Design and Application of the Smart Infusion Monitoring Based on the Bluetooth of Low Energy

目的为了直观显示临床输液滴速和剩余液体量,设计一套智慧输液系统提高临床工作效率,促进临床合理用药,提升患者就医体验。方法针对输液结束不能及时提示和滴速不可见等问题,使用智慧输液系统进行剩余液量和滴速显示,解决输液结束预警问题;对比蓝牙技术与其他物联网技术性能,指出低功耗蓝牙技术在输液监测系统中应用的优势,提出智慧输液监控信息化系统建设方案并应用。结果基于低功耗蓝牙技术的智慧输液系统使用后,护士换液平均时间由(4.37±1.79)min缩短至(2.47±0.89)min,病房输液响铃率由65.31%±4.65%降低至38.69%±3.96%,其差异均有统计学意义(P<0.05)。结论基于低功耗蓝牙技术的智能输液系统可提高临床工作效率,打造安静病房,促进了临床合理用药,提升患者就医体验。

Objective In order to intuitively display the dripping rate and residual fluid volume of intravenous infusion,the smart infusion monitoring system is designed and applied to improve the clinical work efficiency,promote rational clinical drug use,and improve patients’medical experience.Methods In view of the problems such as failure to prompt the end of infusion and invisible drip rate,the intelligent infusion system was used to display the remaining liquid amount and dripping speed,so as to solve the problem of early warning at the end of infusion.By comparing the performance of bluetooth low energy(BLE)technology with other internet of things technologies,the advantages of BLE technology in the application of infusion monitoring system were pointed out,and the construction scheme of intelligent infusion monitoring information system was proposed and applied.Results After the intelligent infusion system based on BLE technology was used,the average fluid change time of nurses was shortened from(4.37±1.79)min to(2.47±0.89)min,and the call of infusion rate in the ward was reduced from 65.31%±4.65%to 38.69%±3.96%,with statistical significance(P<0.05).Conclusion The smart infusion system based on BLE technology can improve clinical work efficiency,create a quiet ward,promote clinical rational drug use,improve patients’medical experience.
