A flow channel chip has: a common flow channel; introduction flow channels that are respectively connected to the common flow channel; introduction valves that are respectively disposed in the introduction flow channels; a cleaning liquid flow channel that is connected to the common flow channel; and a cleaning liquid valve that is disposed in the cleaning liquid flow channel. This fluid handling device has: a rotary member for controlling opening/closing of the introduction valves; and a cleaning liquid valve control unit for controlling opening/closing of the cleaning liquid valve. After the rotary member is rotated so as to open/close one of the introduction valves, the cleaning liquid valve control unit causes the cleaning liquid valve to open and causes the cleaning liquid to flow in the common flow channel before the rotary member is rotated so as to open/close another of the introduction valves.

Fluid handling device and fluid handling system

This fluid handling device has a rotary member that is rotatable around the central axis. In the rotary member, a first protruding part for pressing and closing a valve of a flow channel chip and a recessed part for opening the valve without pressing the valve are disposed on the circumference of a first circle around the central axis. The rotary member further has a second protruding part for, when the recessed part is located at the valve in a state where the rotary member is rotated, pressing the valve so as not to open the valve.
