Patent ID: 6881190

Claim:
An apparatus for determining a standard pulse-wave-propagation-velocity-related value for a living subject, comprising: a blood-pressure measuring device for measuring a blood pressure of the subject; an age determining device for determining an age of the subject; a standard-pulse-wave-propagation-velocity-related-value determining device for determining the standard pulse-wave-propagation-velocity-related value for the subject, based on the blood pressure of the subject measured by the blood-pressure measuring device and the age of the subject determined by the age determining device, according to a predetermined relationship between (A) (a1) blood pressure and (a2) age and (B) standard pulse-wave-propagation-velocity-related value; and a gender determining device for determining a gender of the subject, wherein the predetermined relationship between (A)(a1) blood pressure and (a2) age and (B) standard pulse-wave-propagation-velocity-related value comprises two predetermined relationships between (A)(a1) blood pressure and (a2) age and (B) standard pulse-wave-propagation-velocity-related value that correspond to male and female, respectively, and wherein the standard-pulse-wave-propagation-velocity-related-value determining device determines the standard pulse-wave-propagation-velocity-related value for the subject, according to one of the two predetermined relationships between (A)(a1) blood pressure and (a2) age and (B) standard pulse-wave-propagation-velocity-related value that corresponds to the gender of the subject determined by the sender determining device.
