【摘要】：子宫收缩和胎儿心率是孕期重要的生理特征,同时也是非常重要的临床产检参数。临床上宫缩和胎心率异常往往是早产或是流产的先兆病症,通过对宫缩和胎心率进行持续性监测能够及时地发现孕妇和胎儿存在的危险,达到预防早产或流产的目的。随着科技的发展,人们对医疗服务水平提出了更高的要求,孕妇希望医疗监护能够更加便捷,能够实现实时地监护胎儿的健康情况,移动互联网技术和医疗技术的结合为这种居家监护模式带来了可能。本文针对孕妇监测宫缩和胎心率以确认胎儿是否处于正常状态的刚性需求,设计并实现了一套更加便携式的居家的可持续监控胎心率和宫缩信号的监护系统,由智能硬件监测终端、客户端APP、Web服务器端等部分组成。本文重点设计开发了智能硬件监测终端,能够进行宫缩和胎心率数据处理与算法分析,实现实时居家监测功能。同时还设计开发了配套的客户端APP和Web服务器,能够显示宫缩压力和胎心率曲线产检图,进行云端数据共享等。本文主要完成了如下几个方面的内容:(1)硬件终端电路设计:设计实现了可靠的硬件电路,主要包括宫缩压力和胎心信号采集与预处理电路、MSP430MCU核心控制电路、蓝牙无线传输电路、FLASH存储电路、电源管理电路、显示和语音提醒电路等,降低了信号干扰,实现了可靠信号的采集和预处理。(2)基于MSP430MCU硬件终端程序设计:实现了硬件终端的监护功能,重点设计实现了宫缩处理算法和胎心率处理算法,形成了宫缩监测和胎心监测两个功能子模块。此外还设计了工作模式控制模块、数据存储与处理模块、数据无线发送模块、提示报警模块、低功耗控制模块等,实现了宫缩和胎心数据的分析,存储,处理,诊断结果提示。(3)客户端与服务器端功能设计:客户端主要开发了监测主界面模块、监测数据记录与上传模块、个人中心管理模块等,实现产检图的显示,监测记录保存上传,生成产检报告等。Web服务器端主要设计了登录管理模块、数据保存模块、产检图模块等,实现了云端数据管理,数据保存,宫缩压力曲线和胎心率曲线显示,监测数据结果查询。(4)系统功能验证与临床测试设计:针对系统各个功能模块,设计了相应的验证试验,实现了对硬件终端、客户端APP及Web服务器端功能的可靠性测试。利用临床数据,在Visual C++2010和Matlab平台上进行了大量的测试和仿真实验,不断优化核心处理算法,保证了系统诊断结果的准确性。与合作医院进行了多次的临床测试,不断改进系统,使系统更具临床实用性。本文所设计的基于智能手机的掌上型孕妇居家监护系统,能够使孕妇在家实时地持续性地监测宫缩和胎心率,并参考临床标准给出诊断结果,使孕妇可以随时了解自身和胎儿健康状况;同时还能够与合作医疗机构进行数据共享,对异常情况进一步诊断,真正实现“产检搬回家”的理念。
[Abstract]:Uterine contraction and fetal heart rate are important physiological characteristics during pregnancy, and they are also very important parameters of clinical birth examination. Clinically, uterine contraction and abnormal fetal heart rate are often the symptoms of premature delivery or miscarriage. Through continuous monitoring of uterine contraction and fetal heart rate, the risks of pregnant women and fetuses can be detected in time, and the purpose of preventing premature birth or abortion can be achieved. With the development of science and technology, people have put forward higher demands on the level of medical services. Pregnant women hope that medical monitoring can be more convenient and that the health of the fetus can be monitored in real time. The combination of mobile Internet technology and medical technology has made it possible to monitor uterine contractions and heart rates in order to determine whether the fetus is in a normal state. A more portable and sustainable monitoring system of fetal heart rate and uterine contraction signal is designed and implemented, which is monitored by intelligent hardware. This paper focuses on the design and development of intelligent hardware monitoring terminal, which can process and analyze the data of uterine contraction and fetal heart rate. At the same time, the client APP and Web server are designed and developed, which can display contractive pressure and fetal heart rate curve. In this paper, the following aspects of the content of the hardware terminal circuit design: design and implementation of reliable hardware circuit, It mainly includes uterine contraction pressure and fetal heart signal acquisition and preprocessing circuit, MSP430 MCU core control circuit, Bluetooth wireless transmission circuit flash storage circuit, power management circuit, display and voice warning circuit, etc. The acquisition and preprocessing of reliable signal is realized. The program of hardware terminal based on MSP430MCU is designed. The monitoring function of hardware terminal is realized, especially the algorithm of uterine contraction processing and fetal heart rate processing is designed. Two functional sub-modules, uterine contraction monitoring and fetal heart monitoring, are formed. In addition, a working mode control module, a data storage and processing module, a data wireless transmission module, an alarm module and a low-power control module are also designed. The function design of client and server is realized: monitoring main interface module, monitoring data recording and uploading module, monitoring data recording and uploading module are developed in client. The personal center management module and so on, realizes the display of the birth inspection map, the monitoring record keeping and uploading, and so on. Web server mainly designs the login management module, the data preservation module, the birth inspection chart module and so on, realizes the cloud data management, etc. Data preservation, systolic pressure curve and fetal heart rate curve display, monitoring data results query. 4) system function verification and clinical test design: for each functional module of the system, designed the corresponding verification test, realized the hardware terminal, Using clinical data, a large number of tests and simulation experiments have been carried out on the platform of Visual C 2010 and Matlab to optimize the core processing algorithm. The system has been tested many times with the cooperative hospital, and the system has been improved to make the system more practical. In this paper, a hand-held home monitoring system for pregnant women based on smart phone is designed. It enables pregnant women to monitor contractions and heart rates at home in real time and continuously, and provides diagnostic results with reference to clinical criteria, enabling pregnant women to keep abreast of their own and fetal health status, and to share data with cooperative medical institutions. Further diagnosis of abnormal conditions, the real realization of "birth inspection move home" concept.
