<p>A chemical infusing device capable of automatically preventing bubbles from being discharged at a chemical syringe to which chemical suction is not completed or chemical from being infused at a chemical syringe from which bubble discharge is not completed without the need of additionally providing a release switch. In this device, an initial state provides an operation permitting only chemical suction in which the piston member of the chemical syringe is retracted by a syringe drive mechanism (117) in real-time response to an manual operation, then, when a suction completion is detected at its moved distance/position, an operation permitting only bubble discharge is provided in which the piston member is advanced by a syringe drive mechanism (117) in real-time response to an manual operation, and, when a discharge completion is detected at its moved distance/position, an operation permitting chemical infusion is provided in which the piston member is advanced by a syringe drive mechanism (117) in association with set data or the like.</p> |
