Abstract
An air distribution device with a plurality of sheets is provided to prevent and treat decubitus ulcers. Air from an air source is provided between sheets of the coverlet which are air tight except for a plurality of very tiny apertures that are provided in the top sheet. The device is used between a support surface such as an alternating pressure mattress and a patient. The air escaping from the tiny apertures circulates around the patient to remove excess moisture from the patient's skin and wounds. The top sheet of the coverlet is made of a low friction nylon with an undercoating of a waterproof yet vapor permeable polyurethane. The top sheet has a plurality of apertures punched through the material. The central sheet is made out of the identical material of the top sheet, except there are no tiny apertures. The central sheet is a diffuser sheet, in that no air flow passes through it, but it spreads the air throughout the air tight portion of the device, allowing air to escape through the apertures in the top sheet directly to the patient. The bottom sheet is preferably a quilted synthetic material such as DACRON.TM. to provide a space for the vapor molecules, once they have passed through the coated nylon, to travel into and disperse.
