网络医学监护系统的设计与实现

Medical monitor system based on network communications

分析了医学监护系统的现状,指出监护设备网络化、便携化发展趋势,提出基于移动通信网络的医学监护系统整体解决方案:采用嵌入式技术,构建基于网络的便携式医疗监护设备;研制生产基于802.11b/g和CDMA的无线通讯接口模块,对传统B超、CT、MRI等影像设备及各类生物电采集监护设备进行改造和功能扩展;设计符合DICOM3.0和HL7国际标准的网络数据库,重新整合医院原有PACS系统信息资源;研制生产基于WINCE的手持式终端,实现病历数据与诊断信息的实时共享交互。

In this paper, the development trend of medical monitor system is analyzed. The portable trend and network function become more and more popular among all kinds of medical monitor devices. The architecture of medical network monitor system is provided： pocket medical monitor devices based on embedded platform is developed to interact with center database on networks; the telecommunication interface based on 802.11b/g and CDMA is designed to rebuild and extend the functions of traditional imaging devices （ultrasonic、CT、MRI） and the implementation details of terminal, monitor center software, distributed database and two kinds of medical information terminal are especially discussed; distributed medical database is designed for hospital center according to DICOM information model and HL7 standard; hand terminal based on WINCE is developed for nurse＇s routine care and doctor＇s auxiliary diagnosis.
