Patient interface device
A patient interface device that includes a support member sized and configured to span at least a portion of a patient's face while remaining below the patient's eyes responsive to the patient interface device being donned by such a patient and a sealing assembly operatively coupled to the support member such that the support member is moveable relative to the support member. The support member defines a gas carrying conduit adapted to carry a flow of gas to the sealing assembly. The support member is a single-piece unitary member and includes a conduit coupling portion adapted to be coupled to a patient circuit.
1. A patient interface device, comprising:
a support member sized and configured to span at least a portion of a patient's face while remaining below the patient's eyes responsive to the patient interface device being donned by such a patient, the support member being a single-piece unitary member and having a coupling portion configured to continuously span from a first side of a patient's face on a first side of the patient's nose to a second, opposite side of the patient's face on a second, opposite side of the patient's nose responsive to the patient interface device being donned by such a patient;
a sealing assembly operatively coupled to the support member at the coupling portion in a manner wherein the sealing assembly is rotatable relative to the support member about a longitudinal axis of the coupling portion and slideable relative to the support member along the longitudinal axis of the coupling portion while remaining in fluid communication with an interior of the support member, wherein the support member defines a gas carrying conduit adapted to carry a flow of gas to the sealing assembly; and
a pair of patient contacting members, each contacting member adjustably coupled to the support member at a location on the support member positioned to overlie a respective zygomatic bone of the patient when the patient interface device is donned by the patient,
wherein each contacting member of the pair of contacting members comprises a pad support adjustably coupled to the support member and a pad attached to the pad support opposite the support member, and
wherein the pad is structured to engage the respective zygomatic bone of the patient when the patient interface device is donned by the patient.
2. The interface device of claim 1 , wherein the sealing assembly includes a pair of nasal prongs, wherein each prong is structured to insert at least partially into a nostril of such a patient.
3. The interface device of claim 1 , wherein the pair of patient contacting members include a headgear attachment portion.
4. The interface device of claim 3 , further comprising a headgear assembly operatively coupled to the headgear attachment portion.
5. The interface device of claim 4 , wherein the headgear assembly is rotateably attached to the headgear attachment portion.
6. The interface device of claim 1 , further comprising an exhaust assembly disposed on the support member.
7. The interface device of claim 1 , wherein the support member is adapted to span a patient's face such that the longitudinal axis is generally parallel to an axis defined through such a patient's eyes.
8. The interface device of claim 1 , wherein the pad of each contacting member is detachably attached to the corresponding pad support.
9. The interface device of claim 1 , wherein the pad of each contacting member is permanently attached to the corresponding pad support.
