CloudSteth was established in October 2015, dedicated to the research and operation of an intelligent diagnosis system for heart and lung auscultation. Through deep cooperation with hospital, we have accumulated over 100000 effective cardiopulmonary sound data and established a pediatric auscultation database. The System includes electronic stethoscope, artificial intelligence algorithm and cloud big data platform, which can automatically analyze heart and lung sounds through artificial intelligence algorithm for pneumonia, asthma and congenital heart disease for auxiliary diagnosis.
