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 closing dressing bolster for treating a linear wound, comprising:
a bolster body formed from a flexible closing bolster material and having a center portion;
the bolster body comprising:
a top wall and a bottom wall, the top wall and the bottom wall coupled in a spaced relationship to form a hollow region,
the bottom wall having a first lateral portion on one side of the center portion, and a second lateral portion on another side of the center portion,
a first closing member formed on the first lateral portion, and
a second closing member formed on the second lateral portion;
wherein the first closing member and the second closing member define therebetween, a treatment trough having oblique walls.
2. The closing dressing bolster of claim 1 , wherein the bolster body is formed from a see-through material.
3. The closing dressing bolster of claim 1 , wherein the bolster body is formed from silicone.
4. The closing dressing bolster of claim 1 , wherein the bolster body further comprises a wicking-material holder, and wherein the closing dressing bolster further comprises a wicking material associated with the wicking-material holder.
5. A closing dressing bolster for treating a linear wound, comprising:
a bolster body formed from a flexible closing bolster material;
the bolster body comprising:
a first closing member formed on a bottom wall of the bolster body and having a first oblique wall,
a second closing member formed on the bottom wall of the bolster body and having a second oblique wall,
a wicking-material holder formed by a gap between the first closing member and second closing member,
a wicking material disposed within the wicking-material holder, the wicking material having a fluid flow pathway for removing fluids; and
wherein the first closing member and second closing member are operable, when the closing dressing bolster is under reduced pressure, to move towards one another to develop an inward force.
6. The closing dressing bolster of claim 5 , wherein the first closing member and second closing member are operable, when the closing dressing bolster is under reduced pressure, to develop a compression force.
7. The closing dressing bolster of claim 5 , wherein the bolster body is formed from a see-through material.
8. The closing dressing bolster of claim 5 , wherein the bolster body is formed from silicone.
9. The closing dressing bolster of claim 5 , wherein the first closing member is formed on a first lateral side of a center portion of the bolster body and the second closing member is formed on a second lateral side of the center portion, and wherein the bolster body is operable to develop a bending moment about the center portion when the closing dressing bolster is placed under reduced pressure.
10. A closing dressing bolster for treating a linear wound, comprising:
a bolster body formed from a flexible closing bolster material;
a first closing member formed on a tissue-facing surface of the bolster body, the first closing member formed on a first lateral side of a center area and comprising a first compartment;
a second closing member formed on the tissue-facing surface of the bolster body, the second closing member formed on a second lateral side of the center area and comprising a second compartment;
a wicking material holder formed by a gap between the first closing member and the second closing member and a wicking material associated with the wicking material holder:
wherein the first closing member and second closing member are operable to move towards each other when placed under reduced pressure;
wherein the bolster body is operable to develop a bending moment about the center area when the closing dressing bolster is placed under reduced pressure; and
wherein the bolster body is operable to allow light to pass through sufficiently that color may be detected from a location external to the closing dressing bolster.
11. The closing dressing bolster of claim 10 , wherein the bolster body is formed from silicone.
12. A method of manufacturing a closing dressing bolster for treating a linear wound, comprising:
forming a bolster body from a flexible closing bolster material;
wherein forming the bolster body comprises forming the bolster body with a first lateral side and a second lateral side, and wherein bolster body includes a central area, and wherein the first lateral side is on one side of the central area and the second lateral side on another side of the central area; and
wherein forming the bolster body further comprises:
forming a first closing member on the bolster body on the first lateral side of the central area,
forming a second closing member on the bolster body on the second lateral side of the central area,
forming the bolster body to develop a compressive force when placed under reduced pressure,
forming a gap between the first closing member and the second closing member to provide a wicking material holder,
wherein the bolster body is operable to develop a bending moment about the central area when the closing dressing bolster is placed under reduced pressure, and
wherein the first closing member and second closing member develop an inward closing force when the closing dressing bolster is placed under reduced pressure.
13. The method of claim 12 , wherein forming the bolster body further comprises forming the bolster body from a see-through material.
14. The method of claim 12 , wherein forming the bolster body further comprises forming the bolster body from silicone.
15. The method of claim 12 , wherein forming the bolster body further comprises providing a wicking material associated with the wicking material-holder.
