摘要：
Systems and methods for resuspending cellular-rich concentrates of blood are disclosed. Systems include first compartment (24) including a blood inlet port (40) and a plasma-rich platelets (PRP) collection port (38) and a red blood cell collection port (42), and second compartment (26) including a platelet-poor plasma (PPP) collection port (44) and a leukocyte-depleted PRP (LDPRP) inlet port (46), and a separation element (14). In resuspension mode, a volume of retained PPP is returned through the PPP collection port (44) into the second compartment (26) to mix with and resuspend leukocyte-depleted platelet concentrate (LDPC) in the second compartment (26). During the resuspension period, a rotor (28) slowly oscillates the second compartment (26) first in one rotational direction and then in an opposite rotational direction. The oscillation creates variable agitation forces that aid the mixing and resuspension process within the second compartment (26).
