Accordingly, the initiative of creating a disinfectant system came in early February when Vietnam detected the very first infected cases and its completed version was launched one month later.

Vietnamese researchers have created mobile disinfection chambers to serve people working in areas affected by Covid-19. The body sterilization chamber using ion salt water.

The National Institute of Occupational and Environmental Health and the Hanoi University of Science and Technology have fabricated them for disinfecting people who directly treat or work with patients with Covid-19, the pneumonia caused by the new coronavirus.

The system consists of two chambers. One sprays electrolyzed water in the form of droplets and the other directs heat and ozone onto the body of the person. Produced by electrolyzing ordinary tap water containing dissolved sodium chloride, it can even clean the respiratory system.

After successful pilot period, three mobile disinfection chambers, which is the creation of HCM City University of Technology in collaboration with the Centre of Science and Technology Development for Youth, will be initially set up at the HCM City Youth Cultural House in District 1, HCM City Traditional Medicine Institute in Phu Nhuan district, and the Saigon Union of Trading Co-operatives (Saigon Co.op) in District 1. The newly-launched disinfection chamber is expected to be installed in COVID-19-high-risk areas containing COVID-19 sufferers, or suspected individuals such as quarantine zones, hospitals, as well as public places like supermarkets, railway and bus stations, airports, offices, schools, and other crowded areas.

The system, according to Hai and the researching team, can disinfect up to 99.99 percent of the virus, which has the size of one-900th of the width of a human hair, that might have still last on surfaces, either the clothes, shoes, or bags.

The main component of wet chamber is a 360-degree fog mist sprayer, combined with an infrared sensor installed inside the chamber that automatically activates the disinfection spraying process once a person steps in.

The system consists of two chambers, both measure one meter wide, two meters tall. One sprays electrolyzed water in the form of droplets while the other directs heat and ozone onto the body of the person. Produced by electrolyzing ordinary tap water containing dissolved sodium chloride, it can even clean the respiratory system. (Photo: Vnexpress)

The dry chamber uses heat and ozone at permitted level to ensure safety for the disinfected person. It takes one 30 seconds to complete a round of disinfection in each chamber, which measures one meter wide and two meters tall and is movable.

The entire system is designed and manufactured using Vietnamese techniques and products. The institute and the university have yet to come up with a production cost for the system, but it is estimated that the system can disinfect up to 1,000 people per day.

The cabin works automatically with green light turning on once a person stepping into and undergoes a round of disinfection period within 30 seconds (15 seconds in each chamber). The mobile cabin can serve as many as 1,000 person per day. (Photo: Vnexpress)

The system, according to the research team, can get rid of 99.99 percent of the new coronavirus, which is 1/900th the size of a human hair and clings to the surfaces of clothes, shoes bags and others. Its main component is a 360-degree fog mist sprayer using anolyte solution which is a powerful disinfectant against bacteria and viruses. The antiseptic solution of salt ions can help avoid skin irritation and sterilize the user’s nose and throat during inhalation without causing breathing difficulty. (Photo: Vnexpress)

The dry chamber uses heat and ozone at permitted level to ensure safety for the disinfected person. The team purposedly designs the chamber as a module so it can be easily installed, uninstalled and transported. Around 100 chambers could be manufactured a week to meet the needs in the city and southern provinces. (Photo: Vnexpress)

At the launching event on March 18, many people took turn to try the chamber. In Vietnam, the Ministry of Health confirmed more 9 new infections on 19 March middle night, all of them return home from overseas, raising the total number of infections to 85, 16 among recovered and discharged.

The whole-body disinfection chamber will partly address the need for screening and prevention of infection in crowded areas, especially at medical examination and treatment establishments, enterprises, schools and commercial centers. ., contributing to the prevention of disease spread.
