See-through, reduced-pressure dressings and systems
A see-through dressing assembly is presented for use with a reduced-pressure system for treating a wound on a patient using reduced pressure that allows visual observation of the wound during treatment. The dressing assembly includes a bolster for providing a directed force when under reduced pressure, a sealing member for covering the bolster and providing a seal over the bolster and a patient's epidermis, and wherein the bolster and sealing member are formed from see-through materials sufficient to allow perception of color from a point external to the system. Other systems, dressings, and methods are presented.
1. A see-through dressing assembly for use with a reduced-pressure system for treating a linear wound on a patient, the see-through dressing assembly comprising:
a closing dressing bolster for providing a closing force when under reduced pressure, the closing dressing bolster comprising:
a top wall,
a bottom wall, the top wall and bottom wall are coupled in a spaced relationship, the bottom wall having a center portion, a first lateral portion, and a second lateral portion,
a first closing member formed on the first lateral portion, and
a second closing member formed on the second lateral portion;
a sealing member for covering the closing dressing bolster and providing a seal over the closing dressing bolster;
wherein the closing dressing bolster and sealing member are formed from see-through materials sufficient to allow perception of color from a point external to the see-through dressing assembly; and
wherein the geometry of the closing dressing bolster causes a bending moment to develop about the center portion when the closing dressing bolster is subject to reduced pressure, the bending moment causing the first closing member and second closing member to develop the closing force, and the closing force being directed downward and inward relative to the linear wound.
2. The see-through dressing assembly of claim 1 wherein the first closing member and second closing member are operable to move towards each other under reduced pressure.
3. The see-through dressing assembly of claim 1 wherein the sealing member comprises an sealing member made from a see-through elastomeric material.
4. The see-through dressing assembly of claim 1 wherein the closing dressing bolster comprises see-through silicone.
5. The see-through dressing assembly of claim 1 wherein the sealing member comprises a sealing member made from a see-through elastomeric material and the closing dressing bolster is formed of see-through silicone.
6. A dressing assembly for use with a reduced-pressure treatment system on a patient, the dressing assembly comprising:
a closing dressing bolster for placing over a wound on the patient and for providing a closing force when under reduced pressure, the closing dressing bolster comprising:
a top wall and a bottom wall, wherein the top wall and bottom wall are coupled in a spaced relationship, the bottom wall having a center portion, a first lateral portion, and a second lateral portion,
a first closing member formed on the first lateral portion, and
a second closing member formed on the second lateral portion;
a sealing member for covering the closing dressing bolster and providing a seal over the closing dressing bolster and a patient's epidermis;
a visual inspection device for visually detecting color of the wound on the patient from a location external to the dressing assembly, wherein the visual inspection device comprises a bolster material with structural elements spaced apart broadly enough to allow color to be perceived through the bolster material and a see-through sealing member; and
wherein the closing dressing bolster comprises a gap between the first closing member and second closing member that forms a wicking material holder.
7. The dressing assembly of claim 6 wherein the visual inspection device comprises a see-through material used to form the sealing member and the closing dressing bolster comprises a see-through material.
8. The dressing assembly of claim 6 wherein the bolster material comprises a non-opaque foam.
9. The dressing assembly of claim 6 wherein the bolster material comprises a bolster mesh.
10. The dressing assembly of claim 6 wherein the visual inspection device further comprises a bolster window disposed on the bolster material such that when the bolster window is pressed against the bolster material by reduced pressure, color may be detected through the bolster material and bolster window.
11. The dressing assembly of claim 6 wherein the sealing member comprises a see-through elastomeric material.
12. The dressing assembly of claim 6 wherein the closing dressing bolster comprises silicone and the sealing member comprises a see-through elastomeric material.
