Problems solved by technology

The disadvantage of the existing technology is that because the color gradient on the standard template changes very little, the resolution of the human eye to the color is low and there are certain individual differences in the color recognition by the human eye. Therefore, for the same sample, different tests People often get different detection data, which often happens in practice

Embodiment Construction

[0014] In the structural diagram shown in FIG. 1 , a detection circuit with a single-chip microcomputer 4 as the core is installed inside the housing 1 . The lower part of the casing 1 is connected with a test chamber 2, which can be an integral structure or a split structure that can be assembled and disassembled. The advantage of the overall structure is that it is easy to manufacture, and the advantage of the split structure is that it is convenient to replace the test chamber when needed. In this embodiment, the split structure is adopted. The test chamber is a relatively key part in the present invention. A fixed light source must be used for color detection. In order to prevent the interference of ambient light, the detection of the test sample needs to be carried out in an environment that isolates the ambient light. The test chamber provides such A testing environment. A color sensor 7 and a test light source 8 are installed inside the test chamber 2, and they are ele...

Abstract

The invention discloses a hematoglobin color comparison detecting device which comprises a casing, a test chamber, a color sensor, a test light source and a detection circuit with a singlechip as a core. Before a sample is tested, color information on a standard color card marked with different hematoglobin contents is collected in the singlechip, and then the color information of blood sample is collected. The singlechip compares the color information of the tested sample with the color information on the standard color card, and the hematoglobin content of the tested sample can be detected. The hematoglobin color comparison detecting device has the advantages of simple use, fast detection, exact data, low use cost, carrying convenience, and the like and is especially fit for the occasion without using large testing instrument, such as blood collecting station, blood collecting car, battleground health center, earthquake stricken area medical team, etc.

Description

Technical field [0001] The invention relates to a medical detection device for detecting hemoglobin content in blood, in particular to a hemoglobin colorimetric detection device for rapidly detecting hemoglobin content by using a colorimetric method. Background technique [0002] Hemoglobin is a respiratory molecule present in red blood cells. It is responsible for transporting oxygen from the lungs to the cells of the body, and it is responsible for transporting carbon dioxide from the cells of the body to the lungs. Certain diseases and trauma can cause a lack of hemoglobin, and other diseases can cause the amount of hemoglobin in the blood to exceed normal levels. At present, the detection of hemoglobin has been widely used in the medical field, such as screening blood donors for anemia, prenatal examination, and child health planning and disease control management. The prior art similar to the present invention is two Chinese patents, No. ZL03200969.0 Chinese invention...
