Abstract:
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 portions that contact opposing sides of the user's nose. Each portion of the mask seal includes supports that help maintain the mask seal's shape. Two covers can be supported relative to the mask assembly and adjacent a respective portion of the mask seal. The covers limit expansion of the portions of the mask seal in response to pressurized air within the mask seal. The supports can transfer load from the mask seal to the covers. An interface system can include multiple size mask seals, which can be designed with consideration of ethnic variations in nose size and/or shape.
