Abstract

The invention relates to a magnet-unilateral-distributed magnetic washing separation mechanism of an analyzer. The mechanism comprises a first magnet set, a second magnet set and a third magnet set which are arranged sequentially and are located at the same side of a conveying belt direction of a reaction cup conveying assembly and are arranged along the conveying belt direction of the reaction cup conveying assembly. The three magnet sets are provided with reasonable magnet arrangement and magnetic pole distribution, thus, magnetic beads can be adsorbed to cup walls of reaction cups or rotate in the reaction cups, uncombined substances wrapped in a combination can be released during the washing of the magnetic beads, a part of reactants combined with the magnetic beads are better reserved, the time for a whole magnetic separation process can be as short as possible, finally, the magnetic beads in the cups can fully react with a substrate after the reaction cups enter a measurement room, and a substrate solution is saved.

Description

Technical field [0001] The invention relates to a magnetic cleaning and separating mechanism for an analyzer with magnets arranged on one side, and belongs to the technical field of medical equipment. Background technique [0002] Chemiluminescence immunoassay is becoming the most important method of in vitro immunoassay. The effective separation of immune complexes is the key link of chemiluminescence immunoassay, and the separation effect directly affects the results of immunoassay. In the automatic immunoassay system, the currently used immune complex separation methods mainly include centrifugal separation, fiber mesh separation and magnetic separation. The main disadvantage of centrifugal separation is that it is easy to cause loss of compound or residue of impurities. The disadvantage of fiber mesh separation is that when the concentration of compound is too large, it is easy to cause partial blockage of the mesh and affect the passage of impurities. Magnetic separation tec...
