Abstract
A fluid processing apparatus for use in conjunction with a prepackaged disposable fluid processing module of the type which includes an integral housing wherein fluid containers, tubing segments, and other components required in processing a fluid are contained, and wherein fluid communication between the containers, components and tubing segments is provided by a fluid circuit formed within the housing by a first relatively inflexible fluid-impervious sheet member and a second relatively flexible fluid-impermeable sheet member. The fluid circuit includes pump and valve elements which operate in response to pressures applied to the second sheet member. Upon installation of the system in the processing apparatus pneumatic actuator ports apply pressures to the second sheet member through access apertures in the housing to circulate fluid through the fluid circuit.
