The principle of advanced swallowing mechanism models

The Advanced swallowing mechanism model is a professional simulation device used for teaching and research. Its principle is based on the highly realistic reproduction of the anatomical structure of the human oral cavity, throat and upper esophagus, as well as the physiological process of swallowing.

The model is designed to real scale and features key structures such as a movable tongue, soft palate, epiglotis, pharynx and esophageal entrance. It simulates the entire process of food mass formation in the oral cavity, pharyngeal advancement and entry into the esophagus through mechanical or electronic control systems. The core principle lies in visualizing the dynamic process of the swallowing action, enabling learners to clearly observe the tongue's push, the closure of the epiglottis, and the coordination mechanism of airway and esophageal diversion. Some advanced models are equipped with transparent visual designs and sensor feedback systems, which can monitor the operation in real time and provide voice or light prompts, thereby helping operators understand the differences between normal swallowing and abnormal swallowing (such as aspiration or delayed swallowing).

Through the application of this model, learners can intuitively master the anatomical and physiological basis of the swallowing mechanism in a safe environment, thereby improving the clinical ability to assess, conduct rehabilitation training and provide nursing intervention for swallowing disorders. The application of this principle holds significant value for both medical education and rehabilitation training.
