Obstructed labor accounts for 8% of maternal deaths in developing countries, ranging from 7-45% in Africa, which amounts to approximately 42,000 deaths annually. Assisted vaginal delivery by forceps or vacuum extraction can be effective during prolonged second stage or when maternal effort is lacking. Vacuum extraction requires less training and has fewer associated risks than forcep delivery and does not require surgical facilities.
Symphisiotyomy, a minimally invasive procedure that involves dividing the cartilage of the symphysis pubis and temporarily enlarging the pelvis 1-3 cm requires vacuum extraction and can be performed in lieu of a cesarean section if there are inadequate trained personnel or surgical facilities. Many existing vacuum devices break down easily, are unused because personnel are not trained, or run on electricity, which is not always available, especially in rural areas.
The goal of this project is to develop a vacuum extraction device that can be used by a range of health care providers in resource limited settings. The final design consists of two major parts, an applicator and an extraction component. The applicator is composed of three separate units: a pronged component with three prongs, a cone, and a handle.
Understanding the subtle cultural difficulties in the setting of intended use is close to impossible without the full immersion into that setting. Without knowing the true difficulties and how they are managed, other teams who we have had contact with have difficulty meeting the demands of their end users. Other student design teams struggle to fully understand the user requirements and find it hard to achieve them with a completed prototype based off literature before initiating contact with the end user.
