Problems solved by technology

[0003] Based on the principle of reflected light detection and the general structure of the gold standard detection card jamming, when the light emitted by the light source hits the reading window, a part of the light hits the slope on the edge of the window, except for a small part of the light being absorbed, most of the light passes through the white jamming box The reflected light will be received by the receiver together with the light reflected by the test strip. Since the reflected light propagates irregularly on objects with irregular surfaces, the impact on each test result is uncertain. At present None of these products can solve this problem

Abstract

The embodiment of the invention discloses a detecting system for test paper. The system comprises a detecting unit used for information collection, and a colorimetric photosensitive device used for information processing and analysis, wherein the detecting unit is a black detecting card; the colorimetric photosensitive device comprises a light-emitting unit, an optical imaging unit and a photoelectric processing unit. The detecting system has more accurate analytical sensitivity, and through the adoption of the detecting system, the lower limit of the detection of products can be effectively improved, and the range of clinical detection can be enlarged.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a test paper detection system. Background technique [0002] Immunogold labeling technology mainly utilizes the high electron density of gold particles. Dark brown particles can be seen under the microscope at the gold-labeled protein binding site. When these markers gather in large quantities at the corresponding ligands, red or pink can be seen with the naked eye. Spots are therefore used in qualitative or quantitative rapid immunoassays. For quantitative analysis, a detector is usually used to send light to the test card through its own light source, and the reflected light is converted into an electrical signal, and then the color of the reflected light on the test strip is quantitatively compared by analyzing the electrical signal. [0003] Based on the principle of reflected light detection and the general structure of the gold standard detection card jamming, wh...
