一种新型骨折急救外固定器——喷塑型葡聚糖型聚氨酯外固定夹板的研制

摘要

A new production method of spraying dextran-based polyurethane external splints is introduced in this paper The main raw material components are polymethylene polyisocyanate (PAPI) , mixed with surfactants, acetone, soluble starch, catalyst, and so on. The splint is used for temporary fixing after fracture, with small size, light weight, easy portability, fine air perviousness, completely transparent to the X-ray. It also needs a shorter fixed operating time. It can not only fix quickly and effectively the vertebral column and limbs, but also significantly shorten the time of pre-hospital care.%介绍了以多甲基多苯基异氰酸酯(PAPI)为主要材料组份,辅以表面活性剂、丙酮、可溶性淀粉、催化剂等作为另一组份来研制新型的骨折急救外固定器—喷塑型葡聚糖型聚氨酯外固定夹板.该夹板供骨折临时固定使用,具有体积小、质量轻盈、携带方便,透气性好、操作简单和时间短以及完全透X射线等优点.可对伤员的四肢或脊柱进行快速、有效的固定,能显著缩短院前救治时间.
