Description

Technical Field

[0001] The present invention relates to the technical field of medical devices for preventing urinary tract infection, in particular to a urinary catheterization device capable of preventing urinary tract infection. Background Art

[0002] Catheterization is a common medical procedure performed clinically. It involves inserting a catheter through the urethra into the bladder to drain urine. There are two types of catheterization: indwelling catheterization and intermittent catheterization. In the former, the catheter remains permanently in place and is removed as soon as the patient's condition permits, requiring regular replacement. In the latter, the catheter is catheterized every 4-6 hours and removed once the bladder is empty. Regardless of the catheterization method, considerations should be taken to prevent urinary tract infections and increase the catheterization rate.

[0003] Patent publication number CN221490885U provides a urinary catheterization device that can prevent urinary tract infections. The device includes a buffer chamber and a urinary catheterization component. The urinary catheterization component includes an air bag and an antibacterial sleeve. The urinary catheterization component discharges urine. The device avoids secondary damage to the patient due to urinary tract infection through the antibacterial sleeve. By setting up a buffer chamber, the pressure on the bladder caused by the patient's direct urination is buffered, thereby reducing the pressure on the patient's urethra. However, the device does not consider how to speed up the catheterization rate, and the catheterization rate is too slow.

[0004] To this end, the present invention provides a urinary catheterization device capable of preventing urinary tract infection, which accelerates the catheterization rate while preventing urinary tract infection. Summary of the Invention
