Abstract

An electrochemical test paper with the function of detecting the injection state of samples. The electrochemical test paper includes an insulating substrate; an electrode system, placed on the insulating substrate, the electrode system includes a measuring electrode group, an identification electrode group and a resistance, wherein the measuring electrode group includes a reference electrode and a working electrode insulated from each other The electrode, the identification electrode group includes a first identification electrode and a second identification electrode connected by the resistance; and an insulating layer covering a part of the electrode system, wherein a part of the electrode system not covered by the insulating layer forms a a reaction zone. When a liquid sample is injected into the reaction area from the open end, it touches the measurement electrode set and the identification electrode set sequentially.

Description

technical field [0001] The present invention relates to an electrochemical test paper, in particular to an electrochemical test paper that can start an instrument, confirm whether the test paper is placed in the correct position of the instrument, identify whether a sample enters a reaction zone, and confirm that the sample properly covers the reaction zone. Background technique [0002] In the detection of medicine or biochemistry, the use of electrochemical test paper has been a common technology. The traditional electrochemical test paper has two electrodes, after the sample is injected into the reaction area of ​​the test paper, the electrical properties of the sample are measured by these two electrodes. However, under such a structure, it is impossible to determine whether the sample has completely covered the two electrodes before measurement, and it is even impossible to determine whether the sample has been injected into the reaction area. [0003] To solve the abo...
