Problems solved by technology

Therefore, the configuration of the device is complicated, and it is difficult to apply to POC, especially self-examination of patients.
[0012] In addition, in Patent Document 4, a self-blood-sugar examination method that simultaneously measures blood-sugar indicators reflecting current blood-sugar levels and past blood-sugar levels has been proposed, but here, nothing is specified about devices capable of measuring blood-sugar levels and hemoglobin A1c levels openly

Embodiment 1

[0130] use Figure 1 ~ Figure 3 The measuring device 100 shown measures the blood glucose level and the hemoglobin A1c level.

[0131] (blood sugar measurement)

[0132]In the measurement device 100 , the power switch 6 is turned on in advance, the light emitting element 2 a and the light receiving element 3 a are interlocked, and the light emitting element 2 a is irradiated with light having a wavelength of 630 nm in advance. Then, as a test piece (A), prepared were glucose oxidase (GOD) (manufactured by Toyobo Co., Ltd.), peroxidase (POD) (manufactured by Toyobo Co., Ltd.) The test piece of the composition (a) composed of 4-aminoantipyridine / N-ethyl-N-(2-hydroxyl-3-sulfopropyl)-3,5-diphenylamine (MAOS) of the toner, About 5 μL of blood sample (whole blood) was spotted on this test piece (A). Then, the color of the test piece (A) changed from white to blue within a few seconds. This colored test piece (A) is immediately inserted into the test piece insertion port 1 a of t...

Embodiment 2

[0136] use Figure 1 ~ Figure 3 The measuring device 100 shown measures the blood glucose level and the hemoglobin A1c level.

[0137] (blood sugar measurement)

[0138] In the measurement device 100 , the light emitting element 2 a and the light receiving element 3 a are interlocked by turning on the power switch 6 in advance, and further, the light emitting element 2 a is irradiated with light having a wavelength of 550 nm in advance. Then, as a test piece (A), prepared were glucose oxidase (GOD) (manufactured by Toyobo Co., Ltd.), peroxidase (POD) (manufactured by Toyobo Co., Ltd.) The test piece of the composition (a) composed of 4-aminoantipyridine / N-ethyl-N-(2-hydroxyl-3-sulfopropyl) m-toluidine sodium salt (4AA-TOOS) of coloring agent, And about 5 microliters of blood samples (whole blood) were spotted on this test piece (A). Then, the color of the test piece (A) changed from white to purple within a few seconds. This colored test piece (A) is immediately inserted i...

Abstract

Provided is a device and a method, said device enabling the measurement of both of blood glucose level and hemoglobin A1c level, being small-sized and thus portable, allowing the measurement of a small amount of a specimen and, therefore, being usable in POC. The device for measuring the blood glucose level and hemoglobin A1c level of a blood specimen comprises: a test piece-mounting section (1) for detachably mounting test pieces (200) on which the blood specimen is to be spotted; a light-emitting section (2) for emitting light for irradiating the test pieces (200); a light-receiving section (3) for receiving reflected lights from the test pieces (200); and an operating section (4) for calculating the blood glucose level and hemoglobin A1c level of the blood specimen on the basis of photometric values obtained from the light-receiving section (3). As a test piece (200) for measuring the blood glucose level of the blood specimen, a test piece (A), which carries a composition (a) reacting with glucose and showing color development, is mounted. As a test piece (200) for measuring the hemoglobin A1c level of the blood specimen, a test piece (B), which carries a composition (b) reacting with glycated hemoglobin and showing color development, is mounted.

Description

technical field [0001] The present invention relates to a measuring device capable of measuring both a blood sugar level and a hemoglobin A1c value, and a measuring method using the measuring device. Specifically, the measuring device according to the present invention is a small and simple measuring device applicable to so-called POC (Point of Care). Background technique [0002] In recent years, POC (Prompt Point of Care) is gaining attention. The so-called POC refers to the self-examination in the patient's own home, the bedside examination in the hospital, or the examination outside the central examination room, etc., which is performed by the patient or the patient himself, so that the doctor or patient can know the examination result immediately. , so it can be processed quickly, which is expected to greatly contribute to the improvement of the quality of treatment. As a measuring device (POC device) suitable for such a POC, it is required to be small enough to be po...
