The invention is an improved aspirator for use in medical procedures. The aspirator is provided with a rubber band powered piston control valve that maintains the valve in the off position. When operated to the on position by a user, the rubber band is placed in tension mode so that when released by the user the rubber band returns the valve to the off position. The rubber band powered piston valve aspirator is simple to disassemble without tools for cleaning and sterilization.
