Fluorescence quantitative detector

Abstract

The invention relates to a fluorescence quantitative detector which comprises an excitation light source module, a photoelectric conversion module, a control analysis module, and a software module; the excitation light source module comprises a first laser module assembly and a second laser module assembly; the first laser module assembly is used for emitting an excitation light beam A to a detection zone of a reagent strip; the second laser module assembly is used for emitting an excitation light beam B to a coding zone of a reagent strip; the photoelectric conversion module is used for receiving a reflected fluorescence signal C and a laser signal D, and performing photoelectric signal conversion; the control analysis module comprises a main circuit, a motor, and a display screen, and the control analysis module is used for treating and receiving electric signals outputted by the photoelectric conversion module; the fluorescence quantitative detector is provided with a reagent strip slot and an ID card slot which are used for accommodating the reagent strip and a calibration chip ID card; the motor is used for driving the reagent strip to move. the fluorescence quantitative detector of the invention adopts a specially-designed optical system and compensating circuit, and makes immunofluorescence quantitative detection become more sensitive and accurate.

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. [0003] 【Background technique】 [0004] 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 combin...

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.
