【摘要】：麻醉机是手术室不可缺少的重要麻醉设备，其功能是向病人提供氧气，吸入麻醉药剂并进行呼吸管理，在保障病人术中生命安全方面有着不可估量的作用。随着电子技术的快速发展以及医疗仪器智能化概念的普及，嵌入式系统在麻醉机中的应用越来越广泛。本文从系统稳定性和智能化角度出发，设计并实现了基于嵌入式Linux系统和图形用户界面MiniGUI的麻醉机主控端软件。在充分掌握麻醉机工作原理的基础上，进行了完备的需求分析，采用软件分层设计思想，将麻醉机主控端应用程序分为交互层、业务逻辑层和界面显示层。其中交互层处理应用程序和Linux系统的直接信息交互，负责硬件设备的控制和读写；业务逻辑层是应用程序的核心部分，主要完成数据的分析处理、数据存取以及报警判定等功能；界面显示层负责数据显示和窗口切换，实现人机交互式用户界面。从功能模块的角度出发，模块化实现各层次内的各项功能，模块间采用接口函数进行通信，使程序设计、调试和维护等操作简单化，提高了软件架构的灵活性。开发完成后，进行了系统功能和性能测试，以提高系统的安全性和稳定性。本设计在基于S3C2440芯片构建的嵌入式Linux系统平台上运行，测试结果为，系统能够动态顺畅刷新波形曲线，正确显示监护参数，实时触发安全报警，通过相应按键操作可以对通气模式、报警上下限等参数进行灵活设置，且各窗口间切换自由，，系统能长时间稳定良好运行。结果表明，本系统运行稳定，人机交互式界面清晰友好，操作简便快捷。系统中麻醉机软件设计具有较高的实际价值和意义，同时本系统的实现也可为其他医疗仪器的软件开发提供参考。
[Abstract]:Anesthetic machine is an indispensable and important anaesthesia equipment in operating room. Its function is to provide oxygen to patients, to inhale anesthetic and to manage breathing, which plays an inestimable role in ensuring the safety of patient's life during operation. With the rapid development of electronic technology and the popularization of the concept of intelligent medical instruments, embedded systems are more and more widely used in anesthetic machines. From the point of view of system stability and intelligence, this paper designs and implements the main control software of anesthetic machine based on embedded Linux system and graphical user interface (MiniGUI). On the basis of fully mastering the working principle of anesthetic machine, a complete requirement analysis is carried out. The application program of the main control end of anesthetic machine is divided into three layers: interaction layer, business logic layer and interface display layer by adopting the idea of software layering design. The interaction layer deals with the direct information exchange between the application and the Linux system, and is responsible for the control and reading and writing of the hardware devices, and the business logic layer is the core part of the application program, which mainly completes the analysis and processing of the data. The interface display layer is responsible for data display and window switching, and realizes the man-machine interactive user interface. From the point of view of function module, the modularization realizes the functions in different levels. The interface function is used to communicate between modules, which simplifies the operation of program design, debugging and maintenance, and improves the flexibility of software architecture. After the development, the system function and performance were tested to improve the security and stability of the system. The design runs on the embedded Linux system platform based on S3C2440 chip. The test results show that the system can refresh the waveform curve dynamically and smoothly, display the monitoring parameters correctly, and trigger the security alarm in real time. The parameters such as ventilation mode and alarm upper and lower limits can be set flexibly by the corresponding key operation. The system can operate stably and well for a long time. The results show that the system runs stably, the man-machine interactive interface is clear and friendly, and the operation is simple and fast. The design of anesthetic machine software in the system is of high practical value and significance. At the same time, the realization of this system can also provide reference for the software development of other medical instruments.
