Description
技术领域 technical field
本实用新型属于医疗器械领域，尤其涉及一种基于光纤传感器的内科用消化道测压装置。 The utility model belongs to the field of medical instruments, in particular to a digestive tract pressure measuring device for internal medicine based on an optical fiber sensor.
背景技术 Background technique
消化道压力检测是近年来消化内科提出的一种新的诊断方法，是一种用于协助消化道疾病的诊断及术后功能评价的一种安全、方便、无损伤、诊断率高的检查技术。同时也是研究及了解消化道正常生理功能及其病理生理改变的不可缺少的工具。目前，临床上大多是使用多孔测压仪来检测胃肠蠕动压力变化，而多孔测压仪不能直观地监测其压力，所以检测不准确，给医务人员判断病情增加了难度。 Gastrointestinal pressure testing is a new diagnostic method proposed by the Department of Gastroenterology in recent years. It is a safe, convenient, non-invasive, and high-diagnostic technique used to assist in the diagnosis of gastrointestinal diseases and postoperative functional evaluation. . It is also an indispensable tool for studying and understanding the normal physiological functions of the digestive tract and its pathophysiological changes. At present, most of the clinical practice is to use porous manometry to detect the change of gastrointestinal motility pressure, but the porous manometry cannot monitor the pressure intuitively, so the detection is inaccurate, which makes it more difficult for medical staff to judge the condition.
实用新型内容 Utility model content
针对背景技术存在的问题，本实用新型提供一种基于光纤传感器的内科用消化道测压装置。 Aiming at the problems existing in the background technology, the utility model provides a digestive tract pressure measuring device for internal medicine based on an optical fiber sensor.
为解决上述技术问题，本实用新型采用如下技术方案。 In order to solve the above technical problems, the utility model adopts the following technical solutions.
一种基于光纤传感器的内科用消化道测压装置，包括探杆、主机；探杆与主机相连，探杆内部为空腔且其前端设置有测头；测头内设置有光纤传感器，光纤传感器包括压力膜片、光纤；主机上设置有按键、显示器，其内部设置有信号处理装置；光纤通过探杆空腔与主机内部的信号处理装置相连。 An internal medicine digestive tract pressure measuring device based on an optical fiber sensor, comprising a probe rod and a host; It includes a pressure diaphragm and an optical fiber; the host is provided with buttons and a display, and a signal processing device is arranged inside; the optical fiber is connected with the signal processing device inside the host through the cavity of the probe rod.
本实用新型进行压力检测时，将一个稳定的光源信号从光纤的一端射入，光纤另一端接入主机内部的信号处理装置，当带有测头的探杆测压力时，分布在光纤传感器内部的光纤会在压力的作用下变形，这样光纤内部的光信号会发生线性变化，在主机内部信号处理装置的处理下，准确的测出消化系统压力。 When the utility model performs pressure detection, a stable light source signal is injected from one end of the optical fiber, and the other end of the optical fiber is connected to the signal processing device inside the host. The optical fiber will deform under the action of pressure, so that the optical signal inside the optical fiber will change linearly, and the pressure of the digestive system can be accurately measured under the processing of the signal processing device inside the host.
与现有技术相比，本实用新型结构简单，使用方便，测量结果更加准确，有利于医护人员更加准确地诊断病情。 Compared with the prior art, the utility model has the advantages of simple structure, convenient use and more accurate measurement results, which is beneficial for medical staff to diagnose the disease more accurately. the
