Analyte test strip and analyte meter device

摘要

A test strip with an incorporated optical waveguide and deflectors punched through the optical waveguide allows light to exit through a layer of the test strip and be detected by a photo detector. Using light and a photodetector, these uniquely coded strips are identified. The waveguide can be constructed by sandwiching two layers of the test strip around a light transmissible layer. This configuration allows light to be transmitted through the test strip and out the other end, as well as allowing some light to escape the deflector. This light is detected by a photodetector mounted in the analyte test meter. The deflectors may be placed in patterns such that detection of this light indicates certain characteristics of the strip, such as non-counterfeit, regional identification, type of analyte tested, and coding information.

主权项

1. A test strip comprising:
(a) a top substrate; (b) a bottom substrate; (c) an electrical connector for connection to a meter disposed at a first end; and (d) an electrochemical test cell disposed at a second end;
wherein said electrical connector comprises a first tab formed at the first end of the top substrate, and a second tab formed at the first end of the bottom substrate;wherein the first tab is small in width relative to the second tab;wherein the first tab is not aligned with the second tab: andwherein the second tab is notched in a position selected from the group consisting of: in the middle of the tab, on the edge closest to the first tab, and on the edge farthest from the first tab.
