Full-automatic magnetic-bead time resolution fluorescence immunoassay analyzer

Abstract

The invention discloses a full-automatic magnetic-bead time resolution fluorescence immunoassay analyzer. The analyzer is divided into an inner chamber and an outer chamber by a rack; an electronic element box is fixed on the upper layer of the inner chamber, a dark chamber shell is positioned on the lower layer of the inner chamber, a dark chamber door device is arranged on the rack, and a dark chamber space of which one side is openable is formed by the dark chamber door device and the dark chamber shell; a tray module is positioned on the lower layer of the outer chamber, and a plurality ofreagent strips can be placed on the tray module, and are conveyed to the lower layer of the inner chamber or are withdrawn to the lower layer of the outer chamber; a puncturing liquid relief module is positioned on the upper layer of the outer chamber, can automatically pierce the film of the top surface of each reagent strip, and automatically suck or discharge liquid in the reagent; a scanningand value reading module is positioned on the lower layer of the inner chamber, is positioned in the dark chamber shell, and is used for triggering and reading fluorescence information of the reagentstrips after incubation; and by reasonable arrangement of the inner chamber and the outer chamber and in combination with compact and scientific design of the related functional module, the structureis simple and compact, the cost is low, furthermore, the degree of automation of the integral instrument is increased, and thus, the full-automatic magnetic-bead time resolution fluorescence immunoassay analyzer is quite suitable for being used and popularized in China medical units.

Description

technical field [0001] The invention relates to the field of time-resolved fluorescence immunoassay instruments used in industries such as in vitro diagnosis and biomedicine, animal epidemics, food safety, and drug screening, and in particular to a fully automatic magnetic bead time-resolved fluorescence immunoassay with simple and compact structure and a high degree of automation. Analyzer. Background technique [0002] Point of Care Testing (POCT) is an important development direction of marker immune technology in the in vitro diagnostic industry in recent years, and it is also the fastest growing branch. The technologies involved in POCT are diverse. In general, they can be divided into simple color development, enzyme labeling, immunoassay, optical and electrical biosensors, electrochemical detection, spectrophotometry, and biochips. [0003] Labeled immunology technology has experienced more than 100 years of development history. According to different markers, the de...
