technical field

The invention relates to the technical field of medical rescue tools for battlefields, in particular to a mobile unmanned bulletproof ambulance stretcher and a use method thereof.

Background technique

The rescue methods for the wounded on the battlefield have gone through the process of carrying, holding, supporting, dragging, etc. with bare hands to carrying the stretcher by two people, with the purpose of getting the wounded out of the battlefield environment quickly. Therefore, the performance of the stretcher plays a decisive role in whether the wounded can receive timely treatment. However, our army currently has fewer varieties of stretchers, and the stretchers have a single function, which is not suitable for the evacuation support requirements of modern wars. At the same time, the standardization and integration of stretcher equipment is not high. Although there are many types of stretchers that have been remanufactured, their scope of application is too narrow and they have not yet formed a standard. On the other hand, the technology of stretcher equipment is not high, and it is rare to apply cutting-edge research results in the field of materials and structures to stretchers. Most stretchers are still large in size, difficult to decontaminate, and poor in comfort. The development and parallel installation of new battlefield stretchers has become a task that must be completed in the new military transformation process.

At present, there are a complete range of ambulance stretchers and stretcher accessories on the market, including simple and easy-to-use ordinary stretchers, three-defense (nuclear, biological, and chemical weapons) evacuation bags, and integrated ventilators, suction devices, and oxygen supplies. Intelligent stretcher system for medical equipment such as system, infusion pump, defibrillator, blood gas analyzer and physiological monitor. At the same time, its scope of application is also gradually expanding, covering all services of the sea, land, air and rocket forces. There is a Robinson stretcher for the navy that is convenient for going up and down stairs in a small space in a ship, and an emergency belt suitable for air evacuation. wheel stretcher etc. Facing different types of injuries, highly targeted special stretchers have also been successfully developed, such as spine boards for spinal injuries and wounded handling boards for fractures. In addition, the new handling tools are gradually showing the advantages of high technological content, light material, high strength, easy cleaning and disinfection, etc. The product functions are not limited to simple wounded handling, and many products also integrate features such as three-proof, floating and Additional features for First Aid.

Although the products are rich and colorful, two serious problems have been overlooked. One is the mobility of the stretcher, and the other is the protection to prevent secondary damage to the wounded by conventional weapons. In frontier positions, especially in the main urban street fighting in modern warfare, if there are casualties that need to be carried back to the rear, although the method of manual lifting is convenient and quick, it cannot withstand the attack of conventional weapons, and it is very easy to cause damage to the wounded and rescue personnel. .
