RESUMO
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.
