Description

Technical Field

[0002] A urinary catheter is a tube made of natural rubber, silicone rubber or polyvinyl chloride, which can be inserted into the bladder through the urethra to drain urine. After the urinary catheter is inserted into the bladder, there is an airbag near the head end of the urinary catheter to fix the urinary catheter in the bladder and prevent it from slipping out easily, and the drainage tube is connected to a urine bag to collect urine. Urinary catheters are generally divided into ordinary urinary catheters: for one-time non-indwelling catheterization; mushroom-shaped urinary catheters: for suprapubic cystostomy and cecostomy; pointed urinary catheters: for prostatic hyperplasia; metal urinary catheters: for failed ordinary catheterization due to urethral orifice stenosis.
