Chemiluminescence immunoassay instrument washing system with uniformly-mixing function

Abstract

The invention discloses a chemiluminescence immunoassay instrument washing system with a uniformly-mixing function. The chemiluminescence immunoassay instrument washing system with the uniformly-mixing function comprises a base plate, and a uniformly-mixing base slidably arranged on the base plate, a washing cup holder, a uniformly-mixing assembly, and a washing head, wherein the uniformly-mixingbase has the a clamping position, a material filling position and a washing position in the slide stroke of the uniformly-mixing base; the washing cup holder is fixedly arranged on the uniformly-mixing base, and provided with washing holes distributed in the length direction; the uniformly-mixing assembly is fixedly arranged on the uniformly-mixing base, and used for enabling the washing cup holder to carry out horizontal reciprocating swinging, and carrying out uniformly-mixing on solutions in reaction cups in the washing holes; the washing head is movably arranged on the base plate, and capable of carrying out lifting movement relative to the base plate, and washing needle groups forming one-to-one correspondence with the washing holes and at least one substrate filling needle are arranged on the washing head. A washing mechanism and a uniformly-mixing mechanism are cooperated, and the functions of pre-adsorption and cup puncturing prevention are added, so that the washing effect andthe substrate uniformly-mixing effect are greatly improved, reduction for space occupation and gripper running times is benefited, the detection efficiency is increased, and the running safety and reliability are improved; and meanwhile, realization for the micro development of the instrument is benefited.

Description

technical field [0001] The invention relates to the field of medical testing equipment, in particular to a washing system for a chemiluminescence immunoassay analyzer with a mixing function. Background technique [0002] In the immunoassay experiment, the chemiluminescent immunoassay method is usually used to detect and analyze the body fluid. During the detection process, the experimenter needs to use a special reaction cup to hold the body fluid to be tested. Usually, it will go through filling, mixing, incubation, and washing. and detection steps. In the washing stage, the reagent bottles that have been incubated are mainly rinsed with drugs and filled with substrates. However, the existing washing system takes up a large space and has a single function. During the detection process, the washing is completed. After that, it is necessary to continue to put the cuvette into another mixing mechanism by the gripper for mixing, and the detection efficiency is low. Contents o...
