Description
technical field [0001] The present application relates to the field of medical equipment, in particular to a multi-channel microfluidic control device. Background technique [0002] A microreactor is a three-dimensional structural element that can be used for chemical reactions and is manufactured from a solid matrix by means of special micromachining techniques. Microreactors typically contain small channel sizes (equivalent diameters less than 500 µm) and channel diversity in which fluids flow and where desired reactions are required to take place. This leads to a very large surface area / volume ratio in microstructured chemical devices, and in the biomedical field, microreactors are mostly used for the full mixing and reaction between different solvents at the nanoscale. [0003] At present, the use of microreactors mostly adopts the method of pressurized piston cylinder, and various raw materials are pressed into the input end of the microreactor. , is discharged from t...
