Abstract
An arrangement for irrigating a patient's bladder following prostate or bladder surgery which includes a valve body having five circumferentially spaced ports thereon and a valve core rotatable within the valve body and having passageways therein for interconnecting selective ports on the valve body when the core is rotated to predetermined positions for admitting irrigating fluid to the bladder through a urinary catheter and for conveniently draining the irrigating fluid from the bladder into a urinary drainage receptacle. The valve is constructed so that the entire irrigating and drainage procedure can be performed either intermittently or continuously without disconnecting the valve ports from the catheters or the irrigating supply and drainage receptacles employed in the arrangement.
