Blood-pressure monitoring apparatus
First Claim
1. A blood-pressure monitoring apparatus comprising:
- a measuring device which includes an inflatable cuff adapted to apply a pressing pressure to a first body portion of a living subject and which measures a blood-pressure value of the living subject by changing the pressing pressure of the inflatable cuff;
a blood-pressure-relating-information obtaining device which iteratively obtains a piece of blood-pressure-relating information which changes in relation to a change of the blood pressure of the living subject;
starting means for starting, when the obtained blood-pressure-relating information satisfies a predetermined condition with respect to at least one reference value, a blood-pressure measurement of the measuring device; and
a display device which displays a first graphical representation of the obtained blood-pressure-relating information, and a second graphical representation of the reference value, so that the first graphical representation is comparable with the second graphical representation.

a pulse-wave-propagation-relating-information obtaining device which iteratively obtains a piece of pulse-wave-propagation-relating information relating to propagation of a pulse wave through an arterial vessel of the living subject;
relationship determining means for determining a relationship between pulse-wave-propagation-relating information and blood pressure, based on at least one blood-pressure value of the living subject measured by the measuring device and at least one piece of pulse-wave-propagation-relating information obtained by the pulse-wave-propagation-relating-information obtaining device; and
estimating means for estimating a blood-pressure value of the living subject, based on each piece of pulse-wave-propagation-relating information of a plurality of pieces of pulse-wave-propagation-relating information obtained by the pulse-wave-propagation-relating-information obtaining device, according to the determined relationship between pulse-wave-propagation-relating information and blood pressure.

17. An apparatus according to claim 16, wherein the blood-pressure-relating-information obtaining device further comprises average calculating means for calculating, as the obtained blood-pressure-relating information, an average of a plurality of blood-pressure values estimated by the estimating means.
-
18. An apparatus according to claim 16, wherein the blood-pressure-relating-information obtaining device further comprises change-value calculating means for calculating, as the obtained blood-pressure-relating information, a value relating to a change of a first blood-pressure value estimated by the estimating means from a second blood-pressure value estimated prior to the first estimated blood-pressure value by the estimating means.
