Abstract

Dialyser comprises a stack of alternate plates and pairs of dialysis membranes providing passages for the dialysate between a plate and an adjacent membrane, and for the liq. to be purified between two membranes. End plates seal the stack. On each face of the intermediate plates and the inwardly-directed faces of the end plates rows of short parallel ribs are provided, sepd. by lines of transverse ribs. The spacing of the first and last rows of ribs from the corresp. adjacent edges of the plate is such that when the plates are turned through 180 degrees relative to neighbouring plates the rows of ribs are staggered in contact by about half the length of the ribs in a row. The ribs provide a large number of points of contact with the membranes, liniting the flow of the liq. to be purified to a film between the membranes. This improves the efficiency of the dialysis. The dialyser may be used for blood dialysis as a disposable unit, and the volume of blood lost by retention in the unit is kept very small.
