ABSTRACT:
A multicomponent fluid separation and irradiation system is described containing a centrifuge drum and a source of radiant energy located within the drum. In a first embodiment a disposable rigid separation/irradiation chamber is provided with a cylindrical outer compartment located within the drum and opposing the radiant energy source. Whole blood is supplied to the chamber through a dynamic seal located at the center of the chamber. As the chamber is rotated, blood is separated so that energy from the source passes through the inner wall of the chamber and the separated plasma layer to irradiate the buffy coat layer. In a second embodiment, one or both of the walls of the outer compartment of the chamber are flexible so that the chamber will expand as blood is pumped in and will collapse as blood is pumped out.
