Abstract:
1. A blood concentrator comprising: a main housing defining a centrifuge chamber for holding blood during centrifugation, wherein the centrifugation chamber comprises a first port that is adjustably positionable to permit selection of a portion of blood to be extracted after centrifugation; a filter housing connected to the centrifuge chamber, wherein the filter housing is disposed within the centrifugation chamber; and a filter membrane held by the filter housing for the removal of water and low molecular weight components out of an extracted centrifuged portion of the blood for retention and collection of a centrifuged and concentrated blood substance, wherein the filter membrane comprises one or more filter membranes oriented parallel to filter flow direction, such that a filtrate moves through the filter housing while water and low molecular weight components pass through the filter membrane transverse to the filter flow direction.
