Abstract

The embodiment of the invention provides a microfluidic device, a stirring system and a stirring method, relates to the technical field of biology, and is simple in structure, easy to manufacture and capable of preventing cross contamination of liquid in the microfluidic device. The microfluidic device comprises a microfluidic chip, a stirring cavity, a first cover plate and a stirrer. The micro-fluidic chip comprises at least two inflow micro-channels and at least one outflow micro-channel. The stirring cavity comprises a stirring cavity used for containing liquid to be stirred, the stirring cavity is provided with a first opening and a liquid inlet and outlet which are oppositely arranged, and the liquid inlet and outlet is communicated with the at least two inflow micro-channels and the at least one outflow micro-channel. The first cover plate covers the first opening and is connected with the stirring cavity, and a first mounting hole is formed in the first cover plate; the stirrer comprises a blade and a connecting piece, wherein the blade is arranged in the stirring cavity and connected with the first end of the connecting piece, the second end of the connecting piece penetrates through the first mounting hole and is detachably connected with the driving device, and the driving device is used for driving the connecting piece to rotate.

Description

technical field [0001] The present application relates to the field of biotechnology, in particular to a microfluidic device, a stirring system and a stirring method. Background technique [0002] Microfluidic chip, also known as lab-on-a-chip, refers to the integration of basic operating units such as sample preparation, reaction, separation, and detection involved in the fields of biology, chemistry, and medicine into a chip with The whole process of detection and analysis can be automatically completed on the chip of micron-scale microchannel. [0003] At present, in order to achieve efficient and rapid mixing of liquids in the microfluidic chip, so that the chemical reaction between the liquids is sufficient and the subsequent detection is accurate, the microfluidic chip is usually activated by applying an external ultrasonic field or subjecting the liquid to the force of acoustic radiation. The flow state of the liquid in the liquid is changed, so that the liquid mixin...
