Abstract

This invention relates to a patient interface and component parts which may be integrated or form a part of an assembled interface for use by a user. In various embodiments, the component parts may include: a component may be provided as a clip for supporting a gas supply tube to the interface; a buckle may be provided at an end of a headgear strap for releasable attachment to the interface; a manifold part of a patient interface may be attachable to the interface in a manner allowing for adjustment or re-orientation such that an associated gas supply conduit is re-routed to be to a left—or a right-side of the interface (or user); one or a pair of support side arms of the interface may be configured to be twisted or bent so as to more comfortably accommodate the shape of a user's face upon which they are to be located in use; parts of a manifold at the connection of a gas supply tube to the interface may be configured to be of a multi-part manifold assembly.

First claim

1 . (canceled)

2 . A patient interface comprising:
a frame section adapted to be positioned on a face of a user, the frame section comprising a gases chamber adapted to channel gases to the user and two nasal delivery elements extending from the gases chamber each adapted to be located in a nare of the user to form an unsealed engagement; and a rotatable assembly, which is rotatably secured to the frame section, the rotatable assembly being configured to rotate relative to the frame section.

3 . The patient interface of claim 2 , wherein a range of rotary motion between the rotatable assembly and the frame section is a full 360 degrees.

4 . The patient interface of claim 2 , wherein the patient interface further comprises a retention mechanism, the retention mechanism being configured to retain the rotatable assembly in an operational position.

5 . The patient interface of claim 2 , wherein the frame section comprises a relatively rigid section and a relatively flexible section, the two nasal delivery elements extending from the relatively flexible section of the frame section.

6 . The patient interface of claim 2 , wherein a range of rotary motion between the rotatable assembly and the frame section is a full 360 degrees.

7 . The patient interface of claim 2 , wherein the patient interface further comprises a retention mechanism, the retention mechanism being configured to retain the rotatable assembly in an operational position.

8 . The patient interface of claim 4 , wherein the retention mechanism comprises a first retention feature disposed on the rotatable assembly and a second retention feature disposed on the frame section.

9 . The patient interface of claim 2 , wherein the frame section further comprises a track, the track being configured to guide rotation of the rotatable assembly relative to the frame section.

10 . The patient interface of claim 2 , wherein the rotatable assembly comprises a boss adapted to rotatably move in a complementary track of the frame section, the complementary track comprising detention regions for restraining motion of the boss.

11 . The patient interface of claim 8 , wherein the first retention feature is integrally formed with the frame section and the second retention feature is integrally formed with the rotatable assembly.

12 . The patient interface of claim 2 , wherein the frame section comprises a relatively rigid section and a relatively flexible section, the two nasal delivery elements extending from the relatively flexible section of the frame section.

13 . The patient interface of claim 5 , wherein the relatively flexible section of the frame section is a separately formed component that is assembled with the relatively rigid section of the frame section.

14 . The patient interface of claim 5 , wherein the relatively flexible section provides a soft interfacing component to the user for comfortably delivering a flow of gases through the two nasal delivery elements, the relatively flexible section being preferably formed of Silicone.

15 . The patient interface of claim 5 , wherein the relatively flexible section comprises an elongate base portion from which the two nasal delivery elements extend, a plurality of side arms extending laterally from either side of the elongate base portion, wherein the plurality of side arms are preferably formed integrally with the elongate base portion.

16 . The patient interface of claim 2 , wherein the rotatable assembly is a manifold.

17 . The patient interface of claim 2 , wherein the rotatable assembly comprises an axle structure about which rotational motion between the rotatable assembly and the frame section can occur, the axle structure preferably protruding through an aperture in the frame section.

18 . The patient interface of claim 17 , wherein the frame section comprises a contact region that sits under nares of a user in use and a non-contact region that faces away from the user in use, the axle structure being provided at the non-contact region of the frame section.

19 . The patient interface of claim 2 , wherein the frame section comprises a first side arm and a second side arm, the first side arm and the second side arm extending laterally from the frame section on substantially opposing sides of the frame section.

20 . The patient interface of claim 19 , wherein a distal end of each side arm comprises a formation configured to releasably couple a complementary connector of a headgear.

21 . The patient interface of claim 2 , wherein a base of the two nasal delivery elements includes a curved surface to provide for smoother gases flow.
