Flexible, collapsible, dome or cylinder-shaped bonnet that provides a substantially airtight fit to a fetal head and utilizes frictional and internally-created vacuum forces for assisting childbirth. The bonnet is manually inserted and rolled over the cranium of the fetus, stopping short of the eyes and the ears. Friction and internally created vacuum forces are created when the bonnet is pulled, thus securing the bonnet to the fetus's head and allowing orientation and delivery. The device is comprised of a dome or cylinder-shaped body made of a collapsible elastic material, an optional raised "lip" located on the exterior of the open end, and may have a mechanical extension attached to the closed end. System embodiments allow for the attachment to the exterior of the closed end grommets and/or mechanical extensions that will irreversibly stretch, lengthen, and expose warning alerts in the event that excessive longitudinal force is applied. The bonnet is a significant improvement because it allows a firmer grip on the fetus' head with less danger of damage to either the mother or the fetus. Thus traction and rotational forces may be safely applied to a fetus without the need to use forceps or hard suction cups.
A method of manufacturing an obstetric traction delivery bonnet apparatus comprising a smooth, rollable dome or cylinder having an inner surface, an outer surface, an open end with an edge, a completely closed end, walls, and sized to provide a snug fit to a fetal head, wherein said apparatus is fitable around a fetal head to have adherence thereto because of frictional and internally-created vacuum forces, comprising the steps of:
