Abstract

A leak-proof fluid transfer assembly including a thermoplastic tube, a thermoset tube, and connector coupling the thermoplastic tube and the thermoset tube, where the fluid transfer assembly is adapted to maintain a substantially leak-proof fluid connection between the thermoplastic tube and the thermoset tube after autoclave sterilization.

First claim

What is claimed is:

1. A leak-proof fluid transfer assembly comprising:
a thermoplastic tube;
a thermoset tube;
a connector coupling the thermoplastic tube and the thermoset tube, wherein the connector comprises a plurality of barbs adapted to grip an inner diameter of the thermoplastic tube,
wherein the fluid transfer assembly is adapted to maintain a substantially leak-proof fluid connection between the thermoplastic tube and the thermoset tube after autoclave sterilization, wherein at least one of the plurality of barbs includes one or more bumps, and wherein the connector comprises a first coupling structure on an outer diameter of the thermoplastic tube and a second coupling structure on an outer diameter of the thermoset tube, wherein at least one of the first coupling structure of the second coupling structure comprises polyvinylidene difluoride (PFDF).

2. The fluid transfer assembly of claim 1 , wherein the thermoplastic tube includes a thermoplastic elastomer comprising a styrene-based block copolymer, a thermoplastic olefin-based elastomer, a thermoplastic vulcanizate (TPV), a thermoplastic polyester-based elastomer, or any combination thereof.

3. The fluid transfer assembly of claim 1 , wherein the connector is adapted to provide a fluid communication between the thermoplastic tube and the thermoset tube.

4. The fluid transfer assembly of claim 1 , wherein the connector includes a material adapted for biopharmaceutical applications.

5. The fluid transfer assembly of claim 1 , wherein the connector comprises a polypropylene.

6. The fluid transfer assembly of claim 1 , wherein the thermoset tube includes a tube comprising a polyurethane elastomer, a silicone elastomer, or a combination thereof.

7. The fluid transfer assembly of claim 1 , wherein the thermoset tube includes a tube comprising a silicone elastomer.

8. The fluid transfer assembly of claim 1 , wherein the fluid transfer assembly is adapted to maintain an aseptic connection between the thermoplastic tube and the thermoset tube after autoclaving.

9. The fluid transfer assembly of claim 1 , wherein the fluid transfer assembly has a Submerged Leak Test rating of at least 75%.

10. The fluid transfer assembly of claim 1 , wherein the fluid transfer assembly has an Autoclaved Submerged Leak Test rating of at least 75%.

11. The fluid transfer assembly of claim 1 , wherein the thermoplastic tube has an inner diameter of at least 0.4 cm.

12. The fluid transfer assembly of claim 1 , wherein the thermoplastic tube has an inner diameter of no greater than 10 cm.

13. The fluid transfer assembly of claim 1 , wherein the connector has an inner diameter that is substantially the same as the inner diameter of the thermoplastic tube, of the thermoset tube, or of both.

14. The fluid transfer assembly of claim 1 , wherein at least one of the other of the first coupling structure or the second coupling structure comprises polypropylene.

15. The fluid transfer assembly of claim 1 , wherein the connector comprises a thermoplastic polymer.

16. The fluid transfer assembly of claim 1 , wherein the connector has an inline configuration.

17. The fluid transfer assembly of claim 1 , wherein at least one of the plurality of barbs includes one or more continuous ridges.

18. The fluid transfer assembly of claim 1 , wherein the thermoset tube includes a tube comprising a polyurethane elastomer.

19. The fluid transfer assembly of claim 1 , wherein the connector comprises an external rib that abuts an end of the thermoplastic tube.

20. The fluid transfer assembly of claim 19 , wherein the first coupling structure overmolds the external rib of the connector.
