<P>PROBLEM TO BE SOLVED: To provide a technique for improving the measurement accuracy of a pulse wave upon congestion. <P>SOLUTION: A pulse wave signal processing device obtains a first measuring signal that shows an electric impedance in a measurement site where the pulse wave of a living body is measured, a second measuring signal that shows the amount of received light that has irradiated to and then penetrated through or been reflected from the measurement site, and a third measuring signal that shows a physical quantity corresponding to a movement in a mounted part of the living body or the measurement site, detects whether the measurement site is in a congestive state based on the first measuring signal or the third measuring signal, outputs information that shows the pulse wave of the living body by using the first measuring signal and the second measuring signal when it is in the congestive state, and outputs information that shows the pulse wave of the living body by using the first measuring signal and the third measuring signal when it is not in the congestive state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
