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 retainer coupled to the second end of the flexible bag, the retainer having a retention cavity formed thereon that communicates with the compartment of the flexible bag; and an elongated member having a first end rotatably coupled to the first end of the flexible bag and an opposing second end freely disposed within the retention cavity of the retainer so that the second end of the elongated member can rotate within the retention cavity relative to the retainer.
Claims13
A fluid mixing system comprising:
- a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment;
- a retainer coupled to the second end of the flexible bag, the retainer having a retention cavity formed thereon that communicates with the compartment of the flexible bag, wherein the radius of the retainer's retention cavity radially tapers inwardly from an upper end to an opposing lower end;
- and
- a shaft having a first end rotatably coupled to the first end of the flexible bag and an opposing second end freely disposed within and supported by the retention cavity of the retainer so that the second end of the shaft can rotate within the retention cavity relative to the retainer;
- wherein the shaft comprises a steady support portion, two tubular connectors, and an impeller portion;
- wherein the impeller portion has a first end and a second end that are configured to fit within the tubular connectors, and the impeller portion is secured between the tubular connectors;
- wherein the steady support portion has a first end that is configured to fit within a tubular connector of the two tubular connectors and a second end that is freely disposed within and supported by the retention cavity of the retainer.
A fluid mixing system comprising:
- a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment;
- a retainer secured to the second end of the flexible bag, the retainer comprising:
- an outer casing secured to the second end of the flexible bag and bounding a cavity;
- and
- a hub rotatably secured within the cavity of the outer casing, the hub having an opening formed thereon, wherein the radius of the retainer's opening radially tapers inwardly from an upper end to an opposing lower end;
- and
- a shaft having a first end rotatably coupled to the first end of the flexible bag and an opposing second end removably disposed within and supported by the opening of the hub, the shaft engaging the hub so that rotation of the shaft facilitates rotation of the hub relative to the outer casing;
- wherein the shaft comprises a steady support portion, two tubular connectors, and an impeller portion;
- wherein the impeller portion has a first end and a second end that are configured to fit within the tubular connectors, and the impeller portion is secured between the tubular connectors;
- wherein the steady support portion has a first end that is configured to fit within a tubular connector of the two tubular connectors and a second end that is removably disposed within and supported by the opening of the hub.
