Denmark provides healthcare with UV Robots
"Please leave the room, close the door and start a disinfection," says a Robot, before it started its sterilization. This autonomous machine annihilates microorganisms solely by the ultraviolet light beams. The demand for such robots and other UV sterilization devices has skyrocketed, especially after the Coronavirus pandemic. Hundreds of such robots are now shipped throughout the World. Italy is naturally showing a high demand, as they are in a desperate situation.
8 UV bulbs that emit UVC light, are mounted on the Robot produced in Denmark. This kills bacteria, viruses, mites, fungi and other microorganisms by damaging their RNA and DNA chains, so that they cannot reproduce/multiply. The UVC light is also hazardous to humans, so the direct exposure should be avoided. It takes only ten to twenty minutes to remove 99.9% of microbes. Afterwards, there is a burning smell, caused by the Ozone, thus the room should be ventilated.
"There are a lot of problematic organisms that give rise to infections," said a professor of clinical microbiology at the University of Southern Denmark, Dr. Hans Jørn Kolmos, who helped the Robot creation. "If you apply a proper dose of ultraviolet light in a proper period of time, then you can be pretty sure that you get rid of your organism…This type of disinfection can also be applied to epidemic situations, like the one we experience right now, with coronavirus disease."
The robot is created in collaboration between the Odense University Hospital and Blue Ocean Robotics company, and launched in Q1 2019. The best method for removal of hospital-acquired infections or HAI, comes at a cost of 67,000 USD. However, one cannot put a price on life.
Although the Robots are not yet tested on COVID-19, there is a high confidence that it works on it as well:
"Coronavirus is very similar to other viruses like MERS and SARS. And we know that they are being killed by UV-C light," CEO Mr.Nielsen said, with which Dr. Lena Ciric at the London University College, faculty of molecular biology, agrees: “Disinfection robots are no silver bullet. However, these Robots provide an extra line of defense. We're in the run up to having a lot of coronavirus patients in the various hospitals. I think it's wise to be on top of the cleaning regimes… from an infection control point of view. "
Ultraviolet light has been employed for ages for air and water sterilization, and is commonly used in laboratories and hospitals. The novelty is mounting the lamps on intelligent robots.
Countless studies demonstrated the effectiveness of UV light at fighting the superbugs, such as Ebola. More than 500 hospitals in the US already have such a machine, and the numbers are growing in China as well. The Robots are employed in airports and by the large companies, and it is a matter of time when every one of us will see it in person.
