A method of harvesting platelet rich plasma from whole blood, comprising adding an aliquot of blood via the inlet tube of a rotating flexible centrifuge bag comprising inlet and outlet tubes sandwiched between doughnut shaped flexible sheets sealed together at the outer and inner perimeters. The whole blood separates radially into at least a platelet rich plasma fraction and a platelet poor fraction. The distal end of the outlet tube is in flow communication with the platelet rich plasma. The platelet rich plasma fraction is removed from the rotating bag via the outlet tube until a substantial portion of the platelet rich plasma fraction has been removed from the bag. Withdrawal of the platelet rich plasma is terminated when the platelet poor fraction is detected to be near the distal end of the outlet tube. The outlet tube preferably has a bent fitting on its distal end. |
