Claims
- 1. A hydrocolloid bandage for use on a wound site comprising at least:
a hydrocolloid region, wherein the hydrocolloid region has a hydrocolloid upper surface area having an upper surface area length and a hydrocolloid lower surface area having a lower surface area length, and wherein the hydrocolloid region has a hydrocolloid end extending for an end length between the hydrocolloid upper surface area and the hydrocolloid lower surface area; and a film layer adhered to the hydrocolloid upper surface area and hydrocolloid end length, the film layer having a film length and a film lower surface area, wherein the film layer has a film length which exceeds the upper surface area length and hydrocolloid end length, and wherein the film layer extends beyond the hydrocolloid end such that a bandage lower surface area is formed by the hydrocolloid lower surface area and the film lower surface area extending beyond the hydrocolloid end to a film end.
- 2. A hydrocolloid bandage for use on a wound site comprising at least:
a hydrocolloid region, wherein the hydrocolloid region has a hydrocolloid upper surface area having an upper surface area length and a hydrocolloid lower surface area having a lower surface area length, and wherein the hydrocolloid region has a hydrocolloid end extending for an end length between the hydrocolloid upper surface area and the hydrocolloid lower surface area; and an adhesive layer film layer adhered to the hydrocolloid upper surface area and hydrocolloid end length having an adhesive layer length and an adhesive layer upper surface area, wherein the adhesive layer length exceeds the upper surface area length and hydrocolloid end length, and wherein the adhesive layer extends beyond the hydrocolloid end such that a bandage lower surface area is formed by the hydrocolloid lower surface area and the adhesive lower surface area extending beyond the hydrocolloid end to an adhesive end; and a film layer adhered to the adhesive layer upper surface area.
- 3. The hydrocolloid bandage of claim 1, wherein the bandage further comprises an adhesive layer adhered to the bandage lower surface area.
- 4. The hydrocolloid bandage of claim 1, 2 or 3, wherein the hydrocolloid upper surface area and the hydrocolloid lower surface area are substantially parallel, and wherein the hydrocolloid end is at an angle substantially perpendicular to the hydrocolloid upper and lower surface areas.
- 5. The hydrocolloid bandage of claim 4, wherein the hydrocolloid upper surface area and the hydrocolloid lower surface area are substantially parallel, and wherein the hydrocolloid end is linear.
- 6. The hydrocolloid bandage of claim 4, wherein the hydrocolloid upper surface area and the hydrocolloid lower surface area are substantially parallel, and wherein the hydrocolloid end has a radius of curvature of 1″-3″.
- 7. The hydrocolloid bandage of claim 1, 2 or 3, wherein the hydrocolloid upper surface area and the hydrocolloid lower surface area are substantially parallel, and wherein the hydrocolloid lower-surface area length exceeds the hydrocolloid upper surface area length, and wherein the hydrocolloid end is at an angle of less than about 90° to the hydrocolloid lower surface area.
- 8. A hydrocolloid bandage for use on a wound site comprising at least:
a hydrocolloid region, wherein the hydrocolloid region has a hydrocolloid upper surface area having an upper surface area length and a hydrocolloid lower surface area having a lower surface area length, and wherein the hydrocolloid region has a hydrocolloid end between the hydrocolloid upper surface area and the hydrocolloid lower surface area; the hydrocolloid region having the hydrocolloid upper surface area and hydrocolloid lower surface area are substantially not parallel to one another, and further wherein the hydrocolloid upper surface area length exceeds that of the hydrocolloid lower surface area length, and wherein the hydrocolloid upper surface area extends directly to the lower surface area at an angle of less than about 60°; and a film layer adhered to the hydrocolloid upper surface area, the film layer having a film length and a film lower surface area, wherein the film layer has a film length which exceeds that of the upper surface area length, and wherein the film layer extends beyond the upper surface area length.
- 9. The hydrocolloid bandage of claim 1 or 2 wherein the film layer extends from the hydrocolloid end for a distance of about 5 mm.
- 10. A hydrocolloid bandage of claim 1, wherein the adhesive layer is about 0.5 to about 8 mils.
- 11. A hydrocolloid bandage of claim 1, wherein the film layer is about 0.5 to about 10 mils.
- 12. A hydrocolloid bandage of claim 1, further comprising a release liner adhered to the bandage lower surface area.
- 13. A hydrocolloid bandage of claim 1, wherein at least one of the adhesive layer, film layer, or hydrocolloid region are substantially transparent or clear.
- 14. A hydrocolloid bandage of claim 1, wherein at least one of the adhesive layer, film layer, or hydrocolloid region are substantially flesh colored.
- 15. A method of using the hydrocolloid bandage of claim 1 comprising obtaining the bandage and applying the bandage lower surface area to a user's skin or wound site.
- 16. A bandage comprising a water absorbent hydrocolloid region having a thickness and an upper surface area and a lower surface area and a hydrocolloid end extending between the upper surface area to the lower surface area,
a flexible film layer affixed to the hydrocolloid upper surface area having affixed, wherein the flexible film layer has a film thickness and the film is formed such that the film extends over the hydrocolloid upper surface area and at least beyond the hydrocolloid end; and optionally a removable liner on the hydrocolloid lower surface area.
- 17. A bandage of claim 16, wherein the film thickness is greater than ¼ of the sum of the hydrocolloid thickness and the film thickness.
- 18. A bandage comprising a hydrocolloid region for contacting a wound site, and a flexible film layer covering one side of the hydrocolloid region; and including a bandage region extending outwardly beyond the hydrocolloid region at a selected distance, of less than about 5 mm, the bandage region being devoid of hydrocolloid.
- 19. A bandage of claim 18, further comprising a liner removably attached to a side of the hydrocolloid region opposite from the flexible film layer.
- 20. A bandage of claim 18, wherein the selected distance is less than about 5 mm.
- 21. A bandage of claim 18, wherein the selected distance is greater than about 5 mm.
