Patient intreface assembly supported under the mandible
View Patent ↗A patient interface assembly that includes a substantially rigid support and a patient interface device coupled to a first end of the support. A first arm is coupled to a first side of the support and a second arm is coupled to a second side of the support. A cross member spans between the first arm and the second arm such that the cross member is disposed under a patient's mandible when the patient interface assembly is worn by a user. An addition, a conduit is coupled to a second end of the support.
1. A patient interface assembly comprising:
a substantially rigid support having a first end and a second end opposite the first end;
a patient interface device coupled to the first end of the support;
a first arm coupled to a first side of the support;
a second arm coupled to a second side of the support;
a generally U-shaped cross member having a first end coupled to the first arm and a second end coupled to the second arm and spanning between the first arm and the second arm, the generally U-shaped cross member having a central portion located midway between the first and second ends of the generally U-shaped cross member, wherein a first side of the second end of the substantially rigid support is coupled to the central portion of the U-shaped cross member such that a longitudinal axis of the substantially rigid support is aligned with a centerline of the patient responsive to the patient interface assembly being worn by the patient, wherein a coupling port having an exterior side and an interior side opposite the exterior side is provided at a second side of the second end of the substantially rigid support opposite the first side of the second end of the substantially rigid support, wherein the exterior side of the coupling port is structured to be coupled to a patient circuit; and
a flexible conduit provided within the substantially rigid support having a first end coupled to the interior side of the coupling port and a second end coupled to the patient interface device, wherein the flexible conduit extends within the substantially rigid support from the first end of the substantially rigid support to the second end of the substantially rigid support and from the interior side of the coupling port to the patient interface device.
2. The patient interface assembly of claim 1 , further comprising a headgear assembly operatively coupled to the U-shaped cross member and adapted to overlie a portion of a patient's head responsive to the patient interface assembly being donned by such a patient.
3. The patient interface assembly of claim 1 , wherein the cross member is flexible, rigid, or semi-rigid.
4. The patient interface assembly of claim 1 , wherein the patient interface device is a nares element or a nasal cushion.
5. The patient interface assembly of claim 1 , wherein the patient interface device is selectively detachable from the support.
6. The patient interface assembly of claim 1 , further comprising a headgear attachment element disposed on the first arm and the second arm.
7. The patient interface assembly of claim 1 , further comprising an exhaust assembly associated with the support.
