TEST TAPE CASSETTE AND ANALYTICAL TEST TAPE THEREFOR

摘要

A test tape cassette is disclosed that includes a cassette housing and an analytical test tape. The test tape includes a plurality of analytical test elements, a spreading fabric for applying a body fluid, and an underlying reagent layer for detecting an analyte in the body fluid. The cassette housing has an application tip that has a guide path extending longitudinally to the test tape in an arched-shape and is uncurved at right angles thereto for supporting the test tape in a kink-free manner. The guide path has an apex area with a central opening that delimits a measuring window for an optical measurement on the test elements.

主权项

1. A test tape cassette for insertion into a hand-held device, the cassette comprising:
a cassette housing for storing at least two tape spools; and an analytical test tape that can be wound forwards by means of the at least two tape spools, wherein the analytical test tape comprises a plurality of analytical test elements stored thereupon having a spreading fabric and an underlying reagent layer for detecting an analyte of interest, wherein the cassette housing has an application tip that deflects the analytical test tape to provide at least one of the plurality of test elements, the application tip having a guide path that extends in an arch shape longitudinally to the analytical test tape and is uncurved at right angles thereto for supporting the analytical test tape in a kink-free manner, wherein an apex area of the guide path delimits a central opening as a measuring window for an optical measurement on the at least one of the plurality of test elements, and wherein the test tape when under tension is supported in a planar fashion on the guide path so that the spreading fabric lies gap-free on the underlying reagent layer.
