INTERFACE

摘要

The present invention provides an interface that includes an inflatable envelope (that could also be referred to as a bag or balloon) having a supple wall structure. The inflatable envelope has a pair of locating protrusions that engage in the nostrils of the user. The locating protrusions supply gases flow to the user from inside the envelope. The envelope is so supple, and of sufficient dimension and shape, that when the inflated envelope is pressed against the face of a user, with the locating protrusions engaged in the nostrils of the user, the envelope contacts the surfaces of the user's face (the nose, the upper lip and the cheeks) and provides a seal.
