Natural disasters, accidents and public safety events have been happening all the time since ancient times. Rescue and rescue has always been a concern of people in various disasters. The stretcher is an important medical tool for transporting the injured during the rescue process. Usually, at the disaster disaster site, the road is uneven, and the stability of the stretcher is difficult to ensure when the rescuer carries the stretcher. In addition, in the city, most people live in high-rise buildings. When serious illnesses such as strokes cannot move autonomously, ambulance personnel also need to use the stretcher to carry out rescue. For buildings without elevators, patients who are transported by stairs are prone to tilt. Even overturned.

In the early stage of ambulance, excessive tilting during handling will not only increase the suffering of the wounded and sick, but also cause the sick and the sick's condition to deteriorate. It is easy to cause secondary injuries to the wounded and sick, which makes the rescue efficiency greatly reduced, especially for The wounded and sick of fractures, internal injuries and internal bleeding may even endanger their lives. Therefore, it is important to keep a critically ill person in order to maintain a correct body posture. For patients with fractures, a relaxed posture should be maintained to reduce the compression of the bones. For patients with cardiac arrest and respiratory arrest, they should be lying on a hardwood bed to avoid distortion of the head and neck trunk. In addition, the tilt of the stretcher during intravenous injection may cause air to leak into the IV tube, posing a life-threatening injury to the victim. How to make the stretcher avoid tilting to maintain stability and reduce secondary damage has become a major problem in rescue work. At present, the common hand-lifting stretcher is generally difficult to meet the rescue work under special occasions. Therefore, it is very important to study the self-balancing stretcher that is easy to operate and easy to carry to improve the rescue efficiency.
