Analyzer magnetic ball cleaning device

Abstract

The invention relates to an analyzer magnetic ball cleaning device. The analyzer magnetic ball cleaning device comprises a basal body module, an uniform mixing module, a rotating module, a lotion injecting module and a waste liquid sucking module; the basal body module comprises a base plate, a bearing base, a rotating base shaft, a rotating motor and an uniform mixing lifting guide shaft; the uniform mixing module comprises an uniform mixing disc, an uniform mixing position, an uniform mixing screw motor and an uniform mixing rotating motor; the rotating module comprises a rotating disc and an eccentric rotating cup support; the lotion injecting module comprises an injecting fixed plate, a lotion needle, a lotion injecting bracket, a primer needle, an injecting needle frame, a support column and a magnet frame; and the waste liquid sucking module comprises a linear guide rail, a support stand plate, a guide rail transfer frame, a sucking screw motor, a reinforcing rib, a waste liquidsucking bracket and multiple waste liquid sucking needle units. The analyzer magnetic ball cleaning device uses multiple needles for injecting lotion and sucking waste liquid and multiple positions for eccentric rotary uniform mixing to achieve good cleaning effect, high instrument throughput, low cost and low fault rate.

Description

technical field [0001] The invention relates to an analyzer magnetic bead cleaning device, which belongs to the technical field of medical instruments. Background technique [0002] Chemiluminescence immunoassay (CLIA) is a method for immunological quantitative analysis of patient body fluid samples, used to test various antigens, haptens, antibodies, hormones, enzymes, fatty acids, vitamins and drugs, etc. It has the advantages of high sensitivity, wide linear range, simple equipment, convenient operation, fast detection speed, process automation, etc. It can greatly improve the efficiency of immunoassay, so it is widely used in modern clinical immunoassay diagnosis and life optional research fields . Combining highly sensitive chemiluminescent assay technology with highly specific immune responses. It is usually necessary to coat specific biological materials on magnetic beads, carry out a series of immune reactions with the analytes through antigens or antibodies, wash ...

AI Technical Summary

Problems solved by technology

[0003] The magnetic bead cleaning device of the analyzer is a device invented to achieve continuous measurement without interrupting the process. The cuvette is cleaned multiple times on the rotating disc to clean away the excess reagents that did not participate in the reaction, while ordinary The cleaning device generally cannot realize the continuous operation of continuous reaction cup cleaning operation, precise filling of lotion, eccentric mixing and rotation, magnetic bead adsorption, waste liquid suction, and substrate filling, thereby reducing the cleaning effect and operating efficiency. And achieve the characteristic functions of good cleaning effect, high instrument throughput, less execution power source, low cost and low failure rate
