A vacuum delivery model (or vacuum extraction simulator) is an anatomical training tool used by healthcare professionals to practice assisting with childbirth during the second stage of labor. It features a life-size pelvis and a fetus with a flexible skull, allowing trainees to master techniques for applying suction (ventouse) to the fetal head to facilitate vaginal delivery. 

Key Aspects of the Vacuum Delivery Model (Training Tool)

• Anatomical Accuracy: Designed with realistic pelvic landmarks, soft skulls with fontanelles, and articulated joints to simulate various fetal positions.
• Simulation Capabilities: Used to train in the full process of vacuum application: engagement, flexion, descent, rotation, and extraction of the fetus.
• Target Audience: Ideal for obstetricians, midwives, nursing colleges, and medical schools to enhance skills in managing obstructed labor.
• Types: Available in various models, such as the ESAW VD-154 or specific Kiwi Vacuum Cup training systems. 

Clinical Context of Vacuum Delivery (The Procedure)

• Mechanism: A soft or hard plastic cup is applied to the baby's head, and suction is created using a pump to assist with traction while the mother pushes.
• Indications: Used to assist in childbirth if labor is stalled in the second stage, or if fetal distress is identified, often as an alternative to forceps.
• Safety & Risks: The procedure requires an empty bladder and a fully dilated cervix, and must be terminated if it fails (e.g., 3+ pop-offs) to prevent injury to the fetus, such as cephalhematoma.
