Postpartum hemorrhage, defined as postpartum excessive blood loss, is the leading cause of maternal death worldwide, taking over 125000 mothers' lives each year. Failure to control postpartum hemorrhage may require the maternal blood to be transfused multiple times, in severe cases, possibly leading to total hysterectomy or death. It is therefore desirable to control this post-partum bleeding at the beginning, if possible. In about 80% of cases, postpartum hemorrhage is due to uterine contractions and weakness, i.e., the inability of women to contract their uterus after delivery. Risk factors for uterine contractions include prolonged labor, preeclampsia and labor-intensive. Thus, there is a need for a system that can rapidly cause uterine contractions, thereby reducing or completely stopping uterine bleeding.
