6. 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 connecting wires.
(2) Probe Plugging and Unplugging
When changing ultrasonic probes in daily applications, always turn off the main power. If the host 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 instantaneous high current. This 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 or disinfectants, it will directly corrode and accelerate the oxidation of the probe socket pins. In short, maintenance is an important task in the actual medical device maintenance process for ultrasonic probes, because the effectiveness and accuracy of the ultrasonic probe directly affect the efficiency of ultrasonic examination. Routine maintenance should be carried out regularly to reduce damage caused by human factors and extend the service life of the ultrasonic probe.
