1. An apparatus for simultaneously transmitting biomedical readings from a patient and for bidirectionally communicating voice signals over a telephone, the telephone having a telephone microphone and a telephone speaker, the apparatus comprising:

  • a sensor to sense the biomedical readings; and

    a transmitter device comprising a converter to convert the biomedical readings into electrical drive signals and an acoustic circuit to convert the electrical drive signals into acoustic signals, the acoustic signals being translatable back to signals representative of the biomedical readings by a remote receiving unit, the transmitter device being disposed within acoustic range of the telephone microphone such that the acoustic circuit transmits the acoustic signals to the telephone microphone, the transmitter device being disposed such that the telephone microphone is also simultaneously available to receive oral communication from the patient simultaneously with the acoustic signals converted from the biomedical readings, the telephone speaker being disposed to be available to produce audible voice signals to the patient while the acoustic signals converted from the biomedical readings are being transmitted.
