1322143 Preparing dialysis liquid; proportioning mixture constituents RHONE-POULENC SA 6 Jan 1972 [6 Jan 1971] 586/72 Headings B1C and B1X A dialysis liquid monitoring and generating assembly for supplying dialysis liquid to at least one haemodialyser comprises a vessel (6) for metering water and a vessel (7) for metering dialysis liquid concentrate, each of said vessels having means for detecting the levels of the respective liquid therein, a mixing tank (8), and a storage tank (9), flexible pipelines connecting the water metering vessel and the dialysis liquid concentrate metering vessel to a source of water and a source of dialysis liquid concentrate respectively, flexible pipelines connecting said two metering vessels to the mixing tank, and a flexible pipeline connecting said mixing tank to the storage tank, the relative positions of said vessels and said tanks being such that the liquids flow from the vessels to the mixing tank and thence to the storage tank by gravity, a valve between each of said metering vessels and its respective source, and means for simultaneously pinching both of said flexible pipelines at locations between said vessels and their respective sources, means for simultaneously pinching both of said flexible pipelines at locations between said vessels and the mixing tank, and means for pinching said pipeline between the mixing tank and the storage tank, said means for pinching the flexible pipelines being interconnected and actuated by a single motor. The pinching of the pipelines in accordance with a cyclic programme may be brought about by means of suitable cams on the shaft of an electric motor. The apparatus may also include a heating means (19) to heat the dialysis liquid before supplying it to the dialyser (23), and valves to convert part of the apparatus including the heating means but not the dialysis into a closed circuit in which, liquid can be heated to a temperature high enough to effect sterilisation of the apparatus.
