Abstract:
Objective: To design and prepare a field battle "Windbreaker" stretcher for fixation of spinal cord injury using macromolecular material, and to determine its application index and assess its efficacy. Methods: Using shape memory waterborne polyurethaneurea/SiO2 nano-composite, we prepared a field battle "Windbreaker" stretcher for fixation of spinal cord injury according to the physique of the Chinese. The time spent to finish the fixation procedure under different conditions (raining, cold weather, land and rivers) was recorded, and the time of solidification was also observed. Results: The weight of a complete set of the field battle "Windbreaker" stretcher was (7.5±1.4) kg. The time to complete a fixation was (2.1±0.55) min in the water, (1.9±0.35) min under dry environment. The time of solidification was(7.7±1.45) min in the water and was (6.9±1.23) min under dry environment. The maximum strength the stretcher could bear was (80±5.7) kg. Conclusion: Our self-designed "Windbreaker" stretcher can be used for rapid and simple fixation of different spinal cord injuries, and the mechanics intensity meet the requirement for fixation. The stretcher can be used for fixation of spinal cord injury under different conditions of field battle.
