The first robotic simulation of pharyngeal swallowing
- 3D model of human larynx – scale 1:1
- Mobility of each component of pharyngo-laryngeal apparatus
- Swallowing events can be precisely controlled by acting on pre-programmed chronograms
- Accurate displacement system mimics features such as:
- Tongue base recoil
- Laryngeal elevation
- Peristaltic pharyngeal movement
- Epiglottis closure of larynx
- Vocal fold adduction
- Respect of the chronological order of physiological events
- Each component can be separately controlled from a specific interface
- Accurate observation by dual high-speed synchronized camera
- Pressure generators to mimic respiratory airflow and upper esophageal pressure
- Pressure sensors to monitor internal manometry
- Automated bolus injection system
Integration of a Swallowing simulation software fed and improved by the clinical data (VFS). This would enable to offer a hardware-software solution for:
- Study and diagnosis of known pathologies
- Validation of modified-texture diet according to the patient’s conditions
- Development of patient specific laryngeal/pharyngeal implants with respect to their specific swallowing disorder.
