Abstract:
System for withdrawing body fluid from a first region of a part of the body, the system comprising:a compression unit being formed to squeeze and at least partially enclose a second region of the body part when the body part is pressed against the unit in a primary direction, the second region adjoining the first region, and to partially convert applied pressure from the body part in the primary direction into a movement of the unit in a secondary direction with a component perpendicular to the primary direction such that an internal pressure is increased in the first region of the body part, a perforation device being formed to produce a body opening in the area of the increased internal pressure of the first region which juts out from the unit, wherein the puncture depth of the perforation device is adjustable, and a control unit is integrated which coordinatively controls the activation of the perforation device and analytical system.
