The present invention provides a lancet reservoir strip with a plurality of lancets arranged transversely (6), by the transfer of the inserted lancet stored strip in the receiving compartment (5) to the longitudinal direction of the lancet storage strip (5) (5) and the conveying device lancet for conveying (6) sequentially to the puncture position of the houses a lancet lancet storage strip and a lancing drive for converting the piercing movement (6) (5) in said puncturing position about the puncture system for collecting a body fluid sample with a housing compartment for. Puncture system is bent portion of the lancet storage strip (5) in the longitudinal direction of the lancet storage strip (5), and thereby separating a lancet tip of the lancet for puncturing (6) (6a) from the lancet storage strip (5) folding device for (10), characterized.
