Injection port valve
First Claim
1. An injection port valve comprising:
- a valve housing comprising a first nozzle having an inlet opening, a body section, a skirt section, an interior cavity, and a valve seat located in the interior cavity;
a piston positioned within the interior cavity of the valve housing, the piston comprising a body section having an exterior surface, a seal surface, and a piston cavity, wherein the body section comprises a wall layer that emits liquid silicone from within the wall layer to the exterior surface, and wherein the seal surface is abutted against the valve seat of the valve housing;
a nut comprising a flow passage in communication with a discharge nozzle comprising a discharge lumen attached to an end of the skirt section of the valve housing; and
wherein the inlet opening of the first nozzle is in fluid communication with the discharge lumen of the discharge nozzle when the seal surface is spaced apart from the valve seat.

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.

13. An injection port valve comprising:
-
a piston positioned inside a valve housing, the piston comprises a wall having a wall surface that emits medical lubricant from within the wall to the wall surface when the piston is compressed;
a Luer nut attached to an opening of the valve housing, the Luer nut comprising a flow passage and a discharge nozzle defining a port; and
wherein the valve housing further comprises a first nozzle defining an inlet opening, and wherein the inlet opening, the flow passage, and the port of the discharge nozzle are in fluid communication when a syringe tip is inserted into the inlet opening. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
