Abstract

A medical connector includes a housing with a central axis, a hollow bore, and a narrowed passage. The connector further includes a rigid valve member configured to move along the axis of the connector as the connector moves between an open and closed configuration. The connector includes a resilient member coupled to the valve member and the housing.

First claim

The following is claimed:

1. A medical connector configured to receive a male luer end of a medical article, the medical connector comprising:
a housing having a proximal portion and a distal portion;
a female end in the proximal portion of the housing, the female end configured to receive the male luer end of the medical article;
a male end having a male luer, the male luer comprising a first region and a second region, the second region having an internal cross-sectional width that is smaller than an internal cross-sectional width of the first region of the male luer;
a rigid valve member being longitudinally movable along a central axis of the housing between an open position to a closed position, the valve member comprising:
an internal fluid channel,
a closed distal end, and
at least one opening adjacent the closed distal end,
wherein at least a portion of the closed distal end of the valve member is positioned within the second region of the male luer when the valve member is in the closed position;

an elastically deformable resilient member at least partially exposed outside the housing, the resilient member configured to couple the valve member and the housing; and
a sealing element at least partially disposed within the distal portion of the housing at a location proximal from the second region of the male luer, the sealing element configured to inhibit fluid communication through the housing between an interior surface of the male luer and an interior surface of the proximal portion of the housing.

2. The medical connector of claim 1 , wherein the second region of the male luer comprises a sealing surface extending at a non-orthogonal angle relative to the central axis of the housing.

3. The medical connector of claim 1 , wherein the second region of the male luer is formed of a single piece of material with the first region of the male luer.

4. The medical connector of claim 1 , wherein the second region of the male luer is spaced axially along the male luer from the first region of the male luer.

5. The medical connector of claim 1 , wherein the valve member comprises an open-ended proximal end surface.

6. The medical connector of claim 5 , wherein the open-ended proximal end surface has a cross-sectional width larger than the closed distal end.

7. The medical connector of claim 1 , wherein the sealing element comprises a sidewall and at least one protrusion extending radially outwardly form from the side wall.

8. The medical connector of claim 7 , wherein the protrusion is axially secured in both a proximal direction and a distal direction.

9. The medical connector of claim 1 , wherein the elastically-deformable resilient member is in an extended position when the valve member is in the open position.

10. A medical connector configured to receive a male luer end of a medical article, the medical connector comprising:
a housing having a hollow bore, the hollow bore comprising:
a first region comprising a female end configured to receive the male luer end of the medical article,
a second region comprising a male end having a male luer, and
a narrowed passage defined by one or more walls of the housing, the narrowed passage in fluid communication between the first region and the second region, the narrowed passage having a cross-sectional width that is smaller than a cross-sectional width of the first region and the second region;

a rigid valve member being longitudinally movable along a central axis of the housing between an open position to a closed position, the valve member comprising:
an internal fluid channel,
a closed end, and
at least one opening adjacent the closed end,
wherein at least a portion of the closed end of the valve member is positioned within the narrowed passage when the valve member is in the closed position, and
wherein the at least one opening is in fluid communication with the female end when the valve member is in the open position;

a resilient member at least partially exposed outside the housing, the resilient member configured to couple the valve member and the housing; and
a sealing element at least partially disposed within the distal portion of the housing at a location proximal to the second region of the male luer, the sealing element configured to inhibit fluid communication through the housing between an interior surface of the male luer and an interior surface of the proximal portion of the housing.

11. The medical connector of claim 10 , wherein the narrowed passage is formed of a single piece of material with at least one of the first region and the second region.

12. The medical connector of claim 10 , wherein the valve member comprises an open-ended proximal end surface.

13. The medical connector of claim 12 , wherein the open-ended proximal end surface has a cross-sectional width larger than the closed distal end.

14. The medical connector of claim 10 , wherein the sealing element comprises a sidewall and at least one protrusion extending radially outwardly form from the side wall.

15. The medical connector of claim 14 , wherein the protrusion is axially secured in both a proximal direction and a distal direction.

16. The medical connector of claim 10 , wherein the resilient member is elastically-deformable and is in an extended position when the valve member is in the open position.
