A newly developed disinfection trolley uses UV light which is harmful for virus such as COVID-19 and can clean up hospital spaces easily in short time
New Delhi: Proper and full disinfection is a must during the COVID-19 infection, something which is a primary concern for hospitals where patients are treated every day. Liquid disinfectants can only do so much and also is a time taking process.
To solve that very issue, the International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), an autonomous R&D Centre of the Union government’s Department of Science and Technology (DST), and University of Hyderabad (UoH) together with the help of Mekins Industries Ltd (MIL), have developed a UVC based disinfection trolley to fight against COVID-19 by rapid cleaning of hospital environment.
The UVC sterilisation trolly comprises of 6 UVC germicidal cylinders, which are orchestrated so that three sides are illuminated with two tubes confronting every heading. While these lights deal with purification on the walls, bed, and room air, the floor cleansing is finished by 2 littler UV lights situated at the base facing the floor. The hospital rooms get cleaned when the trolley is moved around in the room by an administrator in a protective suit and UV safe goggles. Overall, the administrator moving the UVC trolley framework with a normal speed of 5ft/min can cover a room of 400 sq ft inside 30 minutes for complete (>99%) sanitization.
The current framework is the first model and is promptly usable in hospitals and railroad coaches that are likewise being made arrangements for treatment of COVID-19 patients. Systems with smaller dimensions and further automation are in progress in view of rapid disinfection required in aircraft cabins. The UV-light cleansing framework must be worked in vacant rooms after the patient is released and without wellbeing faculty.
UV light in the scope of frequencies somewhere in the range of 200 and 300 nm is equipped for inactivating microorganisms, for example, microbes and viruses, consequently sanitizing both air and solid surfaces. Coronavirus is sensitive to UVC light, as in the case of other viruses and bacteria. The germicidal effects of UVC irradiation with a peak intensity at 254 nm results in cellular damage of the virus, thereby inhibiting cellular replication.
