Abstract:
1. A microsampler puncturing system for collecting a body fluid sample from a body part, comprising: a sample collection unit having a piercing element, and a puncturing instrument having: a setting device configured to set a defined puncturing depth of the piercing wound, and a control device configured to control the piercing and retraction movement, the piercing and retraction movement including the following sequentially executed movement phases: wherein a mean value of the residual puncturing depth corresponds to the time integral of the residual puncturing depth from the beginning of the collecting phase to the end of the collecting phase divided by the duration of the collecting phase, the setting device is adapted to set the defined puncturing depth independently of the mean value of the residual puncturing depth and the setting device is adapted to set the mean value of the residual puncturing depth independently of the defined puncturing depth.
