A one piece air mattress suitable for use in health care settings to aid in prevention of bed sores has air cells permanently attached to a common base sheet along a base perimeter of each cell. The air cells and base sheet are of flexible radio frequency weldable plastic material, and all the air cells can be simultaneously welded to the base sheet in a single welding step using a special welding jig. Air supply conduits are defined by strips bonded to the base sheet in overlying relationship to orifices opening the supply conduits to the air cells, thereby eliminating the need for external air hoses and connections. An alternating pressure air mattress can be made by opening different air supply conduits to alternating sets of the air cells.

The present invention is method and resulting assembly for applying a flexible liner to a cementitious vault wall, wherein several forms are described for attachment of the liner to flowable and fully cured cementitious vault walls.

An inflatable mattress for clinical bed use has a base pad including two sheets joined to define one or more narrow air conduits extending along the pad. A body supporting surface is provided by individually detachable inflatable elements covering the base pad. Each inflatable element is secured across the pad transversely to and communicates with at least one air conduit through apertured fasteners. Air permeable foam in the air conduits holds the conduits open in a gatched condition of the pad. Cushioning material contained between the sheets exteriorly to the air conduits provides body support in the event of deflation of the mattress. Constant pressure and alternating pressure modes of operation are supported with appropriate air supply systems.

An inflatable overlay for a bed mattress has a base sheet with a top and sides sized to retentively fit over the mattress, and inflatable elements secured to the sheet defining a body support surface. Impermeable sheet material is layered on the base sheet to form air conduits connected for supplying the inflatable elements. The overlay is pliable and can be folded or rolled for transport and storage.

Generally, the present invention is directed to a cellular air loss mattress system comprising an air mattress and an air supply means. Cells of the mattress system are welded onto a unitary top piece and a unitary bottom piece. Means for supplying air, preferably an air blower, is connected to the center cell (also referred to as the pelvic cell) via a supply hose. The air exiting the air blower travels through the supply hose and fills the center cell. The air is allowed to directly travel into adjacent cells via internal air connectors. The inner diameter of each air connector is adjusted to create different pressure zones within the air mattress to support the different pressure requirements of a patient's body. The highest pressure zone is the center cell that initially receives air from the air supply means. The pressure decreases as air moves from the center cell to adjacent cells. The top piece of the air mattress preferably has a plurality of tiny holes that allows for air to escape to help maintain the patients skin and to help prevent skin breakdown.

An air support unit for use in a modular air support bed has a common base pad of pliable material and inflatable elements releaseably fastened to one side of the base pad to define a body support surface. The air support unit constitutes a lightweight, foldable module easily and quickly interchangeable in a given bed with other modules having different patient support characteristics. The air support unit may be contained in a coverlet having a detachable top for easy access to the air support unit. An interior frame of resilient foam may be provided around the air support unit inside the coverlet for enhanced edge support.

A watermattress having a first sheet and a second sheet forming a container for receiving water includes a third sheet for dividing the container into a bladder for receiving water and a cavity. A sheet of foam including portions which define a plurality of holes is disposed in the cavity where means is provided for joining the second sheet and the third sheet through the holes in the foam sheet for maintaining the foam sheet in its generally planar configuration within the container.
