  • Patent number: 11406541
    Abstract: A wound dressing is made from a tubular inner layer and at least one outer layer disposed radially beyond the inner layer. The inner layer permits egress of fluid from weeping wounds, prevents desiccation of skin disposed beneath the inner layer, and prevents desiccation of ointment disposed between the inner layer and the skin. The at least one outer layer absorbs fluids that leak through the inner layer, protects the inner layer from outside contaminants, and prevents fluids from escaping. The at least one outer layer is affixed to the inner layer, and each of the layers is elastic in at least the radial direction. Optionally, a layer of ointment may be applied to an inner surface of the inner layer. Note that the tubular inner layer may be either pre-formed or formed at the time of application.
