Automatic photo-stimulated chemiluminescence detector

Abstract

The invention provides an automatic photo-stimulated chemiluminescence detector which can enhance the accuracy of chemical analysis. The detector includes a sample introduction module, a sample addingarm module, an incubating tray module, a reagent disk module and a reagent arm module; a sample in the sample introduction module is transferred into a reaction cup located on the incubating tray module through the sample adding arm module; the reagent arm module transfers a reagent in the reagent disk module into the reaction cup after the reaction cup rotates to a specified location with incubating trays; and the sample and reagent in the reaction cup are transferred to a detection module to perform light excitation after the mixing and incubating in the incubating trays are finished, and detection is performed on a luminous signal generated after excitation. The whole operation of the detector is automatic operation, so that the uncertainty problems of individual difference, artificialerrors and operating specifications of manual operation can be effectively avoided, and therefore, the accuracy of chemiluminescence immunoassay can be enhanced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a fully automatic photochemiluminescence detector. Background technique [0002] Currently existing photochemiluminescence analyzers are generally used to read 96-well or 48-well microplates; or 8-well microwell strips. The so-called 96-well, 48-well and 8-well means that the plate includes 96 or 48 or 8 cuvettes. Each sample to be tested is placed in a cuvette, and when the number of samples to be tested is one, a whole 96-well, 48-well or 8-well microplate should also be used. So a lot of waste is caused. And the time required for 96 holes, 48 ​​holes, and 8 holes is inconsistent, so it has a certain impact on the consistency of the results. [0003] In addition, there is a "HOOK" effect in the immune response, and the instrument did not have a secondary reading function before. It is impossible to avoid the phenomenon of false positive detection results caused by...
