Abstract

The invention relates to a cleaning and separating device for a chemiluminescent analyser. The cleaning and separating device comprises a cleaning needle assembly, a cleaning needle assembly mountingframe for fixedly mounting the cleaning needle assembly, a cleaning needle assembly drive structure for enabling the cleaning needle assembly to move upwards or downwards, and a reaction cup conveyingassembly for moving a reaction cup to a position below the cleaning needle assembly, wherein the cleaning needle assembly comprises a needle tube fixed base, a waste liquor needle and a flushing needle, the waste liquor needle and the flushing needle are fixedly arranged on the needle tube fixed base; the bottom of the flushing needle is bent, and the bottom opening faces towards the outer wall of the waste liquor needle; spacing between the bottom opening of the flushing needle and the outer wall of the waste liquor needle is 1.2-1.8 mm; a perpendicular distance from the bottom opening of the flushing needle to the bottom opening of the waste liquor needle is 4-8 mm; and an included angle between the middle axis of the bottom opening of the flushing needle and the vertical direction is 125-145 degrees. When the flushing needle of the cleaning and separating device injects liquor, a liquor splashing phenomenon is avoided; and meanwhile, the purpose of flushing the outer wall of the waste liquor needle is achieved.

Description

technical field [0001] The invention relates to a cleaning and separating device for a chemiluminescence analyzer, which belongs to the technical field of medical instruments. Background technique [0002] Chemiluminescence analysis is the latest immunoassay technology developed after radioimmunoassay, fluorescence immunoassay, and enzyme immunoassay. It has the advantages of high sensitivity, wide detection range, and good stability of markers, and has become an important means of in vitro immunoassay. During the working process of the fully automatic chemiluminescence analyzer designed based on the principle of chemiluminescence, the cleaning and separation of reactants is a key link in immunoassay, and the cleaning effect has a great influence on the accuracy of the test results. [0003] At present, the cleaning and separation devices of chemiluminescence analyzers all have a cleaning needle structure. When the cuvette is driven in the cleaning area, the cleaning needle ...
