Abstract

Disclosed herein is a valve assembly comprising a male luer end portion and a female luer end portion and a passage for the transfer of fluids extending between the male and female luer end portions, valve means movable between a first position, in which the passage is closed, and a second position, in which the passage is open, biasing means for biasing the valve means toward the first position, and actuating means extending into the male luer end portion and coupled to the valve means to actuate the valve means when a female luer end portion of a medical accessory is engaged with the male luer end portion.

First claim

The following is claimed:

1. A method of providing a medical connector, the method comprising:
providing a housing including a proximal portion and a distal portion;
providing a female luer;
providing a male luer projection being located at the distal portion of the housing; and
providing a valve member being longitudinally movable between a closed position and an open position, the valve member comprising:
an internal fluid pathway,
a proximal end being moveable between the open position and the closed position, the moveable proximal end comprising an open-ended proximal end surface,
at least one distal opening, and
a distal end portion being located in a distal direction from the at least one distal opening, the distal end portion being configured to obstruct fluid communication between the male luer projection and the internal fluid pathway when in the closed position,
wherein the valve member when in the closed position is configured to inhibit fluid flow through the internal fluid pathway, wherein the valve member when in the open position is configured to allow fluid flow through the internal fluid pathway,
wherein at least a portion of the valve member is positioned within the male luer projection in the closed position,
wherein at least a portion of the valve member is positioned outside of the male luer projection in both the open position and the closed position, and

wherein the valve member is biased toward the closed position.

2. The method of claim 1 , wherein the open-ended proximal end surface is wider than a distal-most end tip of the valve member.

3. The method of claim 1 , wherein the valve member is formed of a single piece of material.

4. The method of claim 3 , wherein the at least one distal opening of the valve member comprises two distal openings.

5. The method of claim 1 , wherein the distal end portion of the valve member comprises a plug.

6. The method of claim 1 further comprising providing an actuating member being configured to actuate at least a portion of the valve member from the closed position to the open position.

7. The method of claim 1 , wherein the valve member extends along the housing from:
(i) a first region of the medical connector that is configured to receive an end of a medical article, to
(ii) a second region of the medical connector containing the male luer projection.

8. The medical connector of claim 1 further comprising providing a biasing member being configured to assert a restoring force on the valve member, the restoring force being configured to move the valve member longitudinally within the housing to the closed position, wherein the biasing member contacts a proximal half of the valve member.

9. A method of providing a medical connector configured to receive a male end of a medical article, the method comprising:
providing a housing comprising a proximal region and a distal region being separate from the proximal region, the proximal region being joined with the distal region;
providing a female luer end being configured to receive a male end of a medical article;
providing a male luer projection;
providing a threaded shroud surrounding at least a portion of the male luer projection, the threaded shroud comprising one or more threads;
providing a valve member being longitudinally movable between a closed position and an open position, the valve member comprising:
an internal fluid pathway,
at least one opening being moveable with the valve member and comprising a distal end being located distal from a proximal end of the one or more threads of the threaded shroud in the open position, and
a distal end portion being located in a distal direction from the at least one opening, the distal end portion being configured to inhibit fluid communication between the male luer projection and the internal fluid pathway when in the closed position, the distal end portion comprising a distal-most end tip being positioned within the male luer projection in both the open position and the closed position, wherein a proximal-most end of the valve member is wider than the distal-most end tip,
wherein the valve member when in the closed position is configured to inhibit fluid flow between the internal fluid pathway and the male luer projection, wherein the valve member when in the open position is configured to allow fluid flow between the internal fluid pathway and the male luer projection through the at least one opening, and
wherein the valve member is biased toward the closed position; and

positioning the valve member within the housing such that at least a portion of the valve member is located outside of the male luer projection when the valve member is in both the open position and the closed position.

10. The method of claim 9 , wherein at least a portion of the valve member is positioned within the male luer projection in the closed position.

11. The method of claim 9 , wherein the proximal-most end of the valve member comprises a proximal-facing opening.

12. The method of claim 9 , wherein the at least one opening of the valve member further comprises two distal openings.

13. The method of claim 9 , wherein the valve member is formed of a single piece of material.

14. The method of claim 13 , wherein the valve member extends along the housing from:
(i) a first region of the medical connector that is configured to receive the male end of the medical article, to
(ii) a second region of the medical connector containing the male luer projection.

15. The method of claim 9 , wherein the distal-most end tip of the valve member comprises a plug.

16. The method of claim 9 further comprising providing an actuating member being configured to actuate at least a portion of the valve member from the closed position to the open position.

17. The medical connector of claim 9 further comprising providing a biasing member being configured to assert a restoring force on the valve member, the restoring force being configured to move the valve member longitudinally within the housing to the closed position, wherein the biasing member contacts a proximal half of the valve member.

18. The method of claim 9 further comprising providing the medical article.
