The International Dysphagia Diet Standardization Initiative (IDDSI) proposed the flow test (FT) as a simple method for measuring the viscosity of thickened liquids. However, the FT specifies the use of a particular syringe type (BD-Slip), which is unfortunately not easily available in Japan. Therefore, the current study primarily aimed to investigate the effects of the internal syringe shape on IDDSI FT and identify the most suitable syringe available in Japan for xanthan gum-based thickened liquids. Accordingly, four syringes, namely, Luer slip tip, Luer-Lok tip, TERUMO, and NIPRO syringes, were used to examine FT value with water and nine different water viscosity levels. The correlation and systematic errors on residual FT values between the BD-Slip syringe and the other three syringes were analyzed. The two-dimensional internal shapes of the four syringes were measured using industrial computed tomography (CT) scanning. Based on the results of our FT, TERUMO had the smallest error range among the three syringes, without systematic errors. On a CT scan, three of five tip-shape parameters showed the smallest difference between BD-Slip and TERUMO syringe. Therefore, TERUMO had the smallest FT error range compared with that in BD-Slip tip syringe, indicating that TERUMO could be used as a substitute for BD-Slip when performing IDDSI FT with xanthan gum-based thickened water in Japan.
国际吞咽困难饮食标准化倡议（IDDSI）提出了流动测试（FT），作为一种测量增稠液体粘度的简单方法。然而，FT规定使用特定类型的注射器（BD-Slip），遗憾的是，这种注射器在日本并不容易获得。因此，本研究主要旨在调查注射器内部形状对IDDSI FT的影响，并确定日本市场上最适合用于基于黄原胶的增稠液体的注射器。相应地，使用了四种注射器，即鲁尔滑头注射器、鲁尔锁口注射器、TERUMO注射器和NIPRO注射器，来检测水和九种不同水粘度水平下的FT值。分析了BD-Slip注射器与其他三种注射器之间残余FT值的相关性和系统误差。使用工业计算机断层扫描（CT）对四种注射器的二维内部形状进行了测量。根据我们的FT结果，TERUMO在三种注射器中误差范围最小，且无系统误差。在CT扫描中，五个尖端形状参数中的三个在BD-Slip和TERUMO注射器之间显示出最小差异。因此，与BD-Slip尖端注射器相比，TERUMO的FT误差范围最小，这表明在日本对基于黄原胶的增稠水进行IDDSI FT时，TERUMO可以用作BD-Slip的替代品。
