From the stretcher varieties, functions and security needs of China's ship stretcher mainly in the following aspects: ① less variety of varieties. At present, China's ships are mainly equipped with a 68-Ⅱ stretcher, placed in the ship's infirmary, the other stretchers in the ships are not officially installed, compared with the military far from the gap. US military ships have Robertson stretcher, Stokes stretcher and other stretchers, stretchers fixed in the ship corridor wall, 2 for a group; in the cruiser there are four 50 pairs, frigates have two 15 pairs. The Swedish Navy's Cascade of the mine can be seen everywhere in the corridor wall and the escalator at the Robertson stretcher. The French naval aviation team is even capable of floating floats. ② lack of function, poor adaptability. 68 a type of stretcher can be in a certain range of ships within a narrow space to transport sick and wounded, but the lack of reliable ability to fix the spine wounded. The canvas fabric used is too heavy to make the stretcher too large. By the technical conditions at that time, the material can not be well adapted to the ship's high temperature, high humidity, high salt and alkali environment, easy to change color and corrosion, for most people now the strap handle is short, affecting the comfort of the stretcher carrying the stretcher, Bulky, less mobility. 68-Ⅱ type stretcher with aluminum alloy as a framework, canvas stretcher surface, a fixed wounded lace, to solve the ship open environment wounded handling problems; but for some of the more narrow space position of the ship, because its length can not be changed, Stretcher can not pass, nor can it be used for direct transfer of the wounded.

In modern naval warfare, air raid and precision-guided weapons, the use of non-lethal weapons caused by the death of the group caused by the probability of greatly increased, in order to improve the level of naval combat warships to save the lives of sick and wounded, reduce the mortality rate, The new requirements of the wounded rescue, improve the combat effectiveness of the troops, it is necessary to develop a new type of casualty system.
