Description

technical field [0001] The invention relates to a small automatic chemiluminescent immunoassay system. Background technique [0002] At present, there are fully automatic chemiluminescence immunoassay systems and semi-automatic chemiluminescence immunoassay systems for chemiluminescence immunoassays on the market. A fully automatic chemiluminescence immunoassay system generally consists of a cuvette feeding system, sample loading system, reagents The sample adding system, the sample storage area, the reagent storage area, the incubation reaction system, the magnetic separation cleaning system, the chemiluminescence measurement system and the computer control system are composed. Mechanism, and cuvette position detection device, sample sampling system and reagent sampling system mainly include two sample loading arms driven by stepping motors, two high-precision metering pumps and corresponding connecting pipelines, two loading arms The sample arms are all controlled by a co...

Problems solved by technology

Its characteristic is that the entire chemiluminescence immunoassay process can be automatically processed from cuvette feeding, sample addition, reagent addition, incubation, cleaning to chemiluminescence measurement, without manual operation, with large processing capacity, time-saving, fast and efficient , high degree of automation, suitable for large hospitals with a large amount of sample processing, but the cost of a fully automatic chemiluminescence immunoassay system is extremely expensive, for small hospitals and social health centers with a small amount of daily analysis, high equipment costs make it impossible to be practically applied

[0003] The existing semi-automatic chemiluminescence immunoassay system, as a simplified chemiluminescence immunoassay instrument, omits the cuvette feed processing system, incubation reaction system, magnetic separation cleaning system, etc., and only retains the chemiluminescence measurement system and In contrast, the design of the control system and mechanical structure of the control system is relatively simple, which greatly reduces the cost. However, since the steps of sample addition, reagent addition, incubation reaction, and cleaning steps of chemiluminescence immunoassay are all completed by manual operation, The operator needs to manually record the sample addition time and incubation reaction time of each sample, and accurately control the sample, reagent addition sequence and incubation reaction time. When it is used, it is easy to make operation errors, which will affect the accuracy of the results of chemiluminescence immunoassay, so there is a defect of low safety.
