1. A tape cassette for a medical handheld device, comprising:
- a carrier tape, which carries functional elements including at least one of test fields for assaying a sample of a human and/or animal bodily fluid and lancets;
a supply chamber, in which a supply section of the carrier tape comprising unused functional elements is positioned;
a winding unit configured to wind up the carrier tape and draw it through a tape exit opening of the supply chamber, thereby sequentially bringing the functional elements into a usage position; and
a tape guide having a deflection bevel and being positioned in the supply chamber, the tape guide being configured to twist the carrier tape by a quarter-turn in the supply chamber such that the carrier tape in the tape exit opening is oriented transversely to an axis of rotation of the supply section positioned in the supply chamber.

Abstract
A tape cassette for a medical handheld device is disclosed as comprising a carrier tape, which carries test fields for assaying a sample of a human or animal bodily fluid and/or lancets as functional elements, a supply chamber, in which a supply section of the carrier tape comprising unused functional elements is positioned, a winding unit, in order to wind up the carrier tape and draw it through a tape exit opening of the chamber, so that the functional elements may be brought sequentially into a usage position. The carrier tape in the tape exit opening is oriented transversely to the supply section positioned in the supply chamber.

13. A tape cassette for a medical handheld device, comprising:
-
a carrier tape including a surface carrying a plurality of test fields for assaying a fluid sample and a plurality of lancets, each lancet being disposed adjacent a test field; a supply chamber configured to house a supply section of the carrier tape; and a winding unit configured to draw the supply section of the carrier tape out of the supply chamber through a tape exit opening of the supply chamber, thereby sequentially bringing the test fields and the lancets into a usage position whereby, when in the usage position, a plane of the carrier tape is positioned perpendicularly to a plane of the carrier tape when in the supply chamber. - View Dependent Claims (14, 15)

16. A tape cassette for a medical handheld device, comprising:
-
tape means for carrying a plurality of functional elements configured to assay a fluid sample; a roller on which a supply section of the tape means is wound; and means for winding the tape means thereby drawing the supply section of the tape means off of the roller and thus sequentially bringing the functional elements into a usage position wherein the tape means is oriented perpendicular to an orientation of an axis of rotation of the roller.
