Abstract:
1. A puncturing system for generating a puncture wound for obtaining a sample of a body fluid, the puncturing system comprising: a housing which contains components of the puncturing system; a puncturing element movable relative to the housing in a puncturing direction to generate a puncture wound in a body part; a press-on part configured to be pressed onto the body part and having an opening for the lancet tip to puncture the body part; a trigger, a manual actuation of which causes the puncturing element to move in the puncturing direction; a testing facility for determining at least one test parameter on which a sample-obtaining probability depends; a securing facility having a locked state and a triggering state, wherein in the locked state the securing facility prevents the trigger from being actuated, and in the triggering state, the securing facility releases the trigger to allow the manual actuation, the securing facility being transitioned from the locked state to the triggering state when the at least one test parameter determined by the testing facility meets defined minimum requirements, wherein, the puncturing element is movable in the puncturing direction to generate a puncture wound only if (i) the testing facility determines a test parameter that indicates a successful puncture can be executed and if (ii) the trigger is subsequently actuated; and a signaling facility that signals a transition of the securing facility from the locked state to the triggering state or signals that the securing facility is in the triggering state, wherein the signaling facility comprises a device which produces an audible signal or comprises a visual indicator disposed on or visible from the exterior of the housing.
