摘要

blood flow reversal device for an extracorporeal blood treatment device and method for determining blood flow reversal during an extracorporeal blood treatment. the present invention relates to a blood flow reversal device for an extracorporeal blood treatment device, which comprises an extracorporeal blood circuit (i), which features an arterial blood line (108a) leading from the patient to a blood treatment unit (204) and a venous blood line (106a) leading from the blood treatment unit to the patient. moreover, the invention relates to an extracorporeal blood treatment device with a blood flow reversal device as well as a method for determining the reversal of blood flow in an extracorporeal blood treatment. the device according to the invention for reversing the blood flow of an extracorporeal blood treatment device has two valve bodies (102, 104) which are rotated in the opposite direction to each other to reverse the blood flow. the device according to the blood flow reversal invention is characterized by a communication equipment (210) for receiving a high frequency electromagnetic field from the reading equipment (270) of the extracorporeal blood treatment device and for generate at least one indicator that characterizes the position of the valve bodies, which can be read by the reading equipment.
