DEVELOPMENT OF A FIBER OPTIC GASTRIC PH SENSOR

一种光纤pH传感器以及相关的仪器正在 开发用于测量和监测食管内和 胃内pH。由可更换传感器、光学系统和 电子电路，仪器应该能够测量pH值在 范围为0-7，精度为0.1 pH单位，响应时间为 范围为30秒，长达24小时。 这个工具应该有用 用于研究、诊断和评估酸相关疾病， 上消化道，以及研究 饮食和抗分泌药物。

A fiber-optic pH sensor, as well as associated instrumentation, is being developed for measurement and monitoring of intraesophageal and intragastric pH. Composed of replaceable sensors, an optical system, and electronic circuitry, the instrument should be able to measure pH in the range of 0-7, with an accuracy of 0.1 pH units and a response time in the range of 30 sec, for up to 24 hours. This instrument should be useful for the research, diagnosis, and evaluation of acid-related disorders of the upper gastrointestinal tract, and for studies on the influence of diet and antisecretory drugs.
