Abstract

The present invention is an apparatus for simultaneously transmitting biomedical signals and human voice over a telephone. The invention is also a telephone line adapted to receive communication from the receiving unit at a second end of the line while simultaneously transmitting biomedical signals and human voice from the first end. The apparatus comprises a sensor, a cable, and a transmitter device. The sensor comprises electrodes attached to a pad with a wire connected to each electrode. The cable groups the wires into a single unit and leads them to the transmitter device. The transmitter device comprises a converter and a acoustic. In operation, the sensor takes biomedical signals in the form of electronic data. The data is conveyed via the wires where it reaches the converter. The converter converts the biomedical electronic data into acoustic signal which is emitted by the acoustic in circuit with the converter. The acoustic signals are translatable back to biomedical signals by the receiving unit. The acoustic is disposed within acoustic range of the microphone of a telephone. The acoustic is disposed in such a manner as to allow oral speech from the patient to be transmitted simultaneously with the transmission of the sound. The invention may also comprise its own telephone member which may then be plugged into an conventional telephone base.
