Abstract

A lancet magazine for use in a lancing aid is described comprising a plurality of lancets each having a lancet body at the proximal end of the lancet and a lancet tip at the distal end of the lancet, where the proximal end of the lancet points in the direction of the proximal end of the housing of the lancet magazine and the distal end of the lancet is aligned in the direction of the distal end of the housing and the lancets in the unused state are completely surrounded by the housing. Furthermore, an extension unit is movably connected to the housing in such a manner that the housing can be extended by movement of the extension unit in the direction of the distal end of the housing such that the lancet is prevented from emerging from the lancet magazine.
