Abstract

A medical connector can include a body having a fluid path with an inlet port, an outlet port, a luer portion, and a post extending through a fluid path. An arm having a latch member is coupled to the body to engage a ridge or thread on an exterior surface of a reciprocal connector. The arm may also include an extension. When the connector is in an open position, the latch member restricts retraction of the reciprocal connector from the outlet port. A seal is coupled to the body and includes a flap extending across the outlet port or a bellows to compress along an axis. In a closed position, the post restricts flow through the luer portion. In an open position, the post permits flow through the luer portion.

First claim

What is claimed is:

1. A medical connector comprising:
a body having an inlet port, an outlet port, an inner surface that forms a fluid path from the inlet port to the outlet port, and an outer surface comprising a protrusion; and
a first arm, a second arm, and a bridge that extends between the first and second arms, wherein the bridge comprises a first end proximal to the inlet port, a second end proximal to the outlet port, a slot that extends through the first end of the bridge in a direction toward the second end of the bridge;
wherein the body is positioned between the first and second arms-such that the first and second arms are pivotable relative to the body, and the protrusion is positioned within the slot.

2. The medical connector of claim 1 , wherein the first and second arms each comprise first and second lateral sides, and wherein the bridge is positioned between the first lateral sides of the first and second arms, respectively, and another bridge is positioned between the second lateral sides of the first and second arms, respectively.

3. The medical connector of claim 2 , wherein a crosssectional profile of each of the first and second arms is shaped as an arch extending between the first and second lateral sides thereof.

4. The medical connector of claim 1 , wherein the slot extends entirely through the bridge, from an inner surface of the bridge to an outer surface of the bridge.

5. The medical connector of claim 1 , wherein any of the first and second arms comprise a first end and an opposing second end, and wherein, when the first end of the arm moves away from the body, the second end of the arm is urged toward the body.

6. The medical connector of claim 1 , wherein the body comprises a seal coupled to a circumferential edge of the outlet port and extending laterally inward from the circumferential edge of the outlet port.

7. The medical connector of claim 6 , wherein the seal comprises at least one flap extending from the circumferential edge of the outlet port.

8. The medical connector of claim 1 , wherein the body comprises a luer taper that forms a portion of the fluid path, and wherein the luer taper extends toward the outlet port.

9. The medical connector of claim 1 , wherein the first and second arms are configured to engage against a reciprocal connector to resist movement of the reciprocal connector relative to the body.

10. The medical connector of claim 1 , wherein any of the first and second arms comprises a latch member extending from the arm toward the body.

11. The medical connector of claim 1 , wherein an extension is coupled to any of the first and second arms between a first end of the arm and the protrusion such that when the extension is urged toward the body, the first end is urged away from the body.

12. The medical connector of claim 1 , wherein a first extension is coupled to the first arm, between a first end of the first arm and the protrusion such that when the first extension is urged toward the body, the first end is urged away from the body, and wherein a second extension is coupled to the second arm, between a first end of the second arm and the protrusion such that when the second extension is urged toward the body, the first end is urged away from the body.

13. The medical connector of claim 12 , wherein a distal portion of the first extension extends around an outer surface of the second arm, and wherein a distal portion of the second extension extends around an outer surface of the first arm.

14. The medical connector of claim 1 , wherein the bridge comprises a guide portion extending from the bridge in a direction toward a distal-most end of the body formed by the outlet port, the guide portion comprising a ramp surface extending toward the outlet port.

15. The medical connector of claim 1 , wherein the first arm comprises a first end proximal to the inlet port and a first extension that extends from the first end of the first arm, and the second arm comprises a second end proximal to the outlet port and a second extension that extends from the second end of the second arm.

16. The medical connector of claim 15 , wherein any of the first or second arms extend over the bridge.

17. The medical connector of claim 15 , wherein the first extension extends over the second arm, and the second extension extends over the first arm.

18. A method for providing a medical connector, the method comprising:
providing a body having an inlet port, an outlet port, an inner surface that forms a fluid path from the inlet port to the outlet port, and an outer surface comprising a protrusion; and
providing a first arm, a second arm, and a bridge that extends between the first and second arms, wherein the bridge comprises a first end proximal to the inlet port, a second end proximal to the outlet port, a slot that extends through the first end of the bridge in a direction toward the second end of the bridge;
wherein upon inserting the body between inner surfaces of the first and second arms, respectively, and moving the body in a direction from a second end of the first and second arms, respectively, toward a first end of the first and second arms, respectively, the protrusion is positioned within the slot to pivotably couple the first and second arms to the body.

19. The method of claim 18 , wherein moving the body comprises inserting the protrusion into the slot.

20. A medical connector comprising:
a body having an inlet port, an outlet port, an inner surface that forms a fluid path from the inlet port to the outlet port, and a first mating feature;
a first arm comprising a first lateral side, a second lateral side, and an extension that extends from the first arm to cover a portion of a second arm;
the second arm comprising a first lateral side, a second lateral side, and an extension that extends from the second arm to cover a portion of the first arm; and
a first bridge and a second bridge, wherein the first lateral sides of the first and second arms are pivotably coupled to the first bridge, and the second lateral sides of the first and second arms are pivotably coupled to the second bridge;
wherein the body is positioned between the first and second arms to engage the first mating feature of the body against a second mating feature of each of the first and second bridges such that the first and second arms are pivotable relative to the body.
