Fluorescent quantitative detection instrument

Abstract

The invention provides a fluorescent quantitative detection instrument. The instrument comprises an excitation light source module, a photoelectric conversion module, a control analysis module and a software system, wherein the excitation light source module comprises a first laser module component and a second laser module component; the first laser module component is used for transmitting an excitation beam A to a detection region on a reagent strip; the second laser module component is used for transmitting an excitation beam B to a coding region on the reagent strip; the photoelectric conversion module is used for receiving a reflected fluorescent signal C and a laser signal D and carrying out photoelectric signal conversion; the control analysis module comprises a main circuit, a motor and a display screen, and is used for processing received electric signals output by the photoelectric conversion module; the fluorescent quantitative detection instrument is provided with a reagent strip slot for placing a reagent strip and an ID card slot for placing a scaler chip ID card; and the motor is used for driving the reagent strip to move. The fluorescent quantitative detection instrument has the following beneficial effect: the specially designed optical system and compensation circuit are adopted, so the fluorescent quantitative detection instrument has higher sensitivity and accuracy in immunofluorescent quantitative detection.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of medical inspection, in particular to a fluorescence quantitative detector for capturing fluorescence signals. 【Background technique】 [0003] Immunofluorescence detection technology has been successful since Coons et al. first used fluorescein for labeling in 1941. This technique of labeling antibodies with fluorescent substances for antigen localization is called fluorescent antibody technique (fluorescent antibody technique). The method of using fluorescent antibody to trace or check the corresponding antigen is called fluorescent antibody method; the method of using known fluorescent antigen markers to trace or check the corresponding antibody is called fluorescent antigen method. These two methods are collectively called immunofluorescence technology, because fluorescent pigments can not only be combined with antibody globulins to detect or localize various antigens, but also can be combined with ot...

AI Technical Summary

Problems solved by technology

The main disadvantages are: the problem of non-specific staining has not been completely resolved, the objectivity of the result judgment is insufficient, and the technical procedures are still relatively complicated

However, the general-purpose fluorescent quantitative detectors in the prior art are usually large in size, which is not convenient for instant inspection, which limits its development in inconvenient transportation and underdeveloped areas.
