Embodiment Construction

[0029] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] as attached Figure 1-4 As shown, a magnetic separation device according to the present invention includes a cleaning turntable mechanism, a magnet structure, a mixing mechanism, and a cleaning needle mechanism. The cleaning turntable mechanism, mixing mechanism, and cleaning needle mechanism are all connected to the controller 11. The controller 11 adopts STM32F103VET6, and controls the operating states of the revolution stepping motor 28, the rotation stepping motor 44, and the cleaning needle stepping motor 58 through the controller 11.

[0031]The cleaning turntable mechanism includes a bottom plate 21, a cleaning turntable 22, a self-rotating assembly 23, a rotating shaft 24, a bearing seat 241, a revolution synchronous belt driven wheel 25, a revolution synchronous belt 26, a revolution synchronous belt driving wheel 2...

Abstract

The invention relates to a magnetism separating device. The magnetism separating device comprises a cleaning turnplate mechanism, a magnet structure, a mixing mechanism and a cleaning needle mechanism, and the cleaning turnplate mechanism, the mixing mechanism and the cleaning needle mechanism are all connected with a controller. The magnetism separating device has the advantages that the magnet structure is fixedly located on the inner side face of a reaction cup, and the adsorption area and the adsorption time of a magnet block can be guaranteed through the adsorption position of the magnet structure; the mixing mechanism is synchronously driven by a rotation stepping motor and a rotation synchronous belt, synchronous rotation mixing of cleaning fluid in the multiple reaction cups can be achieved, and the washing efficiency is improved greatly; under the condition that the cleaning effect is guaranteed, the magnetism separating device accelerates the detecting speed, simplifies the instrument structure and has broad prospects.

Description

technical field [0001] The invention relates to the technical field of magnetic separation, in particular to a magnetic separation device based on chemiluminescence immunoassay technology. Background technique [0002] Luminescence immunoassay is a new type of ultra-trace analysis technology established by combining luminescence analysis and immune reaction. This technology uses a chemical or bioluminescent system as an indicator system for antigen-antibody reactions to quantitatively detect antigens or antibodies. This method has both the high sensitivity of luminescence analysis and the high specificity of antigen-antibody reaction. [0003] At present, chemiluminescent immunoassay technology has been widely used in the field of in vitro diagnosis due to its stable, fast and accurate characteristics. The automatic chemiluminescent immunoassay analyzer needs to specifically bind the magnetic beads to the target substance in the sample, and then make the magnetic beads gat...
