Chemiluminescence immunoassay analyzer

Abstract

The invention discloses a chemiluminescence immunoassay analyzer. The analyzer comprises a turntable assembly used for carrying and insulating capillary tubes, a blowing assembly used for removing residual liquid in the capillary tubes, a detection assembly used for detecting the number of luminous photons of the capillary tubes, and a bottom plate for mounting the turntable assembly, the blowingassembly and the detection assembly. The analyzer also comprises a material pushing and recycling system and a sample feeding assembly. The material pushing and recycling system comprises a fixed seat, a capillary tube pushing device, a storage device, a first driving device and a waste liquid recycling device; the capillary tube pushing device is used for pushing out a capillary tube from the storage device and extruding out the reagent stored in the storage device; the storage device is used for storing a reagent and providing a coated capillary tube. According to the invention, the cooperation is precise, the installation of each station is more compact, the size of the analyzer is smaller, the occupied space is smaller, and the analyzer is more miniaturized; and the detection efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a chemiluminescence immunoassay analyzer, which belongs to an instrument for immunoassay using chemiluminescence, and belongs to the technical field of chemiluminescence analysis. Background technique [0002] ChemiLuminescence (CL for short) is a kind of molecular luminescence spectroscopic analysis method, which is mainly based on the principle that the concentration of the analyte in the chemical detection system and the chemiluminescence intensity of the system are linear and quantitative under certain conditions. A trace analysis method to determine the content of the analyte by using the instrument to detect the chemiluminescence intensity of the system. Chemiluminescence has been widely used in the analysis of trace metal ions, various inorganic compounds, organic compounds and biological fields. [0003] Chemiluminescence immunoassay (CLIA) is a combination of high-sensitivity chemiluminescence assay technology and hig...

AI Technical Summary

Problems solved by technology

[0006] 1. There are many underutilized spaces inside the analyzer, and the positions of each station are relatively scattered, and the number of stations is large, resulting in the overall volume of the analyzer being too large;

[0007] 2. When sending blood samples, the number of samples sent is small, and it is impossible to follow up with the inspection, and it is necessary to wait;

[0008] 3. When the capillary is pushed out, when the capillary mechanism is pushed out and the capillary storage component is positioned, it will collide with the capillary storage component. After using it for many times, the position accuracy of each component may be affected, resulting in internal failure of the analyzer;

[0009] 4. The capillary storage component is always connected with the inside of the analyzer. During use, dust may enter the analyzer, and the cleanliness of the capillary will be affected, resulting in errors in the test results.
