Abstract
Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves having a pliant valve housing interacting with an inlet connector assembly. The pliant valve housing has an integrally formed valve stem and one or more ports. The valve stem cooperates with a nozzle on the inlet connector assembly to form a slip port, which can open when exerted by force to permit flow or closes when the force is removed.
Claims40
A needleless injection port valve comprising an inlet connector assembly comprising a nozzle comprising an inlet lumen;
- a valve housing comprising at least one port and an integrally molded valve stem positioned at an angle to the at least one port;
- the valve stem comprising a hollow interior cavity in constant fluid communication with ambient air;
- wherein the inlet connector assembly is secured to the valve housing and the valve stem projects, at least in part, through the inlet lumen of the inlet connector assembly.
The needleless injection port valve of claim. 1, wherein the inlet connector assembly is welded to the valve housing.
A needleless injection port valve comprising an inlet connector assembly comprising a nozzle comprising an inlet lumen;
- a valve housing comprising at least one port and an integrally molded valve stem positioned at an angle to the at least one port;
- the valve stem comprising a hollow interior cavity and at least one rib positioned in the hollow interior cavity for reinforcing a section of the valve stem;
- wherein the valve stem projects, at least in part, through the inlet lumen of the inlet connector assembly and the inlet connector assembly is secured to the valve housing along a sealing seam.
A method for supplying fluid through a needleless injection port valve comprising:
- (1) providing a valve, the valve comprising:
- (a) an inlet connector assembly comprising a nozzle comprising an inlet lumen;
- (b) a valve housing comprising at least one port and an integrally molded valve stem positioned at an angle to the at least one port;
- the valve stem comprising a hollow interior cavity and a rib positioned in the hollow interior cavity for reinforcing a section of the valve stem;
- (c) the valve stem projects, at least in part, through the inlet lumen of the inlet connector assembly and the inlet connector assembly is secured to the valve housing along a sealing seam;
- (2) inserting a male end of a medical implement through the inlet lumen of the inlet connector assembly;
- and
- (3) injecting fluid from the medical implement through the inlet lumen.
