Abstract

An elongate rectilinear strip of skin barrier material is disclosed, such strip being of generally uniform triangular cross section through its length, such triangle having at least two, and preferably three, unequal sides. The strip may be cut to desired length and formed, stretched and/or molded by a user into a generally circular shape or into some other shape that extends about and follows the outline of a wound or stoma.

Claims

1. An elongate and rectilinear strip of sticky, pliant, stretchable, moisture-absorbing and skinfriendly skin barrier material having both wet and dry tack, said strip being of a general uniform cross section throughout its length;

said cross section being generally that of a triangle having at least two unequal sides.

2. The strip of claim 1 in which said cross section is that of a scalene triangle.

3. The strip of claim 1 in which said cross section is that of an oblique scalene triangle.

4. The strip of claim 2 in which said cross section is that of a right scalene triangle.

5. The strip of claim 1 in which said cross section is that of an isosceles triangle.

6. The strip of claim 1 in which said strip has at least one rounded corner when viewed in cross section.

7. The strip of claims 1, 2, 3, 4, 5 or 6 in which at least one of said sides is flat.

8. The strip of claims 1, 2, 3, 4, 5 or 6 in which at least one of said sides is concave when said strip is viewed in cross section.

9. The strip of claims 1, 2, 3, 4, 5 or 6 in which at least one of said sides is convex when said strip is viewed in cross section.

10. The strip of claims 1, 2, 3, 4, 5 or 6 in which at least one of said sides has portions that are alternately concave and convex when said strip is viewed in cross section.

11. The strip of claim 1 in which said skin barrier material has a continuous phase of an elastomeric adhesive in which a discontinuous phase of hydrocolloid particles is dispersed.

12. The strip of claim 1 in which said skin barrier material is an adhesive hydrogel.

13. A method of using an elongate and rectilinear strip of sticky, pliant, stretchable, moisture-absorbing skin barrier material having generally uniform cross section throughout its length with said cross section being generally that of a triangle having at least two unequal sides, comprising the steps of orienting said strip so that it will project a selected distance from a skin or wound surface when one of said sides is adhered to said surface, and thereafter adhering a wafer having a layer of adhesive skin barrier material to said surface, with said oriented triangular strip interposed between said surface and said skin barrier layer of said wafer.

14. The method of claim 13 in which said skin barrier material of said strip has a continuous phase of an elastomeric adhesive in which a discontinuous phase of hydrocolloid particles is dispersed.

15. The method of claim 13 in which said skin barrier material of said strip is an adhesive hydrogel.

16. The method of claims 13, 14 or 15 in which said cross section of said strip is that of a scalene triangle.

17. The method of claims 13, 14 or 15 in which said cross section of said strip is that of an oblique scalene triangle.

18. The method of claims 13, 14 or 15 in which said cross section of said strip is that of an isosceles triangle.
