<p>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 (27,28,31,56,60), 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.</p> |
