ELECTRONIC SPHYGMOMANOMETER

摘要

PROBLEM TO BE SOLVED: To permit an abnormality of a pulse wave due to a body movement to be accurately and efficiently detected and to permit the measurement condition of a person to be measured to be determined.SOLUTION: An in-pressurization maximum pulse wave differential amplitude detection unit 13 detects a maximum pulse wave differential amplitude by differentiating the output signal of a pressure sensor 4 while pressure in a cuff 1 is increased by a pressurization unit 2, and an in-depressurization pulse wave differential amplitude detection unit 15 detects a pulse wave differential amplitude by differentiating the output signal of the pressure sensor 4 while the pressure in the cuff 1 is decreased by a depressurization unit 3. A body movement detection unit 16 compares the pulse wave differential amplitude with a value obtained by multiplying the maximum pulse wave differential amplitude by a prescribed number and detects the pulse wave differential amplitude as a body movement when the differential amplitude is equal to or higher than the value and decides that there is an abnormality in the condition of the person to be measured during measurement.
