ABSTRACT:
A microsampler puncturing system for collecting a body fluid from a body part is described, comprising a sample collection unit having a piercing element, and a puncturing instrument having a drive, by which a sample collection unit is movable on a movement path for piercing the piercing element into the skin of the body part and withdrawing it in a piercing and retraction movement, a setting device for setting the puncturing depth of the piercing wound to be generated, and a control device for controlling the piercing and retraction movement having the following sequentially executed movement phases: a forward phase, a retraction phase, and a collecting phase (S). The setting device is settable independently of the chronological mean <dr> of the defined residual puncturing depth (dr), with reference to the collecting phase.
