A rescue toboggan, also known as a rescue sled,〔 (【引用サイトリンク】 Ultralite Rescue Sled ) 〕 akia (also spelled ackja, akija, and akja),〔 (【引用サイトリンク】 Rescue Toboggans ) 〕 or emergency rescue sledge,〔 〕 is a carrier for transporting a person or goods on snowy or icy surfaces. It is commonly used for wintertime mountain evacuation of an injured skier or snowboarder. There are related designs for use on water to carry accident victims or emergency equipment. A rescue toboggan takes the form of a pulk or small sled shaped as an elongated boat-like pan, usually made of aluminum or fiberglass,〔 (【引用サイトリンク】 Company History ) 〕 with vaulted ends, each of which may be attached to forked extending handles. There are many variations and adaptations such as a brake, stability fins,〔 〕 and an integrated or removable litter. A particular variation may be preferred by various regions or individual ski patrollers. The trough has a trapezoidal cross section and the edges of the lower surfaces have three central stiffening skids. The straight bars, often made of steel pipe, lower the contour of the lower space and end with large oval rings about twice hip width. The toboggan is directionally symmetrical so it can move either head first or foot first. When empty or with a light load, it can be handled by one person alone. With a full load or a well secured person in it, it requires two rescuers on skis who can take much of the weight of the load off the snow through two sets of handles to prevent passenger impacts from bumps for a smoother and safer ride with better control from four ski edges. A brake chain under the downhill end controls speed in steep terrain when pressure is applied to the front spars which proprotionally affects the location and length of the chain to regulate the braking effect. A line attached to the toboggan secures it to a rescuer. After first aid or other initial medical treatment, the patient is placed in the toboggan wrapped in a vacuum mattress or insulating pads, and wrapped with a windproof blanket. Heat reflective emergency blankets reflect thermal radiation and heating packs, hot water bottles, or electric blankets might be used to warm the patient. If the patient has injuries to the lower extremities and must be transported over longer steep distances, she is additionally held in a rescue seat and drawn up to relieve the legs and protect them from body weight. After securing the injured person, she is transported to a point where evacuation by vehicle can occur. The rescue toboggan and patient can be carried by ambulance on roads or by a rescue helicopter. There are one and two piece toboggans. The latter is divisible so it can be carried on a backpack. The bars can be removed to carry the basket in a vehicle or on ski lifts and snowcats. In summer, toboggans can be used as an alternative to stretchers when on rough terrain. For longer distances on trails or other grounds, a centrally-placed wheeled axle carries a large proportion of the patient's weight. Previous models were made of wood. == History == Akias were used by Finnish military atleast from the 1930's, after that being adopted by ski patrollers and rescuers around the world, such as Mount Hood Ski Patrol to replace dogsleds. 〔 (【引用サイトリンク】 History of the Mount Hood Ski Patrol ) 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rescue toboggan」の詳細全文を読む スポンサード リンク
