Abstract

A multi-dimensional artificial intelligence auscultation device includes multiple heart sound sensors configured to place on different heart sound auscultation positions of the body to be monitored for simultaneously capturing heart sound signals corresponding to the different heart sound auscultation positions, and a processing unit is electrically coupled to the heart sound sensors to perform pre-processing such as filtering, signal amplification and digitization on the collected heart sound signals. The pre-processed heart sound signals are analyzed and cross-compared by an external computing device to obtain the correlations between individual heart sound signals of the multiple heart sound signals.

Claims (24)
