In the market, there are many types and shapes of syringes. One of the groupings of syringe types is based on barrel volume. The shape of the product design affects performance and user perception. The aim of this study is to investigate the effect of barrel volume on its performance and user perception. We performed analysis following international organization for standardization 7886 procedures on syringe with 1 mL, 3 mL, 5 mL, and 10 mL volume. In addition, a user perception test was conducted on 29 respondents using a questionnaire with the Likert chart method. This study indicates that the bigger the syringe volume, the larger the dead space and the force to operate the piston are. A larger syringe volume also raises the volume that changes due to the plunger position increase. Meanwhile, the barrel volume does not affect water and water leakage, as we did not observe any leak during the syringe tests in our experiment. In addition, the user perception test shows that the barrel's length influences the ease of device control during the injection. The volume of the barrel negatively correlated with its effect to the environment. The safety features of all syringes are similar except for the 3 mL syringe, which has a value of 0.1 points difference to other syringes.
市场上有许多类型和形状的注射器。注射器类型的分组之一是基于筒体积。产品设计的形状会影响性能和用户感知。本研究旨在研究筒体积对其性能和用户感知的影响。我们按照国际标准化组织 7886 程序对 1ml、3ml、5ml 和 10ml 体积的注射器进行了分析。此外，我们对 29 名受访者进行了用户感知测试，使用带有李克特图表法的问卷进行。本研究表明，注射器体积越大，死腔和操作活塞的力就越大。更大的注射器体积也会增加由于柱塞位置增加而变化的体积。同时，筒体积不会影响水和漏水，因为我们在实验中的注射器测试中没有观察到任何泄漏。此外，用户感知测试表明，筒的长度会影响注射过程中设备控制的难易程度。筒的体积与其对环境的影响呈负相关。所有注射器的安全特性都相似，除了 3ml 注射器，它与其他注射器的差值为 0.1 分。
