Automatic liquid adding device for enzyme-linked immunosorbent assay (ELISA) test

Abstract

The invention relates to an automatic liquid adding device for ELISA (enzyme-linked immunosorbent assay) test, which comprises a bearing base, the top of the bearing base is rotatably connected with the lower end of a rotary bracket, and a first base for placing an elisa plate, a second base for placing a recovery frame, a third base for placing a gun head box and a fourth base for placing a liquid tank are uniformly arranged at the top of the bearing base along the circumferential direction; the pressing and clamping assemblies are used for clamping the pipette, and the pressing and clamping assemblies are arranged at the ends of the transverse supports on the top of the rotating support correspondingly; the test tube placing assembly is arranged on the fourth base, is positioned on one side of the liquid placing groove and is used for placing a test tube filled with an adding reagent; the dumping assembly is arranged on the fourth base, is positioned between the liquid accommodating groove and the test tube accommodating assembly, and is used for pushing the test tube and guiding the reagent in the test tube into the liquid accommodating groove; the horizontal rotating assembly is arranged on the third base and is used for placing a gun head box; automatic liquid taking, enzyme liquid adding and gun head replacing are achieved, meanwhile, the effectiveness and accuracy of experimental analysis are guaranteed, the workload is relieved, and the test efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to an automatic liquid adding device for ELISA test. Background technique [0002] Enzyme-linked immunosorbent assay (ELISA) enzyme-linked immunosorbent assay (ELISA) is the localization of various intracellular components by immunoenzyme staining, and studies the synthesis of anti-enzyme antibodies. It is a small amount of immunoprecipitation reaction; it can quantitatively detect antigen or antibody components in body fluids. [0003] The operation of the liquid addition process in the existing ELISA test process is manual operation, and automatic liquid addition cannot be realized. In addition, during the test process, it is necessary to frequently weigh the extraction reagent and add it to the reactant, and use a pipette gun to take the amount multiple times. After the action of taking liquid and pipetting is completed, the tester needs to replace the head when the act...
