technical field

The utility model belongs to the technical field of medical instruments, in particular to a medical catheter provided with a liquid-stopping clamp.

Background technique

Commonly used catheters currently on the market include disposable single-lumen, double-lumen, and triple-lumen catheters. Those with indwelling catheters often choose double-lumen or triple-lumen catheters. In the process of catheterization, in order to prevent urinary tract infection, it is often necessary to perform bladder irrigation twice a day or continuous bladder irrigation. Conventional bladder irrigation is usually performed after the drainage tube is folded back, and an infusion needle is used to puncture the urinary catheter and drainage bag. at the connecting section. In the process of bladder irrigation, if the angle and strength of the needle are not properly grasped, it may penetrate the urinary catheter, resulting in needle contamination and medical safety incidents. The urinary catheter leaks urine, and if the condition requires it, the catheter needs to be re-placed, which increases the suffering of the patient. In addition, before extubation, in order to exercise the contractile function of the bladder sphincter, the drainage tube needs to be clamped regularly to hold back urine. The existing urinary catheter can meet the clinical needs, but there are still some deficiencies.

Using the existing urinary catheter, it is impossible to quickly clamp the urinary catheter, which will easily cause waste of medical supplies during use, increase the economic burden and physical pain of the patient, or cause occupational safety incidents of medical staff, and increase the contradiction between doctors and patients. It can be seen that whether a new type of urinary catheter can be invented to realize rapid clamping of the urinary catheter, and it is easy to operate when performing bladder irrigation, and the effect of reducing the patient's economic burden and physical pain has become a technical problem to be solved urgently by those skilled in the art.
