Description

Technical Field

[0001] The present invention relates to the technical field of protein analysis devices, and in particular to a fully automatic specific protein analysis device. Background Art

[0002] C-reaction protein (CRP) is a stress protein in the human body that can react with the formulated reagents to form an immune complex reaction. The concentration of specific proteins contained in the sample can be determined by immunoassay. Currently, most of the devices on the market for detecting specific proteins are based on manually replacing the reaction vessels, with single functions. The reactor and the detection device need to be manually separated and the reactor is a disposable product that needs to be treated at high temperature for harmlessness. The pollutants generated during the treatment process put great pressure on the environment, and the treatment of pollutants greatly increases the cost of detection. In addition, the existing specific protein reaction devices are large in size and difficult to install and use with other equipment. The reaction cup body is difficult to maintain or uses a disposable cup body. The detection element has low signal energy utilization, and light leakage poses a safety hazard.
