OSTOMY DEVICES WITH MUCOADHESIVES
The present invention provides a biocompatible adhesive for securely adhering ostomy appliances simultaneously to the body and the stoma. The ostomy appliance is comprised of an adhesive component and a body waste collector component, wherein the adhesive component includes a mucoadhesive component. The mucoadhesive component comprises a polymer with functional groups that provide adhesion to skin and stoma.
1 . An ostomy appliance comprising an adhesive component for attaching the appliance to the peristomal area and/or stoma, and a body waste collector component, wherein the adhesive component includes a mucoadhesive component.
2 . The ostomy appliance according to claim 1 , wherein the mucoadhesive component comprises a polymer containing functional groups selected from a group consisting of caprolactams, glycols, amines, alderhydes, hydroxyls, maleimides, thiols, acids and their salts, iminothiolanes, thioalkylamidines, catechols, amino acids, dihydroxy substituted aromatic groups, and combinations thereof.
3 . The ostomy appliance according to claim 2 , wherein the polymer is a biocompatible polymer of synthetic or natural origin selected from a group consisting of polyacrylates, polyakylmethacrylates, polyphenylmethacrylate, polyanhydrides, styrenic block copolymers, polyamides, polyesters, polyvinyl ethers, polyvinyl esters, sulfonated polymers, polyolefins, silicones, polyvinylpyrrolidones, polyvinylacetate and its copolymers, polyvinyl acohol, polyurethanes, polyethers, copolymers of maleic anhydride, polysaccharides, polypeptides, gelatin, alginates, gums, starch, chitosan, pectin, and combinations thereof.
4 . The ostomy appliance according to claim 1 , wherein the mucoadhesive further contains other components selected from the group consisting of hydrophobic polymers, hydrophilic polymers, amphiphilic polymers, tackifiers, resins, plasticizers, hydrocolloids, inorganic and organic particulate fillers, antioxidants, and combinations thereof.
5 . The ostomy appliance according to claim 1 , wherein the mucoadhesive component is a pressure sensitive adhesive.
6 . The ostomy appliance according to claim 1 , wherein the mucoadhesive component is a non-pressure sensitive adhesive.
7 . An ostomy appliance comprising an adhesive component, a body waste collector component, and a separate mucoadhesive component to coat the adhesive component and/or the peristomal area and stoma to secure the appliance to the peristomal area and stoma.
8 . The ostomy appliance according to claim 7 , wherein the mucoadhesive component comprises a polymer containing functional groups selected from a group consisting of thiols, acids and their salts, iminothiolanes, thioalkylamidines, catechols, amino acids, dihydroxy substituted aromatic groups, and combinations thereof.
9 . The ostomy appliance according to claim 7 , wherein the mucoadhesive component is a pressure sensitive adhesive.
10 . The ostomy appliance according to claim 7 , wherein the mucoadhesive component is a non-pressure sensitive adhesive.
11 . An ostomy appliance having an internal and/or external portion to the stoma and a mucoadhesive component coating the portion of the appliance for adhering said coated portion at least to the stoma and/or the persitomal area.
