Novel magnetic separation mechanism

Abstract

The invention discloses a novel magnetic separation mechanism. The novel magnetic separation mechanism comprises a coding turntable mechanism, a magnet opening and closing mechanism and washing mechanisms, wherein the magnet opening and closing mechanism is mounted on the coding turntable mechanism; the washing mechanisms are distributed at the periphery of the coding turntable mechanism; the magnet opening and closing mechanism is used for controlling a magnet to adsorb nano magnetic beads in liquid of a reaction cup on the coding turntable mechanism; the washing mechanisms are used for washing the liquid in the reaction cup to separate the nano magnetic beads. By virtue of the novel magnetic separation mechanism, multi-station separation and washing are carried out by the same mechanism; a uniform mixing station is arranged; the action process of one station and the action processes of other stations can be simultaneously carried out; a magnetic particle mixing mechanism does not need to be arranged outside the mechanism; by virtue of the rotation movement of the coding turntable plate, the magnetic particles can be uniformly mixed according to the principle of the cam movement and the principle of eccentric rotation, so that the action processes are achieved; the novel magnetic separation mechanism is simple in structure; and the separation and washing efficiency of the device is improved.

Description

technical field [0001] The invention relates to a novel magnetic separation mechanism. Background technique [0002] With the development of magnetic particle technology, chemiluminescence immunoassay technology has been more and more widely used in the medical industry. During the testing process of the fully automatic chemiluminescence immunoassay equipment, nano magnetic beads need to be combined with antibodies and antigens, and the remaining liquid in the cuvette needs to be cleaned after the nano magnetic beads are combined with antibodies and antigens. At present, in order to realize simultaneous processing of multiple samples or reduce the waiting time for single sample separation and washing, most magnetic separation and cleaning mechanisms in automatic chemiluminescence instruments linearly distribute multiple identical units; in order to perform secondary or multiple incubations, outside the mechanism A magnetic particle mixing mechanism is provided, which length...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that it is impossible to realize multi-station separation and washing in the same mechanism and a mixing station is provided. When performing the action flow of a certain station, the action flow of other stations cannot be carried out at the same time. The problem of the magnetic particle mixing mechanism outside the mechanism is solved by using a new type of magnetic separation mechanism proposed, which has a simple structure and improves the separation and washing efficiency of the equipment
