A vacuum extractor is a medical device used during childbirth to assist in delivering a baby. It consists of a soft cup that attaches to the baby's head and a vacuum pump that creates suction. This helps guide the baby out of the birth canal when the mother is having difficulty pushing. The vacuum extractor is typically used when there are concerns about the baby's heart rate or if labor is prolonged. It is considered a safer alternative to forceps, as it is less likely to cause injury to both the mother and the baby. Proper training is essential for healthcare providers using this tool.
