Abstract

A blood component collection system with optimization capabilities. In one embodiment, the blood component collection system includes a central input station (e.g., computer) and a plurality of blood component collection assemblies. These blood component collection assemblies include a blood component collection device and an operator interface module (e.g., computer). Various types of data are maintained on the collection procedures performed in the blood component collection system and are utilized to generate various types of reports for optimizing system operations.
