ABSTRACT:
Fluid separation method and apparatus for simultaneously carrying out dialysis and ultrafiltration and exactly controlling the ultrafiltration rate is disclosed. The method and apparatus is concerned with a dialysis system comprising the combination of a fluid separating device; one or more units for dialysate each unit, each unit comprising a pair of dialysate chambers separated by at least one partition which is movable or transformable while keeping the over-all volume of a pair of dialysate chambers constant; a variable speed dialysate feed pump; a variable speed dialysate discharge pump; and other devices e.g. monitoring devices.
Fresh dialysate is fed from one of the dialysate chambers into the dialysate inlet of the fluid separating device; separation treatment is carried out through the semi-permeable membrane of the fluid separating device; waste dialysate is discharged from the dialysate outlet of the fluid separating device into the dialysate chamber and the over-all volume of this closed circuit is maintained constant. The controlled ultrafiltrate is exactly discharged from the closed circuit by an ultrafiltration pump; and a continuous operation is carried out in a plurality of units for exchanging dialysate alternately.
