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.

- 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.

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. - View Dependent Claims (16, 17, 18, 19, 20)
