The face mask is a device to facilitate the delivery of gases from a breathing system to a patient by creating an airtight seal around the face. Of the many types of face masks available, the anatomical face mask is most commonly used for anaesthesia. With repeated usage, the seal of the anatomical face mask becomes flattened due to the loss of air in the cushion, leading to a poor fit on the patient's face. This results in air dilution during spontaneous respiration and inadequate gas exchange during controlled ventilation. A simple solution to restore this seal has been provided.
面罩是一种通过在面部周围形成气密密封来促进气体从呼吸系统输送到患者的装置。在众多可用的面罩类型中，解剖学面罩最常用于麻醉。随着反复使用，解剖学面罩的密封因垫子中的空气流失而变平，导致与患者面部贴合不佳。这会导致自主呼吸时空气稀释以及控制通气时气体交换不足。已经提供了一种恢复这种密封的简单解决方案。
