Enhanced yield blood processing systems and methods establishing controlled vortex flow conditions

摘要

Blood processing systems and methods create dynamic vortex flow conditions within the processing chamber by conveying blood into a separation path that extends circumferentially about the rotational axis along an entry path that extends generally parallel to the rotational axis. The vortex flow conditions perfuse blood into the separation path for separation into component parts. The systems and methods confine the vortex flow pattern along the entry path by reducing the radial width of the entry path.
