Immunochromatographic analysis instrument

Abstract

The invention provides an immunochromatographic analysis instrument. The instrument comprises a bottom plate, a first vertical plate, a second vertical plate, an upper computer, a camera, an electrictelescopic rod, a colorimetric plate and a test paper clamping plate; before analysis and testing, test paper is fixed on the test paper clamping plate; a sample is dropwise added and stands for a period of time; the test paper clamping plate is pushed into the collection cavity between the first vertical plate and the second vertical plate; the upper computer controls the electric telescopic rodto drive the colorimetric plate to slide in the strip-shaped groove; therefore, different color areas on the colorimetric plate are moved to the lower part of the collection cavity; the camera performs image acquisition on the color areas of the test paper and the colorimetric plate; color matching is carried out by the upper computer; when the color matching is successful, the corresponding colorand the corresponding concentration information are displayed on the screen, and the image information of the test paper and the colorimetric plate is simultaneously acquired in the analysis process,so that the interference of illumination or air quality and the like of the external environment on the color is avoided, and the error generated in the analysis process is reduced.

Description

technical field [0001] The invention relates to the technical field of immunoassay, in particular to an immunochromatography analysis instrument. Background technique [0002] Immunochromatography (immunochromatography) is a rapid diagnostic technique that has emerged in recent years. Its principle is to fix specific antibodies on a certain zone of the nitrocellulose membrane first, and when one end of the dry nitrocellulose membrane is immersed in the sample (urine or serum), the sample will move forward along the membrane due to capillary action, and when it moves to the area where the antibody is immobilized, the corresponding antigen in the sample will specifically bind to the antibody. Gold or immunoenzyme staining can make the area show a certain color, and realize specific immunodiagnosis. [0003] At present, the sample concentration is generally judged by the color category and depth of the color-developed area. The method used is to process and judge the color-dev...

Problems solved by technology

[0003] At present, the sample concentration is generally judged by the color category and depth of the color-developed area. The method used is to process and judge the color-developed area by the camera, and there is a large error in this method. The comparison stored in the software The color is tested under ideal conditions, but when the camera captures the color rendering area, it will be affected by the ambient light, air quality, etc., resulting in a large discrepancy between the color rendering area captured by the camera and the actual situation. This leads to a large error in the final sample concentration value, which is not conducive to specific immunodiagnosis
