The right end of the drainage tube 2 is connected with a plug 10 which can be inserted into the drainage tube 2 through a pull rope 9, the plug 10 is of a conical structure with a small left end and a large right end, and the plug 10 is provided with an annular groove 11 corresponding to the groove 4.
In order to achieve better urine collection effect, the urine collection bag is provided with a cannula which has the same shape and structure as the plug 10.
For better sealing, an annular sealing gasket may be provided between the drainage tube 2 and the plug 10.
In order to prevent urine in the urine collection bag from being squeezed and flowing back into the urinary catheter 1, a one-way valve 12 with an opening facing the drainage tube 2 is arranged in the urinary catheter 1.
The left end of the catheter 1 is provided with a plurality of urine inlet holes 13, and the catheter 1 is provided with a saccule 14 positioned on the right side of the urine inlet holes 13.
In order to enable the sleeve 6 to smoothly slide on the drainage tube 2, a plurality of T-shaped chutes in the left and right directions are formed in the outer edge surface of the drainage tube 2, the T-shaped chutes are uniformly distributed along the circumferential direction of the drainage tube 2, and a plurality of T-shaped blocks which can be in one-to-one correspondence with the T-shaped chutes are arranged on the inner side of the sleeve 6.
When the utility model is used, one end of the catheter 1 provided with the urine inlet hole 13 is inserted into the bladder through the urethra, the saccule 14 expands in the bladder, and the end of the catheter 1 provided with the urine inlet hole 13 is fixed in the bladder, so that the catheter 1 can be prevented from moving repeatedly in the urethra when a patient moves or turns over, and the urethral wall and the bladder wall are damaged;
