Abstract
An apparatus for separating and collecting plasma from whole blood includes volume and rate monitoring systems (92, 93) which provide continuous automatic displays of the volume and rate of plasma collected. The systems analyze incremental changes in the collected plasma weight over successive time intervals. The systems continuously display volume and rate measurements, and are not effected by changes in tare weight or a change in the plasma collection container. The apparatus further includes a ratio control system (106) which enables replacement fluid to be added by a replacement fluid pump (52) associated with the apparatus to process plasma-deficient blood at a predetermined ratio relative to the volume of plasma collected in a collection container.
