Abstract: A body fluid regulating apparatus includes an inner tube disposed inside an outer tube with a gap between the inner and outer tubes, the inner tube being formed with apertures that are larger in size than apertures formed in the outer tube. A fluid adaptor is sealingly coupled to a proximal portion of the inner tube. The fluid adaptor includes a vacuum port adapted to be coupled to a vacuum source for creating a negative pressure in the inner tube. The outer tube is adapted for uterine tissue to press thereagainst. An inflatable plug is disposed on the outer tube.
