ABSTRACT:
A halo vest (for cervical and spine injuries) having a body of structural material such as hard plastic has halo supporting rods and a halo attached to it. A lining of wicking material is provided for the vest body. The vest body has a surface configuration that avoids pressure on bony prominences, has flat surfaces at flat bone areas and curved surfaces at curved bone areas of the user, and exerts less than about seven pounds per square inch pressure on the wearer's skin. No dimension from an interior surface point to the closest peripheral portion is larger than the ability of the lining to readily wick liquid from the interior surface point to the peripheral portion so as to avoid skin wetness. The lining comprises a first layer of water proof and vapor proof material like cross-linked closed cell polyethylene foam having grooves to facilitate transport of liquid toward the periphery of the vest, and a second layer of soft, wicking textile material that is air, water, and vapor permeable. The textile material, such as a bunting material about one-quarter inch thick, is releasably attached (e.g. with hook and loop fasteners) to the vest body interior surface.
