Vioguard’s self-sanitising computer keyboard for use in healthcare settings is said to be the first FDA-cleared computer keyboard to use the germicidal properties of ultraviolet light (UV-C) to clean its surfaces automatically. UV-C is a proven killer of flu, MRSA, and other harmful viruses and germs.
“We're very pleased with the FDA clearance, which substantiates our medical claims and allows hospitals and clinics to make use of this new tool,” said Larry Ranta, president and CEO of Vioguard, which is based in Kirkland, WA in the US. “Conventional computer keyboards have been identified as a key point of transmission of viruses and bacteria, especially within the medical setting. The Vioguard keyboard takes the guesswork out of sanitisation efforts, reduces labour costs, and helps fight the spread of harmful and often deadly superbugs.”
Based on independent laboratory testing, Vioguard has shown that the UV-C light generated by the keyboard's two 25-watt germicidal fluorescent lamps killed a minimum of 99.99% of harmful bacteria and viruses, including E. coli, MRSA, and other pathogens.
The keyboard has the look and feel of a standard notebook keyboard, and requires no software or special hardware to function. A powerful microprocessor controls UV exposure, operation of the sensor, and monitors safety interlock switches and lamp status.
On a user-triggered or predetermined basis, the keyboard automatically retracts into its own clean, light-tight enclosure. It is then safely flooded with high power germicidal UV light. By waving a hand within inches of a built-in motion sensor, the motorised keyboard drawer quietly opens and presents a completely sanitised keyboard and touchpad.
According to the US Centers for Disease Control (CDC), healthcare-associated infections (HAIs) affect more than 1.7 million patients in the US each year, with 12% of clinical MRSA infections being community-associated.
Vioguard’s VP of sales and marketing, Brandon DeCuir, said the company is in the process of setting up distribution for the keyboard across Europe.
