Description

Technical Field

[0001] The utility model relates to the technical field of fluorescent immunoassay analyzer equipment, in particular to a reagent card reciprocating card pushing device for a fluorescent immunoassay analyzer. Background Art

[0002] Immunofluorescence technique, also known as fluorescent antibody technique, is the earliest developed type of labeled immunotechnology. It is a technology established on the basis of immunology, biochemistry and microscopy. For a long time, some scholars have tried to combine antibody molecules with some tracer substances and use antigen-antibody reactions to locate antigen substances in tissues or cells. Immunofluorescence (immunofluorescence technique) Coons et al. first used fluorescein for labeling in 1941 and succeeded. This technique of labeling antibodies with fluorescent substances to locate antigens is called fluorescent antibody technique. The method of tracing or checking corresponding antigens with fluorescent antibodies is called fluorescent antibody method; the method of tracing or checking corresponding antibodies with known fluorescent antigen markers is called fluorescent antigen method. These two methods are collectively called immunofluorescence technique, because fluorescent pigments can not only bind to antibody globulins for detecting or locating various antigens, but also bind to other proteins for detecting or locating antibodies. However, fluorescent antigen technique is rarely used in actual work, so people are accustomed to calling it fluorescent antibody technique, or immunofluorescence technique. The fluorescent antibody method is more commonly used. The method of using immunofluorescence technology to display and examine antigens or hapten substances in cells or tissues is called immunofluorescence cytochemistry (or tissue) technology. Using a fluorescence microscope, you can see the cells or tissues where the fluorescence is located, so as to determine the nature and location of the antigen or antibody, and use quantitative technology (such as flow cytometry) to measure the content. The main characteristics of immunofluorescence technology are: strong specificity, high sensitivity, and fast speed. Fluorescence immunoassay can be further divided into several types according to the reaction system and quantitative method. Compared with radioimmunoassay, fluorescence immunoassay has no radioactive pollution, and most of them are easy to operate and easy to promote. A considerable part of the TDM kits produced abroad belong to this category, and there are also automatic analyzers specially produced for TDM fluorescence polarization immunoassay.

[0003] However, most fluorescent immunoassay analyzers on the market currently do not have the function of reciprocating the reagent card, thereby reducing the detection efficiency of the fluorescent immunoassay analyzer. Therefore, a reagent card reciprocating card pushing device for a fluorescent immunoassay analyzer is proposed to solve the above problem. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0013] The reagent card reciprocating card pushing device for a fluorescent immunoassay analyzer can fix the reagent card inside the rubber card block and move the conveyor belt when in use by setting a conveyor belt mechanism. When the conveyor belt rotates, the reagent card flows into the reagent card clamping mechanism under the thrust of the rubber card block, thereby achieving the effect of facilitating clamping and avoiding the situation that the reagent card is vibrated, falls off and deflects during transportation by the conveyor belt.
