Abstract
A multi-tubing pinch valve assembly including a receiving space defined between a pinch protrusion and tubing contact body. The multi-tubing pinch valve assembly is moveable between a retracted state and an extended state. In the extended state, multiple tubes disposed in the receiving space are pinched, restricting flow therethrough. In the retracted state, multiple tubes are capable of being loaded into and/or out of the receiving space.
Claims19
A multiple-tube pinch valve assembly comprising:
- a frame configured to hold a plurality of bioreactors and tubing connected to the bioreactors;
- a base configured to support the frame, the base including a plurality of pinch protrusions;
- and
- a plurality of actuators included with the base, each one of the plurality of actuators is connected to, and configured to actuate, a different one of the plurality of pinch protrusions;
- wherein:
- the frame and the base are configured to cooperate to retain the frame on the base and orient the frame such that the plurality of pinch protrusions are opposite to, and perpendicular to, the tubing connected to the bioreactors;
- the plurality of actuators are configured to individually actuate each one of the plurality of pinch protrusions between a retracted position and an extended position, in the retracted position the pinch protrusions are spaced apart from the tubing, in the extended position the plurality of pinch protrusions pinch the tubing to restrict fluid flow through the tubing;
- and
- the pinch protrusions are oriented such that in the extended position the pinch protrusions bend the tubing.
A multiple-tube pinch valve assembly configured to cooperate with a frame holding a plurality of bioreactors and tubing connected to the bioreactors, the multiple-tube pinch valve assembly comprising:
- a plurality of hinge plates, each one of the plurality of hinge plates including a hinge pinch protrusion;
- a plurality of actuators, each one of the plurality of actuators is connected to, and configured to actuate, a different one of the plurality of hinge plates;
- and
- mounts configured to cooperate with the frame to support and orientate the frame such that the tubes are opposite to, and extend perpendicular to, the hinge pinch protrusions;
- wherein the plurality of actuators are configured to individually actuate each one of the plurality of hinge plates between a retracted position and an extended position, in the retracted position the hinge pinch protrusions are spaced apart from the tubing, in the extended position the hinge pinch protrusions pinch the tubing to restrict fluid flow through the tubing.
A multiple-tube pinch valve assembly configured to cooperate with a frame holding a plurality of bioreactors and tubing connected to the bioreactors, the multiple-tube pinch valve assembly comprising:
- a plurality of pinch protrusions;
- a plurality of actuators, each one of the plurality of actuators is connected to, and configured to actuate, a different one of the plurality of pinch protrusions;
- and
- a rail supported over the pinch protrusions, the rail configured to cooperate with the frame to support the frame over the pinch protrusions and orientate the frame such that the tubes are opposite to, and extend perpendicular to, the pinch protrusions;
- wherein the plurality of actuators are configured to individually actuate each one of the plurality of pinch protrusions between a retracted position and an extended position, in the retracted position the pinch protrusions are spaced apart from the tubing, in the extended position the pinch protrusions pinch the tubing against the rail to restrict fluid flow through the tubing.
