    • 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 (10) comprises a radiation permeable cylindrical tube (12) having a concentric cylindrical rotor (14) disposed therein, thereby providing a thin gap (16) therebetween. A top plate (18) having a fluid outlet (26) and a bottom plate (20) having a fluid inlet (24) seal the cylindrical tube (12). The inlet (24) and outlet (26) are both in fluid communication with the thin gap (16). A rotor shaft (36) is diposed axially through the cylindrical rotor (14) and is connected to a motor (30). A pump provides fluid flow through the device (10). A radiation source provides sterilizing radiation to the fluid through the cylindrical tube (12). As the fluid flows, the motor (30) drives the rotor (14) to impart Taylor vortices to the fluid flow, which exchanges the fluid closer to the cylindrical tube (12) with the fluid closer to the rotor (14).
    • 一种用于灭活存在于治疗性流体病原体在连续流动装置消毒辐射,同时表现出的辐射剂量的均匀性和在装置内的流体的窄停留时间分布的装置和方法。 的装置(10)包括具有设置于其中的同心圆筒状的转子(14),从而提供薄的间隙(16)之间有一个辐射透过的圆柱形管(12)。 顶板(18),其具有一个流体出口(26)和具有流体入口(24)的底板(20),密封该圆柱形管(12)。 所述入口(24)和出口(26)与两个薄间隙(16)流体连通。 转子轴(36)穿过所述圆筒形转子(14)轴向diposed并且被连接到一个马达(30)。 泵提供通过所述装置(10)的流体流动。 辐射源提供通过圆筒形管(12)灭菌辐射到流体。 当流体流动时,马达(30)驱动转子(14),以赋予泰勒旋涡的流体流动,这交换流体更靠近圆柱形管(12)与所述流体更靠近所述转子(14)。
