    • A device for separating plasma from whole blood is provided having an evacuated primary collection chamber capable of fluid communication through a porous filter to an evacuated secondary collection chamber. An agglutinating agent is provided within the primary collection chamber so as to aggregate blood cells within a whole blood sample. The porous filter has a pore size which is small enough to capture the aggregated blood cells therein, yet large enough to permit plasma to transfer therethrough under pressures associated with conventional evacuated blood collection tubes. The primary and secondary collection chambers may be provided in separate containers or tubes, with transfer occurring therebetween through a transfer device including the porous filter therein.
    • 提供了一种用于从全血中分离血浆的装置,其具有能够通过多孔过滤器与抽空的二次收集室流体连通的抽真空的主收集室。 在主收集室内提供凝集剂,以便聚集全血样品中的血细胞。 多孔过滤器具有足够小的孔径以捕获其中的聚集血细胞,但足够大以允许血浆在与常规抽空采血管相关联的压力下转运。 初级和次级收集室可以设置在分开的容器或管中,其中通过包括其中的多孔过滤器的转移装置在其间进行转移。
