Abstract

The present invention relates to a method for removing blood from an extracorporeal blood circuit and/or a functional device, each connectable or connected with a blood treatment apparatus for the purpose of blood treatment of a patient. The blood treatment apparatus of the method comprises or is connected with at least one extracorporeal blood circuit with a line having interior portions, the extracorporeal blood circuit comprising at least one arterial line section and at least one venous line section, wherein a first section of the arterial line section is configured to be connected with a second section of the venous line section, and further comprises at least one blood pump for conveying blood within the line interior portions. The method includes the step of operating the blood pump in a second conveying direction which is opposite to a first customary conveying direction. It further relates to corresponding apparatuses.
