  • Electronic hemomanometer, method of correcting pulse wave data of electronic hemomanometer, program for causing a computer to execute procedures and computer-readable recording medium
    Patent number: 8652055
    Abstract: A pulse wave data correcting method in an electronic hemomanometer which is designed to time-differentiate signals each formed by superposing a pulse wave amplitude component on a cuff pressure, to compute an envelope consisting of the time-differentiated signals, to detect the maximal value in the computed envelope, to sort the time-differentiated signals generated prior to the maximal envelope value in ascending order, to sort the time-differentiated signals generated after the maximal envelope value in descending order, and to form an envelope consisting of the sorted time-differentiated signals.
