A Low Power Wireless Pulse Oximeter Sensor for Unobtrusive Wearable Applications

描述（由申请人提供）：Koronis Biomedical Technology Corporation（KBT）提议开发和评估一种用于长期可穿戴监测的微型超低功率脉搏血氧计。临床上仍然需要一种不引人注目的脉搏血氧仪传感器，该传感器体积小并且可以长时间舒适地佩戴而无需更换电池或充电。 KBT 将使用人眼安全的垂直腔表面发射激光 (VCSEL) 技术来开发这款下一代尖端脉搏血氧计。必须克服一些技术挑战才能促进长期连续脉搏血氧饱和度监测。为了设计更紧凑的传感器和改进的可穿戴仪器，最关键的挑战也许是开发更节能、重量更轻的设备。此外，在可穿戴设备能够在家庭中有效使用之前，它们必须变得不引人注目并且不应该妨碍人们的移动性。标准手指脉搏血氧计对于许多应用来说并不实用，因为它们会干扰正常的日常任务。

DESCRIPTION (provided by applicant): Koronis Biomedical Technology Corporation (KBT) proposes to develop and evaluate a miniature ultra-low power pulse oximeter for long-term wearable monitoring. There continues to be a clinical need for an unobtrusive pulse oximeter sensor that is small and can be worn comfortably for extended periods of time without battery change or recharge. KBT will use eye-safe Vertical Cavity Surface Emitting Laser (VCSEL) technology to develop this next generation, cutting-edge pulse oximeter. Several technical challenges must be overcome to facilitate long-term continuous pulse oximetry monitoring. In order to design more compact sensors and improved wearable instrumentation, perhaps the most critical challenges are to develop more power efficient and low-weight devices. Additionally, before wearable devices can be used effectively in the home, they must become unobtrusive and should not hinder a person's mobility. Standard finger pulse oximeters are not practical for many applications because they can interfere with normal daily tasks.
