The device being tested here did not emerge from the polished halls of a medical university, but from the curiosity of Jorge Odón, a mechanic in Lanús, Argentina. After watching a video demonstrating how to extract a cork from the inside of a wine bottle using a plastic bag, Odón built his first prototype in his kitchen using his daughter’s doll and a glass jar. His mechanical intuition suggested that positive air pressure could guide a child into the world more gently than the heavy iron of forceps, which have remained largely unchanged for over a century.
This simple shift in physics—using an inflated sleeve to secure the fetal head—was the focus of a workshop held in Addis Ababa this April. The gathering marked the conclusion of the "Assist Ethiopia" study, a collaboration between Doctors with Africa CUAMM, the Fonds d’Innovation pour le Développement, and the Besançon Regional University Hospital. For the first time, the device was tested in an African clinical setting, specifically targeting the complications that arise when labor becomes dangerously prolonged.
The significance of the trial lies in the stark reality of rural Ethiopian healthcare. While the World Health Organization suggests a ten percent cesarean section rate for medical necessity, the national average here lingers between two and three percent. When labor stops, there is often no one trained to use a vacuum extractor or forceps—tools that require years of specialized experience to master without causing injury. The OdonAssist is designed to be used by midwives and health workers in peripheral facilities, potentially stopping a complication before it necessitates a long journey to a tertiary hospital.
The device could avoid complications due to delay by enabling local management of difficult births.
As Manenti and his colleagues presented their findings to health policymakers, the conversation shifted from the mechanics of the device to its human application. In a country where obstructed labor accounts for up to a quarter of neonatal deaths, the arrival of a sleeve of air represents a rare moment where a mechanic’s parlor trick meets the urgent needs of a mother in a distant highland ward.
