Abstract
A device for removal of excess water from blood is formed by having a plurality of solution chambers and a plurality of blood chambers arranged alternately, partitioning the adjoining ones of the alternately disposed chambers by insertion of semi-permeable membranes one each along the boundaries thereof and having a sorbent retained in the form of a bed inside the blood chambers, whereby the blood containing waste material and excess water in consequence of renal insufficiency is freed from such fouling substances by causing the blood to flow through the blood chambers in order for the beds of sorbent to deprive the blood of the waste material through sorption and for the high concentration solutions flowing through the adjoining solution chambers to deprive the blood of the excess water through osmosis effected through the medium of the semi-permeable membranes.
