Disposable puncturing device and reusable handling device for a puncturing device
First Claim
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.

Abstract
A puncturing device includes 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 a puncturing movement, the lancet drive comprising an energy storage, a trigger element, and a housing which includes 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, wherein the transport mechanism includes at least one part arranged in a fixed position with respect to the housing. The puncturing device is adapted for disposable use in that the housing parts were are irreversibly connected upon enclosing the band-shaped lancet carrier, thereby sealing the band-shaped lancet carrier irremovably in the housing. A reusable handling device can also be used with the puncturing device.
