Abstract:
An anti-decubitus pneumatic mattress adapted to replaceably overlay a conventional mattress of a bed and have a patient lie thereon, said anti-decubitus pneumatic mattress comprising:a) a main assembly having a longitudinal axis and opposing longitudinal sides, and comprising a plurality of inflatable cells, wherein said plurality of cells are divided by said longitudinal axis of said main assembly into a pair of side by side banks of cells, extending longitudinally wherein adjacent cells in each bank overlap each other to form a continuous, non-spaced surface for uniform support of the patient, and wherein each bank of said pair of side by side banks of cells is elongated, independently formed, and separately removable;b) a pair of bolsters, each of which being replaceably attached to, and extending along, a respective longitudinal side of said opposing longitudinal sides of said main assembly, and being selectively inflatable,; andc) first means for selectively inflating and deflating said plurality of cells of said main assembly and each of said pair of bolsters;d) second means for controlling the selective inflation and deflation of said plurality of cells for providing a static mode for maintaining all of said plurality of cells inflated for cushioning the patient on a static cushion of air, a lateral rotation mode for causing said patient to turn in alternative directions, and an alternating pressure mode for causing different parts of the patient to alternately rise and lower.
