Devices and methods for transporting blood in the blood conduit containing the extracorporeal blood circuit in an extracorporeal blood treatment device for controlling the system for transporting blood

摘要

(61), and a device for controlling a system for transporting the blood (20), the present invention relates to a method for transporting blood in the blood tubing in the extracorporeal blood circuit of an extracorporeal blood treatment system. Furthermore, with a system for transporting blood as described above, the present invention relates to extracorporeal blood treatment device. It is based on the fact that the device and method according to the present invention is that, should not be exceeded is defined threshold regarding pressure (9) in the blood tubing. As long as the pressure of blood pipe (9) in is below a predetermined threshold, the blood in the blood pipe to be transported in a volume a predetermined flow rate, a system for transporting blood (20) is controlled . However, when the blood pressure piping reaches a predetermined threshold, the system for transporting blood, when the blood is carried in the blood pipe, the pressure value corresponding to the threshold to be set and controlled. As a result, when the threshold value for the pressure is achieved, the adjustment of the volume flow rate is replaced by the adjustment of the pressure in the blood piping. [Selection Figure Figure 3
