ABSTRACT:
An apparatus for treating blood in an extracorporeal circuit for hemodialysis of hemofiltration and a method for withdrawing heat from blood in an extracorporeal circuit wherein blood is brought into contact along a membrane with a treatment solution which has been heated to a temperature in a source making the treatment of fluid available such that the energy balance of the patient is maintained, the temperature of the source being controlled in that the temperature of the blood emerging from the patient is measured, the temperature value obtained is compared with a predetermined temperature value and on determination of a difference between the two values the source temperature is changed.
