Problems solved by technology

[0004] At present, the cleaning device in the luminescence immunoassay analyzer on the market basically adopts the method of static cuvette, and the magnetic beads are adsorbed on the wall of the static cuvette with a magnet, and then cleaned multiple times with a cleaning needle. Suction in only one direction is easy to gather, resulting in insufficient cleaning and separation, which affects the experimental results

Embodiment

[0028] figure 1 In the shown embodiment, a plurality of cuvette accommodating holes are provided along the circumference of the turntable to form a plurality of cleaning positions, and there are five cuvette positioning mechanisms above the cleaning positions, and the bottom of the turntable under each cuvette positioning mechanism is respectively Correspondingly, there is a shaking drive assembly, which can be shaken and cleaned correspondingly to a cuvette during work. The multiple cleaning positions on the turntable can be divided into pre-cleaning positions and current cleaning positions. The staff can place the cuvettes to be cleaned and shaken in the pre-cleaning positions. The cleaning position where the cuvette to be cleaned is rotated to the top of the shaking drive assembly. Then the bracket driving motor can be operated, so that the moving bracket drives the shaking drive assembly to move upward until the eccentric block can lift the cuvette in the cleaning positio...

Abstract

The invention discloses a reactant shaking device. The reactant shaking device comprises a base, a rotation disk and a shaking driving mechanism. The rotation disk is rotatingly connected to the base. The rotation disk is provided with one or more cleaning positions. A reactor cup positioning mechanism is arranged above the rotation disc. The shaking driving mechanism comprises a movement support, a support driving motor and shaking driving assemblies. The lower end of the base is fixedly connected to a driving installation plate. The movement support is slidingly connected to the driving installation plate and can be driven through the support driving motor to move up and down along the driving installation plate. In each one of the shaking driving assemblies, a shaking driving motor is installed on the movement support, one end of an extension rod is fixedly connected to an output shaft of the shaking driving motor and the other end of the extension rod is fixedly connected to an eccentric block. The shaking driving assemblies are respectively arranged below the cleaning positions of the rotation disc so that the eccentric block can stretch into a receiving hole of the reactor cup along with upward slipping of the movement support and jack up the reactor cup so that the reactor cup presses against the reactor cup positioning mechanism and the eccentric block is driven through the shaking driving motor to drive the reactor cup to carry out eccentric circling motion and thus the reactant is shaken up.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a reactant shaking device for chemiluminescent immune reaction analysis. Background technique [0002] Immunoassay is an important means of clinical diagnosis and treatment, including viruses, hormones, tumor markers and other detection items. Chemiluminescence immunoassay is the latest immunoassay technology developed after radioimmunoassay, fluorescence immunoassay and enzyme immunoassay. Since chemiluminescence immunoassay does not use any light source, it avoids the interference of background light and stray light, reduces noise, and greatly improves Therefore, chemiluminescence analysis has the advantages of high sensitivity, wide detection range, and good stability of markers, and has increasingly become the most important method for in vitro immunoassays. means. [0003] The working method of the fully automatic chemiluminescence immunoassay analyzer designed bas...
