    摘要: A water vapor permeable dressing, such as a surgical dressing, is constructed of a thin elastomeric transparent film which is protected by a layer of non-woven fabric, such as a material of elastomeric filaments. The fabric is sufficiently thin, elastic and fluffy to absorb stress of abrasive objects so as to protect the underlying film. Both the film and the protective fabric are sufficiently thin and compliant to allow the dressing to conform to the contours of the human body. Adhesive used in the dressing, for securing the film to a person's skin, as well as for securing the fabric to the film, are permeable to water vapor. The film and the adhesives are impermeable to liquid water, thereby to provide an effective shield for a wound against infection by outside bacteria. A method of administering a topical reagent to a patient is disclosed. The method involves (1) imprinting a topical reagent upon the surface of a release sheet, (2) applying adhesive to a conformable elastic film, (3) joining the imprinted release sheet surface and the adhesive layer surface together, (4) separating the release sheet and film and (5) applying the film to a patient so that the topical reagent is in direct contact with the patient's skin.
