【摘要】 目前我国医院信息化建设相对滞后,大部分县级以上医院以财务信息为中心的医院管理信息系统基本实现,以病人医疗数据为中心的临床信息系统建设尚处于起步阶段。体检信息系统是临床信息系统不可缺少的一部分。随着个人数字助理(PDA)和无线局域网(WLAN)技术、产品日益成熟和硬件价格降低,PDA和WLAN己倍受各行业青睐,为开发移动体检信息系统创造了条件。 本文介绍了开发基于PDA和WLAN的体检信息系统的课题来源、国内外应用现状、研究意义和内容,进行了系统业务和技术背景分析、无线局域网设计、模块划分和分析、体检移动数据库设计。分析了WLAN的标准DCF算法、构造了吞吐量优化模型、设计了吞吐量优化算法,进行了吞吐量优化仿真。对远程数据存储、软件功能、数据表结构、软件界面进行了实现。实现了体检信息录入、汇总、统计、分析、查询、体检预约、收费和工作量统计等功能和体检过程移动化检验、无纸化办公、数字化信息采集、网络化通信和规范化输入输出。 建立基于PDA和WLAN的体检信息系统有利于提高体检工作的服务质量、效率、经济效益和医院市场竞争力,促进医院信息化建设。更多还原

【Abstract】 Nowadays the construction of hospital informationization relatively lags behind, hospital information management mainly in financial information is realized in most hospitals above county level. However, the clinical information system based on patients’ medical treatment data has just got started, in which the health examination information system is indispensable. With the maturity of techniques in both personal digital assistant (PDA), wireless local area networks (WLAN) and the increasingly lower cost of hardware, the PDA and WLAN are becoming more and more adopted in all walks of life, which provide chances for developing mobile health examination information system.This paper aims to introduce research origin based on the development of health examination information system with the PDA and WLAN, significance, and contents of the research. Having analyzed health examination work and technical background, we designed a series of wireless local area networks projects, software modules, and mobile health examination database. We have put forward wireless local networks standard distributed coordination function arithmetic, so as to set up a kind of throughput optimization modules, design the throughput optimization arithmetic and simulate the arithmetic. We have realized retrieving and saving of remote PDA data, software function, database table structure, user’s interface, etc. We have also realized such functions as inputing of health examination information, totaling, summarizing, analyzing, inquiring, making health examination appointments, collecting fees, summarizing amount of work, as well as mobilizaion test of health examination process, paperless office work, collecting digital information, standardizing input and output of networks communication.Setting up health examination information system based on PDA WLAN will contribute to better service, higher efficiency, stronger competibility among hospitals, and promote construction of hospital informationization.更多还原
