An adhesive dressing comprises a substrate formed by an apertured removal layer embedded within an adhesive layer, wherein the removal layer facilitates easy and a traumatic removal of the dressing from a patient's skin. The removal layer may takes the form of an open net-like material that may extend beyond one or more edges of the adhesive layer for grasping with the fingers, attaching auxiliary devices, or other purposes.

What is claimed is: 1. A laminate for attachment to a patient's skin, comprising: an adhesive layer of an adhesive adapted for removable attachment at one surface thereof to the patient's skin; and a removal layer embedded within said adhesive layer at or flush with said one surface, said removal layer defining a plurality of openings with said adhesive passing therethrough, wherein said adhesive has a greater adherent affinity for said removal layer than for the patient's skin. 2. The laminate of claim 1, wherein said adhesive is a pressure sensitive adhesive material. 3. The laminate of claim 1, wherein said removal layer includes between 5 and 100 openings per square centimeter. 4. The laminate of claim 1, wherein said removal layer is sized so that a portion of said removal layer projects beyond a portion of the periphery of said adhesive layer sufficient to be grasped for removal of the laminate from the patient's skin. 5. The laminate of claim 1, further comprising a backing layer on a surface of said adhesive layer opposite said one surface. 6. The laminate of claim 1, further comprising a release liner removably covering said one surface of said adhesive layer. 7. The laminate of claim 1, wherein said openings of said removal layer constitute at least five percent (5%) of the total surface area of the removal layer. 8. The laminate of claim 1, wherein said removal layer is formed from a material selected from the group of a warp-knit netting, a non-woven scrim, an extrusion formed netting, and an open-cell foam. 9. The laminate of claim 1, wherein said removal layer is formed from a material that is electrically or thermally conductive for conduction from an external source. 10. The laminate of claim 1, wherein said removal layer is formed of an absorbent material. 11. The laminate of claim 1, wherein said adhesive layer is formed of a water absorbent material. 12. A laminate for attachment to a patient's skin, comprising: an adhesive layer of an adhesive adapted for removable attachment at one surface thereof to the patient's skin; and a removal layer embedded within said adhesive layer at or flush with said one surface, said removal layer defining a plurality of openings with said adhesive passing therethrough, wherein said removal layer is sized so that a portion of said removal layer projects beyond a portion of the periphery of said adhesive layer. 13. The laminate of claim 12, wherein said adhesive is a pressure sensitive adhesive material. 14. The laminate of claim 12, wherein said removal layer includes between 5 and 100 openings per square centimeter. 15. The laminate of claim 12, further comprising a backing layer on a surface of said adhesive layer opposite said one surface. 16. The laminate of claim 12, further comprising a release liner removably covering said one surface of said adhesive layer. 17. The laminate of claim 12, wherein said openings of said removal layer constitute at least five percent (5%) of the total surface area of the removal layer. 18. The laminate of claim 12, wherein said removal layer is formed from a material selected from the group of a warp-knit netting, a non-woven scrim, an extrusion formed netting, and an open-cell foam. 19. The laminate of claim 12, wherein said removal layer is formed from a material that is electrically or thermally conductive for conduction from an external source. 20. The laminate of claim 12, wherein said removal layer is formed of an absorbent material. 21. The laminate of claim 12, wherein said adhesive layer is formed of a water absorbent material. 22. A method for forming an adhesive laminate comprising the steps of: providing a release liner; overlaying the release liner with a removal layer having a plurality of openings therethrough; and impressing an adhesive onto the removal layer so that adhesive becomes embedded within the plurality of openings and so that the adhesive contacts the release liner, to thereby form an adhesive layer with the removal layer embedded within said adhesive at or flush with a surface of said adhesive adapted for removable attachment to a patient's skin. 23. The method of claim 22, further comprising applying a backing layer to the exposed surface of the adhesive layer. 24. The method of claim 22, wherein the step of impressing the adhesive includes embedding the removal layer so that the removal layer is at the surface of the adhesive layer in contact with the release liner. 25. The method of claim 22, wherein the step of impressing the adhesive includes embedding the removal layer so that the removal layer is adjacent the surface of the adhesive layer in contact with the release liner.
