Abstract

Methods and systems for collection of blood components, such as plasma, from donors are provided. One method includes the steps of collecting a unit of whole blood froma donor; forcing the collected blood unit through a plasma separator; accumulating the plasma in a container; and returning concentrated cells to the donor. One system includes a disposable blood collection set and a reusable fixture into which the collection set can be mounted. The fixture is operated by a self-contained energy source, requiring no exterior electrical connection or other external source of energy.
