<p><P>PROBLEM TO BE SOLVED: To provide a blood pressure measuring device capable of measuring a blood pressure highly precisely while stabilizing a pulse wave even though distances between a site to be measured of a subject, and a light emitting element and a light receiving element are changed due to the movement of the subject or the disturbance such as pulsation in a blood pressure measurement using the measurement of the pulse wave by light. <P>SOLUTION: This blood pressure measuring device has the light receiving element receiving the light reflected by the face of the light emitting element side of the expandable member of a cuff of the light irradiated toward the expandable member from the cuff of the light emitting element, the output signal of the receiving element is processed as a noise component along with a pulse wave signal having measured the subject, thereby the noise component due to the movement of the subject and the disturbance such as the pulsation can be reduced, the blood pressure measuring device capable of always measuring the blood pressure highly precisely while stabilizing the pulse wave of the subject even though the device can not be completely secured the subject can be provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
