At present, the maintenance of medical equipment is a rather complicated work, many medical institutions have equipment sections, responsible for maintaining the safety and stability of equipment, but there are many problems that many equipment maintenance personnel do not understand or pay attention to. Here to popularize the maintenance and maintenance of medical equipment harness.

The first point: careful daily maintenance is essential to ensure the normal operation of instruments and equipment.

Daily maintenance seems simple, but many times it is not paid attention to, and it is easy to be ignored; But a lot of times big problems tend to accumulate from small problems. It is necessary to actively cooperate with clinical users and keep the surface of the instrument clean; Check whether the voltage and power supply are normal before use; During use, pay attention to observe whether the function of the instrument is normal and fill in the use record. Develop good habits in daily maintenance to avoid damage.

Second point: Equipment maintenance work, must be carefully handled, do not be careless.

When the equipment fails, it is necessary to collect and prepare the information before maintenance; Including the model, the factory number, the time of failure, the abnormal sound when the fault occurs, whether there has been a sudden power failure, and whether the instrument has moved.

Maintenance should pay attention to, in the process of disassembling medical equipment, pay attention to the order, do not use brute force to disassemble. Remove the fastening screws, small pieces, etc. can not be carelessly placed, to be classified and put away to avoid loss. After the maintenance of the equipment is completed, the installation is restored step by step in the reverse order, without spare parts. The damaged parts should also be marked and restored after replacement without error.

After the maintenance work is completed, the surface of the instrument should be cleaned, and the power supply should be switched on to see if it can work normally. The calibration instrument is restored to the normal working state, and then it is tried by the user to see whether the instrument is restored to the original working state, so as not to leave hidden dangers. After cleaning the site, check whether there are missing tools, etc., and fill in the maintenance log for future reference.

Protection engineers in the maintenance of the instrument, should always pay attention to do a good job of protection, whether it is leakage or cross infection and other problems, should pay attention to protection. Avoid unnecessary accidental injuries.

Third point: regular maintenance inspection, the problem is found as soon as possible, as soon as possible to solve.

Detailed preventive maintenance should include:

Appearance inspection: The appearance inspection first checks whether the buttons, switches, connectors and sockets of the instrument are loose and misplaced, whether the contact of the plug and socket is oxidized, rusted or poor contact, whether the power cord is aging, whether the heat dissipation and exhaust air are normal, whether the various grounding connections and pipeline connections are good.

Cleaning and maintenance: It is to clean the surface of the instrument and the internal electrical parts and mechanical parts, including cleaning the filter and related pipes, cleaning the plugs and sockets of the instrument, preventing poor contact, and lubricating the necessary mechanical parts.

Replacement of wearing parts: have reached the service life and performance decline, do not meet the requirements of the components or the requirements of regular replacement of the parts specified in the instruction manual to be replaced in a timely manner, to prevent possible fault expansion or cause the whole machine failure. In the case of insufficient battery charging, the relevant personnel should be urged to charge regularly and eliminate obvious and potential failures of the equipment.

Performance test calibration: test the voltage regulator value of each DC power supply, the voltage value or waveform of the test point in the circuit, and carry out the necessary calibration and adjustment according to the requirements of the manual to ensure that the technical indicators of the instrument meet the standard and ensure the quality of the instrument in medical diagnosis and treatment.

Safety inspection: 1, check whether the frame is firm, whether the mechanical operation is normal, and whether the connected parts are loose, off or broken. 2, check whether all kinds of leads, plugs, connectors, etc. are damaged, whether the grounding wire is reliable, whether the grounding resistance and leakage current are within the allowable limits.
