Production of dialysis concentrate from a highly densified concentrate prestage and example of an apparatus for use at the place of dialysis

Abstract

In contrast to the prior art, the essential components of dialyzing liquids are not provided as a dry concentrate or as a genuine solution at the place of dialysis, but as a suspension of undissolved or incompletely dissolved substances, preferably sodium chloride, optionally sodium acetate, in a solution of the remaining components. The suspension is prepared, stored, transported and used in a form designated as an acid cartridge or acetate cartridge, respectively. At the place of dialysis a liquid dialysis concentrate is prepared from the suspension by means of an apparatus, which is here suggested, and can be processed into dialyzing liquid with the existing dosing and safety systems of commercially available dialyzers. The prestage of a dialysis concentrate, which is described in this invention as a suspension, constitutes the supply form with the highest substance density for the components of acid and acetate-containing dialyzing liquids. The cost-saving effects and advantages that can be achieved during transportation, storage and handling are achieved without lowering the standards for the patients' safety as are customary in the use of a conventional liquid concentrate.
