The invention relates to a removal device of an infusion system, with a holder part and with at least two penetrating parts protruding from the latter by different lengths, of which the shortest protruding penetrating part comprises a liquid channel, and of which the longest protruding penetrating part comprises at least an air channel. All the penetrating parts are arranged adjacent and parallel to one another. They have a shaft with a nominal cross-sectional area. Moreover, the inner cross-sectional area of the liquid channel is at least 60% of the greatest nominal cross-sectional area of the penetrating parts, at least in the region of the shaft. With the present invention, a removal device is developed which permits safe piercing of the stopper and which ensures a substantial volumetric flow rate of the liquid, while maintaining the standard dimensions.
