Whole-process biological detection device

A whole-process biological detection device, comprising at least one reactor, wherein the reactor comprises at least one sample-loading unit, at least one liquid release-control unit, at least one extraction unit, at least one liquid switch-control unit, at least one liquid collection unit, at least one liquid transfer unit, at least one liquid flow-control unit, at least one liquid quantitative dispersion unit, a plurality of reaction cells, and a plurality of flow channels;

• these units are communicated through the plurality of flow channels, wherein, the at least one sample-loading unit and the at least one liquid release-control unit are respectively communicated to the upstream of the at least one extraction unit, and the downstream of the at least one extraction unit is communicated to the at least one liquid switch-control unit, and the downstream of the at least one liquid switch-control unit is communicated to the at least one liquid collection unit and the at least one liquid transfer unit respectively;
• the at least one liquid collection unit and the at least one liquid transfer unit are respectively located on two sides of the at least one extraction unit, the at least one liquid transfer unit is communicated to the at least one downstream liquid quantitative dispersion unit through a first liquid flow-control unit;
• and the at least one liquid quantitative dispersion unit is in communication with the plurality of downstream reaction cells through a plurality of comb-tooth branch pipes in one-to-one correspondence;
• and
• while the at least one reactor rotates around a chip rotation axis, liquid in the reactor is able to flow from an upstream unit to a downstream unit through each flow channel under centrifugal force or surface tension or both of the centrifugal force and the surface tension.
