Tracheal intubation is one of the highest-risk moments for COVID-19 transmission to healthcare workers and other patients. The current strategy in Canadian hospitals to minimise the risk to healthcare workers during these procedures is to shield the workers from droplets and aerosols by having them wear Personal Protective Equipment (PPE). We believe that better containment and even elimination of the droplets and aerosols should be done at the source, i.e., at the patient. We are a team composed of engineering professors from Polytechnique Montreal and Ecole de Technologie Superieure, medical doctors from Hopital Maisonneuve-Rosemont, and plastic manufacturing specialists from the SME CYB Plastiques. We propose to develop three (3) different designs of aerosol containment enclosures to put around the patient during high risk procedures to shield the room from exposure. We will minimally adapt existing box designs and establish a Canadian production network to put them in our hospitals ASAP. We will develop a box with improved performance and better functionalities. We will develop a disposable box which can be mass-produced cheaply and rapidly. We will test in the lab and visualise the effectiveness of the different box designs to confine/eliminate aerosols with fluorescent particles, and perform clinical tests at the hospital of pre-approved prototypes. Finally, to maximise the adoption of these boxes in Canadian hospitals, we will disseminate the open-source design freely and communicate with medical practitioners to inform them about the availability of these boxes made in Montreal.

气管插管是将COVID-19传播给医护人员和其他患者的最高风险时刻之一。加拿大医院目前的策略是通过让医护人员佩戴个人防护装备（PPE）来保护他们免受飞沫和气溶胶的伤害，从而最大限度地降低医护人员在这些过程中的风险。我们认为，应该从源头，即患者，更好地遏制甚至消除液滴和气溶胶。
