ABSTRACT:
In a hemodialysis unit the container for the reception of the total supply of dialysate is constructed thermoinsulated with respect to the environment. The dialysate need not be heated during the dialysis process and through maintenance of a stable vertical temperature gradient between the fresh dialysate removed from the upper end of the container and the used dialysis fluid returned at the lower end of the container a stable stratification is obtained. Mixing of used and fresh dialysis fluid is thereby avoided. A further development provides for an ultraviolet radiator for the sterilization of the dialysate in a tube arranged centrally in the container, serving for the return of the dialysate. For the control of ultrafiltration, there is an overflow and measurement of the excess amount of liquid on the return line to the container and an adjustment of flow resistance on the return line of at least one of the two flow paths through the dialyzer.
