Two different prototype mobile telemedicine systems were constructed for use in the emergency room. They could transmit physiological signals as well as video pictures and sound. One device, the mobile emergency bed (MEB), was powered by battery and had a wireless connection to the local-area network (LAN). For the other, the mobile emergency server (MES), a patient monitor, video-camera and microphone were connected by a radio-frequency link to a server. A functional evaluation and a clinical evaluation (by 12 emergency doctors in six emergency centres) were performed on both prototypes. The bandwidth and the video quality of the MEB were better than those of the MES, because of the digital transmission of the wireless LAN. The MES was better for directing patient treatment and teleconsultation; the MEB was better for static patients in the emergency centre. In general, the MES was more suitable for practical emergency telemedicine work.
构建了两种不同的原型移动远程医疗系统用于急诊室。它们能够传输生理信号以及视频图像和声音。一种设备是移动急救床（MEB），由电池供电，并与局域网（LAN）无线连接。另一种是移动急救服务器（MES），患者监护仪、摄像机和麦克风通过射频链路连接到一台服务器。对这两种原型都进行了功能评估和临床评估（由六个急救中心的12名急诊医生进行）。由于无线局域网的数字传输，MEB的带宽和视频质量优于MES。MES在指导患者治疗和远程会诊方面表现更好；MEB在急诊中心对静态患者更适用。总体而言，MES更适合实际的急诊远程医疗工作。
