Abstract

An arteriostenosis inspecting apparatus including a left-superior-limb-blood-pressure measuring device which measures a left-superior-limb blood pressure of a left superior limb of a living subject, a right-superior-limb-blood-pressure measuring device which measures a right-superior-limb blood pressure of a right superior limb of the subject, and a left-and-right-superior-limb-blood-pressure-ratio determining device which determines a left-and-right-superior-limb blood-pressure ratio as a ratio of one of the left-superior-limb blood pressure and the right-superior-limb blood pressure to the other.

Claims

1. An arteriostenosis inspecting apparatus, comprising:

a left-superior-limb-blood-pressure measuring device which measures a left-superior-limb blood pressure of a left superior limb of a living subject;

a right-superior-limb-blood-pressure measuring device which measures a right-superior-limb blood pressure of a right superior limb of the subject; and

a left-and-right-superior-limb-blood-pressure-ratio determining means for determining a left-and-right-superior-limb blood-pressure ratio as a ratio between the left-superior-limb blood pressure measured by the left-superior-limb-blood-pressure measuring device and the right-superior-limb blood pressure measured by the right-superior-limb-blood-pressure measuring device.

2. An arteriostenosis inspecting apparatus according to claim 1, wherein the left-and-right-superior-limb-blood-pressure-ratio determining means determines the left-and-right-superior-limb blood-pressure ratio by using a lower one of the left-superior-limb blood pressure and the right-superior-limb blood pressure as a numerator of said ratio and using a higher one of the left-superior-limb blood pressure and the right-superior-limb blood pressure as a denominator of said ratio.

3. An arteriostenosis inspecting apparatus according to claim 1, wherein the left-and-right-superior-limb-blood-pressure-ratio determining means determines the left-and-right-superior-limb blood-pressure ratio by using a pre-selected one of the left-superior-limb blood pressure and the right-superior-limb blood pressure as a denominator of said ratio.

4. An arteriostenosis inspecting apparatus according to claim 1, further comprising a display device which displays the left-and-right-superior-limb blood-pressure ratio determined by the left-and-right-superior-limb-blood-pressure-ratio determining means.

5. An arteriosclerosis evaluating apparatus according to claim 4, wherein the display device further displays the left-superior-limb blood pressure measured by the left-superior-limb-blood-pressure measuring device, and the right-superior-limb blood pressure measured by the right-superior-limb-blood-pressure measuring device.

6. An arteriostenosis inspecting apparatus, comprising:

a left-superior-limb-blood-pressure measuring device which measures a left-superior-limb blood pressure of a left superior limb of a living subject;

a right-superior-limb-blood-pressure measuring device which measures a right-superior-limb blood pressure of a right superior limb of the subject; and

a left-and-right-superior-limb-blood-pressure-ratio determining device which determines a left-and-right-superior-limb blood-pressure ratio as a ratio between the left-superior-limb blood pressure measured by the left-superior-limb-blood-pressure measuring device and the right-superior-limb blood pressure measured by the right-superior-limb-blood-pressure measuring device.
