Abstract

See full text

A blood processing assembly includes a separation element for separating blood from a source into a first component and a second component. The assembly also includes a fluid path that conveys blood between the source and the separation element. The fluid path includes one or more in-line cassettes that serve in association with peristaltic pumps to centralize pumping and valving functions of the system. The cassettes also serve to segregate the flow paths of the blood components from each other.
