5,000 people with asthma end up in the hospital each day. It’s a number that’s at least partially avoidable, since as many as 75% of patients are using their inhalers improperly.

The T-Haler, a prototype designed by Cambridge Consultants, is an inhaler that trains patients in using inhalers. Fitted with Wi-Fi and sensors, the T-Haler can sense how it’s being used and give real-time feedback on a computer screen. The design firm claims that, with just three minutes of training with the T-Haler, proper use of inhalers skyrockets from 20% to 60%.
