The sealing capsule 301 is an elastic rubber capsule. The inflation tube 302 is arranged inside the sealing capsule 301 for connecting the catheter 1 and the sealing capsule 301. The sealing valve 304 is arranged inside the sealing capsule 301 and between the urine discharge hole 305 and the inflation tube 302. In use, the catheter 1 is inserted into the urethra, then the sealing valve 304 is closed and the inflation valve 303 is opened, and the catheter 1 is further inflated. The gas enters the sealing capsule 301 through the catheter 1 and the inflation tube 302, so that the sealing capsule 301 expands and contacts the inner wall of the urethra to form a sealing fixation. After the catheter 1 is fixed, the inflation valve 303 is closed and the sealing valve 304 is opened, so that the urine in the urethra can enter the catheter 1 through the urine discharge hole 305 and further flow into the urine storage bag 2 for storage. The bottom surface of the sealing capsule 301 is conical and recessed downward to form a conical recess. The urine discharge hole 305 is arranged in the conical recess and close to the sealing capsule 301, so as to avoid the retention of urine in the urethra as much as possible, thereby effectively reducing the risk of urine leakage, improving the practicality, and being more convenient to use and promote.

[0026] Please refer to Figures 4 to 5In the embodiment, the leakage prevention mechanism 4 comprises a top plate 401 fixed between the inner walls of the urine storage bag 2, the bottom end of the urinary catheter 1 is provided with a urine outlet hole 402, a top rod 403 is slidably connected in the urine outlet hole 402, the front and rear sides of the top plate 401 are not in contact with the inner walls of the urine storage bag 2 and a gap channel is formed therebetween, the bottom end of the top rod 403 abuts against the top surface of the top plate 401, when it is necessary to dismount the urine storage bag 2, the urine storage bag 2 is rotated to disengage the threaded connection between the bag opening and the urinary catheter 1, when the urine storage bag 2 is disengaged from the urinary catheter 1, the top plate 401 no longer abuts against the top rod 403, a sealing block 404 is fixed at the top end of the top rod 403, a limiting plate 405 is fixed at the top end of the sealing block 404, the bottom surface of the limiting plate 405 is fixed with a spring 406 having one end fixed to the inner wall of the urinary catheter 1, the spring 406 is sleeved on the outer peripheral wall of the sealing block 404, further, the top rod 403 loses the support of the top plate 401, the spring 406 is contracted to drive the limiting plate 405, the sealing block 404 and the top rod 403 to move downward, so that the sealing block 404 blocks the urine outlet hole 402, thereby avoiding the dripping of urine from the bottom end of the urinary catheter 1 when the urine storage bag 2 is dismounted, after the cleaning of the urine storage bag 2, the urine storage bag 2 is threadedly connected to the bottom end of the urinary catheter 1, so that the top plate 401 lifts up the top rod 403, thereby stretching the spring 406 and moving the sealing block 404 upward to disengage the urine outlet hole 402.

[0027] The sealing block 404 is a circular block with a tapered bottom end, the diameter of the top rod 403 is smaller than that of the urine outlet hole 402, and the diameter of the sealing block 404 is larger than that of the urine outlet hole 402, so that the sealing block 404 is facilitated to move upward and downward to block the urine outlet hole 402 to achieve the effect of sealing and preventing leakage.
