Abstract/Summary
Womb-a aims to design a safe, minimally invasive, and effective product that solves the issue of removing retained placentas after childbirth reducing the risk of infection and uterine trauma. Womb-a brings a handheld motorized device that can be used at the bedside immediately after delivery of a baby. Retained placentas happen to approximately 1-3% of deliveries [1] which elevates the likelihood of postpartum infection and hemorrhaging. Current solutions include manual removal, windmill technique, and D&C which individually have severe issues such as elevating risk of infection, inconsistent removal of adhered placenta, and surgical complications. The Womb-a aims to mitigate these risks by creating a tool which can be used in the hospital setting by an OBGYN to reduce infection and procedural uterine trauma. The Womb-a is a handheld device that includes an applicator that enters the patient vaginally and rotates inside the uterus to remove placenta tissue while suctioning the residual tissue through its central lumen. This early design highlights effectiveness and a concept to an issue which millions of women face postpartum.
