At present, the maintenance of medical equipment is a very complicated work, and there are many problems that many equipment maintenance personnel do not understand or pay attention to. Here again, we will popularize the maintenance and maintenance of medical equipment to everyone.
First, meticulous daily maintenance is essential to ensure the normal operation of equipment.
Routine maintenance seems to be simple, but it is not valued by people in many cases, and it is also the most easily overlooked; but in many cases, big problems are often accumulated from small problems. Keep the surface of the instrument clean; check whether the voltage and power supply are normal before use; observe whether the function of the instrument is normal during use and fill in the use records. Develop good habits during daily maintenance to avoid damage.
Second, equipment maintenance work must be handled carefully and not carelessly.
When the equipment fails, it is necessary to collect and prepare information before maintenance, including the model, factory number, time of the failure, whether there is any abnormal sound when the failure occurs, whether there has been a sudden power failure, and whether the instrument has been moved.
During maintenance, it should be noted that in the process of disassembling medical equipment, attention should be paid to the sequence, and do not use brute force to disassemble it. The removed fastening screws, small pieces, etc. should not be placed randomly, but should be sorted and stored to avoid loss. After the maintenance of the equipment is completed, when installing, it will be restored step by step in the reverse order, and there will be no extra accessories. Damaged spare parts should also be marked and restored to their original state after replacement, without making mistakes.
After the maintenance work is completed, clean the surface of the instrument, turn on the power supply, and see if it can work normally. Calibrate the instrument, return to normal working state, and then give it to the user to try it out to check whether the instrument returns to the original working state, so as to avoid hidden dangers. Finally, clean up the site, check for missing tools, etc., and fill in the maintenance log for review.
The maintenance engineer should always pay attention to the protection work when repairing the instrument, whether it is leakage or cross infection, etc., they must pay attention to protection. Do not cause unnecessary accidental injury.
The third point is regular maintenance and inspection, and problems are discovered and solved as soon as possible.
Detailed preventive maintenance should include:
Visual inspection:
Visual inspection First check whether the buttons, switches, joints and sockets of the instrument are loose and misplaced, whether the contacts of the plugs and sockets are oxidized, rusted or poorly connected, whether the power cord is aging, whether the heat dissipation and exhaust are normal, and whether various grounding connections and Whether the connection of the pipes is good.
Cleaning and maintenance:
It is to clean the surface and internal electrical parts and mechanical parts of the instrument, including cleaning the filter screen and related pipes, cleaning the relevant plugs and sockets of the instrument, preventing poor contact, and lubricating the necessary mechanical parts.
Replacing wearing parts:
The components that have reached the service life and the performance decline, and the components that do not meet the requirements or the accessories that are required to be replaced regularly as specified in the instruction manual should be replaced in time to prevent the expansion of possible failures or cause the failure of the whole machine. If the battery is insufficiently charged, the relevant personnel should be urged to charge it regularly to eliminate the obvious and potential faults of the equipment.
Functional check:
Turn on the machine to check whether each indicator light and indicator are normal, and enter each function setting by adjusting and setting each switch and button to check whether the basic function of the device is normal. Through the simulation test, check whether the alarm functions of the equipment are normal.
Performance Test Calibration:
Test the voltage regulation value of each DC power supply, the voltage value or waveform of the points to be tested in the circuit, and perform necessary calibration and adjustment according to the requirements of the manual to ensure that the technical indicators of the instrument meet the standards and ensure the quality of the instrument in medical diagnosis and treatment. .
Security check:
1. Check whether the frame is firm, whether the mechanical operation is normal, and whether the connecting parts are loose, falling off or cracking.
2. Check whether various leads, plugs, connectors, etc. are damaged, whether the grounding wire is reliable, and whether the grounding resistance and leakage current are within the allowable limits.
