Abstract:
To discuss the ultrasonic testing intelligent infusion pump tubing bubble method. When the ultrasonic wave goes through the interface of two different media, the reflection occurs, refraction, transmission and other physical phenomena can occur because of a large extent acoustic impedance difference between water and air, which can be used in this physical phenomenon, by monitoring the ultrasonic energy (output voltage) can be obtained if the extent of the presence of bubbles and bubble exists within the infusion tube. By measuring the penetration of ultrasonic energy, we detected air bubbles within the infusion line. Ultrasound can accurately detect air bubbles in the infusion line, which is the main method of detecting air bubbles for infusion pump.
