  • Wearable auscultation system and method
    Patent number: 7976480
    Abstract: A method and system for monitoring physiological parameters is useful for remote auscultation of the heart and lungs. The system includes an acoustic sensor (105) that has a stethoscopic cup (305). A membrane (325) is positioned adjacent to a first end of the stethoscopic cup (305), and an impedance matching element (335) is positioned adjacent to the membrane (325). The element (335) provides for acoustic impedance matching with a body such as a human torso. A microphone (315) is positioned near the other end of the stethoscopic cup (305) so as to detect sounds from the body. A signal-conditioning module (110) is then operatively connected to the acoustic sensor (105), and a wireless transceiver (115) is operatively connected to the signal-conditioning module (110). Auscultation can then occur at a remote facility that receives signals sent from the transceiver (115).
