Abstract

Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves comprising a resilient valve body. The resilient valve body includes a tapered set port that stretches when a plug is pushed by a medical implement which in turn pushes the set port. Pushing the plug against the set port opens fluid communication between the inlet port and the outlet port. Upon removal of the medical implement, the resilient valve body pushes the plug back to its closed position.

Claims

1. A needleless access port valve comprising a valve body, an inlet port, an outlet port, a set port comprising a squeezed end comprising a sealed seam, and a plug moveable from between the inlet port and the set port for allowing fluid communication between the inlet port and the outlet port.

2. The needleless access port valve of claim 1, wherein the set port further comprises a vent hole.

3. The needleless access port valve of claim 1, wherein the set port tapers outwardly as it extends towards the inlet port.

4. The needleless access port valve of claim 1, wherein the valve is made from a thermoplastic elastomer.

5. The needleless access port valve of claim 1, further comprising a threaded collar engaged to the outlet port.

6. The needleless access port valve of claim 5, wherein the threaded collar is made from a rigid plastic material.

7. The needleless access port valve of claim 1, wherein the outlet port comprises a groove along an exterior surface for engaging an opening of a collar.

8. The needleless access port valve of claim 7, where the collar comprises a plurality of protrusions.

9. The needleless access port valve of claim 1, wherein the plug comprises a dome-shape section and a base section.

10. A needleless access port valve comprising a valve body, an inlet port, an outlet port, a set port comprising a seam and a taper surface that tapers radially outwardly as it extends towards the inlet port, and a plug comprising a dome, a first position, and a second position;

wherein the dome abuts the taper surface when the plug is in the second position.

11. The needleless access port valve of claim 10, wherein the seam is heat welded.

12. The needleless access port valve of claim 10, wherein the seam is laser welded.

13. The needleless access port valve of claim 10, wherein the seam comprises a vent hole.

14. The needleless access port valve of claim 10, wherein the valve is made from a thermoplastic elastomer material.

15. The needleless access port valve of claim 10, further comprising a collar connected to an exterior surface of the outlet port.

16. The needleless access port valve of claim 15, wherein the collar engages the exterior surface in a tongue-and-groove arrangement.

17. The needleless access port valve of claim 16, wherein the collar comprises a plurality of threads.

18. The needleless access port valve of claim 10, wherein the outlet port comprises a male luer taper.

19. The needleless access port valve of claim 10, wherein the inlet comprises exterior threads.

20. A needleless access port valve comprising a valve body, an inlet port, an outlet port, a set port comprising a vent hole and a seam formed by a squeezed end, a collar matingly engaged to the outlet port, and a plug operatively moveable by a medical implement to permit fluid communication between the inlet port and the outlet port.

21. The needleless access port valve of claim 20, wherein the collar is engaged to the outlet port in a tongue-and-groove arrangement.

22. The needleless access port valve of claim 20, wherein the seam is sealed by heat welding.

23. The needleless access port valve of claim 20, wherein the seam is sealed by bonding.

24. The needleless access port valve of claim 20, wherein the inlet port comprises exterior threads.

25. The needleless access port valve of claim 20, wherein the valve is made from a thermoplastic elastomer material.
