Abstract

A patient interface device includes a cushion defining a cavity therein, the cushion having a first side and an opposite second side. An aperture is formed in the second side and provides access to the cavity, the aperture having a periphery adapted to sealingly engage about the nostrils of a patient when the cushion is disposed on the face of a patient. The patient interface device further includes a pair of stabilizing members coupled to, and extending from, the cushion, each stabilizing member being adapted to contact the face of the patient in the adjacent nasal region below the orbital bone ridge in such a manner that strapping forces, which would otherwise be directed near the nares of the patient, are instead concentrated onto the patient's maxilla.

First claim

What is claimed is:

1. A patient interface device comprising:
a cushion defining a cavity therein, the cushion having a first side and an opposite second side with the cavity defined between the first side and the second side;
a headgear coupled to the cushion adjacent the first side of the cushion, the headgear comprising at least one strap for use in securing the cushion to the head of a patient,
wherein the cushion comprises:
an aperture formed in the second side of the cushion providing access to the cavity, the aperture having a periphery adapted to sealingly engage about the nostrils of the patient when the cushion is disposed on the face of the patient; and

a pair of stabilizing members directly coupled to, and extending upward from, the second side of the cushion, each stabilizing member being adapted to contact the face of the patient in a region adjacent to, but spaced from, the nose of the patient and below the orbital bone ridge of the patient in such a manner that strapping forces resulting from tightening of the at least one strap of the headgear, which would otherwise be directed near the nares of the patient, are instead concentrated onto outer portions of the patient's maxilla away from the nares, nose, and upper lip of the patient, and wherein each of the stabilizing members is integrally formed with the cushion; and
a generally rigid elongated front portion coupled to the first side of the cushion, wherein the headgear is coupled to the cushion via the elongated front portion.

2. The patient interface device of claim 1 , wherein the stabilizing members are disposed on opposite sides of the aperture.

3. The patient interface device of claim 1 , wherein each of the stabilizing members are bounded by a grooved portion which is structured to allow each stabilizing member to articulate with respect to the cushion.

4. The patient interface device of claim 3 , wherein the grooved portion comprises a baffle.

5. The patient interface device of claim 3 , wherein the grooved portion comprises a locally thinned wall section.

6. The patient interface device of claim 1 , wherein the stabilizing members are formed separately from, and selectively coupled to, the cushion.

7. The patient interface device of claim 1 , wherein each stabilizing member comprises a cavity formed therein, and wherein the cavity of each stabilizing member is filled with one or more of a low durometer gel or foam.

8. The patient interface device of claim 1 , wherein the cushion comprises a cradle shaped elongate hollow body and wherein the first side is of a generally convex shape and wherein the opposite second side is of a generally concave shape.

9. The patient interface device of claim 8 , further comprising a generally rigid elongated front portion coupled to the first side of the cushion, the front portion having a first end, an opposite second end and an aperture disposed therebetween, wherein the aperture is adapted to be coupled to a patient circuit, and wherein each of the first end and opposite second end are adapted to be selectively coupled to a headgear for use in securing the patient interface device to the head of a patient.

10. The patient interface device of claim 9 , wherein the front portion is coupled to the first side of the cushion via a hollow articulating portion.

11. The patient interface device of claim 10 , wherein the hollow articulating portion includes an inward curved U-shaped portion disposed along an upper portion thereof.

12. The patient interface device of claim 1 , further comprising a maxilla support assembly operatively coupled to the stabilizing members.

13. The patient interface device of claim 1 , wherein the elongated front portion is coupled to the first side of the cushion via a hollow articulating portion.

14. A patient interface device comprising:
a cushion defining a cavity therein, the cushion having a first side and an opposite second side; and
a headgear coupled to the cushion, the headgear comprising at least one strap for use in securing the cushion to the head of a patient,
wherein the cushion comprises:
an aperture formed in the second side providing access to the cavity, the aperture having a periphery adapted to sealingly engage about the nostrils of the patient when the cushion is disposed on the face of the patient; and
a pair of stabilizing members coupled to, and extending upward from, the cushion, each stabilizing member being adapted to contact the face of the patient in a region adjacent to, but spaced from, the nose of the patient and below the orbital bone ridge of the patient in such a manner that strapping forces resulting from tightening of the at least one strap of the headgear, which would otherwise be directed near the nares of the patient, are instead concentrated onto outer portions of the patient's maxilla away from the nares, nose, and upper lip of the patient,

wherein each stabilizing member comprises a cavity formed therein, and
wherein each cavity is in communication with the cavity of the cushion and wherein each cavity is adapted to be inflated by one or both of an applied system pressure and an exhalation pressure of the patient.

15. A cushion for use in a patient interface device, the cushion comprising:
a front side structured to be coupled to a headgear for securing the cushion to a patient;
an aperture formed in a patient facing side opposite the front side, the aperture providing access to a cavity defined within the cushion between the front side and the patient facing side, the aperture having a periphery adapted to sealingly engage about the nostrils of a patient when the cushion is disposed on the face of a patient; and
a pair of stabilizing members coupled to, and extending rearward and upward from, the patient facing side of the cushion, each stabilizing member being adapted to contact the face of the patient in a region adjacent to, but spaced from, the nose and below the orbital bone ridge of the patient in such a manner that strapping forces, which would otherwise be directed near the nares of the patient, are instead concentrated onto the patient's maxilla away from the nares, nose and upper lip of the patient,
wherein each of the stabilizing members is integrally formed with the cushion, wherein each stabilizing member comprises a cavity formed therein, wherein each cavity is in communication with the cavity of the cushion, and wherein each cavity is adapted to be inflated to one or both of an applied system pressure and an exhalation pressure of the patient.

16. The cushion of claim 15 , wherein the stabilizing members are disposed on opposite sides of the aperture.

17. The cushion of claim 16 , wherein each of the stabilizing members are bounded by a grooved portion which is structured to allow each stabilizing member to articulate with respect to the cushion.

18. The cushion of claim 17 , wherein the grooved portion comprises a baffle.

19. The cushion of claim 15 , further comprising a generally rigid elongated front portion coupled to the first side of the cushion, wherein the elongated front portion is structured to be coupled to the headgear for securing the cushion to a patient.

20. The cushion of claim 19 , wherein the elongated front portion is coupled to the first side of the cushion via a hollow articulating portion.
