[0032] Please refer to Figures 1 to 2, the binding component 1 includes a fixing part 11, a strap 12 connecting the fixing part 11, and an elastic band 13. The fixing part 11 is made of flexible materials such as cloth, plastic, etc., and is in an inverted triangular state. The fastening part 2 is fixed to the inner surface of the fixing part 11. The strap 12 is fixedly installed at the top of the fixing part 11 and is elastic. One end of the strap 12 is fixedly connected to the fixing part 11, and the other end surrounds the waist position of the human body and then adheres or locks to the outer surface of the fixing part 11. The elastic band 13 is fixedly installed at the bottom of the fixing part 11 and is elastic. One end of the elastic band 13 is fixedly connected to the fixing part 11, and the other end adheres or locks to the strap 12 located at the waist via the inner side of the human thigh and the buttocks.

[0033] Please refer to Figures 3 to 4 , on the side of the fastening part 2 facing the human body, a liquid collecting cavity 21 is formed by inward depression from its surface. The liquid collecting cavity 21 is used to hold urine. The side of the fastening part 2 facing the human body has a curvature adapted to the human body surface, and this surface is wrapped with soft glue. A protrusion 22 is formed outward from the above-mentioned curved surface at its bottom. The protrusion 22, the above-mentioned curvature, and the wrapped soft glue can be closely attached to the human body surface.

[0034] Furthermore, the curvature adapted to the human body surface and the protrusion 22 have different shapes and options according to the physiological differences between men and women to fit the human body.

[0035] On the other side of the fastening part 2, a docking part 23 is provided. One end of the docking part 23 is fixedly connected to the fastening part 2, and the other end extends horizontally outward. The outer surface of the docking part 23 is attached to the inner surface of the fixing part 11. The docking part 23 and the fixing part 11 are fixedly connected by sequentially passing through the docking part 23 and the fixing part 11 with bolts or screws, etc. The docking part 23 is in a horizontal state.

[0036] A limiting part 24 is provided in the liquid collecting cavity 21. The number of the limiting parts 24 is a pair and they are arranged oppositely. They are installed on the inner wall of the fastening part 2. The surface of the limiting part 24 is inwardly depressed to form a receiving groove 25. The receiving groove 25 is used to receive the sensing structure 4 and limit the position of the sensing structure 4.

[0037] Please refer to Figure 4 , one end of the liquid guiding pipe 3 penetrates the fastening part 2 and extends into the liquid collecting cavity 21, and its end extends to the bottom of the liquid collecting cavity 21. The other end of the liquid guiding pipe 3 is connected to the liquid pumping pump 5. The number of the liquid guiding pipes 3 can be changed according to requirements. In this embodiment, the number of the liquid guiding pipes 3 is a pair and they are arranged oppositely.

[0038] Please refer to Figure 4, the sensing structure 4 includes a first sensing member 41 and a second sensing member 42. One end of both the first sensing member 41 and the second sensing member 42 penetrates through the fastening portion 2 and extends into the liquid collection chamber 21. They are fixed by the limiting member 24, and their ends extend into the liquid collection chamber 21. The other ends of the first sensing member 41 and the second sensing member 42 are connected to the liquid extraction pump 5. Preferably, the ends of the first sensing member 41 and the second sensing member 42 extending into the liquid collection chamber 21 extend in different directions, that is, the distance between the ends of the first sensing member 41 and the second sensing member 42 is relatively large, and the first sensing member 41 and the second sensing member 42 cannot hang liquid, resulting in the series connection of the first sensing member 41 and the second sensing member 42. Further, the first sensing member 41 is supported by the limiting member 24 and is suspended within the fastening portion 2.

[0039] The first sensing member 41 has the same structure as the first sensing member 41. It includes a conductive layer 43 and an insulating layer 44. The conductive layer 43 is made of a conductive material, and the insulating layer 44 wraps the conductive layer 43. The conductive layer 43 is only exposed at the end portion.

[0040] The number of the sensing structures 4 can be changed according to requirements, and it corresponds to the liquid guiding pipeline 3. In this embodiment, the number of the sensing structures 4 is a pair and they are arranged oppositely to adapt to different directions when the user lies on the side.

[0041] The length of the liquid guiding pipeline 3 extending into the liquid collection chamber 21 is greater than the length of the sensing structure 4 extending into the liquid collection chamber 21.

[0042] Please refer to Figure 6 , the liquid extraction pump 5 is provided with a sensing element 51 and a pump body 52. The sensing element 51 can sense whether the first sensing member 41 and the first sensing member 41 are energized to judge whether there is liquid in the liquid collection chamber 21. The sensing element 51 starts the pump body 52 to extract liquid through the liquid guiding pipeline 3. When the first sensing member 41 and the first sensing member 41 are not in contact with the liquid, the pump body 52 extracts liquid through the liquid guiding pipeline 3 for a period of time to reduce the remaining liquid in the liquid collection chamber 21.

[0043] The liquid extraction pump 5 has a liquid guiding interface 53 and a signal interface 54. The liquid guiding interface 53 is plugged and connected to the liquid guiding pipeline 3, and the signal interface 54 is plugged and connected to the sensing structure, and the liquid guiding pipeline 3 and the sensing structure 4 can be replaced according to requirements.

[0044] When the wearable external urinary catheter device of the present utility model is in use, one end of the strap 12 is fixedly connected to the fixing part 11, and the other end is wound around the waist position of the human body and then adhered or locked to the outer surface of the fixing part 11. The elastic band 13 is fixedly installed at the bottom of the fixing part 11 and has elasticity. One end of the elastic band 13 is fixedly connected to the fixing part 11, and the other end is adhered or locked to the strap 12 located at the waist via the inner thigh and buttocks of the human body. The strap 12 and the elastic band 13 press the fastening part 2 against the human body surface through elasticity, so that the fastening part 2 is closely attached to the human body surface. At this time, the urinary organ is covered by the fastening part 2. After urination, the liquid flows into the liquid collecting cavity 21. The first sensing element 41 and the second sensing element 42 come into contact with the liquid. The liquid has conductivity, and the first sensing element 41 and the second sensing element 42 are connected. The sensing element 51 determines that there is liquid in the liquid collecting cavity 21 and starts the pump body 52 to pump the liquid through the liquid guiding pipe 3.

[0045] The present utility model relates to a wearable external urinary catheter device, which has the characteristics of simple operation and wide applicability. The fastening part is pressed against the human body surface through the binding assembly, so that the fastening part is closely attached to the human body surface, optimizing the wearing process. Then, by arranging a plurality of sensing structures and liquid guiding pipes in the liquid collecting cavity, it can meet the urination in different body positions, expanding the applicable population and increasing the applicability.

[0046] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
