Micro carrier cleaning device

Abstract

The invention discloses a microcarrier cleaning device, which comprises a sample plate, a reaction plate frame, a microcarrier adsorption device and a cleaning device. The sample plate is provided with a plurality of reaction cups arranged at intervals with the mouths facing upwards. There are mounting holes for placing the sample disk, and the microcarrier adsorption device is arranged under the reaction disk rack. The microcarrier adsorption device includes a substrate and a plurality of magnets arranged on the substrate, and the plurality of magnets are respectively arranged corresponding to a plurality of reaction cups , the cleaning device is arranged above the reaction tray rack. The sample plate is installed on the mounting hole of the reaction plate rack, and the cleaning device located above the reaction plate rack can clean the reaction cups. Since it is no longer necessary to set the reaction cups on the rotating disc, it effectively avoids the need for reaction cups. Cross-contamination caused by spinning. The microcarrier adsorption device is arranged under the reaction plate rack, and the microcarriers will be adsorbed by the magnet to the bottom of the reaction cup during cleaning. The adsorption force is better, the microcarriers are not easy to be lost, and the cleaning is more sufficient.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a microcarrier cleaning device. Background technique [0002] Chemiluminescence immunoassay technology is widely used in medical and scientific research fields because of its short reaction time and simple operation, which greatly improves the work efficiency of immunodiagnosis. The chemiluminescent immunoassay analyzer is an instrument used to measure the chemical composition of body fluids. It is currently widely used in hospitals and epidemic prevention stations at all levels. [0003] The chemiluminescence immunoassay analyzer uses microcarriers as the reaction carrier, and a single sample can perform multiple tests at the same time with only a small amount of samples, which can provide clinically more accurate, simple, fast and cost-effective disease screening and diagnosis services. The chemiluminescent immunoassay analyzers currently on the market are usually equipped with ...

AI Technical Summary

Problems solved by technology

[0005] 1) Multiple adjacent cuvettes are set on the rotary rotating disc, and the poor stability during rotation may easily cause cross-contamination;

[0006] 2) The microcarriers are adsorbed on one side by the microcarrier adsorption device during cleaning, the microcarriers are easily lost due to insufficient adsorption force, and the cleaning is not sufficient
