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, defining a proximal-most end, an outlet port defining a distal-most end, a cavity that extends from the outlet port toward the inlet port, a luer taper that extends into the cavity toward the outlet port, a fluid path from the inlet port through the luer taper to the outlet port;
a seal coupled to a circumferential edge of the outlet port and extending laterally inward from the circumferential edge of the outlet port toward the luer taper to at least partially enclose the cavity; and
a first arm, a second arm, and a bridge that extends between the first and second arms, wherein an outer surface of the body comprises any of a protrusion or a slot, and the bridge comprises the other of the protrusion or the slot, such that the protrusion is positioned within the slot to pivotably couple the first and second arms to the body, and 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.

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

3. The medical connector of claim 2 , wherein the latch member comprises a ramp surface, an engagement surface extending transversely to the ramp surface, and an apex area that transitions between the ramp surface and the engagement surface.

4. The medical connector of claim 1 , wherein the 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.

5. The medical connector of claim 1 , wherein the seal comprises at least one flap extending from the circumferential edge of the outlet port.

6. The medical connector of claim 5 , wherein a length of the at least one flap from the circumferential edge of the outlet port is less than a distance between the circumferential edge of the outlet port and the luer taper, such that the at least one flap is free from the luer taper when the at least one flap is displaced into the body.

7. The medical connector of claim 1 , wherein the protrusion and the slot are positioned between the inlet port and the outlet port.

8. The medical connector of claim 7 , wherein an extension is coupled to the 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.

9. The medical connector of claim 1 , wherein the bridge comprises a guide portion extending toward the distal-most end, the guide portion comprising a ramp surface extending toward the outlet port.

10. A medical connector comprising:
a body having an inlet port, an outlet port, a cavity that extends from the outlet port toward the inlet port, a luer taper that extends into the cavity, a fluid path from the inlet port through the luer taper to the outlet port, and a protrusion that extends from an outer surface of the body; and
a first arm and a second arm, pivotably coupled to the body and a bridge therebetween, the bridge comprising an elongated slit extending through the bridge partially toward the outlet port, and configured to receive the protrusion within the elongated slit.

11. The medical connector of claim 10 , further comprising a seal coupled to the body at the outlet port, wherein the seal extends from the outlet port toward the luer taper.

12. The medical connector of claim 11 , wherein the seal comprises at least one flap extending from the outlet port, the flap having a length between the outlet port toward the luer taper, wherein the length is less than a distance between the outlet port and the luer taper, such that the flap is free from the luer taper when the flap is displaced into the body.

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

14. The medical connector of claim 13 , wherein the latch member comprises a ramp surface, an engagement surface extending transversely to the ramp surface, and an apex area that transitions between the ramp surface and the engagement surface.

15. The medical connector of claim 10 , 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.

16. The medical connector of claim 10 , 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.

17. The medical connector of claim 10 , 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.
