The development of orthopedic fixing materials is a most basic and active aspect in orthopedic injury treatment.Their invention and application of early manual splints,gypsum bangs,hot-shaped splints,polymeric bangs and so on,greatly promoted orthopedic fixing performance and varied the strategies of orthopedic injury treatment.By repeated experiments and clinical trials,we developed a new orthopedic fixing material using polymeric materials.Convenient to operate,easy to remove,auto-shaped,X ray transmittable,water proof and durable,it not only satisfies the needs of fixing different parts of the body,but also remedies the defects of earlier fixing materials,and therefore has gained an extensive application as the best fixing material for the treatment of clinical and battle-field bone fractures.Further studies on it will surely better its properties,reduce its cost and lead it to a wider application.

Objective To develop a suit of rapidly-fixed evacuation stretcher for safe and convenient transportation of the wounded. Methods By making use of the expansion-shaping property of a bubble-shaped material produced by the chemical reaction of two kinds of Macromolecule materials, and the restrictive effect of body shape matching cotton fabric fixation-bag, a new type of stretcher was developed. Results It was proved by the maneuver and all kinds of traffic accidents that the field stretcher could provide dependable safeguard for the wounded, and the effect was very well. It was suitable to carry out the second or the third treatment and other transportation schemes.
