Abstract
An infusion set () includes: a first flow path () having a first connector () and a downstream connector (); a first open/close valve (), a first liquid surface sensor (), a second liquid surface sensor (), a drip chamber (), and a variable valve () that are provided in this order on the first flow path from the first connector side toward the downstream connector side; a droplet sensor () with which the drip chamber is provided; a second flow path () having a second connector (); and a second open/close valve () provided on the second flow path. The second flow path is in communication with a portion of the first flow path between the first liquid surface sensor and the second liquid surface sensor. The controller is configured to control the first and second open/close valves and the variable valves based on signals from the first and second liquid surface sensors and the droplet sensor.
