<p><P>PROBLEM TO BE SOLVED: To grasp hemodyamics visually based on pressure brain waves detected from a subject. <P>SOLUTION: A cuff strip wrapped around an upper arm of the subject is pressed by air pressure as prescribed, then the pressure brain waves of the subject are detected with a strain sensor 7 when the pressure is reduced, and the frequency components including Korotkoff sounds are analyzed from the detected pressure brain waves, and a spectrogram Sp is generated, showing the frequency on a vertical line and the time on a horizontal line while showing the strength (amplitude) by design and/or color, and the spectrogram Sp is displayed on a display means 3b. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
