A miniature nasal mask (12) for supplying breathing gas to a human user through an interface with the user's nares (124), the interface being maintained by a contact seal (52) which engages the user's face only within an area between the tip (120) and immediately adjacent lateral flanks (122) of the user's nose adjacent to the nares (124), and the user's upper lip (126). The mask (12) may include cannulae (150) for delivery of breathing gas to the nares (124) of the user in a generally anterior to posterior direction with respect to the head of the user. Head gear for retaining a respiratory appliance (12) with respect to the face of a user without engaging the user's ears (15) includes ear piece means (16) for engaging side portions of the user's head, at least partially surrounding the user's ears (15). <IMAGE> |
