Embodiment Construction

[0029] Figures 1 to 3 Various embodiment examples of tape cassettes according to the invention are shown in which the test tape is held under tensile strain. figure 1 Cassette 10 with case 11 is shown. The housing 11 is divided into a first holder 12 for a storage unit 20 and a second holder 13 for a waste unit 24 . By means of the partition wall 14 the holders 12 , 13 are separated from each other, thereby separating the storage unit 20 from the waste unit 24 . One side wall 12 a , 13 a of each of the holders 12 , 13 overlaps in a region 19 to form an opening 16 equipped with a seal 17 . In the holder 13 a further opening 15 for a waste unit 24 is provided. A deflector head 18 for the test strip 30 is integrated into the housing 10 .

[0030]The storage unit 20 has a reel or reel shell 21 that holds unused inspection tape 30 wound around a reel 22 to form a supply reel 23 . The waste unit 24 is similarly equipped with a reel housing 25 that holds used test tape wound on...

Abstract

The present invention concerns a tape magazine especially for a hand-held device for analysing a body fluid with a test tape that can be unwound from a storage unit and wound onto a waste unit where the waste unit can be driven in order to wind forward the test tape. The invention provides that a lock which keeps the test tape under tension is integrated in the tape magazine at least on the storage unit. The present invention also concerns a hand-held device with such a tape magazine. The present invention also concerns a hand-held device with a mechanical drive for the test tape and a disposable hand-held device with polymer-based electronic components.

Description

technical field [0001] The invention relates to a cassette for a handheld device for examining body fluids, the cassette comprising a test strip, a storage unit for unused test strips and a waste unit for used test strips, wherein the waste unit is driven, to wind the tape forward. Background technique [0002] Inside the cassette, unused test tape sections are pulled from a supply reel and guided over a receiving device, where it collects a body fluid sample. The now used test tape section is then wound onto a waste reel. A detection device that measures the sample and transmits the measurement results to the evaluation device is attached to the receiving unit. [0003] The cassette is preferably used in blood glucose measuring instruments for diabetics who rely on continuous monitoring of their blood glucose levels. The test strip allows for in-device blood glucose testing after application of capillary blood, for example from a finger pad. For this purpose, a pluralit...
