Abstract:
A kit for preparing a flexible intra-oral bandage, the kit comprising a water-permeable envelope, the envelope being formed of a non-woven, water-porous fabric, a powder/fiber mixture contained within the envelope, the powder/fiber mixture comprising a dry, particulate water-soluble powder, comprising a soluble alginate salt admixed with a soluble reactor salt, and water-wettable fibers, the reactor salt and alginate being present in relative quantities sufficient to produce, when admixed with water, a water-insoluble cross-linked alginate salt, said fibers carrying a static electricity charge, the thickness of the fiber being an order of magnitude smaller than the length of the fiber, and the powder carrying a static electricity charge opposite to that of the fibers, and having a particle size smaller than that of the fibers; the charged powder particles being distributed on and adhering to the oppositely charged fibers; said porous envelope being so arranged to allow an aqueous liquid to pass through to and to wet said alginate-salt powder/fiber mixture when the envelope is immersed in water, and the powder/fiber mixture being so admixed that when wetted with water it is converted to a moldable, tacky fiber-reinforced gel, suitable for use as an intra-oral bandage.
