  • Patent number: 8377684
    Abstract: Disclosed are a test strip and a method for measuring medical data. The test strip comprises an upper cover having one or more application holes; a lower support having one or more detected parts at positions corresponding to detecting units of the measuring apparatus; an erythrocyte and LDL cholesterol-filtering layer designed to filter off both of erythrocytes and LDL cholesterol from an applied blood sample by agglutinating erythrocytes and precipitating LDL cholesterol; and a reaction layer in which the blood sample free of erythrocytes and LDL cholesterol is reacted with an reagent, the filtering layer and the reaction layer being stacked between the lower support and the upper cover. Structured to filter off erythrocytes and low-density lipoprotein (LDL) cholesterol from a blood sample in a single layer, the test strip of the present invention can be made to be slim and allows a low volume of blood to be analyzed.

  • Patent number: 8221703
    Abstract: 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.
