ABSTRACT:
A device is provided for the topical localized administration of zinc to tissue. The device comprises a central layer of absorbent material, with the central layer containing a mixture of particulate superabsorbent and zinc chloride that is sandwiched between a first and second layer of perforated polymeric film that is sealed at the edges. The device is activated by exposure to aqueous media prior to application to tissue. The quantity of zinc chloride contained in the device is varied according to the intended use. High levels of zinc chloride are used to form more concentrated solutions or gels for fixation of necrotic, gangrenous or cancerous tissue to facilitate excision or amputation while lower levels are used for more dilute solutions or gels to promote formation of granulation tissue and healing of lesions in non-necrotic tissue. The device is wrapped on the site to be treated or attached by adhesive means and is kept in place for a period appropriate to the intended use.
