First, careful daily maintenance is essential to ensure the normal operation of instruments and equipment.

　　日常维护看似简单，但很多时分并不被人注重，也是容易让人忽略的；但很多时分大的问题常常是由小的问题积聚下来的。要做到与临床运用人员积极配合，坚持仪器表面清洁；运用前做到检查电压、电源能否正常；运用过程中留意观察仪器的功用能否正常并填写运用记载。在日常维修时就养成好的习惯，避免损坏事情发作。

　　Daily maintenance seems simple, but a lot of time is not paid attention to, and it is the most easily ignored; but many time-consuming problems are often accumulated by small problems. It is necessary to actively cooperate with the clinical operators, adhere to the cleaning of the instrument surface, check whether the voltage and power supply are normal before use, pay attention to observe whether the function of the instrument is normal during use and fill in the use records. Develop good habits in daily maintenance to avoid damaging things.

　　第二点，设备维修工作，一定要认真处置，不要马虎大意。

　　Second, equipment maintenance must be handled carefully and not carelessly.

　　医疗仪器设备发作缺点时，要做好维修前的信息搜集、准备工作；包括型号、出厂编号，缺点呈现时间，缺点呈现时有无异常声响，能否发作过突然停电，仪器有没有移动过等问题。

　　In case of any defect of medical instrument and equipment, information collection and preparation before maintenance shall be done well, including model, factory number, defect presentation time, whether there is any abnormal sound when the defect is presented, whether there is sudden power failure, whether the instrument has moved, etc.

　　维修中应当留意，在拆卸医疗设备的过程中，要留意先后次第，不要用蛮力强行拆卸。拆下来的紧固螺丝、小件等不可随手乱放，要分类放好，避免丧失。设备维修完成后，安装时，再按相反的次步一步恢恢复样，没有多余的配件。损坏的零配件，也要作好标志，改换后恢恢复样，不要呈现差错。

　　Attention should be paid to the maintenance. In the process of dismantling the medical equipment, attention should be paid to the order in which the equipment is dismantled. Do not use brute force to forcibly dismantle it. The removed fastening screws, small pieces, etc. shall not be placed at random. They shall be placed in categories to avoid loss. After the equipment is repaired and installed, the samples shall be recovered step by step according to the opposite steps, without redundant accessories. Damaged parts shall also be marked, replaced and restored without any error.

　　维修工作完成后，要清洁仪器表面，接通电源，看能否正常工作。校正仪器，恢复正常工作状态，然后交由运用人员试用一下，查看仪器能否恢恢复工作状态，以免留下隐患。清算现场，检查有无遗漏工具等，并填写维修日志留备查看。

　　After the maintenance work is completed, clean the surface of the instrument and connect the power supply to see whether it can work normally. Calibrate the instrument and restore it to normal working condition, and then submit it to the operator for trial to see whether the instrument can restore to working condition, so as to avoid potential hazards. Finally, clear the site, check whether there are missing tools, etc., and fill in the maintenance log for review.

　　维修中的防护工程师在维修仪器时，要时辰留意做好防护工作，无论是漏电还是交叉感染等问题，都要留意防护。不要呈现不用要的不测伤害。

　　When maintaining the instrument, the Protection Engineer shall pay attention to the protection work at all times, and pay attention to the protection no matter the leakage or cross infection. Don't show unexpected damage that you don't need.
               

　　第三点，定期保养检查，问题尽早发现，尽快处置。

　　Third, regular maintenance and inspection, problems found as early as possible, as soon as possible.

　　外观检查:

　　Appearance inspection:

　　外观检查检查仪器各按钮、开关、接头插座有无松动及错位,插头插座的接触有无氧化、生锈或接触不良,电源线有无老化,散热排风能否正常, 各种接地的衔接和管道的衔接能否良好。

　　For appearance inspection, firstly, check whether the buttons, switches and connector sockets of the instrument are loose and misplaced, whether the contact of the plug and socket is oxidized, rusted or poor, whether the power line is aging, whether the heat dissipation and air exhaust are normal, and whether the connection of various grounding and pipeline is good.

　　清洁保养:对仪器表面与内部电气部分、机械部分中止清洁,包括清洗过滤网及有关管道,对仪器有关插头插座中止清洁, 防止接触不良,对必要的机械部分中止加油润滑。

　　Cleaning and maintenance: stop cleaning the instrument surface, internal electrical part and mechanical part, including cleaning the filter screen and relevant pipes, stop cleaning the relevant plug and socket of the instrument, to prevent poor contact, and stop lubricating the necessary mechanical part.

　　改换易损件:对已抵达运用寿命及性能降落,不合恳求的元器件或运用说明书中规则的恳求定期改换的配件要中止及时地改换,预防可能发作的缺点扩展或构成整机缺点。对电池充电缺乏的情况要敦促有关人员中止定期充电, 扫除设备明显的和潜在的各种缺点。

　　Replacement of vulnerable parts: for the parts that have reached the service life and performance degradation, and are not in conformity with the requirements or the parts that are required to be replaced regularly according to the rules in the operation manual, the replacement shall be stopped in time to prevent the expansion of possible defects or the formation of the whole machine defects. In case of lack of battery charging, relevant personnel shall be urged to stop regular charging and eliminate obvious and potential defects of the equipment.
