Abstract
A device and method for inactivating pathogens in therapeutic fluids with sterilizing radiation in a continuous flow arrangement while exhibiting radiation dose uniformity and narrow residence time distribution of the fluid within the device. The device ( ) comprises a radiation permeable cylindrical tube ( ) having a concentric cylindrical rotor ( ) disposed therein, thereby providing a thin gap ( ) therebetween. A top plate ( ) having a fluid outlet ( ) and a bottom plate ( ) having a fluid inlet ( ) seal the cylindrical tube ( ). The inlet ( ) and outlet ( ) are both in fluid communication with the thin gap ( ). A rotor shaft ( ) is disposed axially through the cylindrical rotor ( ) and is connected to a motor ( ). A pump provides fluid flow through the device ( ). A radiation source provides sterilizing radiation to the fluid through the cylindrical tube ( ). As the fluid flows, the motor ( ) drives the rotor ( ) to impart Taylor vortices to the fluid flow, which exchanges the fluid closer to the cylindrical tube ( ) with the fluid closer to the rotor ( ).
