1-6. (canceled)
An apparatus to produce concentrated blood components, which apparatus comprises:
- a) a separation disc which receives blood through a first conduit, which separation disc rotates to generate centripetal force, thereby separating the blood into two or more blood components according to density;
- b) a control system operably connected to a first pump operably coupled to the first conduit, wherein the control system controls transfer of blood and/or blood components to the separation disc by controlling the pump;
- and,
- c) a concentrator which receives one or more of the blood components from the separation disc through a second conduit, which concentrator comprises at least one ultrafiltration membrane, which membrane comprises a retentate side and a permeate side wherein, during operation of the apparatus, the blood components being contacted to the retentate side of the membrane with a pressure gradient, thereby forcing one or more low molecular weight molecules through the membrane to a permeate side of the membrane and concentrating blood components.
