Description

Technical Field

[0001] The utility model belongs to the technical field of chemiluminescent immunoassay analyzers, and more specifically, particularly relates to a reagent strip pushing device of a chemiluminescent immunoassay analyzer. Background Art

[0002] Chemiluminescent immunoassay (CLIA) is a non-radioactive immunoassay technology that has developed very rapidly worldwide in the past decade. It is an ultra-high sensitivity micro-determination technology developed after enzyme-linked immunosorbent assay (EIA), radioimmunoassay (RIA), and fluorescent immunoassay (FIA). Chemiluminescent immunoassay uses chemical or bioluminescent systems as indicator systems for antigen-antibody reactions to quantitatively detect antigens or antibodies. Chemical or bioluminescent substances can be directly used as markers for antigens or antibodies, or they can be used in free form in the luminescent reactions of catalyst-labeled and auxiliary-labeled antibodies or antigens. The free energy released by the chemiluminescent reaction excites the intermediates, causing the intermediates to return from the excited state to the ground state and release photons of the same energy level. The photons are then measured by the chemical immunoassay analyzer to accurately quantify the content of the substance being measured. The fully automatic chemiluminescent immunoassay technology combines classical methodology and advanced technology, and has outstanding advantages such as high sensitivity, high precision and accuracy, good reagent stability, and a high degree of automation.

[0003] At present, medical institutions in China use reaction cups or reaction cup strips to hold test samples during fully automatic chemiluminescence immunoassays. When the reaction cups or reaction cup strips are pushed to the darkroom for luminescence testing, mechanized operations have been realized, eliminating manual transfer operations and improving analysis efficiency. The cup delivery part, incubation part, washing part, and detection part of the fully automatic chemiluminescence immunoassay are closely coordinated, and the transfer and transportation process of the test samples between various systems is automatically completed. However, for chemiluminescence immunoassays with strip-shaped reagent reaction cups, the reagent strip of the strip-shaped reaction cup is longer, and the overall volume of the reagent strip composed of multiple reaction cups is larger than that of a single reaction cup. Therefore, the pushing mechanism for hooking the reagent strip to the darkroom needs to be improved. Therefore, we propose a reagent strip pushing device for a chemiluminescence immunoassay.
