Abstract
A system and method for carrying out the withdrawal of body fluid with as little body fluid as possible visible to the user at the end of the process. The present invention provides a pressure piece for exerting pressure on a body part. The pressure piece is moved relative to a support for the body part, and in the final phase of fluid withdrawal, the compressive or resistive force of the pressure piece on the body part is reduced in order to avoid the escape of body fluid from the puncture site. The support results in a defined positioning of the body part that rests against it for the lancing process, whereas the relative movement of the pressure piece enables an additional increase in pressure and thus an improved collection of fluid.
