Problems solved by technology

However, such streams can cause an uncomfortable jetting sensation to the patient
Such a jet may be caused by breathing gases impinging at a relatively high velocity on a limited area of ​​the patient via the narrow orifice, and it may cause drying and irritation of such an area
Furthermore, such impacts may give the patient the perception that the pressure of the breathing gas is high, when the actual pressure is not so high, which is also undesirable

Embodiment Construction

[0025] 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 the parts are joined together, directly or indirectly (i.e., through one or more intermediate parts or components) or run together whenever linking 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.

[0026] As used herein, the word "unitary" means that a component is created as a single piece or unit. That is, a component that includes pieces that are created separately and then coupled together as a unit is not a "unitary" component or body. As employed herein, the statement that two or more parts or components "engage" one a...

Abstract

An adjustable airflow diffuser for selectively diffusing a flow of treatment gas includes a first member adapted to be disposed in the flow and a second member movably coupled to the first member and also adapted to be disposed in the flow. The second member is selectively moveable from: (i) a first position with respect to the first member in which the first member and the second member form a first turbulating arrangement, and (ii) a second position with respect to the first member in which the first member and the second member form a second turbulating arrangement.

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. 62 / 093869, filed December 18, 2011, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates generally to systems for providing a flow of treatment gas to the airway of a patient, and more particularly to adjustable gas flow diffusers for use in such systems. Background technique [0004] In many instances it is necessary or desirable to deliver a flow of breathable gas to a patient's airway in a non-invasive manner, ie, without intubating the patient or surgically inserting a tracheal tube into his esophagus. For example, it is known to ventilate a patient using a technique known as non-invasive ventilation. It is also known to deliver continuous positive airway pressure (CPAP) or variable airway pressure that varies with the patient's breathing cycle to...
