Abstract
An ostomy wafer includes a stoma receiving hole formed through an adhesive layer and a backing layer of the ostomy wafer and has a central area formed as a continuous band of material around an entire perimeter of the stoma receiving hole. An outer periphery of the wafer is formed by a plurality of petals connected to and extending away from the central area, and a plurality of bridges is provided formed between adjacent petals of the plurality of petals. A thickness of the adhesive layer measured within one of the plurality of bridges is greater than a thickness of the adhesive layer measured within one of the plurality of petals.
Claims13
An ostomy wafer comprising:
- a stoma receiving hole formed through an adhesive layer and a backing layer of the ostomy wafer and a central area formed as a continuous band of material around an entire perimeter of the stoma receiving hole;
- a plurality of petals connected to and extending away from the central area, with each of the plurality of petals radially extending from the central area to an end that is formed as a convex apex;
- and
- a plurality of bridges, each of the plurality of bridges formed between adjacent petals of the plurality of petals such that a first portion of an outer periphery of the wafer is concave and formed by one of the plurality of bridges;
- wherein a thickness of the adhesive layer measured within one of the plurality of bridges is greater than a thickness of the adhesive layer measured within one of the plurality of petals and each of the plurality of bridges has an embossed pattern of lines formed in a surface of each of the plurality of bridges, wherein a distance between adjacent lines in the embossed pattern of lines increases in a direction from a location within each of the plurality of bridges toward one of the adjacent petals of the plurality of petals.
An ostomy wafer comprising:
- an adhesive layer applied to a backing layer, with a stoma receiving hole formed through the adhesive layer and the backing layer, with a central area of the ostomy wafer formed as a continuous band of material around an entire perimeter of the stoma receiving hole;
- a first petal connected to and extending in a radial direction away from the central area, a second petal connected to and extending in a radial direction away from the central area, and a bridge connected between the first petal and the second petal, with each of the first petal and the second petal terminating at a convex apex and the bridge has an outermost radial edge connected between the first petal and the second petal that is concave;
- and
- an embossed pattern of lines formed in the backing layer of the bridge, with the embossed pattern of lines formed into a portion of the adhesive layer;
- wherein a thickness of the adhesive layer measured in the bridge is greater than a thickness of the adhesive layer measured within one of the first petal and the second petal;
- wherein a distance between adjacent lines in the embossed pattern of lines, measured along the outermost radial edge, increases in a direction from a location within the bridge toward the first petal.
