Abstract:
1. A dialysis system for preparing a citrate dialysate from a base concentrate and an acid concentrate, said system comprising: a conductivity sensor for measuring conductivity of a solution; a dialyzer having a dialysate side and a blood side; and proportioning pumps for metering a base concentrate, an acid concentrate, and water to produce a citrate dialysate, wherein said base concentrate comprises a citrate, bicarbonate and a salt, wherein a sodium contribution of the base concentrate to the dialysate ranges from 100 to 150 mEq/L; wherein said acid concentrate comprises an acid selected from the group consisting of acetic acid, citric acid and lactic acid, wherein (i) a sodium contribution of the acid concentrate to the dialysate ranges from 10 to 20 mEq/L, (ii) the combination of the sodium contributions of the base concentrate and the acid concentrate to the dialysate ranges from 125 to 150 mEq/L; and wherein the system circulates said dialysate to said dialysate side of said dialyzer if conductivity of said dialysate ranges from between about 12.5 and about 15.7 mS/cm and does not circulate the dialysate if said conductivity falls outside of said conductivity range.
