Problems solved by technology

[0003] The present invention provides an esophageal varices pressure measuring instrument and its detection method, which can measure the pressure of esophageal varices veins by identifying the shape and pressure changes of esophageal varices pressure measuring air bag by computer system, so as to overcome the existing "esophageal varices pressure measuring instrument". With the deficiency of subjective error caused by artificial vision, it can measure the pressure in the vein of esophageal varices with different degrees of mild, medium and severe

Abstract

A computer visualized method for measuring the pressure of esophageal varicovein includes such steps as introducing an air bag into esophagus by use of electronic gastroscope, recording the deformations of said air bag by a camera head on the front end of electronic gastroscope, transmitting them to computer for tracking the deformation while synchronously transmitting internal pressure change of air bag to the computer, analyzing the relation between the pressure of air bag and the dynamic image of esophageal varicovein pressure amplitude, and measuring the pressure of air bag, which is just the pressure of esophageal varicovein when the pressure amplitude change of esophageal varicovein is relatively stable. Its system is also disclosed.

Description

Technical field: [0001] The invention belongs to the technical field of medical detection instruments, and in particular relates to an esophageal varices pressure measuring instrument and a method for measuring esophageal varices pressure by identifying the shape and pressure change of an esophageal manometry air bag through a computer system. Background technique: [0002] The pressure in esophageal varices is considered to be the most important index to predict the rupture and bleeding of esophageal varices, so it has been paid more and more attention. "American Journal of Medicine" (JAMA, 1951; 147: 570 ~ 571) first reported the direct puncture of esophageal varices for manometry, but venipuncture can easily cause massive bleeding and secondary infection. The British Journal of Gastrointestinal Tract [Gut, 1987; 28(9): 1162-1165] reported a non-invasive balloon manometry of esophageal varices invented by the principle of cuff manometry. The German "Endoscopy" magazine [E...
