摘　　要：阐述了微米木纤维作为一种木材加工材料,具有一定生物医用材料的特性。分析了微米木纤维颈椎夹板在医用上的相容性。通过对小兴安岭红松制备木纤维试样的SEM照片观察,发现木纤维材料的多孔结构与人体皮肤有很好的相容性,可提高颈椎夹板的弹性和韧性。在相容性控制上,根据不同密度的木纤维在一定气流作用下产生的压力,可计算出材料的透气率;而对木纤维材料标准重量的计算,可使颈椎夹板的重量满足医用的使用要求。实验得出:根据试样的微观组织分析以及参数的计算,在微米木纤维颈椎夹板模压时控制其模压密度,以达到其与人体皮肤的相容性。The micron wood fiber, as a wood processing material, has certain characteristics of biomedical materials. The compatibility of micron wood fiber cervical splint on the medical was analyzed. Through the observation of SEM photographs of Xiaoxing＇ anling pine wood fiber sample, it was found that the porous structure of the wood fiber materials have a good compatibility to human skin, and can improve the flexibility and toughness of the cervical splint. On the compatibility control, air permeability of the material can be calculated depending on the pressure generated by the wood fibers of different density under the action of the air flow. By the calculation of the standard weight for wood fiber material, cervical splint can meet the medical use on weight requirements. The results of the experiments show that according to the analysis of sample microstructure and the calculation of the parameters, the compatibility with the human skin can be achieved by controlling the density when molding the micron wood fiber cervical splint.
