Abstract

An improved airflow delivery system wherein a primary conduit extends from a source of a stream of breathable gas to a patient or wearer. The primary conduit is rotatably connected to a manifold positioned on the top of the wearer's head. The manifold distributes the stream of breathable gas through at least two secondary conduits extending on generally opposite sides of the wearer's head to an airflow entrance structure for directing airflow into the nostrils of a wearer. This airflow entrance structure is a nasal mask or alternatively a nasal puff assembly. The secondary conduits are preferably secured to or integrally formed with straps connecting the airflow entrance structure to the manifold and used for securing the device to a user's head.
