With the growing demand for medical electrical equipment for use in home environments, there is a greater emphasis on ensuring that these devices and equipment deliver the intended performance while being safe for patients, caregivers, and healthcare professionals. Knowledge of standards and the current regulatory changes governing these aspects enable manufacturers to make better decisions and work out potential design problems as early as possible.
In this whitepaper, we will discuss the main principles of IEC 60601-1 and how they apply to power supply design. We will also look at the evolution of the standard through to the 4th edition and provide an overview of medically-safe power solutions available for medical equipment designers and manufacturers. In addition, we will touch on several solutions by leading manufacturers like Cosel, NMB and Advanced Thermal Solutions.
