Abstract
A system for withdrawing blood from a body part that avoids formation of a drop of blood on the skin surface of the body part after blood removal. The system includes a collecting unit to withdraw blood, a lancing member configured for insertion into the body part and having a capillary to collect blood, and a pressure piece configured to apply pressure to the body part and having an actuator operably connected thereto. The pressure piece is movable relative to a support configured to exert pressure on the body part, and the actuator is configured to reduce the compressive force of the pressure piece after removing an amount of blood, whereby forming a drop of blood on the skin surface of the body part can be avoided.
