Abstract

Combinations of medical adhesive composites, e.g., dressings, and a package in which the medical adhesive composites are attached to a release surface on the bottom sheet of the package are disclosed. The dressings may include a flexible backing and carrier. Methods of manufacturing and using the combination are also disclosed.

Claims

1. A method for making a combination of a medical adhesive composite in a package comprising the steps of:

(a) providing a medical adhesive composite including a substrate having top and bottom faces and a pressure sensitive adhesive on the bottom face of the substrate;

(b) providing a bottom sheet of packaging material having a cohesive material located thereon;

(c) providing a release surface between the bottom sheet of packaging material and the adhesive on the bottom face of the substrate, the release surface comprising a release coating applied over a portion of the cohesive material on the bottom sheet, wherein the bond between the release coating and the cohesive material on the bottom sheet is stronger than the bond between the release coating and the adhesive;

(d) providing a top sheet of packaging material over the medical adhesive composite, the top sheet including a cohesive material located thereon, wherein the medical adhesive composite is located between the top and bottom sheets; and

(e) sealing the top sheet to the bottom sheet about the periphery of the medical adhesive composite using the cohesive material on the top and bottom sheets of packaging material.

2. The method of claim 1, further comprising attaching a carrier to at least a portion of the top face of the substrate.

3. The method of claim 2, wherein the step of attaching a carrier comprises attaching the carrier to at least a substantial portion of the periphery of the substrate.

4. The method of claim 2, wherein the step of attaching a carrier comprises attaching the carrier to substantially the entire top face of the substrate.

5. The method of claim 2, wherein the step of attaching a carrier comprises attaching two opposing portions of carrier on opposing sides of the substrate.

6. A method of using a combination adhesive composite dressing and package comprising the steps of:

(a) providing a combination comprising;

(1) medical adhesive composite comprising;

(A) a substrate having top and bottom faces;

(B) a pressure sensitive adhesive coated on at least a portion of the bottom face of the substrate; and

(2) a package housing the medical adhesive composite comprising;

(A) a top sheet located over the top face of the substrate, the top sheet including a layer of cohesive material on at least a portion of the top sheet;

(B) a bottom sheet located under the adhesive on the bottom face of the substrate, the bottom sheet comprising a layer of cohesive material located over substantially all of the bottom sheet, wherein the medical adhesive composite is located between the top and bottom sheets, and further wherein the top and bottom sheets are sealed to each other about the periphery of the medical adhesive composite by the layers of cohesive material on the top and bottom sheets; and

(C) a release surface at least as large as the pressure sensitive adhesive, the release surface comprising a release coating applied over a portion of the layer of cohesive material on the bottom sheet, wherein the bond strength between the release coating and the cohesive material on the bottom sheet is greater than the bond strength between the release coating and the adhesive on the bottom face of the medical adhesive composite;

(b) separating at least a portion of the top sheet from the bottom sheet to expose the medical adhesive composite;

(c) separating the adhesive on the bottom face of the substrate from the release surface, wherein the medical adhesive composite is removed from the bottom sheet of the packaging material;

(d) applying the adhesive and attached substrate to a patient.

7. The method of claim 6, wherein the medical adhesive composite further comprises a carrier attached to at least a portion of the top face of the substrate.

8. The method of claim 7, further comprising the step of removing the carrier from the substrate after the substrate is attached to a patient.

9. A combination of a medical adhesive composite in a package comprising:

(a) a medical adhesive composite comprising;

(1) a substrate having top and bottom faces;

(2) a pressure sensitive adhesive coated on at least a portion of the bottom face of the substrate; and

(b) a package housing the medical adhesive composite comprising;

(1) a top sheet located over the top face of the substrate of the medical adhesive composite;

(2) a bottom sheet located under the adhesive on the medical adhesive composite;

(3) cohesive material on at least a portion of the top sheet and over substantially all of the bottom sheet, the cohesive material on the top sheet being opposed to and facing cohesive material on the bottom sheet, wherein the top and bottom sheets are sealed to each other about the periphery of the medical adhesive composite by the cohesive material; and

(4) a release surface at least as large as the pressure sensitive adhesive on the medical adhesive composite, the release surface comprising a release coating applied over the cohesive material on the bottom sheet, wherein the bond strength between the release coating and the cohesive material on the bottom sheet is greater than the bond strength between the release coating and the adhesive on the medical adhesive composite.

10. The combination of claim 9, further comprising a carrier attached to at least a portion of the top face of the substrate.

11. The combination of claim 10, wherein the carrier is heat sealed to the substrate.

12. The combination of claim 10, wherein the bond strength between the carrier and the substrate is greater than the bond strength between the adhesive on the bottom face of the substrate and the release surface.

13. The combination of claim 10, wherein the bond strength between carrier and the substrate is less than the bond strength between the adhesive on the substrate and the skin of a patient.

14. The combination of claim 10, wherein the carrier is attached to at least a substantial portion of the periphery of the substrate.

15. The combination of claim 10, wherein the carrier is attached to substantially the entire top face of the substrate.

16. The combination of claim 10, wherein the carrier comprises two opposing portions located on opposing sides of the substrate.

17. The combination of claim 10, wherein the substrate comprises a conformable elastomeric film.

18. The combination of claim 17, wherein the substrate is selected from the group consisting of polyurethane film, polyester film, polyether block amide film and combinations thereof.

19. The combination of claim 9, wherein the medical adhesive composite further comprises a pad positioned on the bottom face of the substrate.

20. The combination of claim 19, wherein the pad contains one or more substances selected from the group consisting of antimicrobial agents, drugs, chemical indicators, and combinations thereof.

21. A method for making a combination of an adhesive composite dressing in a package comprising the steps of:

(a) providing a composite dressing including a backing having top and bottom faces and a pressure sensitive adhesive on the bottom face of the backing;

(b) attaching a carrier to at least a portion of the top face of the backing, the carrier supporting the backing;

(c) providing a bottom sheet of packaging material;

(d) providing a release surface between the bottom sheet of packaging material and the adhesive on the bottom face of the backing, the release surface attached to the bottom sheet, wherein the bond between the release surface and the bottom sheet is stronger than the bond between the release surface and the adhesive;

(e) providing a top sheet of packaging material over the composite dressing wherein the composite dressing is located between the top and bottom sheets;

(f) sealing the top sheet to the bottom sheet about the periphery of the composite dressing; and

(g) printing production information on at least one of the top and bottom sheets of packaging material, the printing being performed in-line with the steps of sealing the top and bottom sheets of packaging material and sealing the top and bottom sheets.
