Abstract
An aspirator for an endoscopic system has a suction nozzle for aspirating obstacles and disposed at an end of an endoscope, a suction pump, a suction flask for receiving the aspirated obstacles, and a suction conduit for connecting the suction nozzle to the suction pump via the suction flask. The aspirator further comprises an electromagnetic valve disposed in the suction conduit, and an electromagnetic valve controller. The electromagnetic controller controls the electromagnetic valve such that the suction conduit is closed when an aspiration command signal is not supplied from an aspirator button during the operation of the suction pump, and such that the suction conduit is alternately opened and closed when the aspiration command signal is supplied from the aspirator button during the operation of the suction pump.
