Abstract
Abstract An attachment assembly is disclosed for attaching an article such as a wound cover or a prosthesis to human skin. The article attached may be, for example, a cover or dressing over a wound or a fistula or other lesion, it may be an eye patch or a breast prosthesis for use after masectomy or it may be a pouch to cover the genital region. The attachment assembly comprises a body-attachable pad of skin-compatible adhesive material and a series of double-sided adhesive layers thereon, which layers are constructed and arranged to be manually peeled off one-by-one when desired in order to expose a fresh adhesive surface to which the article is then attached.
