Manifold assembly for respiratory interface device

A manifold assembly for a patient interface device, the manifold assembly comprising:

• a manifold body including an elastic portion;
• a rotational coupling including a rigid conduit, wherein the rigid conduit is rotatably coupled to the manifold body elastic portion, wherein the rotational coupling and the elastic portion form a motion decoupling assembly, and wherein the motion decoupling assembly decouples the remaining portions of the manifold body from external forces applied to the rigid conduit;
• wherein the manifold body is elongated and defines a generally enclosed space, the manifold body includes an upper wall;
• wherein the elastic portion is disposed on the upper wall;
• wherein the manifold body further includes a first opening and a second opening;
• wherein the first opening is disposed on the elastic portion of the upper wall;
• wherein the rigid conduit includes a substantially circular cross-section;
• wherein the rigid conduit is rotatably coupled to the first opening;
• a stand-off device;
• wherein the manifold body includes a lower wall, an inner surface and a collar;
• wherein the collar includes an, inner, second end disposed within the manifold body enclosed space;
• wherein the manifold body lower wall and collar second end are part of the manifold body inner surface;
• wherein the stand-off device is disposed on the manifold body inner surface adjacent the first opening;
• and
• wherein the manifold body stand-off device includes a number of intermittent protrusions extending from one of the manifold body lower wall or collar second end.
