The principle of "easy first, difficult later" for troubleshooting medical equipment failures

c Firstly, conduct a 5-minute external inspection: check the power supply voltage, socket contact, replace suspicious consumables such as electrode pads and conduits, and re plug and unplug critical interfaces. If the problem is not resolved, conduct software troubleshooting, such as restoring factory settings (requiring parameter backup) or checking for abnormal parameters. Finally, hardware testing is carried out using modular isolation method to locate the faulty unit, and professional tools are used to test the circuit parameters. For example, if the blood oxygen value of a monitor fluctuates, adjusting the probe position first, then checking the filtering mode, and finally detecting the blood oxygen module circuit board can efficiently solve the problem.
