  • Patent number: 8409127
    Abstract: A method for emptying a blood tubing set of a blood treatment device that includes an extracorporeal blood circuit with a membrane filter includes supplying air or gas to the blood tubing set to displace liquid therein. The blood tubing set includes arterial and venous patient blood tubes in communication with a first chamber of the membrane filter. The device also includes a substituate line which opens into the arterial blood tube and/or into the venous blood tube, and a substituate pump. To empty the blood tubing set, the arterial blood tube and the venous blood tube are connected to one another to provide a circuit that includes the membrane filter, the arterial blood tube, and the venous blood tube. The substituate line is disconnected, and the air or gas is pumped into the blood tubing set so as to displace liquid into a second chamber of the membrane filter.

  • Publication number: 20130026098
    Abstract: A device and method for monitoring the connection of a blood treatment unit to a fluid system of an extracorporeal blood treatment apparatus are described, in which the blood treatment unit includes an inlet and an outlet for connection to the fluid system and the fluid system includes a line system with a first line segment connected to the inlet and a second line segment connected to the outlet. An extracorporeal blood treatment apparatus includes a device for monitoring the connection of the blood treatment unit to the fluid system. The device and method for monitoring the connection of the blood treatment unit to the fluid system is based on measurement of pressure in the fluid system of the blood treatment apparatus. Solely on the basis of the pressure measurement, it is ascertained whether the connection of the blood treatment unit to the fluid system is correct or incorrect.
