描述（由申请人提供）：Advanced Medical Electronics（AME）和我们的合作伙伴提出了一种微创系统，用于外周组织氧合的校准和可重复测量。提出了一种基于光耦合氧传感器的微传感器方法，该方法基于用第三代聚芳基甘氨酸树枝状分子修饰的Pd-四苯并卟啉，并涂覆有一层聚乙二醇。将使用Teflon AF室隔离Oxyphor溶液，使其不与身体接触，系统通过磷光淬灭提供氧压测量。传感器响应时间估计小于1分钟，稳定性超过16小时。该方法的优点包括具有绝对校准的鲁棒、快速插入和微创设备。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.
