Abstract
A blood collection system for collecting blood from a body part for diagnostic purposes, comprising a housing with a lancet guide, by which a lancet is guided on a predetermined puncture path, and a lancet drive for driving a puncturing movement of the lancet on the predetermined puncture path. The puncturing movement comprises a forward movement phase in the direction of puncturing and, after reaching a reversal point, a subsequent retraction movement phase in the direction opposite the puncture direction. The lancet drive has a driving spring, which is arranged behind the lancet and is connected to the lancet during the forward movement phase of the puncturing movement so that the lancet is driven in the puncturing direction. The system comprises an oscillation control device for controlling oscillation of the lancet and the driving spring in such a manner that repeated puncturing of the body part by the lancet is prevented.
