Abstract：
In 2017, the International Dysphagia Diet Standardisation Initiative (IDDSI) introduced the IDDSI flow test which enables patients, clinicians, caregivers, food service professionals and researchers to classify liquid thickness into five levels based on the volume of liquid remaining in a standard 10 mL slip tip syringe after 10 s of flow under gravity. Within a few months of publishing the IDDSI flow test instructions, several barriers emerged: (1) the preferred model of syringe (BD 303134) was not equally accessible around the world, causing some users to perform flow tests with alternate models of syringe; (2) differences in syringe geometry across models led to variations in IDDSI flow test results; and (3) the need to use a second syringe for sample loading added complexity and cost to end users. To address these barriers, IDDSI designed the IDDSI funnel, a novel device, which combines the geometry of the BD 303134 syringe with a kitchen funnel to facilitate easy loading of liquid samples without need for a second syringe. In this report, we compare the IDDSI flow test results across two devices: syringe BD 303134 and IDDSI funnel. IDDSI level classifications were in complete agreement with the syringe reference test results in 67/73 (92%) of the test fluids and temperature conditions with mean difference of residual liquid across devices of 0.2 (2% full scale). These results demonstrate excellent correspondence between the two devices.
摘要：
2017年，国际吞咽困难饮食标准化倡议（IDDSI）引入了IDDSI流量测试，使患者能够，临床医生,看护者,食品服务专业人员和研究人员根据在重力下流动10s后标准10mL滑头注射器中剩余的液体量将液体厚度分为五个级别。在发布IDDSI流量测试说明后的几个月内，出现了几个障碍:(1)注射器的首选型号(BD303134)在世界各地并不平等，导致一些用户使用替代型号的注射器进行流量测试;(2)不同型号的注射器几何形状的差异导致IDDSI流量测试结果的变化;和(3)需要使用第二个注射器来加载样品,增加了最终用户的复杂性和成本。为了解决这些障碍，IDDSI设计了IDDSI漏斗,一个新颖的装置，它将BD303134注射器的几何形状与厨房漏斗相结合，以便于在不需要第二个注射器的情况下轻松装载液体样品。在这份报告中,我们比较了两种设备的IDDSI流量测试结果:注射器BD303134和IDDSI漏斗.在67/73（92％）的测试流体和温度条件下，IDDSI水平分类与注射器参考测试结果完全一致，设备上残留液体的平均差为0.2（满量程为2％）。这些结果证明了两个器件之间的优异的一致性。
