【摘要】：目的:构建基于物联网的胎心监护系统,使孕妇不受空间、时间限制进行胎心监护。方法:采用嵌入式单片机系统对感知层采集的胎心率、宫缩压力信号,通过蓝牙与智能手机进行双向数据发送与接收,以Eclipse开发应用层服务器平台管理软件,对数据处理后显示胎监信息、反馈诊断结果;并以足月孕妇为试验对象,以临床标准胎心监护仪为对照,计算本胎心监护系统的准确率。结果:便携式胎心监护仪准确率均在98.9%以上,胎心率检测值误差不超过±2次·min-1,压力测量非线性误差在-9.1%~+7.7%之间,两组测量值差异无统计学意义(P0.05)。结论:基于物联网的胎心监护系统运行的稳定性与监测的准确性达到设计指标要求。所研制胎心监护系统可准确检测胎心率及宫缩压力,准确反映胎儿情况,将检测信息实时传输至手机及服务器,使专家及时处理产科情况成为可能。
[Abstract]:Aim: to construct a fetal heart monitoring system based on the Internet of things (IOT) so that the pregnant women can not be monitored by space and time. Methods: the fetal heart rate (FHR) and contractive pressure signals collected from perceptual layer were collected by embedded single-chip computer system. The two-way data were sent and received by Bluetooth and smart phone. The management software of application layer server platform was developed by Eclipse. Display fetal monitoring information after data processing and feedback diagnostic results; The accuracy of the fetal heart monitoring system was calculated by using the clinical standard fetal heart monitor and term pregnant women as experimental objects. Results: the accuracy of portable fetal heart monitor was above 98.9%, and the error of fetal heart rate (FHR) was not more than 卤2 times, the nonlinear error of min-1, pressure measurement was -9.1% ~ 7.7%. There was no significant difference between the two groups (P0.05). Conclusion: the stability and accuracy of the fetal heart monitoring system based on Internet of things can meet the design requirements. The developed fetal heart monitoring system can accurately detect fetal heart rate and uterine contraction pressure, accurately reflect the fetal situation, and transmit the detection information to mobile phone and server in real time, which makes it possible for experts to deal with obstetrical situation in time.
