Medical turntable type multi-project fluorescent immunization analyzer

Abstract

The invention discloses a medical turntable type multi-project fluorescent immunization analyzer, which comprises an automatic casing, a display screen, a thermal-sensitive printer, a power switch button, a card slot, an automatic card feeding assembly, an electric turntable assembly, a barcode recognition assembly, and a detection and analysis assembly. The automatic card feeding assembly includes a fixed bracket, a screw motor, a clamp slot connecting plate, a clamp slot and a micro switch. A semiconductor laser is used for emitting laser with the specific wavelength to irradiate a sample and fluorescence with the certain wavelength is excited; the fluorescent light intensity is received by a photosensitive diode and an optical signal is converted into a voltage signal; and the concentration value of the measured object is negatively correlated with the fluorescent light intensity. Therefore, the concentration and content of the measured object are measured. The batch detection and multi-item detection are realized; the labor intensity of the testing personnel is reduced; the requirements of high efficiency and accuracy of detection are met.

Description

technical field [0001] The invention relates to the field of analysis instruments, in particular to a medical turntable multi-item fluorescence immunoassay analyzer. Background technique [0002] The detection principle of the fluorescence immunoassay analyzer is based on the immunofluorescence detection method designed on the basis of immunofluorescence technology, chromatography technology and laser induction technology. Using fluorescein as a label, it is combined with a known antibody or antigen, and then the fluorescently labeled antibody or antigen is used as a standard reagent. Using the test liquid as the mobile phase, the analyte moves on the chromatographic strip through capillary action, the analyte undergoes a specific immune reaction at the T line, and the free substance undergoes an immune reaction at the C line. The concentration of the analyte was tested by the competition method and the sandwich method. First, the semiconductor laser is used to emit laser ...
