截至2020年12月，由严重急性呼吸系统综合征冠状病毒2型（SARS-CoV-2）引起的2019冠状病毒病（COVID-19）大流行已感染全球数百万人，并导致超过170万人死亡。医疗服务提供者在护理COVID-19患者时，感染的风险增加。SARS-CoV-2的传播机制除了直接飞沫和间接接触作为主要传播途径外，还开始出现空气传播。在这里，我们报告了BADGER（呼吸道感染气溶胶和液滴防护和疏散盒）的设计，构造和测试，这是一种经济实惠的可扩展设备，包含液滴和气溶胶颗粒，从而最大限度地降低了医疗服务提供者的感染风险。在BADGER内部创建半密封环境，将其放置在患者头部上方，并使用壁内真空抽吸保持每小时至少12次换气。多个手持端口使医疗保健提供者能够在患者的气道和头部执行基本任务。总体而言，模拟定性和定量评估表明，BADGER有可能包含大液滴和空气中的小颗粒，为治疗COVID-19和未来呼吸道传染病的医疗保健提供者提供额外的保护。
The coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has infected millions and killed more than 1.7 million people worldwide as of December 2020. Healthcare providers are at increased risk of infection when caring for patients with COVID-19. The mechanism of transmission of SARS-CoV-2 is beginning to emerge as airborne spread in addition to direct droplet and indirect contact as main routes of transmission. 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, thus minimizing the risk of infection to healthcare providers. A semi-sealed environment is created inside the BADGER, which is placed over the head of the patient and maintains at least 12-air changes per hour using in-wall vacuum suction. 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 and future respiratory contagions.
