PROCESS FOR ULTRASONIC PRESSURE MEASUREMENT IN A LIQUID USING MICRO-BUBBLES

In an ultrasonic process for pressure measurement in a liquid containing stabilized micro-bubbles in a system, ultrasonic pulses are irradiated into the liquid and made to interact with micro-bubbles. The amplitude and/or frequency changes of the ultrasonic signals diffused are recorded and assessed...

Summary:In an ultrasonic process for pressure measurement in a liquid containing stabilized micro-bubbles in a system, ultrasonic pulses are irradiated into the liquid and made to interact with micro-bubbles. The amplitude and/or frequency changes of the ultrasonic signals diffused are recorded and assessed in relation to the ultrasonic pulses irradiated and/or previously received. A descriptio is given of means to mesure the blood pressure which can be used with the pressure-measurement process. Dans un procédé manométrique par ultrasons dans un liquide contenant des microbulles stabilisées dans un ensemble, des impulsions ultrasonores sont irradiées dans le liquide et amenées à une interaction avec les microbulles. Les variations d'amplitude et/ou de fréquence des signaux diffusés ultrasonores sont enregistrées et évaluées par rapport aux impulsions ultrasonores irradiées et/ou précédemment reçues. Sont décrits des moyens pour mesurer la pression sanguine, qui peuvent s'utiliser avec le procédé manométrique.
