International ClassesA61B 005/00A61B 008/06 AbstractA medical diagnostic method comprises the steps of automatically sensing an acoustic vibration inside a person, converting the sensed acoustic vibration to an electrical signal, amplifying the electrical signal, and converting the amplified electrical signal to an acoustic pressure wave. The steps of sensing and converting the sensed acoustic vibration to an electrical signal are implemented by operating an acoustoelectric transducer in a hand held device, and the method further comprises the step of holding the hand held device against a skin surface of the person. The method further comprises the steps of wirelessly transmitting the amplified signal to a receiver and printing or displaying the transmitted acoustic information after a processing thereof. The acoustic information or the processed information derived therefrom is advantageously printed in graphic form. Original acoustic information or processed information may be stored for subsequent use in diagnosing a patient. In another embodiment, the device is further provided with an ultrasonic generator, sensor, and processing circuitry for providing an indication of moving fluid, such as blood. | |
