Description

A leak-proof urinary catheter

Technical Field

The present application relates to the technical field of urinary catheters, and in particular to a leak-proof urinary catheter.

Background Art

In medicine, a catheter is inserted through the urethra into the bladder to drain urine. Catheterization is divided into two types: indwelling catheterization and intermittent catheterization. In the former, the catheter is always in the patient's body and should be removed as soon as the condition permits. The tube must be replaced regularly. In the latter, catheterization is performed every 46 hours and the catheter is removed after the bladder is emptied. Some patients who are unable to urinate independently need to wear a catheter for a long time.

The existing patent (publication number: CN219681273U) discloses a leak-proof urinary catheter for nursing, including a recycler, the bottom end of which is plugged into the top of the urine bag, and the top of the recycler is plugged with a connector. The utility model provides a leak-proof urinary catheter with a recycler and a connector. When in use, the urethra is inserted into the urethra, so that the blocking ball stays at the urethral opening, and the collector is attached near the urethral opening. During normal catheterization, the blocking ball blocks the urethral opening to prevent urine from flowing out of the outer wall of the urethral catheter, while the outflow of urine caused by long-term use is collected by the downward guidance of the downstream sheet and the anti-backflow function, which effectively solves the problem that during the use of the existing urinary catheter, due to the softness of human tissue, urine is easily discharged from between the urethra and the urethral opening, causing urine leakage and affecting the urine collection effect.

The above-mentioned comparative document points out that the device effectively solves the problem that during the use of the existing urinary catheter, due to the softness of human tissue, urine is easily leaked from the urethra and the urinary catheter port, causing urine leakage and affecting the urine collection effect. However, the device can only be fixed in the patient's body. When the patient turns over or moves, urine is easily leaked. The leaked urine is collected in the collector. If the urine stops flowing in the collector for a long time, bacteria are easily generated.
