Improvement of QOL in meals of persons with difficulty in deglutition by preparation of solutions for judging aspiration symptoms

制备了在10~ 50 s ~ 2剪切速率下粘度相同<-1>、剪切变稀行为不同的多糖溶液，并进行了X射线荧光显象。对作为团注量和团注粘度的函数的抽吸风险进行了数值模拟，并支持视频透视观察。开发了监测不同症状的吸入的解决方案，分析了市售的增稠液体食品，并检查了新开发的液体食品和商业食品之间的关系，从而建立了监测吸入的系统方法的基础。

Polysaccharide solutions with the same viscosity at shear rates 10～50s^<-1> and with different shear thinning behaviours have been prepared and X-ray videofluorography was carried out. Numerical simulations on the risk of aspiration as a function of bolus quantity and bolus viscosity were performed and supported the videofluorographic observation. Solutions for monitoring aspiration with different symptoms were developed, commercially available thickened liquid foods were analyzed, and the relation between newly developed liquid foods and commercial foods was examined, and thus the basis of a systematic method of monitoring aspiration was established.
