Abstract
(EN)
Disclosed is a magnetic cleaning and separating device of an immunity analyzer. The device comprises a reaction cup conveying assembly (1), a cleaning needle assembly (2), a magnet assembly (3) and several cleaning stations (4). The magnet assembly comprises two magnet pairs arranged opposite each other on two sides of a running path of a reaction cup, and individual magnets arranged on one side of the running path of the reaction cup (5); the magnet pairs correspond to the cleaning stations; the individual magnets are located between the cleaning stations or located in front of the first cleaning station in the direction of the running path of the reaction cup; at least one magnet is arranged on each side of the running path of the reaction cup, and between the cleaning stations or in front of the first cleaning station in the direction of the running path of the reaction cup; and the magnets, between the cleaning stations or located in front of the first cleaning station in the direction of the running path of the reaction cup, are alternately arranged on the two sides of the running path of the reaction cup, and the directions of magnetic poles of two adjacent magnets are opposite. The magnetic separation time of the magnetic cleaning and separating device is extremely short, such that the aim of fully cleaning magnetic beads is achieved, and cleaning needles can be effectively prevented from attracting the magnetic beads.

La présente invention concerne un dispositif de nettoyage et de séparation magnétique d'un analyseur d'immunité. Le dispositif comprend un ensemble de transport de coupelle de réaction (1), un ensemble aiguille de nettoyage (2), un ensemble aimant (3) et plusieurs stations de nettoyage (4). L'ensemble aimant comprend deux paires d'aimants disposées l'une en face de l'autre sur deux côtés d'un trajet de déplacement d'une coupelle de réaction, et des aimants individuels disposés sur un côté du trajet de déplacement de la coupelle de réaction (5) ; les paires d'aimants correspondent aux stations de nettoyage ; les aimants individuels sont situés entre les stations de nettoyage ou situés devant la première station de nettoyage dans la direction du trajet de déplacement de la coupelle de réaction ; au moins un aimant est disposé de chaque côté du trajet de déplacement de la coupelle de réaction, et entre les stations de nettoyage ou devant la première station de nettoyage dans la direction du trajet de déplacement de la coupelle de réaction ; et les aimants, entre les stations de nettoyage ou situés devant la première station de nettoyage dans la direction du trajet de déplacement de la coupelle de réaction, sont disposés en alternance sur les deux côtés du trajet de déplacement de la coupelle de réaction, et les directions des pôles magnétiques de deux aimants adjacents sont opposées. Le temps de séparation magnétique du dispositif de nettoyage et de séparation magnétique est extrêmement court, de telle sorte que le but de nettoyage complet de billes magnétiques est obtenu, et des aiguilles de nettoyage peuvent être efficacement empêchées d'attirer les billes magnétiques.
