Abstract
A dialysis acid precursor assembly including: a dry dialysis acid precursor composition including sodium chloride, a dry acid and a magnesium chloride 4.5-hydrate (MgCl2.4.5H2O), a calcium salt and at least one of a potassium salt, calcium salt and an anhydrous glucose, and a moisture-resistant container having a water vapor transmission rate less than 0.2 g/m2/d at 38° C./90% RH, wherein the dry dialysis acid precursor composition is sealed in the container.
Claims14
A dialysis acid precursor composition for use during preparation of a dialysis acid concentrate solution and for mixing with water and a bicarbonate containing concentrate into a ready-for-use dialysis solution, wherein said dialysis acid precursor composition consists of powder components comprising sodium chloride, at least one dry acid and at least one magnesium salt, said at least one magnesium salt is present as magnesium chloride 4.5-hydrate (MgCl2.4.5H2O) and wherein said dialysis acid precursor composition is sealed in a moisture-resistant container with a water vapor transmission rate less than 0.2 g/m2/d at 38° C./90% RH.
A method of providing a dialysis acid concentrate solution for dilution with water and a bicarbonate containing concentrate to produce a ready-for-use dialysis solution, comprising:
- (a) providing a dialysis precursor composition comprising sodium chloride, at least one dry acid, and at least one magnesium salt, wherein said at least one magnesium salt is present as magnesium chloride 4.5-hydrate (MgCl2.4.5H2O),
- (b) providing said dialysis precursor composition in a sealed, moisture-resistant container with a water vapor transmission rate less than 0.2 g/m2/d at 38° C./90% RH, and
- (c) adding a prescribed volume of water to said dialysis precursor composition in said container and mixing thereof, thereby providing said dialysis acid concentrate as a solution.
A dialysis acid precursor assembly comprising:
- a dry dialysis acid precursor composition comprising sodium chloride, a dry acid and a magnesium chloride 4.5-hydrate (MgCl2.4.5H2O), and
- a moisture-resistant container having a water vapor transmission rate less than 0.2 g/m2/d at 38° C./90% RH, wherein the dry dialysis acid precursor composition is sealed in the container.
