Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fully automatic chemiluminescence immunoassay analyzer. Background technique [0002] Chemiluminescence immunoassay (CLIA for short) is a non-radioactive immunoassay technology that is developing very rapidly in the world. It has the advantages of high sensitivity, strong specificity, wide linear range, and high degree of automation. primary means. [0003] Most of the automatic chemiluminescence analyzers currently on the market are generally composed of a manipulator or a chain transmission mechanism, a reagent sample part, an incubation part, a cleaning part, and a luminescence detection structure. During the detection process, generally, the reagent tube is added with samples, magnetic beads, and reagents. After the incubation is completed, the sample reaction tube is clamped and transferred to the cleaning position by the robot for magnetic separation, cleaning, m...

AI Technical Summary

Problems solved by technology

Among them, the cleaning of the reagent tube and the mixing process of the reagent have the most direct impact on the luminescence effect. Incomplete cleaning and mixing will often cause problems such as unstable luminescence effect and distortion of test results.

A detection process requires the robot to grasp the reaction tube for multiple transfer operations. During the transfer process, the sample reaction tube often has problems such as excessive loss of temperature and energy and incomplete reaction, and may even miss the best timing for luminescence detection, causing test results Large errors or unstable test results; in addition, too many grasping and placing actions of reaction tubes may easily lead to problems of reduced test reliability and test efficiency
