[0002] Surgical drainage is a simple and effective surgical treatment method, which plays an irreplaceable role in various infectious and hemorrhagic diseases. Due to the characteristics of the human urinary system organs being a hollow urine drainage system, once there is an obstacle in urine drainage in the case of trauma, disease or postoperative state, it will greatly increase the chance of urinary system infection, and even affect the renal function of the patient seriously in severe cases. Therefore, it is particularly important to flush and drain the urinary tract lumen.

[0003] When the existing drainage tube is in use, if there is dirt in the drainage substance and the diameter of the drainage tube is relatively fixed at this time, it will easily cause the drainage tube to be blocked during the drainage process. Content of the Utility Model

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] 1. In the present utility model, by providing an expansion device, when the inner wall of the drainage tube body needs to be expanded when the drainage tube body is blocked by dirt, first connect the connecting pipe to an air injection device, then open the valve, and the gas enters the inside of the air delivery pipe through the connecting pipe and then enters the annular airbag from the inside of the air delivery pipe, so that the annular airbag can be inflated. As the annular airbag expands, it drives the connecting rod to move outward. The outward movement of the connecting rod drives the expansion plate to move outward. The outward movement of the expansion plate can expand the inner wall of the drainage tube body, enabling the dirt in the drainage substance to be smoothly discharged from the drainage tube body, avoiding blockage of the drainage tube body. Through the cooperation of the above structures, the expansion plate can expand the inner wall of the drainage tube, preventing the drainage tube body from being blocked during drainage.

[0013] 2. In the present utility model, by providing a sealing device, when the connecting pipe is not in use, first pull the pull rod. The movement of the pull rod drives the moving plate to move on the surface of the sliding rod. The movement of the moving plate on the surface of the sliding rod will compress the spring, causing the spring to be compressed under force. At the same time, the movement of the moving plate on the surface of the sliding rod also drives the insertion rod to move. When the insertion rod moves out of the installation groove, then place the installation plate inside the installation groove. When the installation plate enters the installation groove, the U-shaped rod drives the sealing plate into the connecting pipe. When the sealing plate is located inside the connecting pipe, release the pull rod. Utilize the resilience of the spring to reset the insertion rod. The reset of the insertion rod causes it to insert into the insertion hole. The insertion rod and the insertion hole are inserted together, thereby limiting the installation plate inside the installation groove. Through the cooperation of the above structure, the sealing plate can seal the connecting pipe, preventing external dust from entering the connecting pipe and blocking the connecting pipe when the connecting pipe is idle.

However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a urinary drainage tube that is convenient for expansion, including a drainage tube body 1, and an expansion device 2 is provided on the bottom surface of the drainage tube body 1.

[0023] Specifically described below are the specific settings and functions of its expansion device 2 and sealing device 3.

[0024] In this embodiment: The expansion device 2 includes a support plate 21, the support plate 21 is fixedly installed on the bottom surface of the drainage tube body 1, an air delivery pipe 22 is fixedly installed on the surface of the support plate 21, a connecting pipe 23 is fixedly installed at one end port of the air delivery pipe 22, and a valve 24 is fixedly installed on the outer wall surface of the connecting pipe 23.

[0025] In this embodiment: The setting of the support plate 21 serves to support the air delivery pipe 22.

[0026] Specifically, an annular airbag 25 is fixedly installed on the surface of the air delivery pipe 22 away from the connecting pipe 23, and a plurality of connecting rods 26 are fixedly installed on the outer wall surface of the annular airbag 25.

[0027] In this embodiment; the settings of the air delivery pipe 22 and the connecting pipe 23 serve to facilitate the inflation of the annular airbag 25.

[0028] Specifically, the plurality of connecting rods 26 are arranged at equal intervals along the outer circumference of the annular airbag (25), and an expansion plate 27 is fixedly installed on the surface of the connecting rod 26 away from the annular airbag 25. The setting of the expansion plate 27 serves to expand the inner wall of the drainage tube body 1.

[0029] In this embodiment: A sealing device 3 is provided on the outer wall surface of the connecting pipe 23. The sealing device 3 includes an extension plate 301 which is fixedly installed on the outer wall surface of the connecting pipe 23. An installation groove 302 is formed on the surface of the extension plate 301. An installation plate 303 is movably installed inside the installation groove 302. A U-shaped rod 304 is fixedly installed on the top surface of the installation plate 303. A sealing plate 305 is fixedly installed at one end of the U-shaped rod 304 away from the installation plate 303. When the connecting pipe 23 is not in use, first pull the pull rod 310. The movement of the pull rod 310 drives the moving plate 307 to move on the surface of the sliding rod 306. The movement of the moving plate 307 on the surface of the sliding rod 306 will compress the spring 312, causing the spring 312 to be compressed under force. At the same time, the movement of the moving plate 307 on the surface of the sliding rod 306 also drives the insertion rod 308 to move. When the insertion rod 308 moves out of the inside of the installation groove 302, at this time, place the installation plate 303 inside the installation groove 302. When the installation plate 303 enters the inside of the installation groove 302, the U-shaped rod 304 drives the sealing plate 305 to enter the inside of the connecting pipe 23. When the sealing plate 305 is located inside the connecting pipe 23, release the pull rod 310. Utilize the resilience of the spring 312 to reset the insertion rod 308. The reset of the insertion rod 308 causes it to insert into the inside of the insertion hole 309. The insertion rod 308 and the insertion hole 309 are inserted and connected, thereby limiting the installation plate 303 inside the installation groove 302. Through the cooperation of the above structures, the sealing plate 305 can seal the connecting pipe 23, avoiding external dust from entering the inside of the connecting pipe 23 and blocking the connecting pipe 23 when the connecting pipe 23 is idle.

[0030] Specifically, a sliding rod 306 is fixedly installed on the side surface of the extension plate 301. A moving plate 307 is slidably connected to the surface of the sliding rod 306. An insertion rod 308 is fixedly installed on the surface of the moving plate 307. An insertion hole 309 is formed on the side surface of the installation plate 303.

[0031] In this embodiment: The arrangement of the insertion rod 308 and the insertion hole 309 serves to limit the installation plate 303 inside the installation groove 302.

[0032] Specifically, a pull rod 310 is fixedly installed on the surface of one end of the moving plate 307 away from the insertion rod 308. A limiting plate 311 is fixedly installed on the surface of one end of the sliding rod 306 away from the extension plate 301. A spring 312 is fixedly installed between the limiting plate 311 and the moving plate 307.

[0033] In this embodiment: The arrangement of the spring 312 serves to limit the position of the moving plate 307 on the surface of the sliding rod 306.

[0034] Working principle: When the inner wall of the drainage tube body 1 needs to be expanded when the drainage tube body 1 is blocked by dirt, first connect the connecting tube 23 to the air injection device, then open the valve 24. The gas enters the inside of the air delivery tube 22 through the connecting tube 23 and then enters the annular airbag 25 from the inside of the air delivery tube 22, so that the annular airbag 25 can be inflated. As the annular airbag 25 expands, it drives the connecting rod 26 to move outward. The outward movement of the connecting rod 26 drives the expansion plate 27 to move outward. The outward movement of the expansion plate 27 can expand the inner wall of the drainage tube body 1, enabling the dirt in the drainage substance to be smoothly discharged from the drainage tube body 1, avoiding blockage of the drainage tube body 1. Through the cooperation of the above structures, the expansion plate 27 can expand the inner wall of the drainage tube, preventing the drainage tube body 1 from being blocked during drainage. When the connecting tube 23 is not in use, first pull the pull rod 310. The movement of the pull rod 310 drives the moving plate 307 to move on the surface of the sliding rod 306. The movement of the moving plate 307 on the surface of the sliding rod 306 will compress the spring 312, causing the spring 312 to be compressed under force. At the same time, the movement of the moving plate 307 on the surface of the sliding rod 306 also drives the insertion rod 308 to move. When the insertion rod 308 moves out of the installation groove 302, then place the mounting plate 303 inside the installation groove 302. When the mounting plate 303 enters the installation groove 302, the U-shaped rod 304 drives the sealing plate 305 into the inside of the connecting tube 23. When the sealing plate 305 is located inside the connecting tube 23, release the pull rod 310. Use the resilience of the spring 312 to reset the insertion rod 308. The reset of the insertion rod 308 causes it to insert into the insertion hole 309. The insertion rod 308 and the insertion hole 309 are inserted together, thereby limiting the mounting plate 303 inside the installation groove 302. Through the cooperation of the above structures, the sealing plate 305 can seal the connecting tube 23, preventing external dust from entering the inside of the connecting tube 23 and blocking the connecting tube 23 when it is idle.
