Multi-Chamber Mask and Method of Forming the Same
First Claim
1. A multi-chamber mask, comprising:
- a shell adapted to cover portions of a user'"'"'s face comprising the user'"'"'s mouth and at least portions of the user'"'"'s nose comprising the nostrils, the shell adapted to contact the user'"'"'s face surrounding the covered portions of the user'"'"'s face to substantially prevent gas from escaping between the shell and the contacted portions of the user'"'"'s face, the shell adapted to couple to a gas supply source; and
a partition coupled to the shell and cooperating with the shell to define a first chamber and a second chamber, the first chamber adapted to be positioned proximate the user'"'"'s nose to direct inflow of gas from the gas supply source to the user'"'"'s nasal passages, the second chamber adapted to be positioned proximate the user'"'"'s mouth to restrict outflow of gas from the user'"'"'s mouth in response to inflow of gas from the gas supply source to the user'"'"'s nasal passages, the partition adapted to restrict flow of gas between the first and the second chamber.

Abstract
A multi-chamber mask includes a shell and a partition. The shell is adapted to cover portions of a user'"'"'s face including the mouth and at least portions of the nose including the nostrils, the shell adapted to contact the face surrounding the covered portions of the face to substantially prevent gas from escaping between the shell and the contacted portions of the user'"'"'s face, and the shell is adapted to couple to a gas supply source. The partition is coupled to the shell and cooperates with the shell to define a first chamber and a second chamber, the first chamber adapted to be positioned proximate the user'"'"'s nose to direct inflow of gas from the gas supply source to the user'"'"'s nasal passages, the second chamber adapted to be positioned proximate the user'"'"'s mouth, the partition adapted to restrict flow of gas between the first and the second chamber.

9. A method of forming a multi-chamber mask, comprising:
-
providing a shell covering portions of a facial surface, the facial surface representing physical features of a user'"'"'s face, the covered portions comprising the area corresponding to the user'"'"'s mouth and at least a portion of the user'"'"'s nose comprising the nostrils;
providing a partition coupled to the shell and cooperating with the shell to define a first chamber and a second chamber, the first chamber adapted to be positioned proximate the user'"'"'s nose to direct inflow of gas from a gas supply source to the user'"'"'s nasal passages, the second chamber adapted to be positioned proximate the user'"'"'s mouth to restrict outflow of gas from the user'"'"'s mouth in response to inflow of gas from the gas supply source to the user'"'"'s nasal passages, the partition adapted to restrict flow of gas between the first and the second chamber. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of forming a multi-chamber mask, comprising:
-
providing a first layer of deformable material covering portions of a facial surface, the facial surface representing physical features of a user'"'"'s face, the covered portions of the facial surface comprising portions corresponding to the user'"'"'s mouth and at least a portion of the user'"'"'s nose comprising the nostrils;
providing one or more openings in the first layer of deformable material corresponding to the user'"'"'s mouth and nostrils;
providing one or more spacers covering at least a portion of the facial surface corresponding to the user'"'"'s mouth;
providing a second layer of deformable material over the one or more spacers and at least a portion of the first layer;
providing a partition between the first and second layers of deformable material adapted to cooperate with the first and second layers of deformable material to define a first chamber and a second chamber, the first chamber adapted to be positioned proximate the user'"'"'s nose to direct inflow of gas from a gas supply source to the user'"'"'s nasal passages, the second chamber adapted to be positioned proximate the user'"'"'s mouth to restrict outflow of gas from the user'"'"'s mouth in response to inflow of gas from the gas supply source to the user'"'"'s nasal passages, the partition adapted to restrict flow of gas between the first and the second chamber; and
coupling the first layer of deformable material to the second layer of deformable material, with the partition between the first and second layers of deformable material, to form the multi-chamber mask. - View Dependent Claims (18, 19, 20)
