ABSTRACT:
An improved conductivity based servo-proportioning system for hemodialysis machines. The servo-proportioning system calculates the actual conductivity contributions of the individual chemical components of the concentrate being utilized, to determine the conductivity set points. If an Acidified and Bicarb operation is being performed, then the servo-proportioning system calculates a conductivity set point at both an intermediate and final stage of the servo-proportioning system. If only acetate is being performed, then only the acetate individual chemical components are calculated. If the Na and/or Bicarb concentrations are to be varied, then the conductivity is calculated for the changed Na and/or Bicarb concentrations.
