Superior-and-inferior-limb blood-pressure index measuring apparatus and inferior-limb blood-pressure measuring apparatus
First Claim
1. An apparatus for measuring a superior-and-inferior-limb blood-pressure index of a living subject, comprising:
- a first blood-pressure measuring device which measures a first blood pressure of a right inferior limb of the subject;
a second blood-pressure measuring device which measures a second blood pressure of a left inferior limb of the subject;
a third blood-pressure measuring device which measures a third blood pressure of a superior limb of the subject;
a first information obtaining device which obtains first information relating to a first velocity of propagation of a first pulse wave which propagates through a first route a portion of which runs in the right inferior limb;
a second information obtaining device which obtains second information relating to a second velocity of propagation of a second pulse wave which propagates through a second route a portion of which runs in the left inferior limb;
selecting means for selecting one of the measured first and second blood pressures that corresponds to one of the first and second information that relates to a lower one of the first and second velocities; and
index determining means for determining the superior-and-inferior-limb blood-pressure index, based on the selected one of the first and second blood pressures, and the measured third blood pressure.

6. An apparatus for measuring a superior-and-inferior-limb blood-pressure index of a living subject, comprising:
-
a first blood-pressure measuring device which includes a first inflatable cuff adapted to be wound around an inferior limb of the subject and which measures a first blood pressure of the inferior limb;
a second blood-pressure measuring device which measures a second blood pressure of a superior limb of the subject;
a first pulse-wave sensor which detects a first pulse wave which propagates through a portion of the inferior limb that is located on an upstream side of the first inflatable cuff;
sharpness determining means for determining a degree of sharpness of a heartbeat-synchronous pulse of the first pulse wave detected by the first pulse-wave sensor; and
judging means for judging that when the determined degree of sharpness is not greater than a first reference value and the measured first blood pressure is higher than the measured second blood pressure by a value not smaller than a second reference value, the measurement of the first blood pressure by the first blood pressure measuring device is abnormal. - View Dependent Claims (7, 8)

a second blood-pressure measuring device which measures a second blood pressure of a superior limb of the subject;
a first pulse-wave sensor which detects a first pulse wave which propagates through a portion of the inferior limb that is located on an upstream side of the inflatable cuff;
a second pulse-wave sensor which detects a second pulse wave which propagates through the superior limb; and
a display device which simultaneously displays the measured first and second blood pressures and the detected first and second pulse waves. - View Dependent Claims (10)
