| 摘要 |
The invention relates to a lancet device for generating a puncture wound in a skin surface, comprising a housing (2), in which a lancet (4) can be moved on a puncturing path, a lancet drive (9) with a drive rotor (12) that can be driven by a drive spring (11), a lancet coupling mechanism (24) that transforms a rotational motion of the drive rotor (12) into a puncturing and returning motion of the lancet (4) during a working cycle of the lancet drive (9), a reference element (14) that is mobile relative to the lancet (4) and relative to the housing (2) and is fixed in a defined position relative to the lancet drive (9) during the puncturing and rests against the surface of the skin with a contact surface (15) thereof such that a puncture wound with a reproducible puncturing depth is generated by the puncturing motion, and a reference element coupling mechanism (38,39) that is coupled to the lancet drive (9) in order to move the reference element (14). The invention further relates to a suitable lancet drive assembly (10) for a lancet device of this type. |
