The fluorescent quantitative analysis meter comprises a machine body, a thermal printer arranged at the top of the machine body and a fishtail handle arranged at the bottom of the machine body, wherein the machine body is of a hollow rectangular solid structure, a liquid crystal display screen used for displaying data is arranged on the front of the machine body, and a detection entrance used for placing a to-be-detected object is formed in the side surface of the machine body; and a keyboard used for information interaction is arranged on the front of the fishtail handle, and a battery holder used for placing a battery is arranged on the back of the machinebody. The fluorescent quantitative analysis meter provided by the invention is compact in structure, portable and easy to use, human blood and urine are analyzed and detected based on fluorescence immunoassay and immunochromatography technical principles, and the technical problems that a mechanical transmission structure of an existing analysis meter is complex and utilization rate of an opticalcircuit device is low are solved.

Description

technical field [0001] The invention relates to the technical field of medical detection instruments, in particular to a fluorescence quantitative analyzer. Background technique [0002] Fluorescence immunoassay (FIA) is a microanalysis method developed in recent years, and it is one of the most sensitive microanalysis techniques at present. Molecules of certain substances can absorb energy and emit fluorescence. According to the fluorescence spectrum and fluorescence intensity, the method of qualitative or quantitative substance is called fluorescence analysis. Fluorescence immunoassay (FIA) has the advantages of high sensitivity, strong selectivity, less sample required, and simple method. The lower limit of determination of this method is usually 2 to 4 orders of magnitude higher than that of spectrophotometry, and it is widely used in biochemical analysis. . [0003] The current general-purpose fluorescent quantitative detectors are usually bulky and not convenient for...
