Abstract
Embodiments of the present disclosure are directed to a fluid connection including a plurality of flexible polymeric tubes; an integral fluid connector coupled to and in fluid communication with each of the plurality of tubes; and a shell disposed over and encapsulating the fluid connector. The fluid connection surprisingly exhibiting significant increases in the working pressure, particularly in biopharmaceutical fluid transfer systems.
Claims17
A fluid connection comprising:
- a. a plurality of flexible polymeric tubes;
- b. an integral fluid connector coupled to and in fluid communication with each of the plurality of tubes, wherein the fluid connector is covalently bonded to the tubes,
- c. a shell disposed over and encapsulating the fluid connector, wherein the fluid connection has a working pressure of at least about 120 psi, wherein the shell is overmolded over the fluid connector such that the fluid connector is essentially encapsulated by the shell.
An autoclavable biopharmaceutical fluid connection comprising:
- a. a plurality of silicone reinforced tubes;
- b. an integral silicone fluid connecter coupled to the plurality of tubes such that there is an essentially seamless transition between the inner cavity of the plurality of tubes and the fluid connector, and wherein the fluid connector is covalently bonded to the tubes;
- and
- c. a polypropylene shell disposed over and encapsulating fluid connector, wherein the fluid connection has a working pressure of at least about 120 psi.
A method of forming a fluid connection, the method comprising:
- a. providing a plurality of tubes;
- b. integrally forming a fluid connector about the plurality of tubes, wherein the fluid connector is covalently bonded to the tubes;
- c. forming a shell over and encapsulating the fluid connector, wherein the fluid connection has a working pressure of at least about 120 psi, wherein forming a shell comprises overmolding the shell over the fluid connector such that the fluid connector is essentially encapsulated by the shell.
