Analysis of Electrolyte Analyzer Failure

Advanced instruments constantly enter the various departments of the hospital. In addition to the rigorous work attitude and skilled manipulative skills of the operators, it is particularly important to be good at observing, discovering, and correctly handling problems that occur during the use of the instrument. Any instrument in use will inevitably have different problems and faults. In addition to regular maintenance, maintenance, timely detection and effective handling of problems in the use of the instrument, it is particularly important for the service life of the instrument, and it is also a condition to ensure the quality of work. .

The instruments used in our department must carry out the necessary calibration and quality control before use every day. However, it was found that some instruments showed deviations in the results of the test. At this time, the instrument was calibrated or calibrated again, and the results were changed.

Analyze the reason: If the instrument is used for too long or the time is too long, all the components of the instrument can be aged, which will make the instrument fatigued. This will cause the stability of the instrument to decline, resulting in drift of the result and affecting the repeatability of the result.

Through analysis, it is suggested that if some instruments need to be used for a long period of time, they cannot be calibrated before the instrument is used every day. Therefore, the problem can be solved without problems. If problems arise, do not ignore the excessive specimens, the continuous use of the instrument, the fatigue of the instrument, and the aging of the components. It will also affect the results to varying degrees, and it will not reflect the true value very well. The appearance of some phenomena is not directly related to the maintenance and maintenance of the instrument. The problem of aging components of the instrument is unavoidable. This problem was confirmed when using the E-500 Electrolyte Analyzer. It should be noted that if the instrument is used for too long and the number of specimens is too large, the number of calibrations must be increased halfway to ensure the correctness and reliability of the results.
