A hemodialysis assist device including a normally nonflowing aqueous sorbents slurry medium chamber and at least one blood flowthrough passage separated therefrom by a semipermeable membrane of the flat plate, pleated flat plate, hollow fiber or hemicapillary type. The sorbents medium is in the form of a thixotropic network slurry of fine charcoal powder, fine phosphate ion-binding particles, or both. The sorbent particles are substantially retained in place even during ultrafiltration of excess body fluids across the membrane. This retention is assisted by the addition of a small quantity of fine cellulose-based polymer binder capable of forming an interlocking thixotropic network with the sorbents. The assist device may be used in conjunction with a conventional hemodialyzer to reduce dialysis treatment time, as well as to effectively remove urea. In addition, this blood detoxification device can be used also to treat the problems of hyperphosphatemia and hyperlipidemia.
