Non-Invasive Telemetric Sensing for Lower Leg Amputee Surface Skin Management

截肢不仅发生在事故或战争之后，现在主要是作为糖尿病的并发症发生，继而是溃疡和坏疽。截肢后佩戴假肢有助于社会和经济活动和包容，但近75%的腿部截肢者会经历皮肤并发症，这可能导致放弃假肢，进而可能导致二次截肢，甚至死亡。随着糖尿病在全球范围内的增加，个人和社会的负担越来越大，但及早认识到皮肤变化可能会引发预防行动。为了解决这个问题，Bioflex Yarns和PST Sensors Europe联手开发了一种肢体监测系统，以被动热调节、生理参数非侵入性监测和基于物联网的数据分析方面的“尖端”技术为基础，对皮肤并发症进行警报。这项技术的核心是智能假肢袜子，它穿起来和传统的假肢袜子一样舒服。截肢者手机上的一款应用程序会在问题开始时发出警报。个人截肢者将拥有个人信息，直接参与护理，并改变日常生活体验。此外，由于指定医疗队可以直接获取临床信息，因此任何适当的干预都可以是及时和具有成本效益的。多患者截肢者数据库平台可以允许NHS分配资源，为截肢者提供有针对性的护理，以降低医疗保健成本。

Lower limb amputations not only occur following accidents or war, but now predominantly occur as a complication of diabetes, following ulceration and gangrene. Wearing a prosthesis following amputation facilitates social and economic activity and inclusion, but nearly 75% of leg amputees experience skin complications, which can result in abandoning the prostheses, and may in turn lead to secondary amputation, and even death. With the world-wide increase in diabetes, there is an increasing burden for the individual and for society, but early recognition of skin changes could trigger preventative action. To address this problem, Bioflex Yarns and PST Sensors Europe have joined forces to develop a limb monitoring system to alert for skin complications, to be based on 'cutting-edge' technologies in passive thermal regulation, non-invasive monitoring of physiological parameters, and IoT based data analysis. At the centre of the technology is the smart prosthesis sock, which is as comfortable to wear as a traditional prosthesis sock. An app on the amputee’s mobile phone alerts when problems commence. The individual amputee will have personal information, direct involvement in care, and a transformed daily living experience. Furthermore, with the clinical information directly accessible to the designated medical team, any appropriate intervention can be timely and cost effective. The multi-patient amputee database platform can allow the NHS to allocate resources to provide targeted care to amputees, for reduced health care costs.
