Abstract: A method for treating an individual to prevent the occurrence of pressure ulcers and facilitate the healing of previously existing pressure ulcers. In accordance with the present invention, a responsible individual must first determine which linens will contact pressure points on the individual as the individual lies upon a support surface. Once the appropriate linens are determined, they are prepared by cleaning the linens in ozonated wash water to limit chemical residuals and maintain neutral pH levels on the linens, wherein the linens exhibiting no chemical residuals and neutral pH cause no chemical reaction with the skin of the individual. Finally, the linens are placed into use so that they contact the skin of the individual at pressure points.

Abstract: A method and apparatus of washing laundry using a reduce amount of, or without the use of, hot water and detergents using a closed-loop or open-loop ozonated wash water system wherein wash water maintained in a contact tank is ozonated by an ozone generator prior to use in the washing machine. The oxygen and/or dried air used in the ozone generator to generate the ozone is concentrated by an oxygen concentrator before being fed into the generator. The system includes a venturi injector for entraining ozone into the water in the storage and contact tanks. The system also includes the use of contact extenders, static mixers and flow restriction fittings. The spent wash water may be collected, filtered and reused, thereby eliminating waste water disposal problems, resulting in considerable water and energy savings.
