摘要：
A method and a device are disclosed for controlling or regulating an ultrafiltration in a dialysis treatment in which blood to be ultrafiltered flows in an extracorporeal blood circulation (109) through a blood chamber (110) of a dialyzer (113), which is divided by a semipermeable membrane (111) into the blood chamber (110) and a dialysis fluid chamber (108), and dialysis fluid in a dialysis fluid circulation (109) flows through the dialysis fluid chamber (108) of the dialyzer (113). The device has a blood pump (115) for creating a blood flow in the extracorporeal blood circulation (112), a dialysis fluid pump (107) for creating a dialysis fluid flow in the dialysis fluid circulation (109), a balancing device (104) for setting up a fluid balance in the dialysis fluid circulation between an inflow (106) and an outflow (105) of the dialysis fluid chamber (113) as a measure of the ultrafiltration, and a regulating unit (101) for regulating the blood pump (115) and/or the dialysis fluid pump (107). The regulation is performed in such a way that a predetermined ultrafiltration is achieved without any further active control or regulation of the dialysis fluid flow flowing into the dialyzer (113) or flowing out of the dialyzer (113).
