Description

technical field [0001] The invention relates to a biological body fluid or blood sample analysis device, in particular to a small electrochemiluminescence immunoassay analyzer and an analysis method thereof. Background technique [0002] The electrochemiluminescence immunoassay analyzer is mainly used for the determination of analyte content in clinical blood and other body fluid samples. Chemiluminescence immunoassay (CLIA) is a technology developed worldwide in the past 20 years. Compared with radioimmunoassay (RIA), enzyme immunoassay (EIA), fluorescence immunoassay (FIA) and other immunoassay techniques, it is environmentally friendly, Not affected by temperature and pH, long shelf life of reagents, high accuracy and sensitivity, etc. Therefore, chemiluminescent immunoassay is widely used in the field of in vitro diagnostics (IVD). [0003] There are many types of chemiluminescence immunoassays, such as direct chemiluminescence based on acridinium esters, indirect chem...

Problems solved by technology

This type of instrument saves the cost of the instrument and reduces the volume, but the process of adding samples, adding reagents, and incubating the reaction requires manual operation, which increases the complexity of the test, and when multiple samples are tested at the same time, it is easy to cause operational errors. Affect the accuracy of the test results, there are potential safety hazards

In addition, the existing full-automatic electrochemiluminescence analyzer has complex structure and large volume; the existing full-automatic electrochemiluminescence analyzer generally does not store the reagents at low temperature and cannot be placed for detection for a long time; the existing full-automatic electrochemiluminescence analyzer For automatic electrochemiluminescence analyzers, since the cuvette needs to be carried as a whole to its measuring device, it is inevitable to design the measuring device as an open module, so that external photons can easily enter the measuring device, and each time the cuvette enters The shape of the measuring device is different, which leads to the weak photon number obtained by the photomultiplier tube PMT used for reading during the measurement because it is easily affected by the entry of external photons, resulting in a large deviation, resulting in low measurement accuracy of the entire measurement system; Existing fully automatic electrochemiluminescence analyzers generally do not have a touch display unit, no human-computer interaction operating system, and the operation is not convenient enough
