Abstract

A method of installing a flexible bioprocess container in a bioprocessing system having a rigid housing with an interior compartment and extending between a top and an opposing base. The method includes coupling a first surface of the flexible bioprocess container to a moveable platform positioned within the interior compartment of the rigid housing; coupling a second surface of the flexible bioprocess container to the base of the rigid housing; and moving the movable platform relative to the rigid housing and toward the top of the rigid housing so as to at least partially expand the flexible bioprocess container within the interior compartment of the rigid housing.

First claim

What is claimed is:

1 . A method of installing a flexible bioprocess container in a bioprocessing system comprising a rigid housing having an interior compartment and extending between a top and an opposing base, the method comprising:
coupling a first surface of the flexible bioprocess container to a moveable platform positioned within the interior compartment of the rigid housing, wherein coupling the first surface of the flexible bioprocess container to the moveable platform comprises coupling a first bearing housing disposed on the first surface to the moveable platform; coupling a second surface of the flexible bioprocess container to the base of the rigid housing, wherein coupling the second surface of the flexible bioprocess container to the base comprises coupling a second bearing housing disposed on the second surface to a catch assembly disposed on the base; and moving the moveable platform relative to the rigid housing and toward the top of the rigid housing so as to at least partially expand the flexible bioprocess container within the interior compartment of the rigid housing.

2 . The method as recited in claim 1 , further comprising rotating a drive assembly within the flexible bioprocess container after moving the moveable platform toward the top of the rigid housing, the drive assembly being coupled to the first surface of the flexible bioprocess container and to the second surface of the flexible bioprocess container.

3 . The method as recited in claim 1 , wherein the catch assembly comprises:
a catch plate having a protruding cam; and a cam plate having a cam guide that engages the protruding cam, wherein the cam plate moves between a first and a second position on a first axis and the catch plate moves between a first and a second position on a second axis and the first positions of the plates correspond to an open position of the catch assembly and the second positions of the plates correspond to a closed position of the catch assembly.

4 . The method as recited in claim 3 , wherein the catch assembly further comprises a spring loaded inhibitor plate, comprising:
a projection; a spring configured to extend the projection into an opening in the catch assembly; and a groove having an elongated region and a slot, wherein a dowel protruding from the cam plate engages the groove, wherein when the opening is unoccupied the dowel is restricted to the slot and the catch assembly stays in the closed position and when the opening is occupied by the second bearing housing, the inhibitor plate retracts and the dowel can enter the elongated region to close the catch assembly.

5 . The method as recited in claim 1 , further comprising rotating a drive assembly within the flexible bioprocess container after moving the moveable platform toward the top of the rigid housing, the drive assembly extending between the first bearing housing and the second bearing housing.

6 . The method as recited in claim 4 , wherein the drive assembly comprises one or more impellers.

7 . The method as recited in claim 1 , further comprising coupling a drive shaft extending from the first bearing housing to a bearing housing retention assembly mounted on the moveable platform, the bearing housing retention assembly being configured to rotate the drive shaft.

8 . The method as recited in claim 1 , further comprising:
coupling the first bearing housing to a bearing housing retention assembly mounted on the moveable platform; and activating a motor of the bearing housing retention assembly so as to rotate a drive assembly disposed within the flexible bioprocess container and extending between the first bearing housing and the second bearing housing.

9 . The method as recited in claim 1 , further comprising a tube management plate having a plurality of openings extending therethrough and a plurality of tubes extending from the flexible bioprocess container and passing through the plurality of openings, the method further comprising passing a portion of the second bearing housing through a bearing receiver opening extending through the tube management plate.

10 . The method as recited in claim 9 , further comprising positioning the tube management plate within an opening formed on the base of the rigid housing.

11 . The method as recited in claim 10 , further comprising securing a perimeter edge of the tube management plate within a groove bounding the opening formed on the base.

12 . The method as recited in claim 1 , further comprising coupling a tube extending from the flexible bioprocess container to a condenser mounted on the moveable platform.

13 . The method as recited in claim 1 , wherein moving the moveable platform comprises manipulating cables attached to the moveable platform and passing over pulleys disposed on the rigid housing.

14 . The method of claim 13 , wherein manipulating the cables includes activating a motive force device coupled to the cables and secured to the rigid housing.

15 . The method as recited in claim 1 , further comprising securing cables of two retractable cable assemblies disposed on the rigid housing to corresponding connectors disposed on the flexible bioprocess container.

16 . The method as recited in claim 1 ,
wherein coupling the first surface of the flexible bioprocess container to the moveable platform comprises coupling a first connector disposed on the first surface to the moveable platform; and wherein coupling the second surface of the flexible bioprocess container to the base comprises coupling a second connector disposed on the second surface to the base.
