FIBER OPTIC PROBES

需要一种合适的装置来直接测量氧分压。 用于临床和研究的血液和组织中的压力(PO2) 申请。目前可用于测量P02缺损量的方法 方便性、可靠性、速度和对多种情况的适用性 利息。开发电子传感器的努力并未取得成功。 希望有一种非常小的P02传感器，它可以插入到 血管或组织几乎没有干扰，这将提供 短时间或长时间的瞬时P02监测。 光纤传感器是这种应用的理想选择，具有以下优点 生理用途的，体积很小，灵活，安全，低 成本。根据P02传感器的工作原理，研制了一种P02传感器 荧光被氧猝灭。该传感器的可行性及其应用 在体外和体内的测试中都证明了令人满意的性能。 在过去的几年里。针形传感器的研制 进行了探头，研制出了适合研究应用的仪器。 发展起来的。

A suitable device is needed for the direct measurement of oxygen partial pressure (PO2) in blood and tissue for both clinical and research applications. Methods currently available for measuring P02 lack convenience, reliability, speed, and applicability to many situations of interest. Efforts to develop electrical sensors have not been successful. It is desirable to have a very small P02 sensor that can he inserted into a blood vessel or tissue with little disturbance, which will provide instantaneous P02 monitoring for either short or extended periods of time. A fiber-optic sensor is ideal for this application, with the advantage, for physiological use, of very small size and flexibility, safety, and low cost. A P02 sensor has been developed, based upon the principle of fluorescence quenching by oxygen. The feasibility of the sensor and its satisfactory performance have been demonstrated in vitro and in vivo tests in preceding years. The development of the sensor in the form of a needle probe was done, and an instrument suitable for research applications was developed.
