Health Desk- 08 Jan 2021: South Korean researchers say they have designed an inflatable “negative pressure” ward for isolating and treating patients with infectious diseases like COVID-19, after the pandemic exposed shortages of such beds around the world.
The rooms use a ventilation system that creates negative pressure to allow air to flow into the isolation room and be channelled out safely, helping prevent the spread of airborne pathogens.
They have become a vital tool for fighting the coronavirus pandemic, but many countries have struggled to create them quickly enough.
The mobile clinic modules designed by a research team at the Korea Advanced Institute of Science and Technology (KAIST) are large greenhouse-like inflatable tents, which the institute said cost a fifth of the price of building a conventional hospital ward.
Nam Tek-jin, an industrial design professor who led the KAIST team, says their tents, which are the size of a basketball court, can be installed and equipped in less than a day.
