ICU无线输液与监护系统的ZigBee网络

Wireless transfusion controlling and monitoring system via ZigBee in ICUs

无线输液监护网络方便医生对重症病人实施各种诊疗操作,而且可以实时根据病情变化来及时调整输液治疗方案。本文构建了基于ZigBee的ICU无线输液监护系统,包括集成生理参数检测及无线收发功能的微型化传感器通信模块、星型躯域传感网、床边输液监护基站、护士中央服务器。临床实验对多个病人的心电、脉搏、血氧、呼吸四个生理参数进行连续24小时无线监护并反馈输液控制。结果表明,该网络具有稳定性高、抗干扰能力强、功耗低等特点。该研究创造性地利用ZigBee无线通信技术构建输液监护系统,打破传统的ICU诊疗模式,提高了医疗水平及对重症病人的诊疗质量。

Wireless transfusion controlling and monitoring network not only aids physicians and nurses in providing convenient treatments aml comforts to the patient but also regulates the model of therapy based on the physiologic parameters. The paper presents a wireless transfusion controlling and monitoring system via ZigBee, including sensor and radio frequency miniature modules, wireless BSNs, wireless transfusion devices, base stations, and centre server. An experiment that the patients were monitored （including ECG-Ⅱ, pulse wave SpO2 and respiration） and transfused continuously in 24 hours, demonstrates that the system is characterized by wireless, miniature, and intelligent. The advantages of the approaches utilized in our work - ZigBee wireless communication technology - break the traditional monitoring and transfusion pattern in ICU thus the quality and efficiency of medical treatment are improved.
