Display model of otolithiasis occurrence and reduction treatment mechanism

Abstract

The invention relates to the field of medical teaching models, in particular to a display model of an otolithiasis occurrence and reduction treatment mechanism, which comprises a front semicircular canal, a rear semicircular canal, a horizontal semicircular canal and an elliptical capsule, water flow direction sensors are arranged at the front end of the front semicircular canal, the front end of the rear semicircular canal and the front end of the horizontal semicircular canal, blocking nets are arranged at inlets and outlets of the water flow direction sensors, and the water flow direction sensors are electrically connected to the same control box. The control box is provided with an excitation signal lamp and a suppression signal lamp which are arranged corresponding to the front semicircular canal, the rear semicircular canal and the horizontal semicircular canal. According to the invention, the condition that the fallen otolith rolls in the lost way of the inner eardrum under the action of gravity is simulated, so that the morbidity of the otolithiasis and the manual reduction treatment process are simulated, and the display model is used for medical clinical teaching and science popularization display, so that viewers can better understand the morbidity and treatment mechanism of the otolithiasis.

Description

technical field [0001] The invention relates to the field of medical teaching models, in particular to a display model of the occurrence and reset treatment mechanism of otolithiasis. Background technique [0002] Benign paroxysmal positional vertigo is the most common clinical vertigo disease. The pathogenesis of the disease is that the otoliths in the inner eardrum labyrinth fall off, enter the semicircular canal and roll with gravity, resulting in vertigo symptoms that change relative to the gravity of the head position. The disease is currently It is recognized that the most effective treatment method is to turn the head in a specific direction and angle, and use the effect of gravity to roll the otolith back into the utricle, and the vertigo symptoms will disappear. [0003] Because the structure of the labyrinth of the inner ear is very complex, it takes a long time and lectures to fully understand the process of otoliths rotating by gravity in the labyrinth of the inn...
