Abstract

It is disclosed a circuit for extracorporeal blood treatment in which a flow-inverting device is interposed between a blood treatment unit and a blood pump placed on an artery branch connected with a vascular access of a patient. The flow-inverting device allows the blood flow within the filtering unit to be kept unchanged even following an inverted circulation in the patient-side artery and vein branches controlled by the blood pump.
