A fully automatic chemiluminescence immunoassay analyzer and its fluid system

Abstract

The invention discloses a fully automated chemiluminescence immunity analyzer and a liquid path system thereof. A sample and luminescent acid and base solutions are picked up and fed by a plunger pump and a solenoid valve, the inner wall of a sample needle is cleaned through a cleaning liquid, a reagent is picked up and fed by injection syringes and a solenoid valve, the concentrated cleaning liquid is prepared and diluted through the two injection syringes, the outer wall of the sample needle and the inner and outer wall of a reagent needle are cleaned through the two injection syringes, a peristaltic pump treats a waste liquid of magnetic bead cleaning module cleaning, and a waste liquid diaphragm pump treats a waste liquid of the system and condensate water produced by a reagent refrigeration bin. The liquid path system of the fully automated chemiluminescence immunity analyzer realizes good balance of functions, maintenance and cost, and effectively solves the problems of cross-contamination of the liquid system, the waste of the system liquid, the high cost of the liquid path system, poor maintenance of the liquid path system, a single function of the liquid path system module, and the low utilization rate of various components.

Description

technical field [0001] The invention relates to the technical field of chemiluminescence detection analyzers, in particular to a fully automatic chemiluminescence immunoassay analyzer and its liquid path system. Background technique [0002] Chemiluminescent immunoassay is one of the mainstream research directions in clinical testing at present. It has the characteristics of high sensitivity, strong specificity, wide linear range, easy operation, and does not require very expensive equipment. [0003] Chemiluminescence immunoassay includes two systems: immunoassay and chemiluminescence analysis: the immunoassay system uses chemiluminescent substances or enzymes as markers, directly marks on antigens or antibodies, and forms antigen-antibody immune complexes through the reaction of antigens and antibodies; The chemiluminescent analysis system is to add oxidant or enzyme luminescent acid-base solution after the immune reaction is over. After the chemiluminescent substance is o...
