1. A puncturing device comprising:

  • a band-shaped lancet carrier carrying a plurality of lancets;

    a transport mechanism for positioning the lancets sequentially in a launch position by moving the band-shaped lancet carrier;

    a lancet drive for accelerating one of the lancets from the launch position for a puncturing movement, the lancet drive comprising an energy storage for providing energy for the acceleration of the lancet, wherein the energy storage includes a drive spring which is coupled to the transport mechanism in such a way that transportation of one of the lancets to the launch position causes a tensioning of the drive spring;

    a trigger element for triggering the lancet drive to release energy from the energy storage to accelerate the lancet for the puncturing movement; and

    a housing which comprises at least two housing parts and encloses the band-shaped lancet carrier and the lancet drive, the housing having an opening against which a body part is pressed for puncturing by the lancet positioned in the launch position, whereinthe transport mechanism comprises at least one part which is arranged in a fixed position with respect to the housing, and whereinthe puncturing device is adapted for disposable use in that an irreversible connection between the housing parts is formed and the band-shaped lancet carrier is irremovably enclosed within the housing parts upon assembly of the puncturing device.
