Abstract

An IV set includes a drip chamber having a top end and a bottom end. A spikeless connector covers the top end, and an IV tube is connected to the bottom end of the drip chamber. The end of the IV tube opposite the drip chamber is engaged with a needleless/spikeless connector. Thereby, a needleless/spikeless IV set is rendered. A reflux valve including a deformable valve member and reciprocating valve element is also disclosed for use in conjunction with the needleless/spikeless IV connectors.

Claims

1. A valve, comprising:

a valve body configured as a Luer fitting;

a resilient valve member defining an outer periphery that is uninterrupted within the periphery disposed in the valve body and biased to a first configuration, wherein a passageway for fluid communication is not established through the valve body, the member being movable to a second configuration, wherein fluid communication through the valve body is permitted; and

a male valve element disposed in the valve body and defining an engagement surface extending outwardly beyond the valve body for contacting a spikeless/needleless connector to cause the valve element to move against the valve member and move the valve member to the second configuration.

2. The valve of claim 1, further comprising a collar connected to the valve body and extending away therefrom.

3. The valve of claim 2, wherein the collar is a tamper-evident collar having ratchet teeth.

4. The valve of claim 1, wherein the valve member is formed with a skirt defining a surface having an opening formed therein.

5. The valve of claim 1, wherein the valve body is configured as a male Luer fitting having a collar.

6. The valve of claim 5, wherein the collar is rotatable relative to the valve member.

7. The valve of claim 1, in combination with a drip chamber.

8. The valve of claim 1, in combination with an IV container.

9. The valve of claim 1, in combination with a stopcock.

10. The valve of claim 1, in combination with a T-fitting.

11. The valve of claim 1, in combination with a Y-fitting.

12. The valve of claim 1, in combination with an adaptor.

13. The valve of claim 1, in combination with a syringe.

14. A syringe having a discharge port and a connector disposed in the discharge port to selectively block the discharge port, the connector being configured as a female Luer fitting having a resilient valve member in a body and biased to a first configuration, wherein a passageway for fluid communication is not established through the connector, the member being movable to a second configuration, wherein fluid communication is permitted.

15. An IV disposable system that reseals when disconnected, comprising:

a distal end configured as a Luer fitting with a resilient valve member defining an outer periphery that is uninterrupted within the periphery, disposed in the distal end and biased to a first a first configuration, wherein a passageway for fluid communication is not established through the system, the member being movable to a second configuration, wherein fluid communication is permitted;

an intermediate structure; and

a proximal end configured as a Luer fitting with a resilient valve member defining an outer periphery that is uninterrupted within the periphery, disposed in the proximal end and biased to a first a first configuration, wherein a passageway for fluid communication is not established through the system, the member being movable to a second configuration, wherein fluid communication is permitted, the intermediate structure interconnecting the distal and proximal ends.

16. The IV disposable system of claim 15, wherein one of the distal and proximal ends is configured as a male Luer fitting and one of the proximal and distal ends is configured as a female Luer fitting.

17. The IV disposable system of claim 15, wherein both the proximal and distal ends are configured as a male Luer fitting.

18. The IV disposable system of claim 15, wherein both the proximal and distal ends are configured as a female Luer fitting.

19. The IV disposable system of claim 15, wherein the intermediate structure is an intravenous infusion set including at least an intravenous infusion line extending between the proximal and distal ends.

20. The IV disposable system of claim 15, wherein the structure is an adaptor.

21. The IV disposable system of claim 15, wherein the structure is a Y-site.

22. The IV disposable system of claim 15, wherein the structure is a T-site.

23. The IV disposable system of claim 15, wherein the structure is a drip chamber.

24. The IV disposable system of claim 15, wherein the structure is a stopcock with at least two ports.

25. The IV disposable system of claim 15, wherein the structure is a filter.
