ABSTRACT:
A method and apparatus of processing biological fluids by adding or removing preservatives or simply removing water comprises providing a bag of semi-permeable membrane which contains the biological fluid and bathing the bag with dialysate having controlled osmolality. The preservative or water can thus be removed or added to the bag directly through the semi-permeable membrane by controlling the osmolality of the dialysate without exposing the biological fluid to contaminants. In the case of whole or components of blood, the blood or blood components can be collected in the bag, processed for preservation, and prepared for use then administered, all in the same bag.
