Abstract
A method and a device are disclosed for regulating an ultrafiltration in a dialysis treatment, in which the blood to be ultrafiltered in an extracorporeal blood circulation () flows through a blood chamber () of a dialyzer (), which is subdivided by a semipermeable membrane () into a blood chamber () and a dialysis fluid chamber (), and dialysis fluid in a dialysis fluid circulation () flows through the dialysis fluid chamber () of the dialyzer (). The device has a blood pump () for controlling a blood flow in the extracorporeal blood circulation (), a dialysis fluid pump () for controlling a dialysis fluid flow in the dialysis fluid circulation () upstream or downstream from the dialyzer (), for controlling the dialysis fluid flow upstream of downstream from the dialyzer, a balancing device () for setting up a fluid balance in the dialysis fluid circulation between an inflow () and an outflow () of the dialysis fluid chamber () as a measure of the ultrafiltration, as well as a regulating unit () for regulating the blood pump (), the throttle () and/or the dialysis fluid pump (). The pumps or the throttles () are regulated so that a predetermined ultrafiltration is achieved.
