Abstract
A disposable patient transfer mattress includes a rectangular top sheet, a rectangular bottom sheet, internal baffles, and a receptacle configured to receive a connector for supplying air to inflate the mattress. The bottom sheet corresponds to the top sheet, and the periphery of the bottom sheet is joined to the periphery of the top sheet. The internal baffles extend between the top sheet and the bottom sheet. Each baffle is a rectangular sheet with first and second parallel edges, and each baffle is joined to the top sheet along the first edge and to the bottom sheet along the second edge. The bottom sheet has a plurality of holes configured to provide a continuous cushion of air under the mattress when the mattress is inflated. The top sheet, bottom sheet, and internal baffles are made of fabric backed with a thermally weldable material, where the thermally weldable material faces the interior of the mattress for facilitating thermal welding of the baffles to the top surface and the bottom surface.
