  • Patent number: 11754066
    Abstract: A pump system contains a vibration actuator which can be electromagnetically driven, a sealed chamber connected to a suction port and a discharge port, and a movable wall for changing a volume of the sealed chamber. The movable wall is displaced due to drive of the vibration actuator to supply fluid in the sealed chamber into a cuff. The pump system detects pressure in the cuff based on a consumption current of the vibration actuator.
