Abstract

A miniature nasal mask for supplying breathing gas to a human user through an interface with the user's nares, the interface being maintained by a contact seal which engages the user's face only within an area between the tip and immediately adjacent lateral flanks of the user's nose adjacent to the nares, and the user's upper lip.
