Description

Technical Field

[0001] The utility model relates to the technical field of chemiluminescent immunoassay analyzer equipment, in particular to a chemiluminescent immunoassay analyzer. Background Art

[0002] Chemiluminescent labeling immunoassay, also known as chemiluminescent immunoassay (CLIA), is an immunoassay method that directly labels antigens or antibodies with chemiluminescent agents. The chemiluminescent immunoassay instrument consists of two parts, namely the immunoreaction system and the chemiluminescent analysis system. The chemiluminescent analysis system uses the catalysis of the chemiluminescent substance and the oxidation of the oxidant to form an excited intermediate. When this excited intermediate returns to a stable ground state, it simultaneously emits a photon (hM), and the light quantum yield is measured using a luminescent signal measuring instrument. The immunoreaction system is to directly label the luminescent substance (generating an excited intermediate under the excitation of the reactant) on the antigen (chemiluminescent immunoassay) or antibody (immunochemiluminescent assay), or the enzyme acts on the luminescent substrate.

[0003] The chemiluminescent immunoassay analyzer needs to fully mix the sample and the reagent before analysis, and can only analyze and test them after mixing. However, the existing chemiluminescent immunoassay analyzer does not have the function of mixing the sample and the reagent, and it is not convenient to control the feeding of the sample and the reagent separately, resulting in poor ratio effect, affecting the subsequent analysis data. Therefore, those skilled in the art provide a chemiluminescent immunoassay analyzer to solve the problems raised in the above background technology. Utility Model Content

A pair of sliders are slidably connected in the slide grooves, and the other ends of the sliders are fixedly connected to hinged rods, and the other ends of the hinged rods are hinged to hinged seats, and the hinged seats are fixedly connected to the inner side walls of the chemiluminescence immunoassay analyzer body, and buffer springs are fixedly connected between the hinged rods on the same side.

[0010] As a further solution of the utility model: the incomplete gear is meshed with the driven gear.

In some occasions where repetitive operations are required, the consistency and accuracy of the operation can be guaranteed, and the feeding amount and speed of the reagents or samples can be accurately controlled by controlling the forward and reverse rotation of the servo motor. When the transmission rod rotates, the rotating rod is driven to perform a circular motion, so that the mixing blades, the mixing cover and other components are mixed synchronously, and the samples and reagents can be fully mixed, thereby improving the mixing effect and product quality;

[0012] Because the shock absorbing mechanism is provided, the setting of the shock absorbing plate, the slide groove and the slider can effectively reduce the vibration generated by the servo motor from being transmitted to other functional components of the chemiluminescence immunoassay analyzer body, thereby protecting the stability and accuracy of the instrument. Through the design of the hinged rod and the buffer spring, part of the vibration force can be transferred to the shock absorbing plate, and through the buffering effect of the spring, the influence of the vibration on the instrument body can be further reduced, the service life of the instrument can be extended, the influence of the vibration on the instrument can be reduced, the stability and accuracy of the instrument can be maintained, and the test results of the chemiluminescence immunoassay can be ensured to be accurate and reliable.
