Patent ID: 7883725

Claim:
A kit for preparing a dialysis solution comprising: (a) a container of a dry base concentrate comprising a citrate, a bicarbonate and a salt, wherein a sodium contribution of the dry base concentrate to the dialysate ranges from 100 to 150 mEq/L and a ratio of bicarbonate (mEq/L) to citrate (mEq/L) in the dry base concentrate ranges from 50:1 to 15:8; and (b) a container of an acid concentrate comprising an acid selected from the group consisting of acetic acid, citric acid and lactic acid, wherein a sodium contribution of the acid concentrate to the dialysate ranges from 10 to 20 mEq/L, wherein (i) the combination of the sodium contributions of the dry base concentrate and the acid concentrate to the dialysate ranges from 125 to 150 mEq/L, and (ii) the addition of base concentrate and acid concentrate to a prescribed volume of water produces a final volume of a dialysis solution.
