Abstract: A three-way urinary irrigation valve for use with a catheter is disclosed which is movable from a first position in which long term drainage takes place to a second position in which irrigating liquid can be introduced to a bladder, all while maintaining a closed system. The urinary irrigation valve includes a housing defining a first passage having an inlet leading to a bladder and an outlet leading to a drainage bag, and a second passage angularly disposed relative to the first passage and having an inlet at one end and an opposite closed end. A valve gate disposed in the second passage controls the flow of liquids between the inlet and outlet in the first passage, and between the inlet in the first passage and the second passage. An open-topped cap sealingly engages the housing adjacent the end of the second passage having the inlet.
