A lancing device comprises a lancet drive to cause a lancet to effect a puncturing movement, a housing that encloses the lancet drive, and a touching element with an opening for applying a part of a body in which a prick wound is to be produced, the touching element being movable relative to the lancet drive for the purpose of adjusting the puncturing depth in a puncturing direction. The touching element is connected rotatably by means of a screw thread to an intermediate piece and is movable in the puncturing direction, while the intermediate piece is rotatable and movable relative to the housing. A guide prevents rotation of the touching element relative to the housing, and the touching element is enclosed by the intermediate piece at least over part of its length.

Lancing device

The present invention provides a puncture aid comprising a housing in which a lancet holder with a lancet is displaceably mounted, the lancet holder being connected to a spring element. The lancet holder has at least one bearing element and the housing has a support surface arranged such that the bearing element rests on the support surface in a first position of the lancet holder. A trigger unit is provided, actuation of which transfer the lancet holder to a second position by means of a relative rotational movement of the bearing element and the support surface, so that the bearing element falls from the support surface in the second position of the lancet holder, and the tensioned spring element at least partially relaxes and moves the lancet holder such that the tip of the lancet emerges from the opening of the housing. The puncture aid includes a blocking element which is arranged such that it blocks a relative rotational movement of the bearing element and the support surface with respect to one another after the trigger unit has transferred the lancet holder to the second position with the result that reuse of the puncture aid is prevented.
