This study introduces a novel cup simulation tool for children with swallowing disorders, enabling customized cup designs to control liquid flow rates and prevent choking. The simulation aids in developing safer drinking solutions for pediatric dysphagia.
Area of Science:
- Biomedical Engineering
- Pediatric Medicine
- Fluid Dynamics
Background:
- Children with swallowing disorders struggle with traditional cups, facing difficulties initiating suction and controlling flow rates, leading to choking risks.
- Existing cup designs do not adequately address the unique needs of pediatric patients with dysphagia.
Purpose of the Study:
- To develop and validate a novel simulation tool for designing adaptive drinking cups for children with swallowing disorders.
- To improve the safety and efficacy of drinking cups for pediatric dysphagia management.
Main Methods:
- A new cup design tool integrating fluid-cup interactions and Petri net formulation with fluid flow principles.
- Development of a parametric cup simulation for visualization and microcontroller prototyping.
- Modeling of a vent-based controller and simulated pouring studies with varying parameters.
Main Results:
- Generation of volumetric flow rate curves over time, compared against target flow rates.
- Simulation results demonstrated predictable behavior across variations in cup design parameters and liquid properties.
Conclusions:
- The developed simulation model supports rapid prototyping for dysphagia research.
- It allows for precise tuning of cup geometry, liquid parameters, and control signals to meet individual user needs.
- Facilitates the creation of customized drinking solutions for children with swallowing difficulties.
