Common medical equipment fault diagnosis and maintenance skills
Common medical equipment fault judgment and maintenance skills involve multiple aspects. The following are some key steps and skills:
1. Fault judgment skills
Observation method
Indicator light observation: Check whether the indicator light of the equipment is working properly and whether there is abnormal flashing or extinguishing. This helps to preliminarily judge the status of the power supply, circuit or functional module.
Display screen observation: Check whether the display screen is clear and whether there are abnormal characters or images. This can reflect the operating status of the equipment and possible software or hardware problems.
Appearance inspection: Check whether the appearance of the medical device is intact and whether there is obvious damage or deformation, such as loose connection wires and broken shells.
Auscultation method
Listen carefully to the sound of the medical device when it is working to determine whether there is abnormal noise or vibration. This helps to identify wear, looseness or failure of mechanical parts.
Palpation method
Touch the surface of the medical device to feel whether its temperature is normal and whether there is overheating or overcooling. Overheating may indicate a problem with the heat dissipation system, while overcooling may be related to the power supply or refrigeration system.
Press the device gently to feel whether its vibration is normal and whether there is abnormal vibration or impact. This helps to judge the working status of the internal mechanical parts.
Instrument detection method
Use a special detector to detect various indicators of medical equipment, obtain detailed data analysis results, and compare them with normal parameters to determine whether the equipment has faults or performance degradation.
Inquiry method
By asking the on-site operator or patient, understand the entire process before and after the equipment fails, including the phenomenon of the equipment at the time, whether there are abnormal sounds, etc., which helps to quickly locate the fault point.
2. Maintenance skills
First outside, then inside
When performing fault inspection and maintenance, you should first start with external equipment, connecting wires, power supplies, etc., and consider internal faults after eliminating external factors.
Simple first, then complex
Prioritize solving simple and obvious faults, such as loose power plugs, blown fuses, etc., and then gradually investigate complex faults.
Power supply first, then circuit
Power supply failure is a common cause of medical equipment failure, so you should first check whether the power supply system is normal, including whether the power supply voltage, current, frequency and other parameters meet the requirements.
Step by step investigation
According to the circuit wiring, component distribution and technical information of the equipment, gradually narrow the scope of the fault and finally determine the fault point. Tools such as multimeters and oscilloscopes can be used for detection and measurement.
Replacement and debugging
For damaged parts, they should be replaced in time, and debugged and tested after replacement to ensure that the equipment returns to normal operation. During the debugging process, attention should be paid to the setting and adjustment of parameters to avoid causing new faults.
Pay attention to safety
When repairing medical equipment, the safety operating procedures should be strictly followed to ensure the safety of personnel and equipment. When disconnecting the power supply, unplugging the plug, etc., it should be ensured that the equipment has completely stopped working and is in a safe state.
Recording and summary
For each maintenance process, the fault phenomenon, maintenance steps, replacement parts and other information should be recorded in detail for future reference and summary of experience and lessons. At the same time, the maintenance records should be sorted and analyzed regularly to improve maintenance efficiency and quality.
3. Repair skills for specific equipment failures
Endoscope equipment: pay attention to the protection of the mirror, the cleaning and storage of the wires, the aging and replacement of the sealing rings, etc.
Magnetic resonance imaging equipment (MRI): regularly check the ambient temperature of the equipment space, clean the equipment room, remove metal objects in the magnet and on the coil of the bed, etc.
X-ray equipment: keep the temperature and humidity of the machine room appropriate, and regularly check the grounding and X-ray tube sheath conditions, etc.
In summary, fault diagnosis and maintenance of medical equipment requires the comprehensive use of a variety of skills and methods, while focusing on safe operation and record summary. By continuously improving maintenance skills and accumulating experience, medical equipment failure problems can be solved more effectively to ensure the smooth progress of medical work.
