Abstract

1467880 Dialysis apparatus V H HYDEN 5 July 1974 [5 July 1973] 29851/74 Heading B1X [Also in Division C3] Dialysis apparatus, such as an artificial kidney, with selective chemical activity, which includes a semipermeable dialysis membrane forming a partition between the liquid to be dialysed and a dialysate, the dialysis membrane being selected to permit the passage of substances with molecular weights of at least 2500, a first surface of the dialysis membrane facing the dialysed liquid, a second surface facing the dialysate, at least one of its surface being coated with at least one selectively chemically active substance insolubilised on the surface and at least one selectively acting adsorbent being provided in the circuit of the dialysate. The chemically active substance may be an enzyme or other protein, or an antibiotic. The dialysis membrane may be in the form of a flattened tube, with a spacing member having an open structure carrying an adsorbent and the membrane and spacing member wound helically together. The adsorbent may consist of pre-conditioned zirconium phosphate and/or zirconium oxide, optionally in combination with active carbon.
