摘要：
A blood tube system for extracorporeal uses, such as dialysis devices, wherein an arterial expansion chamber including a lower region for receiving blood, in which a blood inlet channel terminates, and from which a blood outlet channel extends, and an upper region for receiving air, where a venting channel provided with a venting valve extends from the upper region. The blood tube system includes a central region of the expansion chamber which has considerably reduced cross-sectional dimensions, the blood level being adjustable by means of the venting valve in such a manner that blood/air contact takes place in the central region. The amounts of heparin and EPO needed for a dialysis treatment can thereby be reduced.
