Diagnosis of pneumonia

    I want to offer a more efficient way to diagnose pneumonia by preventing the sample from being contaminated by oral bacteria.
    My idea is to create a device which will use air currents to separate particles from the lungs from particles originating in the mouth, ensuring that pulmonary phlegm hits the filter while the rest of the particles are routed to the lower balloon. Such a diagnostic tool could improve identification of pneumonia in children in developing nations and reduce the inappropriate use of antibiotics.
