Multi-flux micro-fluidic chip based on active fluid flow control

A multi-flux micro-fluidic chip based on active fluid flow control, including a chip body, wherein the chip body includes a fluid inflow cavity, reaction-quantification cavities and waste liquid cavities, and the fluid inflow cavity is communicated with an external air path;

• characterized in that the multi-flux micro-fluidic chip based on active fluid flow control further includes a fluid path distribution cavity disposed at a middle position of the chip body;
• the number of the reaction-quantification cavities is four or more, and the four or more reaction-quantification cavities are distributed on two sides of the fluid path distribution cavity in rows to form a first row of reaction-quantification cavities and a second row of reaction-quantification cavities respectively;
• and the reaction-quantification cavities are communicated with a fluid outlet of the fluid path distribution cavity through respective fluid path branches, and a fluid inlet of the fluid path distribution cavity is communicated with a fluid outlet of the fluid inflow cavity and an external fluid path;
• the waste liquid cavities include a first waste liquid cavity, a second waste liquid cavity and a third waste liquid cavity and three said waste liquid cavities are separately disposed on a periphery of the chip body in a semi-enclosed mode, wherein the first waste liquid cavity and the second waste liquid cavity are located on two sides of the chip body, the third waste liquid cavity is communicated with the first waste liquid cavity and the second waste liquid cavity, the first waste liquid cavity is communicated with the first row of the reaction-quantification cavities, and the second waste fluid cavity is communicated with the second row of reaction-quantification cavities;
• the third waste liquid cavity includes a waste liquid pool b, a middle cover plate b covering an open end of the waste liquid pool b and an upper cover plate b covering the middle cover plate b, wherein the middle cover plate b has a surface facing the upper cover plate b and provided with an absorbent paper assembling groove b, air outlets a are formed in a bottom of the absorbent paper assembling groove b, and air outlets b are formed in a surface, opposite to an opening of the absorbent paper assembling groove b, of the upper cover plate b in a penetration mode.
