20090053108CENTRIFUGAL FORCE-BASED MICROFLUIDIC DEVICE FOR BLOOD CHEMISTRY ANALYSIS - Provided is a microfluidic device that can automatically perform various types of biological blood analysis. In the microfluidic device, a specimen is centrifugally separated and the centrifugally separated specimen is diluted into various dilution ratios. Also, at least two reagents that are required for one reaction and that need to be separately stored are stored in separate chambers, and they are mixed when a reaction is needed. Thus, various conventional blood analyzing reagents can be used as they are or after being minimally processed in the microfluidic device.02-26-2009
20100093105MICROFLUIDIC DEVICE USING CENTRIFUGAL FORCE, METHOD OF MANUFACTURING THE MICROFLUIDIC DEVICE AND SAMPLE ANALYZING METHOD USING THE MICROFLUIDIC DEVICE - Provided is a microfluidic device including: a sample chamber; at least one analyzing unit receiving a sample from the sample chamber and detecting components contained in the sample according to a reaction of the sample and a reagent; and a denaturation detection chamber determining the storage condition of the microfluidic device, wherein the denaturation detection chamber accommodates a material whose light absorption changes according to the temperature and the water thereof04-15-2010
20100099126METHOD OF CALCULATING ENZYMATIC REACTION RATE, COMPUTER PROGRAM PRODUCT AND METHOD OF DETERMINING AMOUNT OF ENZYME IN SAMPLE - A method of calculating an enzymatic reaction rate using the largest frequency value of a slope of a sub-group, a computer program product capable of performing the method of calculating an enzymatic reaction rate, and a method of determining the amount of an enzyme in a sample are provided.04-22-2010
20100101106LYOPHILIZING TRAY EMPLOYING REAGENT CARTRIDGE, LYOPHILIZING SYSTEM EMPLOYING THE SAME, AND METHOD OF PREPARING LYOPHILIZED REAGENT - A method of manufacturing a lyophilized reagent, including mounting a plurality of reagent cartridges in which a liquid reagent is loaded in a tray including one or more tunnel-shaped first rails having opened end portions in a lengthwise direction and an opening formed in the top of the one or more first rails; closing the opened end portions, placing the tray in a lyophilizer and lyophilizing the liquid reagent according to a lyophilizing program.04-29-2010
20100178138APPARATUS AND METHOD FOR LOADING CARTRIDGE HOLDING REACTANT INTO REACTANT CHAMBER OF REACTOR - An apparatus for loading cartridges holding reactants into reactant chambers of a reactor is provided. The apparatus includes: at least one guide rail which transfers a cartridge; an extraction unit comprising at least one storage portion and a blocking portion, the extraction unit moving between a first position in which the blocking portion blocks an outlet of the guide rail and a second position in which the cartridge is output through the outlet of the guide rail and stored by the storage portion; a transfer unit which moves the reactor so that a chamber of the reactor is aligned with the storage portion; and an insertion unit which moves the cartridge from the storage portion into the chamber of the reactor.07-15-2010
