Abstract:
1. A patient interface assembly adapted to be coupled to a patient circuit, the patient interface assembly comprising: a first conduit having a first end, a central portion, and a second end, wherein the first conduit is configured and arranged such that (a) the first end of the first conduit is disposed proximate to a top of a head of a user responsive to the patient interface assembly being donned by the user, (b) the second end of the first conduit is disposed proximate to an airway of such a user responsive to the patient interface assembly being donned by the user, and (c) the central portion of the first conduit extends along a first side of a face of the user and is disposed between an eye and an ear of such of the user on the first side of the face responsive to the patient interface assembly being donned by the user; a second conduit having a first end, a central portion, and a second end wherein the second conduit is configured and arranged such that (a) the first end of the second conduit is disposed proximate to a top of a head of a user responsive to the patient interface assembly being donned by the user, (b) the second end of the second conduit is disposed proximate to an airway of such the user responsive to the patient interface assembly being donned by the user, and (c) the central portion of the second conduit extends along a second side of a face of the user opposite the first side and is disposed between an eye and an ear of such of the user on the second side of the face responsive to the patient interface assembly being donned by the user; a unitary attachment member operatively coupled to the first conduit and the second conduit, the unitary attachment member including a head strap member integrally attached to a chin support member, the head strap member being adapted to extend over the top of the head of the user responsive to the patient interface assembly being donned by the user, the chin support member having a first portion adapted to be disposed under and contact a mandible of the user responsive to the patient interface assembly being donned by the user, a second portion extending from the first portion and being adapted to be disposed on and contact a portion of a face of the user in between a nose and upper lip of the user responsive to the patient interface assembly being donned by the user, and an opening provided in between the first portion and the second portion; and a patient interface comprising a nasal interface structured to deliver a breathing gas to the user only through the nose of the user operatively coupled to the second end of the first conduit and the second end of the second conduit, wherein the first end of the first conduit and the first end of the second conduit are operatively coupled to the patient circuit, and wherein the opening is structured to receive a mouth of the user in a manner wherein the mouth is exposed to the ambient environment responsive to the patient interface assembly being donned by the user and while the breathing gas is being delivered to the user through the nasal interface.
