Blood component processing system, apparatus and method
WO 2003089027 A3
Abstract
A system and method are used in connection with processing of blood components. The processing of blood components may involve centrifugal separation and/or filtering of the blood components. In some examples, at least some blood components are centrifugally separated in a chamber and then filtered via a filter (31) rotating along with a centrifuge rotor (1), wherein the filter is located closer than the chamber to an axis of rotation of the rotor. The filter may include a porous filtration medium configured to filter leukocytes, platelets, and/or red blood cells. Some examples include a pressure sensor sensing pressure of pumped blood components. The sensed pressure may be used in connection with controlling the pumping of the blood products and/or in connection with determining the location of an interface associated with the blood products. Other uses of the sensed pressure are also possible.
