## Abstract

A single use mask having an adhesive gasket is provided. The mask is of a two piece construction including a relatively hard attachment shell and a flexible gasket. The shell serves at the air chamber covering the mouth and nose of the patient as well as the point of attachment for the therapy tubing set. The flexible gasket and adhesive layer serves as the attachment means for affixing the mask to the patient's face. In contrast to the masks of the prior art, the gasket is formed from a sheet of foam material.

## Claims

### Claim 1

A breathing mask comprising:
a shell, said shell having an attachment port for interfacing with a breathing apparatus, said shell having an interior volume and an interior surface area; and
a gasket affixed to a periphery of said shell, said gasket having an adhesive on an interior surface thereof and an adhesive surface area, wherein said adhesive surface area is greater than said interior surface area.

### Claim 2 (depends on 1)

The breathing mask of claim 1, wherein said adhesive surface area is at least twice said interior surface area.

### Claim 3 (depends on 1)

The breathing mask of claim 1, wherein said adhesive surface area is at least three times said interior surface area.

### Claim 4 (depends on 1)

The breathing mask of claim 1, said shell further comprising:
an outer shell layer; and
an inner shell layer, said inner shell having an interior volume and an interior surface area, said attachment port extending through said inner and outer shell layers and in fluid communication with said interior volume, wherein said adhesive surface area is greater than said interior surface area of said inner shell layer.

### Claim 5 (depends on 4)

The breathing mask of claim 4, wherein said adhesive surface area is at least twice said interior surface area of said inner shell layer.

### Claim 6 (depends on 4)

The breathing mask of claim 4, wherein said adhesive surface area is at least three times said interior surface area of said inner shell layer.

### Claim 7 (depends on 4)

The breathing mask of claim 4, wherein said outer shell layer and said inner shell layer cooperate to provide structural stability for said shell.

### Claim 8 (depends on 1)

The breathing mask of claim 1, said gasket comprising:
a thermoformed foam material contoured to generally approximate a patient's facial contour.

### Claim 9 (depends on 1)

The breathing mask of claim 1, said gasket comprising:
an outer layer;
an inner layer, wherein the flange of said shell is retained between said inner and outer layers; and
an adhesive layer applied to an inner surface of said inner layer.

### Claim 10 (depends on 1)

The breathing mask of claim 1, wherein said outer and inner layers are a thermoformed foam material contoured to generally approximate a patient's facial contour.

### Claim 11

A method of forming a breathing mask comprising:
forming a shell, said shell having an attachment port for interfacing with a breathing apparatus, said shell having an interior volume and an interior surface area; and
affixing a gasket to a periphery of said shell, said gasket having an adhesive on an interior surface thereof and an adhesive surface area, wherein said adhesive surface area is greater than said interior surface area.

### Claim 12 (depends on 11)

The method of claim 11, wherein said adhesive surface area is at least twice said interior surface area.

### Claim 13 (depends on 11)

The method of claim 11, wherein said adhesive surface area is at least three times said interior surface area.

### Claim 14 (depends on 11)

The method of claim 11, the step of forming said shell further comprising:
forming an outer shell layer; and
forming an inner shell layer, said inner shell having an interior volume and an interior surface area
placing said inner shell within said outer shell, said attachment port extending through said inner and outer shell layers and in fluid communication with said interior volume, wherein said adhesive surface area is greater than said interior surface area of said inner shell layer.

### Claim 15 (depends on 11)

The method of claim 11, said gasket comprising:
a thermoformed foam material contoured to generally approximate a patient's facial contour.

### Claim 16 (depends on 11)

The method of claim 11, said gasket comprising:
an outer layer;
an inner layer, wherein the flange of said shell is retained between said inner and outer layers; and
an adhesive layer applied to an inner surface of said inner layer.
