Remote heart sound and lung sound monitoring system design based on ZigBee

This paper proposes a new mold of remote heart sound and lung sound monitoring system in order to solve the problem that at present, heart sound and lung sound cannot simultaneously be collected wirelessly and transmitted remotely. This system applies sound sensor to collect the heart sound and lung sound signal and use ZigBee wireless network to transmit them. FastlCA is used to separate the signal mixtures where exist crosstalk, and Internet network is applied to remotely transmit the signal. Test results show that this system is able to remotely monitor heart sound and lung sound effectively and it has certain practical value for remote health monitoring.
