光纤压力传感器在医疗领域的发展及应用

Development and Application of Fiber-optic Pressure Sensor in Medical Field

人体内压力监测对检查器官或组织病变、实时分析术中情况起着十分重要的作用。相对于传统的机电式压力传感器,光纤压力传感器具有体积小、灵敏度高、安全性高、抗电磁干扰能力强等优势,在医疗领域得到了广泛的应用。该文综述了光纤压力传感器的发展历程及在医疗领域压力监测中的应用。重点分析了光纤压力传感器在心血管及血液、颅内、气道、胃肠道等组织或器官内的压力监测。分析表明,光纤压力传感器在不同的组织或器官内均可以达到良好的监测效果。

In vivo pressure monitoring is important for monitoring of organ or tissue lesions and real-time analysis of intraoperative conditions. Compared with the traditional electromechanical pressure sensor, the optical fiber pressure sensor has the advantages of small size, high sensitivity, high safety and strong ability of resisting electromagnetic interference. It has been widely applied in the medical field. This thesis reviews the development of optical fiber pressure sensors and the application of pressure monitoring in the medical field. It emphatically analyses the monitoring of the optical fiber pressure sensor in cardiovascular and blood, intracranial, airway, gastrointestinal tract and other tissues or organs. Analysis shows that the favorable result of monitor can be got using optical fiber pressure sensor in different tissues or organs.
