Abstract

The invention relates to a dialysis machine for treating a body fluid, e.g. blood or plasma, said machine comprising a dialyzer (100), a dialysate supply system (5) having a dialysate supply line (52) connected to the inlet (401) of the dialysate flow-through zone (14), and a dialysate delivery system (510) which is connected to the supply line (52) and which includes at least one pouch (50) for holding dialysate as well as means for pressurizing the pouch (50). The machine also comprises a connection system (450) with a first branch (451) which can be connected to a first dialysate feeding source (40) and which includes a clamp system (C451) for opening/closing the first branch (451), the connection system (450) also having a second branch (452) which can be connected to a second dialysate feeding source (40') and which includes a clamp system (C452) for opening/closing the second branch. The connection system further has a section (455) which communicates with the first branch (451) and the second branch (452) and which can be connected to the dialysate delivery system (510).
