    摘要: Systems and methods of controlling fouling during a filtration procedure are described. A plasmapheresis method includes accepting a selection of a plasma flow rate and predicting an estimated procedure end time based at least partially on a plasma collection target volume. The method also includes flowing blood past a membrane and changing a plasma flow rate until the selected plasma flow rate through the membrane is achieved. The method also includes determining an acceptable rate of pressure change with time for respective times to the estimated procedure end time, the acceptable fouling rate limit being associated with a system pressure and adjusting the plasma flow rate based on the determined acceptable rate of pressure change with time.

    摘要: A system and method are provided, including an integrated single-use kit, for processing whole blood to produce platelet rich plasma. A two stage spinning membrane separator, has a first stage for receiving whole blood and separating substantially all red blood cells from plasma and platelets, and a second stage for further separating platelet rich plasma from plasma. A first waste container is in fluid communication with the first stage of the separator for receiving separated red blood cells, while a second waste container is in fluid communication with the second stage of the separator for receiving separated plasma. An outlet line is in fluid communication with the second stage of the separator for receiving platelet rich plasma, and a reinfusion container is removably connected to the outlet line for receiving platelet rich plasma from the second stage of the separator.
