Description

Technical Field

[0001] It relates to the technical field of medical devices, and particularly to an external urinary catheterization device. Background Art

[0002] For the problem of difficult urination in patients with limited mobility, a urinary catheter is usually used to assist the patient to solve the problem.

[0003] According to Chinese Patent CN215875168U, a urinary catheter is disclosed. The urinary catheter includes a urine sleeve and two urine bags. The urine sleeve is an integrally formed flexible sleeve body. Two opposite catheter tubes are convexly provided on the outer sides of the bottom end of the urine sleeve. The urine bag is connected to the catheter tube through a catheter connector to guide and collect urine. The urinary catheter relies on the gravity of urine to naturally flow into the catheter tube, but there will still be residues in the urine sleeve. When the urinary catheter is removed, urine leakage occurs.

[0004] In view of the above-mentioned disadvantages of the urinary catheter, an automatic urinary catheterization device has emerged. Utilizing the electrical conductivity of urine, the urine in the urine sleeve is discharged. However, the activity range of patients with limited mobility is limited, such as patients who cannot stand or sit. When these patients urinate, the urine in the urine sleeve is stored at different positions. When the automatic urinary catheterization device extracts urine, residues remain in the urine sleeve. Secondly, the automatic urinary catheterization device uses its electrical conductivity for induction. When residues occur or hanging liquid occurs in the induction area, it causes the automatic urinary catheterization device to pump air in vain.

[0005] Therefore, it is necessary to develop an external urinary catheterization device to solve the above problems. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide an external urinary catheterization device that reduces urine residues and avoids air pumping in vain.

[0007] To achieve the above purpose, the present utility model provides the following technical solution: An external urinary catheterization device, which includes:

[0008] A connection part, including a snap ring and a blocking part connected to the snap ring and adapted to the patient's urinary organ;

[0009] A temporary storage part, tightly docked with the connection part, a cavity is formed in the temporary storage part, and the cavity can store liquid;

[0010] A liquid guiding pipeline, extending into the cavity, for sucking the liquid in the cavity;

[0011] An induction structure, which includes a first induction part and a second induction part with electrical conductivity. The first induction part and the second induction part extend into the cavity, and their ends extend in different directions. The first induction part and the second induction part contact the liquid to form a series connection and transmit information;

[0012] The liquid extraction pump receives the above information and extracts liquid through the liquid guiding pipeline.

[0013] Furthermore, the first sensing member and the second sensing member have the same structure, which includes a conductive layer and an insulating layer. The conductive layer is made of a conductive material, and the insulating layer wraps the conductive layer.

[0014] Furthermore, the ends of the first sensing member and the second sensing member expose the conductive layer.

[0015] Furthermore, the number of the sensing structures and the liquid guiding pipelines is one pair and they are arranged oppositely.

[0016] Furthermore, the length of the liquid guiding pipeline is greater than the length of the sensing structure.

[0017] Furthermore, a limiting member is provided in the cavity. The number of the limiting members is one pair and they are arranged oppositely. They are installed on the inner wall of the temporary storage part. The limiting member is recessed inward from its surface to form a receiving groove, and the receiving groove is used to receive and fix the liquid guiding pipeline and the sensing structure.

[0018] Furthermore, the receiving groove limits the positions of the liquid guiding pipeline and the sensing structure, so that the liquid guiding pipeline and the sensing structure extend vertically downward.

[0019] Furthermore, the connecting part has a liquid storage cavity, and the liquid storage cavity is communicated with the cavity and can temporarily store liquid.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model is an external urinary catheterization device, which has the characteristics of reducing urine residue and avoiding empty extraction. Through the cooperation of the locking ring and the locking buckle, the temporary storage part is fixed on the patient. A plurality of sensing structures and liquid guiding pipelines are arranged in the temporary storage part and the liquid storage cavity to meet urination in different body positions, reduce the residue in the temporary storage part and the liquid storage cavity. At the same time, the bifurcated setting of the first sensing member and the second sensing member avoids empty extraction caused by the hanging liquid phenomenon. Description of the Drawings

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 to 4 , the present invention is an external urinary catheterization device, which includes a connection part 1, a temporary storage part 2 docked with the connection part 1, a liquid guide pipeline 3 connecting the temporary storage part 2, an induction structure 4, and a liquid extraction pump 5 provided at the ends of the liquid guide pipeline 3 and the induction structure 4.

[0029] Please refer to Figures 1 to 2 , the connection part 1 includes a snap ring 11 and an outer ring 12. The snap ring 11 has a flow blocking part 111. The flow blocking part 111 is provided with a through hole for receiving the genitals. The flow blocking part 111 is made of a flexible material, such as rubber, silica gel, etc., and can closely fit the human body. A connection ring 112 is provided on its outer side. The connection ring 112 is used for tightly connecting with the outer ring 12. A liquid storage cavity 13 is formed between the flow blocking part 111 and the outer ring 12.

[0030] The outer ring 12 is made of hard rubber. Its bottom extends into the liquid storage cavity 13, so that the inner side of the connection ring 112 fits with the outer ring 12 and is bonded by glue, so that liquid cannot flow out from the connection part. Both the snap ring 11 and the outer ring 12 have openings, and a locking buckle 14 is provided at the opening.

[0031] The outer surface of the outer ring 12 is provided with a clamping groove. The connecting part 1 further includes a locking ring 15. The locking ring 15 is installed in the temporary storage part 2. By rotating clockwise, the locking ring 15 is locked with the outer ring 12 to prevent liquid from flowing out. The diameter of the liquid blocking part 111 can be selected in different specifications according to requirements to adapt to genitals of different sizes. When the liquid blocking part 111 fits on the genital, it is fixed by the locking buckle 14.

[0032] The liquid storage cavity 13 is located inside the connecting ring 112. Since both the clamping ring 11 and the connecting ring 112 have a certain height, the liquid storage cavity 13 can temporarily store liquid.

[0033] Please refer to Figure 3 , the temporary storage part 2 is sleeved on the connecting part 1. It is recessed inward from the lower surface to form a cavity 21. The outer ring 12 can extend into the cavity 21. The liquid storage cavity 13 is communicated with the cavity 21. The connecting part 1 and the temporary storage part 2 are tightly connected to prevent liquid from seeping out from the connection.

[0034] A limiting member 22 is arranged in the cavity 21. The number of the limiting members 22 is a pair and they are arranged oppositely. They are installed on the inner wall of the temporary storage part 2. The limiting member 22 is recessed inward from its surface to form a receiving groove 23. The receiving groove 23 is used to receive the liquid guiding pipe 3 and the sensing structure 4 and limit the positions of the liquid guiding pipe 3 and the sensing structure 4, so that the liquid guiding pipe 3 and the sensing structure 4 extend vertically downward.

[0035] Please refer to Figure 1 and Figure 3 , one end of the liquid guiding pipe 3 penetrates through the temporary storage part 2 and extends into the cavity 21. It is fixed by the limiting member 22. Its end extends into the liquid storage cavity 13. 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.

[0036] Please refer to Figure 1 and Figure 3 , the sensing structure 4 includes a first sensing member 41 and a second sensing member 42. Both the first sensing member 41 and the second sensing member 42 penetrate through the temporary storage part 2 at one end and extend into the cavity 21. They are fixed by the limiting member 22. Their ends extend into the liquid storage cavity 13. The other ends of the first sensing member 41 and the second sensing member 42 are connected to the liquid pumping pump 5. Preferably, the ends of the first sensing member 41 and the second sensing member 42 extending into the liquid storage cavity 13 extend in different directions, that is, the distance between the ends of the first sensing member 41 and the second sensing member 42 is larger. 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.

[0037] 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 conductive material. The insulating layer 44 wraps the conductive layer 43. Only the part of the conductive layer 43 located in the liquid storage cavity 13 is exposed.

[0038] The number of the induction structures 4 is changed according to requirements, and it corresponds to the liquid guiding pipeline 3. In this embodiment, the number of the induction structures 4 is a pair and they are arranged oppositely to adapt to different directions when the user lies on the side.

[0039] The length of the liquid guiding pipeline 3 extending into the liquid storage cavity 13 is greater than the length of the induction structure 4 extending into the liquid storage cavity 13.

[0040] Please refer to Figure 4 , the liquid extraction pump 5 is provided with an induction element 51 and a pump body 52. The induction element 51 can sense whether the first induction part 41 and the first induction part 41 are electrified to judge whether there is liquid in the liquid storage cavity 13 and the temporary storage part 2. The induction element 51 starts the pump body 52 to extract liquid through the liquid guiding pipeline 3. When the first induction part 41 and the first induction part 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 storage cavity 13 and the temporary storage part 2.

[0041] The liquid extraction pump 5 has a liquid guiding interface 53 and a signal interface 54. The liquid guiding interface 53 and the liquid guiding pipeline 3 are plugged and connected, and the signal interface 54 and the induction structure are plugged and connected, and the liquid guiding pipeline 3 and the induction structure 4 can be replaced according to requirements.

[0042] When the external urinary catheterization device of the present utility model is in use, the genital organ extends into the flow blocking part 111, the flow blocking part 111 fits on the genital organ, and then it is fixed through the locking buckle 14. Rotate the locking ring 15 clockwise. When it rotates to an appropriate angle, the locking ring is locked and fixed with the card slot of the outer ring 12, so that the locking ring 15 presses the outer ring soft glue of the flow blocking part 111 downward for sealing. After urination, the liquid flows into the liquid storage cavity 13 and the temporary storage part 2. The first induction part 41 and the second induction part 42 contact the liquid. The liquid has conductivity, the first induction part 41 and the second induction part 42 are connected, and the induction element 51 judges that there is liquid in the liquid storage cavity 13 and the temporary storage part 2 and starts the pump body 52 to extract liquid through the liquid guiding pipeline 3.

[0043] The present utility model is an external urinary catheterization device, which has the characteristics of reducing urine residue and avoiding empty extraction. Through the cooperation of the locking ring and the locking buckle, the temporary storage part is fixed on the patient. A plurality of induction structures and liquid guiding pipelines are arranged in the temporary storage part and the liquid storage cavity to meet urination in different body positions, reduce the residue in the temporary storage part and the liquid storage cavity, and at the same time, the forked arrangement of the first induction part and the second induction part avoids empty extraction caused by the hanging liquid phenomenon.

[0044] The above are only the preferred specific embodiments 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 substitutions or changes, and all should be covered within the protection scope of the present utility model.
