Micro-fluidic chip and influenza A virus detection kit

The invention belongs to the field of in-vitro diagnosis, and particularly relates to a micro-fluidic chip and an influenza A nucleic acid detection kit. The chip sequentially comprises a cover plate, a first clamping plate, a second clamping plate and a bottom plate from top to bottom, a first sample loading cavity is formed in the cover plate; a second sample loading cavity, a first buffer cavity and a test paper cavity which are sequentially connected through a runner are formed in the first clamping plate; the second clamping plate is provided with a reaction cavity, a second buffer cavity and a water absorption cavity which are sequentially connected through a flow channel. An integrated small detection device is ingeniously arranged. The structure is located in different chip layers, and it is guaranteed that all operation units work independently. The aligned buffer cavities are arranged between the two interlayers, products are fully and uniformly diluted through the design of the buffer cavities, the
