Stephen John and Joseph Barnett from Western Michigan University both created a simple oscillatory relief valve for dual pressure lung treatment, reports Machine Design.

In underdeveloped countries, dual-pressure treatment is often unavailable because extra equipment is expensive, difficult to operate, or hard to upkeep. Recognizing this deficiency, Stephen John and Joseph Barnett, two engineering students at Western Michigan University (WMU), invented the NeoVent, an easy-to-operate dual-pressure device aimed at helping premature babies breathe.
