Appliance

An appliance having a plurality of functions including a blood pressure measurement function and including a belt that is configured to be worn around a wrist of a user, the appliance comprising:

• a fluid bladder disposed in the belt;
• an acceleration sensor configured to produce an acceleration signal representing an acceleration of the belt;
• a first main body comprising a first display region that is positioned in an area of the belt that corresponds to a volar-side surface or a radius-side surface of the wrist;
• and
• a second main body comprising:
• a second display region that is positioned in an area of the belt that corresponds to a back-side surface of the wrist;
• a pump configured to supply air to the fluid bladder;
• a pump driving circuit configured to drive the pump;
• and
• a pressure sensor configured to detect pressure in the fluid bladder,
• wherein the second main body is larger in size than the first main body,
• wherein the appliance includes a control unit that detects, based on the acceleration signal, whether or not a posture of the wrist is within an acceptable range of a recommended blood pressure measurement posture, and performs a first control, upon detection that the wrist is within an acceptable range of a recommended blood pressure measurement posture, for setting the first display region in a display mode for displaying a blood pressure measurement information only on the first display region and for setting the second display region in a non-display mode, and further performs blood pressure measurement,
• wherein the information that needs to be displayed includes at least blood pressure values obtained through the blood pressure measurement, and
• wherein, when the user wearing the appliance looks into the first display region, a wrist posture of the wrist to which the appliance is attached matches a recommended blood pressure measurement posture and is correct for the blood pressure measurement.
