Abstract
A tube system comprising a blood inlet line with an arterial patient connection and a blood return line with a venous patient connection, where a rinsing liquid inlet line branches off from the blood inlet line downstream from the arterial patient connection, and a rinsing liquid return line branches off from the blood return line upstream from the venous patient connection is filled while maintaining sterility in that rinsing liquid is pumped from a rinsing liquid container through the rinsing liquid inlet line, the blood inlet line, the blood return line and the rinsing liquid return line, establishing a liquid connection between the rinsing liquid inlet line and return line. The venous patient connection is sealed liquid-tight with a venous safety cap, and the arterial patient connection is sealed liquid-tight with an arterial safety cap. The safety caps are removed from the patient connections for connecting the tube system to the patient.
