Disinfection of a real clinical setting using UV222™



In collaboration with the Lung Department of Aarhus University Hospital, UV Medico has validated the disinfection efficacy of UV222™ lamps, and the benefits of their use in healthcare settings, as a safe and improved approach for disinfection of occupied spaces.

We have measured the presence of bacteria in both periods and found that there are significantly fewer bacteria when the lamp is switched on.

At the lung clinic, many patients come with a low immune system and thus a high risk of infection. This led doctor Søren Helbo to find a way to limit the infection between patients in the waiting area:

“We always focus on limiting the migration of bacteria and viruses from patient to patient, while they wait for their examinations. At the same time, the solution should not be a nuisance for patients, therefore arose the idea of a UV lamp in the ceiling of our waiting area”, says Søren.

Therefore, on each side of the waiting area at the Lung Clinic is now two UV lamps, which shine with a wavelength of 222 nanometres - which means that the light does not damage either skin or eyes, but effectively kills bacteria and viruses. 

Søren Helbo continues: “We have measured the presence of bacteria in both periods and found that there are significantly fewer bacteria when the lamp is switched on. We are now investigating whether this also applies to the bacteria that can cause pneumonia.”

Thanks to the Lung Department at Aarhus University Hospital for being a pioneer in adopting our lights, and for sharing their experience.
