Abstract

An ostomy appliance for attachment to a stoma, the ostomy appliance comprising: an adhesive wafer ( 100 ) defining a passage for receiving a stoma of a user, the adhesive wafer comprising a backing layer and a skin facing adhesive layer; and a collecting bag ( 116 ) which in use is secured to the adhesive wafer; wherein the adhesive wafer in a first adhesive zone has a first set of properties and in a second adhesive zone ( 104 ) has a second set of properties, the first zone defining three or more radially extending zones, wherein the second zone defines one or more interconnecting parts ( 110 ), each of which interconnects at least two of the radially extending zones ( 108 ).

First claim

The invention claimed is:

1. An ostomy appliance attachable around a stoma, the ostomy appliance comprising:
an adhesive wafer defining a passage for receiving the stoma, the adhesive wafer comprising:
a backing layer having a proximal side and an opposite distal side and a skin facing adhesive deposited on the proximal side of the backing layer, with the backing layer extending from an edge of the passage to an outer peripheral edge of an outer perimeter of the adhesive wafer, and the skin facing adhesive deposited on the backing layer from the edge of the passage to the outer peripheral edge of the outer perimeter of the adhesive wafer;
a collecting bag attachable to the distal side of the backing layer of the adhesive wafer;
wherein the skin facing adhesive comprises:
a first adhesive zone and
a separate second adhesive zone,
wherein the first adhesive zone comprises a central adhesive zone that surrounds the passage and three or more radial adhesive zones that are connected to and extend radially from the central adhesive zone towards the outer peripheral edge of the adhesive wafer,

wherein the second adhesive zone comprises two or more interconnecting parts that are separated from each other and each separately interconnects each of the three or more radial adhesive zones to another of the three or more radial adhesive zones,
wherein each of the interconnecting parts of the second adhesive zone extends in an arc around the passage; and
wherein at least one of the interconnecting parts of the second adhesive zone is provided as part of the skin facing adhesive provided in the outer perimeter of the adhesive wafer.

2. The ostomy appliance according to claim 1 , wherein the interconnecting part is defined between any two neighboring radially extending zones.

3. The ostomy appliance according to claim 1 , wherein a yield strength of the first adhesive zone and a yield strength of the second adhesive zone are identical.

4. The ostomy appliance according to claim 1 , wherein a yield strength of the first adhesive zone is higher than a yield strength of the second adhesive zone.

5. The ostomy appliance according to claim 1 , wherein a stiffness of the first adhesive zone is larger than a stiffness of the second adhesive zone.

6. The ostomy appliance according to claim 1 , wherein the second adhesive zone is thicker than the first adhesive zone in a direction transverse to a line extending radially from the stoma passage of the adhesive wafer.

7. The ostomy appliance according to claim 1 , wherein the first adhesive zone is thicker than the second adhesive zone in a direction transverse to a line extending radially from the stoma passage of the adhesive wafer.

8. The ostomy appliance according to claim 1 , wherein an absorption capability of the first adhesive zone is higher than an absorption capability of the second adhesive zone.

9. The ostomy appliance according to claim 1 , wherein a shape of the adhesive wafer is circular or oval.

10. The ostomy appliance according to claim 1 , wherein the three or more radial adhesive zones are spaced apart equidistantly around a circumference of the central adhesive zone.

11. The ostomy appliance according to claim 1 , wherein the central adhesive zone is circular or oval.

12. The ostomy appliance according to claim 1 , wherein each of the three or more radial adhesive zones terminates in a point located at a predetermined radial distance from a center of the passage.

13. The ostomy appliance according to claim 1 , wherein the interconnecting part extends radially from the passage.

14. The ostomy appliance according to claim 1 , wherein the interconnecting part is an annular band.

15. The ostomy appliance according to claim 1 , wherein the first and second adhesive zones combine to define a spider web configuration of the adhesive wafer.

16. The ostomy appliance according to claim 1 , wherein the second adhesive zone is located at the outer peripheral edge of the outer perimeter.

17. The ostomy appliance according to claim 1 , wherein the second adhesive zone extends a distance of at least 30% of a circumference of the outer perimeter of the adhesive wafer.

18. The ostomy appliance according to claim 1 , wherein each of the three or more radial adhesive zones has a first width measured at the central adhesive zone and a second width measured at the second adhesive zone, with the first width larger than the second width.

19. The ostomy appliance according to claim 1 , wherein the outer perimeter of the adhesive wafer, including both a backing layer outer perimeter and a second adhesive zone outer perimeter, extends radially outward from outer edges of the three or more radial adhesive zones.

20. The ostomy appliance according to claim 1 , wherein at least one of the interconnecting parts of the second adhesive zone is provided as part of adhesive zone outer perimeter of the outer perimeter of the skin facing surface of the second adhesive zone; and
a skin facing surface of the adhesive zone outer perimeter of the outer perimeter is configured to attach to skin around the stoma.

21. The ostomy appliance according to claim 1 , wherein the adhesive wafer includes a collecting bag adhesive that is deposited on the distal side of the backing layer, and further wherein the collecting bag adhesive is in a pattern different from the first adhesive zone and the separate second adhesive zone of the skin facing adhesive.

22. The ostomy appliance according to claim 1 , wherein the collecting bag includes a collecting bag adhesive that is deposited on a portion of the collecting bag, and further wherein the collecting bag adhesive is in a pattern different from the first adhesive zone and the separate second adhesive zone of the skin facing adhesive.

23. An adhesive wafer defining a passage for receiving a stoma, the adhesive wafer comprising:
a backing layer having a proximal side and an opposite distal side;
a skin facing adhesive deposited on the proximal side of the backing layer, with the backing layer extending from an edge of the passage to an outer peripheral edge of an outer perimeter of the adhesive wafer, with the skin facing adhesive deposited on the backing layer from the edge of the passage to the outer peripheral edge of the outer perimeter of the adhesive wafer;
wherein the skin facing adhesive comprises:
a first adhesive zone and
a separate second adhesive zone,
wherein the first adhesive zone comprises a central adhesive zone that surrounds the passage and three or more radial adhesive zones that are connected to and extend radially from the central adhesive zone towards the outer peripheral edge of the adhesive wafer,
wherein the second adhesive zone comprises two or more interconnecting parts that are separated from each other and each separately interconnects each of the three or more radial adhesive zones to another of the three or more radial adhesive zones,
wherein each of the interconnecting parts of the second adhesive zone extends in an arc around the passage, and
wherein at least one of the interconnecting parts of the second adhesive zone is provided as part of the skin facing adhesive provided in the outer perimeter of the adhesive wafer.
