OSTOMY APPLIANCES WITH SULFONATED POLYMERS

1 . An ostomy appliance comprising a body side component, a biocompatible pressure sensitive adhesive component for attaching the said bodyside component to the peristomal area and/or stoma, wherein the biocompatible pressure sensitive adhesive component includes at least one polymer with sulfonated functional group.

2 . The ostomy appliance according to claim 1 , wherein the sulfonated group is 5-80% of the total polymer.

3 . The ostomy appliance according to claim 1 , wherein the polymer with sulfonated functional group is selected from a group consisting of polyacrylates, polyalkylmethacrylates, N-alkylamino acrylates, N-alkylamino methacrylates, acrylamides, styrenic block copolymers, polyesters, polyvinyl ethers, polyvinyl esters, polyolefins, silicones, polyN-vinyllactams, polyurethanes, polyethers, polysaccharides, polypeptides, and combinations thereof, furthermore, the sulfonated functional group could be in its acid, salt, amine neutralized forms, and/or combinations thereof.

4 . The ostomy appliance according to claim 1 , wherein the biocompatible pressure sensitive adhesive component could further comprise other components such as hydrophobic polymers, hydrophilic polymers, amphiphilic polymers, tackifiers, resins, plasticizers, hydrocolloids, inorganic and organic particulate fillers, antioxidants, and combinations thereof.

5 . An ostomy appliance comprising a body side component, and a separate biocompatible pressure sensitive adhesive component to coat the body side component and/or the peristomal area and stoma to secure the appliance to the peristomal area and/or stoma.

6 . An ostomy appliance having an internal and/or external portion to the stoma and a biocompatible pressure sensitive adhesive component includes a composition coating the portion of the appliance for adhering said coated portion at least to the stoma and/or the peristomal area.

7 . An ostomy appliance comprising a body side component, a biocompatible pressure sensitive adhesive component for attaching the said bodyside component to the peristomal area and/or stoma, wherein the biocompatible pressure sensitive adhesive component includes at least one polymer with sulfonated functional group, wherein the bodyside component includes a body waste collector component.

8 . The ostomy appliance according to claim 1 , wherein the biocompatible pressure sensitive adhesive component attaches under dry and wet conditions.
