How to select the right components to protect medical devices, users & patients

摘要

The requirements of where, why, what and how to use circuit protection devices in general, and in medical units in particular, is a complicated design challenge. There are many suitable protection components, some specific to a given circuit function and others with more general applicability. Each component brings a set of attributes that makes it a best fit-or at least a better one-in the different circuit and system locations requiring such protection. No single device will fit the multiple diverse system requirements, and so designers will end up using multiple protection approaches. In most cases, the many decisions regarding which devices to use and how best to do so are inherently complicated, and also subject to regulatory review. Designers should strongly consider asking for help from knowledgeable application engineers at the protection device vendor or their designated supplier (distributor). Their experience and expertise can reduce time-to-market, ensure a more thorough design and ease the path to regulatory approval.
