【摘要】：随着信息化技术的发展,医疗领域开始朝着智能化的方向快速升级。同时医疗机构也开始关注在服务方面的改善,提升病人就医体验。其中住院病房是病人较长时间所处的区域,是医院提升服务的重点关注方向。病房的呼叫系统作为连接住院病人和医护人员的桥梁起着至关重要的作用,目前呼叫系统已经开始从有线方式向无线方式转变。本文设计了一套基于EnOcean无线技术的可佩戴病房呼叫系统,包括有呼叫器终端、网关、数据库和监控端应用程序四部分。呼叫器终端采用的无线方案是EnOcean无线技术,通过采集机械能量的方式为射频模块提供电能,主要由能量采集模块ECO200和射频模块PTM330组成,使用频段为868MHz。当按动呼叫器时,射频模块会发出无线报文信号,被所处区域的网关接收。网关是由树莓派开发板和EnOcean收发射频模块TCM310组成,在接收到呼叫器的无线信号后,先通过ESP协议程序解析,检测是否为符合要求的呼叫请求,之后通过基于TCP/IP的网络将请求信息上传至数据库和监控端应用程序。数据库采用MySQL建立,存放所有呼叫器终端和网关的硬件信息,以及病人信息和呼叫请求记录。监控端程序主要完成设置功能和响应呼叫请求,可添加或删除呼叫器终端和网关的ID,录入病人信息并分配呼叫器等。图形界面使用PyQt4编写,其他功能代码使用Python语言实现。通过分析我国医院病房现状,设定了系统的部署方案,确定了在有障碍物情况下呼叫器的信号室内可接收范围至少达到9.5米以上。经过测试,网关的信号接收范围实际可以达到覆盖六间六人制病房的空间需求。本呼叫系统具有使用简单,易安装部署、呼叫器无源免维护等特点,在医疗机构、养老院等场所有应用价值。
[Abstract]:With the development of information technology, the medical field begins to upgrade rapidly in the direction of intelligence. At the same time, medical institutions are also focusing on the improvement of services to enhance patient experience. The inpatient ward is the area where the patients live for a long time, and is the focus of the hospital promotion service. As a bridge between hospitalized patients and medical staff, the call system of the ward plays an important role. At present, the call system has begun to change from wired mode to wireless mode. A wearable ward call system based on EnOcean wireless technology is designed in this paper, which includes four parts: pager terminal, gateway, database and monitor application. The wireless scheme used in the pager terminal is EnOcean wireless technology. The radio frequency module is mainly composed of the energy acquisition module (ECO200) and the radio frequency module (PTM330), which provides electrical energy for the RF module by collecting mechanical energy. The frequency band is 868 MHz. When the pager is pressed, the radio-frequency module sends out the wireless message signal and is received by the gateway in the region. The gateway is composed of raspberry pie development board and EnOcean radio frequency module TCM310. After receiving the radio signal of the pager, the gateway is resolved by the ESP protocol program to detect whether it is a call request that meets the requirements. Then the request information is uploaded to the database and monitor application through the TCP/IP-based network. The database is set up by MySQL, storing the hardware information of all pager terminals and gateways, as well as patient information and call request record. The monitoring program mainly completes the function of setting up and responding to the call request. It can add or remove the IDs of the pager terminal and gateway, input the patient information and distribute the pager, etc. The graphical interface is written by PyQt4, and other functional codes are implemented by Python language. By analyzing the present situation of hospital wards in our country, the system deployment scheme is set up, and the reception range of the pager in the room with obstacles is determined to be at least 9.5 meters or more. After testing, the signal receiving range of the gateway can meet the space requirement of the six-person ward. The call system is easy to use, easy to install and deploy, pager passive maintenance and other features, in medical institutions, nursing homes and other places of application value.
