    摘要: Lancing system comprising a needle and a lancing device The lancing device comprises a housing with a housing opening that is surrounded by a housing skin contact surface. A lancing depth reference element with a reference skin contact surface is adapted in such a manner that the reference skin contact surface at a reversal point of the lancing movement is in contact with the skin. The lancing depth is determined by the distance between the reference skin contact surface and the tip of the needle element at the reversal point of the lancing movement. The lancing depth reference element is in a stationary defined position relative to the reversal point of the lancing movement. The lancing depth reference element is adapted to stabilize the skin when pressed against the reference skin contact surface with respect to a skin deformation which occurs upon lancing of the skin.

    摘要: Lancing system for extracting a body fluid from the skin of a human or animal comprising a needle element (3) for lancing the skin, a lancing device (2) which includes a lancet drive (15a), by which a lancing movement of the needle element (3) coupled with the lancet drive by means of a coupling mechanism (28) is driven in lancing direction, wherein the lancing device (2) comprises a housing (4) with a housing opening (5) at its in lancing direction front end and the housing opening (5) is surrounded by a housing skin contact surface (7) which is pressed against the skin when using the lancing device (2), the needle element (3) is moved on a predetermined lancing path in a lancing direction in a forward phase of the lancing movement until its tip (3c) enters the skin in order to create a wound and in a return phase of the lancing movement following the reaching of a reversal point corresponding to the lancing depth (S) in the skin is retracted again, a lancing depth reference element (8) with a reference skin contact surface (11) is provided to improve the reproducibility of the lancing depth (S), which is adapted and arranged in such a manner that the reference skin contact surface (11) at the reversal point of the lancing movement is in contact with the skin and the predetermined value of the lancing depth (S) is determined by the distance in lancing direction which prevails at the reversal point of the lancing movement between the reference skin contact surface (11) and the position of the tip (3c) of the needle element (3), at which at the time at which the tip (3c) of the needle element (3) in the forward phase of the lancing movement passes the reference skin contact surface (11) and enters a skin surface which is in contact with said reference skin contact surface, the lancing depth reference element (8) with the reference skin contact surface (11) is in a stationary defined position relative to the reversal point of the lancing movement and the lancing depth reference element (8) is adapted and arranged in such a manner that the skin when pressed against the reference skin contact surface (11) is stabilized with respect to a skin deformation which occurs upon lancing of the skin.
