Shielding of an EMG Machine Utilizing a
Conductive Enclosure
Using the MED-E-ShieldTM conductive enclosure
we will show you the shielding methodology and test in which an
Electromyography (EMG) Instrument is shielded from harmful Electromagnetic
and Radio Frequency Interference (EMI/RFI) emissions. Click to download the full case study!
What is MED-E-ShieldTM?
MED-E-ShieldTM is best described by
our tag line: Mobile
Enclosures for Diagnostic Equipment. That
is precisely how we named our product! The M E D – E is simply
an acronym for the tag line! Add the fact that these enclosures
are specifically designed to shield out harmful Electromagnetic
Interference (EMI) as well as Radio Frequency Interference (RFI),
and you have a concise answer to your query! But there is far
more to this unique product!

This
product is mobile or portable by design. The proprietary design
of the aluminum exoskeleton allows for quick, easy assembly with
the use of one (1) provided tool; a specially designed "hex"
key. Two people with little to no experience can easily have
the aluminum frame completely assembled in 5 to 10 minutes! It
is this aluminum structure that allows the shielded enclosure
to hang in space as a secure environment in which to operate
your electronic equipment. Mobility is an important feature of
our product. This allows the option to keep the shielded enclosure
in place for long periods of time due to the durable construction
of the unit, or to move the secure room as needs dictate. Mobility
gives the owner complete control over where they place this secure
environment as well as the expense to achieve that end. The cost
of a "permanent" shielded room, such as an MRI room, can easily
be 10 to 20 times the cost of our Mobile
Enclosure for Diagnostic Equipment.
Our shielded enclosure or "secure room" is also unique in many
other ways. It is constructed of an extraordinary combination
of materials and fabrics that allows for flexibility and compression
while providing a barrier to EMI and RFI intrusion. The fact
that this is a soft enclosure makes it possible to fold it down
into a much smaller size, again for portability. While there
are many companies that build MRI rooms as well as hard construction
shielded rooms, there are few, if any, that have a flexible portable
secure structure such as MED-E-ShieldTM! Several companies
provide mobile shielded enclosures for temporary military command
posts but again, hardly any provide a soft solution that can
be assembled and disassembled as quickly as MED-E-ShieldTM.
These exceptional materials are also responsible for the shielding
effectiveness of the enclosure. Beginning with the fabric itself,
the entire design is conductive and "catches" the EMI
and RFI and takes them to ground. The fabric is flexible nylon
that has been plated with silver. Silver is highly conductive
making it an excellent path on which the electromagnetic and
radio frequency waves can travel rather than continuing in free
space. Silver is also good for the medical environment as it
has antimicrobial properties. Proprietary manufacturing techniques
all combine help to provide a
"sealed" environment and attenuate the EMI/RFI.
Other
materials such as conductive EMI Ventilation Panels, optional
shielded air conditioning or fan, EMI Windows and an EMI power
filter box round out the components that make MED-E-ShieldTM the
most effective portable shielded enclosure on the market today!
