Abstract
An apparatus, system and process for continuously fractionating blood in which blood from a donor is passed along a semipermeable membrane through which passes a fraction to be collected. Turbulent blood flow is maintained to prevent a filter cake from building up on the membrane surface and thereby prevent the blood fraction from passing therethrough. The system includes the blood fractionator, a collection apparatus, a blood pump and appropriate blood clot filters. The rapid blood fraction production rate and the small size of the device facilitates in situ collection of the blood fraction. Fractionation rates upwards of 30 volume percent of blood flow are possible.
