Wearable medical devices can provide both continuous monitoring and ubiquitous treatment. Challenges in this area include the need for a low-power/power-saving design to extend battery life and to reduce the size of the battery itself. This is followed by size and weight restrictions to meet patient expectations of what is 'wearable', the biocompatibility of all outer housings and the final assembly concept. Two examples of wearable medical device are described: a wrist-wearable telemedicine monitor for heart patients (AMON) and a generic belt-integrated computing platform for home and hospital use (QBIC). The electrocardiogram (ECG), the blood oxygen saturation (SpO2) sensor and the blood pressure meter of the AMON device were tested with 29 subjects. The sensors were found to be functional, but as expected the data processing algorithms will need some fine-tuning. The prototype QBIC demonstrates a size reduction of 30-50% in relation to comparable devices.
可穿戴医疗设备能够提供持续监测和普遍治疗。该领域面临的挑战包括需要进行低功耗/节能设计，以延长电池寿命并减小电池本身的尺寸。其次是尺寸和重量限制，以满足患者对“可穿戴”设备的期望，所有外壳的生物相容性以及最终的组装概念。文中描述了两款可穿戴医疗设备的示例：一款用于心脏病患者的腕戴式远程医疗监测器（AMON）和一款用于家庭及医院的通用腰带集成计算平台（QBIC）。AMON设备的心电图（ECG）、血氧饱和度（SpO2）传感器和血压计在29名受试者身上进行了测试。结果发现这些传感器功能正常，但正如预期的那样，数据处理算法还需要进行一些微调。QBIC原型展示出与同类设备相比尺寸减小了30%至50%。
