Abstract

Needleless access port valves are generally discussed herein with particular discussions extended to needleless access port valves comprising an inlet coupler. In accordance with aspects of the present invention, a coupler comprises an inlet and an outlet. The inlet is adapted to mate with a first medical implement and the outlet is adapted to mate with an inlet of a valve, which has an outlet adapted to mate with a second medical implement.

Claims

1. A needleless access port valve assembly comprising a coupler comprising an inlet and an outlet and a valve comprising an inlet and an outlet;

wherein the outlet of the coupler comprises a port comprising a curved section and the inlet of the valve comprises a septum and wherein the septum is configured to receive the port and the curved section of the port is configured to rotate relative to the septum.

2. The needleless access port valve of claim 1, wherein the inlet of the coupler comprises a threaded luer.

3. The needleless access port valve of claim 1, wherein the coupler comprises a pair of fins.

4. The needleless access port valve of claim 1, wherein the valve comprises a two-part housing.

5. The needleless access port valve of claim 4, wherein the two-part housing is welded along a seam.

6. The needleless access port valve of claim 4, wherein the septum is disposed between an upper housing part and a lower housing part of the two-part housing.

7. The needleless access port valve of claim 6, wherein the outlet comprises a male threaded luer.

8. The needleless access port valve of claim 1, wherein the coupler comprises a housing over-molded to the curved section.

9. The needleless access port valve of claim 1, wherein the septum comprises a seam.

10. The needleless access port valve of claim 1, further comprising at least one indentation on a top surface of the valve.

11. A needleless access port valve assembly comprising a coupler matingly engaged to a valve;

the coupler comprising an inlet for mating with a first medical implement and the valve comprising an outlet for mating with a second medical implement, wherein the engagement between the coupler and the valve comprises a port comprising a flow section having a fluid opening projecting through a septum and rotating the flow section relative to the septum.

12. The needleless access port valve of claim 11, wherein the inlet of the coupler comprises a threaded luer.

13. The needleless access port valve of claim 11, wherein the coupler comprises a pair of fins.

14. The needleless access port valve of claim 11, wherein the flow section comprises a curved section.

15. The needleless access port valve of claim 11, wherein the coupler comprises a housing and the flow section comprises a linear section extending distally from the housing.

16. The needleless access port valve of claim 11, wherein the valve comprises a two-part housing.

17. The needleless access port valve of claim 16, wherein the septum is disposed in between an upper housing part and a lower housing part of the two-part housing.

18. The needleless access port valve of claim 17, wherein the two-part housing is welded along a seam.

19. The needleless access port valve of claim 11, wherein the outlet comprises a male threaded luer.

20. The needleless access port valve of claim 11, wherein the septum comprises a slit.

21. The needleless access port valve of claim 11, further comprising at least one indentation on a top surface of the valve.

22. A needleless access port valve assembly comprising a coupler matingly engaged to a valve, the coupler comprising an output means for outputting fluid flow and for engaging the valve;

the valve comprising a connection means for receiving the output means, wherein the output means is rotatable relative to the connection means; and

wherein the coupler further comprising an inlet for engaging a first medical implement and the valve comprising an outlet for engaging a second medical implement.

23. The needleless access port valve assembly of claim 22, wherein the output means comprises a port comprising a flow section.

24. The needleless access port valve assembly of claim 22, wherein the connection means comprises a septum comprising a slit.

25. The needleless access port valve assembly of claim 23, wherein the port comprises an L shape configuration.

26. The needleless access port valve assembly of claim 23, wherein the port comprises an upside-down T shape configuration.

27. The needleless access port valve assembly of claim 22, wherein the valve comprises a two-part housing.

28. The needleless access port valve assembly of claim 22, wherein the coupler comprises a threaded inlet luer.

29. The needleless access port valve assembly of claim 22, wherein the valve comprises a threaded outlet luer.

30. The needleless access port valve assembly of claim 27, wherein the connection means is disposed in between an upper housing part and a lower housing part of the two-part housing.
