摘　　要：目的:设计一种基于nRF905有源RFID芯片的无线呼叫系统,并在医院门诊输液系统中集成应用。方法:系统采用低功耗的nRF905有源RFID芯片,无线呼叫系统由10台呼叫接入网关和多台终端呼叫器构成,呼叫接入网关与每一台呼叫器之间以双向通信方式传递数据,并能够把相关的呼叫信号转发至上位机服务器中,供应用系统使用。结果:通过在医院移动门诊输液系统中的应用表明,该系统架构清晰,工作稳定可靠。结论:该无线呼叫系统明显改善了医院门诊输液环境,优化了输液呼叫流程控制,提高了患者满意度。Objective To design a wireless calling system with nRF905-based active RFID chip and integrate it into the outpatient infusion system. Methods Besides low-power-consumption RF905 active RFID chip, the calling system was composed of an access gateway and multiple calling devices. Bidirectional data communication was performed between the gateway and calling devices, and the calling signals were transmitted to the upper server. Results The clinical trial proved the stability and reliability of the system. Conclusion The system improves the outpatient infusion condition and optimizes the flow for infusion calling.
