摘要目的 构建基于5G通讯技术的大型社会活动医疗急救保障信息系统,以提高医疗保障服务的水平和效率.方法 研究于2016年3月至2019年9月在杭州完成.基于大型社会活动医疗急救保障的需求和服务流程,围绕现场急救-上报指挥中心-专家远程会诊-救护车调度和转运-医院接收的过程,建设现场急救移动终端、车载急救终端、专家远程会诊终端、医院终端和指挥调度中心5个信息终端,实现文本、患者生理指标、音频、图片、视频信息的即时互通和智能化调度决策.结果 成功构建基于5G的大型社会活动医疗急救保障系统,由指挥监控平台、现场救援平台、后送支援平台三大部分组成.(1)指挥监控平台通过Web页面,展示现场医疗组、救护车、医院、专家的信息并实现随时的多方视频交流,以及患者目前病情的文本、声音、图像信息,实现指挥调度、显示统计汇总信息.(2)现场救援终端包括患者信息输入、视频信号采集和生理信息获取设备,实现多种方法病情录入、生命体征和生理信息采集、多角度视频获取,传输至指挥中心.(3)后送支援平台包括车载急救终端、远程专家会诊终端、医院终端和无人机系统.车载终端可以和现场救护组进行扫描交接,转运途中病情和生理信息记录,也可以获取和传递监护仪、心电图和超声信息.医院终端能够第一时间获取患者信息,做好院内急救准备.远程专家端可以受指挥中心和医院终端调度,随时加入远程会诊.无人机系统可以实现任何两个地点之间的物资转运.结论 本系统能够初步满足大型社会活动医疗急救保障的需求,实现现场急救-救护车转运-医院救治过程中快速的信息传递、调度决策和统计汇总功能,有待于在完整的5G网络和真实场景下不断优化.

abstractsObjective To develop medical emergency support information system for large-scale social activities based on 5G communication technology to improve efficiency of emergency medical services.Methods The project was completed in Hangzhou,China,from March 2016 to September 2019.Based on the medical service of large social activities,five information terminals are constructed,including on-site mobile terminal,on-board first aid terminal,expert remote consultation terminal,hospital terminal,and command dispatch center.The system can realize the real-time communication of medical information,patient's vital signs,audio,picture and video information,and can also make intelligent scheduling decisions for patients.Results 5G Emergency Medical information System for Large-scale Social Activities has been completed,which consists of three parts:command and control platform,onsite rescue platform,and evacuation support platform.The command and monitoring platform displays the information of on-site medical teams,ambulances,hospitals and experts through web pages,and realizes multi-party video communication at any time,as well as text,voice and image information of patients' current condition,so as to realize command,dispatch and display statistical summary information.On-site rescue terminal includes patient information input,video signal acquisition and physiological information acquisition equipment.It realizes multiple methods of patient information input,vital signs and physiological information acquisition,multi-angle video acquisition and transmission to the command center.The evacuation support platform includes vehicle emergency terminal,remote expert consultation terminal,hospital terminal and UAV system.Vehicle terminal can scan and transfer with on-site ambulance team,record physiological information during transit,and also acquire and transmit monitor,electrocardiogram and ultrasound information.Hospital terminals can obtain patient information at the first time and prepare for first-aid in hospital.The remote expert terminal can be dispatched by the command center and the hospital terminal,and can join the remote consultation at any time.Unmanned aerial vehicle (UAV) system can transfer medical material between any locations.Conclusions This system can guarantee the patients to be transported from the scene to the ambulance and finally to the hospital during the large-scale social activities.In the whole process,the information transmission and dispatching decision-making are initially realized,and the statistical report forms can be made.However,to fully exert its advantages,it still needs the support of the complete 5G network and continuous optimization in real scenarios.
