Abstract：
OBJECTIVE: To create an aerosol containment mask (ACM) that contains aerosols during common otolaryngologic endoscopic procedures while protecting patients from environmental aerosols.
METHODS: Bench testing.
METHODS: Mannequin testing.
METHODS: The mask was designed in SolidWorks and 3-dimensional printed. Mannequins were fitted with a nebulizer to generate aerosols. Commercial particle counters were used to measure mask performance.
RESULTS: The ACM has 2 ports on either side for instruments and endoscopes, a port for a filter, and a port that can evacuate aerosols contained within the mask via a standard suction pump. The mask contained aerosols on a mannequin with and without facial hair when the suction was set to 18.5 L/min. Other types of masks demonstrated substantial aerosol leakage under similar conditions. In a subsequent experiment, the ACM contained aerosols generated by a nebulizer up to the saturation of the particle detector without measurable leakage with or without suction.
CONCLUSIONS: The ACM will accommodate rigid and flexible endoscopes plus instruments and prevent leakage of patient-generated aerosols, thus avoiding contamination of the room and protecting health care workers from airborne contagions.

摘要：
目的：在耳鼻喉科普通内镜手术中制造一种包含气溶胶的气溶胶防护面罩（ACM），同时保护患者免受环境气溶胶的影响。
方法：台架试验。
方法：人体模型测试。
方法：该掩模是在SolidWorks中设计的，并进行了3维打印。人体模型装有雾化器以产生气溶胶。商业颗粒计数器用于测量掩模性能。
结果：ACM两侧有2个端口，用于仪器和内窥镜，过滤器的端口，以及可以通过标准抽吸泵排出包含在面罩内的气溶胶的端口。当抽吸设定为18.5L/min时,面罩在具有和不具有面部毛发的人体模型上含有气溶胶。其他类型的面罩在类似条件下显示出大量的气溶胶泄漏。在随后的实验中，ACM包含由雾化器产生的气溶胶,直到粒子检测器的饱和,在有或没有抽吸的情况下没有可测量的泄漏。
结论：ACM将容纳刚性和柔性内窥镜以及器械，并防止患者产生的气溶胶泄漏，从而避免房间受到污染，并保护医护人员免受空气传染。
