An automatic dry fluorescence detector

Abstract

The invention discloses an automatic dry-type fluorescence detector, comprising: a sample entry and exit mechanism, including a sample transmission device, a test tube rack capable of placing multiple sample test tubes and a test tube rack placement plate, the test tube rack is installed on the test tube rack placement plate; sampling Mechanism, including a sampling device, a pipetting device, and a buffer for storing multiple buffer boxes; a turntable mechanism, including a turntable, a turntable drive device that drives the loading plate to rotate; a card feeding mechanism, including a card feeding device, a swing device, and at least two Cartridge; the detection mechanism, including the detection head, is used for data collection of the reagent card at the detection position. The invention can reduce a large number of redundant structural designs, thereby saving costs and making the overall structure of the multi-item fluorescence detector more compact. 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 push mechanism (card feeding mechanism) of this 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, increasing 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
