Abstract

This drug solution delivery apparatus includes a pump main body, a cartridge main body having a plunger operation unit, and a controller for controlling a drive unit. The plunger operation unit has a slide nut and a rib for restricting movement of the slide nut. The drug solution delivery apparatus further includes an attachment detection sensor for detecting contact of the slide nut with the rib. The controller causes the drive unit to drive in reverse, and determines whether the cartridge main body is new or previously used on the basis of a detection signal of the attachment detection sensor.
