Infectious disease experts have long known the way to keep a deadly virus from spreading across hospital wards is to confine contagious patients to negative-pressure rooms.

Now researchers at the USC Caruso Department of Otolaryngology – Head and Neck Surgery are taking that idea to the next level, developing a procedure face mask that lets them safely scope their patients during the COVID-19 pandemic.

The mask goes on the patient, not the doctor.

Negative air pressure inside the mask prevents viral contamination of the clinic space, and built-in sensors and air-flow balance control allows the use of supplementary oxygen, meaning even very sick patients can undergo endoscopy.
