Postpartum hemostatic balloon is an assisted reproductive and contraceptive device commonly used in obstetrics and gynecology surgeries. It is mainly used for the control and hemostasis of postpartum hemorrhage, which can effectively reduce the amount of bleeding during surgery and improve the safety and success rate of surgery. 

Has good scalability and controllability. It is made of high-strength material and can quickly expand after inflating to fill the uterine cavity and effectively compress the uterine wall to stop bleeding.
