Electrochemical measuring system with multizone sensors
First Claim
1. A sensor for use in an electrochemical measuring apparatus adapted to receive the sensor for carrying out at least two successive measurements of the same physicochemical characteristic or of a concentration of the same component present in a solution, an effluent or a fluid, said sensor comprising:
- a thin insulating support in the form of a strip,at least two current collectors of conducting material arranged on said strip and electrically insulated from each other,at least one insulating covering partially covering a surface of the strip and the current collectors to delimit at least one contact zone and at least two consecutive windows providing access to the current collectors, said current collectors constituting electrodes and said windows delimiting on the surface of the strip a plurality of open measuring zones each for receiving and holding a drop of said solution, effluent or fluid to provide on the surface of the sensor a plurality of active sequentially disposable measuring zones for carrying out said at least two measurements by introducing a single said sensor into said measuring apparatus.

Abstract
A small sensor for an electrochemical measuring system composed of a measuring apparatus (50) having an electronic circuit (60), a connecting device (64), a positioning and advancing device (56, 57) and an eliminating device (59, 53). The apparatus is adapted to receive the sensor (40), which has a plurality of active, successively disposable measuring zones (34). The sensor has applications in the quantitative analysis of glucose in the blood.
