Patent ID: 7695608

Claim:
An electrochemical biosensor measuring device quantitatively determining analytes using an electrochemical biosensor, wherein the electrochemical biosensor comprises, a plurality of electrodes, capillary sample cell, reaction reagent layers, electrical connection portions; and a production lot information identification portion configured such that production lot information is recorded on at least one insulating plate; wherein the production lot information identification portion configured such that the production lot information is recorded thereon has infrared absorption/reflection marks, which indicate information about differences between production lots through printing of colored or colorless materials or attachment of transparent films, having differences in absorbency or reflectivity of infrared rays, in conformity of a predetermined pattern; wherein a number of the infrared absorption/reflection marks ranges 1 to 10; and wherein the electrochemical biosensor measuring device comprises a plurality of integrated photo-reflector sensing devices that emit and receive reflected infrared rays in one component chip mounted on the same PCB of the electrochemical measuring device to identify the infrared absorbing/reflecting production lot information recorded on the production lot information identification portion of the biosensor.
