Varanasi: An Ultraviolet Germicidal Irradiation (UVGI) system developed at the Malaviya Centre for Innovation, Incubation and Entrepreneurship (MCIIE) of IIT-BHU has been installed in the COVID lab of the BHU hospital for sanitization.
“Realizing the urgent need to develop low-cost, multi-purpose instruments for effective sanitization amid the coronavirus pandedmic, the MCIIE came up with innovative ready-to-use UVC-based products,” said the coordinator Prof PK Mishra. The centre has developed a wide range of UVC systems, he said adding, “Our advanced systems assure the elimination of biological contaminants such as viruses, bacteria, spores and allergens by effectively treating moving air with UVC radiation”. As per latest research, UVC light-based sterilizer can kill a range of microorganisms such as viruses (including SARS syndrome coronavirus and nipah virus) and bacteria in a short period. Mishra said that the system has a series of UV lamps (depending on size of place of installation), each having a capacity of 22 watts.
According to him, any virus can be deactivated up to 99% by the UVGI dose of 2400 microwatt sec/cm square. However, this system can produce UVGI dose of more than 2400 microwatt sec/cm square to ensure complete inactivation of coronavirus. This system also works on auto timer, and its visual red/green indicator ensures safety of the user against the UV dose.
The system can be used in hospitals, operation theatres, ICU and IVF labs, microbiological labs, special wards, dental facilities, laboratories, pharmaceutical units, patient care wards.
