Abstract
A dialysis machine has at least one filter for the filtration of dialysis liquid and a device for determining calcification of the dialysis machine. The device has one or more sensors configured and arranged to detect either downstream, or upstream and downstream, of the at least one filter an ion concentration or a parameter representative of the ion concentration or of its change of the dialysis liquid, of a solution serving the decalcification or of another measuring solution. The device for determining the calcification of the dialysis machine has an evaluation or calcification unit configured to determine the calcification of the dialysis machine based on the ion concentration or parameter value detected by the sensor or sensors.
