Abstract
A fluid mixing system includes a container, such as a flexible bag, bounding a compartment. A flexible drive line is disposed within the compartment, the drive line having a first end rotatably connected to a first end of the container and an opposing second end rotatably connected to a second end of the container. At least one mixing element, such as an impeller, is coupled with the flexible drive line. Rotation of the drive line facilitates rotation of the impeller within the container.
Claims20
A fluid mixing system comprising:
- a container bounding a sterile compartment, the container having a first end and an opposing second end;
- a flexible drive line disposed within the sterile compartment, the flexible drive line having a length extending between a first end and an opposing second end, the first end of the drive line being rotatably connected to the first end of the container and the opposing second end of the drive line being rotatably connected to the second end of the container, at least 40% of the length of the drive line being sufficiently flexible that it can be twisted under torsion over an angle of at least 180% without plastic deformation;
- and
- at least one mixing element coupled with the flexible drive line.
