Abstract
The utility model provides an optical fiber sensor-based digestive tract pressure measuring device for medical clinic. The optical fiber-based digestive tract comprises a probe and a host machine which are connected with each other, wherein the inner part of the probe is a hollow cavity and a measuring head is arranged at the front end of the probe; the optical fiber sensor is arranged in the measuring head and comprises a pressure membrane and an optical fiber; a button and a display are arranged on the host machine, and a signal processing device is arranged in the host machine; and the optical fiber is connected with the signal processing device in the host machine by the hollow cavity of the probe. The optical fiber sensor-based digestive tract pressure measuring device has the advantages that the structure is simple, the use is convenient and the measuring result is accurate.
Description
Technical field
This utility model belongs to medical instruments field, relates in particular to a kind of internal medicine based on Fibre Optical Sensor and uses the digestive tract pressure tester.
Background technology
It is a kind of new diagnostic method that proposes of Digestive System Department in recent years that gastrointestinal pressure detects, and is a kind of safe, convenient, the not damaged estimated of a kind of diagnosis that is used to assist digestive tract disease and postoperative function, inspection that diagnosis is high is technological.Simultaneously also be research and the indispensable instrument of understanding digestive tract normal physiological function and pathophysiological change thereof.At present, be to use the porous measuring cell to detect gastrointestinal peristalsis pressure clinically mostly and change, and the porous measuring cell can not be monitored its pressure intuitively,, judge that to the medical worker state of an illness has increased difficulty so detect inaccurately.
The utility model content
To the problem that background technology exists, this utility model provides a kind of internal medicine based on Fibre Optical Sensor to use the digestive tract pressure tester.
For solving the problems of the technologies described above, this utility model adopts following technical scheme.
A kind of internal medicine based on Fibre Optical Sensor is used the digestive tract pressure tester, comprises feeler lever, main frame; Feeler lever links to each other with main frame, and feeler lever inside is provided with gauge head for cavity and its front end; Be provided with Fibre Optical Sensor in the gauge head, Fibre Optical Sensor comprises pressure-sensitive diaphragm, optical fiber; Main frame is provided with button, display, and its set inside has signal processing apparatus; Optical fiber links to each other with the inner signal processing apparatus of main frame through the feeler lever cavity.
When this utility model carries out pressure detecting; A stable light signal is gone into from an end-fire of optical fiber, and the optical fiber other end inserts the inner signal processing apparatus of main frame, when having the feeler lever measuring pressure of gauge head; Being distributed in the inner optical fiber of Fibre Optical Sensor can be out of shape under the effect of pressure; Linear change can take place in the optical signal of inside of optical fibre like this, under the processing of main frame internal signal blood processor, measures digestive system pressure accurately.
Compared with prior art, this utility model is simple in structure, and is easy to use, and measurement result is more accurate, helps medical personnel and diagnoses the state of an illness more exactly.
