Abstract:
Asthma is a chronic disease which cannot be cured, hut can be controlled with appropriate medication.
Asthma medication mostly involves with DPI and MDl inhalers MDl inhaler is coupled with a spacer device W improve the drug inhalation. Design and improvement in affordability and performance analysis of the spacer device is the main objective of the project The geometric shapes of the spacer devices which have a great influence on its performance were modeled and ( IT) simulations were obtained for the existing devices. By analyzing the CFD simulation a new design was developed in order to reduce the stagnant area and to maximize the drug delivery I low patterns inside the newly developed spacer device were analyzed using CFD simulation and obtained results were used to validate the design. Proposed new design was finalized with higher performance and improved affordability
