System for withdrawing body fluid

摘要

System for withdrawing body fluid from a body part (100) in particular the finger pad, comprising a compression unit that can be deformed when the body part is pressed against it and increases the internal pressure in a region of the body part, and a withdrawal device (110). Deformation of the compression unit partially converts the primary pressing movement into a secondary movement which leads to an increase in the internal pressure in a region of the body part. The invention also comprises a system for stimulating the outflow of body fluid using a deformable compression unit.
