Abstract

Disclosed is an adaptable ostomy base plate (10) comprising a flexible top film (8), at least one elastic adhesive (6) disposed on the top film and at least one release liner (9), the base plate having at least a first convex section (1) that can be inverted to a concave section to be used for especially demanding skin surface conditions, such as in ostomists suffering from hernia.

Claims

1. An adaptable ostomy base plate comprising a flexible top film and having at least a first and a second section, at least a first elastic skin-friendly adhesive on a proximal surface of said flexible top film, a stoma-receiving through-going hole in said first section, said first section being adjacent to and extending radially from said through-going hole and said second section surrounding said first section, and one or more release liners, wherein at least said first section has a first substantially convex shape for initial engagement with a peristomal skin surface, at least said first section being invertible to a first substantially concave shape to fittingly engage said first section to a topography of the peristomal skin surface for permanent engagement thereto.

2. An adaptable ostomy base plate according to claim 1, wherein said second section has a second substantially convex shape being invertible to a second substantially concave shape.

3. An adaptable ostomy base plate according to claim 1, wherein said second section has a second substantially concave shape.

4. An adaptable ostomy base plate according to any one of claims 1-3, further comprising a substantially planar surface zone between said first and second sections.

5. An adaptable ostomy base plate according to claim 4, wherein said substantially planar surface zone distally accommodates first coupling means for coupling engagement with corresponding coupling means on a collecting bag for human body wastes.

6. An adaptable ostomy base plate according to any one of claims 1-4, wherein said first or second section distally comprises first coupling means for engagement with corresponding coupling means on a collecting bag for human body wastes.

7. An adaptable ostomy base plate according to any one of the preceding claims, comprising a second skin-friendly adhesive on said proximal surface of said flexible top film.

8. An adaptable ostomy base plate according to claim 7, wherein the first elastic skin-friendly adhesive is provided on the first section and the second skin-friendly adhesive is provided on the second section.

9. An adaptable ostomy base plate according to claim 7 or 8, wherein the second skin-friendly adhesive is elastic.

10. An adaptable ostomy base plate according to any one of claims 7-9, wherein said second elastic skin-friendly adhesive comprises a polar plasticizing oil or a combination of polar plasticizing oils in the content of above 10% (w/w) of the final second adhesive, and at least one polar polyethylene copolymer, wherein the content of the polyethylene copolymer is 10-50% (w/w) of the final second adhesive, the polyethylene copolymer has a melt flow index below 2 g/10 min (190°

C./21.1N).

11. An adaptable ostomy base plate according to any one of claims 7-10, wherein the thickness of the second elastic skin-friendly adhesive is 300-700μ

.

12. An adaptable ostomy base plate according to any one of the preceding claims, wherein at least said second section further comprises a reinforcing element.

13. An adaptable ostomy base plate according to any one of the preceding claims, wherein the flexible top film is a three-layer laminate.

14. An adaptable ostomy base plate according to claim 13, wherein the flexible top film is between 400-700% elongatable before failure.

15. An adaptable ostomy base plate comprising a flexible top film and having at least a first and a second section, at least a first elastic skin-friendly adhesive on a proximal surface of said flexible top film, a stoma-receiving through-going hole in said first section, said first section being adjacent to and extending radially from said through-going hole and said second section surrounding said first section, and one or more release liners, wherein at least said first section can be inverted to a first substantially concave shape.

16. An adaptable ostomy base plate according to claim 15, wherein said second section has a second substantially convex shape that can be inverted to a second substantially concave shape.

17. An adaptable ostomy base plate according to claim 15, wherein said second section has a second substantially concave shape.

18. An adaptable ostomy base plate according to any one of claims 15-17, further comprising a substantially planar surface zone between said first and second sections.

19. An adaptable ostomy base plate according to claim 18, wherein said substantially planar surface zone distally accommodates first coupling means for coupling engagement with corresponding coupling means on a collecting bag for human body wastes.

20. An adaptable ostomy base plate according to any one of claims 15-19, wherein said first or second section distally comprises first coupling means for engagement with corresponding coupling means on a collecting bag for human body wastes.

21. An adaptable ostomy base plate according to any one of claims 15-20, comprising a second skin-friendly adhesive on said proximal surface of said flexible top film.

22. An adaptable ostomy base plate according to claim 21, wherein the first elastic skin-friendly adhesive is provided on the first section and the second skin-friendly adhesive is provided on the second section.

23. An adaptable ostomy base plate according to claim 21 or 22, wherein the second skin-friendly adhesive is elastic.

24. An adaptable ostomy base plate according to any one of claims 21-23, wherein said second elastic skin-friendly adhesive comprises a polar plasticizing oil or a combination of polar plasticizing oils in the content of above 10% (w/w) of the final second adhesive, and at least one polar polyethylene copolymer, wherein the content of the polyethylene copolymer is 10-50% (w/w) of the final second adhesive, the polyethylene copolymer has a melt flow index below 2 g/10 min (190°

C./21.1N).

25. An adaptable ostomy base plate according to any one of claims 21-24, wherein the thickness of the second elastic skin-friendly adhesive is 300-700μ

.

26. An adaptable ostomy base plate according to any one of claims 15-25, wherein at least said second section further comprises a reinforcing element.

27. An adaptable ostomy base plate according to any one of claims 15-26, wherein the flexible top film is a three-layer laminate.
