Abstract
Water soluble hydrogels of alkali metal alginate and glycerine have been found to be excellent wound dressings. The gels dry to an adherent, non-toxic pliable protective film which can be removed by water-washing when desired. The gels are also compatible with medicaments and hence can serve as vehicles or carriers for medicament application to wounds as well as a protective cover.
Claims13
A gel composition, having use as a wound dressing, comprising a water-soluble hydrogel consisting essentially of about 0.5 to 3% by weight of alkali metal alginate, about 8 to 12% by weight glycerine and about 82 to 90% by weight water wherein said hydrogel has a pH in the range of 6.8 to 7.2 and which upon drying forms a flexible, stretchable, transparent water-soluble protective film, nontoxic and adherent to a wound surface to which said gel composition is applied for protection.
A method for protecting wounds which comprises applying over a wound surface a coating of a gel composition comprising a water-soluble hydrogel consisting essentially of about 0.5 to 3% by weight alkali metal alginate, about 8 to 12% by weight glycerine and about 82 to 90% by weight water wherein said hydrogel has a pH in the range of 6.8 to 7.2 and allowing the coating to dry to a water-soluble, flexible, stretchable, transparent, protective film, non-toxic and adherent to said wound surface.
