Abstract

The invention discloses a magnetic cleaning and separating device, a magnetic cleaning and separating control method and sample detection equipment, the magnetic cleaning and separating device is provided with at least one cup grabbing station and at least one cleaning station, and the magnetic cleaning and separating device comprises a magnetic separating disc, an annular magnet, a cup grabbing assembly, a cleaning assembly and a controller; the magnetic separating disc is used for accommodating a sample container; the annular magnet is arranged on the magnetic separating disc so that the magnetic carrier in the sample container is attached to the inner wall of the sample container under the adsorption action of the annular magnet; the controller is connected with the magnetic separating disc, the cup grabbing assembly and the cleaning assembly, and the controller is used for driving the magnetic separating disc to rotate, controlling the cup grabbing assembly to place the sample containers in the magnetic separating disc or take the sample container out of the magnetic separation disc and when the sample container rotates to the cleaning station, controlling the cleaning assembly to clean the reactants in the sample container. In this way, the cleaning efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of sample detection, in particular to a magnetic cleaning and separation device, a control method for magnetic cleaning and separation, and a sample detection device. Background technique [0002] In the field of sample detection technology, especially in the immunoassay system, the effective separation of immune complexes is a key link in immunoassays, and the separation effect directly affects the results of immunoassays. [0003] In the immune analyzer using magnetic beads as the reaction carrier, the separation of immune complexes mainly adopts the magnetic separation method. Combine, and then retain the reactants (immune complexes) bound to the magnetic beads with the help of an external magnetic field, and separate the excess reactants and reagents. [0004] At present, the existing magnetic cleaning and separation devices are not effective in washing the residual liquid (ie excess reactants...
