Opis

Design and Development of Medical Electronic Instrumentation fills a gap in the existing medical electronic devices literature by providing background and examples of how medical instrumentation is actually designed and tested. The book includes practical examples and projects, including working schematics, ranging in difficulty from simple biopotential amplifiers to computer-controlled defibrillators. Covering every stage of the development process, the book provides complete coverage of the practical aspects of amplifying, processing, simulating and evoking biopotentials. In addition, two chapters address the issue of safety in the development of electronic medical devices, and providing valuable insider advice.

Recenzje

"The book is user–friendly, accurate...and will be very useful to anyone with a basic understanding of circuit theory " ( Annals of Biomedical Engineering, June 2006)

"This reviewer will find this text a valued part of his library for the several areas extremely well elucidated. And talking with a few colleagues, the reviewer confirmed that this text will have wide appeal " (Biomedical Instrumentation & Technology, July/August 2005)

" details this application′s unique requirements and constraints, exploring with general discussion, schematic diagrams, representative waveforms, and typical–design photos." (EDN Online, January 12, 2005)

Master the building blocks of medical devices with this hands–on guide

This book provides a uniquely practical approach that enables readers to learn the design of medical electronic devices through the analysis of specific projects. Walking you through the building blocks of implementing medical devices, Design and Development of Medical Electronic Instrumentation addresses the practical aspects of amplifying, processing, simulating, and evoking biopotentials. It provides real–world projects that range from simple biopotential amplifiers all the way to a computer–controlled defibrillator. Anyone with a basic understanding of circuit design and electrical engineering mathematics and experience in electronic prototype construction will find these projects accessible. Chapters discuss:

• Biopotential amplifiers, including a refresher on the origin and acquisition of physiological electrical signals
• Spectral content of biosignals, filter design, and the selection of frequency ranges for biopotential amplifiers
• Design of safe medical device prototypes
• International regulations and design practices for electromagnetic compatibility of medical devices
• Data acquisition, smart sensors, analog–to–digital conversion, and high–resolution spectral analysis of physiological signals
• Artificial signal sources for simulating physiological events
• Principles, clinical applications, and design of excitable tissue stimulators
• Design of cardiac pacemakers and defibrillators, including a refresher on the electrophysiology of the heart, its conduction deficiencies, and arrhythmias

With access to an ftp site that contains the software and information needed to successfully complete the projects outlined, plus a special epilogue on how to bring a medical device to market, this book will help one quickly master the essentials of medical device design and build sophisticated instrumentation for a broad range of purposes.
