医疗输液呼叫设备研究与设计

目前很多医院病人输液呼叫依赖于病人或者病人家属以及医护人员,这很大程度依赖于病人及家属的主观注意力以及医护人员的输液管理,会经常出现点滴打完没有及时呼叫和处理的情况,这具有一定风险,会给病人及家属增加负担和压力,同时也给医生和护士带来麻烦。本文对医生、病人及家属的需求进行分析,研究设计一款计算机控制的医疗输液呼叫设备,进而很好地解决这一问题。     

医院无线呼救系统

基于无线传输方式,本文提出一种无线呼救系统,旨在解决一些不方便搭建有线呼叫系统的医院急救问题。该系统由病床模块、护士模块和护士站模块组成。三部分之间的数据传输均采用无线通信的方式。由于比一般的系统增设了护士模块部分,因此可以将病人的呼叫信息及时传递给护士,以避免因巡房等因素造成的"时间空白"。本文中着重对该系统的呼叫功能及其软件设计进行了介绍。     

病房数显呼叫器

病房数显呼叫器如附图所示,可实现病房和值班室之间双向传递信息的功能。病房中安装按钮开关K0-K9和发光二极管D0-D9,将数码管和蜂鸣器安装在护士值班室。没有病人呼叫时蜂鸣器不叫,数码管熄灭。病人按下开关K2时,值班室的蜂鸣器报警并使数码管显示2;同时装在病房中的发光二极管点亮,提示病人信号已传送到值班室。只有按下装在值班室内的开关才会使数码管熄灭、蜂鸣器停止呼叫;同时也熄灭装在病房中的发光管,以便告诉病人值班人员已经知道某号病人     

医疗点滴输液监测系统数据中心节点设计

医疗点滴输液监视系统用于对医院病人点滴输液过程进行监视.当输液状况异常时,系统进行报警以提示护士去处理.该系统包括无线终端(WED)、数据中心结点(AP)和上位机监视软件三个部分.无线终端用于检测每个病床的点滴输液状态.本文主要描述数据中心结点AP的设计与实现.数据中心结点以TI公司的无线单片机芯片CC2510为核心,接收无线终端采集的点滴输液状态信息,处理后存入SD卡备份,并发送给上位机,以便护士在护士站上位机集中监视各个病人的输液状态.

XY·CN总线供电及通信系统(连载)——基于XY·CN总线的医院呼叫系统

呼叫系统是医院重要的监控系统之一。一套好的呼叫系统可以使患者得到及时的救助,提高护士的工作效率,更重要的是能记录护士的工作状况,为人力资源管理提供第一手资料。目前应用较多的呼叫系统是分线制呼叫系统,它具有设备简单、成本较低的优点,但其并联结构布线复杂、功能单一。无线呼叫系统具有不用布线、安装方便、可随身携带的优点,但设备成本高、功能单一,且需要经常更换电池、通信穿透力差,可靠性没有保证。本文以XY.CN总线在该系统的应用为主线,介绍XY.CN总线具体应用方案的实现。1系统方案设计1.1系统框图一级XY.CN总线完成一个护士值班室管辖范围内的设备管理工作。二级XY.CN总线完成护士应答处理器的信息网络记录及紧急呼叫医生的工作。图1基于XY.CN总线医院呼叫系统1.2流程说明患者求助。患者呼叫通过呼叫对讲器完成,XY.CN总线具有快速反应的功能,患者呼叫在80ms之内就会在护士应答处理器上生成音频及视频报警,并指示该患者的床位号及患者名称等信息。②护士应答处理。护士收到求助后,控制接通与患者的音频电话系统,了解求助问题并携带必备物品进行处理。护士在求助处理完成后,在呼叫对讲器上按键或提供IC卡进行身份识别的处理完...

Building a Distributed E-Healthcare System Using SOA

This article describes a distributed e-healthcare system that uses the service-oriented architecture as a means of designing, implementing, and managing healthcare services. Medical monitoring devices worn by the patient, and frequent electronic communication between the patient and a nurse, can ensure that the prescribed treatment is being followed and that the patient is making good progress. The e-healthcare system described here can be readily extended to other healthcare professionals, including medical technicians who perform and report tests and analyses requested by physicians. In addition, the system can be interfaced to other applications that provide information on medications and dosages and warn of interactions between medications. Finally, it can be interfaced to drug-delivery devices that prompt and monitor the regular and timely consumption of medications.

Design and evaluation of a wireless decision-support system for heart rate variability study in haemodialysis follow-up procedures

In this paper a new wireless decision-support system for haemodialysis patients using heart rate variability (HRV) is presented. The telemedicine system provides connectivity to three participant sites: the general practitioner or nurse at the point of care in the dialysis unit, the remote information and processing server and the cardiologist. At the clinical point of care, the nurse acquires the electrocardiogram (ECG) by using a tailored mobile telecardiology system as well as other relevant physiological information during the clinical procedure, and sends it to the information server. The received information is stored in a secure file server, linked to the patient database and the ECG signal is automatically analyzed by using advanced signal processing tools in the processing server, where a complete clinical results report is generated. The cardiologist can then be linked by means of a web browser to the information server to analyze these results for further clinical diagnosis support. The system has been applied to study HRV in patients undergoing haemodialysis. The clinical report consisted of trends for time- and frequency-domain HRV indexes and other supplementary information automatically calculated, which show the response of the electrical activity of the heart to the dialysis process and that can be helpful for the follow-up of these patients. The telecardiology framework has been successfully evaluated both by the patients and the hospital personnel showing a high compliance with the system. The design and implementation of the telecardiology system have followed the most recent advances in web technologies, biomedical information and storage standards and signal processing techniques. The presented system can be used as a telemedicine tool for clinical diagnosis support and could also be used in other clinical settings.

Nurse staffing: Accurate information at the correct place and time

Nurse Staffing at this 300 bed acute care hospital is based on the results of calculations of patient care needs performed two hours before the beginning of each shift. This allows the central nurse staffing office to balance staffing levels with patient care needs. Forms and procedures are designed so that the quantification of patient care needs is a result of completing a redesigned patient care plan. The patient care needs are translated into a number (acuity points) and recorded onto a preprinted census sheet. This sheet is sent to a central nurse staffing office during the middle of each shift. The nurse staffing office enters the acuity points by patient room number into a microcomputer. The data is then processed into a report that compares the hours of care needed by nursing unit with the actual hours available. This report is available two hours before the next shift begins, allowing the nurse staffing department to adjust staff assignments based on patient care needs. The nurse staffing clerk also updates the data after changes have been made in staff assignments. This provides accurate historical data which is summarized for productivity and budget calculations. The unique combination of the hospitals main computer, redesigned patient care plan, pneumatic tube, and microcomputer have solved a major nurse staffing problem by providing information in an accurate and timely fashion. The program has been in existence since August, 1984. In a time of lower hospital utilization this system has allowed the hospital to control its nursing resource and avoid layoffs. The microcomputer programs where written by the author using the programming language BASIC.     

基于语义分割的红外和可见光图像融合

红外图像即使在低光照条件下,也能根据热辐射的差异将目标与背景区分开来,而可见光图像具有高空间分辨率的纹理细节,此外,红外和可见光图像都含有相应的语义信息.因此,红外与可见光图像融合,需要既保留红外图像的辐射信息,也保留可见光图像的纹理细节,同时,也要反映出二者的语义信息.而语义分割可以将图像转换为带有语义的掩膜,提取源图像的语义信息.提出了一种基于语义分割的红外和可见光图像融合方法,能够克服现有融合方法不能针对性地提取不同区域特有信息的缺点.使用生成式对抗神经网络,并针对源图像的不同区域设计了2种不同的损失函数,以提高融合图像的质量.首先通过语义分割得到含有红外图像目标区域语义信息的掩模,并利用掩模将红外和可见光图像分割为红外图像目标区域、红外图像背景区域、可见光图像目标区域和可见光图像背景区域;然后对目标区域和背景区域分别采用不同的损失函数得到目标区域和背景区域的融合图像;最后将2幅融合图像结合起来得到最终融合图像.实验表明,融合结果目标区域对比度更高,背景区域纹理细节更丰富,提出的方法取得了较好的融合效果.
