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.

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 characterized by the plug abutting the valve base and urging the valve base outwardly away from the opening.
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 an upper cavity section and a lower cavity section;
- a plug disposed in the interior cavity of the inlet port and a plug lower section spaced apart from a deflection shoulder positioned on the valve base;
- and wherein the valve base is urged outwardly away from the opening when the plug moves from a first position to a second position and abuts the deflection shoulder.
A needleless injection port valve assembly comprising a valve housing comprising an inlet port and an outlet port;
- the inlet port defining an opening and an interior cavity comprising an upper cavity section and a lower cavity section;
- a plug disposed in the interior cavity of the inlet port;
- stretch means for both stretching to accommodate the plug and for pushing the plug into contact with the upper and lower cavity sections.
