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

制备了在剪切速率10～50s^-1 下粘度相同、剪切稀化行为不同的多糖溶液，并进行了X射线荧光成像。对误吸风险作为推注量和推注粘度的函数进行了数值模拟，并支持了视频荧光观察。开发了针对不同症状的误吸监测的解决方案，对市售的增稠流质食品进行了分析，并检查了新开发的流质食品与商业食品之间的关系，从而为监测误吸的系统方法奠定了基础。

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.
