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.
