Abstract

Injection port valves are generally discussed herein and more particularly to port valves that have a valve housing with a nozzle having an inlet opening, a body section, a skirt section, an interior cavity, and a valve seat at an intersection of the first nozzle and the body section in the interior cavity. A piston may be positioned within the interior cavity of the valve housing having a body section having an exterior surface, an upper piston section, a seal surface, and a piston cavity, and wherein the body section includes a wall layer that emits lubricant from within the wall layer to the exterior surface. A nut, which may be a Luer nut, having a flow passage in communication with a discharge nozzle having a discharge lumen may be attached to an end of the skirt section of the valve housing to thereafter connect to an infusion line. A spring can be positioned within the piston cavity and abutting against the nut, wherein when used, the spring being in a first position when the seal surface of the piston is abutted against the valve seat of the valve housing, and the spring being in a second position when the seal surface of the piston is separated from the valve seat.
