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breaking the membrane (9) and the patient's skin puncture by the puncturing needle (4), the puncturing needle (4) is withdrawn inwards the body (1) due to a transfer of a thrust force from the push button (2) by said turned down arm (5, 6) guided in the body (1).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