A nasal cannula assembly can include a cannula, an optional manifold, a gas supply tube, and a securement mechanism. Securement mechanisms can include headgear straps, cheek pads, or an adhesive nose strip. A nasal cannula assembly can also include a lanyard, lanyard clip, and/or lanyard connector to help support the weight of a main gas delivery conduit. ## Claims ### Claim 1 A nasal cannula assembly for administering a breathable gas to a user, the nasal cannula assembly comprising: a nasal cannula comprising: a first section comprising a first material, and a second section comprising a second material; a manifold with a manifold connection comprising a rigid material relative to the first material, wherein the manifold connection is substantially C or U shaped; wherein the first section is relatively softer than the second section, wherein the first section and second section are commensurately or complimentarily shaped or configured to communally receive the substantially C or U shaped manifold connection for delivery of a gas to the user, wherein the nasal cannula comprises a body defining an open cavity configured to receive the substantially C or U shaped manifold connection for delivery of the gas to the user, the first section defining at least a portion of the open cavity, wherein the substantially C or U shaped manifold connection has a concave surface forming the C or U shape and an opposite surface, wherein the body covers the concave surface and the opposite surface when the substantially C or U shaped manifold connection is received within the body; a rear portion of said body being, in-use, substantially adjacent to the user's septum region, the rear portion being substantially compliant or deformable in response to a pressure applied by the user to said rear portion, wherein the rear portion defines at least a part of a rear wall of the open cavity, formed as a pillow section to be substantially adjacent to the user's septum region in-use, the rear portion being one or more of: a substantially thinned wall section of the body, or a substantially elasticised wall section of the body. ### Claim 2 (depends on 1) The nasal cannula assembly as claimed in claim 1, where the second material is different from the first material. ### Claim 3 (depends on 1) The nasal cannula assembly as claimed in claim 1, wherein the first section and the second section are assembled to each other through the use of one or more fastening systems. ### Claim 4 (depends on 1) The nasal cannula assembly as claimed in claim 1, wherein the second section provides for a structural or support or shape-defining, component part, of the nasal cannula. ### Claim 5 (depends on 4) The nasal cannula assembly as claimed in claim 4, wherein the configuration or shape of the first section is at least in part defined by parts or portions of the second section. ### Claim 6 (depends on 1) The nasal cannula assembly as claimed in claim 1, wherein the first section encapsulates at least a part of the second section. ### Claim 7 (depends on 1) The nasal cannula assembly as claimed in claim 1, wherein the second section is at least in part over-moulded by the first section. ### Claim 8 (depends on 1) The nasal cannula assembly as claimed in claim 1, wherein the second section is adapted to receive the substantially C or U shaped manifold connection. ### Claim 9 (depends on 1) The nasal cannula assembly as claimed in claim 1, wherein the first section comprises one or more surface relief portions, the surface relief portion(s) of the first section engageable with an associated one or more commensurately or complimentarily shaped or configured surface relief portions of the second section. ### Claim 10 (depends on 1) The nasal cannula assembly as claimed in claim 1, wherein the second section extends around the first section. ### Claim 11 (depends on 1) The nasal cannula assembly as claimed in claim 1, wherein the nasal cannula includes a pair of side arms extending outwardly from the body. ### Claim 12 (depends on 11) The nasal cannula assembly as claimed in claim 11, wherein located substantially toward each end of the side arms is a connection system for connecting a headgear. ### Claim 13 (depends on 1) The nasal cannula assembly as claimed in claim 1, wherein a concave side of the C or U shape, in use, faces the rear portion of the body, wherein the rear portion of the body is adapted to be substantially adjacent to the user's septum region in use. ### Claim 14 (depends on 1) The nasal cannula assembly as claimed in claim 1, wherein the open cavity is in fluid communication with one or a pair of nasal prongs. ### Claim 15 (depends on 1) The nasal cannula assembly as claimed in claim 1, wherein the manifold is a side-entry manifold. ### Claim 16 A nasal cannula assembly for administering a breathable gas to a user, the nasal cannula assembly comprising: a first section formed from a first material; a second section formed from a second material; a manifold with a manifold connection comprised of a rigid material relative to the first material; wherein the first section is relatively softer than the second section, wherein the first section and the second section comprises a body defining an open cavity engageable by the manifold connection, the first section defining at least in part said open cavity; a rear portion of said body being, in-use, substantially adjacent to the user's septum region, the rear portion being substantially compliant or deformable in response to a pressure applied by the user to said rear portion, wherein the rear portion defines at least a part of a rear wall of the open cavity, formed as a pillow section to be substantially adjacent to the user's septum region in-use, the rear portion being one or more of: a substantially thinned wall section of the body, or a substantially elasticised wall section of the body; wherein the manifold connection is substantially C or U shaped and a concave rear side of the C or U shape, in use, faces the rear portion, wherein the body covers the concave rear side of the C or U shape and a front side of the manifold connection when the manifold connection is received within the body. ### Claim 17 A nasal cannula assembly for administering a breathable gas to a user, the nasal cannula assembly comprising: a nasal cannula comprising: a first section comprising a first material, and a second section comprising a second material; a manifold with a manifold connection comprising a rigid material relative to the first material, wherein the manifold connection is substantially C or U shaped; wherein the nasal cannula comprises a body defining an open cavity configured to receive the manifold connection for delivery of the gas to the user, the first section defining at least a portion of the open cavity, wherein the manifold connection is substantially C or U shaped and a concave rear side of the C or U shape, in use, faces the rear portion, wherein the body covers the manifold connection from the concave rear side to a front side; wherein a hollowed region is bound by the substantially C or U shaped manifold connection and a rear portion of the body when the substantially C or U shaped manifold connection is received within the body, the hollowed region substantially adjacent to the user's septum region in-use, the rear portion configured to deform the hollowed region to improve comfort or reduce the application of pressure points by the substantially C or U shaped manifold connection.
