  • Patent number: 11931494
    Abstract: The invention relates to a dialysis machine having a fluid system that has an inflow line for providing fresh dialyzing solution to a dialyzer and an outflow line for removing used dialyzing solution from the dialyzer, wherein the fluid system has a balancing system arranged between the inflow and outflow lines to balance the fluid volumes flowing through the lines, and wherein the fluid system has an ultrafiltration line that branches off from the outflow line between the dialyzer and the balancing system and has an ultrafiltration pump to be able to remove a defined volume of used dialyzing solution from the balance, and wherein an additional balancing chamber is provided that is arranged in a section of the inflow line disposed between the balancing system and the dialyzer or in a section of the outflow line disposed between the dialyzer and the branching of the ultrafiltration line.

  • Patent number: 11305043
    Abstract: The present disclosure relates to a method and system for regulating and/or monitoring a heating device for heating a fluid, which has flowed in an in-flow section of a dialysis fluid circuit. The dialysis fluid circuit is part of a blood treatment apparatus, which comprises a container for receiving the fluid and a heating container for heating the fluid. The method encompasses the step of starting a heating process for heating the fluid in the heating container. The fluid is in fluid communication with the container when the filling level of the container reaches a pre-determined filling level value by means of direct or indirect flow from the inlet.
