Full automatic chemiluminescence immune assay instrument

Abstract

The invention discloses a full automatic chemiluminescence immune assay instrument. An upper needle plate group device, a photon detection device and a reagent strip propelling device are located above an upper plate; a specimen disc device and an incubation disc device are located below the upper plate; a dark room detection device is located in a region adjacent to the photon detection device and the reagent strip propelling device; a V-shaped notch slot is formed in a reagent putting station, corresponding to the incubation disc device, of the upper plate; both a puncture needle group device and an enhancing liquid needle group device in the upper plate needle group device are provided with a double needle structure which not only can move horizontally, but also can move vertically, and the other needle assemblies in the puncture needle group device and the enhancing liquid needle group device are stirring needle assemblies. As the station of the incubation disc device is of a reasonable layout structure and the double needle structure is combined in use, the automatic degree of the instrument is improved, and the whole instrument is simpler and more compact in structure; and moreover, the full automatic chemiluminescence immune assay instrument is low in cost and quite suitable for being popularized and generalized in medical units at home.

Description

technical field [0001] The invention relates to the field of chemiluminescence immunoassay equipment used in in vitro diagnosis and biomedicine, in particular to a fully automatic chemiluminescence immunoassay analyzer. Background technique [0002] Point of Care Testing (POCT) is an important development direction and the fastest growing field of the in vitro diagnostic industry in recent years. 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] Chemiluminescent immunoassay (CLIA, chemiluminescent immunoassay) is a combination of highly sensitive chemiluminescent assay technology and highly specific immune response, used in clinical laboratories and scientific research units for various antigens, haptens, antibodies, hormones , virus markers, tumor markers, enzymes, fatty acids, vita...

AI Technical Summary

Problems solved by technology

[0006] However, the research and development of CLIA in developed countries outside of China is relatively mature, while the research and development of CLIA in China has developed rapidly in recent years but is still in its infancy, and there is still a big difference between China and foreign countries. Nowadays, the automatic instruments for chemiluminescence immunoassays in China are basically monopolized by foreign companies, and the prices are relatively expensive. Therefore, it has become a major trend in China to independently develop a fully automatic chemiluminescence immunoassay.
