Description

Special catheter for female urethral relaxant

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a special catheter for female urethral relaxers.

Background

The catheter body is a pipeline made of natural rubber, silicon rubber or polyvinyl chloride, can be inserted into the bladder through the urethra so as to drain urine, and after the catheter body is inserted into the bladder, a fixing air bag is arranged at the front end of the catheter body to fix the catheter body and enable the catheter body to be remained in the bladder, so that the urine in the bladder is discharged. Women suffer from pelvic floor muscle damage due to birth, and the urethra is mostly loose after the elderly. When a female patient uses the disposable urinary catheter, particularly a patient with a loose urethra, urine in the bladder easily enters the urethral orifice from the loose urethra, the phenomenon of urine leakage occurs, the risk of urinary system infection is increased, and the patient feels uncomfortable.
