The at least one nozzle is outside the user's nostrils.
Claims18
A device for providing gas to the nostrils of a user, comprising:
- two gas distribution nozzles;
- and
- means for supporting said two gas distribution nozzles, said means for supporting holding said two gas distribution nozzles close to or in contact with a face of the user and along at least part of an outer surface of a nose of the user, when the device is positioned on a head of a user,
- said two gas distribution nozzles having gas exits spaced from a nostril of a user when the device is positioned on a head of the user so that after the gas exits each of said two gas distribution nozzles, the gas follows along the outer nasal wall of the nostrils of the user before the gas enters the nostrils.
A method for administering a gas to a user via a nasal route, comprising the steps of:
- directing the gas to two gas distribution nozzles situated close to or in contact with a face of the user and arranged along at least part of an outer nasal wall of a nose of the user;
- and
- delivering the gas through the two distribution nozzles in the direction of the nostrils of the user, the gas exiting the two gas distribution nozzles before reaching the nostrils and sweeping across at least part of the outer nasal wall of the nose of the user,
- the gas following along the outer nasal wall of each of the nostrils of the user before entering inside the nostrils.
A portable device for delivering a gas to a user from outside of nostrils of the user comprising:
- at least one nozzle for delivering the gas to the user;
- at least one supply line for supplying the gas from a supply source to said at least one nozzle;
- and
- means for attaching said at least one supply line to the user to stabilize the supply line,
- wherein the gas exits an end of said at least one nozzle outside the nostrils and flows along an outer wall of a nose of the user before entering the nostrils, and
- wherein said at least one supply line is attached to a bridge of a nose of the user.
