Abstract

An inflatable mattress made of multiple, integrally joined cushions designed to reduce patient interface pressures, which may be used separately or as an overlay on a standard hospital bed. Each cushion and section of the mattress is formed by joining upper and lower sheets, both to form the edges of the cushions and sections and to provide a relatively flat support surface which is laterally bounded by inflatable ridges which help keep the patient from rolling or sliding off either side of the mattress. The upper and lower sheets to form the mattress are made from a water vapor permeable but waterproof material, certain sections of the upper surface of the cushions being formed of air-permeable material which serves to allow air to escape in the area where a patient lies to provide comfort and therapy for the patient. A blower for the mattress provides compressed air at separately adjustable flow rates through three separate conduits and also include a heating element for warming the air to enhance the therapeutic benefits of the mattress.
