A perfusion liquid is suctioned from a perfusion liquid reservoir (16) through the automatic two-way valve (4) by drawing a syringe (5) serving as the perfusion liquid displacement device. For this purpose, the connection from the syringe (5) to the cannula (14) is closed by the two-way valve (4). The two-way valve (4) closes the connection to the perfusion liquid reservoir due to the pressure increase during the insertion of the syringe plunger and opens the connection from the syringe (5) to the cannula (14). A pressure relief valve (7) is attached at the T piece (6), exposing a discharge line (8) in case a threshold pressure is exceeded. A check valve (11) is attached at the extension of the cannula (14), preventing the backflow from the cannula (14) into the remaining system.
