ENHANCED YIELD PLATELET COLLECTION SYSTEMS AND METHODS

摘要

2124818 9408687 PCTABS00032 Systems and methods for separating a suspension of plasma and platelets from whole blood rotate a chamber (58) about an axis (62) to create within the chamber (58) a low-G zone radially close to the axis (62) and a high-G zone (66) spaced radially further from the axis (62) than the low-G zone (64). The systems and methods introduce whole blood into an inlet region (68) of the chamber (58) to initiate separation of red blood cells toward the high-G zone (66) of the inlet region (68). This creates a strong flow of plasma that moves radially toward the low-G zone (64) of the inlet region (68) and elutes platelets into suspension with it. The systems and methods direct the radial flow of plasma and eluted platelets within the inlet region (68) to a port (72) in the inlet region (68) for transport out of the chamber (58).
