5. Probe Maintenance

(1) Handle with care

Ultrasonic probes must be handled with care during use to avoid impacts that damage the internal chips. When finished using the probe, do not fold or tangle the probe connection wires.

(2) Probe Plugging and Unplugging

When changing ultrasonic probes during daily use, be sure to turn off the main power. If the host is not powered off and is not frozen, directly plugging and unplugging the probe may cause damage to the internal circuit board and crystal due to a momentary surge of 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, maintenance and upkeep are important aspects of the actual medical device maintenance process for ultrasonic probes, as the effective accuracy of the ultrasonic probe directly affects the efficiency of ultrasonic examinations. Regular maintenance should be carried out to reduce damage caused by human factors and prolong the service life of the ultrasonic probe.
