![]() ![]() In a blood pressure measuring method performed without watching blood, systolic blood pressure,diastolic blood pressure and mean blood pressure are measured based on a change of blood flow in an artery under a cuff which wraps on a blood pressure measuring portion, through a process of reducing the pressure of the cuff at a slow fixed speed after the pressurization of an expected cuff over the systolic blood pressure, or through a process of pressuring the cuff a fixed speed from a pressure less than the diastolic blood pressure to a pressure more than the systolic blood pressure. The present invention relates to an electronic sphygmomanometer, and, more particularly, to an electronic sphygmomanometer arranged to be operated in accordance with the Korotkoff method and the oscillometric method. An electronic sphygmomanometer according to claim 1, wherein said measurement stopping means stops said measurement of said oscillation in cuff pressure when a number of pulses of said oscillation corresponding to said Korotkoff sound which has been first detected is less than a predetermined number of pulses. Measurement stopping means for stopping measurement of said oscillation in cuff pressure in accordance with a detection of said oscillation before a recognition point of one of a systolic blood pressure and a diastolic blood pressure obtained in accordance with said Korotkoff sound.Ģ. Second blood pressure measuring means for measuring blood pressures in accordance with the change in the level of oscillation overlapping the cuff pressure and An electronic sphygmomanometer employing both a Korotkoff method in which blood pressure is measured in accordance with an appearance or disappearance of Korotkoff sound detected by a cuff pressed to a portion of a living body, and an oscillometric method in which blood pressure is measured in accordance with a change in a level of oscillation in a cuff pressure overlapping a pressure of said cuff, said electronic sphygmomanometer comprising:įirst blood pressure measuring means for measuring blood pressures in accordance with the appearance or disappearance of Korotkoff sound
