Chin pivot patient interface device
View Patent ↗A patient interface device that includes a body portion comprising a pair of arms and a chin support. A first end portion of each arm in the pair of arms is coupled to an opposite end of the chin support. The chin support is adapted to be disposed under the mandible responsive to the patient interface device being donned by a user. At least one headgear attachment element is provided on each arm in the pair of arms. A circuit portion is provided at a second end portion of each arm in the pair of arm. A patient interface portion is coupled to the circuit portion.
1. A patient interface device comprising:
(a) a body portion comprising:
(1) a pair of arms,
(2) a chin support, wherein a first end portion of each arm in the pair of arms is coupled to an opposite end of the chin support, and wherein the chin support is adapted to be disposed under the mandible of a user responsive to the patient interface device being donned by such a user,
(3) a pair of headgear attachments, and
(4) a circuit portion operatively coupled to a second end portion of each arm in the pair of arms, wherein each headgear attachment in the pair of headgear attachments is disposed on each arm in the pair of arms between the first end portion and the second end portion; and
(b) patient interface portion operatively coupled to the circuit portion.
2. The patient interface device of claim 1 , wherein the patient interface portion includes one of a pair of a nasal prongs, a nasal cushion, and a full face cushion.
3. The patient interface device of claim 1 , wherein the chin support comprises a flexible strap.
4. The patient interface device of claim 1 , wherein the chin support comprises one of a rigid member, a semi-rigid member, and a pad.
5. The patient interface device of claim 1 , wherein the patient interface portion is adjustably coupled to the circuit portion.
6. The patient interface device of claim 1 , further comprising an exhaust assembly associated with the patient interface portion, the circuit portion, or both.
7. The patient interface device of claim 1 , wherein the pair of arms are (a) integral with the circuit portion, or (b) selectively attachable to the circuit portion.
8. The patient interface device of claim 1 , wherein the circuit portion includes (a) a single gas flow conduit in fluid communication with the patient interface portion, or (b) a pair of gas flow conduits in fluid communication with the patient interface portion.
9. The patient interface device of claim 1 , further comprising an oral member adapted to (a) cover a mouth of such a user, or (b) seal an oral passage of such a user.
10. The patient interface device of claim 9 , wherein the oral member is (a) a strap extending between the pair of arms, or (b) a lip sealing assembly operatively coupled to the circuit portion or the pair of arms and adapted to be inserted into a mouth of such a user past such a user's lips.
11. The patient interface device of claim 1 , further comprising a mouthpiece coupled to the body portion.
12. The patient interface device of claim 11 , further comprising an oral path defined in the mouthpiece so as to communicate the circuit portion with the oral cavity responsive to the patient interface device being worn by such a user.
13. The patient interface device of claim 1 , further comprising a headgear operatively coupled to the pair of headgear attachment elements.
14. The patient interface device of claim 1 , wherein the patient interface is a nasal cushion including at least one groove defined in a wall portion of the nasal cushion.
