Abstract

A full-automatic chemiluminescence immune analyzer magnetic bead washing device comprises a reaction cup rotation disc, a lifting needle support, a magnetic bead absorbing device and mixing devices. The lifting needle support is driven by a lead screw motor to move vertically along a linear sliding track. An eight-washing-needle assembly is arranged on the lifting needle support, four needles are liquid injecting needles and used for injecting washing liquid into a reaction cup, and other four needles are liquid sucking needles and used for sucking waste liquid in the reaction cup. The eight washing needles conduct washing liquid injection movement and waste liquid sucking movement on the reaction cup sequentially, and once diluting and three-time washing are conducted on magnetic beads in the reaction cup. An annular magnetic bead absorbing device is arranged below the inner side of the reaction cup rotation disc, and the plurality of mixing devices are arranged above two sides of the reaction cup rotation disc respectively. By means of the device, assembly line type washing of the magnetic beads is achieved, washing is thorough, magnetic bead loss is smaller, structure is optimized, control is simple, relatively independent functions are achieved, and the device is suitable for a whole automatic system.

Description

technical field [0001] The invention relates to a full-automatic chemiluminescence immune detection system or instrument, in particular to a magnetic bead cleaning device for a full-automatic chemiluminescence immune analyzer. 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. Magnetic bead washing is not a reaction step in the CLIA process, but it is the key to the success of the experiment. The purpose of washing is to wash away the substances in the reaction solution that are not bound to the solid-phase antigen and antibody, as well as the interfering substances that are no...
