在 COVID-19 大流行等病毒爆发期间，普通民众使用口罩虽然有时引起争议，但已有效减缓病毒的传播。口罩减轻传播的程度很大程度上取决于口罩适合每个人的程度。简单的布口罩在面部的贴合度，以及由此产生的周边泄漏和口罩功效，预计将高度依赖于口罩的类型和面部拓扑。然而，迄今为止，这种影响尚未得到充分检查和量化。在这里，我们提出了一个框架来研究不同口罩设计的功效，该框架基于将口罩部署到各种面部的准静态机械模型。为了说明所提出的框架的功能，我们在由 3D 可变形面部模型生成的大量虚拟受试者群体上探索了一个简单的矩形布掩模。研究了体重、年龄、性别和身高对面罩贴合度的影响。疾病控制与预防中心 (CDC) 推荐的自制布口罩设计被用作比较的基础，结果发现这并不是对所有受试者最有效的设计。我们强调设计口罩时考虑到广泛不同的面孔人群的重要性。基于空气动力学原理的指标被用来确定瘦弱、女性化和年轻的面孔可以从小于疾病预防控制中心建议的尺寸的口罩中受益。除了掩模尺寸之外，还对掩模的侧边折入或打褶作为设计参数进行了研究，发现有可能导致更大的局部间隙开口。
The use of face masks by the general population during viral outbreaks such as the COVID-19 pandemic, although at times controversial, has been effective in slowing down the spread of the virus. The extent to which face masks mitigate the transmission is highly dependent on how well the mask fits each individual. The fit of simple cloth masks on the face, as well as the resulting perimeter leakage and face mask efficacy, are expected to be highly dependent on the type of mask and facial topology. However, this effect has, to date, not been adequately examined and quantified. Here, we propose a framework to study the efficacy of different mask designs based on a quasi-static mechanical model of the deployment of face masks onto a wide range of faces. To illustrate the capabilities of the proposed framework, we explore a simple rectangular cloth mask on a large virtual population of subjects generated from a 3D morphable face model. The effect of weight, age, gender, and height on the mask fit is studied. The Centers for Disease Control and Prevention (CDC) recommended homemade cloth mask design was used as a basis for comparison and was found not to be the most effective design for all subjects. We highlight the importance of designing masks accounting for the widely varying population of faces. Metrics based on aerodynamic principles were used to determine that thin, feminine, and young faces were shown to benefit from mask sizes smaller than that recommended by the CDC. Besides mask size, side-edge tuck-in, or pleating, of the masks as a design parameter was also studied and found to have the potential to cause a larger localized gap opening.
