The aim of this study is to investigate the usability of conventional masks to prevent the transmission of coronavirus 2019 (COVID-19) and subsequently design the proposed concept of the mask to reduce leakage and increase efficiency. Acute respiratory syndrome COVID-19 is spreading around the world and can be transmitted from one person with COVID-19 to another through personal contact and breathing. Improper design of current masks can lead to virus transmission. One hundred fifteen users participated in the study using a simple random sampling method in which N95–FFP2 face mask and surgery face mask usability tests were chosen as the most widely used face masks in Iranian people with an online usability questionnaire. Data were analyzed by SPSS. The results showed that the usability of the N95–FFP2 face mask with a total average of 4.46 and a surgical mask with a total average of 3.35 cannot be considered acceptable. Anthropometric and formal changes in people's faces and improper design of the face masks used make it necessary to review the mask redesign measures to increase the prevention of pathogens. In this study, new parameters for face mask design are proposed. Thirty different types of jaws have been considered with the help of CorelDRAW software, along with ideas for optimal mask design with UVW mask concept to be accessed by manufacturers around the world.

面罩可用性和设计参数的研究：用于保护 COVID-19 的 UVW 面罩的概念设计


本研究的目的是调查传统口罩预防 2019 年冠状病毒 (COVID-19) 传播的可用性，并随后设计所提出的口罩概念，以减少泄漏并提高效率。急性呼吸系统综合症 COVID-19 正在世界各地传播，可以通过个人接触和呼吸从一个 COVID-19 感染者传播给另一个感染者。当前口罩设计不当可能导致病毒传播。 115名用户采用简单随机抽样方法参与了这项研究，其中通过在线可用性调查问卷，选择N95-FFP2口罩和手术口罩可用性测试作为伊朗人民最广泛使用的口罩。数据通过SPSS进行分析。结果显示，N95-FFP2口罩的总平均值为4.46，而外科口罩的总平均值为3.35，可用性不可接受。人们面部的人体测量和形式变化以及所用口罩的设计不当，使得有必要审查口罩重新设计措施，以加强对病原体的预防。在这项研究中，提出了面罩设计的新参数。在 CorelDRAW 软件的帮助下，我们考虑了 30 种不同类型的钳口，以及采用 UVW 掩模概念的最佳掩模设计想法，可供世界各地的制造商获取。
