Reduced-pressure dressing assemblies for use in applying a closing force
View Patent ↗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 for use with a system for treating a linear wound on a patient, the dressing assembly comprising:
a bolster body formed from a flexible closing bolster material, the bolster body having a first surface and a second, tissue-facing surface;
wherein the bolster body comprises:
a top wall and a bottom wall, the top wall and bottom wall coupled in a spaced relationship to form a hollow region, the bottom wall having a first lateral side on one side of a center wound area and a second lateral side on another side of the center wound area,
a first closing member on the first lateral side of the center wound area of the bolster body;
a second closing member on the second lateral side of the center wound area of the bolster body;
wherein the first closing member and second closing member are operable, when the bolster body is under reduced pressure, to move towards one another and to develop a compressive force; and
an over-drape for disposing adjacent to the first surface of the bolster body and operable to form a seal over the bolster body.
2. The dressing assembly of claim 1 wherein the bolster body is formed from a see-through material.
3. The dressing assembly of claim 1 wherein the bolster body is formed from silicone.
4. The dressing assembly of claim 1 further comprising a wicking-material holder formed in the bolster body and a wicking material associated with the wicking-material holder.
5. The dressing assembly of claim 1 wherein the bolster body is formed from a see-through material and wherein the bolster body is operable to allow light to pass through sufficiently that color of the linear wound may be seen from a point external to the dressing assembly.
