The present invention relates to a rescue stretcher for personal rescue.

There are a variety of different rescue stretcher known. Usually rescue stretcher have a linkage or a tub, which give the rescue stretcher a stiffness. As a result, a person can easily be placed on the rescue stretcher and transported stably. Rigid rescue stretcher, such as rescue pans, occasionally used by rescue workers, while providing good protection to the rescued person, are difficult to handle. In tight environments, however, it may be difficult or even impossible to move a fixed stretcher, which is usually longer than 2 meters in length and 50 cm wide. In addition, such solid support due to the dimensions are not only unwieldy in transport but also in storage.

Furthermore, flexible rescue stretcher are known. These are cloth-like and therefore flexible. Flexible carriers can be tightly packed, rolled up in particular and are thus easy to store and transport. Such rescue vehicles are used, for example, in altitude rescue. To transport a person, these can then be rolled longitudinally halfway around the person to be rescued, so that the person is stabilized in the rescue stretcher. Such rescue stretcher often has four or six handles, e.g. each on the right and left in the area of the shoulder, in the middle and at the foot end. This allows up to six rescuers to carry the person well in the rescue stretcher.

In the US 4124908 A a generally flexible rescue document for personal rescue is described, which can not only be handled flexibly, but also stored unrolled rolled up, for example, can be accommodated in a building in a predetermined place.
