Description
Technical Field
The utility model relates to the technical field of full-automatic chemiluminescence immunoassay analysis, in particular to a compound movement type magnetic particle chemiluminescence reagent pack mixing device.
Background
The full-automatic chemiluminescence immunoassay instrument is matched with a magnetic particle chemiluminescence reagent bag for immunodetection. The conventional magnetic particle chemiluminescence reagent kit in the market is shown in fig. 1, two reagent holding grooves and a clamping hole are formed in the reagent kit, a magnetic bead bottle is clamped in the clamping hole, the magnetic bead bottle can rotate in the clamping hole along the axial direction of the magnetic bead bottle, a circle of toothed plate is arranged at the bottom of the outer wall of the magnetic bead bottle along the circumferential direction, and a suspension with magnetic particles is contained in the magnetic bead bottle. When the magnetic bead bottle is stored for a long time, the magnetic particles in the magnetic bead bottle can be settled and aggregated, and the magnetic bead bottle can be used after being fully and uniformly mixed; in addition, after the coating of the magnetic bead bottle is completed, the physicochemical properties such as the particle diameter of the magnetic particles coated with the protein component (or other components) may be changed, and in this case, the aggregation of the magnetic particles may be further increased, and if the magnetic particles cannot be sufficiently dispersed, the subsequent series of detection results may be abnormal.
At present, the general practice is to place the reagent package in the reagent storehouse of immunoassay appearance, and the magnetic bead bottle of reagent package can carry out two-way rotation along its bottle axis direction, drives the rotation of magnetic particle suspension through the rib in the magnetic bead bottle cavity, will deposit the magnetic particle mixing in magnetic bead bottle bottom because of long-term storage. Also, manufacturers adopt a reagent pack without a rubber plug, and after the reagent pack is directly uncapped in a reagent bin of an immunoassay analyzer, a micro screw stirring paddle is directly inserted into the magnetic particle suspension for stirring and mixing uniformly; the method has the advantages that the limitation is large, the sealing performance of the reagent bag without the rubber plug can be reduced, and the reagent volatilizes seriously, so most manufacturers adopt the rubber plug at the bottle mouth of the reagent bottle more, and the magnetic bead bottle is uniformly mixed at the moment or is uniformly mixed in a bidirectional rotation way in the reagent bin of the immunoassay instrument.

Though the mixing efficiency can be improved by sucking and beating the magnetic particle suspension through the liquid transfer device, the situation that the liquid level is difficult to distinguish visually can occur, and even a large number of bubbles can be generated in the bottle, so that the accuracy and precision of the detection of the machine are affected, and the reagent performance is affected. The magnetic bead bottle is characterized in that a clamping seat capable of clamping the magnetic bead bottle is arranged on the clamping seat, permanent magnets are arranged on two sides of the magnetic bead bottle, magnetic particles deposited on the bottom in the magnetic bead bottle are adsorbed on the bottle wall by the permanent magnets, after a few seconds, the magnetic bead bottle is taken out to be manually rotated for mixing, and the magnetic bead bottle is observed to be free from sedimentation and then can be tested on the machine. The manual mixing is time-consuming and labor-consuming in operation, and the rotation stability of the magnetic bead bottle is not easy to ensure; in addition, the permanent magnet position on the cassette is fixed, leads to the magnetic field unable to change, can't provide suitable magnetic field force to different projects to because the permanent magnet is the absorption time of manual control to the absorption of magnetic particle, consequently once appear excessively adsorbing, can lead to the magnetic particle to agglutinate on the magnetic bead bottle wall again.
