摘要：
The invention relates to a method and a device for controlling an extracorporeal blood treatment apparatus, which can be operated in particular as a haemodialysis apparatus, a haemofiltration e apparatus or a haemodiafiltration apparatus. For the control of the pumps, the method according to the invention and the device according to the invention make provision, apart from balancing the fluids as a function of the weights of the containers, for the measurement of the weight reduction or weight increase of at least one of the containers in the time interval in which the pump assigned to the respective container performs a preset number of revolutions or pump strokes. For example, the change in the weight of the container for a half or one pump revolution can be determined. The delivery rate of the respective pump is ascertained from the measured weight reduction or weight increase in the specific time interval. The ascertainment of the weight reduction or increase per unit of time permits the precise determination of the actual delivery rate of one or more pumps. The actual delivery rates of all the pumps are preferably monitored.
