ABSTRACT:
An air mattress for preventing bedridden patients' suffering from bed sores and the like is provided. A mattress assembly is provided comprising a matrix member disposed throughout its interior region for uniformly distributing air to the mattress-patient interface. This matrix member comprises a network of vertical rigid tubes and interconnected horizontal rigid tubes which are configured to uniformly distribute air to the upper mattress surface. Ambient air enters into the bottom end of this plurality of vertical tubes and is then delivered to the upper mattress surface through a plurality of tufted recess surfaces located at the top end of the plurality of vertical tubes. The matrix member is contained within an air mattress portion which is, in turn, configured to be abuttably received by a corresponding peripheral mattress portion. The air mattress portion is secured to the peripheral mattress portion by brace members. This combination of air mattress and peripheral mattress portions rests upon a like sized frame member, at a predetermined height. Maintained by a plurality of spacers, this gap enables air to flow up through and among the array of tubes that populate the matrix member. Also provided is an air cushion assembly comprising an air cushion member having a matrix member and an outer air permeable covering for preventing chafing and sores to a seated person.
