Abstract
A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment. A first rotational assembly includes a first casing mounted to the first end of the flexible bag and a first hub rotatably mounted to the first casing. A second rotational assembly includes a second casing mounted to the second end of the flexible bag and a second hub rotatably mounted to the second casing. A connector has a first end coupled with the first hub and an opposing second end coupled with the second hub, the connector being flexible and having a uniform flexibility along its entire length. A first impeller is mounted to the connector.
Claims23
A fluid mixing system comprising:
- a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment;
- a first rotational assembly comprising a first casing mounted to the first end of the flexible bag and a first hub rotatably mounted to the first casing, the first hub having a passageway extending therethrough, at least a portion of the passageway having a polygonal transverse cross section;
- a second rotational assembly comprising a second casing mounted to the second end of the flexible bag and a second hub rotatably mounted to the second casing, the second hub having an opening formed thereon, at least a portion of the opening having a polygonal transverse cross section;
- a tubular connector having a first end coupled with the first hub and an opposing second end coupled with the second hub, the connector bounding a passage extending therethrough, the passage communicating with the passageway of the first hub and the opening of the second hub so as to enable a drive shaft to pass between and into the passageway of the first hub and the opening of the second hub;
- and
- a first impeller mounted to the connector.
A fluid mixing system comprising:
- a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment;
- a first rotational assembly comprising a first casing mounted to the first end of the flexible bag and a first hub rotatably mounted to the first casing;
- a second rotational assembly comprising a second casing mounted to the second end of the flexible bag and a second hub rotatably mounted to the second casing;
- a plurality of spaced apart impellers disposed within the compartment of the flexible bag;
- and
- a plurality of connectors, corresponding ones of the plurality of connectors extending between the first hub and one of the plurality of impellers, between each adjacent pair of the plurality of impellers, and between the second hub and one of the plurality of impellers, wherein the plurality of connectors extending between the first hub and the second hub are only connected together through the impellers.
A fluid mixing system comprising:
- a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment;
- a first rotational assembly comprising a first casing mounted to the first end of the flexible bag and a first hub rotatably mounted to the first casing;
- a second rotational assembly comprising a second casing mounted to the second end of the flexible bag and a second hub rotatably mounted to the second casing;
- a connector having a first end coupled with the first hub and an opposing second end coupled with the second hub, the connector being sufficiently flexible that the connector can be coiled;
- and
- a first impeller mounted to the connector.
