摘要:
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 (109) flows through a blood chamber (110) of a dialyzer (113), which is subdivided by a semipermeable membrane (111) into a 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 controlling a blood flow in the extracorporeal blood circulation (112), a dialysis fluid pump (107) for controlling a dialysis fluid flow in the dialysis fluid circulation (109) upstream or downstream from the dialyzer (113), for controlling the dialysis fluid flow upstream of downstream from the dialyzer, 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, as well as a regulating unit (101) for regulating the blood pump (115), the throttle (117) and/or the dialysis fluid pump (107). The pumps or the throttles (117) are regulated so that a predetermined ultrafiltration is achieved.
