Warnings and cautions of ultrasonic probe

★The ultrasonic probe is a valuable device. It must be careful in the process of use. Avoid dropping, impact, or abrasion to transducers.

★When installing or removing the probe, first switch off the power and then operate it carefully.

★Avoid rapid and extreme temperature changes, as well as lengthy exposure to direct sunlight or a strong ultraviolet light source.

★Do not use sharp objects to penetrate the acoustic lens.Once the acoustic lens is damaged, the coupling gel is easy to enter the interior of the probe and damage the piezoelectric element.

★Do not soak transducer in any liquid above the recommended level as stated in the user manual for your system, please operate according to the manufacturer's instructions, otherwise it will lead to circuit failure or even burn out.

★Do not disinfect at high temperature, because the probe is equipped with piezoelectric ceramics, high temperature will weaken the effect.

★Before use, carefully check whether the housing and cable are damaged, so as to prevent the probe from high voltage injury.

★After the probe is used, the residual coupling gel on the probe must be wiped clean to prevent rats or other animals from gnawing the lens.

Knowledge point

Multi-frequency probe

Multi-frequency probe is a new development of pulse-echo transducer. The probe can send out several different ultrasonic pulses, so as to cover the near field with high-frequency ultrasound, the intermediate-frequency ultrasound to cover the transition zone between the far and near fields, and the low-frequency ultrasound to cover the far field. The unit multi-frequency probe is to bond multiple layers of piezoelectric ceramics (or polymer piezoelectric materials) to each other, and lead wires from the electrodes between each layer to obtain multiple frequency ultrasonic pulse emission through exciting different layers . The digital coding of the multi-frequency probe is simple but easy to lose the signal.
