It is recommended that therapeutic medicine be inhaled every day as a treatment for asthma. Through the close observation of users, the pain points of existing products were identified, making it possible to pursue ideal usability. Tubes and switches on the unit were placed in easily accessible positions, and hiding the vent under the surface of the housing makes it easier to clean. The medicine bottle size is also very easy for children to handle. The rounded mask is easy to wear in any position, even when sleeping. The design perfectly balances the elaborate elements of a medical device and a home appliance.
