本文在分析可用性定义及Jacob Nielsen、ISO9241-11、Shackle、SUMI等建立的可用性因素结构模型的基础上,结合生化分析仪的应用环境、专业性及问卷调查提取的可用性一级、二级因素,建立了适合生化分析仪人机界面的可用性因素结构模型,并对模型中的可用性因素进行了权重考量.最后,以校企合作医疗项目的人机界面设计应用为例,来验证上述模型.该模型不但有助减轻医疗设备研发人员及医护操作人员的脑力负荷,还提高了其工作效率和工作质量.%Based on the analysis of usability definition and usability factor structure models established by Jacob Nielsen、ISO9241-11、Shackle and SUMI, combined with the application environment and professional of biochemical analyzer, and the primary and secondary factors extracted from the questionnaire survey, this paper established usability factor structure model for man-machine interface of biochemical analyzer, and the usability factors of the model were weight considerations. Finally, application of the man-machine interface design from the university-enterprise cooperation medical project was used as an example to verify the effectiveness of the above model. This model could not only reduce the mental workload of R & D personnel of medical device and medical personnel, but also improve their work efficiency and quality.
