Abstract
A cushion support assembly for a respiratory interface device cushion is provided. The cushion support assembly includes a cushion support assembly ribbon-like body with an inner side, an outer side and a wide facial side. The cushion support assembly body facial side includes a support surface, the support surface is structured to support the respiratory interface device cushion engagement portion in a generally planar configuration. The cushion support assembly body facial side support surface is generally planar relative to the user's respiratory interface device contour radial aspect.
Claims17
A cushion support assembly for a respiratory interface device cushion, the respiratory interface device cushion including a resilient body, the respiratory interface device cushion body including an engagement portion structured to engage a user's face, the user's face including a respiratory interface device contour, the user's respiratory interface device contour is a shaped loop including an axial aspect and a radial aspect, the respiratory interface device including a faceplate with a peripheral contour, the respiratory interface device cushion including a resilient body, the cushion support assembly comprising:
- a cushion support assembly ribbon-like body including an inner side, an outer side and a wide facial side, wherein the cushion support assembly body facial side includes a support surface, the support surface structured to support the respiratory interface device cushion engagement portion in a generally planar configuration, and wherein the cushion support assembly body facial side support surface is generally planar relative to the user's respiratory interface device contour radial aspect.
A respiratory interface device structured to engage a user's face, the user's face including a respiratory interface device contour, the user's respiratory interface device contour is a shaped loop including an axial aspect and a radial aspect, comprising:
- a faceplate including a body with a with a peripheral contour;
- a respiratory interface device cushion including a resilient body, the respiratory interface device cushion body including an engagement portion structured to engage a user's face;
- a cushion support assembly including a cushion support assembly ribbon-like body, wherein the cushion support assembly ribbon-like body includes an inner side and a facial side, wherein the cushion support assembly body facial side includes a support surface, wherein the support surface is structured to support the respiratory interface device cushion engagement portion, wherein the cushion support assembly body facial side support surface is generally planar relative to the user's respiratory interface device contour radial aspect, wherein the respiratory interface device cushion body is coupled to the cushion support assembly body, and wherein the respiratory interface device cushion body engagement portion extends substantially parallel to the cushion support assembly body facial side support surface.
A method of using a respiratory interface device structured to engage a user's face, the user's face including a respiratory interface device contour, wherein the user's respiratory interface device contour is a shaped loop including an axial aspect and a radial aspect, the respiratory interface device including a faceplate, a cushion, and a cushion support assembly, the faceplate including a body with a with a peripheral contour, the respiratory interface device cushion including a resilient body, the respiratory interface device cushion body including an engagement portion structured to engage a user's face, the cushion support assembly including a cushion support assembly ribbon-like body, the cushion support assembly ribbon-like body including an inner side and a facial side, the cushion support assembly body facial side including a support surface, the support surface structured to support the respiratory interface device cushion engagement portion, wherein the cushion support assembly body facial side support surface is generally planar relative to the user's respiratory interface device contour radial aspect, the method including:
- coupling the respiratory interface device cushion body to the cushion support assembly;
- positioning the respiratory interface device cushion body engagement portion to extend generally parallel to the adjacent cushion support assembly body facial side support surface;
- positioning the respiratory interface device over a user's respiratory orifice with the respiratory interface device cushion body engagement portion engaging the user's respiratory interface device contour.
