The proposed COVER system utilizes a transparent tent-like hood that covers the head and torso of the patient and is connected to a suction-generating system designed to draw in air from both inside and surrounding the device across HEPA filters to remove 99.7% of all particles greater than 0.3um. For comparison, current guidelines recommend healthcare workers utilize N95 masks for high-risk procedures, and these masks only filter 95% of particles. The negative pressure chamber uses fans or a vacuum in an enclosed PVC structure to create a negative flow field. The fans or vacuum pull all air from inside the chamber through the HEPA filters before returning to the room environment. The HEPA filters prevent the infectious aerosolized particles from exiting the chamber, providing a barrier between contagious patients and the healthcare professionals and others outside the chamber.
