DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figures 1 to 6 As shown, a drainage tube for oncology that is not easy to be blocked comprises a drainage tube body 1, a receiving tube 2 is fixedly connected to the outer wall of the top of the drainage tube body 1, a cleaning column 3 is slidably connected in the receiving tube 2, a fixing ring 4 is fixedly connected to the upper and lower ends of the cleaning column 3, a lower connecting ring 5 is sleeved on the fixing ring 4 located at the bottom, a metal wire rope 6 is fixedly connected to the outer wall of the lower connecting ring 5, the outer wall of the metal wire rope 6 is fitted with the inner wall of the drainage tube body 1, a connecting block 7 is fixedly connected to the outer wall of the bottom of the drainage tube body 1, a connecting hole 8 is opened in the middle of the connecting block 7, one end of the metal wire rope 6 passes through the connecting hole 8 and is fixedly connected to a connecting ball 9, an upper connecting ring 10 is sleeved on the fixing ring 4 at the upper end of the cleaning column 3, a metal pull rope 11 is fixedly connected to the outer wall of the upper connecting ring 10, one end of the metal pull rope 11 passes through the receiving tube 2 and is fixedly connected to the moving block, and the length of the metal pull rope 11 is not less than the length of the metal wire rope 6.

[0024] like Figure 1 As shown, the utility model is a non-blocking tumor internal medicine drainage tube with a similar structure to the existing drainage tube, such as the anti-blocking drainage tube disclosed in the patent with publication number CN219878908U. The main improvement of the utility model is that the drainage tube can be cleared multiple times, such as Figures 1 to 6As shown, when a drainage tube for oncology that is not easy to be blocked in the utility model is in use, when a blockage occurs in the drainage tube body 1, the user can pull the connecting ball 9 to drive the metal wire rope 6, and the metal wire rope 6 further drives the cleaning column 3 to move. The cleaning column 3 enters the drainage tube body 1 from the receiving tube 2 under the pull of the metal wire rope 6, and then contacts the blockage in the drainage tube body 1 and hits the blockage, thereby clearing the blockage of the drainage tube body 1 and keeping the drainage tube body 1 unobstructed. Then the user pulls the moving block, and the moving block drives the metal pull rope 11, and the metal pull rope 11 further pulls the cleaning column 3, so that The cleaning column 3 rises, and then the user uses the hand to deform the drainage tube body 1 and the storage tube 2, so that the drainage tube body 1 and the storage tube 2 are in a straight line, and then continues to pull the moving block to move the cleaning column 3 into the storage tube 2, thereby resetting the cleaning column 3, making it convenient for the cleaning column 3 to perform the next blockage clearing work, and at the same time avoiding the cleaning column 3 from affecting the flow of the drainage tube body 1; the connecting ball 9 and the moving block can prevent the metal wire rope 6 and the metal pull rope 11 from being pulled into the drainage tube body 1, avoiding the cleaning column 3 from being unusable, and at the same time can also facilitate the user to pull the metal wire rope 6 and the metal pull rope 11, thereby improving the user experience.

[0025] By arranging the metal wire rope 6 and the metal pull rope 11 on the cleaning column 3, and utilizing the mutual cooperation of the metal wire rope 6 and the metal pull rope 11, the cleaning column 3 can move back and forth in the drainage tube body 1, thereby realizing multiple cleaning of the blockage in the drainage tube body 1. Compared with the original technology, the cleaning effect of the drainage tube body 1 is improved, and the problem of re-clogging of the cleared area that cannot be solved is avoided.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the moving block is set as a connecting cap 12, the inner wall of the connecting cap 12 is in contact with the outer wall of the storage tube 2, a connecting groove 16 is opened in the connecting cap 12, one end of the metal pull rope 11 is fixedly connected to the inner wall of the connecting groove 16, and the metal pull rope 11 is placed in the connecting groove 16 in a spiral shape.

[0027] Specifically, the connecting cap 12 can provide storage for the metal pull rope 11 while making it convenient for the user to pull the metal pull rope 11, thereby preventing the metal pull rope 11 from affecting the patient's daily life. At the same time, it can also prevent the drainage tube body 1 from leaking from the storage tube 2, thereby improving the practicality of the metal pull rope 11.

[0028] like Figure 2 and Figure 3 As shown, a plurality of bristles 13 are fixedly connected to the outer wall of the cleaning column 3 at equal intervals, and the bristles 13 are disc-shaped.

[0029] Specifically, the bristles 13 enable the cleaning column 3 to clean the inner wall of the drainage tube body 1 when it moves, preventing foreign matter from adhering to the inner wall of the drainage tube body 1 and causing subsequent blockage, thereby improving the clearing ability of the cleaning column 3.

[0030] like Figure 2 and Figure 3 As shown, a conical block 14 is fixedly connected to the lower end of the cleaning column 3 , and a fixing ring 4 is fixedly connected to the tip of the conical block 14 .

[0031] Specifically, by utilizing the tip of the conical block 14 , the cleaning column 3 can more quickly knock away the blockage when clearing the blockage, thereby clearing the blockage more quickly, and further improving the clearing efficiency of the cleaning column 3 .

[0032] like Figure 3 and Figure 5 As shown, a clamping block 15 is fixedly connected to the outer wall of the connecting ball 9 , and the clamping block 15 corresponds to the position of the connecting hole 8 .

[0033] Specifically, the clamping block 15 is made of elastic material such as silicone, rubber, etc., and can provide sealing for the connecting hole 8 to prevent liquid from flowing out of the connecting hole 8.

[0034] like Figure 4 As shown, a plurality of clamping rings 17 are fixedly connected to the inner wall of the connecting groove 16 , and the outer wall of the clamping ring 17 fits with the inner wall of the receiving tube 2 .

[0035] Specifically, the clamping ring 17 can facilitate the fixation between the connecting cap 12 and the storage tube 2 , and can prevent the connecting cap 12 from falling off to expose the metal pull rope 11 , thereby improving the stability of the connecting cap 12 .

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
