Auxiliary operation device for ELISA experiment

Abstract

The invention relates to an auxiliary operation device for an ELISA (enzyme-linked immunosorbent assay) experiment. The auxiliary operation device comprises a support leg assembly, a telescopic rod, a wrist support part and a universal rotation device, wherein the bottom of the support leg assembly is connected with universal traveling wheels, the telescopic rod is mounted on the support leg assembly, the wrist support part is connected with the telescopic rod through the universal rotation device which comprises a rotation piece and a roller, the rotation piece comprises a rod sleeve and a connecting rod fixed with the rod sleeve arranged on the periphery of the telescopic rod in a sleeving manner, the roller is mounted between the rod sleeve and the telescopic rod, and the wrist support part is mounted at the top end of the connecting rod. The auxiliary operation device meets ergonomic requirements and can improve sample adding stability obviously for an operator, so that the sample adding accuracy is improved, the probability that a sample and a reagent splash out of a micro-hole during sample adding is reduced effectively, and occurrence of false positive and false negative conditions and medical pollution is reduced. An arm of the operator is supported during operation, so that the working intensity of the operator is reduced effectively.

Description

technical field [0001] The invention relates to an auxiliary operating device for an enzyme-linked immunoassay experiment arm. Background technique [0002] In the ELISA experiment, a large number of samples need to be accurately added to the microwells of the ELISA plate. The size of each ELISA plate is the same, and there are 96 (12×8) microwells, the operator needs to accurately add 96 subjects’ samples or various reagents into the corresponding microwells, and add The sampling process needs to be careful, and the specimen or various reagents cannot be splashed to avoid contamination of the adjacent microwells. When adding samples to the microwells, the existing operation process is: the left hand holds the specimen or reagent, the right hand holds the pipette, the pipette absorbs the specimen or reagent and then adds it to the microwell of the microplate, and the right hand needs to constantly go back and forth Aspirating and adding samples; operators repeat the same o...

Problems solved by technology

When adding samples to the microwells, the existing operation process is: the left hand holds the specimen or reagent, the right hand holds the pipette, the pipette absorbs the specimen or reagent and then adds it to the microwell of the microplate, and the right hand needs to constantly go back and forth Aspirating and adding samples; operators repeat the same operation of adding samples thousands or even tens of thousands of times every day, and their eyes and arms are sore and tired. It is inevitable that there will be errors in adding samples, and the operation efficiency is low.

There is currently no related auxiliary equipment or device that can be used for this operation
