Method for removing blood from an extracorporeal blood circuit as well as apparatuses

摘要

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.

1. A method for removing blood from an extracorporeal blood circuit and/or a functional device at the end of a blood treatment session, each of said extracorporeal blood circuit and/or functional device being connectable or connected with a blood treatment apparatus for the purpose of blood treatment of a patient, wherein the blood treatment apparatus comprises or is connected with: at least one extracorporeal blood circuit with a line having interior portions, wherein the extracorporeal blood circuit comprises at least one arterial line section and at least one venous line section, a first section of the arterial line section and a second section of the venous line section being connected or configured to be connected; and, at least one blood pump for conveying blood within the line interior portions of the extracorporeal blood circuit; wherein the method comprises the steps of: operating the blood pump in a second conveying direction which is opposite to a first conveying direction of the blood pump which is customary during the blood treatment; disconnecting an arterial needle connection of the arterial line section of the extracorporeal blood circuit from the patient; and connecting the arterial needle connection of the extracorporeal blood circuit with a venous addition point of the venous line section of the extracorporeal blood circuit.
