DIALYSIS MACHINE CALIBRATION

摘要

The invention covers a cartridge for use in a hemodialysis machine, the cartridge comprising a dialysate flow path including a dialyzer, the dialysate flow path for delivering a flow of dialysate through the dialyzer; a mixing pump defining a chamber having volume variable between a maximum volume and a minimum volume for receiving a predetermined volume of a first dialysate solution base, second dialysate solution base, and a volume of water; a first dialysate solution base supply conduit having a first positive displacement pump having a first inlet valve and a first outlet valve associated therewith; a second dialysate solution base supply conduit having a second positive displacement pump having a second inlet valve and a second outlet valve associated therewith; a first and second fluid conduit associated joining respective first and second positive displacement pumps with the mixing pump; and a third fluid conduit for connecting the mixing pump outlet to a dialyzer filter inlet.
