A reaction cassette for a glycated hemoglobin meter and a measuring method thereof are provided. The reaction cassette for the glycated hemoglobin meter includes: a first zone receiving a first reagent and a blood sample; a second zone receiving a second reagent; a reaction zone in which the blood sample reacts with the first reagent, or through which the second reagent passes to react with a first blood sample mixture obtained by reacting the blood sample with the first reagent; and a measurement zone measuring an amount of total hemoglobin in the first blood sample mixture, or measuring an amount of glycated hemoglobin in a second blood sample mixture obtained by reacting the first blood sample mixture with the second reagent, wherein the blood sample, the first reagent, and the second reagent move between the reaction zone and the measurement zone according to a rotation angle of the reaction cassette when the reaction cassette is rotated. Therefore, since the reaction cassette rotates automatically, it is possible to measure the amount of glycated hemoglobin in a blood sample through simple manipulation and reduce a manufacturing time. Furthermore, since reagents are supplied to the reaction cassette from a separate reagent pack, it is possible to resolve storage and distribution problems of the reaction cassette, which occur when reagents are stored in the reaction cassette.

Reaction cassette for measuring the concentration of glycated hemoglobin and measuring method thereof

An LDMOS device includes a gate which is formed on and/over over a substrate; a source and a drain which are arranged to be separated from each other on both sides of the substrate with the gate interposed therebetween; and a field oxide film formed to have a step between the gate and the drain. The LDMOS device further includes a drift region formed of first conduction type impurity ions between the gate and the drain in the substrate; and at least one internal field ring formed in the drift region by selectively implanting a second conduction type impurity in accordance with the step of the field oxide film.

Lateral double diffused metal oxide semiconductor device and method of manufacturing the same

Provided is a reagent vessel which is inserted into a measuring cassette for measuring a biological sample. The reagent vessel includes: a reagent storage unit including at least one space in which a reagent that is to react with the biological sample is stored; and an adhesive cover sealing up the at least one space in which the reagent is stored, and being stripped off to discharge the reagent from the at least one space when the reagent vessel is inserted into the measuring cassette. Therefore, since a plurality of reagents are poured simultaneously and automatically into a measuring cassette through a reagent vessel, it is possible to simplify manipulations and minimize a measuring time. Furthermore, it is possible to resolve problems regarding storage and distribution of reagents.

Reagent vessel

A biosensor measuring an analyte contained in a sample is provided, including: an insulative lower substrate that has at least one electrode on which an enzyme reaction layer reacting with the analyte is formed; an upper substrate that faces the lower substrate and is made of a conductive material; and an adhesive layer that has a sample feed with a predetermined height on the enzyme reaction layer and attaches the upper and lower substrates to each other, where an end of the upper substrate acts as an electrode in which an electron-transfer mediator contained in the enzyme reaction layer is oxidized or reduced, and the other end acts as an electrical contact part that electrically contacts a measurement unit.

Biosensor

A biosensor, for use in measurement of an analyte, includes a microporous membrane support, a first electrode system, a second electrode system, and a pair of insulating films. The first electrode system is formed on the surface of the microporous membrane support and the second electrode system is formed on the opposite surface of the microporous membrane support. The biosensor enables a rapid, simple, separation-free, and selective detection of the analytes. The biosensor does not require any bulky additional electrode, so that miniaturization, point-of-car testing, and disposability can be achieved.
