智慧病房无线呼叫系统的设计与实现

Design and Implementation of Wireless Call System for Smart Wards

现有的病房呼叫系统大多采用有线网络,布线成本高,护士只能采用固定终端接听,移动性较差。为此,基于无线网络设计并搭建一套智慧病房无线呼叫系统,系统组件包括床头屏、门口屏和护士站呼叫主机,系统中创新性地引入了手持式移动护理终端(PDA)以实现移动接听。该呼叫系统在某院试点病区已稳定运行一年以上,统计数据表明引入该无线呼叫系统后,护士接听患者呼叫的响应率高达89.41%,大多护士反馈PDA的移动接听功能提高了接听效率。满意度调查结果显示,护士对系统的总体满意度为4.28分(满分5),推荐给其他病区的意愿度为4.38分(满分5)。因此,该无线呼叫系统具有低布线成本和高移动性的优点,有较高的应用和推广价值。

Most existing ward call systems use wired networks,which have high wiring costs.Nurses can only use fixed terminals to answer,resulting in poor mobility.To this end,a smart ward wireless call system is designed and built based on wireless networks.The system components include a bedside screen,a doorstep screen,and a nurse station call host.The system innovatively introduces a Personal Digital Assistant(PDA)to achieve mobile answering.The call system has been running stably in a pilot ward of a certain hospital for more than a year.Statistics show that after the introduction of the wireless call system,the response rate of nurses answering patient's calls is as high as 89.41%.Most nurses have reported that the mobile answering function of PDA has improved the efficiency of answering.The satisfaction survey results show that the overall satisfaction of nurses with the system is 4.28 out of 5,and the willingness to recommend to other wards is 4.38 out of 5.Therefore,the wireless call system has the advantages of low wiring cost and high mobility,and has high application and promotion value.
