Abstract

A device and method that can be used to produce dialysis liquid for extracorporeal blood treatment. The device includes a main line for supplying water. An acidic and a basic fluid are introduced in specific dosages. The dosages are set by a control and regulation unit as a function of a chemical and/or physical parameter of the water/fluid mixture. The chemical and/or physical parameter is detected by a measuring device arranged at a section of the main conduit situated downstream of the introduction points for the acidic fluid and for the basic fluid. The control and regulation unit controls introduction of the acidic fluid and basic fluid so that only one of the acid and basic fluids is introduced into the main conduit over a predetermined period or a predetermined interval. Delivery and introduction of the basic fluid and acidic fluid take place alternately.
