摘要： A detection chip, a method for using a dejection chip, and a detection device are provided. The detection chip includes a chip substrate and a first sealing film that are stacked. The chip substrate includes a first surface, and the first sealing film covers the first surface of the chip substrate The chip substrate further includes a fluid channel on the first surface, and the fluid channel includes a plurality of membrane valve portions. The membrane valve portions are configured to allow a portion of fee first sealing film covering the membrane valve portions to approach and separate, so as to close and open the fluid channel correspondingly.

摘要： A detection chip, a method for using a detection chip and a detection apparatus are provided the detection chip includes a chip substrate and the chip substrate includes a fluid channel and a plurality of liquid cells. The fluid channel is arranged on a surface if the chip substrate and includes a main path and a plurality of branch paths. The plurality of branch paths are respectively communicated to the plurality of liquid cells, the plurality of branch paths are all communicated to the main path, and communication points between the plurality of branch paths and the main path are different. The plurality of branch paths are configured to allow liquid in the plurality of branch paths to be capable of merging into the main path in a same direction.
