A Low Power Wireless Pulse Oximeter Sensor for Unobtrusive Wearable Applications

描述（由申请人提供）：Koronis Biomedical Technology Corporation（KBT）拟开发和评估一种用于长期可穿戴监测的微型超低功耗脉搏血氧仪。临床上仍然需要一种不显眼的脉搏血氧计传感器，该脉搏血氧计传感器体积小，并且可以在不更换电池或充电的情况下舒适地佩戴较长时间。KBT将使用人眼安全的垂直腔面发射激光器（VCSEL）技术来开发这种下一代尖端脉搏血氧仪。必须克服几个技术挑战，以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，也许最关键的挑战是开发更节能和重量更轻的设备。此外，在可穿戴设备可以在家中有效使用之前，它们必须变得不显眼，并且不应该妨碍人的移动性。标准的手指脉搏血氧仪对于许多应用来说是不实用的，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.
