Robots Being Used to Disinfect Hospital Rooms

Amid the coronavirus spread the interest in using robots to disinfect surfaces and rooms has increasedUVD Robots ApS has reached a distribution agreement with Sunay Healthcare Supply to deploy its disinfection robots in China. 

UVD Robots ApS was founded in 2016 with the objective of global commercialising robotic based UV Disinfection solutions for hospitals. UVD Robots philosophy is centred around integrating proven UV germicidal industrial solutions with new advanced robot technologies, while creating innovative products to help the healthcare industry in the eradication of harmful pathogens and superbugs found in the environment, such as infectious diseases, viruses, bacteria and other organic microorganisms. Thereby, producing a safer healthcare environment and improving the quality of care in hospitals and healthcare facilities around the world. Moreover, the robot is safe, reliable and corrects the human’s mistake. 

Su Yan, CEO of Sunay Healthcare Supply, has declared that with this agreement, more than 2,000 hospitals will now have the opportunity to ensure effective disinfection, protecting both their patients and healthcare workers. Furthermore, he added that UVD robot is superior compared to other technologies. 

UV disinfection has been clinically proven to remove bacteria during the last 40 years. It was mainly used to disinfect potable water and E. coli in wastewater treatment plants. Hospitals in Europe and America began to apply UV-C manual systems about 10 years ago. The first generation was a portable light used to disinfect operating theatres which increased sales. This system has some disadvantages. For instance, UV-C light is limited by factors such as the areas covered. Therefore, it is quite important to go through the whole room covering all angles. The light UV-C germicide effect is also limited by the distance. From the source: the intensity is guided by the inverse-square law. The higher the power level, the shorter the disinfection time. 

Unlike UV-C light, the robot automatically repositions itself near surfaces instead of needing someone to get inside and outside the room. There is not persistent radiation: The robot takes between 12 and 15 minutes disinfecting a small hospital room (one bed and bathroom). Once the lights are turned off, people can start getting inside the room. Once you’re in, you’ll smell “ozone”, but this wavelength does not produce ozone. Therefore, the smell comes from the burned particles in the air, i.e. skin and hair. 

Not only is the robot able to clean hospitals but also boat cabins or wider spacessuch as hotels, offices and airport security control areas. 

On the other hand, Akara Robotics has also develop a robot called the Robot Violet to fight the COVID-19 with disinfectant at hospitals. The robot uses UV technology and is clinically proven to completely kill the virus, bacteria and other harmful germs within a short period of time, which make it more effective than the usual cleaning methods. Dr. McGinn, his inventor, said “this system could reduce dependency on the use of chemical-based solutions, which may be effective but requires rooms to be vacated for several hours during sterilisation, making them impractical for many parts of the hospital. In addition, many pieces of high-tech equipment cannot be disinfected using “deep chemicals”, so Robot Violet is also effective in such circumstances. 

The company Blue Ocean Robotics has also sent hundreds of cleaning robots that were usually used to disinfect living rooms and aisles through UV in many hospitals in China. In the United States, the start-up Brain Corp, a company quite involved in new cleaning standards, has been in charge of providing software for cleaning robots used in companies such as Walmart. Michel Spruijtgeneral manager for Europe for Brain Corp, says that Brain Corp’s typical customers used to be malls and grocery stores, but now due to pandemic, warehouses, airports and hospitals are also getting in touch.
