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 medical connector comprising:
housing comprising:
a male luer end portion with an opening, and
an internal thread on an interior surface of the housing near the opening, the internal thread configured to receive a separate medical connector;

a female luer end portion positioned in a proximal region of the medical connector, the female luer end portion comprising an external thread on an outer surface of the female luer end portion, and the female luer end portion being configured to receive a male luer;
a valve member comprising:
a generally tubular body with a proximal portion and a distal portion;
a valve lumen extending inside the generally tubular body from the distal portion of the generally tubular body to the proximal portion of the generally tubular body; and
a plug at a distal end of the valve lumen;
wherein the generally tubular body has a first position configured to inhibit fluid flow through the generally tubular body to or from the separate medical connector, and the generally tubular body has a second position configured to allow fluid flow through the generally tubular body to or from the separate medical connector,
wherein the generally tubular body is biased to the first position; and

an actuating biasing member positioned between the male luer end portion and the internal thread on the interior surface of the housing, the actuating member and configured to actuate the generally tubular body from the first position to the second position,
wherein the actuating member is coupled to the valve member at a location proximal from the plug.

2. The medical connector of claim 1 , wherein the actuating member actuates the generally tubular body when the separate medical connector engages the housing.

3. The medical connector of claim 1 , wherein the valve member comprises an anchor flange, wherein the actuating member is coupled to the anchor flange.

4. The medical connector of claim 1 , wherein the male luer end portion of the housing extends further in the distal direction than the internal thread on the interior surface of the housing.

5. The medical connector of claim 1 , wherein the valve member is positioned within the housing.

6. The medical connector of claim 5 , wherein the plug on the valve member has an outer surface that is tapered.

7. The medical connector of claim 6 , wherein the valve lumen extends within the valve member from the plug to the female luer end portion.

8. The medical connector of claim 1 , wherein the valve member further comprises lateral side openings adjacent the plug and in fluid communication with the valve lumen.

9. The medical connector of claim 1 , wherein the plug is positioned within the opening of the male luer end portion.

10. The medical connector of claim 1 , wherein the male luer end portion further comprises a central fluid channel and the opening is positioned at an end of the central fluid channel.

11. The medical connector of claim 10 , wherein the central fluid channel is positioned within and extends distally past the internal thread.

12. The medical connector of claim 10 , wherein the central fluid channel comprises a valve seat.

13. The medical connector of claim 12 , wherein the plug is movable relative to the valve seat and configured to engage the valve seat to inhibit fluid flow through the central fluid channel when the generally tubular body is in the first position.

14. The medical connector of claim 1 , wherein the male luer configured to be received by the female luer end portion further comprises a syringe.

15. The medical connector of claim 1 , wherein the valve member is integrally formed with the female luer end portion.

16. The medical connector of claim 1 , wherein the actuating member comprises at least one abutment element configured to engage with the separate medical connector.

17. A fluid communication system comprising the medical connector of claim 1 in combination with the separate medical connector.
