| 20100311154 | TEST STRIP DESIGNED TO IMPROVE SPREADABILITY OF BLOOD - Disclosed is a test strip for measuring medical data, in which a hydrophilic material is introduced to improve the spreadability of blood. Having the structure comprising a blood-filtering layer designed to filter off either or both of erythrocytes and low-density lipoprotein (LDL) cholesterol from an applied blood sample; a reaction layer in which the blood sample free of erythrocytes and/or low-density lipoprotein (LDL) cholesterol is reacted with an reagent, and a hydrophilic material, intercalated between the blood-filtering layer and the reaction layer, for uniformly spreading the blood sample filtered through the filtering layer, the blood-filtering layer and the reaction layer being stacked between the lower support and the upper cover, the test strip prevents the infiltration of erythrocytes into the reaction layer and improves the spreadability of blood to reduce measurement errors, thus bringing about higher reproducibility. | 12-09-2010 |
| 20100311149 | BIOSENSOR - Disclosed herein is a biosensor. The biosensor includes a measuring layer configured to measure whether reaction to a biological sample has occurred.

| 20100304475 | DEVICE FOR COLLECTING SAMPLE - Disclosed herein is a device for collecting a sample, which is intended to dispense a received sample onto a measurement strip. The device includes a main body and a pair of receiving pieces. The receiving pieces protrude from a first end of the main body in such a way as to be spaced apart from each other while facing each other, and receive the sample by capillary force acting on a space which is defined between the receiving pieces and which is open on right, left and bottom sides. The device allows the received sample to be easily transferred to a reaction zone of a measurement strip, and enables the sample to be completely absorbed by the reaction zone because of capillary force in a receiving area when the device comes into contact with the reaction zone of the strip. | 12-02-2010 |
| 20090093012 | REACTION CASSETTE FOR MEASURING THE CONCENTRATION OF GLYCATED HEMOGLOBIN AND MEASURING METHOD THEREOF - 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. | 04-09-2009 |
