Abstract

A luer connector including a housing with first end including a male luer tip and a second end. The connector further includes a rigid valve member having a first opened end and a second closed end and a resilient member configured to couple the valve member and the housing. The housing further includes a rigid conduit positioned within the housing and in fluid communication with the second end of the housing, the rigid conduit adapted to engage the first opened end of the valve member. The housing defines a first internal volume when the valve member is in a first position and a second, smaller volume when the valve member is in a second position.

First claim

What is claimed is:

1. A medical connector comprising:
a housing with a central axis and a hollow bore having a male end with a male luer tip and a female end, wherein the bore includes a narrowed passage connecting an interior region of the housing with the female end, said narrowed passage having a cross sectional area that is smaller than the cross-sectional area of the interior region of the housing adjacent the narrowed passage and the female end adjacent the narrowed passage;
a rigid valve member configured to at least partially extend into an interior space of the male luer tip, the valve member comprising a first end, a second closed end, an internal passageway, at least one opening near the closed end of the valve member extending through the valve member and into the passageway;
a fluid chamber extending from the first end of the valve member, said fluid chamber including a closed end and a first hole near said closed end, wherein said fluid chamber extends into said narrowed passage and is configured such that said first hole engages said narrowed passage when the valve member is in a first position and said first hole does not engage the narrowed passage when the valve member is in a second position;
a resilient member configured to couple the valve member and the housing; and
a sealing portion disposed within the housing and configured to inhibit fluid communication through the hollow bore of the housing between the interior of the male luer tip of the housing and the exterior of the valve member.

2. The medical connector of claim 1 , wherein the interior region of the housing adjacent the narrowed passage is partially defined by a rigid conduit in fluid communication with the female end, the rigid conduit and the first end of the valve member being moveable relative to each other along the central axis such that at least a portion of the valve member and the rigid conduit overlap, thereby producing a change in volume in the interior region as the valve member moves from the first position to the second position, the volume of the interior region being larger in the first position than in the second position.

3. The medical connector of claim 1 , wherein a portion of the biasing member is positioned on an exterior surface of the housing.

4. The medical connector of claim 1 , wherein the fluid chamber is coupled to the valve member.

5. The medical connector of claim 4 , wherein the fluid chamber includes a second hole positioned between the first hole and the valve member to fluidly couple the interior of the fluid chamber with the interior region of the housing.
