ABSTRACT:
A dialysis apparatus for purifying a fluid substance, particularly blood, containing contaminants which are diffused through semi-permeable diaphragms into a purification liquid. The apparatus comprises first plates having planar surfaces respectively disposed between opposing second plates provided with bosses on the surfaces facing the planar surfaces of the first plates. A plurality of these plates is alternately assembled into a stack with a diaphragm arranged between the opposite surfaces of the first and second plates. Portions of the clamped diaphragm are forced between the bosses of the second plates a predetermined distance to define two channels for the circulation of the two fluids.
