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

What is claimed:

1. A patient interface for delivering a supply of gases to a patient, the patient interface comprising:
a tubular body portion for receiving and directing a gas supply to an outlet, the outlet comprising a pair of non-sealing prongs;
a pair of elongate side arms extending outward relative to opposite sides of the tubular body portion to contact a patient's face,
wherein each of the pair of elongate side arms includes a proximal end adjacent to the tubular body portion and an opposite distal end,
wherein the pair of elongate side arms are configured to aid in stabilizing the patient interface on the patient's face; and

a twisted portion located along a length of each of the pair of elongate side arms, the twisted portion being twisted about a longitudinal axis of the twisted portion in an absence of applied forces to the proximal end and the opposite distal end of the elongate side arms, wherein the twisted portion includes a first orthogonal cross-section and a second orthogonal cross-section, the first orthogonal cross-section closer to the proximal end than the second orthogonal cross-section,
wherein the second orthogonal cross-section is rotated at an angle relative to the first orthogonal cross-section, and
wherein an orthogonal cross-section of each of the pair of side arms decreases along the length of each of the pair of side arms from the proximal end to the opposite distal end.

2. The patient interface of claim 1 , wherein the tubular body portion comprises a manifold.

3. The patient interface of claim 1 , wherein the second orthogonal cross-section is rotated in at least one of a clockwise and counterclockwise direction.

4. The patient interface of claim 1 , wherein the angle the second orthogonal cross-section is rotated relative to the first orthogonal cross-section is less than or equal to 45 degrees.

5. The patient interface of claim 1 , wherein the twisted portion of each of the pair of elongate side arms is proximal to a distal end of each of the pair of elongate side arms.

6. The patient interface of claim 1 , further including a curve along the length of each of the pair of side arms, wherein each of the pair of side arms includes:
a first portion extending laterally away from the tubular body portion at a first angle, and
a second portion extending from the first portion at a second upward angle.

7. The patient interface of claim 6 , wherein the first portion and the second portion are joined by an intermediate curved portion.

8. The patient interface of claim 6 , wherein the second upward angle is between 20 and 70 degrees.

9. The patient interface of claim 1 , wherein each of the pair of side arms are shaped to engage the patient's face below cheekbones of the patient.

10. The patient interface of claim 1 , wherein a distal end of each of the pair of side arms is configured to releasably couple with a connector of a headgear.

11. A patient interface for delivery of a supply of gases to a patient, the patient interface comprising:
a nasal cannula having a face mount portion;
a first nasal prong and a second nasal prong extending from the face mount portion, the first nasal prong and the second nasal prong being nonsealing;
a tubular body portion configured to direct a gas supply to the first nasal prong and the second nasal prong;
a pair of elongate side arms extending away from opposite sides of the tubular body portion to contact a patient's face, wherein the pair of elongate side arms are configured to stabilize the patient interface on the patient's face; and
a twisted portion located along a length of each of the pair of elongate side arms, the twisted portion being twisted about a longitudinal axis of the twisted portion in an absence of applied forces to the pair of elongate side arms,
wherein the twisted portion includes a first orthogonal cross-section and a second orthogonal cross-section, the first orthogonal cross-section proximal to the second orthogonal cross-section,
wherein the twisted portion is adjacent to a distal end of each of the pair of elongate side arms relative to the tubular body portion,
wherein the second orthogonal cross-section is rotated at an angle relative to the first orthogonal cross-section, and
wherein an orthogonal cross-section of each of the pair of side arms decreases along the length of each of the pair of side arms from the proximal end to the opposite distal end.

12. The patient interface of claim 11 , wherein the first nasal prong and the second nasal prong are integrally formed with the face mount portion.

13. The patient interface of claim 11 , wherein the tubular body portion comprises a manifold.

14. The patient interface of claim 11 , wherein the second orthogonal cross-section is rotated in at least one of a clockwise and counterclockwise direction.

15. The patient interface of claim 11 , wherein the face mount portion is shaped and configured to conform to the patient's face around an upper lip area.

16. A patient interface for delivery of a supply of gases to a patient, the patient interface comprising:
a nasal cannula having a face mount portion;
a first nasal prong and a second nasal prong extending from the face mount portion, the first nasal prong and the second nasal prong being sized and configured to be nonsealing;
a tubular body portion configured to direct a gas supply to the first nasal prong and the second nasal prong, wherein the tubular body portion is connectable to a body of the face mount portion in two directions;
a pair of elongate side arms extending away from opposite sides of the tubular body portion to contact a patient's face, wherein the pair of elongate side arms are configured to stabilize the patient interface on the patient's face; and
a twisted portion located along a length of each of the pair of elongate side arms,
wherein the twisted portion includes a first orthogonal cross-section and a second orthogonal cross-section, the first orthogonal cross-section proximal to the second orthogonal cross-section,
wherein the second orthogonal cross-section is rotated at an angle relative to the first orthogonal cross-section,
wherein the twisted portion remains twisted in an absence of applied forces to opposing ends of each of the pair of elongate side arms, and
wherein an orthogonal cross-section of each of the pair of side arms decreases along the length of each of the pair of side arms from the proximal end to the opposite distal end.

17. The patient interface of claim 16 , wherein the first nasal prong and the second nasal prong are integrally formed with the face mount portion.
