1. In a catheter arrangement for irrigating a patient'"'"'s bladder the combination comprising a valve body having a circular bore and a circular cylindrical core rotatively retained in said bore, said body having first, second, third, fourth and fifth ports spaced successively around the periphery of the body and communicating with said bore, said first port being connected with a source of irrigating fluid, the second port being connected to a syringe, the third port being connected to a drainage fluid container, the fourth port being connected to a first lumen of a urinary catheter adapted to be extended into the patient'"'"'s bladder and the fifth port being connected to a second lumen of said catheter, said core having first and second separate and distinct passageways therein, said first passageway having generally diametrically opposite ends extending to said bore, one of said ends having a dimension circumferentially of said bore much larger than the other end, said second passageway being located at one side of said first passageway, said passageways and ports being dimensioned and arranged circumferentially relative to each other so that in a first rotative position of said core the large end of said first passageway communicates with both the first and second ports, the small end of the first passageway is sealed by said bore and the remaining ports are sealed from said first passageway and from each other by said core so that the syringe can be operated to draw a quantity of irrigating fluid from said source through said large end of said first passageway and into the syringe, said core being rotatable in one direction from said first position to a second position wherein said large end of said first passageway connects with said second port, the smaller end of the first passageway connects with said fourth port and the first, third and fifth ports are sealed from each other and from said first passageway by said core so that the syringe can be operated first to discharge the fluid therein through said first passageway and into the first lumen of the catheter and then to draw the fluid from the bladder back into the syringe through said first lumen, said core being rotatable in said one direction from said second position to a third position wherein said large end of the first passageway communicates with both the second and third ports, the small end of the first passageway is sealed by said bore and the remaining ports are sealed from each other and from said first passageway by said core so that the syringe can be operated to discharge the fluid therein that has been withdrawn from the bladder into said drainage container through said large end of the first passageway, said core being rotatable still further in said one direction from said third position to a last position wherein the large end of the first passageway communicates with both the third and fourth ports and the second passageway interconnects the first and fifth ports and the second port is sealed from said passageways and from the remaining ports by said core to permit irrigating fluid to be directed into the bladder at a controlled rate through the second passageway and the second lumen of the catheter and simultaneously drained from the bladder through the first lumen or, in the alternative, when flow of fluid from the source is arrested, to permit the patient'"'"'s bladder to drain in an ordinary urinary manner through said first lumen into said drainage container.
