Abstract

Abstract 1470428 Blood dialysis apparatus TRIOFLO RESEARCH LABORATORIES Ltd 4 Sept 1974 [10 Sept 1973 16 April 1974] 38703/ 74 Heading B1X Blood dialysis apparatus comprises at least a pair of board means 3, 4, 5, a blood flow path 25 (28) communicating with the blood supply of a patient and including a segment in which the blood when flowing in the path is subject to dialysis, a pair of semi-permeable filtration media 20, 21 (22, 23) defining the segment, a first dialysate flow path 24 (27) including a hypertanic dialysate solution and having a dialysis segment defined by one filtration medium and one board means, a second dialysate flow path 26 (29) is dependent of and separate from the first, including a hypotanic dialysate solution and having a dialysis segment defined by the other filtration medium and the other board means. The hypertanic and hypotanic dialysate solutions may each comprise Na<SP>+</SP>, Ca<SP>++</SP>, K<SP>+</SP>, Cl<SP>-</SP>, HCO 3 <SP>-</SP> where the concentration of the ions is greater in the hypertanic solution. The hypertanic dialysate solution may also comprise Mg<SP>++</SP>, citrate<SP>-</SP>, lactate<SP>-</SP>, acetate<SP>-</SP>.
