In recent years, due to climate reasons, floods have occurred in many places, and flood rescue stretchers are portable and systematic rescue tools. The design point is divided into three points, one is to use the fabric heated in contact with water to preserve the patient's body temperature. The second is to adopt the deployment method of automatic inflation of water absorption to speed up the rescue process. The third is that the inflatable fabric is waterproof and non-slip, and the rescue error is reduced as much as possible. It systematically optimizes the entire rescue mode, better protects the life safety of the rescued, and provides a new idea for related flood disaster rescue methods.
