A two-mode therapeutic mattress system is provided, including a non- powered air mattress, a pressure dispersion cushion, and a selectively operable air diffusion coverlet in a common modular assembly for improved medical management of skin care. The non-powered air mattress includes longitudinal air cylinders providing a static air support system inflated to predetermine d pressure. The longitudinal air cylinders are in pressure communication with elasticized reservoirs, in that the air level in the elasticized reservoirs dynamically reacts to changes in pressure in the longitudinal air cylinders, for example upon receipt of a patient upon the mattress system. The pressure dispersion cushi on facilitates pressure relief with a number of lateral and longitudinal cuts resulting in a plurality of separate upright support cells, the size and construction of which may vary over the surface of the pressure dispersion cushion so as to provid e selective support characteristics. The air diffusion coverlet contains a plurality of air pockets. The air diffusion coverlet operates in two modes: a "therapy mode" such that compressed air from an air compressor is pumped to the air diffusi on coverlet, and an "off' mode in which the air pockets collapse to provide a suitable and relatively smooth bedding component to the therapeutic mattress system. The non-powered air mattress, pressure dispersion cushion, and selective ly operable air diffusion coverlet cooperate to provide a single product that addresses localized pressure, maceration, shear stress, and dynamic changes in a patient's condition during the course of time. |
