1. An interface assembly comprising:
- a user interface comprising a nasal cannula arrangement comprising;
at least one nasal prong, said prong having a gas outlet adapted to be inserted into a user'"'"'s nare and a gas inlet fluidly connected to the gas outlet,a patient facing rear surface extending generally laterally outward from the at least one nasal prong, and a lip extending about at least a portion of a perimeter of the rear surface; and
a securement system for at least one of the user interface and a component associated with the user interface, the securement system comprising a two-part releasable attachment arrangement, the two-part releasable attachment arrangement comprising;
a dermal patch and a user interface patch,the dermal patch comprising a patient side and an interface side,the patient side of the dermal patch configured to attach to the skin of a user,the interface side of the dermal patch comprising a first part of the two-part releasable attachment arrangement, andthe user interface patch comprising an interface side and patient side,the patient side of the user interface patch comprising a second part of the two-part releasable attachment arrangement, the second part being complementary to the first part,the interface side of the user interface patch being attachable to at least one of the user interface and the component associated with the user interface,the rear surface of the user interface configured for receiving or retaining the user interface patch such that the user interface patch is capable of being releasably attachable or connectable to, or with, the dermal patch and the lip at least partially bounds the user interface patch, wherein the dermal patch is configured to be affixed to a user'"'"'s face.

Abstract
Medical breathing tubes have a tubular body that defines a lumen extending between open terminal ends of the tubular body. An internal form is enclosed within the lumen and supportive of the tubular body. The internal form may be a coated encapsulated internal form where the coating secures the internal form to the tubular body. The internal form may provide for a series of alternative crests and troughs of the tubular body. A patient interface and/or a securement system may be attached to the tubular body.
