In the present invention, there is disclosed a system for withdrawing body fluid from a body part in particular the finger pad, comprising a compression unit (10) that particularly converts a pressure applied by the body part in a primary direction into a movement in a secondary direction with a component transverse to the primary direction and thus increases the internal pressure in a region of the body part. It further comprises a cannula (60) or a perforation device (80) particularly a lancet or a needle to form an opening in a body within that region with increased inner pressure. The compression unit (10) comprises a region (10a, 10b) made of a deformable material for application of pressure. A system for stimulating outflow of a body fluid form a body part does not comprise the perforation device (80). |
