US Patent 10118008 Manifold assembly for respiratory interface device

A respiratory interface device is provided. The respiratory interface device includes a manifold assembly including a manifold body and a rotational coupling. The manifold body includes an elastic portion. The rotational coupling includes a rigid conduit. The rigid conduit is rotatably coupled to the manifold body elastic portion. The rotational coupling and the elastic portion decouple the remaining portions of the manifold body from external forces applied to the rigid conduit.
