Abstract

An affixable pad for corns, calluses, bunions, and the like, made from a soft viscoelastic gel material. Preferably, the gel contains a high percentage of plasticizing oil such as Mineral Oil U.S.P. The gel is impregnated onto an elastic fabric, such as Spandex, which allows the gel to flow around a lesion and equalize pressure in a superior manner.

Claims

1. An affixable soft tissue padding device comprising:

(a) a sheet of flexible fabric;

(b) a layer of gelatinous viscoelastic padding material impregnated onto one surface of said sheet of flexible fabric; and

(c) a layer of pressure-sensitive adhesive coating the surface of said sheet of flexible fabric opposite the surface impregnated with said layer of gelatinous viscoelastic padding material.

2. The affixable soft tissue padding device of claim 1 wherein said layer of gelatinous viscoelastic padding material is of uniform thickness.

3. The affixable soft tissue padding device of claim 1 wherein said layer of gelatinous viscoelastic padding material varies in thickness.

4. The affixable soft tissue padding device of claim 1 wherein said layer of gelatinous viscoelastic padding material is confluent over the entire surface of the sheet of flexible fabric.

5. The affixable soft tissue padding device of claim 1 wherein said layer of gelatinous viscoelastic padding material is limited to a circumscribed area on the surface of said sheet of flexible fabric.

6. The affixable soft tissue padding device of claim 1 wherein said sheet of flexible fabric is elastic in nature.

7. An affixable soft tissue padding device comprising:

(a) a sheet of flexible fabric;

(b) a circumscribed layer of gelatinous viscoelastic padding material impregnated on a portion of one surface of said sheet of flexible fabric; and

(c) a layer of pressure-sensitive adhesive coating the remainder of same surface of said sheet of flexible fabric as said gelatinous viscoelastic padding material.

8. The affixable soft tissue padding device of claim 7 wherein said layer of circumscribed gelatinous padding material is of uniform thickness.

9. The affixable soft tissue padding device of claim 7 wherein said layer of circumscribed gelatinous padding material varies in thickness.

10. The affixable soft tissue padding device of claim 7 wherein said sheet of flexible fabric is elastic in nature.

11. The affixable soft tissue padding device of claim 7 wherein said circumscribed layer of gelatinous viscoelastic padding material is dusted with one or more of the following powders:

talc, corn starch, antifungal powder, or antiperspirant powder.

12. The affixable soft tissue padding device of claim 7 wherein said layer of gelatinous viscoelastic padding material contains more than 50 percent plasticizing oil.

13. The affixable soft tissue padding device of claim 12 wherein said plasticizing oil is Mineral Oil U.S.P.

14. The affixable soft tissue padding device of claim 12 wherein said plasticizing oil contains a dissolved medicinal agent from one or more of the following categories:

antifungal agents, keratolytic agents, or antiperspirant agents.
