Uniform Mixing device for reagent tray magnetic beads as well as use method

Abstract

The invention provides a uniform mixing device for reagent tray magnetic beads as well as a use method. The device comprises an outer tray, wherein a first gear is arranged at the bottom of the outertray, a plurality of uniform mixing seats are arranged on the outer tray, second gears are connected with the uniform mixing seats, the second gears are meshed with the first gear, a third gear is meshed with the first gear, and a first driving device is connected with the third gear. The third gear is driven to rotate by the first driving device, the first gear is driven to rotate by the third gear, the uniform mixing seats are driven to rotate by the first gear, and a reagent mixed with magnetic beads is placed in the uniform mixing seats. When the magnetic beads are required to be uniformlymixed, only the first driving device is required to start, and the uniform mixing seats can rotate independently to uniformly mix the magnetic beads. The first gear drives the plurality of the secondgears to simultaneously rotate so as to drive the uniform mixing seats to rotate, the uniform mixing of the magnetic beads can be realized, the outer tray is not required to realize the uniform mixing of the magnetic beads, the experiment time is shortened, the rotation of the outer tray is reduced, so that wear of each component is reduced.

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 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.

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
