Abstract
A blood treatment apparatus comprises a dialysis liquid system having devices for mixing a dialysis liquid from, or with, at least one first concentrate from a concentrate supply system. The blood treatment apparatus comprises a first connecting line arranged upstream of the dialysis liquid system having a first connector for a fluidic connection of a section of the dialysis liquid system to the concentrate supply system. The blood treatment apparatus further comprises a first valve, which is provided downstream of the first connector in or on the first connecting line. The blood treatment apparatus further comprises a control device or closed-loop control device.

A blood treatment apparatus comprising:
- a dialysis liquid system having devices for mixing a dialysis liquid from, or with, at least one first concentrate from a concentrate supply system;
- a first connecting line arranged upstream of the dialysis liquid system and having a first connector for fluidically connecting a section of the dialysis liquid system to the concentrate supply system;
- and
- a first valve provided downstream of the first connector in or on the first connecting line.
A control device or closed-loop control device configured to prompt the following method steps:
- a) building up or setting, using a conveying device of a dialysis liquid system, an overpressure or underpressure in a section of the dialysis liquid system as a first test pressure;
- and
- b) measuring, in a first pressure measurement, a pressure prevailing in the section by using a third pressure measuring device of the dialysis liquid system, or measuring a pressure prevailing in a first connecting line by using a first pressure measuring device of the dialysis liquid system and/or measuring a pressure prevailing in a second connecting line by using a second pressure measuring device of the dialysis liquid system.
