摘要

The lancet unit for taking blood samples for diagnostic purposes comprises a drive spring (17) and a rotor which has a working surface (23) with vertices (27) at a maximum distance from its axis of rotation, and is connected to lancet holder in such a way that the lancet point emerges from the lancet opening while the rotor relative to the spring roller is within the angular thrust zone (30) following each vertex.
