Electronic adaption of acoustical stethoscope
First Claim
1. An adapter for a stethoscope comprising an input having a tube connector for audibly connecting with a tube leading to a stethoscope sensor, a battery operated processor for receiving an audio input through said tube connector and converting said audio input to a digital signal, modifying said digital signal to compensate for a predetermined stethoscope distortion that occurs during the transmission of an output signal from said adapter, and an audio output connectable to earpieces of a stethoscope.

Abstract
A stethoscope adapter receives and converts a stethoscope transducer signal using a predetermined inverse function. The adapter then transmits the converted signal as an acoustical signal through a tube connector. With this arrangement, the adapter converts the signal to compensate for undesirable non linear transmission effects through known stethoscopes. The user continues to receive a signal of conventional characteristics and the signal is easily interpreted. Preferably, the adapter interacts with a PDA device to export wirelessly and in real time the signal for additional analysis. The PDA device preferably interacts with the adapter for programming thereof for a particular stethoscope and/or the operation thereof including the on/off function.
