Abstract
The present invention relates to a pulse depth index extraction device and method using pressure at a constant velocity. A device comprises: a pressure applying unit for applying a pressure at a constant velocity to a confirmed pulse location in a direction perpendicular to the skin; a pressure pulse wave signal measuring unit for measuring a pressure pulse wave signal generated based on the applied pressure; and a measured signal analysis unit for deriving the pulse depth index (PDI) by using the measured pressure pulse wave signal.
