Abstract: A retainer clip configured to engage a tubing member includes a base portion and a clamp portion which may be formed as a unitary structure. The base portion is generally disc-shaped and has a front side and a back side. The clamp portion is disposed on the base portion and extends upwardly from the front side and includes a spaced pair of clamp fingers which collectively define a slot that opens into a channel. The channel is adapted to frictionally engage the tubing member. The back side includes a layer of adhesive for adhering the retainer clip to the patient such as to the patient's skin. An interface assembly for delivering gas from a gas source to a patient includes a user interface, at least one tubing member extending from the user interface, and at least one of the retainer clips configured to anchor the tubing member to the patient.

Abstract: An integrated nasal mask is adapted for delivering gas to a patient and comprises a mask body and a pair of elongate nostril-engaging stems. The mask body is generally triangularly shaped and includes a nasal opening sized and configured to substantially envelope a patient's nose. The nasal opening opens to a nasal cavity. The nostril-engaging stems extend outwardly from the nasal cavity. Each one of the stems defines a fluid passageway for delivering gas to the patient's nose and for allowing discharge of exhalation gasses during the exhalation phase of the breathing cycle.
