Embodiment Construction

[0028] As used herein, the singular forms "a", "an" and "the" include plural unless the context clearly dictates otherwise. As used herein, the statement that two or more parts or components are "coupled" means that the parts are coupled or operate together, directly or indirectly, ie, through one or more intermediate parts or components, wherever 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 for movement as one while maintaining a constant orientation relative to each other.

[0029] As used herein, the word "unitary" means that a component is formed as a single part or assembly. That is, it is not a "unitary" part or body that includes parts that are formed separately and then coupled together into an assembly. As used herein, the statement that two or more parts or components "engage" one another shall mean that the pa...

Abstract

A patient interface device (2, 60, 160, 204) includes a cushion (8, 66, 210), a frame (10, 68, 162, 206) having a faceplate portion. The cushion is coupled to the frame. The faceplate portion has a main orifice and holes adjacent the main orifice. The device further includes a coupling conduit (6, 64, 164, 212) having an inlet end, an outlet end coupled to the inlet end, and a hood member having openings provided on an outer periphery thereof. The inlet end is structured to receive a flow of breathing gas. The outlet end is coupled to the main orifice to deliver the flow of breathing gas to the main conduit. The hood member surrounds the outlet end and is disposed over the holes such that exhalation gasses will through the holes and be captured by the hood member and directed through the openings.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority under 35 U.S.C §119(e) to U.S. Provisional Application No. 61 / 405,799, filed October 22, 2010, the contents of which are hereby incorporated by reference. field of invention [0003] The present invention relates to non-invasive ventilation and pressure support systems, and more particularly to a patient interface device that can be used by such systems to deliver gas to a patient, the device including a device for reducing the noise caused by the patient's exhalation and / or allowing the patient Exhaust assembly for diffused exhalation airflow. Background technique [0004] There are many situations in which it is necessary or desirable to deliver breathing gases non-invasively to a patient's airway, ie without intubating the patient's airway or surgically inserting a tracheal tube in his esophagus. For example, it is known to ventilate a patient using a technique known as non-i...
