ABSTRACT:
A lancet device for generating a puncture wound in a skin surface, comprising a housing, in which a lancet can be moved on a puncturing path, a lancet drive with a drive rotor that can be driven by a drive spring, a lancet coupling mechanism that transforms a rotational motion of the drive rotor into a puncturing and returning motion of the lancet during a working cycle of the lancet drive, a reference element that is mobile relative to the lancet and relative to the housing and is fixed in a defined position relative to the lancet drive during the puncturing and rests against the surface of the skin with a contact surface thereof such that a puncture wound with a reproducible puncturing depth is generated by the puncturing motion, and a reference element coupling mechanism that is coupled to the lancet drive in order to move the reference element. The invention further relates to a suitable lancet drive assembly for a lancet device of this type.
