The project “Development of an Active Compression System for Venous Disease” refers to a pneumatic controller system along with a modular type silicone made Active Compression System, its implementation and validation as a treatment for the chronic venous disease. The modern invasive treatments which are currently used have side effects such as cicatrices, rashes and hyper pigmentation. Hence the unwillingness of the patients to continue with the procedure of surgeries were dominant.
Considering the noninvasive treatment methods of graduated compression with an admissible pressure profile considered as the gold standard of treatment, the pneumatic controller was designed and manufactured so that the required standard pressure profiles could be obtained using the designed Active Compression System by maintaining a uniform pressure along the leg circumference.
The numerical simulations were done by ABAQUS simulation software and a massive support was given by FEA Simulation Center, Rubber Research Institute, Ratmalana, Sri Lanka to run the simulations to validate the results of the project.
