APPARATUS AND METHOD FOR AUTOMATICALLY LOADING WASHING SOLUTION IN A MULTI-UNIT BLOOD PROCESSOR

摘要

A method and apparatus for separating at least two discrete volumes of a composite liquid into at least a first component and a second component and automatically washing at least one component on a centrifuge rotor. The method comprises transferring a wash solution from a wash solution bag on the rotor into a separation bag; mixing the wash solution and a separated blood component; separating and then transferring the sedimented wash solution into a wash solution discard bag on the rotor. The separated blood component may be washed a plurality of times. A disposable set of tube-connected bags comprises a primary bag, initially containing whole blood, connected to at component bags for receiving plasma or platelets and also connected to a wash solution bag and a wash solution discard bag. The disposable set may further comprise a red blood cell collection bag connected through a filter.
