| 摘要: |
| 目的:自行设计制备野战“风衣式”高分子材料脊柱脊髓损伤外固定担架,测定应用指标,评价应用效果。方法:应用高分子形状记忆聚氨酯脲纳米复合材料,根据中国人体形制作野战“风衣式”脊柱脊髓损伤外固定担架,记录不同天气(下雨、寒冷)、不同环境(陆地、江河)下完成外固定操作的时间,测量其固化时间及强度。结果:一套完整野战“风衣式”高分子材料的外固定担架质量为(7.5±1.4) kg,完成单例外固定操作的时间为水中(2.1±0.55) min,干燥环境中(1.9±0.35) min；外固定担架固化时间为水中(7.7±1.45) min,干燥环境中(6.9±1.23) min；外固定担架能承受的最大质量为(80±5.7) kg。结论:自制野战“风衣式”高分子材料脊柱脊髓损伤外固定担架可以迅速便捷进行脊柱不同部位的外固定,固化后力学强度可达到制动要求,能适应不同野战条件的需求。 |

| 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. |
