Abstract: A blood pressure monitor including a manually operable pressurizer is disclosed. The blood pressure monitor may include a cuff configured to apply a pressure to a target portion of a body of a user, a pressurizer, a depressurizer, and a sensor to measure a blood pressure. The pressurizer may include a rotator, and be configured to supply a fluid to the cuff, to cause the cuff to apply the pressure, through rotation of the rotator caused by an external rotational force applied to the blood pressure monitor to rotate the rotator. The depressurizer may be configured to reduce the applied pressure applied by the cuff to the target portion.
