Abstract:
1. A bag set for use in a conventional centrifuge characterized by a plurality of cups radially disposed about a non-bag-supporting center, comprising, in combination: a centrifuge bag having a distinct inlet for receiving blood and a distinct outlet leading to the first and second bags, all said bags disposed in one cup, whereby said inlet and said outlet are located at opposite ends of said centrifuge bag; supply lines leading from said centrifuge bag to said first and second bags; a three-way metering valve operatively interposed between said outlet and said supply lines, said valve controlled by a motor during a centrifugation cycle to admit blood fractions to said first and second bags, whereby red blood cells are admitted to said first bag while under centrifugation and white blood cells are admitted to said second bag also while under centrifugation, producing a red blood cell bag and a white blood cell bag; a holder for said bag set which ensconces said centrifuge bag and said red and white blood cell bags, said valve in said bag set and communicating with said holder and operatively coupled to said motor located on said holder, said holder adapted to fit into one cup of the conventional centrifuge; and a sensor in said holder, said sensor monitoring a transition from red to white blood cells, whereupon said valve diverts flow of blood cells from said red blood cell bag to said white blood cell bag via said motor.
