A non-intrusive, self-calibrating and self-contained wearable device that measures the concentration of blood constituents or analytes is provided. The device employs low energy, short burst ultrasonic waveforms which are transmitted into the body and a resulting return echo waveform is electronically analyzed to determine a "real-time" blood constituent level. Two return waveform characteristics allow continuous automatic calibration for accurate blood measurements regardless of the patient's condition. The device is a completely self-contained system for the measurement, display and digital recording of blood glucose levels on a moment-to-moment basis.
