Abstract

A padding and medicating device for corns, hammertoes, bunions, blisters, and the like comprising a noncompressible, thermoplastic, oleaginous, viscoelastic gel directly impregnated onto a carrier structure of elastic fabric. The ultrasoft gel is retained on and compressed against the body part being treated by the elastic tension of the fabric which causes the noncompressible gel to expand radially outward, flow over the lesion, and conform to the shape of the lesion in a manner which dissipates externally-applied pressure equally throughout the fabric-gel-tissue system. The invention also internally absorbs frictional or horizontal shearing forces, delivers a therapeutically significant dose of a lubricating, soothing, and emolifying oil such as Mineral Oil U.S.P., and is further capable of delivering a pharmacologically active substance to the foot lesion.

Claims

1. A padding device for the human foot, comprising:

a. a tubular sleeve of elastic fabric fitting about a digit and having an inside surface, an outside surface and opposing ends;

b. said tubular sleeve of elastic fabric being formed of a seamless tubular material which spontaneously rolls inwards about each end of said tubular sleeve to form a cuff thereat; and

c. a pad of viscoelastic gel;

d. said pad of viscoelastic gel being directly impregnated onto said inside surface of said tubular sleeve of elastic fabric.

2. The padding device, as recited in claim 1, where the viscoelastic gel includes plasticizing oil in the form of Mineral Oil U.S.P.

3. The padding device, as recited in claim 2, where the plasticizing oil is perfused with an oil soluble medicinal agent.

4. The padding device, as recited in claim 1, wherein said pad of viscoelastic gel is capable of being stretched at least 200 percent of any resting dimension without tearing.

5. The padding device, as recited in claim 1, wherein the viscoelastic gel is thermoplastic in nature.

6. The padding device, as recited in claim 1, wherein, additionally, there is a second pad of viscoelastic gel which is impregnated directly upon the outside surface of said tubular sleeve.

7. The padding device, as recited in claim 1, wherein the pad of viscoelastic gel is of uniform thickness.

8. The padding device, as recited in claim 1, wherein the pad of viscoelastic gel varies in thickness.

9. A padding device for the human foot, comprising:

a. an elastic fabric member having a portion in the form of a tubular sleeve to encircle a digit of the human foot and a non-tubular portion which extends from said digit encircling tubular sleeve to lie adjacent to a metatarsophalangeal joint associated with said digit;

b. said tubular sleeve portion of said elastic fabric member being closed at the distal end so as to encompass the distal end of said digit to prevent migration of the padding device; and

c. a pad of viscoelastic gel;

d. said pad of viscoelastic gel being directly impregnated onto said non-tubular portion of said elastic fabric member so as to be positioned adjacent to said metatarsophalangeal joint.

10. The padding device, as recited in claim 9 above, wherein, additionally, an elongated strap of elastic fabric is attached to said non-tubular portion of said elastic fabric member, said elongated strap of elastic fabric being formed to encircle the metatarsal region of the human foot.

11. The padding device, as recited in claim 9 above, where said pad of viscolastic gel varies in thickness.

12. The padding device, as recited in claim 9, wherein said viscoelastic gel includes Mineral Oil U.S.P. as a plasticizer.

13. The padding device, as recited in claim 12, wherein said plasticizer includes an oil soluble medicinal agent.

14. The padding device, as recited in claim 9, wherein said viscoelastic gel is thermoplastic.

15. The padding device, as recited in claim 9, wherein said pad of viscoelastic gel is capable of being stretched at least 200 percent of any resting dimension without tearing.

16. A padding device for the human foot, comprising:

a. an elastic fabric member having a portion in the form of a tubular sleeve to encircle a digit of the human foot and a non-tubular portion which extends from said digit encircling tubular sleeve to lie adjacent to a metatarsophalangeal joint associated with said digit;

said tubular sleeve having an inside surface and an outside surface;

b. a first pad of viscoelastic gel being directly impregnated onto said non-tubular portion of said elastic fabric member so as to be positioned adjacent to said metatarsophalangeal joint; and

c. a second pad of viscoelastic gel which is directly impregnated upon said outside surface of said tubular sleeve encircling said digit so as to lie between, and separate, said digit and a second, adjacent digit.
