Plasma Separation Apparatus, Method and System

摘要

A blood fractionating apparatus that enables aseptic fractionation and storing of fractionated blood components, comprises a centrifuge tube including three chambers separated by constricted sealable passages, an open operative upper end chamber, a closed operative lower end chamber and a middle chamber defined between the upper end chamber and the lower end chamber and connected by means of the sealable passages. A stopper with a flapper valve is provided at the opening of the upper end chamber to control flow of fluid to and from the chambers. This apparatus enables separating the chambers to obtain a hermetically sealed operative lower chamber containing the corpuscle component and a hermetically sealed middle chamber containing the plasma component that can be stored at ambient temperature.
