Abstract: Uterine toner device (UTD) for reducing postpartum hemorrhage includes fundal, cervical, vaginal, and nipple portions with cylindrical and tubular shaped bodies. The fundal and cervical portions include fenestrations. The diameters for fenestrations in the fundal portion are larger than those in the cervical portion. An indication resides between the fundal and cervical portions for proper placement. When the nipple portion couples to a pressure pump's suction tube and negative pressure is applied, cervical tissue is drawn into the fenestrations in the cervical portion resulting in contraction and retraction of the uterus, stopping any bleeding. The pressure pump is automatically shut-off after a pre-set period of time to avoid prolonged ischemia. A balloon at the cervical portion assists in the release of the cervical tissue when inflated. During a C-section, an introducer may be used in combination with the UTD to assist in introducing the suction tube through a tight cervix.
