NUS scientists create foldable tent device to reduce virus exposure to medical staff treating Covid-19 patients

SINGAPORE - To further protect healthcare workers from Covid-19, researchers from the National University of Singapore have invented a foldable tent-like device that acts as a physical shield against the virus while they perform medical procedures that generate droplets and aerosols.

Negative pressure within the tent is created when connected to the hospital's central vacuum system or a battery-operated filtration system using a HEPA filter, to reduce leakage of exhaled aerosols or droplets from the patient. Besides cutting the risk of infection associated with aerosol generating procedures such as suctioning, intubation and extubation, the device also reduces contamination of the surroundings, which can also be a source of transmission.

Dart was designed in collaboration with doctors from the National University Hospital , and was two months in the making.
