Abstract:
1. A lancing device, comprising: a housing; a lancet drive disposed in the housing and including a drive rotor driven by a drive spring; a first coupling mechanism disposed in the housing and including a lancet connecting arm configured to connect to a lancet, the first coupling mechanism transforming motion of the drive rotor into reciprocating motion of the lancet connecting arm; a reference element that is moveable relative to the housing and relative to the lancet connecting arm, the reference element having a contact surface adapted to contact skin to be punctured during the reciprocating motion of the lancet connecting arm; and a second coupling mechanism which couples the reference element to the lancet drive, wherein movement of the lancet drive is transformed into movement of the reference element, the second coupling mechanism transforming movement of the drive rotor into a return movement of the reference element.
