Abstract

A syringe-to-syringe coupling for facilitating the transfer of fluids or medications from a first syringe to a second syringe. In example embodiments, the coupling includes a centrally-positioned hub extending from a first end to a second end, and a fluid delivery conduit provided within the hub and extending between the first and second ends. In example forms, each end of the hub includes a male tip.

First claim

What is claimed is:

1. A coupling for facilitating the transfer of fluids or medications, the coupling comprising:
a centrally-positioned hub extending from a first end to a second end, each end of the hub comprising a male tip;
a fluid delivery conduit provided within the hub and extending between the first and second ends; and
a body outwardly offset from the hub;
at least one connecting member connecting the hub with the body; and
at least one engagement member for providing coupling engagement with a syringe, wherein the at least one engagement member extends from the at least one connecting member.

2. The coupling of claim 1 , wherein at least one of the male tips comprise a male ENFit coupling.

3. The coupling of claim 1 , wherein the at least one engagement member is configured for removable coupling engagement with the syringe.

4. The coupling of claim 1 , wherein the at least one engagement member is configured for permanent coupling engagement with the syringe.

5. The coupling of claim 1 , wherein one of the first or second ends of the hub is in the form of a luer connector for connection with a tube set of a syringe fill pump, and wherein the other of the ends is in the form of an ENFit connector for connection with an ENfit female connector of a syringe.

6. The coupling of claim 1 , wherein the at least one engagement member comprises a clip having a rib extending from an internal surface thereof.

7. The coupling of claim 1 , wherein the at least one engagement member comprises four clips.

8. The coupling of claim 7 , wherein at least one of the four clips comprises a rib extending from an internal surface thereof.

9. The coupling of claim 8 , wherein the rib extends along a helical path to provide for removable engagement with the one or more lugs of the female connector of at least one of the syringes.

10. The coupling of claim 8 , wherein the rib extends along a horizontal path to provide for permanent engagement with the one or more lugs of the female connector of at least one of the syringes.

11. The coupling of claim 1 , wherein the body comprises two generally planar members oppositely-positioned and outwardly offset from the hub.

12. The coupling of claim 11 , wherein the planar members are generally rectangular in shape.

13. The coupling of claim 11 , wherein the at least one engagement member extends from an internal surface of at least one of the planar members for providing engagement with the one or more lugs of a female connector of at least one of the syringes.

14. The coupling of claim 1 , wherein the at least one engagement member comprises a collar member comprising threads formed on an internal portion thereof, and wherein the threads are configured for removable engagement with the one or more lugs of a female connector of at least one of the syringes.
