastic part. The textile part is also called textile fiber, which is generally divided into two categories: natural fiber and chemical fiber. Natural fiber refers to textile fiber that exists in nature or is directly obtained from artificially cultivated animals; chemical fiber is textile fiber made of natural or synthetic polymers by a certain method; and the elastic part is filled in the interior of the fabric to achieve good comfort and breathability, wherein the elastic part includes but is not limited to sponges.

[0043] The front sensor unit 100 includes a sensing housing 101, an antenna assembly and an absorbing assembly 102 located within the sensing housing 101, a positioning member 103 provided on the sensing housing 101 for determining the positional relationship between the front sensor unit 100 and a specific part of the human body, the antenna assembly for receiving radio frequency signals, the absorbing assembly 102 being located at least on the front side of the antenna assembly, and the reception of radio frequency signals by the antenna assembly is not blocked by the absorbing assembly 102.

[0044] In some embodiments, the absorbing component 102 is made of absorbing material. By arranging the absorbing component 102 on the front side of the antenna component, the radio frequency signal can be prevented from being emitted from the front side of the front sensor unit 100. At the same time, the front side of the front sensor unit 100 can be shielded from external signal interference, thereby improving the accuracy of detection.

[0045] As one application example, the positioning member 103 extends from the sensor housing 101 toward the human neck. For example, the angle between the positioning member 103 and the sensor housing 101 is between 30° and 60°. Thus, the current position of the front sensor unit 100 can be determined and adjusted by illustrating the relative positional relationship between the positioning member 103 and a specific location on the human neck. This positional representation makes determining and adjusting the position of the front sensor unit 100 more intuitive.

[0046] In the above implementation process, a positioning component 203 is provided on the front wearable component 204, and the adjustment component 201 is connected to the front sensor unit 100. The user can adjust the position of the sensor unit through the adjustment component 201 according to the body shape of different people under the limited adjustment circuit of the positioning component 203 and the limit component 202 to achieve an accurate positioning position, and make the front sensor unit 100 fit the front side of the human body, so as to facilitate the front sensor unit 100 to perform lung water detection on the human body.

[0047] like Figure 2 As shown, the rear side of the front wearing component 204 is provided with a recess for placing the front sensor unit 100, and the size of the recess is not less than the size of the front sensor unit 100, that is, when the front sensor unit 100 is placed in the recess, the front sensor unit 100 does not protrude from the recess, so that in actual use, the protrusion of the front sensor unit 100 can be avoided, and the discomfort caused by contacting the human body for lung water detection can be avoided.

[0048] In some embodiments, a wiring groove connected to the recess is provided on the rear side of the front wearable component 204, wherein the wiring groove can be used for the RF cable assembly 400 to pass through the wiring groove and then be connected to the front sensor unit 100, and when the RF cable assembly 400 is located in the wiring groove, the wiring groove can completely accommodate the RF cable assembly 400, preventing the RF cable assembly 400 from protruding from the wiring groove, thereby ensuring the comfort of the front sensor unit 100 after it fits the front side of the human body, wherein the RF cable is used to transmit RF signals.

[0049] like Figure 2-Figure 8 As shown, the adjustment component 201 includes an adjustment shell 2011, an adjustment connector positioned in the adjustment shell 2011, and an adjustment slide. The adjustment connector includes a connecting shaft 2013 protruding backward from the adjustment shell 2011 for connecting to the front sensor unit 100; the connecting end of the adjustment slide is exposed from the adjustment shell 2011, and is used to clamp and position the adjustment position after moving to the limit component 202.

[0050] Exemplarily, the adjustment connector is detachably connected to the inside of the adjustment shell 2011, and the connection method between the adjustment connector and the adjustment shell 2011 includes but is not limited to screw connection. After the adjustment connector is connected and fixed to the adjustment shell 2011, it can be used to fix the adjustment slider, wherein the connection end of the adjustment slider protrudes backward from the adjustment shell 2011 to be clamped and positioned with the limit component 202. The connection is stable and reliable, which facilitates the user to adjust the position of the adjustment component 201 and the front sensor unit 100, thereby improving the position adjustment efficiency.

[0051] like Figure 5 As shown, the adjustment sliding member includes two adjustment sliders 2014 and two elastic abutment members 2015. The two adjustment sliders 2014 are distributed along the left and right directions. The adjustment slider 2014 is provided with an avoidance opening. One end of each elastic abutment member 2015 extends from the avoidance opening to the interior of the adjustment slider 2014 and abuts against it. The other end of the elastic abutment member 2015 abuts against the adjustment shell 2011 to clamp and position the adjustment slider 2014 in the adjustment shell 2011.

[0052] Exemplarily, each of the adjusting sliders 2014 corresponds to an elastic abutment 2015, and the elastic abutment 2015 includes but is not limited to a reset spring. The two adjusting sliders 2014 are formed with the avoidance opening on the side away from each other. For example, the avoidance opening of one of the adjusting sliders 2014 is set on the left, and the avoidance opening of the other adjusting slider 2014 is set on the right. A connecting column may be set inside the adjusting slider 2014, and one end of the elastic abutment 2015 is sleeved on the connecting column, and the other end thereof abuts against the adjusting shell 2011, which can ensure the tightness of the adjusting slider 2014 connected to the adjusting shell 2011, and avoid the phenomenon that the adjusting slider 2014 and the limiting component 202 are not firmly clamped.

[0053] Of course, in other embodiments, the distribution direction of the elastic abutment 2015 can also be distributed along the up and down directions, that is, the avoidance opening of one of the adjusting sliders 2014 is set at the upper end, and the avoidance opening of the other adjusting slider 2014 is set at the lower end, and the elastic abutment 2015 extends from the avoidance opening to the interior of the adjusting slider 2014 and abuts against it; it can be understood that as long as the elastic abutment 2015 can abut against the adjusting slider 2014 and under the cover of the adjusting connector, it can be ensured that the adjusting slider 2014 and the limiting assembly 202 are firmly clamped.

[0054] In some embodiments, the adjustment connecting member includes an adjustment connecting plate 2012, the adjustment shell 2011 includes a first split located at the front side and a second split located at the rear side of the first split, the first split and the second split can be fixed by screws, and a receiving space is formed between the two splits, and the second split is provided with a frame for installing the adjustment slider 2014, and the frame is located in the receiving space, and the frame extends along the direction of the second split close to the first split to form two independent cavities 2016 distributed along the left and right directions, each of the cavities 2016 is provided with the adjustment slider 2014 and the elastic abutment 2015, and the front side of each of the cavities 2016 is provided with an opening, the adjustment connecting plate 2012 covers the opening, so that the adjustment slider 2014 is fixed to the cavity 2016 under the action of the elastic abutment 2015 and the adjustment connecting plate 2012, ensuring that the adjustment slider 2014 and the limit assembly 202 are firmly clamped.

[0055] like Figure 2-Figure 4 As shown, the limiting component 202 includes a first limiting slide 2021 located on the front side of the positioning component 203 and a second limiting slide 2022 located on the rear side of the positioning component 203, the first limiting slide 2021 is connected to the second limiting slide 2022, for example, the first limiting slide 2021 and the second limiting slide 2022 are connected by screws, and the side of the first limiting slide 2021 facing away from the second limiting slide 2022 is connected to the adjusting component 201, wherein the limiting component 202 is provided with a moving circuit for synchronously moving the adjusting component 201 and the front sensor unit 100 in the up and down directions.

[0056] like Figure 3 As shown, the first limiting slide plate 2021 is provided with a limiting portion 2023 and a first avoidance groove 2024 . The limiting portion 2023 is distributed in the up and down directions, and the limiting portion 2023 is used to adapt to the adjustment component 201 . The connecting shaft 2013 passes through the first avoidance groove 2024 .

[0057] Please refer to Figure 3 and Figure 4 The limiting portion 2023 is configured to be tooth-shaped, and the adjusting slider 2014 is provided with a convex portion 2017. One side of the convex portion 2017 is configured to be tooth-shaped. The convex portion 2017 extends to the inner cavity 2027 of the limiting portion 2023 and is adapted to the limiting portion 2023, which can ensure that the adjusting slider 2014 is more reliably connected to the limiting portion 2023 through the tooth-shaped structure on the convex portion 2017, thereby preventing the adjusting component 201 and the front sensor unit 100 from sliding off the limiting component 202 after adjustment.

[0058] Taking the limiting portion 2023 as an example, when the user needs to adjust the upper and lower positions of the front sensor unit 100, firstly, an upward or downward force is applied to the adjusting component 201. At this time, the tooth structure of the protrusion 2017 of the adjusting component 201 (that is, the position where the protrusion 2017 is set to be tooth-shaped) is squeezed by the limiting portion 2023 and gradually shrinks. The elastic abutment 2015 is separated from the tooth groove of the limiting portion 2023 at this position and enters the adjacent tooth groove, and this reciprocating movement is carried out until the adjusting component 201 is moved along the distribution direction of the first avoidance groove 2024. 01 and the front sensor unit 100 are adjusted to the corresponding height positions together, the elastic abutment 2015 returns to its original state, and the tooth groove of the protrusion 2017 (that is, the protrusion 2017 is set to a tooth-shaped position) is clamped with the tooth groove of the limiting portion 2023 to prevent the adjusting component 201 and the front sensor unit 100 from sliding off the limiting component 202. During the adjustment process of the adjusting component 201 and the front sensor unit 100, the relative positions of the limiting component 202 and the positioning component 203 are fixed, and the adjustment method is simple and reliable.

[0059] When the elastic abutting member 2015 abuts against the adjusting slider 2014 and the adjusting housing 2011 respectively, the elastic abutting member 2015 is in a compressed state.

[0060] like Figure 7-Figure 8 As shown, in order to achieve better limiting of the adjustment component 201 by the limiting component 202, a protrusion 2018 is provided on the side of the adjustment shell 2011 of the adjustment component 201 close to the limiting component. Accordingly, the first limiting slide 2021 of the limiting component 202 is provided with a matching groove 2028 adapted to the protrusion. The matching groove 2028 includes but is not limited to being distributed in the up and down directions, which can ensure that during the adjustment process, the adjustment component 201 will not be offset along the left and right directions relative to the limiting component 202.

[0061] Please refer to Figure 3 The second limiting slide 2022 is provided with a second avoidance groove 2025, and the second avoidance groove 2025 is used for avoidance when the adjustment component 201 is connected to the front sensor unit 100.

[0062] In some embodiments, the positioning assembly 203 includes a first positioning plate 2031 and a second positioning plate 2032 , wherein the first positioning plate 2031 is connected to the second positioning plate 2032 , and both the first positioning plate 2031 and the second positioning plate 2032 are located between the first limiting slide 2021 and the second limiting slide 2022 ;

[0063] The first positioning plate 2031 is provided with a sliding groove 2033 on one side close to the second limiting slide 2022, and the sliding groove 2033 is arranged to be distributed along the left and right directions. The second limiting slide 2022 is provided with a protrusion 2026, and the protrusion 2026 is arranged in the sliding groove 2033, wherein the left and right directions are perpendicular to the up and down directions.

[0064] Exemplarily, the first positioning plate 2031 can be fixed to the front wearing component 204 by sewing, and the second positioning plate 2032 can be fixed to the first positioning plate 2031 by sewing. The second positioning plate 2032 includes but is not limited to a frame shape, which can be used to reveal the sliding groove 2033 distributed along the left and right directions on the first positioning plate 2031.

[0065] It can be understood that in the actual left and right position adjustment, the adjustment component 201, the front sensor unit 100 and the limit component 202 can be treated as a whole. It is only necessary to move the protrusion 2026 of the limit component 202 relative to the sliding groove 2033 to complete the position adjustment. That is to say, in the process of left and right position adjustment, the positions of the adjustment component 201, the front sensor unit 100 and the limit component 202 are relatively fixed.

[0066] In the above process, by adapting the protrusion 2026 and the sliding groove 2033, the left and right position adjustment of the adjustment component 201, the front sensor unit 100 and the limit component 202 relative to the positioning component 203 can be completed. At the same time, the up and down position adjustment of the adjustment component 201 and the front sensor unit 100 relative to the limit component 202 can ensure that the front sensor unit 100 moves to the corresponding position of the human body for detection, thereby adapting to different people.

[0067] like Figure 9 As shown, in a second aspect, the present application also provides a portable lung water detector, comprising: the front sensor fixing mechanism and the front sensor unit 100 for non-invasive lung water detection as described above.

[0068] In one application example, the spirometer further includes a rear sensor fixing mechanism and a radio frequency cable assembly 400. The front sensor fixing mechanism is located on the front side (chest) of the human body and is used to fix the front sensor unit 100. The front sensor unit 100 is used to receive radio frequency signals transmitted by the rear sensor unit located on the back side (back) of the human body. The radio frequency cable assembly 400 connects the front sensor unit 100 and the rear sensor unit, respectively, to form an exchange of radio frequency signals. The front sensor unit 100 and the rear sensor unit are controlled by a main unit 500. For example, when measuring spirometer water content, the two sensor units are worn on the back and front sides of the human body, corresponding to the locations of the lung lobes. By transmitting radio frequency signals to the lung lobes and then receiving the radio frequency signals that have passed through the lung lobes, one or more biological parameters are calculated and / or measured based on the dielectric properties of the organ or tissue, thereby achieving the current measurement of spirometer water content. The use of radio frequency or microwave radiation for monitoring and diagnosing body tissues has many application examples in the prior art and will not be elaborated here.

[0069] Compared with the traditional measurement method, the present embodiment does not require the patient to inhale and exhale additional auxiliary gas during the entire measurement process. The measurement process is simpler and more efficient, and no disposable consumables are generated, and the application cost is also lower.

[0070] In all embodiments of the present application, "big" and "small" are relative, "more" and "less" are relative, and "up" and "down" are relative. The expressions of such relative terms will not be elaborated in the embodiments of the present application.
