Fully-automatic light initiated chemiluminescence detector

Abstract

The invention provides a fully-automatic light initiated chemiluminescence detector for improving the accuracy of chemical analysis. The fully-automatic light initiated chemiluminescence detector comprises a plate taking rack module, a pushing device, a sample adding arm module, a rotating disc module, a sample rack module, an incubation module, a reagent module and a detection module, wherein a lath on the plate taking rack module is pushed to the rotating disc module through the pushing device, a sample and a reagent are added into a reaction cup on the lath positioned on the rotating disc module through the sample adding arm module, and the lath on the rotating disc module is pushed into the incubation module through the pushing mechanism, is incubated, enters the detection module, andis detected. The fully-automatic light initiated chemiluminescence detector has the advantages of simple structure, smooth and simple detection flow, high detection efficiency and high detection accuracy.

[0004] At present, the existing photochemiluminescence detectors are generally used to read 96-well or 48-well microplates. The so-called 96-well or 48-well microplates include 96 or 48 cuvettes on the plate, each of which needs to be detected The samples are placed in one cuvette, and when the number of samples to be detected is only a few or a dozen, it is also necessary to use a whole piece of 96-well or 48-well microplate, thus causing a lot of waste, and the 96-well or 48-well microplate It takes a long time for the microplate to add samples from the first well to the last well, so it has a certain impact on the consistency of the results. For example, the authorization announcement number published on March 19, 2014 is CN203490229U The patent disclosed a quasi-automatic plate-type immunoassay analyzer, which is mainly composed of a box body, a placement unit, an incubation unit, a cleaning unit, a substrate filling unit, an optical detection unit and a system operation control unit, and realizes reaction solution incubation 1. The whole process of reaction liquid washing plate, reaction liquid self-injection and substrate measurement, two microwell plates can be placed at the same time during operation

On the other hand, the existing single cuvette on the market is used as a transfer and detection unit, and it can also detect when there is only one sample. However, the efficiency of this single detection is not high enough, and when the number of samples is large, the detection time is relatively short. Long, not suitable for mass inspection, for example, in the patent of CN102183639B published on June 5, 2013, a fully automatic chemiluminescence immunoassay analyzer is disclosed, which consists of a cuvette feeding system, a three-dimensional moving The sample addition module, sample area, reagent area, pump group, and control system are composed of a single cuvette for transfer detection, so the detection efficiency is not high enough

[0005] Both of the above two detection methods have their own disadvantages, and there is an urgent need for a photochemiluminescence detector between the above two, which needs to ensure the accuracy of the results and the efficiency of the detection
