Abstract

A bandage strip and method for application and removal of the bandage is described. The bandage is tappered to induce the user to remove the bandage from the tappered end versus a wide end according to a particular direction. The bandage also contains a novel matrix which assists in diminishing the pain and skin maceration associated with removal of adhesive bandages.

Claims

1. An adhesive bandage for use in covering and protecting a site of injury on a subject, the bandage having an adhesive surface portion and a non-adhesive wound covering portion wherein the adhesive surface portion is overlayed with a non-adhesive matrix.

2. A bandage according to claim 1 having a longitudinal axis with a first end and second end, the first end being narrower in width than the second end, the bandage generally widening overall from the first end to the second end, the first end marked so as to encourage the patient to remove the bandage commencing with pulling the first end toward the second end.

3. A bandage according to claim 2, where the first end tip is colored green.

4. The bandage of claim 1, wherein the matrix is a configuration selected from the group consisting of web, spiral honeycomb and finger print.

5. The bandage of claim 4, wherein adhesive is on the matrix and the portion of the bandage on which the matrix is overlayed does not have adhesive.

6. The bandage of claim 4 wherein the site of injury is on a part of the subject which contains body hair.

7. An adhesive bandage for use in covering and protecting a site of injury, wherein the bandage contains a first permeable layer, a second layer of adhesive, a protective gauze material in the middle of the bandage creating regions of adhesion, and a third layer comprising a matrix of non-adhesive material positioned over the adhesive regions, the matrix creating areas of adhesion and non-adhesion within the regions and positioned on the adhesive regions so as to create a pattern of adhesive and non-adhesive areas such that the pattern achieves a distribution of differently sized adhesive areas wherein there is a high density of small areas of adhesion in the centre of the adhesive regions and fewer numbers of larger areas of adhesion at the perimeter of the adhesive portion, the degree of adhesion being lower toward the centre in comparison with the perimeter of the bandage, said adhesive areas increasing in size from the centre of the adhesive portion to the perimeter of the adhesive portion.

8. A bandage according to claim 7, wherein the matrix is a spiral with a centre and spokes emanating from the centre of the spiral.

9. A bandage according to claim 7, wherein the spirals are located at a distance of not greater than 2 mm at the perimeter of the bandage.

10. A bandage according to claim 7, wherein the spirals are located at a distance of not greater than 1.5 mm at the perimeter of the bandage.

11. A bandage according to claim 7, wherein the matrix is a configuration selected from the group consisting of a web finger print and honeycomb.

12. A bandage according to claim 7, wherein the matrix is adhesive and the adhesive portion is not adhesive.

13. The bandage of claim 10 or 11 having a longitudinal axis with a narrow end and an end wider than the narrow end.

14. The bandage of claim 7 where the site is on a part of the subject containing hair.

15. A method for applying onto and removing from a skin surface, an adhesive bandage having a longitudinal axis greater than its width, for use in reducing the pain and maceration of skin surface associated with removal of such adhesive bandage, said method comprising first identifying a linear pattern of hair growth, where hair ends provide a first position and hair roots are in a second position with hair moving from root to hair end so as to result overall in said linear pattern;

placing the bandage on the skin such that the longitudinal axis is parallel to the linear pattern of hair growth; and

when appropriate, removing said bandage by grasping the end of said bandage placed at the root end of the pattern and pulling toward the end at the hair end of said pattern.

16. The method of claim 15, wherein the bandage has a tappered end placed at the root end and a wider end placed at the hair end.

17. The method of claim 16, wherein the bandage has a non-adhesive matrix overlaying the adhesive portion.

18. The method of claim 17, wherein the matrix has a design selected from the group consisting of web, spiral honeycomb and finger print.

19. The method of claim 15 wherein the site is on a part of the subject which contains hair.

20. The method of claim 15 wherein removing the bandage is achieved by peeled it off.
