Benefits of technology

[0020]One aspect of the invention is directed towards a nasal assembly, in particular an improved cushion / frame / vent / clip assembly having an improved frame, cushion, vent and / or clip component. The assembly may effectively reduce the noise associated with gas washout or venting of the patient.
[0022]Another aspect of the invention is directed towards a frame that is easy and inexpensive to manufacture.
[0024]According to another aspect of the invention, the clip may have ribs to improve strength / stiffness, and / or to allow ease of grip. The clip may also have wings with compound curvature to help improve strength / stiffness.
[0033]Yet another aspect of the invention relates to a nasal assembly for delivering breathable gas to a patient. The nasal assembly includes a frame and a cushion including a pair of nozzles to communicate with nasal passages of a patient's nose in use. The cushion is coupled with the frame. The cushion includes a size indicator, a series of position arrows, text, and / or a logo provided to one side of the cushion. The size indicator, series of position arrows, text, and / or logo are adapted to provide a visual cue to assist the patient in achieving correct alignment and orientation of the cushion and frame with respect to the patient in use.

Problems solved by technology

Thus, adjustment of the fit or stability of the nasal assembly directly affects the seal, which can adversely affect patient comfort.
Similar to Trimble, adjustment of the fit or stability of the nasal assembly directly affects the seal, which can adversely affect patient comfort.
A common problem with known nasal assemblies, such as those discussed above, is patient comfort.
For example, the prongs tend to irritate the patient's nose due to the tension applied by the headgear assembly that pulls the rigid shell and prongs towards the patient's nose.
Another problem is achievement of a sealing fit with the patient's nasal passages without sacrificing patient comfort.
Another problem is irritation of the inside of the patient's nostrils caused by contact with the prongs, e.g., an edge thereof.
Another problem is irritation of the inside of the patient's nostrils caused by air jetting (air flow irritation) from the prongs.
Another problem is adjustment of the nasal assemblies relative to the nose and / or head of the patient so as to accommodate various shapes and angles of patient's noses.
Still another problem is the direct association between sealing and stability forces that can affect patient comfort.

Abstract

A nasal assembly for delivering breathable gas to a patient includes a frame having lateral connector, a cushion with a pair of nozzles, and a clip to secure the cushion to the frame. The frame includes a vent channel and a plurality of vent holes. The frame / cushion includes structure (lugs / cut outs) to prevent the assembly of an unvented frame with an unvented cushion, for safety purposes. The frame includes cored portions that interface with corner lugs provided on the cushion. A patient interface includes a frame, a cushion (nasal mask, nasal-oro mask, nozzles, etc.) and a vent assembly including a pattern of vent holes including at least two rows.

Description

CROSS REFERENCE TO APPLICATIONS[0001]This application claims the benefit of U.S. Design No. 29 / 258,084, filed Apr. 14, 2006, and U.S. Provisional Patent Application Nos. 60 / 734,282, filed Nov. 8, 2005, 60 / 758,200, filed Jan. 12, 2006, 60 / 795,615, filed Apr. 28, 2006, 60 / 819,626, filed Jul. 11, 2006, and 60 / 838,442, filed Aug. 18, 2006, each of which are incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to a nasal assembly used for treatment, e.g., of Sleep Disordered Breathing (SDB) with Continuous Positive Airway Pressure (CPAP) or Non-invasive Positive Pressure Ventilation (NPPV).BACKGROUND OF THE INVENTION[0003]Some nasal assemblies used in the treatment of SDB are designed for insertion into or adjacent the nasal passages of the patient. Air or other breathable gas is supplied by a blower and passed along a flexible conduit to the nasal assembly.[0004]The nasal assembly generally includes a relatively rigid shell, e.g., a ...
