Abstract

A medicating device for human nails and adjacent tissue which, in the preferred embodiment, includes a transparent viscoelastic gel pad having one or more pharmacologically-active substances incorporated therein; a sheet of transparent, impermeable, and elastic material providing an occlusive layer adjacent to the upper surface of the viscoelastic gel pad; an elastic retaining ring perimetrically surrounding the viscoelastic gel pad to prevent migration due to shoe pressure; and a porous meshwork attached to the elastic retaining ring so as to additionally anchor the gel pad from migration. The porous meshwork member may be located at the surface of the viscoelastic gel pad opposite the occlusive covering sheet, or may run through the viscoelastic gel pad in its anchoring function. The viscoelastic gel pad, occlusive covering sheet, and elastic retaining ring with porous meshwork may be secured to the digit of the wearer by a transparent digit-engaging elastic tubular sheath, or by an adhesive tape bandage with a visual access opening.

Claims

1. A medicating device for human nails and adjacent tissue comprising:

a. a viscoelastic gel pad, having an upper surface, a lower surface, and a lateral perimeter;

b. a flexible, elastic retaining ring formed to fit closely about the lateral perimeter of said viscoelastic gel pad;

said retaining ring having an upper surface and a lower surface, and bounding a central area wherein said viscoelastic gel pad is located;

c. an impermeable, elastic sheet member, attached about the upper surface of said retaining ring, which provides an occlusive layer adjacent to said upper surface of said viscoelastic gel pad;

d. a thin, porous meshwork affixed to said retaining ring and extending across said central area of said retaining ring to support said viscoelastic gel pad within said central area; and

e. means for attaching said viscoelastic gel pad and said flexible elastic retaining ring with affixed porous meshwork to a digit of a wearer.

2. The medicating device for human nails and adjacent tissue, as recited in claim 1, wherein said thin, porous meshwork is positioned adjacent to said lower surface of said viscelastic gel pad.

3. The medicating device for human nails and adjacent tissue, as recited in claim 1, wherein said thin, porous meshwork is positioned within and extends through said viscoelastic gel pad.

4. The medicating device for human nails and adjacent tissue, as recited in claim 1, wherein said means for affixing said medicating device for human nails and adjacent tissue to a digit of a wearer includes an adhesive bandage.

5. The medicating device for human nails and adjacent tissue, as recited in claim 4, wherein said adhesive bandage includes a window adjacent said impermeable elastic sheet member.

6. The medicating device for human nails and adjacent tissue, as recited in claim 1, wherein said means for affixing said medicating device for human nails and adjacent tissue to a digit of a wearer includes an elastic tubular digit-encasing sheath.

7. The medicating device for human nails and adjacent tissue, as recited in claim 6, wherein a portion of said elastic tubular digit-encasing sheath, located adjacent to said upper surface of said viscoelastic gel pad, is utilized as said impermeable, elastic sheet member.

8. The medicating device for human nails and adjacent tissue, as recited in claim 1, wherein said viscoelastic gel pad and impermeable, elastic sheet member are transparent.

9. The medicating device for human nails and adjacent tissue, as recited in claim 1, wherein said viscoelastic gel pad is perfused with one or more pharmacologically active agents.

10. The medicating device for human nails and adjacent tissue, as recited in claim 9, wherein said pharmacologically active agents are urea, antifungal agents, antibiotics, keratolytic agents, local anesthetics, alcohols, or proteolytic enzymes
