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

摘要

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.

主权项

1. A reaction cassette for a glycated hemoglobin meter, the reaction cassette comprising:
a first zone for receiving a reagent which selectively reacts with glycated hemoglobin and a blood sample; a second zone for receiving a washing solution; a measurement zone for measuring an amount of total hemoglobin in a blood sample mixture which is a mixture of the reagent and the blood sample, and measuring an amount of glycated hemoglobin in the blood sample mixture from which non-glycinated hemoglobin is removed; and a delivery guide unit configured to guide the blood sample mixture to move from the first zone to the measurement zone, without passing through the second zone, according to rotation angles of the reaction cassette, wherein the non-glycinated hemoglobin is physically removed from the blood sample mixture by washing the blood sample mixture with the washing solution, wherein the reaction cassette is configured such that the blood sample mixture is moved from the first zone to the measurement zone, without passing through the second zone, by gravity when the reaction cassette is rotated in a first direction, and wherein the reaction cassette is configured such that the washing solution is moved from the second zone to the first zone by gravity when the reaction cassette is rotated in a second direction.
