Embodiment Construction

[0026] As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. As used herein, the statement that two or more parts or components are "coupled" shall mean that those parts are joined or operate together, directly or indirectly (i.e., through one or more intermediate parts or components), provided that Just get in touch. As used herein, "directly coupled" means that two elements are in direct contact with each other. As used herein, "fixedly coupled" or "fixed" means that two components are coupled so as to move as one while maintaining a constant orientation relative to each other.

[0027] As used herein, the word "unitary" means that a component is produced as a single piece or unit. That is, a component that includes parts that are created separately and then coupled together as a unit is not a "unitary" component or body. As used herein, the statement that two or more parts or components "engage" eac...

Abstract

A cushion for use in a system providing a flow of breathing gas to the airway of a patient includes a first end having a sealing flap structured to sealingly engage a surface of the patient about an airway of the patient and a second end adapted to receive the flow of breathing gas. A wall portion extends between the first end and the second end and defines a passage which extends between the first end and the second end and which is structured to communicate the flow of breathing gas from the second end to the first end. The wall portion includes a notch which is positioned and structured todeform in a predetermined manner such that an angle which the wall portion makes with a longitudinal axis of the passage increases from a first value to a second value upon deformation of the notch.

Description

[0001] Cross References to Related Applications [0002] Pursuant to 35 U.S.C. § 119(e), this patent application claims priority to U.S. Provisional Application No. 62 / 438,499, filed December 23, 2016, the contents of which are incorporated by reference at In this article. technical field [0003] The present invention relates generally to a cushion for use on a patient interface device in a pressure support system that provides airflow to a patient's airway, and more particularly to a cushion wherein the At least one portion includes a structure that prevents buckling in the sealing portion of the gasket. The invention also relates to a system for delivering a flow of breathing gas to the airway of a patient comprising such a cushion. Background technique [0004] There are many situations in which it is necessary or desirable to deliver a flow of breathing gas to a patient's airway in a non-invasive manner (ie, without intubating the patient or surgically inserting an en...
