The coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has infected millions and killed hundreds of thousands of people worldwide as of May 2020. Healthcare providers are at increased risks of infection when caring for patients with COVID-19. The mechanism of transmission of SARS-CoV-2 is still not fully understood. However, there is growing evidence for airborne spread, in addition to direct droplet and indirect contact. Here, we report on the design, construction, and testing of the BADGER (Box for Aerosol and Droplet Guarding and Evacuation in Respiratory Infection), an affordable, scalable device that contains droplets and aerosol particles. A semi-sealed environment is created inside the BADGER, which maintains at least twelve-air changes per hour using in-wall vacuum suction, and multiple hand-ports enable healthcare providers to perform essential tasks on a patient’s airway and head. Overall, the BADGER has the potential to contain large droplets and small airborne particles as demonstrated by simulated qualitative and quantitative assessments to provide an additional layer of protection for healthcare providers treating COVID-19 patients.
