Abstract

A collecting bag for human body wastes having a barrier film ( 20 a, 20 b ) covered by a comfort layer ( 15 ) attached to the barrier film in an attachment zone wherein the comfort layer is a textile material that is attached to said barrier film in one or more zones of attachment such that not all of the fiber filaments of the textile material in the attachment zone(s) are embedded in the barrier film material.

First claim

The invention claimed is:

1. A bag for collecting human body effluents comprising two opposing layers of a barrier film material sealingly joined to each other along a portion of an outer periphery of the opposing layers of the barrier film material, an external surface of at least one of the barrier film material layers covered by a comfort layer, wherein the comfort layer is a textile material having a number of threads, each of the threads comprising a plurality of fiber filaments, and wherein the textile material is one of a woven textile material and a knitted textile material that is attached to the barrier film material in an attachment zone along the portion of an outer periphery of the opposing layers of the barrier film material such that less than an entirety of the fiber filaments of the textile material in the attachment zone are embedded in the barrier film material.

2. The collecting bag according to claim 1 , wherein a peel strength between the comfort layer and the barrier film layer is above 5 N/12.5 mm width in the attachment zone.

3. The collecting bag according to claim 1 , wherein any fiber filaments in the attachment zone that are not embedded in the barrier film layer material provide a first portion of an external surface of the comfort layer having tactile characteristics identical to tactile characteristics in a second portion of the external surface of the comfort layer, the second portion located outside the attachment zone.

4. The collecting bag according to claim 1 , wherein any fiber filaments in the attachment zone that are not embedded in the barrier film layer material provide a first portion of an external surface of the comfort layer having visual characteristics identical to visual characteristics in a second portion of the external surface of the comfort layer, the second portion located outside the attachment zone.

5. The collecting bag according to claim 1 , wherein the textile material is a knitted material.

6. The collecting bag according to claim 1 , wherein the textile material is a woven material.

7. The collecting bag according to claim 1 , wherein the textile material is made of synthetic fibers.

8. The collecting bag according to claim 7 , wherein the synthetic fibers are polyester fibers.

9. The collecting bag according to claim 6 , wherein a weight of the textile material is in the range of 40-100 g/m2.

10. The collecting bag according to claim 6 , wherein a yarn number is in the range of 50 to 120 dtex.

11. The collecting bag according to claim 6 , wherein a thread density is in the range of 30-50 threads/cm.

12. The collecting bag according to claim 6 , wherein a number of filaments per thread is in the range of 30-150 filaments/thread.

13. The collecting bag according to claim 1 , wherein a thickness of the textile material is in the range of 100-1000 μm.

14. The collecting bag according to claim 1 , wherein a thickness of the barrier film is in the range of 60-300 μm.

15. An ostomy device comprising:
an adhesive base plate configured to be attached to a peristomal skin surface of a user, the adhesive base plate having a through-going hole defined around a first central axis of the through-going hole; and
a bag adapted for collecting stomal effluents, the bag comprising:
first and second barrier film material layers defining a joint outer periphery and connected to each other along a portion of the joint outer periphery, the first barrier film material layer including an inlet opening defined around a second central axis of the inlet opening aligned with the first central axis of the through-going hole of the base plate; and
a textile material layer covering an external surface of at least one of the first and second barrier film material layers, the textile material layer having a number of threads each comprising a plurality of fiber filaments;

wherein, the textile material layer is welded to the at least one of the first and second barrier film material layers in an attachment zone along the joint outer periphery so that less than 75% of the fiber filaments of a thread of the textile material layer are embedded in the barrier film material layer in the attachment zone along the joint outer periphery;
wherein the textile material has an increased wear strength compared to a nonwoven comfort layer as measured by resistance to pilling evaluated according to test standard DS/EN ISO 12945-2:2000.

16. An ostomy device comprising:
an adhesive base plate configured to be attached to a peristomal skin surface of a user, the adhesive base plate having a through-going hole defined around a first central axis of the through-going hole; and
a bag adapted for collecting stomal effluents, the bag comprising:
first and second barrier film material layers defining a joint outer periphery and connected to each other along a portion of the joint outer periphery, the first barrier film material layer including an inlet opening defined around a second central axis of the inlet opening aligned with the first central axis of the through-going hole of the base plate; and
a textile material layer covering an external surface of at least one of the first and second barrier film material layers, the textile material layer having a number of threads each comprising a plurality of fiber filaments;

wherein, the textile material layer is attached to the at least one of the first and second barrier film material layers along a welded attachment zone at the joint outer periphery, and less than an entirety of the fiber filaments of the textile material layer are embedded in the barrier film material layer such that a peel strength between the textile material layer and the barrier film material layer is above 5 N/12.5 mm width in the welded attachment zone at the joint outer periphery.

17. The collecting bag according to claim 1 , wherein at least some of the fiber filaments of the textile material in the attachment zone are embedded in the barrier film material.

18. The ostomy device according to claim 15 , wherein at least some of the fiber filaments of the textile material in the attachment zone are embedded in the barrier film material.

19. The ostomy device according to claim 16 , wherein at least some of the fiber filaments of the textile material in the welded attachment zone at the joint outer periphery are embedded in the barrier film material.

20. The collecting bag according to claim 1 , wherein the textile material is attached to the barrier film material in the attachment zone along the portion of the outer periphery of the opposing layers of the barrier film material with a heat lamination process in which the barrier film material is melted and at least partly flows into the textile material such that less than an entirety of the fiber filaments of the textile material in the attachment zone are embedded in the barrier film material.

21. The collecting bag according to claim 1 , wherein the textile material provides the bag with a resistance against failure caused by tear forces in the attachment zone that is at least a factor of 2 greater than a resistance against failure caused by tear forces for a bag having a nonwoven comfort layer.

22. The collecting bag according to claim 1 , wherein the textile material has an increased wear strength compared to a nonwoven comfort layer as measured by resistance to pilling evaluated according to test standard DS/EN ISO 12945-2:2000.

23. The collecting bag according to claim 1 , wh
