Embodiment
[0031] This embodiment provides a magnetic cleaning and separation device for an immune analyzer, such as figure 1 As shown, it includes a cuvette transport assembly 1, a cleaning needle assembly 2, a magnet assembly 3 and a cleaning position 4;
[0032] The cuvette conveying assembly 1 is used to convey the cuvettes 5 to different cleaning positions 4. Specifically, the cuvette conveying assembly 1 includes a fixed part and a moving part. An accommodating part for accommodating the cuvette 5 is arranged on the part, and the moving part can carry the cuvette 5 to move in the cuvette running groove;
[0033] The cleaning needle assembly 2 is used to inject the cleaning liquid into the cuvette 5 in the cleaning position 4 and draw the cleaning liquid from the cuvette 5. It is preferable to set a corresponding cleaning needle assembly 2 corresponding to each cleaning station 4, so that The cleaning needle assemblies 2 can work at the same time, improving the cleaning efficiency;...

Abstract
The invention relates to a magnetic cleaning and separating device of an immunity analyzer. The magnetic cleaning and separating device of the immunity analyzer comprises a reaction cup conveying assembly, a cleaning needle assembly, a magnet body assembly and a plurality of cleaning positions, wherein the magnet body assembly comprises two oppositely-arranged magnet body pairs arranged on the twosides of an operation path of a reaction cup correspondingly and single magnet bodies arranged on one side of the operation path of the reaction cup; and the magnet body pairs correspond to the cleaning positions, the single magnet bodies are located between the cleaning positions or located in front of the first cleaning position in the operation path direction of the reaction cup, at least onemagnet body is arranged between the every two adjacent cleaning positions or located at the position, in front of the first cleaning position in the operation path direction of the reaction cup, of each side of the operation path of the reaction cup, the magnet bodies, located between the cleaning positions or located in front of the first cleaning position in the operation path direction of the reaction cup, are alternately arranged on the two sides of the operation path of the reaction cup correspondingly, and the directions of magnetic poles of every two adjacent magnet bodies are opposite.According to the magnetic cleaning and separating device, the magnetic separation time is extremely short, the purpose of fully cleaning magnetic beads is achieved, and the magnetic beads can be effectively prevented from being sucked by cleaning needles.
Description
technical field [0001] The application belongs to the technical field of medical devices, and in particular relates to a magnetic cleaning and separation device for an immune analyzer. Background technique [0002] In the automatic immunoassay system, the effective separation of immune complexes is the key link of immunoassay, and the separation effect directly affects the results of immunoassay. At present, in the immunoanalyzer using magnetic beads as the reaction carrier, the separation of immune complexes mainly adopts the magnetic separation method. After specific binding, the reactants (immune complexes) bound to the magnetic beads are retained by means of an external magnetic field, and the excess reactants and reagents are separated. The time in the whole magnetic separation process of the magnetic separation method can be very short, but the existing magnetic cleaning separation device of the immune analyzer has a poor washing effect on the immune complex.
