患者接口
摘要：
在此披露一种用于正压呼吸疗法的接口，该接口包括面罩组件，该面罩组件具有面罩密封件和面罩壳体。该面罩组件低于用户鼻梁定位并且使该鼻梁外露。该面罩密封件包括位于鼻区的对应第一侧和第二侧上的接触该用户鼻部的相反侧的第一部分和第二部分。该第一部分和该第二部分各自包括帮助维持该面罩密封件的形状的多个支撑件。一对覆盖物能够相对于该面罩组件并且邻近该面罩密封件的该第一部分和该第二部分中的对应一者被支撑。这些覆盖物限制该面罩密封件的该第一部分和该第二部分响应于该面罩密封件内的加压空气而扩展。该第一部分和该第二部分的这些支撑件能够将负载从该面罩密封件转移到这些覆盖物。
摘要（英）：

An interface for positive pressure respiratory therapy includes a mask assembly having a mask seal and a mask shell. The mask assembly is positioned lower than and exposes a bridge of the user's nose. The mask seal includes first and second portions on respective first and second sides of a nasal region that contact opposing sides of the user's nose. The first and second portions each include supports that help maintain a shape of the mask seal. A pair of covers can be supported relative to the mask assembly and adjacent a respective one of the first and second portions of the mask seal. The covers limit expansion of the first and second portions of the mask seal in response to pressurized air within the mask seal. The supports of the first and second portions can transfer load from the mask seal to the covers.
