Puncturing system and tape cassette
First Claim
1. A puncturing system comprising:
- a carrier tape that has a plurality of lancets;
a first reel on which the carrier tape with unused lancets is wound up;
a second reel for winding up carrier tape portions with used lancets;
wherein the first reel and the second reel are arranged in a side-by-side manner;
a reel drive configured to rotate the second reel and to thereby bring the lancets carried by the carrier tape successively into a position for use, and thereby to unwind the carrier tape from the first reel and to wind the carrier tape up on the second reel;
a puncturing drive for accelerating lancets that are in the position for use for a puncturing action; and
wherein the carrier tape is twisted between the first and the second reels only in one direction by at least one quarter turn.

Abstract
A puncturing system includes a support tape (1) that supports a plurality of lancets (2), a first reel (3) onto which the support tape (1) with unused lancets (2) is wound, a second reel (4) on which portions of the support tape with used lancets (2) are to be wound, a winding mechanism which, by turning the second reel (4), brings the lancets (2) supported by the support tape (1) to a position of use one after another and thus unwinds the support tape (1) from the first reel (3) and winds it onto the second reel (4), and a puncturing drive mechanism (7) with which lancets (2) located in the position of use are accelerated in order to puncture the skin. The support tape (1) between the first and second reels (3, 4) is twisted only in one direction of rotation by at least a quarter turn, preferably by at least a half turn.
