Uterine hemorrhage controlling system and method
An insertable device is designed to control uterine hemorrhaging after birth by facilitating contractile movement of the uterus. An insertable device comprises a tube having a connecting portion and a suction portion and a seal positioned along the length of the connecting portion proximal to the suction portion. Upon insertion of the suction portion and seal into the uterus, the seal abuts a vaginal canal and forms a seal between a vaginal opening and the uterus. The suction portion comprises a first loop having an opening that is oriented away from an interior wall of the uterus when inserted into the uterus. The connecting portion of the tube couples to a pump that when actuated generates a negative pressure within the uterus, resulting in a uniform mechanical stimulus to the uterine wall in order to facilitate tamponade and contractile movement of the tissue.
1. An insertable device comprising:
a tube having a connecting portion configured for coupling to a vacuum source, and a suction portion configured for insertion into a uterus, the suction portion including a single loop having a first branch and a second branch that are separated from each other, the first branch and the second branch respectively including an outer wall and a channel having a surface protrusion; and
a bridge fluidically coupled to the suction portion, the bridge having a mating protrusion extending from distal ends thereof to secure the bridge to the suction portion via insertion into the channel of the first branch and the second branch, each mating protrusion having a cavity that complements and receives via insertion the surface protrusion of the first branch and the second branch; and
a plurality of disk-shaped seals positioned along a length of the connecting portion proximal to the suction portion, the diameter of each disk-shaped seal incrementally decreases such that a largest disk-shaped seal of the plurality of disk-shaped seals is closest to the suction portion and the smallest disk-shaped seal of the plurality of disk-shaped seals is farthest away from the suction portion.
2. The insertable device of claim 1 , wherein the connecting portion and the suction portion are separate components that couple together.
3. The insertable device of claim 1 , wherein the connecting portion and the suction portion have a unitary construction.
4. The insertable device of claim 1 , wherein the tube is manufactured as an extrusion.
5. The insertable device of claim 4 , wherein the extrusion comprises a constant cross-section.
6. The insertable device of claim 4 , wherein the extrusion comprises at least one groove extending down the length of the suction portion of the extrusion.
7. The insertable device of claim 6 , wherein the at least one groove is positioned between edges of the extrusion.
8. The insertable device of claim 1 , wherein the bridge separates the distal ends of the first branch and the second branch by a distance.
9. The insertable device of claim 8 , wherein the length of the bridge prevents the first branch and the second branch from collapsing into each other.
10. The insertable device of claim 1 , wherein the tube is composed of a flexible material.
11. The insertable device of claim 1 , wherein the connecting portion is configured to couple to a container that collects biological materials from the uterus.
12. The insertable device of claim 11 , wherein the container is configured to indicate an amount of biological materials collected.
13. An insertable device comprising:
a tube having a connecting portion for insertion into a uterus, the tube formed as a single loop having a first branch and a second branch that are separated from each other, the first branch and the second branch respectively including an outer wall and a channel having a surface protrusion;
a bridge fluidically coupled to the tube, the bridge having a mating protrusion extending from distal ends thereof to secure the bridge to the tube via insertion into the channel of the first branch and the second branch, each mating protrusion having a cavity that complements and receives via insertion the surface protrusion of the first branch and the second branch; and
a plurality of disk-shaped seals positioned along a length of the tube, the diameter of each disk-shaped seal incrementally decreasing in size.
14. The insertable device of claim 13 , wherein the tube is manufactured as an extrusion.
15. The insertable device of claim 14 , wherein the extrusion comprises a constant cross-section.
16. The insertable device of claim 14 , wherein the extrusion comprises at least one groove extending down the length of a portion of the extrusion.
17. The insertable device of claim 16 , wherein the at least one groove is positioned between edges of the extrusion.
18. The insertable device of claim 13 , wherein the bridge separates the distal ends of the first branch and the second branch by a distance.
19. The insertable device of claim 18 , wherein the length of the bridge prevents the first branch and the second branch from collapsing into each other.
20. The insertable device of claim 13 , wherein the tube is composed of a flexible material.
