Reduced-pressure dressing assemblies for use in applying a closing force
A closing dressing bolster and assembly for use with a system for treating a linear wound on a patient includes a bolster body formed from a flexible closing bolster material having closing members that are operable to develop an inward closing force when the closing dressing bolster is placed under reduced pressure. In one aspect, when the closing dressing bolster is under reduced pressure, the system, dressing, or assembly develops an inward force realized at the linear wound and a compression force. A wicking-material holder and wicking material may be used as well. The member components may all be see-through to allow visual inspection of the wound without requiring removal of the dressing.
1. A dressing assembly, comprising:
a closing dressing bolster for treating a wound, comprising:
a bolster body formed from a flexible closing bolster material,
a first closing member formed on a lower surface of the bolster body,
a second closing member formed on the lower surface of the bolster body,
at least one oblique wall between the first closing member and the second closing member; and
an over-drape configured to form a seal over the bolster body.
2. The dressing assembly of claim 1 , wherein the bolster body is formed from silicone.
3. The dressing assembly of claim 1 , wherein the bolster body is configured to develop a bending moment about a center area of the bolster body when the closing dressing bolster is placed under reduced pressure.
4. The dressing assembly of claim 1 , wherein the first closing member and the second closing member are configured to move toward each other when the closing dressing bolster is placed under reduced pressure.
5. The dressing assembly of claim 1 , wherein the bolster body is configured to allow light to pass through such that color may be detected from a location external to the closing dressing bolster.
6. The dressing assembly of claim 1 , wherein the lower surface of the bolster body is a tissue-facing surface.
7. The dressing assembly of claim 1 , wherein the first closing member is formed on a first lateral side of a center area of the bolster body, and wherein the second closing member is formed on a second lateral side of the center area.
8. The dressing assembly of claim 1 , wherein the bolster body comprises a top wall and a bottom wall coupled in a spaced relationship to form a hollow region.
9. A closing dressing bolster for treating a wound, comprising:
a bolster body comprising a top wall and a bottom wall coupled in a spaced relationship to form a hollow region;
a first closing member formed on the bottom wall of the bolster body
a second closing member formed on the bottom wall of the bolster body; and
an oblique wall on the bottom of the bolster body between the first closing member and the second closing member.
10. The closing dressing bolster of claim 9 , wherein the first closing member is formed on a first lateral side of a center area of the bolster body, and wherein the second closing member is formed on a second lateral side of the center area.
11. The closing dressing bolster of claim 9 , wherein the bolster body is formed from silicone.
12. The closing dressing bolster of claim 9 , wherein the bolster body is configured to develop a bending moment about a center area of the bolster body when the closing dressing bolster is placed under reduced pressure.
