阻塞型睡眠呼吸暂停综合征(OSAS)是常见的睡眠类疾病,为满足居家对OSAS进行初步筛查和诊断,该文设计了基于聚偏氟乙烯(PVDF)压电薄膜的鼾声监测系统。可穿戴式的鼾声监测系统包含高灵敏度鼾声传感器、低噪声信号调理电路、嵌入式系统及上位机系统。根据鼾声段和非鼾声段能量差异大的特点,基于短时能量法进行鼾声端点检测算法设计,通过采集的鼾声信号进行算法验证。经测试,系统采集的鼾声信号信噪比高,端点检测平均误差小于0.032 s,准确率达92.6%,满足潜在OSAS患者的筛查要求以及进行康复训练的自我检查,同时可减轻患者筛查和医学多导睡眠图(PSG)检测的负担。 相似文献

目前常用的宫颈癌细胞筛查方法有TBS分类法和细胞DNA定量分析法,TBS分类法主要是观察细胞形态是否发生异常改变;而DNA定量分析法是统计细胞核内的DNA含量是否发生增值,两种方法需要在两张不同的细胞涂片上分别展开.针对此,设计了一种在复合染色的环境下利用多光谱成像技术的宫颈细胞实时筛查系统.该系统实现了在一张细胞涂片上同时使用TBS分类法和DNA定量分析法进行宫颈癌细胞的筛查.其主要评价参数是细胞核内的DNA含量(即DI指数),同时可以观察细胞形态.该系统可以测量各个细胞核的DI值并且获得整个细胞的彩色图像,从而辅助医生对DI值大于2.5的异常细胞进行定位筛查.实验表明,该系统具有快速、准确和高效的特点,敏感性超过95%,克服了涂片质量差、判断阳性率低的缺点. 相似文献

Advances in information technology in the past decade have resulted in a proliferation of clinical information systems dedicated to individual user groups and clinical functional areas. This, in turn, has led to the need for hospital-wide management and integration of information, and has triggered major efforts towards the development of integrated hospital information systems. A framework for developing an integrated regional health telematics system is presented, based on the functional and data integration of federated autonomous information systems. The concept of the patient meta-record is introduced as a central element in achieving integration in terms of content, structure, and access to information resources. Intelligent image management at the level of either a single health care provider (hospital) or a regional health telematics network is addressed and is achieved through event and model-driven strategies enabled by a distributed hierarchical storage management system. Intelligence, in this context, refers to methods of efficient and effective real-time resource management in the timely delivery of health care 相似文献

随着医院信息化建设的深入发展,门诊医疗信息化流程的优化成为改善门诊患者就医体验的关键。普通的门诊检验排队流程在妇幼医疗领域显得不太"人性化",全自动的采血系统把人为工作交予机器完成,智能分配患者队列,让护理人员将更多精力集中在采血本身,是医疗管理理念的提升,将更好地为患者提供一站式服务。文章对此展开了分析。 相似文献

The management of certain types of health care technology requires that the integrity of the technological system (which includes the technology and the capability of the users of the technology) be routinely assessed to ensure that the system is providing accurate information. Proficiency testing of these health care technology systems is important, not only to ensure the integrity of screening and diagnostic processes, but also for ethical and liability reasons. In this paper, it is shown that all of the criteria used to evaluate the accuracy of drug testing are erroneous. Three general types of criterion errors are present: ignoring the sources of false results; using an improper unit of analysis; and improper treatment of incommensurable factors. As a result, these proficiency studies of drug testing technology systems are of dubious value for formation of health policy about drug testing, or for informing clinical decision makers about the probabilities that drug tests will correctly classify specimens 相似文献

The State of New Mexico is proposing to combine existing technology in biomedical instrumentation, telemetry, data handling, and communications, developed for aerospace applications, with new techniques in public health screening, prevention, and emergency medical treatment, to establish an integrated system of health care for people living in remote areas. The system proposed consists of a physician-monitored central control facility communicating with remote site facilities staffed by paramedical personnel of limited training. Instrumentation at the remote sites, together with simplified laboratory test materials, provides information on patient condition which is transmitted to central data processing equipment and displayed for the center duty physician. The proposed system will provide for: a) remote conduct of multiphasic medical screening and identification of existing health needs, b) emergency medical treatment, and c) limited routine medical care and instruction. A major goal of the program is the development of a systems package as an area utility service which could be obtained for any area using methods similar to those for procuring or establishing hospitals, rural electrification, or telephone utilities. 相似文献
