Abstract
A system for collecting and processing donated blood comprises a first porous medium interposed between a blood collection bag and a satellite bag and a second porous medium interposed between the blood collection bag and another satellite bag. The porous media are leucocyte depletion media. The system may also include one or more of the following: a red cell barrier medium, a separation medium, a gas inlet, and a gas outlet. The system can be used to centrifuge whole blood into one or more components, and includes a means for protecting the system during centrifugation.
