Abstract
In a vessel, such as a flexible bag, a fluid is received and agitated using an internal fluid-agitating element driven by an external motive device and supported by a bearing, such as a roller bearing.
Claims34
An apparatus intended for receiving a fluid and a rotatable fluid-agitating element, comprising:
- a collapsible bag including an interior compartment capable of receiving and holding the fluid and the fluid-agitating element;
- and
- a roller bearing adapted for providing low-friction support for the fluid-agitating element in the interior compartment of the bag.
A method of forming an assembly for agitating a fluid, comprising:
- providing a collapsible bag for receiving a magnetic fluid-agitating element;
- and
- supporting the fluid-agitating element on a roller bearing in the bag.
An apparatus intended for receiving and agitating a fluid, comprising:
- a collapsible bag including an interior compartment for receiving the fluid;
- and
- a magnetic fluid-agitating element positioned in the interior compartment of the bag;
- wherein the bag includes a tube extending into the interior compartment and supports a roller bearing for use in rotating the fluid-agitating element in the bag.
A method of positioning a fluid-agitating element in a bag intended for receiving a fluid in need of agitation, comprising:
- supporting the fluid-agitating element in the vessel with a roller bearing that bodily rotates relative to the bag.
An apparatus intended for receiving and mixing a fluid, comprising:
- a fluid-agitating element;
- a collapsible bag capable of receiving the fluid and the fluid-agitating element;
- and
- a roller bearing for providing low-friction support for the fluid-agitating element.
An apparatus intended for receiving and mixing a fluid, comprising:
- a magnetic fluid-agitating element;
- a bag capable of receiving the fluid, said bag including a flexible wall carrying a rigid receiver for receiving the fluid-agitating element;
- and
- a bearing for providing low-friction support for the magnetic fluid-agitating element.
An apparatus intended for receiving and agitating a fluid, comprising:
- a flexible bag having an interior compartment adapted for receiving the fluid under sterile conditions;
- and
- a rotatable fluid-agitating element positioned in the interior compartment;
- wherein the bag includes a wall forming a cavity and a bearing adapted for promoting rotation of the fluid-agitating element.
An apparatus intended for receiving and mixing a fluid, comprising:
- a fluid-agitating element;
- a bag having an interior compartment capable of receiving the fluid and the fluid-agitating element under sterile conditions;
- a shaft projecting into the interior compartment for driving the fluid-agitating element;
- and
- at least one roller bearing associated with the shaft.
