针对便携式医疗仪器的特点,本文提出了一种采用嵌入式Linux操作系统和跨平台应用程序框架Qt4快速开发便携式医疗设备的方法.开发过程包括开发环境的建立,Linux和Qt编译、移植以及应用软件的设计.在此基础上,本文设计了一种手指脉搏波监测显示设备的系统软件,此实例证实应用上述方法所开发的系统界面友好,可实时、清晰地显示脉搏波形.结果表明,利用本文提出的方法开发便携式医疗仪器是一种有效、快速的开发方法.%In view of the characteristics of portable medical devices, a method to develop the device was presented, which based on embedded Linux operating system and Qt4, as a cross platform application framework. It included the establishing of development environment, the procedure of construction and porting for Linux and QT and also the method of developing application software was described. According to this method , a software of a equipment for monitoring and displaying finger pulse wave was designed. It had friendly interface and the pulse waveform was real-time and clear. The experience showed that the method was effective and rapid.
