Patent Images
1. A needleless injection port valve assembly comprising a valve housing comprising an inlet port, an outlet port, and a valve base;
- the inlet port defining an opening and an interior cavity comprising a plurality of ribs;
a plug disposed in the interior cavity of the inlet port and having a first position and a second position;
the first position is characterized by the plug spaced apart from the valve base and the second position is a valve open position characterized by the plug abutting the valve base and deflecting the valve base outwardly away from the opening.

Abstract
Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves comprising a stretched body. In one aspect of the present invention, a plug is positioned inside a slip port. When the plug is pushed by a medical implement and moves to a second position, the plug abuts the valve body and stretches the valve body. When the medical implement is subsequently removed, the stretched body forces the plug back to its first position.
