Recently published International Dysphagia Diet Standardisation Initiative (IDDSI) framework provides a new global guideline on texture modification and standardisation for dysphagia patients. The IDDSI flow test determines the usage of the 10‐mL syringe with a fixed length from the zero to the 10‐mL line engraved on the barrel. The objective of this work was to investigate the influences of the other syringe geometries on the IDDSI test. Three syringes of different geometries were used for the test. Results from the IDDSI test (i.e. the amount of residue in the syringe after the gravitational flow for 10 s) depended on the syringe geometries. The actual amount of residue in the syringe can be predicted by calculation using the Hagen–Poiseuille equation. Most importantly, results from the simulation of the residue with changing the syringe geometries demonstrated that the nozzle inner diameter is the most important factor on the IDDSI flow test.

注射器几何形状对国际吞咽困难饮食标准化倡议流动试验的影响

最近发布的国际吞咽困难饮食标准化倡议（IDDSI）框架为吞咽困难患者的质地改良和标准化提供了新的全球指南。IDDSI流量测试确定使用10毫升注射器的用法，该注射器具有从零到刻在笔筒上的10毫升线固定长度的长度。这项工作的目的是调查其他注射器几何形状对IDDSI测试的影响。测试使用了三个不同几何形状的注射器。IDDSI测试的结果（即重力流10秒钟后注射器中的残留量）取决于注射器的几何形状。可以通过使用Hagen-Poiseuille方程进行计算来预测注射器中的实际残留量。最重要的是，
