Abstract

An apparatus for delivering a flow of breathable gas to a patient for the treatment of Sleep Disordered Breathing (SDB) that is less obtrusive includes a nasal cannula, cannulae (2a, 2b), prongs, or pillows and may be sealed or unsealed with the nares of the patient in use. The cannula, pillows or prongs may be positioned on the face of the patient by a headgear (6). The cannula, pillows or prongs may be smaller, lighter, and/or less visible than other nasal cannula, cannulae, pillows or prongs and may therefore be less obtrusive to the patient.

Claims45

Dependent claims

A patient interface for delivering a flow of breathable gas to a patient, the patient interface comprising:

a barrel comprising a first end and a second end, a tubular portion extending between the first end and the second end, and a pair of nasal prongs extending from the tubular portion;
and
a tube connector configured to connect a tube or cannula to the barrel, the tube connector comprising a first end configured to be inserted into the first end or second end of the barrel, and a second end configured to be inserted into the tube or cannula, the first and second ends being divided by a flange with first and second sides, the first side being adapted to directly engage the barrel and the second side being adapted to directly engage the tube or cannula when the tube or cannula is connected to the barrel,
wherein the barrel is rotatable relative to the tube connector and the first and second sides of the flange are substantially parallel to each other.
