Abstract: A microclimate management system for an occupant support is provided with a top layer, an intermediate air diffusion layer operatively interposable between the top layer and the occupant support, and a bottom air distribution manifold extending through the occupant support for distributing air to the intermediate air diffusion layer. There is also provided a microclimate management overlay for an occupant support having a bottom air distribution assembly mountable over the occupant support and configured for circulating air upwardly, an intermediate air diffusion layer operatively mountable above the bottom air distribution assembly for enabling air diffusion from the bottom air distribution assembly, and a top layer mountable above the intermediate air diffusion layer. There is also provided a foam support having a base foam and a seat foam insert that enables pressure redistribution to the base foam. An air pump module is also provided.

Abstract: The invention relates to a patient support apparatus, and more particularly to an ICU bed. The invention also relates to a frame assembly and to a foot extension for such patient apparatus. The invention further relates to a mattress for a patient support apparatus, such as a therapeutic mattress for an ICU bed.

Abstract: A mattress for a patient support apparatus has a cover having bottom and top surfaces, and an inflatable section disposed between the bottom and top surfaces. The inflatable section has a plurality of upper bladders in fluid communication with each other and a plurality of lower bladders in fluid communication with each other. The upper and lower bladders are selectively inflated independently from each other. The upper and lower bladders are formed by three sheets including an upper sheet, a lower sheet disposed below the upper sheet, and an intermediate sheet disposed between the upper and lower sheets. The upper sheet is fixed to the intermediate sheet to define the upper bladders between the upper sheet and the intermediate sheet. The lower sheet is fixed to the intermediate sheet to define the lower bladders between the lower sheet and the intermediate sheet. Other aspects of the mattress are also disclosed.
