[0002] Luminescent magnetic beads are a kind of biosensor material used for diagnostic testing, which has high sensitivity and specificity. By measuring the content of specific molecules in the sample or the presence of specific bacteria and viruses to diagnose diseases, luminescent magnetic beads are widely used in clinical diagnosis, biomedical research, environmental monitoring and other fields. They are fast, sensitive and high-throughput, which can greatly improve the efficiency and accuracy of detection. When using luminescent magnetic beads, they need to be mixed by a mixing device. There are at least the following disadvantages in the use of existing luminescent magnetic bead mixing devices: Most of the existing mixing devices are mixed by setting a stirring rod with a stirring blade, but the stirring blade is large in size during use, resulting in a small amount of magnetic beads. The small size of the stirring blade leads to insufficient mixing, which is not conducive to use. Therefore, we introduce a diagnostic test reagent luminescent magnetic bead mixing device.
