Abstract
A subject evaluation value measuring apparatus, functioning as a cuff volumetric pulse wave obtaining apparatus, includes a pulse wave determining device (i.e., a cuff volumetric pulse wave determining device)that determines, using an inverse transfer function 1H(f), stored in a ROM (i.e., an inverse transfer function memory), that corresponds to a pre-determined transfer function H(f) between input, i.e., pressure pulsation produced in a cuff, and output, i.e., pressure pulsation detected by a pressure sensor, a no-delay cuff volumetric pulse wave P(t) having substantially no delay of transmission, based on an actual cuff pulse wave signal SM outputted by the pressure sensor. The thus determined cuff volumetric pulse wave P(t) is free of waveform distortion and accordingly enjoys high accuracy.
