Abstract

1,146,756. Haemodialysis apparatus. SWEDEN FREEZER MFG. CO. 3 Oct., 1966 [23 Oct., 1965; 15 March, 1966], No. 43995/66. Heading A5R [Also in Divisions B1 and G1] Dialysis apparatus for use as an artificial kidney comprises three rigid plates 15, 16, 17 separated by two pairs of membranes 14, 14', there being an elastomeric gasket 22 surrounding the rim of the centre plate 16 and providing a seal against the membranes when the plates and membranes are clamped together. As shown in an exploded view, each pair of membranes 14, 14' is in the form of an envelope of plastics material through which the blood is passed and the rigid polypropylene plates 15, 16, 17 are provided in their surfaces adjacent the membranes with longitudinal and transverse grooves 20, 30, 20', 30' along which the dialysate solution is caused to flow. The rigid plates and membranes are clamped together between frames (50, 51) by adjustable toggle clamps (52) (see Figures 1, 2, not shown) and the assembly is then supported on a stand (11). Channel strips 41 at each end of the membrane envelopes facilitate handling during their replacement and bores and passages 33, 33', 37, 37', 40, 40' lead the flow of dialysate solution from an inlet (18) to the assembly, through the grooves 20, 30, 20', 30', and to an outlet (19). Suitable sealing (see Figures 5-8, not shown) is provided around the inlet and outlet nozzles to the membrane envelopes. The dialysis apparatus may be used in a system which includes a storage and mixing device of concentrated and diluted dialysis solution (Figures 9, 10, not shown) situated in a convenient remote position, and a bedside unit (Figure 11, not shown) including a reservoir (202) holding dialysis solution at body temperature and connected to the dialysis apparatus (208) and to a pump (214) drawing the solution through the apparatus. The system is controlled using various solenoid- and float-operated valves and includes timing devices used in sterilizing and rinsing the system.
