Lancing device
First Claim
1. A lancing device comprising:
- a lancet drive adapted to drive a lancet to effect a puncturing movement;
a housing that encloses the lancet drive; and
a touching element comprising an eccentrically arranged opening for applying a part of a body in which a prick wound is to be produced, the touching element being movable for the purpose of adjusting the puncturing depth in a puncturing direction relative to the lancet drive, wherein;
the touching element is adapted to directly contact the body when the prick wound is produced,the touching element is connected rotatably by a screw thread to an intermediate piece and is movable in the puncturing direction,the intermediate piece is rotatable relative to the housing,the lancing device comprises a guide that prevents rotation of the touching element relative to the housing, wherein the guide ensures that the eccentrically arranged opening of the touching element retains its orientation relative to the housing irrespective of the adjusted puncturing depth, andthe touching element is enclosed by the intermediate piece at least over part of its length.

Abstract
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.

14. A puncturing depth adjusting unit for a lancing device adapted to produce a prick wound by use with a lancet, the puncturing depth adjusting unit comprising:
-
a touching element with an eccentrically arranged opening for applying a part of a body in which a prick wound is to be produced, the touching element adapted to directly contact the body when the prick wound is produced; an intermediate piece on which the touching element is fastened by means of a thread to allow it to rotate and to move in a puncturing direction; a carrier on which the intermediate piece is rotatably and movably fastened; and a guide preventing rotary movement of the touching element relative to the carrier, wherein the guide ensures that the eccentrically arranged opening of the touching element retains its orientation relative to the carrier irrespective of the adjusted puncturing depth, and wherein the touching element is enclosed by the intermediate piece at least over part of its length.
