Needleless access port valves
First Claim
1. A needleless access port valve assembly comprising a plunger assembly comprising a band adapted to flex when urged by a medical implement;
- the band, which comprises a length and a cross-sectional circumference of smaller dimension than the length, is compressed along two opposed surfaces between an inlet connector assembly comprising a port and a valve body comprising a port;
said band integrally formed with a plunger and comprising an arcuate shaped structure extending from the plunger, the band being compressed between a seat on the valve body and a seat on the inlet connector assembly.

Abstract
Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves having a stretchable or flexible band. In accordance with aspects of the present invention, the band is held in between a flange section of an inlet connector assembly and a shoulder section of the valve body. A plunger integrally formed with the band is movable inside a nozzle to control fluid flow through the inlet of the valve. When the plunger is urged by a medical implement to open the valve inlet, the band flexes to accommodate the moving plunger.

9. A needleless access port valve assembly comprising a plunger assembly comprising an axially extending plunger and an integrally formed band disposed in between an inlet connector assembly comprising an inlet port and a valve body comprising an outlet port;
- said inlet connector assembly and said valve body defining a groove and at least a portion of said band is disposed in said groove and being compressed thereby;
wherein said band comprises a first length when said plunger is in a first position and a second length, which is longer than the first length, when said plunger is in a second position. - View Dependent Claims (10, 11, 12, 13, 14, 15)
- said inlet connector assembly and said valve body defining a groove and at least a portion of said band is disposed in said groove and being compressed thereby;

16. A needleless access port valve assembly comprising an inlet connector assembly comprising an inlet port, a plunger assembly means, and a valve body comprising an outlet port, said plunger assembly means comprising an integrally formed plunger and spring means compressed in between a groove defined by a flange on the inlet connector assembly and a shoulder on the valve body;
- wherein the spring means flexes in response to a force applied on the plunger and is less flexed when said force is removed from said plunger.
