SYSTEM AND METHOD FOR MAINTAINING AIR INFLATABLE MATTRESS CONFIGURATION

A system and method for maintaining an air inflation mattress configuration sufficient for patient support and comfort. Infrared illumination levels are measured within individual or groups of inflated mattress chambers. A staggered approach to illumination monitoring of chambers or sections to eliminate crosstalk between the infrared sensors is carried out. Distributed microprocessor controllers established in a network configuration utilizing controller network protocols reduces the wiring and connections necessary for the assembled system. Various mattress cushion construction techniques, such as sewing and or RF welding methods, are used for the creation of individual chambers utilizing specific types of IR translucent, transparent or reflective materials. The construction of the cushions and bladders in the system includes the use of various types of fabrics with low to high air loss qualities as required. The overall mattress assembly, including the control systems and the methodologies associated with such control systems, provide a unique approach to the maintenance of a consistently comfortable patient support surface. The use of a handheld unit for both programming the system and downloading information about the operation of the system is also anticipated. The specific cushion construction designs associated with the head, body, and foot cushion components of the mattress are tailored to operate specifically with the control capabilities (sensors and air flow regulators) of the invention. Un sistema y metodo para mantener la configuracion suficiente de colchones inflados con aire para el soporte y confort de un paciente. Los niveles de iluminacion infrarroja se miden dentro de camaras de colchones inflados individuales o en grupos. Se lleva a cabo un procedimiento escalonado para monitorear la iluminacion de las camaras o secciones para eliminar la interferencia entre los detectores infrarrojos. Los controladores distribuidos del microprocesador establecidos en una configuracion en red que utilizan protocolos de la red de controladores reducen el cableado y conexiones necesarias para el sistema ensamblado. Se utilizan varias tecnicas de construccion del amortiguamiento del colchon, tales como metodos de cosido y o soldeo por RF, para la creacion de camaras individuales utilizando tipos especificos de materiales translucidos, transparentes o reflejantes de IR. La construccion del amortiguamiento y las camaras de aire en el sistema incluye el uso
