The regular maintenance of medical endoscope equipment is generally completed by the instrument keeper in cooperation with the engineering and technical personnel. It is an organized and planned maintenance measure that is carried out in a continuous cycle, which is conducive to the search after failure. The content and time of regular maintenance can be divided into three levels.
(1) One guarantee: it can generally be carried out once a month to a quarter. In addition to the daily maintenance of the factory, the casing can be disassembled to remove dust, dirt and foreign matters, tighten screws and add lubricant; Check the service devices and components for wear, deformation, ablation, breakdown, looseness, moisture, aging, poor grounding, etc; Check the power supply voltage and ripple of each group, and check the operation and contact of high-voltage components.
(2) Second insurance: generally, it can be carried out once every six months to once a year. In addition to the first guarantee, it can test, correct and measure the sensitivity and accuracy of each instrument and operation control system on the console of the whole machine, replace the expired loss products such as the insulation of the high-voltage generator, systematically detect the voltage and waveform of each test point in the circuit and do the pull bias test.
(3) Three Guarantees: generally, it can be carried out once every 2-4 years: in addition to the second guarantee, the whole machine can be disassembled for cleaning and maintenance if necessary. The components that exceed the service life shall be replaced or repaired as much as possible. It is entirely possible to thoroughly debug the instrument and restore its working accuracy and performance to reach or exceed the level of the new machine.
In all departments of the hospital, the use of medical endoscopes is strict, and the requirements of endoscopes on the use environment: the indoor environment is mainly dark room environment to avoid direct strong light. The operation starts to turn off the fluorescent lamp and use shadowless lamp for lighting. Before operation, the indoor temperature is maintained at 22 ℃ ~ 25 ℃, the humidity is about 50%, acid, alkali and steam prevention. Avoid the interference of strong current and electromagnetic field. During the operation, the voltage shall be stable, and the continuous voltage regulator shall maintain the voltage of 220V to avoid damaging the precision instrument.
Medical endoscope has promoted the continuous development of medical cause in different periods. In the future, with the continuous progress of electronic technology and other science and technology, I believe its technology will have wider and deeper development.
