Amidst the Covid-19 pandemic, people have been putting in effort to sanitise themselves and maintain good hygiene at all times. During difficult times like this, a portable full-body disinfection chamber was designed by the Institute of Occupational Health and Environment in Vietnam.
In collaboration with Hanoi University of Science and Technology, this chamber has been manufactured and is currently being piloted in medical examination and crowded areas.
As reported on Tips Make, the portable disinfection chamber only requires 15 to 20 seconds to disinfect a person’s body.
Designed in February 2020, this chamber was meant for easy transportation so that it can be placed at areas that expect crowds – where there is a higher risk of spreading pathogens.
It is said that this device is capable of disinfecting up to 1,000 people in a single day.
Apparently, the disinfection system was designed based on the application of ionised saline solution (Anolyte) in the form of a mist to spray onto the body for a quick sterilisation.
Associate Professor Dr Doan Ngoc Hai, the Director of Vietnam Academy of Science and Technology (VAST), explained that all disinfection solutions are prepared by the academy in order to ensure the safety of the solution when sprayed onto sensitive skin areas.
On the disinfection chamber, instructions are provided for people to follow, all for the intention of preventing the spread of Covid-19.
Initial results of the effectiveness of this design showed that over 90 percent of bacteria and viruses on body and clothes surfaces vanished after using the disinfection chamber. The effectiveness was proven via a microbiological test performed by the Department of Laboratory and Analysis (Institute of Occupational Health and Environment).
Currently, engineers are in the process of making new chambers to be placed at high-risk areas like the Central Tropical Hospital as well as the quarantine areas. Additionally, there are also plans to install these chambers at other places such as schools and commercial centres.
While this model of the portable chamber is being piloted in Hanoi at the moment, the Institute is also working on designing another chamber specifically to sterilise doctors’ clothes, calling it “clothes drying sterilisation chamber”.
