描述(申请人提供)：先进医疗电子公司(AME)和我们的合作伙伴提出了一种微创系统，用于校准和重复测量周围组织的氧合。提出了一种基于第三代聚芳基甘氨酸树枝修饰的Pd-四苯并卟啉表面涂覆一层聚乙二醇膜的光耦合氧烷微传感器方法。特氟隆AF室将被用来隔离与身体接触的氧磷溶液，该系统通过磷光猝灭提供氧压测量。传感器的响应时间估计不到一分钟，稳定性超过16小时。该方法的优点包括坚固、快速插入和具有绝对校准的最小侵入性设备。在第一阶段，将指定、开发和评估原型系统。

英文摘要

DESCRIPTION (provided by applicant): Advanced Medical Electronics (AME) and our partners propose a minimally-invasive system for calibrated and repeatable measurement of peripheral tissue oxygenation. An optically coupled oxyphor-based micro-sensor approach is proposed based on Pd-tetrabenzoporphyrin modified with generation-3 polyarylglycine dendrons and coated with a layer of polyethylene glycol. Teflon AF chambers will be utilized to sequester the Oxyphor solution from contact with the body and the system provides a measurement of oxygen pressure by phosphorescence quenching. Sensor response time is estimated to be less than one minute with stability for greater than 16 hours. Advantages to the approach include a robust, quickly inserted and minimally invasive device with absolute calibration. In phase 1, a prototype system will be specified, developed, and evaluated.
