Technical field

The utility model relates to a field rescue shock-absorbing combined stretcher vehicle, which is a detachable, easy-to-assemble medical rescue stretcher vehicle suitable for field rescue.

Background technique

Stretchers are widely used. With the advancement of science and technology, stretchers are also constantly improving and developing. From the previous single-function stretcher to the current lifting stretcher, walking wheel stretcher, scoop stretcher, negative pressure inflatable cushion fixed stretcher, etc. There are more and more types of stretchers and more and more functions. Although the stretcher has been greatly developed, its own characteristics determine that it needs to be carried by people. In the case of lifesaving in the wild, the road is often long and the road conditions are complicated. It is very laborious to carry a stretcher. If it is necessary to transfer the wounded from the mountain, it is more difficult, time-consuming and labor-intensive. Although the currently used stretcher car with universal wheels can save time and effort, it is mainly used indoors, and there are few stretcher cars for lifesaving in the wild. Based on this, it is necessary to design a shock-absorbing combined stretcher vehicle for field rescue, which combines the characteristics and functions of the stretcher vehicle and the stretcher, and can better solve the existing problems.
