Low-profile reduced pressure treatment system
A low-profile reduced pressure treatment apparatus and system are provided. The apparatus includes a moldable conduit holder, a conduit through the conduit holder, and a flexible base. The conduit holder has first and second bulkhead surfaces, a convex top surface, and a bottom surface adapted to conform to a tissue contact region adjacent to a tissue site. An end of the conduit is substantially flush with the first bulkhead surface and a longitudinal axis of the conduit is substantially perpendicular to the first and second bulkhead surfaces. The base is connected on a first side to the bottom surface of the conduit holder, and extends beyond the first bulkhead surface to form an overlay zone adjacent the first bulkhead surface. An adhesive is disposed on a second side of the flexible base to secure the flexible base to the tissue contact region.
1. A reduced pressure treatment system comprising:
a moldable conduit holder having substantially parallel first and second bulkhead surfaces, a bottom surface, and a convex top surface, the bottom surface adapted to substantially conform in shape to a tissue contact region adjacent to a tissue site;
a conduit having a first portion received by the second bulkhead surface and a second portion extending longitudinally through the conduit holder to the first bulkhead surface and substantially perpendicular to the first and second bulkhead surfaces;
a base having a side connected to the bottom surface of the conduit holder, the base extending beyond the first bulkhead surface to form a bridge overlay zone adjacent the first bulkhead surface;
a porous pad having a primary delivery region configured to contact the tissue site and a porous bridge region having a side surface configured to contact the first bulkhead surface in fluid communication with the conduit and a bottom surface connected to the bridge overlay zone of the base;
a drape sized to create a sealed space around and cover the first portion of the conduit, the conduit holder, and the porous pad, wherein the conduit is substantially parallel to the tissue contact region; and
a reduced pressure source fluidly connected to the conduit to deliver reduced pressure through the conduit and the porous bridge region to the primary delivery region of the porous pad.
2. The system of claim 1 , wherein the conduit holder is formed from room-temperature-vulcanizing silicone.
3. The system of claim 1 , wherein the base is adhesively connected to the bottom surface of the conduit holder.
4. The system of claim 1 , further comprising a second conduit positioned adjacent the first conduit such that an end of the second conduit is substantially flush with the first bulkhead surface and a longitudinal axis of the second conduit is substantially perpendicular to the first and second bulkhead surfaces.
5. The system of claim 1 , wherein the conduit holder further comprises:
a first flexible membrane forming the bottom surface;
a second flexible membrane forming the top surface; and
a moldable material disposed between the first and second flexible membranes to encase the conduit between the first and second flexible membranes.
6. The system of claim 5 , wherein the first and second membranes are nitrile film.
7. The system of claim 1 , further comprising a porous extension region oriented adjacent to the primary delivery region so that the porous extension region extends into the tissue site.
8. The system of claim 1 , wherein the side surface of the porous bridge region has substantially the same cross-sectional shape as the first bulkhead surface.
9. The system of claim 1 , wherein the porous pad has a thickness and the conduit holder has a height that are substantially equal.
10. The system of claim 1 , wherein the porous pad has a top surface facing the drape which is substantially coplanar with the convex top surface of the conduct holder.
11. The system of claim 1 , wherein the side surface of the porous bridge region is substantially perpendicular to the tissue site.
12. The system of claim 1 , wherein the primary delivery region and the porous bridge region as separate components, each having a contact surface in fluid communication with each others contact surface.
13. The system of claim 12 , wherein the porous bridge region and the primary delivery region each have a top surface facing the drape that are substantially coplanar.
14. The system of claim 12 , wherein the porous bridge region has a top surface facing the drape which is substantially coplanar with the convex top surface of the conduit holder.
15. The system of claim 1 , wherein:
the primary delivery region of the porous pad is a first manifold positioned in contact with the tissue site for distributing reduced pressure to the tissue site; and
the porous bridge region of the porous pad is a second manifold positioned in fluid communication with the first manifold for distributing reduced pressure to the tissue site.
