Abstract
Platelets are collected from blood by delivering blood from a blood source to a centrifugal separator and operating the separator to separate plasma from the blood. The separated plasma is collected in a plasma collecting bag. After a predetermined amount of plasma has been collected in the bag, the plasma is circulated between the bag and the separator. That procedure is repeated at least once to build-up the amount of collected blood. Then platelets are collected by delivering additional blood to the separator and circulating plasma between the separator and the plasma collecting bag at an accelerating circulation rate while rotating the rotor to remove platelets from the separator. The platelets are collected in a platelet collecting bag. Then, blood remaining in the separator is returned to the blood source.
