Abstract

The invention discloses a distributed optical fiber measuring device for alimentary tract dynamic detection and an application thereof, and belongs to the technical field of medical equipment. The device includes an optical fiber, an energy transfer device and a protective sleeve, wherein a FBG array is engraved in an optical fiber sensing region, and the energy transfer device corresponds to theFBG one-to-one, the FBG is encapsulated and the protective sleeve is placed on the outer periphery of the fiber and the energy transfer device, and the ends of the protective sleeve are fixedly bonedwith the optical fiber. The invention also discloses an alimentary tract dynamic parameter detection device using the distributed optical fiber measuring device. The distributed optical fiber measuring device for alimentary tract dynamic detection, through energy transfer device and the optical fiber FBG array, aims to convert the radial pressure from the optical fiber sensing region to the grid region axial tension of FBG grating, realizes the change and transmission of the pressure signal to the light signal, and achieves gastrointestinal motility detection; the device size is reduced by small size design. Therefore, the device solves the technical problems of limited measurement accuracy of alimentary tract power detection device and patient suffering caused by too large device size inthe prior art.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a distributed optical fiber measurement device for dynamic detection of digestive tract and its application. Background technique [0002] Gastrointestinal motility disorders are a common type of digestive system diseases in clinical practice. Digestive system diseases include organic lesions and functional disorders. Functional motility disorders account for more than 50%, and more than 70% of early gastric cancers are asymptomatic Or there are only symptoms of gastric motility deficiency such as functional dyspepsia. Middle-advanced gastric cancer often presents symptoms such as loss of appetite, weight loss and fatigue caused by gastric motility disorder. Therefore, monitoring the changes of physiological lesions in gastrointestinal motility disorders is of great significance for the early diagnosis of digestive system diseases and the prevention of mal...
