Electromagnetic Compatability Standard For Medical Devices

Co-published with the IEEE Press, this book is a practical, hands-on guide to EMC issues for medical device designers and installers. It addresses electromagnetic interference and covers the basics of EMC design, physics, and installation, minimizing theory and concentrating upon the correct way to ground and shield. Covering EMC from the inside out, the book provides the basics of electronics, discusses and evaluates problems and common causes, and explores effective remedial techniques at three levels: circuit, box, and interconnect. It contains appendices that provide important reference material such as constants and conversion factors.

"Co-published by IEEE Press and Interpharm Press, Electromagnetic Compatibility in Medical Equipment is a practical, hands-on guide to EMC issues for medical device designers and installers. The book addresses electromagnetic interference and covers the basics of EMC design, physics, and installation, minimizing theory and concentrating upon the correct way to ground and shield." "Twelve detailed chapters cover EMC from the inside out, beginning with the basics of electronics. Problems and common causes are discussed and evaluated. Effective remedial techniques are explored at three levels - circuit, box, and interconnect. The book also contains several useful appendices that provide important reference material including key information resources to EMC publications, materials (e.g., common metals and shielding materials), and constant and conversion factors." "Electronic Medical Device Designers, Engineers, Technicians, and Managers will find this book of particular interest as will Medical Equipment Installers and Facility Engineers who handle medical equipment."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Abstract: A guide to evaluating electromagnetic immunity of medical devices against radiated radio-frequency (RF) emissions from common RF transmitters is provided in this recommended practice (e.g., two-way radios; walkie-talkies; mobile phones; wireless-enabled tablets, e-readers, laptop computers, and similar devices; RFID readers; networked mp3 players; two-way pagers; and wireless personal digital assistants [PDAs]). A comprehensive test or a guarantee is not provided by this protocol but, instead, a basic evaluation is given that can help identify medical devices that might be particularly vulnerable to interference from common RF transmitters. Existing or newly purchased medical devices can be evaluated by this ad hoc test protocol or the protocol can be implemented for prepurchase evaluation. This recommended practice applies to medical devices used in health-care facilities but can also be adapted to medical devices in home health-care or mobile health-care settings. It does not apply to implantable medical devices (e.g., pacemakers and defibrillators), transport environments such as ambulances and helicopters, or RF transmitters rated at more than 8 W of output power. Testing with transmitters greater than 8 W in health-care facilities is not recommended because of possible adverse effects on critical-care medical devices that are in use in nearby areas of the facility. Finally, in-band RF interference where the fundamental frequency of an RF transmitter overlaps with frequencies used by a hospital wireless network or monitoring or other medical device wireless links is not addressed by this recommended practice.

As the biomedical engineering field expands throughout the world, clinical engineers play an ever more important role as the translator between the worlds of the medical, engineering, and business professionals. They influence procedure and policy at research facilities, universities and private and government agencies including the Food and Drug Administration and the World Health Organization. Clinical engineers were key players in calming the hysteria over electrical safety in the 1970s and Y2K at the turn of the century and continue to work for medical safety. This title brings together all the important aspects of Clinical Engineering. It provides the reader with prospects for the future of clinical engineering as well as guidelines and standards for best practice around the world.

Recent Topics in Electromagnetic Compatability discusses several topics in electromagnetic compatibility (EMC) and electromagnetic interference (EMI), including measurements, shielding, emission, interference, biomedical devices, and numerical modeling. Over five sections, chapters address the electromagnetic spectrum of corona discharge, life cycle assessment of flexible electromagnetic shields, EMC requirements for implantable medical devices, analysis and design of absorbers for EMC applications, artificial surfaces, and media for EMC and EMI shielding, and much more.
