ABSTRACT:
A closed system suction catheter assembly has a valve which controls suction applied at the patient end of the assembly. The valve has a barrel with a bore through it which is rotatable in a housing between an open position, in which the bore is aligned the inlet and outlet of the valve and a closed position, in which it is out of alignment. The barrel has teeth on its outer surface forming a pinion which are engaged by teeth on the underside of a slidable switch. Sliding of the switch rotates the barrel and controls flow through the valve.
