Embodiment Construction

[0017] As used herein, the singular forms "a", "an" and "the" include plural reference unless expressly stated otherwise. As used herein, the statement that two or more parts or components are "coupled" means that these parts are directly or indirectly (ie, through one or more intermediate parts or components) joined together or operate together whenever a connection occurs. 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.

[0018] The word "unitary" as used herein means that a component is produced as a single piece or unit. That is, a component that includes multiple pieces 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" one anothe...

Abstract

A patient interface device includes a sealing cushion structured to communicate a flow of breathing gas within an airway of a patient, a rigid or semi rigid support member coupled to the sealing cushion, the support member including an inner surface, an outer surface and at least one orifice extending therethrough, and a cushion member pro not vided on the inner surface of the support member and structured to engage a portion of the head or face of the patient when the patient interface device is donned by the patient, the cushion member being made of a deformable material and overlapping the orifice such that a portion of the cushion member will flow at least partially through the orifice when pressure is applied to the cushion member.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 61 / 476,452, filed April 18, 2011, the contents of which are hereby incorporated by reference. field of invention [0003] The present invention relates to respiratory patient interface devices, and in particular, to patient interface devices having means for providing pressure relief for a deformable component, such as a cushion member configured to engage a patient's head or face . Background technique [0004] There are many situations where it is necessary or desirable to deliver a flow of breathing gas to a patient's airway in a non-invasive manner, ie without inserting a tube into the patient's body or surgically inserting an airway tube into their esophagus. For example, it is known to ventilate a patient using a technique known as non-invasive ventilation. It is also known to deliver positive airway pres...
