## Abstract

A flange extender for an ostomy bag comprises honey. In a preferred embodiment, the flange extender comprises a composition of hydrocolloid and medical grade Manuka honey and at least one release liner. Incorporation of honey into a flange extender provides additional adhesion to the skin of an ostomate and to a flange of an ostomy bag, increased wear time may possible and there may be reduced peristomal skin irritation. These advantages provide increased comfort for a user as well as reduced risk of infection through the antibacterial properties of honey.

## Claims

### Claim 1

A flange extender for extending a surface area of a flange used with an ostomy bag having an opening, wherein:
the flange extender comprises 0.01% to 2% honey by weight and 95% to 99.99% hydrocolloid by weight; and
the flange extender is arcuate, having a concave inner edge, the concave inner edge adapted to attach to a peripheral edge of the flange;
wherein at least two flange extenders have ends that are configured for: overlapping; and for alignment without overlapping; with each other, thereby forming an annulus when applied around the ostomy bag opening or to a peristomal area of skin of a user; and
wherein the honey and the hydrocolloid are configured for reducing skin irritation and/or inflammation.

### Claim 2 (depends on 1)

A flange extender according to claim 1, wherein the honey is medical grade Manuka honey.

### Claim 3 (depends on 1)

A flange extender according to claim 1, wherein the flange extender is translucent or opaque.

### Claim 4 (depends on 1)

A flange extender according to claim 1, wherein the flange extender comprises adhesive.

### Claim 5 (depends on 4)

A flange extender according to claim 4, wherein the adhesive is provided by the composition of the flange extender or is acrylic based or silicone-based or PU-based.

### Claim 6 (depends on 4)

A flange extender according to claim 4, wherein adhesive is applied to both the body facing surface and an ostomy bag facing surface of the flange extender.

### Claim 7 (depends on 4)

A flange extender according to claim 4, wherein the flange extender further comprises at least one release liner.

### Claim 8 (depends on 7)

A flange extender according to claim 7, wherein the release liner comprises a tab which does not adhere to the adhesive.

### Claim 9 (depends on 1)

A flange extender according to claim 1, wherein the flange extender has a width of about 20 mm to about 50 mm.

### Claim 10

A method of making a flange extender for extending a surface area of a flange used with an ostomy bag having an opening, the method comprising:
providing a composition configured for reducing skin irritation and/or inflammation, the composition comprising 0.01% to 2% honey by weight and 95% to 99.99% hydrocolloid by weight; and
providing a flange extender that is arcuate, having a concave inner edge, the concave inner edge adapted to attach to a peripheral edge of the flange; wherein at least two flange extenders have ends that are configured for: overlapping; and for alignment without overlapping; with each other, thereby forming an annulus when applied around the ostomy bag opening or to a peristomal area of skin of a user; and
applying the composition to at least a skin-facing side of the flange extender.
