A fully automatic photochemiluminescence detector

Abstract

The present invention proposes a fully automatic photochemiluminescence detector that improves the accuracy of chemical analysis, including a sample injection module, a sample loading arm module, an incubation tray module, a reagent tray module, and a reagent arm module. The sample loading arm module will be transferred to the reaction cup located on the incubation tray module. After the reaction cup rotates to the designated position with the incubation tray, the reagent arm module will transfer the reagents in the reagent tray module to the reaction cup. The samples in the reaction cup and After the reagents are mixed and incubated in the incubation plate, they are transferred to the detection module for light excitation and the luminescent signal generated after excitation is detected. The whole operation of the fully automatic photochemiluminescence detector of the present invention is automatic operation, which can effectively avoid the problems of uncertainty such as individual differences, manual errors, and operation specifications in manual operations, and improve the accuracy of chemiluminescence immunoassay.

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 available 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 b...
