Abstract
A patient interface device (2) includes a frame member (4) and a cushion (6) having a main body, a sealing portion, and first and second posts extending from the main body. The frame member defines a first orifice and a second orifice. The first post of the cushion is rotateably received within the first orifice and the second post is rotateably received within the second orifice in a manner that permits the cushion to rotate relative to the frame member.
Claims19
A patient interface device, comprising:
- a frame member defining a first orifice and a second orifice, the frame member including a generally annular central member defining a central orifice, a first main arm that extends from a first side of the central member and a second main arm extends from a second side of the central member;
- and
- a cushion having a main body, a sealing portion provided at a first end of cushion, and a first post extending from a first side of the main body and a second post extending from a second side of the main body, wherein a second end of the cushion opposite the sealing portion defines a fluid coupling orifice structured to be coupled to a fluid connector, wherein the second end including the fluid coupling orifice is inserted through the central orifice of the central member of the frame member, and wherein the first post is rotateably received within the first orifice and the second post is rotateably received within the second orifice in a manner that permits the cushion to rotate relative to the frame member.

A method of adjusting a patient interface device structured to deliver a flow of breathing gas to an airway of a patient, comprising:
- (a) donning the patient interface device, wherein the patient interface device includes:
- a frame member defining a first orifice and a second orifice, the frame member including a generally annular central member defining a central orifice, a first main arm that extends from a first side of the central member and a second main arm extends from a second side of the central member;
- and
- a cushion having a main body, a sealing portion provided at a first end of cushion, and a first post extending from a first side of the main body and a second post extending from a second side of the main body, wherein a second end of the cushion opposite the sealing portion defines a fluid coupling orifice structured to be coupled to a fluid connector, wherein the second end including the fluid coupling orifice is inserted through the central orifice of the central member of the frame member, and wherein the first post is rotateably received within the first orifice and the second post is rotateably received within the second orifice in a manner that permits the cushion to rotate relative to the frame member;
- and
- (b) causing the cushion to rotate relative to the frame member when the sealing portion is engaged with the face of the patient.
A cushion for a patient interface device, comprising:
- a main body;
- a sealing portion provided at a first end the main body, wherein a second end of the main body opposite the sealing portion defines a fluid coupling orifice structured to be coupled to a fluid connector;
- a first post extending from a first side of the main body and structured to be rotateably received within a first orifice of a frame member of the patient interface device;
- and
- a second post extending from a second side of the main body and structured to be rotateably received within a second orifice of a frame member of the patient interface device, wherein the first post and the second post are cylindrical and wherein the first post and the second post each include an inner cylindrical portion, an outer cylindrical portion, and an enlarged portion provided between the inner cylindrical portion and the outer cylindrical portion.
