Abstract

A fluid transfer hub has a first vessel closure, a second vessel closure, a gasket arranged between the first vessel closure and the second vessel closure, and a clamp at least partially surrounding the first vessel closure, the second vessel closure, and the gasket. The first vessel closure has a first body, one or more apertures extending axially through the first body, one or more first inserts extending axially through the one or more apertures, and a cast seal disposed within the first body and surrounding each first insert. The second vessel closure has a second body, one or more apertures extending axially through the second body, one or more second inserts extending axially through the one or more apertures, and a cast seal disposed within the second body and surrounding each second insert.

First claim

The invention claimed is:

1. A fluid distribution hub, comprising:
a first vessel closure having a first body, the first body defining a first aperture extending axially through the first body, the first aperture configured to sealingly attach a first insert to the first body;
a second vessel closure having a second body, the second body defining a second aperture extending axially through the second body and a third aperture extending axially through the second body, the second aperture configured to sealingly attach a second insert to the second body, the third aperture configured to sealingly attach a third insert to the second body;
a gasket arranged between the first vessel closure and the second vessel closure; and
a clamp at least partially surrounding the first vessel closure, the second vessel closure, and the gasket, the clamp securing the first vessel closure to the second vessel closure with the gasket disposed between the first vessel closure and the second vessel closure, a chamber defined between the first vessel closure and the second vessel closure, the gasket bisecting the chamber.

2. The fluid distribution hub according to claim 1 , wherein the gasket comprises one of a screen gasket, a perforated plate gasket, and an orifice gasket.

3. The fluid distribution hub according to claim 1 , further comprising a first cast seal bonding the first insert to the first aperture and a second cast seal bonding at least one of the second insert to the second aperture or the third insert to the third aperture.

4. The fluid distribution hub according to claim 3 , wherein the first cast seal aseptically bonds and seals the first insert to the first aperture the second cast seal aseptically bonds and seals the second insert to the second aperture.

5. The fluid distribution hub according to claim 3 , further comprising a third cast seal bonding the third insert to the third aperture, the second cast seal bonding the second insert to the second aperture.

6. The fluid distribution hub according to claim 3 , wherein the first cast seal and the second cast seal are formed by a liquid silicone casting agent or perfluorpolyether.

7. The fluid distribution hub according to claim 1 , further comprising one or more anchors, each of the one or more anchors adhesively attached to a respective aperture of the second body.

8. The fluid distribution hub according to claim 7 , wherein the one or more anchors are constructed from material selected from the group consisting of metal, plastic, glass-filled plastic, ceramics, and composites.

9. The fluid distribution hub according to claim 1 , wherein at least one of the first insert, the second insert, or the third insert comprise tubing.

10. The fluid distribution hub according to claim 9 , wherein at least one of the first insert, the second insert, or the third insert comprise silicone tubing.

11. The fluid distribution hub according to claim 9 , further comprising a sleeve surrounding at least a portion of the second insert or the third insert.

12. The fluid distribution hub according to claim 11 , wherein the sleeve is formed of a material having plasticity such that pressure applied to the sleeve causes the sleeve to attach and seal the second insert or the third insert to the respective aperture.

13. The fluid distribution hub according to claim 12 , wherein the sleeve is adhesively attached to the second insert or the third insert.

14. The fluid distribution hub according to claim 1 , wherein, the gasket fully separates the first vessel closure and the second vessel closure from one another.

15. A fluid distribution hub, comprising:
a first vessel closure having a first body, the first body defining a first aperture extending axially through the first body, the first aperture including a first cast seal configured to sealingly attach a first tube to the first aperture;
a second vessel closure having a second body, the second body defining a second aperture extending axially through the second body and a third aperture extending axially through the second body, the second body including a second cast seal configured to sealingly attach a second tube to the second aperture or a third tube to the third aperture;
a gasket arranged between the first vessel closure and the second vessel closure; and
a clamp at least partially surrounding the first vessel closure, the second vessel closure, and the gasket, the clamp securing the first vessel closure to the second vessel closure with the gasket disposed between the first vessel closure and the second vessel closure.

16. The fluid distribution hub according to claim 15 , further comprising:
a first tube sealingly attached to the first aperture by the first cast seal;
a second tube sealingly attached to the second aperture by the second cast seal; and
a third tube sealingly attached to the third aperture.

17. The fluid distribution hub according to claim 16 , wherein the first cast seal aseptically bonds and seals the first tube to the first aperture the second cast seal aseptically bonds and seals the second tube to the second aperture.

18. A method of manufacturing a fluid distribution hub, the method comprising:
positioning a gasket between a first vessel closure and a second vessel closure such that the gasket bisects a chamber defined between the first vessel closure and the second vessel closure, the first vessel closure having a first body, the first body defining a first aperture extending axially through the first body and a first insert sealingly attached to the first aperture, the second vessel closure having a second body, the second body defining a second aperture extending axially through the second body and a third aperture extending axially through the second body, the second vessel closure including a second insert sealingly attached to the second aperture and a third insert sealingly attached to the third aperture; and
securing the first vessel closure to the second vessel closure with a clamp at least partially surrounding the first vessel closure, the second vessel closure, and the gasket.

19. The method of manufacturing according to claim 18 , further comprising creating the first vessel closure including bonding the first insert to the first aperture with a cast seal.

20. The method of manufacturing according to claim 18 , further comprising creating the second vessel closure including bonding the second insert to the second aperture or the third insert to the third aperture with a cast seal.
