Abstract
A respiratory interface device is provided. The respiratory interface device includes at least one elongated support member structured to contact a user. The support member has at least one conduit portion and at least one porous portion. The conduit portion is structured to allow the passage of gas therethrough. The conduit portion is structured to be in fluid communication with a pressure generating system and with the porous portion. The porous portion is structured to allow for axial passage of gas therethrough and for radial exhaust of gas therefrom.
Claims20
A support assembly for a respiratory interface device comprising:
- an elongated support member structured to contact a user, the support member having a conduit portion and at least one porous portion, wherein the conduit portion is structured to allow the passage of gas therethrough and adapted to be in fluid communication with a pressure generating system, and wherein the conduit portion is in fluid communication with the porous portion, wherein the porous portion is structured to allow for passage of gas therethrough and for exhaust of gas therefrom to an ambient environment, and wherein the porous portion is structured to be in fluid communication with a mask.
A support assembly for a respiratory interface device, the respiratory interface device including a mask having an opening, the support assembly comprising:
- an elongated support member structured to contact a user and including a porous portion, wherein the porous portion is structured to allow for axial passage of gas therethrough and radial exhaust of gas therefrom to an ambient environment;
- and wherein the porous portion being in fluid communication with the mask opening.
A method of using a respiratory interface device, the respiratory interface device including a mask having a mask opening therethrough and a pressure generating system structured to generate a flow gas at an elevated pressure, the support assembly including an elongated support member structured to contact a user, the at least one support member having at least one conduit portion and a porous portion, the conduit portion is structured to allow the passage of gas therethrough, the conduit portion being in fluid communication with the pressure generating system and being in fluid communication with the porous portion, the porous portion is structured to allow for axial passage of gas therethrough and radial exhaust of gas therefrom to an ambient environment, and the porous portion being in fluid communication with the mask opening, the method comprising:
- positioning the mask over at least one of the user's nose or mouth;
- generating a flow of pressurized gas;
- communicating the pressurized gas via support assembly to the mask;
- and
- exhausting a portion of the pressurized gas radially through the porous portion.
