ABSTRACT:
The present invention relates to a remote stethoscope system that allows a doctor at one location to listen to the stethoscope sounds coming from a stethoscope being used by a patient in his or her remotely-located home. The acoustic stethoscope sounds are converted into electrical signals, frequency shifted up to the telephone band, and then conveyed over a conventional telephone line. At the doctor's location, the signals are shifted down to their original frequencies and then converted back to audible sound for the doctor's analysis. The sensor used by the patient picks up a wide range of frequencies without any manipulation by the patient.
