PREPACKAGED FLUID PROCESSING MODULE HAVING PUMP AND VALVE ELEMENTS OPERABLE IN RESPONSE TO APPLIED PRESSURES Abstract A disposable prepackaged fluid processing module (20) for deriving plasma from whole blood includes an integral housing (22) wherein anticoagulant (ACD), saline and collection containers (43, 44, and 30), tubing segments (27, 28, 31, 56, and 60), a membrane filter element (141), and other components (63) required in the procedure are contained. Fluid communication between the containers, tubing segments and filter element is provided by a fluid circuit formed by a panel (36) of the housing (22), and an overlying fluid-impermeable flexible sheet member (71). The fluid circuit includes pump and valve elements (130-137) which operate in response to pressures applied to the sheet member. Upon installation of the system in a related actuator apparatus (21), pneumatic actuator ports (100-107) apply pressures to the pump and valve elements to circulate fluid through the fluid circuit.
