Problems solved by technology

[0006] Another potential concern when integrating a test strip with a lancing device is that re-use of the test strip could lead to cross-contamination
The lancing portion of the integrated device may have blood retained on it which may infect a second user who may accidentally use the test strip

Embodiment Construction

[0019] figure 1 is a top perspective view of a test strip 20 according to the present invention. In this embodiment, test strip 20 includes a first portion, in this case top layer 34 , a securing mechanism, in this case adhesive layer 38 , and a second portion, in this case bottom layer 36 . In this example embodiment, bottom layer 36 includes a conductive layer disposed on substrate 53 . The conductive layer includes a first working electrode 48 , a second working electrode 50 , a reference electrode 52 and here a frangible mechanism like a fuse 100 in the form of a frangible conductive strip. First working electrode 48, second working electrode 50, and reference electrode 52 may be in the form of conductive sheets. The top layer 34 comprises the lid of the sample receiving cavity 41 . As shown in FIG. 2, in an embodiment of the present invention, top layer 34 also includes integrated lancet 22, reinforcing ribs 24, side raised septa 26, port 30, distal raised septum 28, a...

Abstract

The present invention provides a method of avoiding reusing a test strip which is used for measuring the analyte or the indicator like glucose in physiological liquid like blood, tissue fluid or urine. The present invention also relates to the method of avoiding reusing the test strip which comprises an integrated lancet or a skin puncture device like a needle, a blade or other edge tools. Some kinds of medical devices, such as a glucose test strip, are expected to be used for one test and then are disposed. Because a plurality of chemical reagents in the test strip are not fit for measuring the glucose for second time, the requirement is needed frequently. Some users possibly test the used test strips accidentally. If a glucose meter regulator is used for trying to measure the glucose and outputting a result, which can possibly become the potential problem, therefore, a required one-off test strip and a meter regulator are provided with the appointed method used for avoiding reusing the tested test strip.
