Abstract

See full text

A method and apparatus for the treatment of blood are disclosed allowing for the determination of an internal convection in a blood purification device e.g. in the form of a dialyzer. The internal convection in the purification device can be determined on the basis of pressure differences in the purification device. The blood purification may be, for instance, a hemodialysis or a hemodiafiltration. Pressure sensors serve for measuring the pressures of the blood at the input and/or output of the purification device as well as optionally for detecting the pressure of a cleaning fluid or dialysis fluid at the input and/or output of the purification device.
