A reagent disk magnetic bead mixing device and its application method

Abstract

The invention provides a reagent disk magnetic bead mixing device and its use method, comprising an outer disk, the bottom of the outer disk is provided with a first gear, the upper part of the outer disk is provided with a plurality of mixing seats, and the mixing seats are connected with A second gear, the second gear meshes with the first gear, the first gear meshes with a third gear, and the third gear is connected with the first driving device. The first driving device drives the third gear to rotate, the third gear drives the first gear to rotate, the first gear drives the mixing seat to rotate, and the mixing seat contains reagents mixed with magnetic beads. When the magnetic beads need to be mixed, Just turn on the first driving device, and the mixing seat will rotate independently to mix the magnetic beads. By using the first gear to drive multiple second gears to rotate at the same time, it drives the mixing seat to rotate to realize the mixing of magnetic beads, without relying on the rotation of the outer disk to achieve the mixing of magnetic beads, which shortens the experiment time and reduces the rotation of the outer disk , thereby reducing the wear of various components.

Description

technical field [0001] The invention relates to the technical field of automatic magnetic particle chemiluminescence immunoassay analyzer equipment, in particular to a reagent disk magnetic bead mixing device and a use method. Background technique [0002] Reagent mixing is an important breakthrough in the field of medical detection technology and an important part of the stability of chemiluminescence instruments. The quality of magnetic bead mixing will directly affect the experimental results. In the previous design, the magnetic bead mixing gear was fixedly installed, which required the entire reagent outer disk assembly to rotate back and forth to drive the magnetic bead mixing seat to rotate and mix the magnetic beads. When the sample is loaded, the outer ring assembly of the reagent tray has not been turned to the corresponding position. At this time, the reagent arm should wait for the outer ring assembly of the reagent tray to turn to the correct position, and then ...

AI Technical Summary

Problems solved by technology

In the previous design, the magnetic bead mixing large gear was fixed and installed, which required the entire reagent outer disk assembly to rotate back and forth to drive the magnetic bead mixing seat to rotate the mixing magnetic beads. This would cause that if the reagent arm rotated to the required When the sample is added, the outer ring assembly of the reagent tray has not turned to the corresponding position. At this time, the reagent arm must wait for the outer ring assembly of the reagent tray to turn to the correct position, and the reagent arm goes down to add samples, which will cause: 1. Every time the magnetic beads are mixed, the reagent plate needs to be rotated back and forth, and then returned to the reagent loading position, which will cause a long delay in the mixing of the magnetic beads, and will cause the luminometer reagent plate to over-period alarm and terminate the experiment. ;2. It is not conducive to shortening the experiment time of the entire luminometer in the later stage. The highlight of the luminometer is the fast and accurate results; 3. The moving parts of the reagent plate are severely worn and the service life is reduced; The scanning code does not recognize the phenomenon, the magnetic beads are in the middle circle, and the inner circle is blocked by reagent bottles with other components, which will cause the code scanning success rate to be too low
