A Low Power Wireless Pulse Oximeter Sensor for Unobtrusive Wearable Applications

描述（由申请人提供）：Koronis生物医学技术公司（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仪。临床仍然需要一种不显眼的脉搏血氧计传感器，这种传感器体积小，可以长时间舒适地佩戴，而无需更换电池或充电。KBT将使用眼睛安全的垂直腔面发射激光（VCSEL）技术来开发下一代尖端脉搏血氧仪。为了便于长期连续脉搏血氧仪监测，必须克服若干技术挑战。为了设计更紧凑的传感器和改进的可穿戴仪器，可能最关键的挑战是开发更节能和低重量的设备。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，不应该妨碍人们的行动。标准手指脉搏血氧仪在许多应用中并不实用，因为它们会干扰正常的日常工作。

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.
