The present invention relates to a dialysis machine that is configured to be equipped with an extracorporeal blood system comprising a dialysis solution system that is configured to be equipped with a dialyzer, wherein a mixing region, in particular a mixing chamber, is provided in which the fresh dialysis solution or a component thereof is located in the operation of the dialysis machine, with a concentrate line being in fluid communication with the mixing region, through which concentrate line concentrate can be conducted from a concentrate container into the mixing region, wherein at least two electrically conductive elements are arranged spaced apart from one another in or at the concentrate line or lines; that a measuring device is provided which is electrically connected to the conductive elements and which is configured to measure the conductance or a value correlated therewith between them; and that a control unit is provided which is configured to compare the measured value with a desired value, with a limit value, or with a desired value range.

Dialysis machine and method of operating a dialysis machine

A dialysis machine has a balancing system with a balancing chamber for a volumetrically exact supply and removal of dialysis solution to and from a dialyzer fluidically connected to the balancing system in operation; a water inlet system connected to the balancing system for the supply of fresh dialysis liquid, with the water inlet system having an apparatus for degassing water that is connected to an air separator of the dialysis machine, with a first subsection of the air separator serving as a mixing chamber and being connectable to at least one concentrate source via at least one concentrate line and being in fluid communication with the balancing system via at least one dialysate line, wherein the filling volume of a balancing chamber corresponds to or exceeds the sum of the volume of the mixing chamber and the inner volume of the dialysate line.

Dialysis machine

The present invention relates to a method of monitoring the bicarbonate content and the sodium content of a dialysis solution, wherein the dialysis solution is prepared while adding a bicarbonate component and an acidic sodium component, and wherein the method comprises the following steps:
