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.

Claims (15)

1. A uterine hemorrhage controlling method comprising:

shielding a suction module having a suction end that has been delivered transvaginally into a uterine cavity;

sealing an entrance into the uterine cavity while the suction end is situated within the uterine cavity;

applying a negative pressure within the uterine cavity; and

maintaining the negative pressure within the uterine cavity, thus inducing uterine contraction;

wherein sealing the entrance comprises sealing the entrance at a location within a vaginal canal.

2. The method of claim 1 , wherein shielding the suction module comprises providing a barrier configured to prevent obstruction of the suction end.

3. The method of claim 1 , wherein sealing the entrance comprises inflating a balloon configured to substantially fill a vaginal cross-section.

4. The method of claim 1 , wherein sealing the entrance comprises producing a radial expansion of a membrane seal.

5. The method of claim 1 , wherein sealing the entrance comprises providing a porous seal configured to deform into an expanded configuration upon absorption of a fluid.

6. The method of claim 1 , further comprising coupling the suction module to a pump.

7. The method of claim 1 , wherein applying the negative pressure comprises applying a negative pressure of up to 3 psi within the uterus.

8. The method of claim 1 , wherein maintaining the negative pressure comprises maintaining the negative pressure for between 1 and 24 hours.

9. The method of claim 1 , wherein maintaining the negative pressure within the uterine cavity comprises obstructing a connection between the suction module and the pump.

10. The method of claim 1 , further comprising delivering the suction end of the suction module into the uterine cavity; transmitting bodily fluids, out of the uterine cavity through the suction module; and filtering the bodily fluids.
