Description

A fully wrapped folding stretcher

Technical Field

The utility model relates to the technical field of life-saving stretchers, in particular to a fully wrapped folding stretcher.

Background Art

In the wind power industry, tower heights range from several dozen meters to more than two hundred meters. The interior of the tower is a vertically confined space, equipped only with crude vertical ladders and simple auxiliary equipment for going up and down. Once workers working at heights suffer personal injury, especially those with spinal injuries, rescue is particularly difficult.

There are many kinds of rescue equipment at present. The first is hard rescue equipment, such as a rescue cabin stretcher, which can completely put the wounded into the stretcher, but it is too large to be lifted vertically and cannot be used through the ladder or elevator in the wind turbine tower. It is not suitable for narrow and vertically high application scenarios in the tower. The second is a mini soft stretcher similar to a five-point safety belt. Although it is small in size, it can only be used to drag the wounded. It is not suitable for people with severe trauma to the limbs or spine. If a soft stretcher is used for transportation, it is easy to cause secondary injuries to the seriously injured person because the limbs and body of the injured person cannot be fixed, aggravating the pain of the injured person, and even causing disability or death. The third is the soft stretcher used in offshore wind power. After the soft stretcher tower comes out, it needs to be replaced with a different type of hard stretcher for reverse transportation, wasting precious rescue time.
