Background technique

In the biomedical industry, there are various reagents for in vitro diagnosis, including reagents for protein detection, reagents for sugar detection, reagents for enzyme detection, and other physiological, biochemical or immune function indicators. These diagnostic reagents are generally prepared by mixing several biochemical reagents. In the mixing process of some specific biochemical reagents, there are strict requirements on the order of mixing. For example, a part of the reagents must be mixed first to form a mixed solution, and then the mixed solution is added to another reagent in batches. Otherwise, some side reactions will occur and the diagnostic reagents will fail. However, the general stirring device cannot meet this demand. It is necessary to manually discharge the mixed solution, then pour other reagents into the stirring device, and then gradually add the mixed solution to the stirring device to stir and mix, which will easily lead to reagent leakage. Workers waste time and effort.
