Abstract
A sample extraction chip and a biological reaction device are disclosed according to the present disclosure. The sample extraction chip includes a chip body and a sample extraction module provided on the chip body, the sample extraction module includes a sample-loading lysis unit, a liquid release-control unit, an extraction unit, a liquid switch-control unit, a liquid collection unit and a sample collection unit, which are connected through flow channels in a sequence of extraction. The liquid release-control unit is configured to store and release liquid reagents, and the liquid switch-control unit is configured to switch between communication of the liquid collection unit and the extraction unit and communication of the sample collection unit and the extraction unit. The sample collection unit includes a front collection portion and a rear collection portion which are both in communication with the liquid switch-control unit.
