Abstract: The invention relates to a catheter valve for permanently or discontinuously draining body cavities and discharging urine. The catheter valve consists of a two-component housing having a cylindrical portion and a conical portion. The conical portion houses a shaft that slides along the longitudinal axis of the housing. At a tip of the conical portion is a urine inlet opening that allows urine or other bodily fluids to flow into the catheter. At an opposite end, is a urine outlet opening that allows the fluid to flow out of the catheter. The shaft controls the flow of fluid through the catheter by selectively sealing the urine outlet opening on the catheter. In addition, a locking mechanism is provided to keep the shaft apart from the outlet valve thus allowing free flow of fluid through the catheter.
