飞思卡尔让医疗电子无处不在

世界卫生组织资料显示,到2020年,全球超过60岁以上的老年人口将比2000年增加一倍。全球人口老龄化问题直接影响各国的医疗保健支出,在经济较为发达的美国和欧洲地区,医疗保健花费约占GDP的15%,可达万亿美元数量级,以美国为例:2007年美国的医保支出达2万亿美元,而随着人口老龄化趋势,预计2012年,全美的医保支出将达到3.1万亿美元。此外,生活水平的提高使得人们对于增进健康照顾的期望持续增加。这些都使得医疗保健的支出处于持续增长状态。     

医疗电子应对小型化挑战

健康无疑是世人的首要追求,而医保费用向来也不是可以自由支配的开支。能够负担得起的人固然会继续支付这方面的费     

顺应便携式医疗保健应用的需求

两种趋势影响着医疗和工业设备设计人员:一是便携性,二是此类设备越来越多地用于消费和实验室应用。血糖监控仪、多参数血液分析仪、脉搏血氧仪、PH计和环境监控仪就是其中的例子,这些设备一度仅存在于

Instrumentation for Health Care

Engineers, pragmatic and ``action'-oriented, are indispensable principal members of the health-care team. The primary role of the biomedical engineer is to provide the conceptual and material tools required to perform medical tasks, i.e., instrumentation for health care.     

Technology in Health Care

Many elements for the construction of a health delivery system now exist but they are spotty and diffused. Much effort has been concentrated on primary care affecting 10 percent of the people but ? of the costs of the system. Little attention has been paid to the other elements-prevention, protection, tertiary care, and rehabilitation, although these may eventually have greater effectiveness in improving the system as a whole. Attempts must now be made to combine disparate elements into a total system of health care by interfacing the modular components from several subsystems into a single unit.     

Standardization and Health Care

In order to deliver reasonable health care to all people, it is essential that standards be established. Standards vary with the type of control and with the approach desired in determining the quality of care. This paper discusses various kinds of standards and their application in the health care field. Standards may be determined as a process or as a direct regulation. It is probable that regulation of standards by process is the most satisfactory method.

Value-Sensitive Design and Health Care in Africa

In this paper, we describe our approach of using value-sensitive design to guide the design, development, and implementation of health information systems for use in rural areas of two developing countries in Africa. By using shared conceptual investigation, we are able to create a generalized list of stakeholders and values that span multiple projects without losing any of the power of the conceptual investigation. This process can be applied to other projects to develop a stronger set of stakeholders and values. We also present a technical investigation of a vaccine delivery project in Sub-Saharan Africa and plans for an upcoming empirical investigation for a mobile-phone-based support tool for community health workers in East Africa.
