Claim:
A patient's skin puncturing device comprising a body, inside of which a puncturing needle and at least one deformable arm are guided, and a push button, whereas between said body and said push button activating elements are placed, said activating elements enable to force said push button into said body when a pre-set thrust force is exceeded, and the puncturing needle is driven by a thrust force in a puncturing direction applied by said push button by a membrane, which is broken after resting the puncturing needle on an abutting surface in said body, wherein after breaking the membrane and the patient's skin puncture by the puncturing needle and during application of the thrust force, the puncturing needle is withdrawn inwards the body in a retracting direction opposite to the puncturing direction due to a transfer of the thrust force from the push button to the retracting direction by the at least one deformable arm being guided in the body and deformed to push the puncturing needle in the retracting direction, wherein the push button and the at least one deformable arm are integrally formed with each other constituting one element.
