2. The utility model discloses in, the end is thick both ends thin structure in the middle of, and inside the tip was thinner can make things convenient for medical personnel to stretch into the bladder with the end, the up end of end is the cambered surface, sets up the inner wall that the tip fish tail bladder that the cambered surface can avoid the end.

3. The utility model discloses in, the inlet all distributes in the first half of end, ensures that the urine that gets into the cavity can not leak from the lower part of end.

4. The utility model discloses in, the upper surface of sacculus runs through and is equipped with the opening, and the upper end of ureter is worn out from the opening to, be equipped with in the opening with the sealing washer of ureter laminating, set up in the sealing washer can prevent that the urine from entering into the sacculus, also can avoid the rivers in the sacculus to go out to the bladder simultaneously.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Example (b): an anti-blocking catheter is shown in figure 1, and comprises a urinary catheter 1, a sleeve 2 is arranged outside the urinary catheter 1, a water inlet pipe 3 is arranged on the side portion of the sleeve 2, a tube plug 4 is arranged on the water inlet pipe 3, the lower end of the sleeve 2 is in a closed shape, the lower end of the sleeve 2 is integrated on the side wall of the urinary catheter 1, a balloon 6 is arranged at the upper end of the sleeve 2 in a communication manner, the urinary catheter 1 penetrates through the middle of the balloon 6, the balloon 6 is wrapped on the upper portion of the urinary catheter 1, when in use, the deflated balloon 6 and the upper end of the urinary catheter 1 extend into a bladder together, then water is injected into the sleeve 2 through the water inlet pipe 3, the water enters the balloon 6 to inflate the balloon 6, and the outer wall of the balloon 6 is tightly attached to the bladder wall 5, so as to prevent urine from leaking from the outside of the urinary catheter 1 and avoid urine leakage, an opening 10 is arranged on the upper surface of the balloon 6, the upper end of the urinary catheter 1 penetrates out of the opening 10, a sealing ring 11 attached to the urinary catheter 1 is arranged in the opening 10, the sealing ring 11 can prevent urine from entering the balloon 6, meanwhile, water in the balloon 6 can be prevented from flowing into the bladder, as shown in figure 2, the upper end of the urinary catheter 1 is provided with an end head 7, the end head 7 is made of rubber, the end head 7 is of a structure with a thick middle part and thin two ends, the thin end part can facilitate medical staff to stretch the end head 7 into the bladder, the upper end surface of the end head 7 is an arc surface 701, the arc surface 701 is arranged to prevent the end part of the end head 7 from scratching the inner wall of the bladder, a cavity 8 communicated with the urine drainage tube 1 is arranged in the end head 7, a plurality of liquid inlets 9 communicated with the cavity 8 are arranged on the upper surface of the end head 7, as shown in figure 3, the loading ports 9 are all located in the upper half of the tip 7 to ensure that urine entering the cavity 8 does not leak from the lower part of the tip 7.
