While doing fieldwork at rural health clinics in Mexico, we observed that children in the midst of an asthma attack were forced to travel hundreds of miles to an urban hospital receive treatment. This was despite the fact that their local doctor could diagnose the symptoms of asthma and had ample supply of the proper medication. We discovered that the missing link was a spacing device that could ensure the delivery of asthma medication to the lungs of the suffering child. We set out to design a spacer that could accomplish this while remaining inexpensive enough to be affordable throughout the developing world.
