Despite use of colour-coded labels, syringe substitution (syringe swap) error of anaesthetic drugs remains a frequent and potentially serious cause of iatrogenic harm. We explored the novel concept of using a simple device which can be fitted to existing syringes, and employs colour and raised elements (detents) to provide visual, haptic and auditory cues to supplement the visual cues provided by standard drug labelling, and particularly helps to differentiate, for example, syringes containing vaso-active drugs from other syringes. We produced six different embodiments of the device, and performed a randomised unblinded study with 14 volunteers to identify the functional characteristics which met with the approval of the majority of participants, and the mechanical characteristics which produced adequate haptic feedback without excessive resistance to injection. The optimal design was identified, which required the user to exert a mean (SD) force of ~20 (7) N to overcome the resistance of the detents in the syringe. The majority of volunteers felt that a device of this type would be helpful in reducing the incidence of syringe substitution error; however, further research is needed to assess the efficacy of this innovation in the clinical environment.
尽管使用了颜色编码标签，但麻醉药物的注射器替代（注射器交换）错误仍然是造成医源性伤害的一个常见且潜在严重的原因。我们探索了一种新颖的概念，即使用一种简单的装置，可以安装在现有的注射器上，并采用颜色和凸起元素（定位器）来提供视觉、触觉和听觉提示，以补充标准药物标签提供的视觉提示，特别是有助于区分，例如，含有血管活性药物的注射器与其他注射器。我们制作了该装置的六个不同实施例，并对 14 名志愿者进行了随机非盲研究，以确定符合大多数参与者认可的功能特征，以及产生足够触觉反馈而不会对注射产生过度阻力的机械特征。确定了最佳设计，使用者需要施加约 20（7）N 的平均（SD）力来克服注射器定位器的阻力。大多数志愿者认为这种类型的设备将有助于减少注射器替代错误的发生；然而，需要进一步研究来评估这种创新在临床环境中的效果。
