Abstract
Biocompatible adhesive protective dressings, and methods of manufacturing and using the same, having properties suitable for use on moist tissues such as gingiva. The dressing may include a flexible sheet, e.g. a metal foil, with an irradiated gamma radiation sensitive adhesive on one surface. The properties of gamma sensitive adhesives are modified by exposure to gamma radiation so as to increase their adhesiveness and volume. The dressing may be applied to human or animal tissue to protect the tissue from the environment, and retain autogenous and other substances at the application site. The dressing may be used at surgical sites or wounds.
Claims30
A protective dressing comprising:
- a covering material;
- and
- a gamma irradiated, gamma radiation sensitive adhesive located on one side of said covering material, said adhesive having been irradiated with gamma radiation in an amount sufficient to alter its adhesive characteristics.
A protective dressing for protecting gingival tissue comprising a covering material and an adhesive on one side of said covering material, said adhesive being adherable to said gingival tissue, said protective dressing being configured for application thereto.
A method of protecting gingival tissue comprising applying a self-adhesive protective dressing to said gingival tissue.
A method of protecting a a surgical site in gingival tissue from the oral environment comprising:
- providing a sterile protective dressing comprising a flexible sheet-like covering material and an adhesive suitable for adhering to said gingival tissue on one side of said covering material;
- orienting said protective dressing so that said adhesive faces said gingival tissue;
- applying said protective dressing to said surgical site, wherein said protective dressing adheres to at least a portion of said gingival tissue adjacent to said surgical site.
A protective dressing for protecting gingival tissues comprising:
- metal foil;
- and
- an adhesive on one side of said metal foil comprising paraffin and gun tragacanth, wherein said adhesive has been irradiated with at least about 25 kGy of gamma radiation.
A sterile surgical package comprising at least one sterilizible protective dressing sealed in sterilizible medical packaging, said at least one sterilizible protective dressing comprising a sterilizible covering material and a gamma radiation sensitive adhesive located on one side of said covering material, said package having been sterilized with about 35 kGy of gamma radiation.
A method of providing a sterile protective adhesive dressing comprising the steps of:
- providing at least one sterilizible protective dressing sealed in sterilizible medical packaging, said at least one sterilizible protective dressing comprising a sterilizible covering material and gamma radiation sensitive adhesive on one side of said sterilizible covering material;
- and
- sterilizing said at least one sterilizible protective dressing with about 25 kGy to about 50 kGy of gamma radiation.
