The Research Institute of the McGill University Health Centre is conducting the first Canadian test of the UVD Robot that uses ultraviolet light to disinfect.
The institute moved to order the UVD Robot just as the COVID-19 pandemic was emerging in China and Europe to see if the technology could be useful to Canada.
The UVD Robot is currently being tested in other Quebec locations — notably the Centre hospitalier de l’Université de Montréal and long-term care homes.
“We are going to test its mobility, if it is able to go to our rooms, in all corners, if UV light touches all parts of the room, and in addition if the robot is able to enter the bathrooms (in private rooms) and completely disinfect them,” said Dr. Bruce Mazer, Interim Executive Director and Acting Chief Scientific Officer of the Research Institute.
The UVD Robot can also be used to disinfect an operating room. As part of the test, its effectiveness will also be tested on various objects, such as sheets, stretchers and even N95 masks.
While ultraviolet C rays are able to kill pathogens on surfaces and in the air, they can be dangerous to humans.
“The problem with UV light is that it is very effective in killing bacteria and viruses, but if you have too much UV, it can burn the skin and it can cause eye problems,” Mazer said. “But with this type of UV, if you close the door, even if there is a window, that doesn’t happen, so it is safe.”
Mazer noted that manual room-cleaning takes about an hour, while the robot could do that job in about 10 minutes. A human would be required to do other tasks like changing sheets, but ultimately a room could be ready for the next patient twice as fast.
“If we have a way of doing things with technology that is fast and efficient, we can save money, we can have rooms faster for other patients and we can avoid risks for our workers,” Mazer said.
