Judgment matrix and weights for comfort criteria.

AimsTo enhance the user experience and satisfaction of children’s medical nebulizers, and to improve adherence and the efficacy of nebulization treatments for children, this study explores an innovative design and evaluation method for children’s medical nebulizers from the perspective of user needs.MethodsFirstly, this study conducts a thorough analysis of user behaviors and their potential needs for children’s medical nebulizers through field observations, User Journey Mapping (UJM), relevant user interviews, and the KJ method, thereby constructing a hierarchical model of demand indicators. Next, the Analytic Hierarchy Process (AHP) is employed to calculate the weight and priority ranking of each indicator, effectively identifying the crucial demand indicators that influence nebulizer design. Based on the findings from the demand analysis, an innovative design practice for children’s medical nebulizers is carried out. Finally, the fuzzy comprehensive evaluation (FCE) method is used to assess the user satisfaction of the proposed design scheme and an existing nebulizer product case used in children’s hospitals and compare the results to verify the feasibility and effectiveness of the design approach and scheme in this study.ConclusionThe results indicate that the combined application of UJM, the KJ method, AHP, and FCE can help designers more accurately capture diverse user needs, enhance the scientific rigor and rationality of design and evaluation processes for children’s medical nebulizers, and ultimately produce products with higher user satisfaction. This study contributes to the field by providing a systematic framework for the design and evaluation of preschool-aged children’s medical nebulizers, offering theoretical guidance and practical reference for future designers.为提升儿童医用雾化器的用户体验与满意度，改善儿童雾化治疗的依从性与疗效，本研究从用户需求视角出发，探索儿童医用雾化器的创新设计与评价方法。 方法 首先，本研究通过实地观察、用户旅程图(User Journey Mapping, UJM)、用户访谈及KJ法，对儿童医用雾化器的用户行为与潜在需求开展全面分析，构建需求指标层级模型。随后，采用层次分析法(Analytic Hierarchy Process, AHP)计算各指标的权重与优先级排序，精准识别影响雾化器设计的关键需求指标。基于需求分析结果，开展儿童医用雾化器的创新设计实践。最后，运用模糊综合评价法(fuzzy comprehensive evaluation, FCE)对所提出的设计方案与儿童医院现有雾化器产品案例进行用户满意度评估，并对比分析评估结果，以验证本研究设计方法与方案的可行性与有效性。 结论 研究结果表明，将UJM、KJ法、AHP与FCE相结合，可帮助设计师更精准地捕捉多元化用户需求，提升儿童医用雾化器设计与评价流程的科学性与合理性，最终产出用户满意度更高的产品。本研究为学龄前儿童医用雾化器的设计与评价提供了系统性框架，为后续设计师提供了理论指导与实践参考。
