Auscultation Diagnostic Support Device

This invention is a screening tool for heart and lung aliments. Advanced signal processing techniques have been applied to heart and lungs sounds as an aid to diagnoses. A database containing patient demographics, relevant health information, physical exam results, ECG traces, echocardiograph diagnoses, and auscultatory findings obtained with a traditional stethoscope are all linked together with digitized recordings of patient data. Included are recordings from five (5) standard auscultatory areas. The initial prototype device provides two acoustic channels and one ECG channel which can be stored, digitized and processed on a laptop computer; noise cancellation using adaptive filtration techniques are developed enabling use in noisy environments. The laptop computer is also used to create multiple time/frequency analyses and display screens.
