Beschreibung
Zusammenfassung:	A blood-pressure gauge includes: an opening valve connected to a sensing cuff and being in an open state with being conducted to outside air or a closed state with not being conducted to the outside air; a pressure cuff controller controlling the pressure cuff to a compression state with fluid supply to the pressure cuff and a measurement site being compressed via the pressure cuff or a release state with the fluid discharging from the pressure cuff and compression releasing via the pressure cuff; an opening valve controller controlling the opening valve to the open state or the closed state; and a blood pressure calculator calculating a blood pressure from a pressure change of the sensing cuff at the closed state of the opening valve. The sensing cuff has restorability to make a volume in the sensing cuff a predetermined volume when the opening valve is in the open state.
