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 opening for applying to a part of a body in which a prick wound is to be produced, the touching element being movable to adjust the puncturing depth in the 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 rotatably connected 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 any rotary movement of the touching element relative to the housing, 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 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 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 any rotary movement of the touching element relative to the carrier, wherein the touching element is enclosed by the intermediate piece at least over part of its length.

15. A lancing device comprising:
-
a lancet drive adapted to drive a lancet to effect a puncturing movement; a housing that encloses the lancet drive; a touching element comprising an opening for applying to a part of a body in which a prick wound is to be produced, the touching element being movable to adjust 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 rotatably connected by a screw thread to an intermediate piece and is movable in the puncturing direction, and the intermediate piece is rotatable relative to the housing; a guide that prevents rotation of the touching element relative to the housing, wherein rotating the touching element and the intermediate piece relative to one another to adjust puncturing depth does not change the rotational orientation 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. - View Dependent Claims (16, 17, 18, 19)

20. A lancing device comprising:
-
a lancet drive adapted to drive a lancet to effect a puncturing movement; a housing that encloses the lancet drive; a touching element comprising an opening for applying to a part of a body in which a prick wound is to be produced, the touching element being movable to adjust 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 rotatably connected by a screw thread to an intermediate piece and is movable in the puncturing direction, and the intermediate piece is rotatable relative to the housing; a guide that prevents rotation of the touching element relative to the housing, wherein there is no rotary movement between the touching element and the housing when the touching element and intermediate piece are rotated relative to one another to adjust puncturing depth; and the touching element is enclosed by the intermediate piece at least over part of its length. - View Dependent Claims (21, 22, 23, 24)
