An unexpected surge of medical devices and health-care needs, new challenges in controlling high-frequency electromagnetic interference (EMI) in hospitals

2020/11/17 > Back



Hospitals are facing third wave of Covid-19 outbreaks, as well as the coming winter flu, are clogged with people and medical devices. When people and machines in the hospital can only concentrate in the same area, the electromagnetic interference (EMI) are more prevalent in the environment.

There are two categories of medical devices that are most prone to electromagnetic interference: electrical equipment and IVD (in vitro diagnostic)devices, especially MRI/Ventilators/Electrosurgical generator/Physiotherapy device etc. which can have very strong electromagnetic interference.

All of the above devices must pass EMC standards IEC / EN 60601-1-2 and CISPR 11 / EN 55011 to meet the safety requirements, although there is no literature indicates that the electromagnetic wave generated from these device will jeopardize patients, but now hospitals have already noticed the problems, especially those devices set in a crowded or confined space.

Since many countries around the world formulate different EMC regulations and directly affect whether they can be sold or used in the country, one of the most important tasks for engineer in the design verification & validation of medical devices is to be EMC certified. Regulations vary from country to country, and the credibility of the laboratory varies widely, such as the U.S. FDA (U.S. only, for diagnostic devices) is the most difficult, followed by UL 60601-1 (no designated laboratory, can be applied for through UL or TUV) and EU60601-1. If you can comply with these EMC standards, it will not be too hard for passing other countries EMC regulations.

Our EMC/EMI filters has been applied to many kinds of medical devices like ventilators, MRI, hemodialysis machine, infusion pump or remote health monitoring system, it makes medical devices more immune to electromagnetic interference signals present in the environment and also can be customized according to different EMC regulations or requirements.
