Abstract

A fluid processing system for controlling fluid flow comprises a cassette having a defined passageway on a first side. The first side includes flexible sheeting disposed over the passageway. The system comprises a durable processing device configured to engage the first side of the cassette, the durable processing device comprising a valve actuator configured to engage the flexible sheeting at a valve location along the passageway. The system comprises a first pump configured to draw fluid away from the valve location along the passageway. The first pump is disposed downstream of the valve location. The system comprises a second pump configured to pump fluid towards the valve location along the defined passageway. The second pump is disposed upstream of the valve location. The first and second pumps are configured to operate in concert and configured to provide pressure to prevent collapsing of the flexible sheeting against the passageway during operation.
