1. A nasal prong for a cushion member adapted for use with a patient interface device, the nasal prong comprising:
- a casing;
a flap extending from the casing and being adapted to be inserted into a nostril of a patient;
a bottom cap, wherein the casing and the bottom cap form an enclosed space; and
a fill material disposed in the enclosed space formed by the casing and the bottom cap, wherein the casing is structured to deform and conform to a shape of a portion of the nostril when the nostril applies pressure to the casing, and wherein the fill material includes at least one of a gel material or a liquid material,wherein the casing includes a depression formed therein, wherein the casing is structured such that a first end of the depression is a first distance from the bottom cap, a second end of the depression is a second distance from the bottom cap, and a central point of the depression is a third distance from the bottom cap, wherein the central point of the depression is equidistant from the first and second ends of the depression, wherein the casing is structured such that the first and second distances are both greater than the third distance when pressure is not applied to the casing, wherein the first end or the second end of the depression is located at a point where the casing meets the flap, and wherein the flap extends from the casing in a direction away from the enclosed space and does not form any of an outer perimeter of the enclosed space.

Abstract
A nasal prong for a cushion member for use with a patient interface device that includes a casing, a flap extending from the casing for insertion into a nostril of a patient, and a bottom cap. The casing and the bottom cap define a space. A fill material is disposed in the space defined by the casing and the bottom cap, wherein the casing is structured to deform and conform to a shape of a portion of the nostril when the nostril applies pressure to the casing.

11. A patient interface device comprising:
a cushion member having a nasal prong comprising; a casing; a flap extending from the casing and being adapted to be inserted into a nostril of a patient; a bottom cap, wherein the casing and the bottom cap form an enclosed space; and a fill material disposed in the enclosed space formed by the casing and the bottom cap, wherein the casing is structured to deform and conform to a shape of a portion of the nostril when the nostril applies pressure to the casing, and wherein the fill material includes at least one of a gel material or a liquid material, wherein the casing includes a depression formed therein, wherein the casing is structured such that a first end of the depression is a first distance from the bottom cap, a second end of the depression is a second distance from the bottom cap, and a central point of the depression is a third distance from the bottom cap, wherein the central point of the depression is equidistant from the first and second ends of the depression, wherein the casing is structured such that the first and second distances are both greater than the third distance when pressure is not applied to the casing, wherein the first end or the second end of the depression is located at a point where the casing meets the flap, and wherein the flap extends from the casing in a direction away from the enclosed space and does not form any of an outer perimeter of the enclosed space. - View Dependent Claims (12, 13, 14)

15. A nasal prong for a cushion member adapted for use with a patient interface device, the nasal prong comprising:
-
a casing; a first flap extending from the casing and being adapted to be inserted into a nostril of a patient; a bottom cap, wherein the casing and the bottom cap form an enclosed space; a fill material disposed in the enclosed space defined by the casing and the bottom cap; and a second flap disposed between the casing and the nostril of the patient, wherein the casing is structured to deform and conform to a shape of a portion of the nostril and press against the second flap when the nostril applies pressure to the casing causing the second flap to conform to and to form a seal with the nostril of the patient, wherein the casing includes a depression formed therein, wherein the casing is structured such that a first end of the depression is a first distance from the bottom cap, a second end of the depression is a second distance from the bottom cap, and a central point of the depression is a third distance from the bottom cap, wherein the central point of the depression is equidistant from the first and second ends of the depression, wherein the casing is structured such that the first and second distances are both greater than the third distance when pressure is not applied to the casing, wherein the first end or the second end of the depression is located at a point where the casing meets the first flap, and wherein the first flap does not define the enclosed space, and wherein the first flap extends from the casing in a direction away from the enclosed space and does not form any of an outer perimeter of the enclosed space.
