Device

The Odon device is a new low cost instrument to deliver the fetus when complications occur during the second stage of labor. This device is made of film-like polyethylene material and may be potentially safer and easier to apply than forceps and vacuum extractor (contraindicated in cases of HIV infection) for assisted deliveries, and a safe alternative to some Caesarean sections in settings with limited surgical capacity and human resource constraints.

The use of the Odon device is very simple as shown in the images below :



1


The inserter is applied on the head of the baby. A soft plastic bell assures perfect adaptation to the fetal head and prevents damage.


2

The inserter progressively positions the Odón device around the head of the baby. Positioning occurs as the inserter gently produces the sliding of the two surfaces of the folded sleeve along the birth canal and around the baby’s head.



3

When the Odón device is properly positioned, a marker on the insertion handle become clearly visible in the reading window. A minimal and self-limited amount of air is pumped into an air chamber in the inner surface.



4

This produces a secure grasp around the head of the baby that fixes the inner surface and allows for traction. The inserter is removed.



5

The head is delivered taking advantage of the sliding effect of the two surfaces of the folded sleeve. Lubrication of the surfaces further facilitates the extraction process. If needed, traction can be applied up to 19 kg (which is equivalent to the force applied with the metal vacuum extractor).
