Abstract

Some embodiments relate to a luer connector comprising a housing having a hollow bore therethrough, a first end, and a second end, a male luer tip supported by the housing configured to rotate with respect to the housing, the luer tip having a first open end and a passageway through the luer tip in fluid communication with the first open end, and a substantially rigid internal member extending into the passageway of the luer tip toward the first open end of the luer tip. In some embodiments, at least one of the luer tip and the internal member can be axially moveable between a first closed position and a second open position relative to the other of the luer tip and the internal member. Further, the luer tip and the internal member can cooperate such that rotation of the luer tip in a first direction relative to the housing increases an axial displacement between the first open end of the luer tip and an end portion of the internal member.

Claims

1. A closeable connector configured to receive a separate medical article and to transition between an open position and a closed position, the closeable connector comprising:

a housing comprising;

a proximal housing portion comprising a port, and

a distal housing portion comprising a luer tip and a shroud, the luer tip comprising a fluid passageway and a distal end portion having a distal opening passing therethrough, the fluid passageway extending at least partially through the luer tip, the shroud surrounding at least a portion of the luer tip and comprising inner threads configured to removably attach the closeable connector with the separate medical article;

a valve member comprising;

a valve base being located on a proximal portion of the valve member,

an actuating member extending from the valve base toward the distal opening of the distal housing portion such that the actuating member is at least partially positioned between the shroud and the luer tip of the distal housing portion, the actuating member configured to facilitate transition of the closeable connector from the closed position to the open position, and

a generally tubular projection extending from the valve base and into at least a portion of the fluid passageway of the luer tip, the generally tubular projection being configured to translate axially within the luer tip between a first position and a second position, the generally tubular projection comprising a first end configured to engage with the distal end portion of the luer tip such the closeable connector is in the closed position when the generally tubular projection is in the first position,

wherein the closeable connector is configured to inhibit fluid flow through the distal opening of the luer tip when in the closed position, and

wherein the closeable connector is configured to permit fluid flow through the distal opening, around the first end of the generally tubular projection, and along at least a portion of the generally tubular projection when in the open position; and

a resilient member comprising an outer portion circumferentially extending along and being supported by an interior surface the housing between the proximal housing portion and the distal housing portion such that the resilient member at least partially extends within the proximal housing portion, the resilient member being configured to engage at least a portion of the valve base of the valve member to facilitate transition of the generally tubular projection between the first position and the second position such that the closeable connector transitions between the closed position and the open position,

wherein the resilient member biases the generally tubular projection towards the first position and the closeable connector towards the closed position, and

wherein the resilient member and the proximal housing portion at least partially define an internal chamber comprising a fluid volume configured to increase in volume as the valve member transitions from the second position to the first position.

2. The closeable connector of claim 1, wherein the resilient member further comprises an opening configured to permit fluid flow through the resilient member.

3. The closeable connector of claim 1, wherein the generally tubular projection further comprises an internal fluid flow passageway.

4. The closeable connector of claim 1, wherein the interior surface of the housing at least partially defines an annular depression configured to receive the outer portion of the resilient member.

5. The closeable connector of claim 1, wherein the outer portion of the resilient member is positioned at a location radially outward from the inner threads of the shroud relative to a longitudinal axis of the generally tubular projection.

6. The closeable connector of claim 1, wherein the resilient member comprises an inner portion, and wherein the inner portion extends along at least a portion of the valve base to engage the valve member with the resilient member.

7. The closeable connector of claim 6, wherein the inner portion of the resilient member is coupled to the valve base of the valve member.

8. The closeable connector of claim 1, wherein the resilient member is in an extended position when the closeable connector is in the open position.

9. The closeable connector of claim 1, wherein resilient member is located proximal from the shroud.

10. The closeable connector of claim 1, wherein resilient member is a diaphragm.

11. The closeable connector of claim 1, wherein the first end of the generally tubular projection comprises protrusions configured to facilitate engagement of the generally tubular projection with the distal end portion of the luer tip and facilitate transition of the closeable connector to the closed position.

12. The closeable connector of claim 1, wherein increasing the fluid volume within the internal chamber is configured to generate reduced pressure within the internal chamber to facilitate the passage of fluid from the luer tip into the internal chamber as the closeable connector transitions from the open position to the closed position.

13. The closeable connector of claim 1 further comprising a sealing member configured to provide seal between the valve member and the distal housing portion, the sealing member extending generally around at least a portion of the valve member when the closeable connector is in the open position and in the closed position.

14. The closeable connector of claim 1, wherein the actuating member is integrally formed with the valve base.

15. The closeable connector of claim 1, wherein the luer tip remains stationary relative to the housing as the closeable connector transitions between the open position and the closed position.

16. The closeable connector of claim 1, wherein the actuating member comprises two struts, and wherein a first strut is positioned at a location diametrically opposed to a second strut.

17. The closeable connector of claim 1, wherein the port of the proximal housing portion comprises a female luer component configured to receive a male luer component of a separate medical implement.

18. The closeable connector of claim 1, further comprising a sealing member configured to provide seal between the valve member and the distal housing portion, the sealing member extending generally around at least a portion of the valve member when the closeable connector is in the open position and in the closed position,

wherein the port of the proximal housing portion comprises a female luer component configured to receive a male luer component of a separate medical implement,

wherein the interior surface of the housing at least partially defines an annular depression configured to receive the outer portion of the resilient member,

wherein the resilient member comprises an inner portion extending along at least a portion of the valve base to engage the valve member with the resilient member, and

wherein increasing the fluid volume within the internal chamber is configured to generate reduced pressure within the internal chamber to facilitate the passage of fluid from the luer tip into the internal chamber as the closeable connector transitions from the open position to the closed position.
