Abstract
A device includes a pulse wave detection device that detects pulse waves; a pressure detection device that detects a pressure; a pulse wave processing device; and a display of displaying pulse wave processing data and pressures. It is provided with a pulse wave detectability test device that determines the pulse wave detectability from a pressure; a pulse wave detection state notification device that notifies the operator of the pulse wave detectability status; a pulse wave/pressure storage device that temporarily stores pulse wave and pressure data; and a pulse wave/pressure comparison device that compares pulse wave and pressure data by comparing temporarily stored past data and the current data. These devices enable the operator to easily determine the pressure to be applied when measuring pulse waves, and provide improvements in the efficiency of pulse wave measurement. Further, because it can store optimal pressure values and the pulse wave data at the time of storage, and can compare present data with past data, the device allows the operator to obtain health data.
