ACCELERATION PLETHYSMOGRAPHY ANALYSIS APPARATUS AND METHOD USING WAVE FORM FREQUENCY DISTRIBUTION

摘要

The present invention relates to an apparatus and a method for detecting a parameter of an acceleration plethysmorgraphy using a frequency distribution of a waveform type. The apparatus of the present invention comprises: a signal detecting unit for detecting a pulse wave signal of artery blood flow in an arteriola; a signal preprocessing unit for amplifying the pulse wave signal detected by the signal detecting unit, removing a noise, and converting the pulse wave signal into a digital signal; and a calculation processing unit for quadratically differentiating the pulse wave signal received from the signal preprocessing unit, and detecting an acceleration plethysmorgraphy.
