6. Probe Maintenance Tips

(1) Handle with care

Ultrasound probes must be handled with care during use to prevent impacts from damaging the internal chips. When the probe is not in use, do not bend or knot the probe connecting wires.

(2) Probe Plugging and Unplugging

In daily applications, when changing ultrasound probes, always turn off the main unit power. If the main unit is not powered off and not frozen, directly plugging and unplugging the probe may cause damage to the internal circuit board and crystals due to a momentary strong current. It will also accelerate the oxidation of the probe plug pins, directly affecting the normal use of the probe.

(3) Probe Cleaning and Disinfection

Avoid contact between the probe socket and disinfectant. If the probe socket is contaminated with cleaning agents and disinfectants, it will directly corrode and accelerate the oxidation of the probe socket pins. In short, in the actual maintenance process of medical ultrasound equipment, maintenance is an important task, as the effective accuracy of the ultrasound probe directly affects the efficiency of ultrasound examination. Regular maintenance should be carried out to reduce damage caused by human factors and extend the service life of the ultrasound probe.
