Limited-access, reduced-pressure systems and methods
A reduced-pressure treatment system for applying reduced pressure to a tissue site at a limited-access location on a patient includes a reduced-pressure source, a treatment manifold for placing proximate the tissue site and operable to distribute reduced pressure to the tissue site, and a sealing member for placing over the tissue site and operable to form a pneumatic seal over the tissue site. The reduced-pressure treatment system also includes a reduced-pressure bridge and a moisture-removing device on at least portion of the reduced-pressure bridge. The reduced-pressure bridge includes a delivery manifold operable to transfer the reduced pressure to the treatment manifold, an encapsulating envelope at least partially enclosing the delivery manifold and having a patient-facing side, and a reduced-pressure-interface site formed proximate one end of the reduced-pressure bridge.
1. A reduced-pressure bridge for delivering reduced pressure to a tissue site from a remote site, the reduced-pressure bridge comprising:
a first encapsulating envelope at least partially enclosing a first manifold;
a second encapsulating envelope at least partially enclosing a second manifold;
a first aperture proximate a first end of the reduced-pressure bridge and configured to be directly coupled to a sealing member that is configured to provide a fluid seal over the tissue site;
a second aperture proximate a second end of the reduced-pressure bridge and configured to be coupled to a reduced-pressure interface positioned at the remote site; and
a fenestration positioned between the first end and the second end.
2. The reduced-pressure bridge of claim 1 , further comprising a wicking material on the reduced-pressure bridge.
3. The reduced-pressure bridge of claim 2 , wherein the wicking material is adapted to contact a remote tissue portion and to absorb liquid from the remote tissue portion.
4. The reduced-pressure bridge of claim 2 , wherein the wicking material comprises a cloth-material drape.
5. The reduced-pressure bridge of claim 2 , wherein the wicking material comprises a non-woven fabric.
6. The reduced-pressure bridge of claim 2 , wherein the wicking material covers at least 50 percent of a side of the reduced-pressure bridge.
7. The reduced-pressure bridge of claim 2 , wherein the wicking material covers at least 70 percent of a side of the reduced-pressure bridge.
8. The reduced-pressure bridge of claim 2 , wherein the wicking material covers at least 80 percent of a side of the reduced-pressure bridge.
9. The reduced-pressure bridge of claim 2 , wherein the wicking material extends along a length of the reduced-pressure bridge.
10. The reduced-pressure bridge of claim 1 , wherein the first encapsulating envelope and the second encapsulating envelope comprise a polyurethane material.
11. The reduced-pressure bridge of claim 1 , wherein the reduced-pressure bridge has a length (L), and wherein L>120 mm.
12. The reduced-pressure bridge of claim 1 , wherein the reduced-pressure bridge has a length (L), and wherein L>200 mm.
13. The reduced-pressure bridge of claim 1 , wherein the reduced-pressure bridge has a length (L) and a width (W), and wherein L>(4*W).
14. The reduced-pressure bridge of claim 1 , wherein the first manifold is a foam material.
15. The reduced-pressure bridge of claim 1 , wherein the first encapsulating envelope is formed by a first encapsulating member and a second encapsulating member, and wherein the second encapsulating envelope is formed by the second encapsulating member and a third encapsulating member.
16. The reduced-pressure bridge of claim 15 , wherein the first encapsulating member has a first perimeter portion, wherein the second encapsulating member has a second perimeter portion, and wherein the first perimeter portion is coupled to the second perimeter portion.
17. The reduced-pressure bridge of claim 1 , wherein the first aperture is configured to be in fluid communication with the tissue site through the sealing member.
18. The reduced-pressure bridge of claim 1 , further comprising an adhesive on the first end configured to couple the reduced-pressure bridge to the sealing member.
19. The reduced-pressure bridge of claim 1 , wherein the reduced-pressure bridge is configured to transfer reduced pressure from the remote location to the tissue site through the first aperture.
20. The reduced-pressure bridge of claim 1 , wherein the reduced-pressure bridge is configured to distribute fluids to the tissue site.
