Abstract

The invention relates to a puncturing system for generating a puncture wound for obtaining a sample of a body fluid, comprising a press-on part to be pressed onto a body part in which a puncture wound is to be generated, a triggering means, by the actuation of which a user can trigger a puncturing motion of a puncturing element after the press-on part is pressed on, and a testing facility for determining at least one test parameter on which a sample-obtaining probability depends. A securing facility is also provided that, in a locked state, locks the triggering means such that no puncturing motion can be triggered, and, in a triggering state, releases the triggering means such that a puncturing motion can be triggered by actuation thereof, whereby the securing facility is transitioned from the locked state to the triggering state by the testing facility when the test parameter determined by the testing facility meets defined minimum requirements. A signaling facility is also provided for signaling a transition of the securing facility to the triggering state and/or for signaling that the securing facility is in the triggering state. The invention also relates to a method for prepar…
