The invention relates to a removal device (31) of an infusion system (10) having a mounting part (32) and at least two penetrating parts (41, 51) having different lengths and protruding therefrom, wherein the shortest protruding penetrating part (41) comprises a fluid channel (46) and wherein the longest protruding penetrating part (51) comprises at least one air channel (61). To this end, all penetrating parts are disposed adjacent and parallel to each other. They have a shaft (42, 52) having a nominal cross-sectional area. The inner cross-sectional area of the fluid channel is further at least 60% of the largest nominal cross-sectional area of the penetrating parts, at least in the region of the shaft. According to the present invention, a removal device is developed wherein a secure penetration of the stopper and a larger volume flow of fluid is achieved while maintaining standard dimensions.
