Washing module of full-automatic chemiluminescence immunoassay analyzer

Abstract

The invention discloses a washing module of a full-automatic chemiluminescence immunoassay analyzer. The washing module comprises a base, wherein a cavity is formed in the upper end of the base; the supporting disc is rotationally mounted in the cavity, and supporting holes are distributed in the supporting disc in a circumferential array manner and are used for vertically mounting reaction cups; the shaking-up mechanism is arranged below one of the supporting holes in a manner of moving up and down through a lifting assembly; the magnetic blocks are fixedly embedded in the base, the magnetic blocks are uniformly distributed in an array mode in the circumferential direction where the supporting disc is located, and the heights of the magnetic blocks are gradually reduced in the circumferential direction of the supporting disc; the driving mechanism is mounted at the bottom of the base and used for driving the supporting disc to rotate; and the liquid supplying and taking system is positioned above the base and is used for injecting liquid into the reaction cup or extracting waste liquid. The reaction cup washing device has the beneficial effects that operations such as shaking up, cleaning liquid filling, waste liquid extraction and substrate filling on different reaction cups can be synchronously realized, the washing efficiency is higher, and the product structure is more compact.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a washing module of an automatic chemiluminescence immunoassay analyzer. Background technique [0002] Chemiluminescence immunoassay is an emerging analytical method that combines magnetic separation technology, chemiluminescence technology and immunoassay technology. Using suspended magnetic particles as a carrier, with its unique 3D surface and high specific surface area, provides sufficient contact area and high sensitivity for capturing target molecules. At the same time, the superparamagnetic properties of the magnetic particles can realize multiple magnetic separations, which is conducive to speeding up the detection speed and the full automation of the instrument. Therefore, the magnetic particle chemical immunoassay method has been widely used in the field of biomedical detection due to its unique advantages. [0003] In the physical structure of the chemilumi...
