Medical Device Shielding
Hospitals and medical facilities house hundreds of medical devices that require specific EMI / RFI shielding. These devices include magnetic resonance imaging (MRI), computed tomography (CT or CAT), Electromyography (EMG) and others that rely on shielding to function properly in their intended environment.
Importance of Shielding in Medical Devices
Medical devices are frequently used in the vicinity of other electronic equipment, and as a result, properly shielding these devices is critical in preventing electromagnetic interference. Interruption in medical device performance can be the difference between life and death.
Without proper EMI shielding, medical devices, including life-support systems and essential monitoring equipment are vulnerable to signal noise, damage, or total functional impairment.
Engineering for Safety: Medical Device Shielding
EMI shielding can be applied to any phase of medical device development. While best practice encourages Design Engineers for medical equipment to consider and incorporate shielding during development, there are many options for the addition of or improvement to existing shielding after a product has been tested, or may be in use.
As new technology and devices are being used both personally and professionally in healthcare settings, it is important to stay ahead of ever-evolving EMC Standards for medical use such as the IEC 601-1-2, EN 60601 or ANSI C63.18. Electromagnetic compatibility (EMC), emissions and immunity are all critical to the safe operation of devices and equipment.
Medical Device Shielding Resources
In this post, we’ll provide you with the resources you need for any commercial or military application that might need EMI/RFI protection for a generator.
A lot of engineers use the terms interchangeably, but project success with proper electromagnetic shielding is more easily achieved with a proper definition!
Definitions & Distinctions HEMP is defined as an instantaneous, intense electromagnetic pulse (EMP) field that can overload and disrupt from great distances electrical systems and microcircuits. It is generally assumed if one occurred it would be set off by a high altitude nuclear explosion; obtainable by missile flight1 or, more recently believed, from a satellite.…
5G (fifth generation) is the newest communication infrastructure and electronic device advancement to enable a multitude of faster, more functional, comprehensive technologies and human services available to everyone. 5G is used with mission critical communications, internet of things (IoT) and mobile broadband telecommunications. 5G Frequencies and Wavelengths The FCC recently granted 280 MHz from 3.70…
Wherever there is a window in a hardened enclosure, whether it’s in something as small as a handheld device or as large as a shipping container, there is the probability of EMI contamination. EMI shielded windows are designed to solve this problem. They allow for separation between the interior and exterior of a shielded unit…
Ventilator Systems & Medical EMC Shielding Medical facilities are one of the epicenters of the Covid-19 pandemic. Their capacity to treat infected patients with life-saving equipment like medical respirators is vital. Severe Covid-19 patients can develop a life-threatening condition called acute respiratory distress syndrome (ARDS) that requires ventilators to deliver smaller volumes of oxygen and…
Once you’ve determined that your systems or components need isolation from surrounding electromagnetic fields, or to block the transmission of additional signals, designing the appropriate enclosure is crucial. Our shielding design flow chart can help designers and engineers navigate the varied types of EMI/RFI shielding materials available to choose the right materials that meet your…
EMI / RFI Shielding For Medical Device Applications Take any average-sized hospital in the U.S. and count the number of electronic devices in use. According to the World Health Organization (WHO), that number averages over 10,000. Imagine all those separate life-saving devices – magnetic resonance imaging (MRI), computed tomography (CT or CAT), Electromyography (EMG) and…
Many engineers understand the basics of EMC, but those in the medical, telecom, defense, and manufacturing industries may not have the resources or personnel to fully integrate EMC into their products to meet the standards set by their industry. In response to this need, MAJR Products offers EMC consulting services to bring products from the…
