Abstract

The embodiments of the present application provide a microfluidic device, a stirring system and a stirring method, which relate to the field of biotechnology, have a simple structure, are easy to manufacture, and can prevent cross-contamination of liquids in the microfluidic device. The above-mentioned microfluidic device includes a microfluidic chip, a stirring cavity, a first cover plate and a stirrer. The microfluidic chip includes at least two inflow microchannels and at least one outflow microchannel. The stirring cavity includes a stirring cavity for accommodating the liquid to be stirred, and the stirring cavity has a first opening and a liquid inlet and outlet that are oppositely arranged, and the liquid inlet and outlet are communicated with at least two inflow microchannels and at least one outflow microchannel. The first cover plate covers the first opening and is connected with the stirring cavity, and the first cover plate is provided with a first installation hole. The agitator includes a blade and a connecting piece. The blade is arranged in the stirring cavity and is connected with the first end of the connecting piece. The second end of the connecting piece passes through the first installation hole and is detachably connected with the driving device. The driving device is used for driving connection. Pieces rotate.

Description

technical field [0001] The present application relates to the field of biotechnology, and 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 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 made by applying an external ultrasonic field or subjecting the liquid to the effect of sound wave radiation force. The flow state of the liquid in the liquid is changed, thereby realizing the liq...
