Abstract

See full text

A fluid processing device includes a controller, a centrifuge configured to receive and rotate a continuous-flow centrifuge chamber, a pump system, an optical detection assembly, and a pressure sensor. The controller executes a priming procedure in which a priming fluid is conveyed into the centrifuge chamber while the chamber is being rotated by the centrifuge, which moves air out of the chamber via a low-g outlet conduit. Upon detecting priming fluid exiting the centrifuge chamber via the low-g outlet conduit, the chamber is rotated at a higher rate to attempt to move any remaining air out of the chamber via the low-g outlet conduit. The controller then determines, based on signals from the optical detection assembly and pressure sensor, whether there is any air remaining in the centrifuge chamber. If so, the rotational rate is alternately decreased and increased until all the air has been cleared from the centrifuge chamber.
