Sea and intelligent system is a kind of stretcher according to naval warfare and drainage characteristics of disaster relief and development, collection and transport, life support systems, vital signs monitoring system and information storage processing system, wireless communication system in a body's modernized the wounded transfer device, is the future naval warfare and water system, the necessary medical equipment in disaster relief, to improve the patients quality of life and battle effectiveness plays an important role. Sea patients intelligence stretcher with a strong, lightweight materials, resistance to electromagnetic interference, high salt, high humidity, low temperature resistance, data acquisition and receive automatic, wireless, intelligent, good safety performance. The intelligent stretcher will be the development direction of future Marine combat and water disaster relief stretchers, and will play a more important role.

War can cause a large number of casualties, the wounded security quickly transported to the injuries treated a line is the army medical equipment and emergency equipment is the important subject faced by researchers. Early on the battlefield of the wounded rescue only unarmed, hold back, hold and drag method, purpose is from the battlefield environment, avoid the secondary damage, in this case the military stretcher with war.

With the development of science and technology, various kinds of stretchers appeared, improving the quality of battlefield treatment and meeting the needs of different service.

At present our country ships equipped with a stretcher is mainly on 68 a stretcher Ⅱ type, also have a small amount of Robertson stretcher. In 1968 China's 68 type stretcher is developed based on the characteristics of ship structure, several improved form 68 a type Ⅱ vessels of portable stretcher, finalize the design and batch production of the armed forces in 1979, to fill the gaps in our ship without the pattern a stretcher. In addition, there are 68 "I" stretchers, and a soft stretcher suitable for carrying the wounded in the special position of the ship. In 1981, the Robertson stretcher was improved to make it more suitable for small ships.
