Problems solved by technology
At present, the stirring process of the solution in the reaction chamber is often done manually, but manual work cannot be repeated, and the work efficiency is relatively low. Therefore, there is an urgent need for a microfluidic chip pipetting drive device that can automatically realize the solution in the reaction chamber. Stirring treatment to improve detection efficiency

The invention discloses a microfluidic chip pipetting driving device, method, and detection equipment. The pipetting driving device includes a mounting bracket, at least one stirring component, a stirring driving mechanism and at least one extrusion driving component, and each of the stirring The components are rotatably arranged on the mounting bracket, the stirring drive mechanism drives each stirring component to rotate relative to the mounting bracket, the stirring component stirs the solution in the reaction chamber on the microfluidic chip, and each extrusion driving mechanism drives the corresponding stirring component to stir The final solution is extruded from the reaction chamber. The invention can automatically stir the solution in the reaction chamber and squeeze the stirred solution out of the reaction chamber, instead of manual operation, thereby improving work efficiency and reducing cost.
Description
technical field [0001] The invention relates to the technical field of microfluidic chips, in particular to a pipetting driving device, method and detection equipment of a microfluidic chip. Background technique [0002] Microfluidics Chip (Microfluidics Chip) uses MEMS technology to shrink a large laboratory system on a glass or plastic substrate, thereby replicating the entire process of complex biology and chemical reactions, and quickly and automatically completes experiments. Channels, reaction chambers, and other functional components for containing fluids are constructed at the level scale, and the movement process of micron-sized fluids in tiny spaces is controlled to build a complete chemical or biological laboratory. A microfluidic chip is a chip that integrates multiple experimental steps. It is generally equipped with small-sized flow channels and chambers arranged in a certain order. Different reagents are released in a certain order and flow into designated cav...
