Abstract

A dialysis machine has two hydraulic connectors at the dialysate side to which a respective connection line having a filter coupling is connected for connection to a dialyzer, with the hydraulic connectors being an inflow connector for feeding fresh dialysis liquid to the dialyzer and a backflow connector for draining consumed dialysate from the dialyzer. The dialyzer machine also has two parking positions associated with the respective hydraulic connectors for storing the filter couplings when not in operation, wherein the filter couplings of both hydraulic connectors are equipped with a connection sensor which recognizes a connecting of the filter coupling to a dialyzer and/or that both parking positions are provided with separate covers.
