Abstract

A first flow path (78) is defined within a first panel that forms part of an extracorporeal fluid circuit (56). A second flow path is defined within a second panel that also forms a part of the extracorporeal fluid circulation. The first and second panels are oriented in a fluid processing cartridge (18) for mounting as an integrated unit on a fluid processing machine (16) and for removal as an integrated unit from the fluid processing machine.
