Abstract
A disposable prepackaged fluid processing module includes an integral housing wherein fluid containers, tubing segments, and other components required in processing a fluid are contained. Fluid communication between the containers, components and tubing segments is provided by a fluid circuit formed by a panel of the housing, and an overlying fluid-impermeable flexible sheet member. The fluid circuit includes pump and valve elements which operate in response to pressures applied to the sheet member. Upon installation of the system in a related actuator apparatus pneumatic actuator ports apply pressures to the pump and valve elements to circulate fluid through the fluid circuit.
