Nasal cannula for a nasal interface

Nasal cannula

Cannula pad

A patient interface assembly has a patient interface and a securement system for the patient interface and/or patient interface tubing. The patient interface has a body and at least one nasal prong extending from the body. The at least one nasal prong has a gas inlet for fluid communication with a supply of breathable gas, and a gas outlet configured to direct a flow of gas towards a nare of the user's nose. The at least one nasal prong further includes an exterior surface, at least a portion of the exterior surface is a sealing surface configured to seal the nare of the user's nose. The securement system has a two-part releasable attachment or connection arrangement, the arrangement comprising a first patch and a second patch.

Nasal cannula and securement system

A patient interface, such as a nasal cannula is described. The patient interface has a body portion to be located, in-use upon a face of a user. The body portion has at least one side arm that extends laterally from a central bridge portion to be located about a user's septum region, where each side arm is connected to a resilient, or relatively more rigid, bridge portion element. The interface has at least one, and preferably a pair of, nasal prong(s). The body portion has at least one fluid passageway connected to the nasal prong(s) for supply of a gas to the nare(s) of the user's nose. A cross section of the passageway varies along the length of the body portion to regions of varying flexibility along the body portion. The bridge portion element defines a substantially predetermined spatial relationship for outlet(s) of a gas delivery system supplying gas via each side arm to the outlet(s) from which, for example, the nasal prong(s) may be provided in fluid connection. Each side arm may comprise one or more predefined or predisposed points or localised compensation regions (or sites) positioned along the side arm, or a side arm element, to accommodate or facilitate a compensation of the patient interface in or at one or more of the compensation regions (or sites).
