| 20080237062 | Electrochemical biosensor and biosensor measuring device - An electrochemical biosensor and a biosensor measuring device. The electrochemical biosensor includes a plurality of electrodes, capillary sample cell portions, reaction reagent layers, electrode connection portions, and a production lot information identification portion. The production lot information identification portion is configured such that the production lot information is recorded thereon has one or more infrared absorption/reflection marks, which indicate information about differences between production lots through the printing and/or attachment of colored or colorless materials, having differences in absorbency or reflectivity of infrared rays, in conformity of a predetermined pattern or through the attachment of transparent films. The electrochemical biosensor measuring device includes a plurality of integrated photo-reflector sensing devices that emit and receive infrared rays to identify the production lot information recorded on the production lot information identification portion of the biosensor. | 10-02-2008 |
| 20090308744 | ELECTROCHEMICAL DETERMINATION SYSTEM OF GLYCATED PROTEINS - Disclosed relates to an electrochemical determination system of glycated proteins, the system comprising: a filtering means for filtering labeled compounds bound to glycated proteins and non-glycated proteins after adding labeling compounds, capable of selectively binding to the glycated proteins to a solution, in which glycated/non-glycated proteins coexist, to be bound all to the glycated proteins; and a quantifying means for quantifying the filtered labeling compounds, not bound to the glycated proteins. The system of the present invention filters the residual labeled compounds left after binding to glycated proteins to quantify, instead of directly quantifying glycated proteins via the known glycated protein determination methods, thus simplifying the configuration of the system that can provide exact determinations with a low cost. Moreover, the electrochemical determination system of glycated proteins of the present invention minimizes the interference that the proteins are absorbed to an analysis device and a sensor in the system, not using immune antibodies that are expensive and have limited lives and, furthermore, not modifying the electrodes of the electrode sensor with antibodies or enzymes, thus facilitating mass production, quality control and circulation of the products. | 12-17-2009 |
| 20100032321 | ELECTROCHEMICAL BIOSENSOR MEASURING SYSTEM - Disclosed is an electrochemical biosensor measuring device which can be used together with an electrochemical biosensor. The biosensor measuring device comprises an electrical connection portion which is electrically connected with the electrodes of the biosensor upon the insertion of the biosensor there into, and a connector having a structure in which at least one light absorption or reflection path sequentially comprising a light emitter-production lot information identification portion-detector unit is provided to identify the production lot information recorded in the biosensor. The electrochemical biosensor measuring device can automatically identify the production lot information of the biosensor, encoded in the form of a hue or hole marks, upon the insertion of the electrochemical biosensor into the measuring device, thereby obviating the need to manually input the production lot information of the biosensor. Thus, 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. | 02-11-2010 |
| 20100126882 | ELECTROCHEMICAL BIOSENSOR MEASURING SYSTEM - Disclosed herein is an electrochemical biosensor measuring device which comprises at least two photodiodes for emitting light beams at regular time intervals in a sequential manner, with the insertion of an electrochemical biosensor thereto, and a detector for sensing the emitted light beams, thereby identifying the production lot information recorded on a production lot information identification portion on the electrochemical biosensor. Thus, the device enjoys economic advantages of not requiring a high-priced optical filter in detecting the light absorbed through or reflected from the production identification information recorded in biosensor and a complicated software algorithm to recover the production lot information. Also, the measuring device automatically identifies the production lot information recorded on the biosensor, so that the frequency of inconvenience and error that occur when a user personally inputs the production lot information of the biosensor can be reduced, with the result that the measured values can be conveniently and accurately acquired. | 05-27-2010 |
| 20110011739 | ELECTROCHEMICAL BIOSENSOR WITH SAMPLE INTRODUCTION CHANNEL CAPABLE OF UNIFORM INTRODUCTION OF SMALL AMOUNT OF SAMPLE - Disclosed is an electrochemical biosensor having a sample introduction channel in which an insulator is employed to introduce a small amount of a sample uniformly and accurately and to adjust an area of a working electrode, thereby guaranteeing the accurate quantitative analysis of a sample. Provided with a sample collection barrier at a sample entrance, the biosensor allows a sample to be introduced at higher accuracy and to be analyzed with higher reproducibility and reliability. | 01-20-2011 |
| 20110147457 | BIOSENSOR MEASURING APPARATUS AND A METHOD THEREOF - A biosensor can be measured by a method that includes: determining malfunction of a production lot information sensing unit; alerting malfunction when the production lot information sensing unit malfunctions; encoding the production lot information through the production lot information sensing unit when the production lot information sensing unit does not malfunction; and detecting a component of a sample through a biosensor strip by using the encoded production lot information. | 06-23-2011 |
