Space tech for remote monitoring eases Covid-19 pressure
Covid-19的第二波浪潮是再次在压力下看到急诊室和重症监护病房。床不足，医院发生交叉感染的风险正在增加，容量水平已经达到关键阶段。
So doctors at Luigi Sacco University Hospital in Milan are testing a system that monitors Covid-19 patients’ vital signs remotely using a chest belt initially developed at CSEM in Switzerland for space applications. A wireless Covid-19monitoring systemis also being tested by Philips at a hospital in the Netherlands.
COMO系统在A中使用干电传感器CSEM-designed chest belt that take continual readings of a patient’s heartbeat, breathing rate and body movements. The system also includes wireless devices that periodically measure the patient’s blood oxygen-saturation levels (SpO2) and skin temperature.
测量值通过安装在患者智能手机上的应用程序发送到中央系统；然后，医生可以查看数据并监控患者的病情。如果患者的读数之一脱离了预设阈值范围，则该系统可以向医疗团队发送通知。有了这个系统，患者可以待在家里，并在需要时接受个性化的医疗和心理护理。
该系统目前正在米兰的路易吉萨科大学医院进行临床试验，该平台已获得伦理委员会的批准。
“我对可靠性和精确度方面的技术内容感到非常满意，并为最终可以使用一种选择的工具而是一种有效的治疗工具的患者感到高兴，”董事毛里齐奥·维斯卡（Maurizio Viecca）博士说。心脏病学。

资金来自ESA和意大利航天局（ASI），因为它使用了CSEM最初为ESA开发的技术，以在南极洲Concordia研究基础的研究探险期间对生理参数进行测量。
CSEM had also improved the sensing technology to make it compatible with conditions in the International Space Station, so that it can monitor astronauts. Now the technology has been updated through the R&D partnership with Vexatec.
“ ESA的计划旨在支持通过我们的各种太空任务和研究项目开发的知识和技术的创新产品和服务的开发和营销，”负责ESA COMO项目的Elena Razzano和Arnaud Runge说。他们补充说：“如果我们可以重新部署与空间有关的研究以帮助挽救生命，我们将感到高兴。”
The belt contains two sensors on each side that are placed directly on the patient’s skin. Each sensor contains all the electronics needed for signal processing. The data are sent to the patient’s smartphone via Bluetooth and subsequently to a cloud platform where the patient’s health-care team can view them. A smartphone app is also available for doctors.
CSEM项目负责人Pascal Heck说：“我们的系统可以执行心脏病专家可以直接使用的精确心电图。”Como的另一个优点是，它采用了干电极传感器，这些传感器更舒适，可以使患者穿着更容易去除，例如患者想洗个澡。“ ECG中通常使用的电极具有粘合剂，会刺激皮肤。我们决定使用由不锈钢制成的干电极，然后开发必要的电子设备，以达到与医生在诊所中获得相同的信号质量，但对患者的刺激性较小。” Heck说。
Vexatec计划根据这项开发工作的结果来销售新系统。
“Our system has a lot of advantages for medical monitoring in general and for remote health care,” says Urs Ruggaber, CEO of Vexatec. “We are developing a new generation of sensors and aim to launch them next year.”
