Description

Technical Field

[0001] The utility model relates to the technical field of drainage catheters, in particular to a flushing drainage catheter. Background Art

[0002] A flushing drainage catheter refers to cleaning the drainage pipeline to keep it unobstructed and prevent infection. The drainage catheter is usually used in surgeries or medical procedures to drain excess fluid or gas from the body.

[0003] A relatively long flexible catheter is provided on the drainage catheter. However, the existing drainage catheters do not have the function of storing the catheter, which is not conducive to the storage of the drainage catheter. It is difficult to effectively store the catheter without this function when not in use, increasing the difficulty of storage and carrying.

[0004] Therefore, it is necessary to design a flushing drainage catheter to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a flushing drainage catheter to solve the deficiencies existing in the prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A flushing drainage catheter, comprising a pipe joint, a catheter connected to the pipe joint, and further comprising:

[0008] Two winding rods, both fixed on the pipe joint;

[0009] A limiting structure, arranged on the pipe joint, for providing limitation to the stored catheter;

[0010] A positioning structure, arranged on one of the winding rods.

[0011] As a preferred technical solution of the utility model, the limiting structure comprises:

[0012] A shaft rod, fixed on the pipe joint;

[0013] A rotating plate, with a through hole opened at one end, and the shaft rod passes through the through hole and is movably inserted into the through hole;

[0014] A limiting cap, fixed on the end of the shaft rod away from the pipe joint;

[0015] Two openings, both opened on the rotating plate.

[0016] As a preferred technical solution of the utility model, the positioning structure comprises:

[0017] A through port, opened on the winding rod;

[0018] Two bumps are respectively fixed at both ends of the through port.

[0019] As a preferred technical solution of the present utility model, the bump has a hemispherical structure, and the end position of the bump extends to the outside of the through port, and the bump is made of a flexible material.

[0020] As a preferred technical solution of the present utility model, the cross-sectional diameter of the opening is larger than the cross-sectional diameter of the winding rod.

[0021] The present utility model has the following beneficial effects:

[0022] 1. Convenient storage: By winding the catheter around the two winding rods, the catheter can be effectively sorted and stored, reducing clutter.

[0023] 2. Stable fixation: The rotating plate can firmly fix the winding rod, preventing the catheter from loosening during storage, and ensuring the neatness and stability of the catheter.

[0024] 3. Protect the catheter: Friction and the positioning structure help prevent the catheter from being damaged or deformed during storage, extending the service life of the catheter. Description of the Drawings

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0031] Refer to Figures 1-4, A flushing and drainage catheter, comprising a tube connector 1, a catheter 2 is connected to the tube connector 1, and further comprising: two wire winding rods 3, both fixed on the tube connector 1, and two wire winding rods 3 arranged opposite to each other are provided on the tube connector 1. When the catheter 2 needs to be stored, the staff can wind the catheter 2 in a figure-eight shape around the two wire winding rods 3, and the storage of the catheter 2 can be realized;

[0032] The drainage catheter further comprises a limiting structure, which is arranged on the tube connector 1 and is used to provide limitation for the stored catheter 2. The limiting structure comprises: a shaft rod 41, fixed on the tube connector 1; a rotating plate 42, with a through hole opened at one end, the shaft rod 41 passes through the through hole and is movably inserted into the through hole; a limiting cap 43, fixed at the end of the shaft rod 41 away from the tube connector 1; two openings 44, both opened on the rotating plate 42, the cross-sectional diameter of the opening 44 is larger than the cross-sectional diameter of the wire winding rod 3. After the storage is completed, the staff rotates the rotating plate 42 so that the two openings 44 on the rotating plate 42 are respectively opposite to the two wire winding rods 3, and then presses the rotating plate 42 to make the rotating plate 42 move towards the direction close to the tube connector 1. At this time, the two wire winding rods 3 will respectively pass through the two openings 44;

[0033] The drainage catheter further comprises a positioning structure, which is arranged on one of the wire winding rods 3. The positioning structure comprises: a through hole 51, opened on the wire winding rod 3; two convex blocks 52, respectively fixed at both ends of the through hole 51. The convex blocks 52 are in a hemispherical structure, and the end positions of the convex blocks 52 extend to the outside of the through hole 51. The convex blocks 52 are made of flexible materials. For the positioning structure, when the two wire winding rods 3 pass through the two openings 44, one of the openings 44 will squeeze the end positions of the two convex blocks 52, causing the two convex blocks 52 to deform. When both convex blocks 52 move into the opening 44, the two convex blocks 52 can jointly resist the opening 44 and fix the rotating plate 42 by using friction, so as to fix the position of the rotating plate 42. At this time, the rotating plate 42 can block the catheter 2 wound on the two wire winding rods 3, provide limitation for the catheter 2, and prevent the catheter 2 from spreading from the two wire winding rods 3, thereby ensuring the storage effect of the catheter 2.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
