Effects on the human body: Body tissues affected by extremely high radio frequency energy may suffer severe thermal damage. As in many other fields, the number and complexity of Machining Taiwan in hospitals and other medical environments has increased year by year. As we all know, the human nervous system can also process very low-intensity electrical signals. Few people study the influence of electromagnetic fields on human nerves and control systems, which leaves a lot of room for future research.
Since all digital signals do have a very large bandwidth, their increasing use will cause electromagnetic radiation in almost all frequency ranges, which may affect most electronic devices and humans. Nevertheless, fortunately, the number of reported incidents of EMI (electromagnetic compatibility) problems does not seem to increase. This may be because most manufacturers and designers of Medical Machining Taiwan have a good understanding of EMC. Pacemakers are a typical example. Over the years, their Machining Taiwan design in terms of compactness and resistance to radio frequency interference has been greatly improved.
Healthcare engineering: Is electromagnetic interference (EMI) a problem in the healthcare environment? Although electrical interference in hospitals is generally regarded as a minor annoyance, Machining Taiwan records indicate that equipment failure due to electromagnetic interference (EMI) has caused casualties. Some examples are as follows:
o In 1992, a patient who was installed on a monitor defibrillator in an ambulance died because of emi radio interference from the ambulance causing the machine to fail to work (1).
o In 1987, the patient monitoring system failed to sound an alarm due to interference; two patients died as a result.
o In 1993, a patient with a pacemaker developed ventricular fibrillation shortly after being scanned by a metal detector outside the courtroom.
Today, pacemakers are very reliable, but they can still fail under extreme conditions. In patients undergoing electrosurgery and other patients with mobile phones in their chest pockets, the pacemaker failed, a few centimeters from the pacemaker lead. EMI comes from mobile phones or police intercoms, causing the wheelchair to drive by itself and its occupants into traffic. Due to the use of modern communication equipment and the use of the latest digital processing technology for most equipment, the use of spectrum is increasing, so guidelines for emission standards need to be formulated. Without increasing the cost of the product, the degree of stray radiation of any equipment should be limited to the possible range.
Various government and non-government agencies must coordinate and standardize permitted radiation limits at the national and international levels. The Machining Taiwan story is adapted from real events; accident reports in the United States in the early 1990s prompted the Food and Drug Administration (FDA) to investigate the Machining Taiwan issue and recommended that manufacturers change the design to provide at least 20V/m of EMI immunity. Wireless operators typically raise or lower towers, increase ratios, or change system configurations to eliminate service problems. These methods will not work if electromagnetic interference occurs. A well-designed shield system can provide a cost-effective and long-lasting solution.
