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.
