Abstract

The invention discloses a volume pulse wave signal processing method, a blood pressure measuring device and a storage medium. The volume pulse wave signal processing method comprises the steps of extracting single-cycle waveform morphological characteristics from volume pulse wave signals, acquiring space-time linked characteristics from the single-cycle waveform morphological characteristics by using a two-way recirculating network, inputting the space-time linked characteristics to a shared deep convolutional network so as to acquire a characteristic graph, and inputting the characteristic graph to a fully-connected network, so as to acquire a blood pressure fitted value. Through processing the volume pulse wave signals by using the two-way recirculating network, the shared deep convolutional network and the fully-connected network, high-dimension information can be extracted from the volume pulse wave signals, so that more available information is provided for application of a pulsewave analysis method, and the accuracy of the pulse wave analysis method is improved. The invention is extensively applied to the technical field of signal processing.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a volume pulse wave signal processing method, a blood pressure measuring device and a storage medium. Background technique [0002] Blood pressure is an important physiological index, which can be measured by methods such as arterial tension method, volume compensation method, pulse wave conduction method and pulse wave analysis method. Among them, the pulse wave analysis method is to process the measured pulse wave signal to obtain the blood pressure value, the pulse wave conduction method needs to collect multiple volume pulse signals for processing, and the pulse wave analysis method only needs to collect a single volume pulse signal for processing , so the pulse wave analysis method has more advantages than the pulse wave conduction method. However, the existing pulse wave analysis technology mainly has shortcomings such as not fully exploiting the high-dimensional...
