Abstract
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.
