Abstract: An extracorporeal blood purification system with at least one extracorporeal blood purification apparatus, preferably dialysis machine, which is prepared to go through a centrally controlled disinfection process for a blood purification process, as well as with an internal fluid line system which is disinfected at least during the disinfection process by a disinfectant, including an internal or external disinfecting or cleaning case which is at least during the disinfection process via at least one case connection connected to the internal fluid conduit system to receive disinfectant.

Abstract: A machine for extracorporeal blood treatment comprising a machine-side fluid circuit is disclosed. The machine comprises a heat exchanger for heating cold purification fluid freshly supplied on its intake side, for which purpose used still warm purification fluid flows past its opposite discharge side for a heat exchange, and a circulation valve for changing over between a blood purification mode in which the used purification fluid is disposed of in an open fluid circuit through the discharge side of the heat exchanger into a drain and a disinfection mode in which hot disinfectant is circulated in a closed circuit. The circulation valve is connected downstream of the heat exchanger with respect to the discharge side thereof.
