Patent ID: 8216264

Claim:
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, wherein the transport mechanism comprises at least one part which is arranged in a fixed position with respect to the housing, and wherein the 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.
