METHODS OF ELIMINATING FAULTS IN MEDICAL EQUIPMENT AND ELECTRICAL SAFETY

Аннотация

One of the most important issues related to the use and elimination of electronic medical equipment for a medical worker is its electrical safety. The patient, due to various reasons (detoxification of the body, the effects of anesthesia, weakness, the presence of electricity in the body, i.e. direct connection of the patient to the electrical circuit, etc.), is in a particularly dangerous electrical environment compared to a healthy person. To prevent electrical hazards, it isnecessary to observe safety precautions. Keywords: Electrical hazard, electrical circuit, electrical network, insulation, electrical medical devices, electrodes, resistance. Medical workers working with electronic medical equipment are also exposed to electrical hazards. Electrical networks and technical systems usually provide electrical voltage. Troubleshooting is the key to identifying problems and implementing the correct maintenance, which will return the device in question to service as soon as possible. Troubleshooting requires knowledge of troubleshooting techniques and a thorough understanding of the theory of operation, structure, and proper use of the device in question. In general, troubleshooting has moved from component-level diagnostics to broader or assembly-level diagnostics. Circuit designs are using fewer and more discrete components, andreplacing individualICs isoften difficult orimpossible. Manufacturers’ service information often does not include component-level diagrams, descriptions, or parts lists, which makes it difficult to get down to the component level. Some electronic systems can still be repaired and repaired at the component level, so these skills should not be neglected. Step zero can be used to determine whether the device is covered underany warranty or service agreement. The first step in troubleshooting is to gather as much information about the problem as possible. This includes asking anyone who is using the device about the conditions that existed when the error occurred. Is the device making noises, smells, or smoke? Are there 98,7:ROTCAFTCAPMI.SECNEICS LACIDEM,5202, yraurbeF,5emuloV gro.srehsilbupcimedaca.www any codes or error lights? What accessories were used with the equipment? If possible, get theaccessories! Was there anything else unusual before the malfunction occurred? What other equipment was beingused at thetime? The second step involves reviewing the device's information. This may be something that you know almost automatically about common problems, or it may be something you've never seen before. If there is a service manual, you can consult it. On the other hand, service manuals may contain very littleuseful information fortroubleshooting. The third step is to try to reproduce the problem. Some problems occur from time to time, and just as your car never makes that funny noise when you take it in for repair, so too will failures occur from time to time when testing a device in a lab. You should try to recreate the conditions under which the failure occurred, as they are known to occur. Patience and a methodical approach will help achieve this goal, and some techniques come only with experience. It may not be possible to reproduce the problem. The device may not work at all, or it may continue to work without apparent problems. In the second case, you can decide whether toreturn thedevice toservice ornot withoutdoing anything further. Step four is to inspect the inside of the unit for damage, which can be a good indication that it has been damaged (even if the end user denies this possibility), and then you should look for internal damage. Carefully inspect the exterior of the unit for signs of damage, liquid ingress, overheating, or deterioration. Physical shock can cause heavy components such as transformers to be pulled out of their normal positions, and liquids entering the unit can leave obvious signs of corrosion or shrinkage. Some units may have internal fuses that can bechecked for continuity. Replacing a blown component may solve the problem, but it is often only a symptom of an underlying problem. Sometimes replacing the component and turning the unit on can provide additional information if the bad component is not actually the problem. Service manuals can have good troubleshooting guides that take you methodically through the system, checking for various things like voltage or waveforms at test points, or looking for specific answers from thedevice. 98,7:ROTCAFTCAPMI.SECNEICS LACIDEM,5202, yraurbeF,5emuloV gro.srehsilbupcimedaca.www If there is no useful troubleshooting information available, you may need to work through your own circuit. If possible, identify the power source and power supply. Check the voltages - these may be marked on the circuit boards, or you can make an educated guess as to what voltages should be at various points in the circuit. Check the continuity of the switches, as well as the power supply transformer. If it is not getting power from the
