Handheld Fluorescence Immunoassay Device

Abstract

The invention discloses a handheld fluoroimmunoassay device. The device comprises a shell and an upper cover, the shell and the upper cover enclose an accommodating chamber, a fluorescence data acquisition module, an photoelectric scanning module and a master control module are arranged in the accommodating chamber, and the surface of the upper cover is provided with a touch screen; the fluorescence data acquisition module is arranged above the photoelectric scanning module, and the master control module is respectively connected with the fluorescence data acquisition module, the photoelectricscanning module and the touch screen; the device also comprises a pedestal bottom with a reagent card slot integrated to the photoelectric scanning module; and the position of the fluorescence data acquisition module in the accommodating chamber is moving. The fluorescence data acquisition module includes a plurality of excitation light sources which are light sources having different wavebands respectively, so multi-purpose use of one machine is realized, the detection of multiple fluorescent band samples can be achieved, and the application range of the device is enlarged; and the device adopting the moving fluorescence data acquisition module and fixed reagent card structure has the advantages of compact integral structure layout, small size, and easiness in realization of handheld operation and carrying.

Description

technical field [0001] The invention belongs to the field of fluorescence immunoassay detection, and in particular relates to a hand-held fluorescence immunoassay device suitable for accurate, rapid, convenient and multi-band detection. Background technique [0002] Fluorescence immunoassay technology is a commonly used detection technology in biomedical testing at present. This technology uses the characteristic that the analyte will produce fluorescence under the excitation of specific wavelength light for qualitative and quantitative detection. Fluorescence immunoassay technology has a series of advantages such as high sensitivity, strong specificity, fast detection speed, safety and stability, etc., so it is widely used in clinical detection, endocrine disease detection, infectious disease detection, obstetrics and gynecology disease detection, tumor Marker detection, genetic disease detection, blood and cytology detection and other detection fields have broad applicatio...
