According to the automatic dry fluorescence detector disclosed by the invention, lots of redundant structural design can be reduced, so that the cost is reduced, and the overall structure of a multi-item fluorescence detector is compact. The fluorescence detector disclosed by the invention can be applied to fluorescence detection.

Description

technical field [0001] The invention relates to a fluorescence detector, in particular to an automatic dry fluorescence detector. Background technique [0002] Dry fluorescence detection technology is a rapid medical detection technology that has emerged in recent years. This technology is based on a dry fluorescence test card as a carrier, and is used for rapid medical detection through the combination of measurement optical path, barcode reader and test platform. a detection technique. This technique has the advantages of high sensitivity, strong selectivity, less sample required and simple method, and is widely used in medical testing. Dry fluorescence immunoassay analyzer is a detection equipment for the development and application of dry fluorescence detection technology. It is used for immunofluorescence detection of patient samples of all ages by matching with specific dry reagents based on fluorescence immunochromatography. [0003] CN 105548132A discloses a fluore...

Problems solved by technology

[0004] The pushing mechanism (card feeding mechanism) of this kind of reagent card needs to be positioned multiple times during the installation process of the fan-shaped plate, and the installation error is relatively large; and in the subsequent debugging, it is necessary to continuously fine-tune the turntable and the card feeding mechanism to meet the use requirements. This increases the difficulty of debugging and affects the performance of the whole machine; and the design of multiple sets of driving structures also makes the structure of the detector complex, which is not conducive to saving costs and simplifying the structure
