Project Description:
Asthma is a chronic respiratory disease that affects over 27 million people in the US, with 10 people dying daily. Most of these deaths are completely preventable, but due to the complicated process of administering medication through inhalers, patients fail to receive proper care. Conventional devices like Metered Dose Inhalers (MDIs), Dry Powder Inhalers (DPIs), and Nebulizers require precise technique and posture, yet 94% of patients report incorrect usage. To address this, we developed an MDI-canister-compatible smart inhaler capable of delivering asthma medication more effectively by automating the administration process. Our prototype senses lip placement, posture, inhalation/exhalation flow, and the number of canister shakes, then actuates medication release when optimal conditions are met. The medication is only administered once inhalation is sensed (breath actuated) and the user lifts the cap lever. This enhances usability and promotes correct administration. By improving patient outcomes and reducing hospital visits, the device can free up clinical resources. While upfront costs may raise concerns about health equity, they may be offset by reductions in long-term care expenses, offering an overall ethical and practical benefit.
