Angiopathy diagnosing apparatus
First Claim
1. An apparatus for diagnosing an angiopathy of a living subject, comprising:
- a first pulse-wave-propagation-velocity-related-information obtaining device which obtains a first pulse-wave-propagation-velocity-related information that is related to a first velocity at which a first pulse wave propagates through a first interval of the subject;
a second pulse-wave-propagation-velocity-related-information obtaining device which obtains, at a substantially same time as a time when the first pulse-wave-propagation-velocity-related-information obtaining device obtains the first pulse-wave-propagation-velocity-related information, a second pulse-wave-propagation-velocity-related information that is related to a second velocity at which a second pulse wave propagates through a second interval of the subject that is different from the first interval;
a comparison-value calculating means for calculating a comparison value based on the first pulse-wave-propagation-velocity-related information and the second pulse-wave-propagation-velocity-related information; and
a display device which displays the comparison value calculated by the comparison-value calculating means;
wherein the first pulse-wave-propagation-velocity-related-information obtaining device obtains, as the first pulse-wave-propagation-velocity-related information, the first velocity, and the second pulse-wave-propagation-velocity-related-information obtaining device obtains, as the second pulse-wave-propagation-velocity-related information, the second velocity, and wherein the comparison-value calculating means calculates, as the comparison value, at least one value selected from a difference obtained by subtracting one of the first and second velocities from the other of the first and second velocities, a ratio obtained by dividing one of the first and second velocities by the other of the first and second velocities, and a value obtained by dividing the difference by the ratio.
