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, and an inner surface that forms a fluid path from the inlet port to the outlet port; 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, and 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, wherein the protrusion and the slot are elongate along a longitudinal axis defined between the inlet port and the outlet port of the body, and wherein the first and second arms are pivotable relative to the body, and 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 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 crossectional 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 bridge comprises the slot, and the outer surface of the body comprises the protrusion.

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

6 . The medical connector of claim 1 , wherein each of the first and second arms comprise a first end and an opposing second end, and wherein, when any of the first or second arms is pivoted such that the second end of the arm moves in a direction toward the body, the first end of the arm moves in a direction away from the body.

7 . The medical connector of claim 1 , wherein the body comprises a seal coupled to a circumferential edge of the outlet port and extending in a direction toward the longitudinal axis defined between the inlet port and the outlet port.

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

9 . 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.

10 . The medical connector of claim 1 , wherein the first and second arms are configured to engage against the reciprocal connector to resist axial movement of the reciprocal connector along the longitudinal axis defined between the inlet port and the outlet port of the body.

11 . The medical connector of claim 10 , wherein the first and second arms are configured to engage against the reciprocal connector and permit the reciprocal connector to rotate, relative to the body, around the longitudinal axis defined between the inlet port and the outlet port of the body.

12 . The medical connector of claim 1 , wherein any of the first and second arms comprises a latch member extending from the arm toward the longitudinal axis defined between the inlet port and the outlet port of the body.

13 . 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.

14 . 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.

15 . The medical connector of claim 14 , wherein a distal portion of the first extension extends along an outer surface of the second arm, and wherein a distal portion of the second extension extends along an outer surface of the first arm.

16 . 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.

17 . 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 any of a protrusion or a slot; 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, and the other of the protrusion or the slot, wherein the protrusion and the slot are elongate along a longitudinal axis defined between the inlet port and the outlet port of the body; wherein upon inserting the body between inner surfaces of the first and second arms such that the protrusion is engaged against the slot, the first and second arms are pivotably coupled to the body.

18 . The method of claim 17 , wherein inserting the body between inner surfaces of the first and second arms comprises 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.

19 . 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; and a first arm and a second arm, wherein each of the first and second arms extend along an outer surface of the body and comprise a second mating feature engaged against the first mating feature; wherein the first mating feature and the second mating feature are elongate along a longitudinal axis defined between the inlet port and the outlet port of the body, and the first and second arms are pivotable relative to the body such that a first end of the first or second arm, proximal to the inlet port, moves in a direction away from the inlet port when a second end of the first or second arm, proximal to the outlet port, moves in a direction toward the outlet port.

20 . The medical connector of claim 19 , wherein the first mating feature comprises any of slot or a protrusion, and the second mating feature comprises the other of the slot or protrusion.
