Napa, Calif. (April 26, 2017) –Queen of the Valley Medical Center has taken a leap into the future, using
two innovative germ-zapping robots to destroy deadly pathogens and kill
multi-drug resistant organisms that cause hospital acquired infections.
The two robots, named Stefan and QVR2 by Queen of the Valley Medical Center
caregivers, use Full-Spectrum™ pulsed xenon ultraviolet (UV) light
to quickly destroy harmful bacteria, viruses, fungi and bacterial spores
in hard-to-clean places.
The portable disinfection system is effective against pathogens, including
Clostridium difficile (C. diff), norovirus, influenza, Ebola and methicillin-resistant
Staphylococcus aureus, better known as MRSA. The robots are being used to disinfect surgical
rooms, the ER, patient rooms and more.
“We are excited to use the Xenex system to help us achieve our goal
of zero infections. This investment is important and underscores our commitment
to patient care and the communities we serve,” said Larry Coomes,
The disinfection system works by pulsing xenon, an inert gas, at a high
intensity in a xenon ultraviolet flashlamp. This produces intense ultraviolet
C (UVC) light which penetrates the cell walls of microorganisms, including
bacteria, viruses, mold, fungus and spores. Their DNA is fused, rendering
them unable to reproduce or mutate, effectively killing them on surfaces
without contact or chemicals. Each treatment takes about five minutes,
or approximately 25 minutes per room.
The robot has been tested and proven using independent lab verification
and has been credited by health care facilities across the U.S. for helping
them reduce their infection rates significantly.
Queen of the Valley began using the Xenex robot early in 2016. By the second
half of 2016, the Xenex cleaning program was fully in place, with environmental
services staff trained to consistently use the Xenex machine as part of
the terminal cleaning process. From July 2016 to December 2016, the Queen
decreased rates of C. Diff by 47.3 percent, when compared to the same
period in 2015.
More than 300 hospitals, Veterans Affairs and DoD facilities in the U.S.,
Canada, Africa and Europe are using Xenex robots, which are also in use
in skilled nursing facilities, ambulatory surgery centers and long term
acute care facilities.
