A patient's skin puncturing device comprises a body (1), inside of which a puncturing needle (4) and at least one turned down arm (5, 6) are guided, and a push button (2). Between body (1) and button (2) activating elements (10, 11, 12, 13) are placed. Activating elements enable push button (2) to be forced into body (1) when a pre-set thrust force is exceeded. Needle (4) is driven by push button (2) by a membrane (9), which is broken after resting the needle (4) upon an abutting surface (16) in body (1). After breaking membrane (9) and the patient's skin puncture by the needle (4), needle (4) is withdrawn inwards the body (1) due to a transfer of a thrust force from push button (2) by turned down arm (5, 6) guided in the body (1). |
