Lancet, in particular for a patient's skin puncturing device for collecting a blood sample for diagnostic purposes, is comprised of the body (1) made of plastic material, in which the needle (2) is coaxially fixed. the tip (3) of the needle (2) is covered by the sheath (4) moulded together with the body (1) and breakably connected therewith. The lancet has additional coaxial with the body (1) and the sheath (4) the guiding member, which is slidably mounted on the guiding member, which is slidably mounted on the guiding segment (5) of the body (1) and is immovably affixed to the sheath (4). The lancet, according to the present invention, insures the required sterility of the tip (3) of the needle (2) and, simultaneously, precludes the tip (3), in particular, in case of the needle of small diameter, from damage during the removal of the sheath (4) from the needle tip (3) before use of the lancet. |
