A female-specific catheter comprises a main body tube having an inner surface (11) and an outer surface (12), and further comprising at least a urethra outside the catheter head tip (131) in use therein The mouth fixing member (7), the flexible urethral guiding member (75), the catheter driving member (8) which is sleeved with the cylindrical body (71) of the external urethral opening fixing member (7), and the catheter urine The special structure such as the hydrophobic flow stop member (6) at the outlet (140), the thin section (16) for expanding the urethral strict region, the pump tube (68), and the tube bed (69) are not only "closed by the guide" The "safe mode" eliminates the drawbacks of the traditional "unguided dangling", completely avoids contamination of the catheter by the tissue around the urethra (013), and also minimizes urethral stricture during implantation. The urethral intima (011) is damaged; avoiding the leakage of urine to the outlet of the catheter; effectively eliminating the blockage of the urine inlet (130) due to blood clots and tissue masses in the bladder during indwelling, and using with a special peristaltic pump The residual urine volume can also be minimized. |
