In order to study new methods of telemedicine usage in the context of emergency medical services, researchers need to prototype integrated telemedicine systems. To conduct a one-year trial phase-intended to study a new application of telemedicine in German emergency medical services-we used off-the-shelf medical devices and software to realize real-time patient monitoring within an integrated telemedicine system prototype. We demonstrate its feasibility by presenting the integrated real-time patient monitoring solution, by studying signal delay and transmission robustness regarding changing communication channel characteristics, and by evaluating issues reported by the physicians during the trial phase. Where standards like HL7 and the IEEE 11073 family are intended to enable interoperability of product grade medical devices, we show that research prototypes benefit from the use of web technologies and simple device interfaces, as they simplify product development for a manufacturer and ease integration efforts for research teams. Embracing this approach for the development of new medical devices eases the constraint to use off-the-shelf products for research trials investigating innovative use of telemedicine.
为了研究在紧急医疗服务背景下使用远程医疗的新方法，研究人员需要构建集成远程医疗系统的原型。为了进行为期一年的试验阶段（旨在研究远程医疗在德国紧急医疗服务中的新应用），我们使用现成的医疗设备和软件在集成远程医疗系统原型中实现对患者的实时监测。我们通过展示集成实时患者监测解决方案、研究关于通信信道特性变化的信号延迟和传输稳健性，以及评估医生在试验阶段报告的问题来证明其可行性。虽然像HL7和IEEE 11073系列这样的标准旨在实现产品级医疗设备的互操作性，但我们表明研究原型受益于网络技术和简单设备接口的使用，因为它们简化了制造商的产品开发并减轻了研究团队的集成工作。采用这种方法开发新的医疗设备，缓解了在研究远程医疗创新用途的试验中使用现成产品的限制。
