Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of catheter, especially to antibacterial catheter. BACKGROUND

[0002] A catheter is a medical device used to direct the flow of urine from the bladder. It is usually made of soft silicone, latex, or plastic. The catheter is inserted through the urethra into the bladder to help patients who cannot urinate on their own to expel urine. It is widely used for patients after surgery, patients with urinary system diseases, patients in coma or long-term bedridden, and other patients who need short-term or long-term help to urinate. Traditional catheters are prone to bacterial infection along the surface of the catheter when left in place for a long time, leading to urinary tract infection in the bladder, kidneys, and other parts. Therefore, antibacterial catheters are needed.

[0003] Catheters can be divided into several types, including silicone catheters, polyurethane catheters, and latex catheters. Different types of catheters are suitable for different clinical needs and patient conditions. Doctors will choose the appropriate catheter based on the patient's specific condition. In the use of silicone catheters, urine is drained from the bladder to an external container. One end of the catheter is inserted into the bladder, and the other end is connected to a urine bag or other collection device. The internal channel of the catheter allows urine to flow smoothly, while its smooth surface and good biocompatibility reduce irritation to the urethra and bladder.
