Abstract

Blood removal system for removing blood for diagnostic purposes including a housing, a lancet guide, and a lancet drive with a drive spring. The lancet drive comprises a cocking device, in order to tension the drive spring, a drive rotor that is driven by the drive spring, and an output-side coupling mechanism, by means of which the rotational movement of the drive rotor is converted into the puncturing movement.
