A self-contained active thermal regulating device includes a flexible, deformable outer membrane; a liquid saturated foam core contained therein having a dimension substantially coincident with the outer membrane wherein the liquid is at least partially circulable throughout the foam core; and, a phase change material being in intimate contact with the circulable liquid. The circulation of the liquid is effective to transfer heat between the flexible, deformable outer membrane and the phase change material to cool (or heat) the device without use of external power and the saturated foam core in cooperation with the sealable flexible membrane providing a substantially uniform, thermal regulating medium and structural support such that the device is readily, uniformly deformable when a load is applied thereto.

Adjustable mattress assemblies are described in which a mattress incorporates regions where additional pressure reduction is adjustable via pliable fluid bladders filled with a gas or fluid. Such areas of the mattress where additional pressure reduction is desired may include regions of the mattress which support areas of the body which may be particularly susceptible to pressure ulcers such as the heels, sacral regions, etc.

Implementations described and claimed herein include a cellular cushioning system comprising a first matrix of void cells, and a second matrix of void cells opposing the first matrix of void cells, wherein one or more peaks of each void cell in the second matrix is attached to one or more peaks of each void cell in the first matrix, and wherein the void cells of the first matrix have a higher cell resolution than the void cells of the second matrix. In another implementation, a method of manufacturing a cushioning system includes molding a first matrix of void cells, molding a second matrix of void cells, the void cells of the first matrix having a higher cell resolution than the void cells in the second matrix, and attaching peak surfaces of the void cells of the first matrix and peak surfaces of the void cells of the second matrix together.

A waterbed system for placement on a ground surface can comprise one or more of the following components: a waterbed mattress, a foam structure around the periphery of the mattress, a platform below the mattress and the foam periphery for supporting the waterbed mattress and the foam structure, a foundation coupled to and extending downwardly from the platform, preferably a single, fire resistant polyester fiber baffle disposed within the waterbed mattress, a cover over the top surface of the mattress and around the outer surface of the foam structure, a water proof liner below the bottom surface of the mattress, a water bed heater under the liner between the liner and the upper surface of the platform, a layer of fiberglass insulation attached to the lower surface of the platform, and an accessory storage container coupled to the foundation.

The present invention provides systems, methods, and articles for temperature conditioning a surface. An article is formed from a first layer having a plurality of openings and a second layer having a corresponding plurality of openings. At least one interior chamber constructed and configured to retain a fluid without leaking is defined between an interior surface of the first layer and an interior surface of the second layer. At least one flexible fluid supply line delivers the fluid to the at least one interior chamber. At least one flexible fluid return line removes the fluid from the at least one interior chamber. At least one control unit that is operable to selectively cool or heat the fluid is attached to the at least one flexible fluid supply line and the at least one flexible fluid return line.

An infant care device and mattress for use with the infant care device for supporting the weight of an infant during normal use and during resuscitation. The mattress includes a non-Newtonian fluid that supports the weight of the infant. The non-Newtonian fluid allows the mattress to act as a pressure diffusing mattress when the infant patient is placed on the mattress for an extended period of time. The non-Newtonian fluid reacts to a force applied to the mattress, such as during resuscitation, such that the non-Newtonian fluid stiffens and provides the required support for the infant during such resuscitation. The non-Newtonian fluid is contained in one or more flexible pouches positioned within a mattress body. The mattress of the present disclosure thus replaces the need for a separate foam mattress and pressure diffusing mattress.

Adjustable mattress assemblies are described in which a mattress incorporates regions where additional pressure reduction is adjustable via pliable fluid bladders filled with a gas or fluid. Such areas of the mattress where additional pressure reduction is desired may include regions of the mattress which support areas of the body which may be particularly susceptible to pressure ulcers such as the heels, sacral regions, etc.

A body support article cover that includes a plurality of segments comprising a gel layer integrated with a foam layer is provided. The segments are enclosed by stitching. Each of the segments comprises a gel structure coupled with a foam layer, the gel structure comprising a gel layer. The gel layer comprises a first gel lattice having a first geometric shape. The first geometric shape has a first gel lattice height; a first gel lattice width; and a first gel lattice length. The first gel lattice comprises a plurality of first gel segments, wherein the first gel segments define a plurality of first gaps. The first gel lattice has a first firmness.

A waterbed frame assembly for rolling a waterbed on a surface includes a box that defines an interior space. The box has a top that is open so that the top is configured to insert a waterbed mattress into the interior space. A frame is coupled to a bottom of the box. The frame comprises a plurality of interconnected crossbeams so that the frame is gridded. The frame comprises metal. A plurality of rollers is coupled to the frame. The rollers are opposingly positioned on the frame relative to the box. The rollers are configured to facilitate locomotion of the box on a surface.
