20090291819 | BLOOD SEPARATION CHAMBER - A method for centrifugally separating whole blood into red blood cells and a plasma constituent rotates about a rotational axis a separation zone having radially spaced apart walls with a high-G side and a low-G side located closer to the rotational axis than the high-G side. Whole blood enters the rotating separation zone in an entry region to begin separation. Separation is halted by a terminal wall that is circumferentially spaced from the entry region. The whole blood separates into red blood cells toward the high-G side and plasma constituent toward the low-G side. The method directs red blood cells separated in the separation zone in a circumferential flow direction toward the terminal wall. The method directs separated red blood cells from the rotating separation zone through a second path that extends, at least in part, radially beyond the high-G wall. | 11-26-2009 |
