Full-automatic immunity analyzer and analysis method thereof

Abstract

The invention belongs to the field of medical instruments, and discloses a full-automatic immunity analyzer and an analysis method thereof. Samples are stored on a sample storage and transfer assembly, reagents are stored on a reagent loading assembly, and a certain amount of clean empty reaction cups are borne on a reaction cup supply assembly; a dispensing assembly dispenses quantitative samples and reagents into the reaction cups from the sample storage and transfer assembly, the reaction cups containing the samples and the reagents are uniformly mixed through a uniform mixing assembly, and the sample reagents are fully dispersed; a reaction disc assembly performs constant-temperature incubation on the uniformly mixed reaction cups; a magnetic separation and cleaning assembly is used for cleaning and separating the reaction cups after constant-temperature incubation of the reaction disc assembly is finished, an optical measurement assembly is used for measuring optical signals of the reaction cups which are added with substrates and have stable reaction, and a waste liquid recovery assembly is used for absorbing waste liquid of the reaction cups with measured optical signals, so that the whole cycle time is shortened, the test flux is improved, the operation process is simple, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic immune analyzer and an analysis method. Background technique [0002] Chemiluminescence immunoassay is rapidly popularized due to its advantages of high sensitivity, good specificity and high degree of automation, and is widely used in the fields of tumor markers, infectious diseases, endocrine function, hormones and other medical diagnosis. There are more and more testing needs, and the requirements are getting higher and higher. [0003] The chemiluminescence immunoassay analyzer mainly includes a sample storage and transport assembly, a reagent loading assembly, a cuvette supply assembly, a dispensing assembly, a buffer disk assembly, a mixing assembly, a reaction disk assembly, a magnetic separation and cleaning assembly, a photodetection assembly and a cuvette transfer assembly. And so on, and the operations such as loading and transferring reaction cup...

AI Technical Summary

Problems solved by technology

[0003] The chemiluminescence immunoassay analyzer mainly includes sample storage and transfer components, reagent loading components, cuvette supply components, dispensing components, buffer plate components, mixing components, reaction plate components, magnetic separation cleaning components, optical measurement components and cuvette transfer components etc., while the operations of loading and transferring cuvettes, dispensing sample reagents, mixing, cleaning, and photometry are performed in an assembly line, and many operations need to share some components, which makes it difficult to break through the limitation of test speed and the actual test throughput. Relatively low, not enough to meet the testing needs of hospitals and other related institutions in the future, so the hospital must purchase multiple instruments to use at the same time, not only occupying the test area, but also requiring multiple people to operate and maintain, resulting in cumbersome operation procedures and waste of resources
