[0003] Currently, there is no portable pulmonary edema detection device on the market, and there is no cable assembly for such a device. Therefore, there is an urgent need for a cable assembly to adapt to such a device. Summary of the Utility Model

[0043] Embodiment

[0044] In the sensor unit mentioned in the solution of this embodiment, it can be understood as an antenna unit or a radio frequency signal transmitting module.

[0045] In addition, in the solution of this embodiment, the directions such as front, back, or front side, back side, etc. can be understood as being defined according to the face direction of the human body. For example, the direction of the human face is the front or the front side, and the opposite direction is the back or the back side.

[0046] As Figures 1 - 7 shown, in a first aspect, an embodiment of the present application provides a radio frequency cable assembly for transmitting pulmonary edema detection signals, including at least two radio frequency cable groups 200, tube sleeves 100 respectively sleeved outside the two radio frequency cable groups 200, and two reinforcing members 300 respectively penetrating through the two tube sleeves 100 along the longitudinal direction. The radio frequency cable group 200 and the tube sleeve 100 can be relatively movable in the longitudinal direction, and both ends of each reinforcing member 300 extend out of the tube sleeve 100 to form a connection section.

[0047] Exemplarily, the radio frequency cable assembly can be applied to a pulmonary edema detector, where one end of each of the two radio frequency cable groups 200 is connected to a main component 500, one end of the other radio frequency cable group 200 is connected to a front sensor component, and the other end of the other radio frequency cable group 200 is connected to a rear sensor component, so as to realize the interaction of radio frequency signals.

[0048] It can be understood that the tube sleeve 100 includes but is not limited to a flexible tube, such as a rubber tube, etc., which can allow a certain deformation of the radio frequency cable group 200 during use. There are two tube sleeves 100, and the radio frequency cable group 200 and the reinforcing member 300 are respectively arranged inside each tube sleeve 100.

[0049] In the above implementation process, the tube sleeve 100 of each radio frequency cable group 200 and the radio frequency cable group 200 can be relatively movable in the longitudinal direction. Therefore, the pulling force borne after the installation of the radio frequency cable assembly mainly acts on the tube sleeve 100, and the radio frequency cable group 200 inside the tube sleeve 100 can be protected from the external pulling force. In addition, the durability of the portable pulmonary edema detector using this cable assembly is also improved. The present application is also provided with a reinforcing member 300 penetrating through the tube sleeve 100 along the longitudinal direction, which further improves the bearable pulling force.

[0050] As Figures 1 - 2 shown, the reinforcing member 300 includes a reinforcing wire 301 and a connecting wire 302. The reinforcing wire 301 is arranged inside the tube sleeve 100, and the connecting wire 302 connects the reinforcing wire 301 and extends to the outside of the tube sleeve.

[0051] Exemplarily, the reinforcing member 300 includes but is not limited to steel wires, that is, the materials of the reinforcing wires 301 and the connecting wires 302 can be set to be the same. The reinforcing wires 301 are located inside the tube sleeve 100 and are used to be in the same distribution direction as the RF wire group 200 inside the tube sleeve 100. After the connecting wires 302 are connected to the reinforcing wires 301, a certain angle is formed. This angle can be 0 - 90°, or 90 - 180°. And the formation of the connecting wires 302 and the reinforcing wires 301 can be achieved by bending the end of the reinforcing member 300, or directly fixing the connecting wires 302 to the reinforcing wires 301. The fixing methods include but are not limited to welding.

[0052] Please refer to Figure 5 , a certain angle is provided between the connecting wire 302 and the reinforcing wire 301. Correspondingly, an avoidance groove is arranged at the end of the tube sleeve 100 along its distribution direction. The avoidance groove is used for the connecting wire 302 to extend out of the inside of the tube sleeve 100. The length of the avoidance groove is not specifically limited.

[0053] In the above implementation process, the reinforcing wire 301 and the connecting wire 302 are connected as a whole. Through the cooperation of the two, they can be used to bear tension and bending, ensure that the RF wire group 200 does not have large - arc bending, realize the protection of the RF wire group 200, and is beneficial to signal transmission.

[0054] In some embodiments, the reinforcing member 300 further includes a crimping head 303. The crimping head 303 includes but is not limited to aluminum material. The crimping head 303 is connected to the connecting wire 302. When the RF wire group 200 is connected and signal transmission is carried out, it can limit the RF wire group 200, play a role in protecting the RF wire group 200, and avoid damage to the RF wire group 200 when it is pulled and bent.

[0055] Both the reinforcing member 300 and the RF wire group 200 pass through the tube sleeve 100. For the reinforcing member 300 and the RF wire group 200 located inside the tube sleeve 100, the reinforcing member 300 is located outside the RF wire group 200. At the same time, during assembly, the connecting wire 302 of the reinforcing member 300 needs to be straightened, and then the crimping head 303 is pressed tightly against the connecting wire 302, and the crimping head 303 is limited in the main component 500 and the sensor unit. It should be noted that the connecting wire 302 can be formed by winding a number of thin wires and straightened, which can ensure that when the RF cable assembly is in use, the external pulling force is borne by the reinforcing member 300.

[0056] In some embodiments, the RF cable set 200 includes a connector structure 202 and a cable structure 201. The connector structure 202 is connected to the cable structure 201 for connecting to the main component 500. Both ends of the cable structure 201 extend out of the sleeve 100 for connecting to the sensor unit. The sensor unit includes a front sensor component and a rear sensor component. The front sensor component is fixed by a front sensor fixing mechanism 700, and the rear sensor component is fixed by a rear sensor fixing mechanism 600.

[0057] As Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, the connector structure 202 includes a connector part 2021, a connector sleeve 2022 and a connector magnetic ring 2023. The connector part 2021 is used to connect the cable structure 201 and the main component 500. The connector sleeve 2022 and the connector magnetic ring 2023 are sequentially sleeved on the cable structure 201, and the connector sleeve 100 and the connector magnetic ring 2023 are located at the same end of the sleeve 100, and / or the connector sleeve 2022 and the connector magnetic are located at different ends of the sleeve 100.

[0058] Exemplarily, the connector sleeve 2022 includes but is not limited to a heat shrink tube. The connector sleeve 2022 is provided with at least one group, and each group is provided with two connector sleeves 2022. In the embodiments of the present application, the connector sleeve 2022 is provided with two groups. The two groups of connector sleeves 2022 are located at the same end of the sleeve 100, and the two groups of connector sleeves 2022 are both arranged outside the sleeve 100. By arranging multiple groups of connector sleeves 2022, not only can the RF cable set 200 be protected, but also the ground wire 2017 of the RF cable set 200 can be conveniently led out between the two groups of connector sleeves 2022, avoiding the ground wire 2017 from contacting the connector part 2021 after being bent.

[0059] The connector magnetic ring 2023 is arranged inside the sleeve 100. In order to better suppress signal interference, two groups of connector magnetic rings 2023 are arranged on one side of the sleeve 100 close to the connector sleeve 2022. One group is provided with three connector magnetic rings 2023, and the other group is provided with two connector magnetic rings 2023. And on the side away from the connector sleeve 2022, one group of connector magnetic rings 2023 is arranged, that is, on this side, each sleeve 100 is provided with one connector magnetic ring 2023.

[0060] In the above implementation process, a connector sleeve 2022 and a connector magnetic ring 2023 are sleeved on the cable structure 201, so that the connector 2021 connects one end of the cable structure 201 to the host device 500, and the other end of the cable structure 201 is connected to the sensor unit. The connector sleeve 2022 can protect the cable structure 201 to avoid damage to the cable structure 201 and realize signal transmission. At the same time, under the action of the connector magnetic ring 2023, signal interference can be appropriately suppressed.

[0061] As Figure 2 shown, a plurality of the connector magnetic rings 2023 are provided, and the plurality of connector magnetic rings 2023 are distributed at both ends of the cable structure 201, which can appropriately suppress signal interference.

[0062] As Figure 4 shown, the cable structure 201 includes a radio frequency cable, and the radio frequency cable includes a core wire 2011, an inner shielding component and an outer shielding component. The inner shielding component is sleeved on the core wire 2011, and the outer shielding component is sleeved on the inner shielding component.

[0063] Exemplarily, the connector 2021 is provided with a first cylinder 20211 and a second cylinder 20212. The first cylinder 20211 includes a fine needle. The first cylinder 20211 is welded to the core wire 2011, and the second cylinder 20212 is crimped to the inner shielding component to realize the fixation of the connector 2021 to the radio frequency cable.

[0064] In the above implementation process, the core wire 2011 is used for signal transmission, and an inner shielding component is sleeved on the core wire 2011, and an outer shielding component is sleeved on the inner shielding component. Through double-layer shielding, not only can the core wire 2011 be protected, but also interference signals can be shielded, which is beneficial to the core wire 2011 for signal transmission.

[0065] In some embodiments, the inner shielding component includes an inner shielding member 2012, an inner insulating layer 2013 and an inner insulator 2014. The inner shielding member 2012 is sleeved outside the inner insulating layer 2013, and the inner insulating layer 2013 is exposed outside the inner shielding member 2012 so that the inner insulating layer 2013 protrudes more in the longitudinal direction than the inner shielding member 2012. The inner insulating layer 2013 is sleeved outside the core wire 2011, and the core wire 2011 is exposed outside the inner insulating layer 2013 so that the core wire 2011 protrudes more in the longitudinal direction than the inner insulating layer 2013. The inner insulator 2014 is sleeved outside the inner shielding member 2012, and the inner shielding member 2012 is exposed outside the inner insulator 2014 so that the inner shielding member 2012 protrudes more in the longitudinal direction than the inner insulator 2014.

[0066] Exemplarily, the length of the inner insulator 2014 is less than the length of the inner shield 2012, the length of the inner shield 2012 is less than the length of the inner insulating layer 2013, and the length of the inner insulating layer 2013 is less than the length of the core wire 2011, so that the inner shield 2012, the inner insulating layer 2013, the inner insulator 2014 and the core wire 2011 can all be exposed.

[0067] In the above implementation process, the inner shield 2012 is insulated from the core wire 2011 by the inner insulating layer 2013, and the inner shield 2012 can be used to connect with the joint 2021 (for example, both the inner shield 2012 and the inner insulator 2014 are crimped to the second cylinder 20212 of the joint 2021), which is beneficial to the stability when the core wire 2011 is connected to the joint 2021. The inner insulator 2014 is sleeved on the inner shield 2012 and can be used for insulation between the outer shield assembly and the inner shield assembly.

[0068] In some embodiments, the outer shield assembly includes an outer shield 2015 and an outer insulating layer 2016. The outer shield 2015 is sleeved outside the inner insulator 2014, and the inner insulator 2014 is exposed outside the outer shield 2015, so that the inner insulator 2014 protrudes more in the longitudinal direction from the outer shield 2015. The outer insulating layer 2016 is sleeved outside the outer shield 2015, and the outer shield 2015 is exposed outside the outer insulating layer 2016, so that the outer shield 2015 protrudes more in the longitudinal direction from the outer insulating layer 2016.

[0069] Exemplarily, the length of the outer shield 2015 is less than the length of the inner insulator 2014, and the length of the outer insulating layer 2016 is less than the length of the outer shield 2015, so that both the outer shield 2015 and the outer insulating layer 2016 can be exposed.

[0070] In the above implementation process, the cable structure 201 is grounded through the outer shield 2015. The outer insulating layer 2016 is sleeved on the outer shield 2015, which can achieve insulation between the outer shield 2015 and the outside. An inner insulator 2014 is provided between the outer shield 2015 and the inner shield 2012 to achieve insulation between the outer shield 2015 and the inner shield 2012. Through the cooperation of the outer shield 2015 and the inner shield 2012, double-layer shielding of the core wire 2011 can be achieved.

[0071] Such as Figures 1 - 2As shown, the cable structure 201 further includes a ground wire 2017 and a ground ring 2018. The ground wire 2017 is connected to the outer shield 2015, and the ground ring 2018 is connected to the ground wire 2017.

[0072] Exemplarily, the ground wire 2017 is located on the side of the sleeve 100 close to the connector 2021. One end of the ground wire 2017 is welded to the outer shield 2015, and the other end is connected to the ground ring 2018. The ground ring 2018 is used for grounding the conductive coating inside the housing of the main unit 500.

[0073] In some embodiments, the RF cable assembly further includes a connecting tube 101. The connecting tube 101 is located between the two sleeves 100 and is fixedly connected to the two sleeves 100. The length of the connecting tube 101 is not greater than the length of the sleeve 100.

[0074] Exemplarily, the connecting tube 101 is made of the same material as the sleeve 100, and the connecting tube 101 is located on the side of the sleeve 100 close to the connector 2021.

[0075] In the above implementation process, a connecting tube 101 is provided between the two sleeves 100, which can not only fix the two sleeves 100 together to prevent the two sleeves from shaking independently during use, but also avoid damage to the RF cable group 200 when the RF cable group 200 is pulled and bent after the steel wires and the RF cable group 200 are respectively arranged inside the two sleeves 100, thus playing a role in protecting the RF cable group 200.

[0076] In some embodiments, the RF cable assembly for transmitting the pulmonary edema detection signal further includes a splitter 400. The splitter 400 is connected to the sleeve 100 and the connecting tube 101. One end of the connecting tube 101 is located inside the splitter 400. A partition tube 401 is provided inside the splitter 400 for separating the two RF cable groups 200 when the two RF cable groups 200 penetrate through the splitter 400.

[0077] In the above implementation process, a splitter 400 is provided on the RF cable group 200, which is beneficial to the connection between the RF cable group 200 and the main unit 500. At the same time, a partition tube 401 is provided inside the splitter 400, which can separate the two RF cable groups 200 and provide sufficient friction to prevent the cable group from falling out of the connection position of the splitter 400.

[0078] As Figure 7 shown, in the second aspect, the present application further provides a pulmonary edema detector, including: the RF cable assembly for transmitting the pulmonary edema detection signal as described above.

[0079] In one of the application examples, the pulmonary edema measuring instrument further includes a front sensor fixing mechanism 700 and a rear sensor fixing mechanism 600. The front sensor fixing mechanism 700 is disposed on the front side (chest) of the human body. The front sensor fixing mechanism 700 is used to fix the front sensor component, and the front sensor component is used to receive the radio frequency signal emitted by the rear sensor component located on the rear side (back) of the human body. The radio frequency component is respectively connected to the front sensor component and the rear sensor component to form an interaction of radio frequency signals. The front sensor component and the rear sensor component are controlled by the main component 500. For example, when measuring pulmonary edema, the two sensor units are respectively worn on the rear side and the front side of the human body corresponding to the positions of the human lung lobes. By emitting radio frequency signals to the lung lobes and then receiving the radio frequency signals after passing through the lung lobes, one or more biological parameters are calculated and / or measured according to the dielectric-related properties of organs or tissues, and then the current pulmonary edema content is measured. There are many application examples in the prior art for the method of using radio frequency or microwave radiation for monitoring and diagnosing body tissues, which will not be elaborated here.

[0080] Compared with the traditional measurement method, during the whole measurement process of the solution of this embodiment, there is no need for the patient to perform additional operations of inhaling and exhaling auxiliary gas. The measurement process is simpler and more efficient, and there will be no disposable consumables, and the application cost is also lower.

[0081] Since the pulmonary edema detector provided in the second aspect includes a radio frequency cable assembly for transmitting pulmonary edema detection signals, the pulmonary edema detector has all the technical effects of the radio frequency cable assembly for transmitting pulmonary edema detection signals, which will not be elaborated here.
