[0002] Postpartum hemorrhage, defined as excessive blood loss after childbirth, is the leading cause of maternal death worldwide, claiming the lives of more than 125,000 mothers each year. Uncontrolled postpartum hemorrhage can require a woman to receive multiple blood transfusions, and in severe cases, can result in a total hysterectomy or death. Therefore, if possible, it is desirable to control it at the onset of such postpartum hemorrhage. In about 80% of cases, the cause of postpartum hemorrhage is uterine atony, i.e., the failure of the uterus to contract after childbirth in a woman. Risk factors for uterine atony include prolonged labor, preeclampsia, and multiparity. Thus, there is a need for a system that can quickly induce uterine contractions, thereby reducing or completely stopping uterine bleeding.

[0003] Therefore, based on this, the PCT international patent with application number 201980090205.4 discloses a postpartum uterine hemorrhage device, which comprises: an elongated body configured to be connectable to a vacuum source; a flexible annular portion connected to the elongated body and configured to be placeable in a uterus, the flexible annular portion including a plurality of holes on an inner circumference of the flexible annular portion, wherein activation of the vacuum source is configured to draw a vacuum through the plurality of holes to contract the uterus when the elongated body is inserted into the uterus; a guard folded around an outer circumference of the annular portion, and the guard having a rim extending radially inward relative to the flexible annular distal portion, the guard configured to prevent tissue from obstructing the plurality of holes when vacuum is applied; and an inflatable seal connected to the elongated body and configured to seal the uterus.
