Electronic Hemomanometer, Method of Correcting Pulse Wave Data of Electronic Hemomanometer, Program for Causing a Computer to Execute Procedures and Computer-Readable Recording Medium

An electronic hemomanometer comprising:

• a time differentiating means for time-differentiates signals each formed by superposing a pulse wave amplitude component on a cuff pressure to time-differentiated signals;
• an envelope computing means for computing an envelope consisting of the time-differentiated signals;
• a maximal envelope value detecting means for detecting a maximal value in a computed envelope;
• an ascending sort means for sorting the time-differentiated signals generated prior to a maximal envelope value in ascending order;
• a descending sort means for sorting the time-differentiated signals generated after the maximal envelope value in descending order;
• and
• an envelope forming means for forming the envelope consisting of the time-differentiated signals sorted by the ascending and descending sort means.
