Abstract

Disclosed are an electrochemical biosensor which comprises a production lot information identification portion, on which information is recorded in a magnetization mark, and a measuring device which can automatically identify the production lot information of the biosensor with the insertion of the electrochemical biosensor into the measuring device. The electrochemical biosensor and the measuring device thereof can record production lot information in the form of magnetization marks on an electrochemical biosensor strip and read the information as digital signals through a magnetoresistance sensor device, which can be mounted on the surface of a circuit board using Surface Mounted Technology (SMT). Without the need for a high-priced filter or a complicated calculation system, the magnetic detector system has a simple construction and realizes economic efficiency in the construction of the measuring device. Also, the measuring device automatically identifies the production lot information recorded on the biosensor, so that inconvenience and the frequency of errors, which occur when a user personally inputs the production lot information, can be reduced, with the result that the measured values can be conveniently and accurately acquired.

Description

technical field [0001] The invention relates to an electrochemical biosensor and a biosensor measuring device. Background technique [0002] The importance of periodic monitoring of blood glucose levels is increasingly emphasized for the purpose of diagnosing and preventing diabetes. Currently, strip-type biosensors designed for use in handheld reading devices allow individuals to easily monitor glucose levels in the blood. [0003] A number of commercially available biosensors use electrochemical techniques to measure glucose levels in blood samples. The principle of electrochemical technology is based on the following reaction 1. [0004] [reaction 1] [0005] Glucose + GOx-FAD → Gluconic Acid + GOx-FADH 2 [0006] GOx-FADH 2 +M ox →GOx-FAD+M red [0007] Among them, GOx represents glucose oxidase; GOx-FAD and GOx-FADH 2 Represent the oxidation state and reduction state of glucose-related FAD (flavin adenine dinucleotide), which is a cofactor required for the cat...
