Abstract: The adjustable uterine compression apparatus for postpartum hemorrhage includes at least one belt adapted for encircling the uterus transversely, the belt having keeper loops so that the belt can be cinched to continuously adjust the degree of compression applied to the uterine arteries. The belt may also be shortened and used to apply compression to the ovarian arteries. Preferably, a plurality of belts are applied spaced apart axially along the body and cervix of the uterus. The belts may be applied separately and independently, or may be embedded or incorporated into a sheet or vest that may be applied posteriorly behind the uterus and further secured by straps extending over the fundus that are cinched to at least one of the transverse belts to apply axial compression, in addition to transverse compression of the uterus. The belt(s) and vest may be made of polyglactin mesh, so that they are bioabsorbable.
