Abstract

The invention discloses a system and a method for detecting mobile phone cardiac sound based on an earphone interface. The detection system comprises a cardiac sound signal acquiring and processing module for acquiring the cardiac sound signal of a user, a Java mobile information device profile (JavaMIDP) protocol supporting mobile phone and a community center server. In the detection method, a cardiac sound signal is acquired through a cardiac sound sensor; the signal is transmitted to the mobile phone through the earphone interface; a dynamic cardiac sound oscillogram is displayed through the mobile phone; at the same time, the user can upload the cardiac sound data of the user to the community center server through the mobile phone; the community center server receives the data transmitted by the mobile phone in real time through a WEB and compares the cardiac sound data with standard cardiac sound data at the same time; and when the user sends a request for viewing a result through the mobile phone, the community center server automatically responds and feeds back a detection result to the mobile phone of the user. The detection system is easy and convenient to operate and high in real-time property and mobility, and the user can perform cardiac sound detection in the home of the user or in other places conveniently.

Description

technical field [0001] The invention relates to the field of medical signal detection and transmission, in particular to a system for collecting heart sound signals through a mobile phone audio interface and performing data interaction with a community server. Background technique [0002] At present, in my country's medical and health reform and development, medical technology for families, communities and grassroots has become the focus, and early diagnosis and prevention of diseases are the focus of technology. Among many diseases, heart disease has become an important disease that threatens human health, and has the characteristics of being preventable and treatable. Therefore, early diagnosis of heart disease is very important. Certain abnormal activities of the heart can produce murmurs or other abnormal heart sounds. Listening to heart sounds or recording phonocardiograms is of certain significance for the diagnosis of heart diseases. Heart sound signal monitoring equ...
