Abstract

To test the feasibility of replicating a face mask seal in vitro, we created 5 geometrically accurate reconstructions of the head and neck of an adult human subject using different materials. Three breathing patterns were simulated with each replica and an attached N95 mask. Quantitative fit testing on the subject and the replicas showed that none of the 5 isotropic materials used allowed duplication of the ex vivo mask seal for the specific mask-face combination studied.

摘要

为了测试在体外复制口罩密封的可行性，我们使用不同的材料创建了 5 个成人头部和颈部的几何精确重建。用每个复制品和一个附加的 N95 口罩模拟了 3 种呼吸模式。对受试者和复制品进行的定量贴合测试表明，在所研究的特定口罩-面部组合中，使用的 5 种各向同性材料均无法复制体外口罩密封。
