Abstract: An embodiment of a uterine hemorrhage controlling system comprises a suction module including a suction end coupleable to a pump by a connecting tube, and a sealing module coupled to the suction module. The system may further comprise the pump and a filter coupled to the suction module. A uterine hemorrhage controlling method comprises: shielding a suction module that has been delivered into a uterus; sealing an entrance into the uterus while the suction module is situated within the uterus; applying a negative pressure within the uterus upon activation of a pump; and maintaining the negative pressure within the uterus to induce uterine contraction. The method may further comprise delivering the suction module into the uterus; transmitting bodily fluids, out of the uterus through the suction module, and filtering the bodily fluids.

Abstract: A joint for use with a space frame for connecting a plurality of struts together. The joint permits dome fabrication and erection with essentially no field bolting required. A central hub is included in the joint for resisting forces transmitted to the joint by dome struts.

Abstract: A roof strut permits easy attachment of roof covering material thereto. The strut has a channel defined therein and a clamping bar is positioned within the channel to sandwich roof covering material between that bar and the strut to form a gasketless seal.
