Multi-wavelength fluorescence instant detector and detection method thereof

Abstract

The invention discloses a multi-wavelength fluorescence instant detector and a detection method thereof, which relates to the field of medical instruments. The multi-wavelength fluorescence instant detector comprises a card carrier tongue with an accommodating groove, a driving mechanism for driving a movement of the card carrier tongue and a light path module for fluorescence detection. The lightpath module generates illumination light through a plurality of light sources, wavelengths of each illumination light are different and are emitted to a to-be-detected sample through a first dichroiclens to generate fluorescent signals, wavelengths of the each fluorescent signal are also different, the each fluorescent signal passes through a second dichroic lens to form a plurality of fluorescent transmission paths, part of the fluorescent transmission paths are located on a reflected light path of a second dichroic lens, part of the fluorescent transmission paths are located on a transmitted light path of the second dichroic lens, and finally, the fluorescence of different wavelengths is received by corresponding optical components. According to the multi-wavelength fluorescence instant detector and the detection method thereof, multi-wavelength fluorescence instant detection is realized, and the detection efficiency and reliability are improved.

Problems solved by technology

[0003] However, conventional dry fluorescent immunoassays are irradiated with excitation light of a single wavelength, and the demand for excitation light of multiple wavelengths is gradually increasing for the samples to be tested. However, the current multi-wavelength detection methods are all through switching filter sets. Repeating the detection process several times is time-consuming; and the filter set needs to be positioned repeatedly, and its positioning accuracy will be limited by the movement mechanism, and its reliability will be reduced due to movement; and, the extension of time may cause reagent fluorescence attenuation and Degradation, not conducive to detection
