    "device_name": "Odon Childbirth Device",
    "goal": "Provide a simple, low-trauma method to assist women during difficult or obstructed labour by gently extracting the baby's head.",
    "problem_addressed": "Complications from forceps and ventouse (maternal tissue damage, fetal skull injury, episiotomy), high maternal and neonatal mortality in low-resource settings, lack of affordable obstetric tools.",
    "concept_summary": "A double-layer plastic bag is inserted over the baby's head through the birth canal. Air is pumped into the bag, inflating a chamber that gently grips the chin without obstructing breathing. The baby can then be pulled out with reduced force, minimizing tissue damage.",
    "detailed_description": "The device originated from a bottle-cork trick. Early prototypes used a glass uterus model with two large bags; later versions employed a single flexible plastic bag that surrounds the head. An inserter instrument was later added to facilitate bag placement. Clinical testing began on a birth simulator at Des Moines University (2008) and progressed to trials on 30 women, with ongoing studies on 100 healthy women in Argentina. Trials report no pain, no episiotomy, and quick delivery. The device is intended to be low-cost, reusable, and usable by midwives without a doctor present, targeting developing-country health systems.",

        "The Odon device imitates the bottle trick. A double layer of plastic is inserted via the birth canal to surround the baby's head. Some air is then pumped into the bag, inflating a plastic chamber that gently grips the head around the chin.",
        "In the initial trials the bag was inserted using a spatula, but it wasn't easy. By the fifth birth, he had invented an inserter ... the first patient to benefit from the inserter ... I had no pain whatsoever. It was very quick and I got to enjoy watching the birth of my son.",
        "The experts could see the potential for this cheap and simple device in developing countries, where prolonged or obstructed births are often fatal.",
        "If the trials go well, Merialdi predicts the device could be in clinical use in two or three years' time. The US company that will manufacture the device, Becton Dickinson and Company, says it will sell it cheaply to developing countries."
