Abstract
A single housing includes a diluent inlet, a solution outlet, and a plurality of discrete reagent beds comprising at least one reagent in dry form, wherein the reagent is present in the discrete reagent bed in a proportion sufficient for production of a complete hemodialysate solution.
Claims26
A device for delivering dialysate solution from a single housing, comprising:
- a diluent inlet and a solution outlet, defining a fluid flow path therethrough;
- at least two discrete reagent beds within the housing along the fluid flow path comprising dry reagent in amounts and proportions sufficient for production of a complete dialysis solution, wherein one bed comprises a calcium salt and another bed comprises a bicarbonate;
- and
- at least one compression component positioned to exert pressure on the at least two discrete reagent beds.

A system for providing hemodialysis solution, comprising:
- a water purification pack;
- and
- a dry reagent module configured to connect downstream of the water purification pack, wherein said reagent module comprises a housing, a diluent inlet, a solution outlet, at least two separate reagent beds within the housing along a fluid flow path comprising dry reagent in amounts and proportions sufficient for production of a complete hemodialysis solution, wherein one bed comprises calcium chloride and another bed comprises sodium bicarbonate, and at least one compression component positioned to exert pressure on the at least two separate reagent beds.
A device for storing and delivering dry reagents for medical fluids, comprising:
- a single housing comprising a diluent inlet and a solution outlet, defining a fluid flow path therethrough;
- at least two discrete reagent beds within the housing along the fluid flow path, wherein one bed comprises calcium chloride and other bed comprises sodium bicarbonate, and wherein the other bed is free of calcium chloride prior to use of the device;
- and
- the housing containing at least one compression component positioned to exert pressure on the at least two discrete reagent beds.
