Claims

[Claim for Utility Model Registration] A driving air pump that pumps out air under pressure, an air storage chamber such as a cuff that stores the air from the pump and uses the stored pressure to compress the arm, and blood pressure measurement. In an automatic blood pressure monitor equipped with an electromagnetic exhaust valve device that gradually discharges air from the storage chamber during operation, the electromagnetic exhaust valve device has an exhaust hole in the central axis direction of a fixed iron core supported by a yoke. one end of the exhaust hole communicates with the air storage chamber, and an orifice diameter is provided at the tip of a fixed iron core through which the other end of the exhaust hole opens, and the tip of the orifice diameter is connected to the fixed iron core. and facing a rubber valve seat of a movable coil frame equipped with an air relief window, and a current control circuit for linearly moving the movable coil frame is connected to the coil of the movable coil frame. This is an automatic blood pressure monitor.
