Embodiment 1
[0027] See figure 1 , figure 1 It is a structural schematic diagram of a safety leak-proof urinary catheter disclosed by the present invention. The safety leak-proof urinary catheter includes a catheter body 1, a catheterization cavity 2, and a leak-proof air bag 3 sleeved at the front end of the catheter body 1. The catheter body 1 is also provided with a urine inlet hole 4 connected with the catheterization cavity 2, and the urine inlet hole 4 is located at the front end of the leak-proof air bag 3; the leak-proof air bag is mainly used to seal the urine in the bladder to ensure that the urine can be effectively The urine enters the catheterization chamber 2 through the urination hole 4 to avoid leakage of urine. The urine inlet hole is arranged at a position close to the leak-proof air bag, so that the urine in the bladder can directly and effectively enter the catheterization cavity.
[0028] The urine inlet hole at the front end of the leak-proof air bag 3 can be 1 or 2...
Embodiment 2
[0037] See figure 2 , as shown in the figure, the rest are the same as in Embodiment 1, the difference is that the urinary catheter body 1 is also sleeved with auxiliary airbags 5, and the auxiliary airbags 5 are arranged on the urinary catheter body 1 in turn to prevent leakage. 2. A urine inlet hole 4 corresponding to the auxiliary air bag 5 is also provided on the urinary catheter body 1 close to the front end of the auxiliary air bag 5 . A corresponding airbag chamber 6 is connected to the auxiliary airbag 5 , and an inlet 7 is provided at one end of the airbag chamber 6 . The auxiliary bladder is pumped or injected with gas / liquid through the inlet 7 .
[0038] The front end of each auxiliary airbag 5 is correspondingly provided with one or two symmetrically arranged or evenly distributed multiple urine inlet holes, so as to ensure that the leakage of urine flowing out through the internal opening of the urethra flows into the catheter through the urine inlet holes her...
