Abstract

A bandage is disclosed comprising a lower portion and a matrix. The lower portion has an upper surface, a base plate on the upper surface, and a post extending from the surface of the base plate. The matrix is attached to the lower portion by means of a hole extending through the matrix which fits around the post. The upper surface of the lower portion can be adhesively coated if desired. The lower portion can also be in the form of a strap. The base plate can be composed of a suitable barrier material such as metal foil or metal foil - polyester laminates. If desired, the matrix can be of a material which can dispense medicaments such as trinitroglycerol.

Claims

1. A bandage comprising:

(a) a lower portion comprising

(1) a first layer having an upper surface;

(2) a base plate having an upper face and a lower face, said lower face being attached to said upper surface of said first layer, said base plate having a surface area less than the surface of said upper surface of said first layer;

(b) a post extending upwardly from the upper face of said base plate; and

(c) a matrix having an upper surface and a lower surface and a hole extending from said lower surface to said upper surface, said lower surface being in intimate contact with the upper face of said base plate, said post passing through said hole.

3. The bandage of claim 1 or 2 wherein said base plate is a metal foil.

5. The bandage of claim 1 or 2 wherein said matrix has a surface area less than the surface area of said base plate.

7. The bandage of claim 3 wherein said metal foil is a laminate containing aluminum foil and a polyester layer.

8. The bandage of claim 1 or 2 wherein in said post is adhesively attached to said base plate.

9. The bandage of claim 1 or 2 wherein said post is attached to said base plate by a rivet extending through said base plate and said first layer.

10. The bandage of claim 1 or 2 wherein said post is attached to said base plate by a rivet extending through said base plate.

11. The bandage of claim 1 or 2 wherein the hole in said matrix is defined by an eyelet.

12. The matrix of claim 1 or 2 wherein said matrix contains a medicament.

13. The bandage of claim 1 or 2 wherein said matrix comprises a series of concentric matrices having a central matrix.

14. The bandage of claim 13 wherein said hole is located in said central matrix.

15. The bandage of claim 1 wherein the first layer of said lower portion is a strap.

16. The bandage of claim 15 wherein said strap comprises opposite faces each having a flexible fabric fastener of an interconnectable series of loops and hooks.

17. The bandage of claim 1 or 2 wherein said matrix includes a laminate containing aluminum foil and a polyester.

18. The bandage of claim 17 wherein said matrix comprises a layer of polyethylene, a layer of aluminum foil, a thin layer of polyethylene, and a layer of polyester.

19. The bandage of claim 18 wherein said matrix further comprises a layer containing a medicament.

20. The bandage of claim 19 wherein said medicament is trinitroglycerol.

21. The bandage of claim 1 or 2 wherein said post has a bottom next to said base plate, at some point said post having a greater cross sectional area than the cross sectional area at a point immediately closer to said bottom.

22. The bandage of claim 1 or 2 wherein said post has a length shorter than the thickness of said matrix.

2. A bandage comprising:

(a) a lower portion comprising;

(1) a first layer having an adhesively coated upper surface; and

(2) a base plate having an upper face and a lower face, said lower face being attached to said adhesively coated upper surface of said first layer, said base plate having a surface area less than the surface area of said adhesively coated upper surface of the first layer;

(b) a post extending upwardly from the upper face of said base plate; and

(c) a matrix having an upper surface and a lower surface and a hole extending from said lower surface to said upper surface, said lower surface being in intimate contact with the upper face of said base plate, said post passing through said hole.

4. The bandage of claim 2 further comprising a release liner in contact with the adhesively coated upper surface of said first layer.

6. The bandage of claim 4 wherein said release liner surrounds said base plate.
