Abstract

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.

Claims (29)

1. A method for treating a linear wound on a patient, the method comprising the steps of:

deploying a see-through dressing assembly over the linear wound and on top of the patient's epidermis;

deploying a see-through sealing member over the see-through dressing assembly and a portion of the patient's epidermis to form a fluid seal; and

providing reduced pressure to the see-through dressing assembly whereupon a closing force that is substantially within the plane of the patient's epidermis is developed;

wherein the see-through dressing assembly includes a closing dressing bolster that comprises a first closing member and a second closing member;

reduced pressure from the reduced pressure source causes a bending moment about a center portion of the closing dressing bolster; and

the bending moment causes the first closing member and second closing member to develop the closing force.

2. The method of claim 1 wherein the see-through dressing assembly comprises the closing dressing bolster formed from see-through silicone.

3. The method of claim 1 , wherein the see-through dressing assembly also develops a compressive force.

4. A method for treating a linear wound, the method comprising:

placing a closing dressing bolster having a first closing member and a second closing member over the linear wound;

placing a sealing member over the closing dressing bolster;

providing a fluid seal between the sealing member and an epidermis proximate to the linear wound;

fluidly coupling the sealing member to a reduced pressure source; and

activating the reduced pressure source to cause a bending moment about a center portion of the closing dressing bolster that causes the first closing member and the second closing member to develop a closing force substantially within a plane of the epidermis on the linear wound;

wherein the closing dressing bolster and the sealing member are comprised of a material that allows for sufficient light to pass through such that at least one characteristic of the linear wound may be observed from a point external to the closing dressing bolster.

5. The method of claim 4 , wherein the material is silicone.

6. The method of claim 4 , wherein the closing dressing bolster comprises a window such that the window is drawn closer to the wound under reduced pressure and the characteristic becomes observable through the window.

7. The method of claim 4 , wherein the closing dressing bolster comprises a transparent silicone window such that the window is drawn closer to the wound under reduced pressure and the characteristic becomes observable through the window.

8. The method of claim 4 , wherein the closing dressing bolster comprises a movable portion that moves aside to allow the characteristic to be observed if reduced pressure is removed from the closing dressing bolster.

9. The method of claim 4 , wherein the closing dressing bolster comprises a first portion and a second portion that overlap under reduced pressure and separate if reduced pressure is removed.

10. A method for treating a linear wound, the method comprising:

placing a closing bolster having a first closing member and a second closing member on a portion of an epidermis over the linear wound;

applying a sealing subsystem over the closing bolster and the epidermis to provide a seal against the epidermis;

delivering a reduced pressure from a reduced-pressure subsystem to the closing bolster;

wherein the closing bolster, sealing subsystem, and reduced-pressure subsystem are operable to cause a bending moment about a center portion of the closing bolster to develop a closing force substantially within a plane of the epidermis and to deliver reduced pressure to the linear wound;

wherein the closing bolster and the sealing subsystem comprise a material that allows light to pass such that characteristics of the linear wound may be perceived from a place external to the system.

11. The method of claim 10 , wherein the material is a soft polymer.

12. The method of claim 10 , wherein the material is silicone.
