Patent ID: 11225639

Abstract:
A cell sorting device is characterized by including: a main flow channel (14) through which a liquid containing a row of cells including a target cell flows, and in which a cell separation area for separating the target cell from the row of cells is provided at a halfway position in a flow direction, the main flow channel being formed in a substrate (12); a selection flow channel (16) into which the target cell is pushed out from the main flow channel, the selection flow channel being formed in the substrate so as to branch from the main flow channel downstream of the cell separation area; a sub flow channel (18) through which a separating liquid flows, the separating liquid being for separating the target cell from the row of cells and pushing out the target cell into the selection flow channel, the sub flow channel being formed in the substrate so as to intersect with the main flow channel in the cell separation area; a pair of liquid flow generating members (22) for generating a liquid flow of the separating liquid in the sub flow channel, the liquid flow generating members being provided at one end and the other end of the sub flow channel; and a drive control member (23) for actuating the pair of liquid flow generating members, wherein the drive control member actuates the pair of liquid flow generating members in conjunction with each other so that the separating liquid forms a liquid flow in a first direction from the one end to the other end of the sub flow channel and a liquid flow in a second direction opposite to the first direction.
