摘要

TEST TAPE CASSETTE AND ANALYTICAL TEST TAPE THEREFOR A test tape cassette for insertion into a hand-held device, in particular for blood sugar tests, comprising a cassette housing (50) for storing tape spools, an analytical test tape (20) that can be wound forwards by means of the tape spools (54, 58), a plurality of analytical test elements (24) stored on the test tape (20) which have a spreading fabric (30) for applying body fluid and an underlying reagent layer (36) for detecting an analyte in the body fluid, wherein the cassette housing (50) has an application tip (18) that deflects the test tape (20) in order to provide the test elements (24), wherein the application tip (18) has a guide path (68) which extends in an arch shape longitudinally to the test tape and is uncurved at right angles thereto for supporting the test tape (20) in a kink-free manner, the apex area of the guide path (68) delimits a central opening as a measuring window (70) for an optical measurement on the test elements (24) and the test tape (20) under tension is supported in a planar fashion on the guide path (68) such that the spreading fabric (30) lies gap-free on the reagent layer (36), and wherein the reagent layer (36) viewed in the tape transverse direction is narrower than the test tape (20) and wider than the measuring window (70).
