The elbow assembly includes a swivel elbow that defines an intake port and an exhaust port separated from the intake port using a baffle. The elbow assembly includes an end portion that interfaces with the aperture of the frame.
Claims37
A respiratory mask assembly for delivering breathable gas to a patient, comprising:
- a frame having a front surface and a rear surface adapted in use to face the patient, the frame including a main body providing an aperture therethrough for the introduction of breathable gas into a nasal breathing cavity;
- and
- an elbow assembly swivelably coupled to the front surface of the frame, the elbow assembly including a swivel elbow that defines an intake port and an exhaust port separated from the intake port using a baffle provided within an interior portion of the swivel elbow,
- wherein the elbow assembly includes an end portion that interfaces with the aperture of the frame.
An elbow assembly for a respiratory mask assembly that delivers breathable gas to a patient, the elbow assembly comprising:
- a swivel elbow including a first end portion having a surface that is adapted to directly engage a surface of a gas delivery tube and a second end portion detachably and swivelably coupled to a frame,
- the swivel elbow defining an intake port and an exhaust port separated from the intake port using a baffle, the baffle being configured to direct exhaust gas away from a nasal breathing cavity defined by the frame in a first direction that is substantially opposite to a second direction in which the intake port delivers incoming gas to the nasal breathing cavity.
A respiratory mask assembly for delivering breathable gas to a patient, comprising:
- a frame having a front surface and a rear surface, opposite the front surface, and adapted in use to face the patient, the frame including an aperture provided through a main body thereof for the introduction of breathable gas to the patient;
- a cushion attachable to the frame;
- and
- a swivel elbow detachably coupled to the frame via a release mechanism positioned on the swivel elbow,
- wherein the aperture has an area of at least 180 mm2 and the patient can breath through the aperture when the swivel elbow is detached from the frame.
A respiratory mask assembly for delivering gas to a person, the mask assembly comprising:
- a frame having a front surface, and a rear surface which, in use, faces a person, the frame including a main body providing an aperture therethrough for the introduction of gas into a nasal cavity;
- and
- an elbow assembly swivelably coupled to the front surface of the frame, the elbow assembly including a swivel elbow,
- wherein the elbow assembly includes an end portion which interfaces with the aperture of the frame, wherein:
- the frame includes a flange which surrounds the aperture, and
- the flange is releasably engageable with a collar of a flexible quick release mechanism formed in the end portion of the elbow.
A respiratory mask assembly for delivering breathable gas to a patient, comprising:
- a frame having a front surface and a rear surface adapted in use to face the patient, the frame including a main body providing an aperture therethrough for the introduction of breathable gas into a nasal breathing cavity;
- and
- an elbow assembly swivelably coupled to the front surface of the frame, the elbow assembly including a swivel elbow,
- wherein the swivel elbow includes an end portion that is releasably engageable to a flange of the frame by pressing the end portion against the flange.
A respiratory mask assembly for delivering breathable gas to a patient, comprising:
- a frame having a front surface and a rear surface adapted in use to face the patient, the frame including a main body providing an aperture therethrough for the introduction of breathable gas into a nasal breathing cavity;
- and
- an elbow assembly swivelably coupled to the front surface of the frame, the elbow assembly including a swivel elbow,
- wherein the swivel elbow includes an end portion that is configured to releasably engage by a snap action to a flange of the frame.
