目的 麻醉呼吸机用户界面是人机交互的接口,也是麻醉呼吸机性能最直观的反映.为兼顾性价比与用户界面的清晰美观,设计了基于嵌入式Linux和图形用户界面MiniGUI的麻醉呼吸机界面应用程序.方法 根据麻醉呼吸机工作原理及其功能需求,总体设计采用软件分层方案,考虑到内容的合理显示以及资源的高效利用,界面显示层采用模块化设计.结果 本系统在基于AT91RM9200的平台上能够良好运行,界面自然友好,便于操作.结论 该用户界面设计方法具有较大的实用价值和意义.%Objective The user interface of anesthesia ventilator is the interface of the human-machine interaction, and the most direct reflection of the performance. To take both the cost performance and the clarity of the interface into account, the user interface of anesthesia ventilator based on embedded Linux and the graphical user interface MiniGUl was designed. Methods According to the working principle and functional requirements of anesthesia ventilator, a layer scheme was used in the overall software design. We adopted modular design to implement the interface display layer, considering the reasonable display of the content and efficient utilization of the resources. Results The system ran on the platform of AT91 RM9200 successfully and the results indicated that this system worked well and the user interface was natural, friendly and easy to operate. Conclusions This user interface design might have great practical importance and value in the interface of the human-machine interaction.
