ABSTRACT:
Apparatus for oxygenating blood or for separating whole blood into a plasma fraction and an enriched plasma-depleted blood fraction comprising at least two contiguous membrane units, each unit consisting of a first membrane layer, a second membrane layer, a first spacer layer and a second spacer layer. The membrane layers and the spacer layers are configured so that only plasma or oxygen passes through the membrane layers from or into whole blood. Plasma and plasma-deplected blood or oxygen-depleted gas and oxygenated blood are separately collected while preventing admixture thereof with whole blood.
