【摘要】:闡述了微米木纖維作為一種木材加工材料,具有一定生物醫(yī)用材料的特性。分析了微米木纖維頸椎夾板在醫(yī)用上的相容性。通過對小興安嶺紅松制備木纖維試樣的SEM照片觀察,發(fā)現(xiàn)木纖維材料的多孔結(jié)構(gòu)與人體皮膚有很好的相容性,可提高頸椎夾板的彈性和韌性。在相容性控制上,根據(jù)不同密度的木纖維在一定氣流作用下產(chǎn)生的壓力,可計(jì)算出材料的透氣率;而對木纖維材料標(biāo)準(zhǔn)重量的計(jì)算,可使頸椎夾板的重量滿足醫(yī)用的使用要求。實(shí)驗(yàn)得出:根據(jù)試樣的微觀組織分析以及參數(shù)的計(jì)算,在微米木纖維頸椎夾板模壓時控制其模壓密度,以達(dá)到其與人體皮膚的相容性。
[Abstract]:As a kind of wood processing material, micron wood fiber has some characteristics of biomedical materials. The compatibility of micron wood fiber cervical spine splint in medical application was analyzed. By observing the SEM photographs of wood fiber samples of Pinus koraiensis in Xiaoxinganling, it is found that the porous structure of wood fiber has good compatibility with human skin, and it can improve the elasticity and toughness of cervical spine splint. In terms of compatibility control, according to the pressure of wood fiber of different density under the action of certain airflow, the air permeability of the material can be calculated, and the standard weight of wood fiber material can be calculated to make the weight of cervical spine splint meet the requirement of medical use. According to the analysis of microstructure and the calculation of parameters, the density of microfiber cervical spine splint was controlled in order to achieve the compatibility with human skin.
