Abstract

The present invention relates to a disposable excreta management device comprising a composite body adhesive structure for releasable attachment of said device to the body of a wearer, said structure comprising a substrate and a layer of an adhesive material coated onto said substrate. The layer of adhesive material comprises a pattern of less adhesive areas where the adhesive is inactivated or covered by a second material having a lower adhesion on skin compared to said adhesive material. The device is easy to handle, not painful to remove, easy to reposition, and leaves no residues on skin.

Claims

1. A disposable excreta management device comprising means for excreta collection and storage, and a composite body adhesive structure for releasable attachment of said device to the body of a wearer, said structure comprising:

a substrate

a layer of an adhesive material coated onto said substrate

said device being characterized in that said layer of adhesive material comprises a pattern of less adhesive areas where the adhesive is inactivated or covered by a second material having a lower adhesion on skin compared to said adhesive material.

2. A disposable excreta management device according to claim 1 wherein said pattern of less adhesive areas represents from 10 to 70% of the total surface area of said layer of adhesive material.

3. A disposable excreta management device according to claim 1 wherein said second material is a plastic or fibrous or powder material.

4. A disposable excreta management device according to claim 1 wherein said pattern is a continuous pattern of interconnected less adhesive areas.

5. A disposable excreta management device according to claim 4 wherein said pattern is a regular pattern.

6. A disposable excreta management device according to claim 5 wherein said regular pattern is a net pattern.

7. A disposable excreta management device according to claim 4 wherein said pattern defines a plurality of spaced apart adhesive areas, said spaced apart adhesive areas being characterized in that their average surface area is from 0.5 to 400 mm².

8. A disposable excreta management device according to claim 7, wherein immediately adjacent spaced apart adhesive areas are spaced apart from each other by a distance of not less than 0.5 mm.

9. A disposable excreta management device according to claim 1 wherein said pattern comprises a plurality of spaced apart discrete less adhesive areas.

10. A disposable excreta management device according to claim 9 wherein said plurality of spaced apart discrete less adhesive areas is in the shape of dots or stripes.

11. A disposable excreta management device according to claim 9 wherein said spaced apart less adhesive areas are characterized in that their average surface area is from 0.5 to 400 mm².

12. A disposable excreta management device according to claim 3 wherein said plastic material comprises a perforated plastic

13. A disposable excreta management device according to claim 3 wherein said fibrous material comprises a nonwoven layer or a stretchable net.

14. A disposable excreta management device according to claim 1 wherein said second material is substantially non adhesive on skin.

15. A disposable excreta management device according to claim 1 wherein said means for excreta collection and storage comprise a bag, said bag having an aperture, said aperture being surrounded by said composite adhesive structure for releasable attachment of said device to the uro-genital area of a wearer.

16. A disposable excreta management device according to claim 1 wherein said composite adhesive structure has an external perimeter and an internal perimeter, said internal perimeter substantially corresponding to said aperture in said bag and wherein said pattern of less adhesive areas comprises an area along said external perimeter.

17. A disposable excreta management device according to claim 16 wherein said pattern of less adhesive areas also comprises an area along said internal perimeter.

18. A disposable excreta management device according to claim 16, wherein said layer of adhesive material is thinner along said external perimeter of said composite adhesive structure than in the remaining portions of said layer of adhesive material.

19. A disposable excreta management device according to claim 16, wherein at least a portion of said layer of adhesive material is thinner at the interior of said composite adhesive structure than in the remaining portions of said layer of adhesive material.
