20100179467 | DEVICE FOR CONTROLLING A SYSTEM FOR TRANSPORTING BLOOD, AND METHOD FOR TRANSPORTING BLOOD IN A BLOOD LINE OF AN EXTRACORPOREAL BLOOD CIRCUIT OF AN EXTRACORPOREAL BLOOD TREATMENT DEVICE - The present invention relates to a device for controlling a system for transporting blood, and a method for transporting blood in a blood line of an extracorporeal blood circuit of an extracorporeal blood treatment system. The present invention also relates to an extracorporeal blood treatment device comprising such a system for transporting blood. The method and device according to the present invention are based on the fact that a defined threshold value for the pressure in the blood line should not be exceeded. The system for transporting blood is controlled in such a way the blood in the blood line is transported in a pre-determined volume flow as long as the pressure in the blood line is below the pre-determined threshold value. When the pressure in the blood line reaches the pre-defined threshold value, however, the system for transporting blood is controlled such that a pressure value corresponding to the threshold value is set when the blood is transported in the blood line. As a result, when the threshold value for the pressure is reached, a regulation of the volume flow is replaced by a regulation of the pressure in the blood line. | 07-15-2010 |
