The invention refers to a puncturing device for generating a puncturing woun d by means of a replaceable lancet (10) that comprises a coupling element (4) for transmitting a torque, whereby the puncturing device comprises a lancet driv e (21) which, for a puncture, transmits a torque to an inserted lancet (10) that is couple d to the lancet drive (21) by means of its coupling element (4) such that the inserte d lancet (10) performs a puncturing motion in the form of a rotational motion about a geometric axis. According to the invention the geometric axis extends through the coupling element (4). The invention also refers to a lancet supply ribbon comprising lancets (10) for such device and lancets (2) comprising a lancet body (2) having a lancet tip (3), whereby the lancet body (2), for coupling to a lancet drive (21) of a puncturing device (20), comprises a coupling element (4) by means of which the lancet (10) can be made to perform a rotational motion and has a test field (5) for assaying a body fluid sample to which a body fluid sample can be supplied only after the lancet tip (3) has been pulled out of a puncturing wound that has been generated. |
