Abstract
An adhesive for moist tissue is formulated including a silicone elastomer, a crosslinked polyacrylic acid polymer and a sodium polyacrylate based superabsorbent polymer. The adhesive adheres well to moist tissue, such as a mucosal skin surface. An ostomy skin barrier including a stoma seal made using the adhesive is also disclosed.
Claims22
An adhesive composition for moist tissue comprising:
- about 80 wt. % to about 98 wt. % of a two-part addition curing silicone composition;
- and
- about 2 wt. % to about 20 wt. % of at least one hydrophilic component;
- wherein the adhesive composition is cured to form a viscoelastic adhesive that adheres to a moist mucocutaneous tissue and a mucosal tissue.
1 more element
An ostomy skin barrier comprising:
- a faceplate;
- a first inlet opening defined in the faceplate;
- a stoma seal provided in the first inlet opening, the stoma seal having a ring-like shape body including a second inlet opening configured to receive a stoma;
- a first adhesive layer provided on the faceplate;
- and
- a second adhesive layer provided on the faceplate surrounding the stoma seal;
- wherein each of the stoma seal, the first adhesive, and the second adhesive is formed from a different adhesive formulation.
4 more elements
An ostomy skin barrier comprising:
- a faceplate including an opening defined by an inner periphery of the faceplate;
- a first adhesive layer provided on a body side surface of the faceplate, wherein the first adhesive layer has an inner periphery that substantially lines up with the inner periphery of the faceplate;
- a backing layer having a ring-like shape provided on an inner peripheral portion of the first adhesive, such that an outer peripheral portion of the first adhesive is exposed for attachment to a user, wherein an inner diameter of the backing layer is less than inner diameters of the faceplate and the first adhesive layer, such that an inner peripheral portion of the backing layer extends beyond the inner peripheries of the faceplate and the first adhesive layer;
- a second adhesive layer having a ring-like shape provided on an outer peripheral portion of the backing layer, such that the outer peripheral portion of the backing layer is secured between the first adhesive layer and the second adhesive layer, wherein the second adhesive layer includes an opening defined by an inner periphery of the second adhesive;
- and
- a stoma seal provided in the opening of the second adhesive layer and attached to an inner peripheral portion of the backing layer, the stoma seal having a ring-like shape body including an inlet opening configured to receive a stoma.
