Rencheng Repair Case: Bestson PA240 Probe Failure Repair
Release time:
2025-03-12 09:37
Machine Type:Baisheng Probe
Machine Model: PA240
1. Malfunction Phenomenon
Acoustic lens damage.
2. Fault Detection
The on-machine image is normal, the lens is damaged. Actual detection shows that PA240 128 array elements are normal, the capacitance is 450pf, elements 1-10 are missing, the capacitance is only 200pf, elements 120-128 are missing, the capacitance is only 200pf, the lens is damaged, the coupling agent has seeped in, and there is internal corrosion. It is recommended to replace the acoustic lens.
3. Fault Determination and Analysis
Long-term use has caused wear and tear on the acoustic lens, requiring replacement.
4. Fault Handling
The acoustic lens was replaced. After reinstallation and on-machine testing, the probe is in normal use.
5. Post-Repair Effect
6. Probe Maintenance and Care
(1) Handle with care
Ultrasonic probes must be handled with care during use to avoid impacts that could damage the internal chips. When finished using the probe, do not fold or tangle the probe connecting wires.
(2) Probe Plugging and Unplugging
In daily applications, when changing ultrasonic probes, always turn off the host 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 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 or disinfectants, it will directly corrode and accelerate the oxidation of the probe socket pins. In short, maintenance and care are important aspects of the actual medical equipment 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 extend the service life of the ultrasonic probe.
