Abstract

The invention discloses a method for extracting blood pressure data from a pulse wave signal and a device thereof. The method comprises: model training and blood pressure data extraction; wherein themodel training comprises: acquiring the pulse wave and corresponding blood pressure data, and performing preprocessing; performing complete waveform detection and separation of the pre-processed pulsewave; performing frequency domain transformation on each complete pulse wave waveform, and extracting the frequency domain features; taking the frequency domain feature as an input, taking the corresponding blood pressure value as an output, combining with the neural network for predictive model training, and obtaining a blood pressure data prediction model. The blood pressure data extraction includes the following steps: inputting the frequency domain feature to-be-predicted into a blood pressure data prediction model, and outputting a blood pressure value. The pulse wave is detected and separated, the frequency domain is transformed to extract features, which can effectively avoid the problem of difficult feature detection in a time domain feature extraction method, provides more accurate samples for subsequent model training with neural network, and improves the prediction accuracy of blood pressure measurement and reduces the prediction error.
