This case study explored how human-centred design methodologies can improve clinician experience and reduce patient treatment anxiety in the application of a new dental local anaesthetic jet-injection system. An initial embodiment of the prototype injector, dubbed the 'Kiwi' injector, was developed to better understand the user experience during dental-injection procedures. Further design development was undertaken in two distinct phases. Stage one entailed the initial non-functional Kiwi injector model being used as a design probe to explore clinician views on its aesthetics and ergonomics. The second stage explored the clinician and patient experiences of the functional Kiwi Injector while administering a local anaesthetic to the patient. Stage one findings highlighted clinician satisfaction with the aesthetics of the non-functional prototype device but expressed the desire to make the device smaller. Stage two clinical study results highlighted an issue with the functional jet injector configuration, where the participating dental clinicians speculated that a greater bend in the wand and change of trigger position would significantly improve the Kiwi injector ergonomic performance. This research has demonstrated the benefits of applying a structured and staged human-centred user experience design process to inform the design of a new dental anaesthetic delivery device.
本案例研究探讨了以用户为中心的设计方法如何在新型牙科局部麻醉喷射注射系统的应用中改善临床医生体验并减轻患者治疗焦虑。开发了原型注射器的初始版本，称为“猕猴桃”注射器，以更好地了解牙科注射过程中的用户体验。进一步的设计开发分两个不同阶段进行。第一阶段是将最初的非功能性“猕猴桃”注射器模型用作设计探针，以探究临床医生对其美学和人体工程学的看法。第二阶段探究了功能性“猕猴桃”注射器在给患者注射局部麻醉剂时临床医生和患者的体验。第一阶段的研究结果突出了临床医生对非功能性原型设备美学的满意度，但表示希望将设备做得更小。第二阶段的临床研究结果突出了功能性喷射注射器配置存在的一个问题，参与研究的牙科临床医生推测，操纵杆更大的弯曲度和扳机位置的改变将显著改善“猕猴桃”注射器的人体工程学性能。这项研究证明了应用结构化、分阶段的以用户为中心的用户体验设计过程为新型牙科麻醉输送设备的设计提供信息的好处。
