A 22-year-old college student in the UK, who suffered from acute asthma since he was a child, has developed an inhaler which signals whether a user has taken the right dosage.
Josh Averill, an undergraduate in product design at Nottingham Trent University in UK, claims his invention has the potential to alleviate people’s symptoms by helping ensure they administer the medicine correctly.
Manufactured using 3D printing, the inhaler features a piezo sensor that measures airflow as it passes through it. If the user breathes in correctly — and in doing so increases the airflow — a green LED lights up. But if an inadequate amount is inhaled, a red one illuminates.
Two buzzes are also sounded; the first to signal when the user should start to inhale and the second to let him know when to stop holding his breath.
Josh undertook research with 60 different people including school children, fellow university students and older people.
