Scientist invents ‘robot’ that kills Ebola virus


RECENTLY, in effort to eliminate Ebola
at the source, through use of innovative
disinfection technology, two “germ-
killing robots” were deployed from the
US to the JFK Hospital and ELWA
Hospital both in Monrovia, Republic of
Liberia, both hotspots of the Ebola
disease outbreak.
The robots, technically known as TRU-D
SmartUVC, were used to disinfect health
care environments where Ebola patients
are being treated.
Good Health Weekly gathered that TRU-
D is the only portable UV disinfection
device on the market with Sensor360
technology, which calculates the time
needed to react to room variables such
as size, geometry, surface reflectivity
and the amount and location of
equipment in the room and effectively
deliver a lethal dose of UV-C light during
a single cycle from a single, central
location in the room.
Ultraviolet light “It works by generating
ultraviolet light energy that modifies the
DNA structure of viral pathogens, like
Ebola, so that they cannot reproduce.
Viruses that cannot reproduce cannot
colonise and harm patients,” the
inventor, a tropical disease expert and
medical anthropologist Dr. Jeffery L.
Deal noted in an interview.
Deal and his colleague, Chuck Dunn,
President and CEO of TRU-D LLC,
respectively, spoke about the
importance of TRU-D to environmental
disinfection in “TRU-D has been
validated by more than 10 studies to be
99.99 percent effective in eliminating the
most common pathogens that can use
health care-associated infections.
After deploying germ-killing robots to
Liberia to aid in battle against the Ebola
Virus Disease, TRU-D SmartUVC inventor
traveled to the Ebola hotspots with UV
disinfection devices
TRU-D guarantees a pathogen-free
environment for patients and health
care staff. Deal, a Fellow in the Royal
Society of Tropical Medicine and
Hygiene, has been training hospital staff
to operate the devices in a number of
hospital environments and monitor
progress for successful disinfection.

“We developed TRU-D SmartUVC
technology to combat the devastating
effects ofhospital acquired infections,”
Deal said.
“Unlike many diseases, Ebola strikes
hospital workers more than any other
group, making it the ultimate hospital
acquired infection.”
With TRU-D, health care leaders in the
U.S., Canada, the U.K. and Saudi Arabia
are eliminating pathogens like Ebola,
Middle East Respiratory Syndrome,
MERS, influenza, norovirus, Clostridium
difficile, Methicillin-resistant
Staphylococcus aureus, MRSA, etc., in all
types of health care settings, including
isolation wards, patient rooms,
operating rooms, surgical suites,
intensive care units, emergency rooms,
public areas and ambulances.
“We know through extensive CDC-funded
research specific to TRU-D conducted by
thought leaders in epidemiology and
infection prevention that TRU-D is
effective at eliminating anypathogen by
delivering a precisely measured UVC
dose.
“As soon as we knew we could aid
struggling hospitals in Liberia, our team
came together and formulated a plan to
get TRU-D on the ground. More than 200
TRU-Ds have been deployed to disinfect
hospitals across the U.S. and
internationally.
Significance Between 10 and 15 percent
of Ebola cases have been among health
care workers. While most of this stems
from contact with the patient, concerns
exist that the physical environment can
retain active microbes and be a risk.
This device is used in the US
to eliminate the organisms that may still
reside on the walls, knobs, rails or any
other exposed surface in health care
settings. The robotic technology is
capable of making the Liberian hospitals
safer for the staff and for new patients.
Development
It was developed by a team of engineers,
physicians and industrial hygienists with
the purpose of decontaminating entire
rooms automatically
and eliminating concerns that a
contaminated surface was missed during
routine cleaning.
We use an ultra-efficient narrow
wavelength called UVC to flood the room
with germicidal energy. UVC dosage is
accurately measured and automatically
adapts to kill organisms, even in
shadowed areas.
UV disinfection technology and EVD
control This technology is designed to
prevent the spread of the disease
transmitted via contaminated surfaces
in health care environments and is not a
treatment or a cure. We believe that
prevention is the best medicine.
The U.S. Army tested this particular
wavelength against Ebola and found that
the measured dose TRU-D delivers
results in incredibly rapid destruction of
the virus with its pathogen-specific
dosing options.. We know it is perfect
for use in this critical setting.
Merits/demerits
Multiple studies have already been
published from U.S. and UK academic
facilities of TRU-D’s ability to
decontaminate rooms, almost always
testing it against organisms that are
much more difficult to kill in the
environment than Ebola is.
