Abstract:
A valved device adapted for controlling flow into or out from a surgical patient, said valved device comprising:a body defining a flow passageway;a valve connected to said body in flow communication with said flow passageway, said valve comprising a barrel and a piston extending within said barrel;said piston being mounted for selectively displacing said piston longitudinally within said barrel in a direction along the axis of said barrel to selectively permit primary passage flow into or out from said surgical patient; andsaid piston also being mounted for selectively rotating said piston within said barrel in a direction about said axis of said barrel to selectively permit secondary passage flow into or out from said surgical patient;said piston being mounted to occupy a longitudinal position in said barrel wherein said means for rotating is adapted to rotate said piston and to selectively permit said secondary passage flow without further axial displacement of said piston,and a seal positioned to prevent flow out from said barrel through a port when said piston is in a radial position in which flow in said secondary passage is prevented, and said seal is positioned to permit flow out from said barrel and out said secondary passage when said piston is rotated to a radial position in which said secondary flow is permitted, all without further axial displacement of said piston in said barrel.
