Abstract: 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 After breaking membrane (9) and the patient's skin puncture by the needle (4), needle (4) is withdrawn inwards the body (1) due to a transfer of a thrust force from push button (2) by turned down arm (5, 6) guided in the body (1).

Abstract: A patient's skin puncturing device, particularly for collecting a blood sample for diagnostic purposes, including a housing, a lancet slidably positioned inside the housing and having a body with a sheathed puncturing needle seated therein, and a push button positioned at the one end of the housing. Between a face end of the push button and the lancet body a drive spring is placed, and between the other end of the housing, which is provided with an opening for the puncturing needle, and the lancet body a return spring is placed. Between the housing and the lancet body is placed a lancet actuation lock, preferably in the form of interlocks of a washer. The device has a drive spring catch, preferably in the form of grabs of the washer, to preclude the drive spring from following the lancet in the puncture phase and in the retraction phase of the lancet.

Abstract: The device is built of a housing (1), wherein a push button (3) is positioned, and the puncturing needle (5), wherein the push button (3) has arms (7, 8) to guide the push button (3) inside the housing (1), and a driving spring (11), one end of which is linked to the push button (3), and the other end drives the puncturing needle (5), and the puncturing needle (5) has breakable wings (17, 18), which rest against the breaking edge (19) of the housing (1). The device has moreover two return springs (13, 14), each of which is connected to one of the arms (7, 8) of the push button (3), and two side juts (15, 16), each of which is positioned between one of the return springs (13, 14) and the other end of the driving spring (11).
