Abstract: An inflatable aquatic rescue board is provided having particular advantage in rescuing persons who have sustained injuries while swimming or diving, and who frequently must be held rigid to prevent further injuries while being removed from the water. Prior to inflation, the rescue board is quite flexible, permitting it to be rolled into a compact bundle for storage. Then, upon activation of a self-contained compressed gas supply, the rescue board quickly becomes stiff and buoyant to form an ideal aquatic stretcher. The board comprises a planar structure having two impervious parallel broad faces constrained to a maximum separation by internal members extending therebetween. Transverse reinforcements provide additional rigidity and two longitudinally extending flat springs facilitate unrolling of the rescue board under water during rescue.
