Laboratory equipment is one of the important resources of the laboratory, and an important guarantee for the specific report of the laboratory! Whether it is now, in the past and in the future, the maintenance of equipment and equipment is a rather complicated task, in order to ensure the test data In addition to the periodic verification, calibration, and periodical verification of the instrument and equipment, the accuracy and reliability of the instrument and equipment also need to do the daily maintenance of the instrument and equipment.
Routine maintenance seems simple, but in many cases it is not valued by others, and it is also the easiest to ignore; but in many cases big problems are often accumulated by small problems. It is necessary to actively cooperate with clinical users to 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 record. Develop good habits during daily maintenance to avoid damage.
When the equipment fails, information collection and preparation work must be done before repair; including model, factory number, time of failure, abnormal sound when failure occurs, whether there is a sudden power failure, whether the instrument has been moved, etc.
During maintenance, attention should be paid to the sequence of disassembling medical equipment, and do not use brute force to disassemble it. The disassembled fastening screws, small parts, etc. should not be placed randomly, and should be placed separately to avoid loss. After the equipment is repaired and installed, it will be restored step by step in the reverse order, with no extra parts. Damaged parts should also be marked and restored after replacement, without making mistakes.
After the repair work is completed, clean the surface of the instrument and turn on the power to see if it can work normally. Calibrate the instrument and restore it to its normal working state, and then give it to the user to try it out to check whether the instrument returns to its original working state, so as not to leave hidden dangers. Finally, clean the site, check for missing tools, etc., and fill in the maintenance log for review.
When the maintenance engineer is repairing the instrument, he must always pay attention to the protection work, whether it is leakage or cross-infection, etc., they must pay attention to protection. Don't cause unnecessary accidental injury.
The detailed preventive maintenance content should include: visual inspection, cleaning and maintenance, replacement of wearing parts, functional inspection, performance test and calibration, and safety inspection;
(1) Visual inspection:
Visual inspection firstly check whether the buttons, switches, connectors and sockets of the instrument are loose or misplaced, whether the contacts of the plugs and sockets are oxidized, rusted, or have poor contact, whether the power cord is aging, whether the heat dissipation and exhaust air are normal, and various grounding connections and Whether the pipe connection is good.
(2) Cleaning and maintenance:
Is to clean the surface of the instrument and the internal electrical parts and mechanical parts, including cleaning the filter screen and related pipes, cleaning the related plugs and sockets of the instrument, preventing poor contact, and lubricating the necessary mechanical parts.
(3) Replace the wearing parts:
Components that have reached their service life and performance degradation, substandard components or parts that require regular replacement as specified in the instruction manual should be replaced in time to prevent possible failures from expanding or causing complete machine failure. When the battery is under-charged, the relevant personnel should be urged to charge regularly to eliminate obvious and potential equipment failures.
(4) Functional inspection:
Turn on and check whether the indicators and indicators are normal. By adjusting and setting each switch and button, enter each function setting to check whether the basic functions of the device are normal. Through the simulation test, check whether the alarm functions of the equipment are normal.
performance test calibration:
Test the voltage value of each DC power supply, the voltage value or waveform of the test point 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 .
1.Check whether the frame is firm, whether the machine is running normally, and whether the connecting parts are loose, falling off or broken.
2. Check whether various leads, plugs, connectors, etc. are damaged, whether the grounding wire is firm, whether the grounding resistance and leakage current are within the allowable limits.
