<p><P>PROBLEM TO BE SOLVED: To provide a blood-pressure measurement method which detects biosignals by installing a biosignal-detecting means under a body of a subject in a recumbent position, calculates intensity of heartbeat signals by extracting the heartbeat signals from the detected biosignals, and estimates the blood pressure of the subject from the resulting heartbeat intensity signals. <P>SOLUTION: A blood-pressure measurement device comprises: the biosignal-detecting means having a biosignal-detecting part under the body of the subject in the recumbent position; a heartbeat signal-extracting means which extracts the heartbeat signals from the biosignals detected by the biosignal-detecting means; a heartbeat intensity-calculating means which calculates the intensity of the heartbeat signals; a blood-pressure-calculating means which estimates the blood-pressure of the subject from the heartbeat intensity signals. The blood-pressure-calculating means is a blood-pressure measurement device which calculates the blood-pressure from a variation of the blood-pressure based on the value of the heartbeat intensity obtained by the heartbeat intensity-calculating means and from a standard value of blood-pressure which is previously calculated. Additionally, in the blood-pressure measurement device, change of the intensity is reduced by the lying position in which the biosignal-detecting means is installed mainly under the buttocks of the subject. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
