Sample liquid adding and uniform mixing device

Abstract

The invention discloses a sample liquid adding and uniform mixing device which comprises a first box body, a liquid adding assembly, a second box body and a conveying assembly, side plates are installed on the two sides of the second box body, the first box body is installed on the side plates, reagent bottles are arranged in the first box body, the liquid adding assembly is installed in the first box body, and the conveying assembly is installed on the second box body. A conveying assembly is arranged in the second box body, a uniform mixing assembly is arranged on the upper surface of the second box body in a sliding fit mode, and the conveying assembly is connected with the uniform mixing assembly and can be used for helping to achieve adding of batch sample normal saline or pretreatment reagents, automatic uniform mixing can be achieved after adding, the experiment process is optimized, and experiment operators are reduced; the problem that the liquid adding amount is not accurate due to manual operation is avoided, pollution can be reduced, the reagent bottle can meet the requirements of different experiments, the working efficiency is improved, and the experiment time is shortened.

Description

technical field [0001] The invention relates to the technical field of medical laboratory equipment, in particular to a sample liquid adding and mixing device. Background technique [0002] Sample addition and mixing are experimental steps often involved in the field of PCR molecules. Before adding physiological saline or pretreatment reagents to the sample tube, the sample tube cap should be opened first, then the required liquid should be added, and finally the sample tube cap should be closed for shaking and mixing. At present, the spotting instrument is used to absorb and transfer the DNA template through the setting of no plate position, but it cannot be used for adding liquid and mixing before sample processing. [0003] At present, the PCR sample sampling tubes received by the laboratory are not filled with normal saline or pretreatment reagents. Usually, the operator needs to manually add normal saline or pretreatment reagents through a pipette. After adding normal ...
