Abstract:
A blood-pressure monitor apparatus, comprising:a blood-pressure measuring device which includes an inflatable cuff adapted to apply a pressing pressure to a portion of a living subject and which measures a blood pressure of the subject by changing the pressure of the cuff applied to said portion of the subject;a blood-pressure-relating-information obtaining device which iteratively obtains, from the living subject, blood-pressure-relating information which changes with change of the blood pressure of the subject;a blood-pressure-measurement starting means for starting a blood-pressure measurement of the blood-pressure measuring device, when a subsequent piece of blood-pressure-relating information obtained by the blood-pressure-relating-information obtaining device after the blood-pressure measuring device has measured a last blood pressure of the living subject in a last blood pressure measurement thereof has deviated by not less than a predetermined amount from an initial piece of blood-pressure-relating information obtained by the obtaining device when the blood-pressure measuring device measured the last blood pressure of the subject;a display device which displays a graph representing the pieces of blood-pressure-relating information obtained by the blood-pressure-relating-information obtaining device; anda control device which comprises a determining means for determining a proportion of an amount of change, from said initial piece of blood-pressure-relating information, of each one of subsequent pieces of blood-pressure-relating information iteratively obtained by the obtaining device after the blood-pressure measuring device has measured the last blood pressure of the subject; and a control means for controlling the display device to display the graph representing the initial piece of blood-pressure-relating information and the determined proportion of the amount of change of said each one of subsequent pieces of blood-pressure-relating information, so that the initial piece of blood-pressure-relating information and the determined proportion of the amount of change of said each one subsequent piece of blood-pressure-relating information can be compared with each other on the display device.
