摘要： A method of monitoring for changes in a health condition using a non-invasive blood pressure measuring device includes obtaining an acoustic signal from a blood vessel using an audio transducer, converting the acoustic signal to a blood pressure measurement, sampling the pressure measurement over a sample frequency, determining average pressure from the sampled pressure measurement over a target time period, monitoring the average pressure for deviation from a threshold pressure range, and generating an alert signal from the blood pressure measuring device if a deviation from the threshold pressure range is detected.

摘要： Embodiments provide a blood pressure measuring device that: (a) transmits, with an acoustic transducer, acoustic energy at a first frequency towards a blood vessel; (b) first measures an electrical property of the acoustic transducer; (c) transmits, with the acoustic transducer, acoustic energy at a second frequency towards the blood vessel; (d) second measures the electrical property of the acoustic transducer; (e) determines a change in the electrical property of the acoustic transducer between the first measuring and the second measuring, the determined change corresponding to a change in reflected acoustic energy from the blood vessel; (f) determines a resonant frequency of vibration of a wall of the blood vessel as a function of the determined change in the electrical property of the acoustic transducer; and (g) generates a blood pressure measurement as a function of the determined resonant frequency of vibration of the wall of the blood vessel.
