光纤传感器在人体内压力监测中的效应

Fiber optical sensor effectiveness in the human body

背景:人体内压力尤其是食道曲张静脉压力监测是近年来研究的热点,光纤传感器在人体内压力监测方面取得了较大的进展。目的:综述光纤传感器在人体内压力监测中的应用。方法:以"光纤传感器,压力,测量;fiber optical sensor,pressure,measurement"为检索词,应用计算机检索中国学术期刊全文数据库CNKI和PubMed数据库1983年1月至2013年3月有关光纤传感器测压的文章。排除与研究目的无关和内容重复文献,保留40篇文献做进一步分析。结果与结论:与传统传感器相比,光纤传感器具有灵敏度高、动态范围大、响应速度快、不受电磁干扰、防爆防燃、防腐蚀等优点,已被用于食道静脉曲张压力、颅内压、咽部压力、小儿气管内压力、心血管及血液压力、椎间盘压力、分娩时子宫内压力、结肠内压力、足底压力和剪切力等人体压力的测量。可见光纤传感器在医学中压力监测方面的应用越来越广泛,相信随着制作技术的成熟和器件性能的不断提高,不久的将来光纤传感器将会进一步推动医学的快速发展。

BACKGROUND： In recent years, monitoring the pressure in the human body, especially esophageal variceal pressure, becomes a hot spot. A lot of progress has been achieved regarding fiber optical sensors for measurement of the pressure in the human body.OBJECTIVE： To briefly review the fiber optical sensor applications in the human body.METHODS： A computer-based online retrieval was performed to search papers in CNKI periodical full-text database and PubMed database（from January 1983 to March 2013） using the key words of ＂fiber optical sensor,pressure, measurement＂ in Chinese and English, respectively. After excluding objective-independent and repetitive papers, 40 papers were included for further analysis.RESULTS AND CONCLUSION： Compared with traditional sensors, fiber optical sensors, which have advantages in high sensitivity, large dynamic range, fast response, tolerance to electronic interference, explosion proofing, fireproofing and corrosion protection, have been used to measure esophageal variceal pressure,intracranial pressure, pharyngeal pressure, pediatric airway pressure, cardiovascular blood pressure,intervertebral disc pressure, intrauterin pressure in childbirth, pressure in the colon, plantar pressure and shear force as well as other pressures in the human body. Fiber optical sensors have been used more widely in pressure monitoring.With the development of production technology and device performance, fiber optical sensors will further promote the rapid development of medical science in the near future.
